     FIELD OF THE INVENTION 
     The present invention generally relates to electrical and electronic skin care technology and more particularly to a skin care specimen dispenser and its application in achieving personalized or customized specimen according to each individual user&#39;s own unique skin condition, skin feature and skin care need. 
     BACKGROUND 
     Skin care products in today&#39;s market are generally in the forms of lotion, cream, serum, powder, solid, gel, liquid or other physical forms. It is a universal practice in the commercially available skin care products that these products are marketed and provided to users in these forms without specification or means that are designed to meet the specific skin condition of different individual users. Consequently, the different skin types of different users after using the same skin care product can usually produce different skin care results, even though the functional ingredients of the same product are identical. For example, a skin care product marketed as “anti-aging” usually targets the aging signs of the facial skin, including wrinkles, age spots, fine lines, brown spots, smile lines, and puffy eyes, etc. By using a product targeting to reduce multiple signs of aging, which generally includes multiple active ingredients, with a single or a group of ingredients functioning to reduce certain type of aging sign, a user with stronger wrinkles or a user with stronger puffy eyes may not experience the same level of effectiveness of aging sign reduction as compared to a normal user with a more evenly weighted aging signs. 
     The inventor realizes that the way that the existing skin-care products are produced and marketed, and the method that is generally practiced by users on daily basis are lack of the ability to customize the skin care product composition and application method to match to the unique skin condition and unique skin care need of each individual user. By enabling this ability to customize the skin care product composition and application method to each individual skin care need, more effectiveness from the skin care product and better skin care result shall be achieved than the existing method of using existing skin-care products. 
     It is an object of this invention to include the step of each individual user skin analysis in the skin care process and to provide a specimen dispensing device that utilizes the unique personal skin data of each individual user resulting from said skin analysis and enables the customizability of skin care products and dispensing of skin care specimen. It is an object of this invention to provide the said specimen dispensing device in combination with skin treatment members to enhance skin care results. It is an object of this invention to utilized personal computing devices, personal communication devices, databases, internet cloud, social networks and professional skin care service providers to achieve the customized skin care for each individual user. 
     It is yet another object of this invention to provide a specimen dispensing device that enables the customizability of other health care or personal products according to each individual user&#39;s unique skin care need by utilizing data communication protocols that can associate and correlate the functions and efficacies of different specimens with the unique skin conditions of different users. 
     SUMMARY OF THE INVENTION 
     In this invention, we described a specimen dispensing device that can achieve individually customizable skin care product. We also described methods to achieve individually customized skin care specimen according to each individual user&#39;s own unique skin care need. Similar methods and devices can also be used for other health care and personal care needs, as long as the ability to individually customize a specimen can make a beneficial improvement in the health care or personal care effectiveness and provide better care result. 
     The most preferred specimen dispensing device for dispensing one or more types of specimen to a target skin area of a human being according to this invention may include: a device body; a dispenser containing the specimen; a specimen outlet existing on the device body, the outlet being operatively connected to the dispenser, where the specimen passes through during a dispensing operation; at least one electrical contact being electrically connected to an electronic circuit included in the dispenser; at least one first information storage component located in the dispenser storing first type of information; a control unit containing electronic circuits and embedded software; an electrical connection between the dispenser and the control unit; at least one second information storage component located in the control unit storing second type of information; and at least one information processing component in the control unit controls the dispensing of specimen from the dispenser by processing the first type and second type of information.

       FIG. 1  and  FIG. 2  illustrate a specimen dispenser being integrated within a specimen dispensing device  10 .  FIG. 1  is a schematic diagram illustrating a front view of the specimen dispensing device  10 , where the outside rectangle shape is shown merely for description purpose and in practice can be any other shapes as needed.  FIG. 2  is a schematic diagram illustrating a cross-sectional view along the center line  101  of  FIG. 1 . 
     The specimen dispensing device, as illustrated in  FIG. 1  and  FIG. 2 , which represents the one of the best modes of this invention, contains the following components or aspects: a device body  11 , a dispensing surface  12 , a dispenser  14 , at least one electrical contact  141  that is part of the dispenser  14 , at least one type of information storage component  142  included or embedded in the dispenser  14 , a specimen outlet  15 , an electronic control unit  17 , an electrical interface  140 , at least one information storage component  171  included in the control unit  17 , and at least one information processing component  172  included in the control unit  17 . 
     The device body  11  provides a case or housing for the dispenser and the internal electronics. It can be made of metal, alloy, glass, plastics or any other solid materials. 
     The dispensing surface  12  is a surface which allows the dispensed specimen  19  to temporarily reside upon after being dispensed from dispenser  14  through the outlet  15  of device  10  before transferring to target skin area of a user of the dispensing device  10 . However, in other embodiment, the specimen can be dispensed directly onto the target skin without staying on surface  12 , for example through a spray function, whereas the specimen  19  is dispensed from the outlet  15  through a spray action and directly upon the target skin area of the user of the dispensing device  10 . 
     The skin treatment specimen dispenser  14 , which can be in any shape, contains skin treatment specimen  19  which can be, but not limited to, liquid, gel, cream, paste, serum, lotion and powder. 
     The at least one electrical contact  141  resides on the dispenser  14  and is electrically connected to electronic circuits and components, including the information storage component  142 , that are embedded in dispenser  14 . 
     The at least one type of information storage component  142  included in the dispenser  14  stores information including how the specimen  19  is designed to be dispensed from the dispensing device  10  according to the user&#39;s own unique skin care need. The information stored in information storage component  142  can be, but not limited to, dispensing amount, dispensing speed, timing of dispense and specimen information. 
     The specimen outlet  15  is one hole or an array of holes, which is located on the surface  12  and is embedded in the body  11 . In operation, the skin treatment specimen  19  is dispensed through the outlet  15 . 
     The electronic control unit  17  contains electrical circuits, electronic components and necessary software or firmware stored in the electronic components. 
     The electrical interface  140  is located between the dispenser  14  and the electronic control unit  17  such that the dispensing of specimen  19  from the dispenser  14  can be entirely or partially controlled by the electronic control unit  17 . 
     The at least one information storage component  171  included in the control unit  17  is located in, and electronically coupled to, the control unit  17 . It stores information related to how to control the dispensing of specimen  19  from dispenser  14 , such information can be, but not limited to, software or firmware, device operation data, user skin information data, user personal and biometrics information, dispenser identification data, date, time, season, and other user-specific data such as preference, schedule, reminder message and avoidance. Such stored information may be updated as needed, by user, by a manufacturer, by a skin care specialist, by a dermatologist, or by a health care professional. The user skin information stored in information component  171  is acquired after a skin analysis of the user&#39;s skin condition. 
     Now referring to  FIG. 51 .  FIG. 51  illustrates a method to analyze a user&#39;s skin condition, as well as generation and storage of unique user data  4934 . In the user skin analysis method of  FIG. 51 , skin analysis step is characterized into two practices : objective skin analysis  5101  and subjective skin analysis  5102 . Objective skin analysis  5101  includes practices to analyze a user&#39;s skin condition by any of: skin analysis instruments, physical tools, skin feature measuring or grading equipment, which analyze the user&#39;s skin condition by a set of standards that are not affected by human judgement. Subjective analysis  5102  includes practices to analyze a user&#39;s skin condition through visual examination of user&#39;s skin, verbal or visual communication with the user regarding the user skin condition, by any of: a skin care specialist, a skin dermatologist, a computer interface allowing user to perform self-evaluation. Subjective analysis  5102  results include any of: an opinion, an evaluation, a judgement, a recommendation, or an adjustment by any of: a skin care specialist, a skin dermatologist, or the user&#39;s own preference, desire, habit, and life style.  FIG. 51  shows that the results from the practice of objective skin analysis  5101  of the user&#39;s skin, can be brought into a subjective skin analysis step  5102  as shown by step  5112 , where the user&#39; skin analysis results may be further modified by the subjective skin analysis step  5102 . 
     Results from user&#39; skin analysis by the objective skin analysis  5101  and subjective skin analysis  5102  may each be forwarded to a grading step of the condition of various skin features as indicated by steps of  5113 ,  5114 ,  5123  and  5124 . The grading step may provide a quantitative skin feature grading  5103 , which grades the user&#39;s skin features according to a set of standards and into numeric or digital information, for example grade 1 through 10 in step of 1, where grade 1 is mildest and grade 10 is strongest of a specific skin feature. The grading step may also provide a qualitative skin feature grading  5104 , which grades the user&#39;s skin features according to a set of standards and into qualitative grades, for example, very serious, serious, normal, good, and very good, whereas the qualitative grades may be less precise or provides less detail as compared to quantitative grades and may sometimes be based on personal opinion and experience of a skin specialist, a skin dermatologist, or the user. The qualitative grades from the qualitative skin features grading  5104  may also be stored or transmitted in later steps by numeric or character data, for example grade 1 through grade 5 in step of 1 representing qualitative grades of very serious, serious, normal, good, and very good. 
     Skin features as being analyzed in user&#39; skin analysis by the objective skin analysis  5101  and subjective skin analysis  5102 , and graded by quantitative skin feature grading  5103  and qualitative skin feature grading  5104  may include any of, but not limited to: fine lines, wrinkles, skin contours due to aging, loss of fat, skin drooping, brown/dark spots, discoloration, dryness, oiliness, hydration level, skin symptoms (for example, acne, blister, infection), skin chemical PH value, skin surface chemical composition, skin surface bio-composition (old skin, microbes, bacteria). Results from quantitative skin feature grading  5103  and qualitative skin feature grading  5104  may also include any of: the number, the size, the location, the strength or severity, and the distribution of each skin feature. The skin features may not be limited to facial skin but also other parts of the user&#39;s body. For different users undergoing the same skin analysis steps and skin feature grading steps, the types of skin features or skin conditions may be same or similar. However, the quantitative grade or the qualitative grade of each skin feature after quantitative skin feature grading  5103  and qualitative skin feature grading  5104  may be different for different user. For example, after quantitative skin feature grading  5103 , a first user may have a fine line grade of 10 and a wrinkle grade of 1, i.e. more fine lines issue, while a second user may have a fine line grade of 2 and wrinkle grade of 10, i.e. more wrinkles issue, whereas first and second users may require different skin care specimen composition due to different skin feature strength. 
     User&#39;s skin features and their grades after quantitative skin feature grading  5103  or qualitative skin feature grading  5104  may be further transferred as shown by step  5130  and step  5140  and be compiled into unique user data  4934 . Additionally, user&#39;s biometrics data  5105 , user&#39;s own living or working environment data  5106 , user&#39;s own skin care schedule or skin care habit data  5107 , may also be transferred, as shown by steps  5150 ,  5160  and  5170  respectively, to be compiled into the unique user data  4934 . 
     The unique user data  4934  may include any of, but not limited to: quantitative and qualitative grading of user&#39;s skin features, degree of improvement required or needed in quantitative values or qualitative grades of each feature, user&#39;s biometrics data, user&#39;s own living or working environment data, user&#39;s own skin care schedule or skin care habit data. The unique user data  4934  may be compiled in a format of a standard data communication protocol, for example the user data structure  5300  of  FIG. 53 , for data transmission, data storage and interfacing through various devices and specimen dispensers. The unique user data  4934  may be transmitted as shown by step  5180  and stored in a specimen dispensing device  4902 , for example the information storage component  171  included in the control unit  17  of  FIG. 2 . The unique user data  4934  may be transmitted as shown by step  5190  and stored in a user person computing device  5020 , for example a computer, or a mobile phone. The unique user data  4934  may be transmitted as shown by step  5111  and stored in a database  5040  that is part of an internet cloud service, for example a remote server that hosts a database which can accept and provide data through internet connection, and being part of a user data cloud service, i.e. beauty cloud. 
     Now referring to  FIG. 52A  through  FIG. 52F , which illustrate examples of objective skin analysis  5101  and subjective skin analysis  5102 . 
       FIG. 52A  illustrates an example of skin analysis of the facial skin  5202  of a user  5201  by an imaging system  5203 . Imaging system  5203  can be a camera based system. Imaging system  5203  may capture photos or images of the skin  5202  under various lighting conditions, from various angles, with various distances from the user  5202 , with various resolutions, and with various optical or digital zoom of the different areas of skin  5202 . After images are captured, images may be further processed by pattern recognition software or hardware, for example a computing device or computer, to classify the skin features existing on user  5201  skin  5202  and also grade each of such features according to the size, location, distribution, strength, severity and overall appearance following a set of skin feature evaluation standards. Such image process and skin feature recognition and grading may also be regarded as part of the objective skin analysis  5101 , and quantitative skin feature grading  5103  of  FIG. 51 . Alternatively, the captured images may be reviewed and evaluated by a person, including, but not limited to, a skin care specialist, a skin dermatologist, or the user  5201 , and an estimation of existing skin features and their corresponding grades may be generated with the experience and expertise of the person. Such image evaluation and skin features estimation and grading may also be regarded as part of the subjective skin analysis  5102 , and qualitative skin feature grading  5104  of  FIG. 51 . 
       FIG. 52B  illustrates an example of skin analysis by radiation scanning. Radiation emitter  5205  emits radiation beams  5206  towards skin  5202  or user  5201 . Radiation detector  5204  detects the radiation signal from the radiation beams  5206  being reflected from the skin  5202  of user  5201 , whereas the radiation signal detected by the optical detector  5204  is converted into electrical signal for further electrical signal and data process. The radiation emitter  5205  may move in the directions that are substantially parallel to the skin  5202  surface to effectively produce scanning of the skin  5202  area radiation beams  5206 , whereas the radiation detector  5204  may move in substantially same speed and directions as the radiation emitter  5205 . The radiation beams  5206  emitted from radiation emitter  5205  may change its directions such that that radiation beams  5206  may effectively scan the areas of the skin  5202 , whereas the radiation detector  5204  may be stationary relative to the radiation emitter  5205  when directions of radiation beams  5206  changes. Reflected radiation signal detected by radiation detector  5204  and generated electrical signal by the radiation detector  5204  may be processed into information of one or more skin features with characteristics of the skin features including any of: feature existence, strength, severity, formation, composition, malignancy, depth into skin  5202 . During scanning of the radiation beams  5206  over the areas of skin  5202 , reflected radiation signal of  5206  detected by radiation detector  5204  may be also correlated with any of: the direction of the radiation beams  5206 , the spatial location of the radiation emitter  5205 , the spatial location of the radiation detector  5204 , relative to skin  5202 , to generate information of detected skin features including any of: size, location, distribution, and overall appearance. Radiation emitter  5206  radiation source may be any of: LED, laser, lamp, x-ray generator, and particle generator. Radiation beams  5206  may be any of: microwave, visible light, infrared light, ultra-violet light, x-ray, and particles of electron, alpha particle, ions, or molecules. Radiation detector  5204  may contain any of: CCD, CMOS sensor, photo diode, x-ray detector, electron detector, particle detector, ion detector, and molecule detector. Reflected signal from skin  5202  may also contain excited radiation from certain chemicals, elements, compositions that are contained within the skin features, or existing in the skin  5202 , by the excitation from incident radiation  5206 . The Electrical signal generated by radiation detector  5204  may be any of: strength of detected radiation signal, spectrum of detected radiation signal, spectrum of the blackbody radiation signal from the skin  5202 , wavelength of detected radiation signal, and existence of radiation signal at specific frequencies, for example excited radiation at certain frequency that is indication of existence of certain chemicals, elements or compositions. Such skin feature detection and grading may be regarded as part of the objective skin analysis  5101 , and quantitative skin feature grading  5103  of  FIG. 51 . 
       FIG. 52C  illustrates an example of skin analysis by skin feature mapping on skin  5202  of user  5201 . A skin mask  5207 , which is a facial mask as in  FIG. 52C , is disposed on top of the facial skin  5202  and later removed from the facial skin  5202 , as indicated by the two-ends arrow  5208 . Skin features, for example, fine lines, wrinkles, humps and sagging areas, brown spots, and other skin features that is topographically different than normal skin surrounding these feature, may have their locations, sizes, heights and numbers, transferred into the topographical features within the facial mask  5207 . Facial mask  5207  may then be brought into an optical examination system, for example, a microscope, an optical scanner, to be further analyzed on the transferred topographical features that correspond to the skin features of the skin  5202  of user  5201 . The results of such analysis may then be used for analysis steps  5101 ,  5102  and skin feature grading steps  5103  and  5104  of  FIG. 51 . Facial mask  5207  may also be brought into a topographical examination system, for example, a scanning needle based two-dimensional or three-dimensional scanning system that measures the topographical information of the surface of the mask  5207 , and converts that information into digital data. The digital data of such analysis may then be used for analysis steps  5101 ,  5102  and skin feature grading steps  5103  and  5104  of  FIG. 51 . A specific example is that the mask  5207  is a thin thickness facial mask, which is soft and compliant to the face of the user  5201 , for example, when the mask is hydrated. After the mask  5207  being disposed upon facial skin  5202  of user  5201  and tightly pressed against skin  5202  to eliminate all possible spaces between mask  5207  and skin  5202 , thus facial features on skin  5202  may transfer their physical properties to the mask, which is similar to a hard stencil transferring physical features to an overlaying soft substrate. When mask  5207  is removed from the skin  5202 , transferred physical properties of the skin features stay as topographic features of the mask  5207 . In one embodiment, face mask  5207  is removed after substantially losing partial or majority of the water content within the mask, whereas the topographic features transferred from skin features are hardened into the material of the mask  5207 . Afterwards, face mask  5207  may be analyzed by optical or topographical examination systems as described above. 
       FIG. 52D  illustrates an example of skin analysis by biological analysis, where a sampling tool  5209 , for example a cotton swab, is brought into contact with the skin  5202  of user  5201  at one or more locations on the skin  5202  to pick up surface chemicals, objects, or materials from skin  5202 . After the sampling tool  5209  is removed from skin  5202 , the sampling tool  5209  may be brought into a biological analysis system that is capable of measuring the existence and amount of chemicals, molecules, bacteria, skin debris, and other skin surface bearing materials deposited from the environment of the user  5201 . The data from such biological analysis may then be used for analysis steps  5101 ,  5102  and skin feature grading steps  5103  and  5104  of  FIG. 51 . 
       FIG. 52E  illustrates an example of skin analysis by user  5201  self-analysis aided by a computing device  5210 . Device  5210  may be any of: a computer, a mobile phone, and a tablet computing device. Device  5210  may have an imaging device  5211 , for example a camera. Imaging device  5211  may be built into the device  5210  as a component of the computing device  5210 . Imaging device  5211  may be externally attached to an electrical interface of the computing device  5210  through electrical wires. Imaging device  5211  may also be a device external to the computing device  5210  and communicating with computing device  5210  through wired or wireless data connections, for example through any of: internet, WIFI, Bluetooth, Infrared, or RF coupling through RF coupling coils. Imaging device  5211  may capture images of skin  5202  of user  5201  similarly as the imaging system  5203  captures images of skin  5202  in  FIG. 52A . Captured images by imaging device  5211  may be transferred to the computing device  5210  and may be saved in a database within the computing device  5210 . Afterwards, images may be further processed by pattern recognition software within computing device  5210  to classify the skin features existing on skin  5202  of user  5201  and may also grade each of such skin features according to the size, location, distribution, strength, severity and overall appearances following a set of skin feature evaluation standards. Such image process and skin feature recognition and grading may also be regarded as part of the quantitative skin feature grading  5103  of  FIG. 51 . Alternatively, the captured images may be reviewed and evaluated by a person, including any one of, but not limited to, a skin care specialist, a skin dermatologist, and the user  5201 , and an estimation of existing skin features and their corresponding grades may be generated with the experience and expertise of the person. Such image evaluation and skin features estimation and grading may also be regarded as part of the qualitative skin feature grading  5104  of  FIG. 51 . Said person that evaluates the images may be local as the user  5201  to evaluate the images on a display  5212 , or at a remote location where the images are transmitted to the said person through a data network, for example internet. Display  5212  may provide user  5201  and any person providing said evaluation the ability to view the captured images. Device  5210  may also provide a user interface to user  5201  or any person providing said evaluation which enables any of: displaying information to user  5201 , acquiring user  5201  input, for example display  5212  is also a touch screen and user  5201  may touch displayed information on display  5212  and provide information regarding skin  5202  or information regarding user  5201 that relates to skin care of skin  5202 . Information acquired from user  5201  by device  5210 , for example through user  5201  input via a touch screen display  5212  or another type of electronic input device like a mouse or a keyboard, may be used towards the subjective skin analysis  5102  and qualitative skin feature grading  5104  of  FIG. 51 . Further, such acquired information from user  5201  may be transmitted to a remote person, for example, a skin care specialist or a dermatologist, for an evaluation by the remote person, whereas the evaluation of said remote personal may be used towards the subjective skin analysis  5102 , qualitative skin feature grading  5104 , and unique user data  4934  of  FIG. 51 . 
       FIG. 52F  illustrates an example of skin analysis by visual evaluation, whereas the user  5201  provides self-evaluation with using a visualization tool  5214 , for example a mirror, to visually inspect skin  5202 . Visual evaluation as in  FIG. 52F  may also be conducted by another person, for example a skin care specialist, or a dermatologist, without using mirror  5214 . Results from the visual evaluation may be used towards the subjective skin analysis  5102  and qualitative skin feature grading  5104 , and unique user data  4934  of  FIG. 51   
     Now referring back to  FIG. 2 , where the at least one information processing component  172  is also located in and electronically coupled to the control unit  17 . It retrieves the first information stored in the information storage component  142  and the second information stored in the information storage component  171 , and then processes both the retrieved first and second information and provides commands and instructions to control the dispensing of specimen  19  from the dispenser  14 . 
     The electronic control unit  17  controls the dispensing of specimen  19  from dispenser  14 , through outlet  15 . The control unit  17  may also provide user interface, power supply and charging functions. Additionally, the electronic control unit  17  may send electrical signals to the specimen dispenser  14  or receives electrical signals from the specimen dispenser  14 , to achieve required skin treatment procedure through electrical interface  140  that electrically connects to the electrical contacts  141  on dispenser  14 . 
     The dispenser  14  may have any of the below features: (1) it can be removable, in other words, it may be taken out and installed back into the device  10  by the user; (2) the specimen  19  may be replenished within dispenser  14  by the user, or a health care professional, after depletion of the specimen during usage, i.e. dispenser  14  may be re-used; (3) dispenser  14  may be disposable and for one-time use only, where specimen  19  is pre-filled within the dispenser before usage; (4) the dispenser  14  can be configured as having multiple sub-dispensers containing same or different specimens such that the sub-dispensers can be individually selected to dispense contained specimen; (5) the dispenser  14  can be configured as a single dispenser with multiple specimen compartments that may contain same or different specimens, such that each compartment within the dispenser can be individually selected and dispense specimen; (6) the dispensing of the specimen  19  is fulfilled by a manually exerted or a pre-loaded force to the dispenser, upon which a pressure generation component that is part of the dispenser, for example a lead, a lever, a gauge, a cap, a piston, a spring, compressed air or a stretched pouch, forces the specimen  19  to flow out of the dispenser through the outlet  15 , where the control unit  17  controls the dispensing by limiting the amount of specimen being dispensed from one or more of the specimen containing compartments or sub-dispensers; (7) the dispensing of the specimen  19  is fulfilled by an electrically powered driving mechanism that is part of the dispenser and operated by the electrical interface  140  located within the device  10  body; (8) the dispensing of the specimen  19  is fulfilled by an electrically powered driving mechanism that is a part of the device and electrically controlled by the control unit  17 .

Dispenser  14  containing the specimen  19  therein, together with the information storage component  412  and electrical contacts  141  that are embedded in the dispenser  14 , may also be removed and detached from the device body  11  of dispensing device  10  as shown in  FIG. 15 . 
     Now referring to  FIG. 22A .  FIG. 22A  illustrates a specimen dispenser  14  of  FIG. 2 , also referred to as cartridge, in the form of a mechanically operated cartridge.  FIG. 22A  shows the cartridge  14  having an outside housing  2217 , an outlet  2252  and a piston  2218  that moves in the direction towards or away from the interior wall of the housing  2217  where the outlet  2252  is located. Specimen dispenser  14  and specimen outlet  2252  are similar as the cartridge  14  and outlet  15  of  FIG. 2 . Skin care specimen is stored in the space  2220  enclosed by the interior wall and the piston  2218 . When the piston  2218  moves towards the interior wall where the outlet  2252  is located and reduces the volume within the space  2220 , specimen is dispensed through outlet  2252  to outside the cartridge  14  due to pressure added to the specimen by the piston  2218 . Movement of the piston  2218  is mechanical, which can be realized through pushing and pulling force from a button-type or a roller-type leverage structures existing externally on the device body  11  of  FIG. 2 , and thus the specimen dispensing can be manually controlled by the user. Alternatively, the pushing and pulling force can be applied through electric motor component residing within the device body  11  of  FIG. 2 , and thus the specimen dispensing can be operated by an electrical-switch-type or a touch-sensor-type electronic interface located externally on the device body  11  of  FIG. 2 . 
       FIG. 22B  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a cartridge having a first type preloaded dispensing force and specimen flow gate. It is similar to  FIG. 22A , but the pushing force is applied by embedded loading force, as exampled by the spring like structure  2219  in  FIG. 22B . The loading force can be applied from either side of the piston  2218 , where  FIG. 22B  is only one of many variations. In addition, the loading force can be implemented as, including but not limited to, spring, rubber cushion, rubber band or compressed air. The loading force applies a pressure on the specimen within the space  2220 , and the specimen can be dispensed through outlet  2252  automatically as soon as the outlet  252  is set to an open mode. To control and limit flow of specimen, a switch structure such as a valve  2221 , also referred to as specimen flow gate, is coupled to the outlet  2252 , which is able to close and open the flow path of specimen through outlet  252 . The valve  2221  can be a slit valve, a one-way valve, or a double-way valve. Operation of the valve  2221  can be realized through a button-type or a roller-type leverage structures existing externally on the device body  11  of  FIG. 2 , and the specimen dispensing can be operated manually. Alternatively, valve  2221  can be operated through an electric motor component residing within the device body  11  of  FIG. 2 , and thus the specimen can be operated by an electrical-switch-type or a touch-sensor-type electronic interface existing externally on the device body  11  of  FIG. 2 . Operation of the valve  2221  can be realized as a pressure operation valve similar to the valve  2325  through valve switch  2324  of  FIG. 23B , and can be operated manually. Alternatively, valve  2221  can be operated through an electrically driven switch that user operates through an electrical interface. 
       FIG. 22C  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a cartridge having a second type preloaded dispensing force and specimen flow gate. It is similar to  FIG. 22B , but replacing the piston and loading structure with a simple self-contracting pouch  2222  existing within the enclosed housing  2217 . The specimen is contained in the internal space  2220  of the pouch  2222 . The self-contracting pouch  2222  can be, but not limited to, a dilated rubber pocket. The self-contracting force of the pouch  2222  produces enough pressure to dispense the specimen when the valve  2221 , also referred to as specimen flow gate, opens up the flow through the outlet  2252 . Alternatively, the pouch  2222  provides containment as a bladder, while the space  2229  may be filled with pressurized air or gas, which is capable of shrinking the volume of the pouch  2222  and squeezing out the specimen within  2220  through the outlet  2252  when the flow gate  2221  is turned on. Flow gate  2221  of  FIG. 22C  is same as flow gate  2221  in  FIG. 22B . 
       FIG. 22D  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a mechanically operated cartridge having a specimen flow gate.  FIG. 22D  is a variation of  FIG. 22A  with a valve  2221 , also referred to as specimen flow gate, coupled to the outlet  2252 . The valve  2221  can be operated simultaneously with the piston  2218  to produce more precise specimen flow through the outlet  2252 . Operation of valve  2221  can be achieved through the same mechanical or electronic interface that user uses to operate piston  2218 . Flow gate  2221  of  FIG. 22D  is same as flow gate  2221  in  FIG. 22B . 
       FIG. 23A  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a cartridge having a propellant  2323  driven piston  2318  and a specimen flow gate  2321 .  FIG. 23A  shows the cartridge  14  having an outside housing  2317 , a specimen outlet  2352  and a piston  2318  that moves in the direction towards or away from the interior wall of the housing  2317  where the outlet  2352  is located. Specimen dispenser  14  and specimen outlet  2352  are similar as the cartridge  14  and outlet  15  of  FIG. 2 . Skin care specimen  19  of  FIG. 2  is stored in the space  2320  enclosed by the interior wall of the housing  2317 , and the piston  2318  surface facing the outlet  2352 . When the piston  2318  moves towards the interior wall where the outlet  2352  is located, and reduces the volume within the space  2320 , specimen is dispensed through outlet  2352  to outside the cartridge  14  due to pressure added to the specimen by the piston  2318 . In  FIG. 23A , movement of the piston  2218  towards the outlet  2352  is driven by a pre-filled pressurized propellant  2323 , for example a compressed gas, which fills the space defined by the interior wall of the housing  2317 , and the piston  2318  surface facing away from the outlet  2352 . During a specimen dispensing operation, flow gate  2321  opens up and allows specimen within space  2320  to flow outside of the cartridge  14  through outlet  2352 . As the specimen flows outside of cartridge, specimen pressure reduces in the space  2320  and piston  2318  further moves towards the interior wall of the housing  2317  where the outlet  2352  is located due to a higher pressure from the pressurized propellant  2323 . If flow gate  2321  continuously opens, the piston  2318  will continue moving until reaching the interior wall of the housing  2317  where the outlet  2352  is located and finish dispensing specimen from space  2320 . When the flow gate  2321  shuts off, with specimen still remaining in space  2320 , the specimen space  2320  reduces to the size where the pressure in the specimen space  2320  equals pressure in the propellant  2323 , and piston  2318  stops moving. Turn on and shut off operations of the flow gate  2321  may be performed through a mechanical switch operated by user manually, or by an electrically driven switch that user operates through an electrical interface. 
       FIG. 23B  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a cartridge having a propellant  2323  driven piston  2318  and a flow valve  2325  controlled by externally applied pressure. Specimen dispenser  14  and specimen outlet  2352  are similar as the cartridge  14  and outlet  15  of  FIG. 2 .  FIG. 23B  is a variation of  FIG. 23A  and operates similarly as  FIG. 23A , with the exception that the flow gate  2321  being replaced by a flow valve  2325 . Flow valve  2325  is in shut off state by default. An externally attached valve switch  2324  is used to turn on the flow valve  2325  and allow the specimen to be dispensed from the space  2320 . Valve switch  2324  is mechanically operated, whereas an externally applied pressure on valve switch  2324  may produce a mechanical response from the flow valve  2325  and causes the flow valve  2325  to turn on. After the externally applied pressure is removed from the valve switch  2324 , flow valve  2325  will return to shut off state. Outlet  2352  pass through both valve switch  2324  and flow valve  2325  and reaches into the specimen space  2320 . 
       FIG. 23C  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a cartridge having an airless pump  2335  and a piston  2318 .  FIG. 23C  shows a cartridge  14  structure similar as in  FIG. 23B , except the flow valve  2325  and valve switch  2324  of  FIG. 23B  are replaced by an airless pump  2335  and pump lever  2334  in  FIG. 23C . Also, the propellant  2323  of  FIG. 23B  is replaced by air in space  2329  in  FIG. 23C , whereas the air is filled in space  2329  from outside the cartridge  14  through an air inlet  2326  in the wall of the housing  2317 . During operation, airless pump  2335  is in shut off state by default, until an external pressure is applied on the pump lever  2334 , which further operates the airless pump  2335  to extract specimen from the space  2320  and dispenses the extracted specimen through the outlet  2352  to outside the cartridge  14 . A typical airless pump  2335  will output a certain amount of specimen upon every pressure event on the pump lever  2334 , for example a pressing of the pump lever  2334  towards inside the cartridge  14  will produce a given amount of specimen out of space  2320 . After specimen is dispensed from the space  2320 , pressure within  2320  reduces below air pressure within air of space  2329  and allows the piston  2318  to move towards the interior wall where the outlet  2352  is located, and reduces the volume within the space  2320 . More air flows from outside the cartridge  14  through the air inlet  2326  and fills in cartridge  14  space  2329 . 
       FIG. 23D  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a cartridge having an airless pump and a specimen containment pouch. Cartridge  14  of  FIG. 23D  operates similarly as in  FIG. 23C , except that the piston  2318  of  FIG. 23C  is replaced by a pouch  2328  in  FIG. 23D , and space  2320  is enclosed within the pouch  2328  as in  FIG. 23D . During a dispensing operation, where an external pressure is applied on the pump lever  2334 , the airless pump  2335  extracts specimen from the space  2320  and dispenses the extracted specimen through the outlet  2352  to outside the cartridge  14 . After specimen is dispensed from the space  2320 , pressure within  2320  reduces below air pressure within air  2329 , and causing the pouch  2328  to contract due to air pressure of space  2329  being higher, and reduces the volume within the space  2320 . Then, more air flows from outside through the air inlet  2326  and fill in space  2329 . 
       FIG. 24A  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a cartridge having a pressured air  2423  driven piston  2418 , an air pump  2430  and a specimen flow gate  2421 . Cartridge  14  of  FIG. 24A  operates substantially similar to cartridge  14  of FIG.  23 A, except that the propellant  2323  of  FIG. 23A  is replaced by a pressured air  2423 . An air inlet  2426  existing in the wall of the housing  2417  allows air pump  2430  to inject air into the cartridge  14  space between the piston  2418  surface, which opposes space  2420  that contains specimen, and the housing  2417 , to produce a pressured air  2423 . Pressured air  2423  functions substantially similar to the propellant  2323  in  FIG. 23A . Piston  2418  and flow gate  2421  also function similarly as the piston  2318  and flow gate  2321  in  FIG. 23A   
       FIG. 24B  illustrates a specimen dispenser  14 , also referred to as cartridge, in the form of a cartridge having a pressured air  2423  driven piston  2418  and an air pump  2430 . Cartridge  14  of  FIG. 24B  has similar structure as cartridge  14  of  FIG. 24A , except that the flow gate  2421  of  FIG. 24A  is removed from  FIG. 24B . During operation, when no air is injected into the cartridge  14  by the air pump  2430  to cause the pressure of the air  2423  to increase, piston  2418  does not move and specimen in space  2420  does not flow outside of the cartridge  14  through the outlet  2452 . When air pump  2430  injects air into cartridge  14  and increase pressure in air  2423 , due to higher air pressure of  2423  than specimen pressure in space  2420 , piston  2418  moves towards the interior wall of the housing  2417  where the outlet  2452  is located and forces specimen contained in space  2420  to dispense and flow out of the cartridge  14  through outlet  2452 . When air pump  2430  stops injecting air into the cartridge  14 , the piston will continue moving and specimen being dispensed from space  2420  until pressure in air  2423  reduces to the level that is same as the pressure in specimen within space  2420 . In the case where air injection from air pump  2430  continues, specimen in  2420  may be depleted and the piston stops moving when reaching the interior wall of the housing  2317  where the outlet  2352  is located. 
     For the specimen outlets  2252 ,  2352  and  2452  in the specimen dispensers as described in  FIG. 22A  through  FIG. 24B , it is desirable to be able to dispense the specimen through the outlets, while also being able to eliminate back-flow of specimen into the cartridges through the outlets, and being able to avoid contaminants entering the cartridges through the outlets.  FIG. 25A  through  FIG. 28D  illustrate the local cross-section views of any one of the specimen outlets  2252 ,  2352  and  2452 , and any specimen outlet of any specimen dispenser or any specimen dispenser holder as described in any prior or later figures or embodiment of this invention, which also includes but not limited to,  FIG. 31A  through  FIG. 48B , whereas the cross-section is along center plane that passes through a center line of the outlet and the center plane divides the outlet into two substantially equivalent portions.

       FIG. 31A  illustrates cross-sectional view of specimen dispenser  3001  of  FIG. 30  with a cross-section plane along a center line  300  as in  FIG. 30  that divides the cartridge  3001  of  FIG. 30  into substantially equal halves, whereas specimen dispenser  3001  of  FIG. 30  having surface electrical contacts  3105 , embedded electrical or mechanical components  3106 ,  3107 ,  3110 , and an embedded electrically operated specimen driver  3104 . In  FIG. 31A , specimen dispenser is formed by an enclosing housing  3101 . A specimen driver  3104  is enclosed in the housing  3101 . Specimen  3102  is also enclosed within the housing  3101  by the wall of the housing  3101  and a piston  3103 , which is also enclosed in the housing  3101 . Specimen driver  3104  is preferred to be positioned against an internal wall of the housing  3101 . A propellant  3113  exists in between the specimen driver  3104  and the piston  3103 . The specimen driver  3104  is capable of increasing the pressure in the propellant  3113 , which in turn produces pressure and force on piston  3103  that tends to move piston  3103  inside the housing  3101  in the direction towards the specimen outlet  3109 . Specimen outlet  3109  is located in the housing  3101  wall that is orthogonal to the piston  3103  moving directions. The outlet  3109  contains a flow gate  3107 , which can open or shut off the specimen  3102  flow towards outside the housing  3101  through the outlet  3109 . In a dispensing operation, flow gate  3107  opens, and the pressurized propellant  3113  forces piston  3103  to move in direction towards the outlet  3109  to increase space occupied by propellant  3113  and reduces pressure in the propellant  3113 , whereas the piston  3103  movement forces the specimen  3102  to flow outside of the housing  3102  through the outlet  3109 . When flow gate  3107  shuts off, specimen  3102  is contained within the housing  3101  and pressure in the propellant  3113  does not produce a movement of the piston  3103  due to specimen  3102  is blocked by the flow gate  3107  and pressure built up in the specimen  3102  equals pressure in the propellant  3113 . The specimen driver  3104  may increase the pressure within propellant  3113  by releasing more propellant material into the space occupied by propellant  3113 . In such case, the specimen driver  3104  may comprise a container that contains compressed propellant  3113  material, for example compressed liquid gas or air, and specimen driver  3104  may release the propellant  3113  material from the compressed form into the space of the housing  3101  occupied by the propellant  3113 . The specimen driver  3104  may also increase the pressure within propellant  3113  by pumping air from outside of the housing  3101  into the space occupied by the propellant  3113 . In such case, an air intake  3120  may exists in the housing wall that specimen driver  3104  resides, whereas the specimen driver  3104  draws air from outside of the housing  3101  through the air intake  3120  into the housing  3101 , and then pumps the drawn air into the propellant  3113  space, whereas propellant  3113  is also air, to increase the pressure in propellant  3113 .  FIG. 31A  also shows that the dispenser housing  3101  has surface electrical contacts  3105 , whereas electrical connections  3108  may connect the electrical contacts  3105  to one or more of: the specimen driver  3104 , the embedded electronic component  3106 , a specimen remaining volume sensor  3110 , and the flow gate  3107 . As illustrated in  FIG. 31A , through the electrical contacts  3105  and the connections  3108 , one or more of the components, including but not limited to: the specimen driver  3104 , the embedded electronic component  3106 , a specimen remaining volume sensor  3110 , and the flow gate  3107 , may be controlled electrically by an electrical control unit, for example control unit  17  of  FIG. 14  and  FIG. 15 , that is external to the housing  3101 . The embedded electronic component  3106  may be any of: a control unit that controls specimen driver  3104 , the specimen remaining volume sensor  3110 , or the flow gate  3107  through circuits embedded in the housing  3101 ; a logic unit; a data processer; a CPU; a memory; a data communication device including WIFI chip, RFID chip and Bluetooth chip; an information storage device that is similar to the same component  142  as in  FIG. 14  and  FIG. 15 . 
       FIG. 31B  illustrates cross-sectional view of a specimen dispenser  3001  of  FIG. 30  with a cross-section plane along a center line  300  as in  FIG. 30  that divides the cartridge  3001  of  FIG. 30  into substantially equal halves, whereas specimen dispenser  3001  of  FIG. 30  having surface electrical contacts  3105 , embedded electrical or mechanical components  3106 ,  3107 ,  3110 , and an exposed electrically operated specimen driver  3104 .

The specimen driver  3104  of  FIG. 31B  is exposed to air outside of housing  3101  and does not require an air intake  3120  as in  FIG. 31A  to pump air into the propellant  3113  of  FIG. 31B . The specimen driver  3104  of  FIG. 31B  may be externally inserted into the housing  3101  opening during assembly of the dispenser, rather than requiring an assembly process to fully enclose the specimen driver  3104  by the dispenser housing  3101  as in  FIG. 31A . 
       FIG. 31C  illustrates cross-sectional view of a specimen dispenser  3001  of  FIG. 30  with a cross-section plane along a center line  300  as in  FIG. 30  that divides the cartridge  3001  of  FIG. 30  into substantially equal halves, whereas specimen dispenser  3001  of  FIG. 30  having surface electrical contacts  3105 , embedded electrical or mechanical components  3106 ,  3107 ,  3110 , and an embedded electrical-mechanical specimen driver  3114 . In  FIG. 31C , specimen dispenser is formed by an enclosing housing  3101 . A specimen electrical-mechanical driver  3114  is enclosed in the housing  3101 . Specimen  3102  is also enclosed within the housing  3101  by the wall of the housing  3101  and a piston  3103 , which is also enclosed in the housing  3101 . Specimen driver  3114  is preferred to be positioned against an internal wall of the housing  3101 . A mechanical pusher  3123  exists in between the specimen driver  3114  and the piston  3103  and in direct contact with the piston  3103 , whereas the length or size of the pusher  3123  may increase during a dispensing operation where such increase of length or size of the pusher  3123  is produced by the specimen driver  3114 . 
     Now referring to  FIG. 83A , which shows a first example of the pusher  3123  of  FIG. 31C . Pusher  8302  and piston  8301  of  FIG. 83A  are same as the pusher  3123  and piston  3103  of FIG.  31 C. The pusher  8302  of  FIG. 83A  is a threaded rod with threads  8312  that occupies a substantial length of the pusher rod  8302 , making the pusher  8302  being similar to a screw, whereas the specimen driver  3114  of  FIG. 31C  couples to the threads  8312  of pusher  8302  through an threaded rotary motor  8303 , such that the motor  8303  threads match to the threads  8312  of the pusher  8302 . The specimen driver  3114  of  FIG. 31C  produces a rotary motion of the motor  8303  in the direction of  8331  and threads of motor  8303  push the threads  8312  of pusher  8302  to produce a downward movement of the pusher  8304  in  8304  direction which in turn pushes the piston  8301  in direction  8304 , which is towards the outlet  3109  as in  FIG. 31C . 
     Now referring to  FIG. 83B , which shows a second example of the pusher  3123  of  FIG. 31C . Pusher  8302  and piston  8301  of  FIG. 83B  are same as the pusher  3123  and piston  3103  of  FIG. 31C . The pusher  8302  of  FIG. 83B  may be a rod, whereas the specimen driver  3114  of  FIG. 83B  couples to the rod pusher  8302  through one or more rotary wheels  8305 , such that the wheels  8305  rotation initiated by the specimen driver  3114  of  FIG. 31C  in the directions  8351  of  FIG. 83B  produces a downward movement of the pusher rod  8302  in the direction  8304  due to the friction force between the wheels  8305  surface pushing against the rod  8302  surface, which in turn pushes piston  8301  in direction  8304 , which is towards the outlet  3109  as in  FIG. 31C . Pusher  8302  may also have threads or gear teeth on its surface, whereas the threads or gear teeth of the pusher  8302  surface may couple to threads or gear teeth that may exist on the surface of the wheels  8305 , which may be gear wheels. 
     Now referring to  FIG. 83C , which shows a third example of the pusher  3123  of  FIG. 31C . Pusher  8302  and piston  8301  of  FIG. 83C  are same as the pusher  3123  and piston  3103  of  FIG. 31C . The pusher  8302  of  FIG. 83C  may be a metal rod, or a rod made of partially or entirely of permanent magnet, whereas the specimen driver  3114  of  FIG. 31C  electromagnetically couples to the rod pusher  8302  through one or more sets of electrical coils or voice coils  8306 , for example the rod  8302  may pass through a center clearance of the coils  8306  as shown in  FIG. 83C . When an electric current  8361  is applied by the specimen driver  3114  of  FIG. 31C , and the current  8361  passes through one or more of the electrical coils  8306 , the current  8361  within the coils  8306  produces magnetic field which through electromagnetic interactions with the metal or permanent magnet rod pusher  8302  causes a downward movement of the piston  8301  in direction  8304 , which is towards the outlet  3109  as in  FIG. 31C . Pusher  8302  of  FIG. 83C  may be in other shapes, for example ring, block or tube, that electromagnetically couple to the coils  8306 . 
     Now referring to  FIG. 83D , which shows a fourth example of the pusher  3123  of  FIG. 31C . Pusher  8302  and piston  8301  of  FIG. 83D  are same as the pusher  3123  and piston  3103  of  FIG. 31C . The pusher  8302  of  FIG. 83D  is a cross-frame structure that has two of more hinged arms joining at a hinge  8320  that is fixed on the surface of the piston  8301 . The pusher  8302  has least two top moving sections  8322 , each of the top moving sections is connected to a hinged arm at a joint hinge  8321 . The top moving sections  8322  are coupled to a threaded rod  8323 . Specimen driver  3114  of  FIG. 31C  causes a rotation of the threaded rod  8323  in direction  8325  along the rod  8323  center line  8324 , such rotation produces a movement of each of the top sections  8322  moving in directions  8326  and reduces the spacing between the top sections  8322  on the rod  8323 . The closing up of spacing of top sections  8322 , through the hinges  8321  and  8320 , causes the arms of the pusher  8302  to extend in vertical direction in  FIG. 83D  and causes a downwards movement of the piston  8301  in direction  8304 , which is towards the outlet  3109  as in  FIG. 31C . 
     Now referring back to  FIG. 31C , specimen outlet  3109  is located in the housing  3101  wall that is orthogonal to the piston  3103  moving directions. The outlet  3109  contains a flow gate  3107 , which can open and shut off the specimen  3102  flow towards outside the housing  3101  through the outlet  3109 . In a dispensing operation, flow gate  3107  opens, and the pusher  3123  forces piston  3103  to move in direction towards the outlet  3109 , whereas the piston  3103  movement forces the specimen  3102  to flow outside of the housing  3101  through the outlet  3109 . When flow gate  3107  shuts off, specimen  3102  is contained within the housing  3101  and pusher  3123  does not produce a movement of the piston  3103  due to specimen  3102  is blocked by the flow gate  3107 .  FIG. 31C  also shows that the dispenser housing  3101  has surface electrical contacts  3105 , whereas electrical connections  3108  may connect the electrical contacts  3105  to one or more of: the specimen driver  3114 , the embedded electronic component  3106 , a specimen remaining volume sensor  3110 , and the flow gate  3107 . As illustrated in  FIG. 31C , through the electrical contacts  3105  and the connections  3108 , one or more of the components, including but not limited to: the specimen driver  3114 , the embedded electronic component  3106 , a specimen remaining volume sensor  3110 , and the flow gate  3107 , may be controlled electrically by an electrical control unit, for example control unit  17  in  FIG. 14  and  FIG. 15 , that is external to the housing  3101 . The embedded electronic component  3106  may be any of: a control unit that controls specimen driver  3114  or the specimen remaining volume sensor  3110  or the flow gate  3107  through circuits embedded in the housing  3101 , a logic unit, a data processer, a CPU, a memory, a data communication device including WIFI chip, RFID chip and Bluetooth chip, an information storage device that is similar to the same component  142  as in  FIG. 14  and  FIG. 15   
       FIG. 31D  illustrates cross-sectional view of a specimen dispenser  3001  of  FIG. 30  with a cross-section plane along a center line  300  as in  FIG. 30  that divides the cartridge  3001  of  FIG. 30  into substantially equal halves, whereas specimen dispenser  3001  of  FIG. 30  having surface electrical contacts  3105 , embedded electrical or mechanical components  3106 ,  3107 ,  3110 , and an exposed attached electrical-mechanical specimen driver  3114 . Dispenser of  FIG. 31D  is substantially similar in both structure and function of components as the dispenser of  FIG. 31C  with components of  FIG. 31D  being functioning identically as the components having same numeral numbers as in  FIG. 31C , with the only exception that the housing  3101  is not fully closed and with an opening where the specimen driver  3114  is located therein. The specimen driver  3114  of  FIG. 31D  is exposed to air outside of housing  3101 , and may be externally inserted into the housing  3101  opening during assembly of the dispenser, rather than requiring an assembly process to fully enclose the specimen driver  3114  by the dispenser housing  3101  as in  FIG. 31C . 
       FIG. 32A  illustrates cross-sectional view of a specimen dispenser  3001  of  FIG. 30  with a cross-section plane along a center line  300  as in  FIG. 30  hat divides the cartridge  3001  of  FIG. 30  into substantially equal halves, whereas specimen dispenser  3001  of  FIG. 30  having surface electrical contacts  3205 , embedded electrical or mechanical components  3206 ,  3207 ,  3210 , and an externally attached mechanical specimen driver  3204 . In  FIG. 32A , specimen dispenser is formed by an closed housing  3201 . A specimen mechanical driver  3204  is externally attached to the housing  3201 . Specimen  3202  is enclosed within the housing  3201  by the wall of the housing  3201  and a piston  3203 , which is also enclosed in the housing  3201 . Specimen driver  3204  is coupled to a mechanical pusher  3213  that extends from the specimen driver  3204  and into the housing  3201  to be in direct contact with the piston  3203 , whereas the length or size of the pusher  3223  may increase during a dispensing operation where such increase of length or size of the pusher  3223  is produced by the specimen driver  3204 . Pusher  3213  and specimen driver  3204  function substantially similar to pusher  3123  and specimen driver  3114  of  FIG. 31C . Examples of pusher  3213  function to push the piston  3203  can also be found in  FIG. 92A  through  FIG. 92D , where pushers  9202 , pistons  9201  are same as pusher  3213  and piston  3203  of  FIG. 32A . The mechanical specimen driver  3204  may be manually operated by the user of the device  3003  as in  FIG. 30  to produce mechanical movements, for example movement  9231 ,  9251 ,  9225  as shown in  FIG. 92A ,  FIG. 92B  and  FIG. 92D . The mechanical specimen driver  3204  may also be electrically operated by a control unit, for example control unit  17  of  FIG. 14  and  FIG. 15 , that is enclosed in the device body  3003  of  FIG. 30 , through electrical connections, where the control unit produces mechanical movements, for example movement  9231 ,  9251 ,  9225  as shown in  FIG. 92A ,  FIG. 92B  and  FIG. 92D , or electrical signal, for example current  9261  as shown in  FIG. 92C . The mechanical specimen driver  3204  as in  FIG. 32A  may be part of the device body  3003  of  FIG. 30  that attaches to the housing  3201  as in  FIG. 32A  of dispenser  3001  of  FIG. 30  externally after cartridge dispenser  3001  is inserted into the slot  3004  as illustrated in  FIG. 30 . 
     In  FIG. 32A , specimen outlet  3209  is located in the housing  3201  wall that is orthogonal to the piston  3203  moving directions. The outlet  3209  contains a flow gate  3207 , which can open and shut off the specimen  3202  flow towards outside the housing  3201  through the outlet  3209 . In a dispensing operation, flow gate  3207  opens, and the pusher  3213  forces piston  3203  to move in direction towards the outlet  3209 , whereas the piston  3203  movement forces the specimen  3202  to flow outside of the housing  3201  through the outlet  3209 . When flow gate  3207  shuts off, specimen  3202  is contained within the housing  3201  and pusher  3213  does not produce a movement of the piston  3203  due to specimen  3202  is blocked by the flow gate  3207 .  FIG. 32A  also shows that the dispenser housing  3201  has surface electrical contacts  3205 , whereas electrical connections  3208  may connect the electrical contacts  3205  to one or more of: the embedded electronic component  3206 , a specimen remaining volume sensor  3210 , and the flow gate  3207 . As illustrated in  FIG. 32A , through the electrical contacts  3205  and the connections  3208 , one or more of the components, including but not limited to: the embedded electronic component  3206 , a specimen remaining volume sensor  3210 , and the flow gate  3207 , may be controlled electrically by an electrical control unit, for example control unit  17  in  FIG. 14  and  FIG. 15 , that is external to the housing  3201 . The embedded electronic component  3206  may be any of: a control unit that controls the specimen remaining volume sensor  3210  or the flow gate  3207  through circuits embedded in the housing  3201 , a logic unit, a data processer, a CPU, a memory, a data communication device including WIFI chip, RFID chip and Bluetooth chip, an information storage device that is similar to the same component  142  as in  FIG. 14  and  FIG. 15 . 
       FIG. 32B  illustrates cross-sectional view of a specimen dispenser  3001  of  FIG. 30  with a cross-section plane along a center line  300  that divides the cartridge  3001  of  FIG. 30  into substantially equal halves, whereas specimen dispenser  3001  of  FIG. 30  having surface electrical contacts  3205 , embedded electrical or mechanical components  3206 ,  3207 ,  3210 , and an externally attached air pump specimen driver  3224 . Dispenser of  FIG. 32B  is substantially similar in the structure and function of components as the dispenser of  FIG. 32A  with components of  FIG. 32B  being functioning identically as the components having same numeral numbers as in  FIG. 32A , with the exception that the specimen driver  3224  drives the piston  3203  moving downwards in  FIG. 32B  and forces dispensing of specimen  3202  by injecting air  3214  into the housing  3201  through an air intake  3223  located next to the specimen driver  3224  in the housing  3201 , rather than by a mechanical pusher  3213  as in  FIG. 32A . The specimen driver  3224  of  FIG. 32B  injects air into the housing  3201  space between the piston  3203  and housing  3201  occupied by air  3214  and increases the pressure in air  3214 . When flow gate  3207  of  FIG. 32B  opens, pressure in air  3214  produces a movement of piston  3203  towards outlet  3209  and forces specimen  3202  to be dispensed out of the housing  3201  through the outlet  3209 . 
       FIG. 32C  illustrates cross-sectional view of a specimen dispenser  3001  of  FIG. 30  with a cross-section plane along a center line  300  that divides the cartridge  3001  of  FIG. 30  into substantially equal halves, whereas specimen dispenser  3001  of  FIG. 30  having surface electrical contacts  3205 , embedded electrical or mechanical components  3206 ,  3207 , 3210 , and specimen driving by internal propellant  3214 . Dispenser of  FIG. 32C  is substantially similar in the structure and function of components as the dispenser of  FIG. 32B  with components of  FIG. 32C  being functioning identically as the components having same numeral numbers as in  FIG. 32B , with the exception that the specimen driver  3224  and air intake  3223  as in  FIG. 32B  are removed and replaced by an internal propellant  3214  as illustrated in  FIG. 32C . The propellant  3214  exists in the space between the piston  3203  and housing  3201  and is pressurized. The propellant  3214  may be made of compressed air or other types of gas, and produces a constantly applied pressure on the piston  3203 . When flow gate  3207  of  FIG. 32C  opens, pressure from propellant  3214  on the piston  3203  produces a movement of piston  3203  towards outlet  3209  and forces specimen  3202  to be dispensed out of the housing  3201  through the outlet  3209 . 
       FIG. 32D  illustrates cross-sectional view of a specimen dispenser  3001  of  FIG. 30  with a cross-section plane along a center line  300  that divides the cartridge  3001  of  FIG. 30  into substantially equal halves, whereas specimen dispenser  3001  of  FIG. 30  having surface electrical contacts  3205 , embedded electrical or mechanical components  3206 ,  3207 ,  3210 ,  3211  and specimen driving by a pump  3211  located in proximity to the dispenser outlet  3209 . In  FIG. 32D , specimen dispenser is formed by an closed housing  3201 . A specimen pump  3211  is embedded in the housing  3201  and in close proximity to the outlet  3209 . Specimen  3202  is enclosed within the housing  3201  by the wall of the housing  3201  and a piston  3203 , which is also enclosed in the housing  3201 . An air chamber  3215  existing in between the space enclosed by the wall of the housing  3201  and the side of the piston  3203  opposing the specimen  3202 , and the air chamber  3215  is connected to external air through an air intake  3220  located in the housing  3201 . Specimen pump  3211  is capable of pumping specimen  3202  out of the housing  3201  through the outlet  3209  when the flow gate  3207  is open. The specimen pump  3211  may be operated electrically through electrical connection  3208  that connects the specimen pump  3211  to the surface pad  3205  and consequently a control unit located in the device body  3003  of  FIG. 30 . Alternatively, specimen pump  3211  may be operated by electrical components embedded in housing  3201 , for example a control unit  3206 , through electrical connections embedded in the housing  3201 . When specimen  3202  is pumped out of the housing  3201  by the specimen pump  3211  through the outlet  3209 , the decreased pressure in specimen  3202  causes the piston  3203  to move in the direction towards the outlet  3209  due to the air pressure in air chamber  3215  being higher than in the specimen  3202 , and more external air enters the air chamber  3215  through the air intake  3220 . 
     Now referring to  FIG. 33A  through  FIG. 33F . The specimen conduit  3301  of  FIG. 33A  through  FIG. 33F  connects the specimen  3202  of  FIG. 32D  from inside the housing  3201  to the outlet  3209  as in  FIG. 32D . Outlet  3309  of  FIG. 33A  through  FIG. 33F  is same as outlet  3209  of  FIG. 32D . 
       FIG. 33A  illustrates an example of specimen pump  3211  of  FIG. 32D , which includes a thermal excitation circuits  3331  around a specimen conduit  3301 . Thermal excitation circuits  3331  may be positioned in close proximity to, or directly in contact with, the conduit  3301 . Electric current may be applied through the circuits  3331  via the electrical connections  3208  as in  FIG. 32D  to generate local heating of the conduit  3301  and the specimen  3302  contained within the conduit. Heating by the thermal excitation circuits  3331  may be through direct heat generation of the current flowing through the circuits  3331 , whereas the circuits  3331  function as heating coil and said current lowing through the circuits  3331 may be a DC current. Heating by the thermal excitation circuits  3331  may also be from a low frequency AC current with AC frequency less than 100 Megahertz (MHz). In such case, conduit  3301  experiences heat radiation from the circuits  3331  or heat transfer through direct contact with the circuits  3331 , while specimen  3302  is heated by heat transfer from the conduit  3301  through direct contact. Alternatively, heating by the thermal excitation circuits  3331  can be through an AC current flowing through the circuits  3331  at an RF frequency larger than 100 MHz, whereas the RF frequency AC current flowing through the circuits  3331  generates microwave that heat certain molecules of the specimen  3302  directly through a process of dielectric heating, for example the AC frequency is 2.45 Gigahertz (GHz) or 915 MHz and molecules in specimen  3302  being heated are any of: water, fat, and other substances that absorb energy from the microwave. In such case, the thermal excitation circuits  3331  may heat the specimen  3302  contained in the conduit  3301  directly through microwave generated by the circuits  3331 , and conduit  3301  may be less heated or affected by the microwave than the specimen  3302 . When the specimen  3302  of  FIG. 33A  is heated locally within the conduit  3301 , the material of the specimen  3302  contained within the conduit  3301  may increase volume and forces increased volume of the specimen  3302  to move outside the conduit  3301  and through the outlet  3309 , and thus specimen  3302  is dispensed from the conduit  3301  through the outlet  3309 . After specimen  3302  dispensing, the heating may stop to allow conduit  3301  and the specimen  3302  to cool down, and to allow more specimen to replenish the space within the conduit  3301  for the next dispensing event of specimen  3302  by heating. 
       FIG. 33B  illustrates an example of specimen pump  3211  of  FIG. 32D , with specimen being dispensed by heating from circuits  3331  on a specimen conduit  3301  and specimen contained therein.  FIG. 33B  shows an alternative method of dispensing specimen  3302  of  FIG. 33A  through heating by the circuits  3331 , whereas the electric current flowing through the circuits  3331  causes a local heating of the conduit  3301 . Material of the conduit  3301  of  FIG. 33B  has the property of thermal expansion, as shown by the  3332  in  FIG. 33B , during heating, and thus the local heating of the conduit  3301  by the circuit  3331  produces a narrowed conduit  3301  internal width and a smaller conduit  3301  volume that holds the specimen  3302 . Due to this reduced internal volume of conduit  3301 , specimen  3302  is forced, or squeezed, to flow out of the conduit  3301  and through the outlet  3309  in direction of  3333 , and thus specimen  3302  is dispensed from the conduit  3301  through the outlet  3309 . After specimen  3302  dispensing, the heating may stop to allow conduit  3301  to cool down, and to allow more specimen to replenish the space within the conduit  3301  for the next dispensing event of specimen  3302  by heating. 
       FIG. 33C  illustrates an example of specimen pump  3211  of  FIG. 32D , including a piezo element  3303  attached to a specimen conduit  3301  and specimen  3302  contained therein. At least two electrical connections  3304 , which are similar as electrical connections  3208  of  FIG. 32D , are electrically coupled to the at least two electrodes of the piezo element  3303 . With an AC voltage applied between the electrical connections  3304 , with the AC voltage having a frequency more than 20 kHz, the piezo element  3303  produces ultrasonic vibrations that couples with the specimen conduit  3301  through direct contact between piezo element  3303  and the specimen conduit  3301 , which further couples to the specimen  3302  contained within the specimen conduit  3301 . With the specimen conduit  3301  having a design of its shape, material property, and dimensions of the containment where specimen  3302  resides, specimen conduit  3301  functions as a fluidic channel, for example a micro-fluidic channel, where the ultrasonic vibration from the piezo element  3303  produces pushing force to cause a fluidic flow that forces the specimen  3302  to flow in the direction  3333  and out of the conduit  3301  through the outlet  3309 . 
       FIG. 33D  illustrates an example of specimen pump  3211  of  FIG. 32D , including a rotary motor  3305  and a flexible conduit  3301  and specimen  3302  contained therein. At least one motor arm  3306  is located on the circumference of the motor  3305 , such that when the motor  3305  rotates in the  3307  direction, the at least one arm  3306  comes into contact with the external wall of the flexible conduit  3301 . With a continued rotation of the motor  3305  and movement of the arm  3306 , the conduit  3301  is compressed as shown by the conduit compression  3334  in  FIG. 33D , whereas such compression  3334  of the conduit  3301  moves from top to down along the direction  3333  until arm  3306  moves away from the conduit  3301  following the rotation  3307  of the motor  3305 , at which time the compression  3334  may return to the original non-compressed shape of conduit  3301  wall. The compression  3334  movement forces, or squeezes, the specimen  3302  to flow in the direction of  3333  outside of the conduit  3301  and through the outlet  3309 . Rotation  3307  of motor  3305  may be electrically driven through the electrical connections  3308  of  FIG. 32D . 
       FIG. 33E  illustrates an example of specimen pump  3211  of  FIG. 32D , including alternating valves  3310  and a flexible conduit  3301  and specimen  3302  contained therein. Valves  3310  may be placed on only one side of the conduit  3301 , or two sides of the conduit  3301  as shown in  FIG. 33E . At least two valves  3310  are positioned at two different locations on the conduit  3301  wall along the  3333  direction.  FIG. 33E  shows that a set of upper valves  3310  move away from each other along the  3311  directions, which in turn cause the flexible conduit  3301  walls connected to the upper valves  3310  to bend accordingly as shown by  3335  and the wall spacing of the conduit  3301  between the upper valves  3310  increases. Such increase of conduit  3301  spacing at upper valves  3310  location leads to decrease specimen  3302  pressure, which causes more specimen  3302  to move into the increase spacing area of the conduit from inside the housing  3201  as in  FIG. 32D . Meanwhile,  FIG. 33E  shows that a set of lower valves  3310  move closer to each other along the  3312  directions, which in turn cause the flexible conduit  3301  walls connected to the upper valves  3310  to bend accordingly as shown by  3336  and the wall spacing of the conduit  3301  between the lower valves  3310  decrease, preferably to zero wall spacing. Such decrease of conduit  3301  spacing at lower valves  3310  location forces, or squeezes, the specimen  3302  originally in the conduit  3301  space at the lower valves  3310  location out of the conduit  3301  and through the outlet  3309  in  3333  direction. 
     Following the  FIG. 33E  valve movements, the upper valves  3310  may reverse their movement to  3312  directions to be closer to each other and reduces the wall spacing of conduit  3301  at upper valves  3310  location, preferably to zero wall spacing. Meanwhile, the lower valves  3310  may also reverse their movement to  3311  directions to be away from each other and increases the wall spacing of conduit  3301  at lower valves  3310  location. The reversed movements of the upper and lower valves  3310  cause the specimen  3302  originally contained within the conduit  3301  space around the upper valves  3310  location to move to the conduit  3301  space around the lower valves  3310  location. Then, a following valve movements as shown in  FIG. 33E  may force, or squeeze, the specimen  3302  in the conduit  3301  space at the lower valves  3310  location out of the conduit  3301  and through the outlet  3309  in  3333  direction. A repeated movements and reverse movements of the valves  3310  may provide a pumping function to pump the specimen  3202  out of the housing  3201  through the outlet  3209  of  FIG. 32D . Movements of the valves  3310  in directions  3311  and  3312  may be produced by a driver connected to the valves  3310 , or being part of valves  3310 , which are controlled by electrical signal from the electrical connections  3208  of  FIG. 32D . 
       FIG. 33F  illustrates an example of specimen pump  3211  of  FIG. 32D , including electrodes  3321  and  3322  embedded in a conduit  3301  and specimen  3302  contained therein. Each of the electrodes  3321  and  3322  may have an electrical connection  3323  attached, which are similar as the electrical connection  3208  of  FIG. 32D . A first electrical voltage may be applied to the upper electrodes  3321  through the electrical connections  3323 , which may produce a first dielectric polarization in the specimen  3302 , or may inject a first electric charge, for example electrons, in the specimen  3302  when the electrodes  3321  are in contact with the specimen  3302 . Then a second electrical voltage may be applied to the lower electrodes  3322  through the electrical connections  3323 , which may produce an electric field in the specimen  3302  that provide an electrical attraction to the first dielectric polarization in the specimen  3302 , or provides an electrical attraction to the first electric charge, for example a positive voltage on the electrodes  3322 . Such electrical attraction may cause the specimen  3302  to move in the direction  3333  and eventually out of the conduit  3301  through the outlet  3309 . The first and second voltages may be applied in the form of pulses or AC voltage. The first and second voltages may have different amplitude, polarity, pulse width or frequency. 
     Now referring back to  FIG. 32D , specimen outlet  3209  is located in the housing  3201  wall that is orthogonal to the piston  3203  moving directions. The outlet  3209  contains a flow gate  3207 , which can open and shut off the specimen  3202  flow towards outside the housing  3201  through the outlet  3209 . In a dispensing operation, flow gate  3207  opens, and the pump  3211  forces the specimen  3202  to flow outside of the housing  3201  through the outlet  3209 . When flow gate  3207  shuts off, specimen  3202  is contained within the housing  3201  and pump  3211  does not produce a dispensing of the specimen  3202  or a movement of the piston  3203  due to specimen  3202  is blocked by the flow gate  3207 .  FIG. 32D  also shows that the dispenser housing  3201  has surface electrical contacts  3205 , whereas electrical connections  3208  may connect the electrical contacts  3205  to one or more of: the embedded electronic component  3206 , a specimen remaining volume sensor  3210 , the specimen pump  3211 , and the flow gate  3207 . As illustrated in  FIG. 32D , through the electrical contacts  3205  and the connections  3208 , one or more of the components, including but not limited to: the embedded electronic component  3206 , a specimen remaining volume sensor  3210 , the specimen pump  3211 , and the flow gate  3207 , may be controlled electrically by an electrical control unit, for example control unit  17  in  FIG. 14  and  FIG. 15 , that is external to the housing  3201 . The embedded electronic component  3206  may be any of: a control unit that controls the specimen remaining volume sensor  3210  or the flow gate  3207  or the specimen pump  3211  through circuits embedded in the housing  3201 , a logic unit, a data processer, a CPU, a memory, a data communication device including WIFI chip, RFID chip and Bluetooth chip, an information storage device that is similar to the same component  142  as in  FIG. 14  and  FIG. 15 . 
     To control specimen dispensing from dispensers having various mechanically operated flow valves as shown in  FIG. 23B  through  FIG. 23D ,  FIG. 34A  illustrates a specimen dispenser that is identical to the dispenser  14  of  FIG. 23B , in the form of a cartridge having a propellant  2323  driven piston  2318  and a flow valve  2325  being controlled by externally applied different types of pressure.  FIG. 23B  being used in  FIG. 34A  is only for description purpose. Principles as described in  FIG. 34A  and  FIG. 34B  may be applied to other specimen dispensers with mechanically operated flow values without limitation. Same as in  FIG. 23B ,  FIG. 34A  shows that the valve switch  2324  is mechanically operated, whereas an externally applied pressure, for example first pressure applied on valve switch  2324  in direction  3401  or second pressure in direction  3402 , will be transferred to a mechanical response from the flow valve  2325  and causes the flow valve  2325  to turn on. When the flow value  2325  is turned on, the specimen  2320  is forced out of the outlet  2352  by the propellant  2323  pressure on the piston  2318 . After the externally applied pressure is removed from the valve switch  2324 , flow value  2325  will return of shut off state. Outlet  2352  pass through both valve switch  2324  and flow valve  2325  and reaches into the specimen space  2320 . 
       FIG. 34B  illustrates methods to control the specimen  2320  dispense amount from the dispenser of  FIG. 34A  by controlling the pressure applied to the valve switch  2324 . Each of the three plots of the  FIG. 34B  has an identical horizontal axis to represent time of pressure applied to the valve switch  2324  in either  3401  or  3402  direction of  FIG. 34A . Each of the three plots of the  FIG. 34B  has an identical vertical axis to represent degree of pressure applied to the valve switch  2324  of  FIG. 34A , with the degree of pressure being labeled as the pushing depth of the valve switch  2324 , whereas for the mechanically operation valve switch  2324 , the more mechanical movement of the valve switch  2324  produced by the pressure in either  3401  or  3402  directions, with the movement being labeled as pushing depth in  FIG. 34B , the larger the opening that is produced in the flow valve  2325 , and the more amount of specimen  2320  is dispensed from dispenser  14  in a unit time. Each plot of  FIG. 34B  shows a pulse function representing the application and pushing depth applied to valve switch  2324  in  FIG. 34A . The bottom level  3400  represents zero pressure applied to valve switch  2324  and flow gating  2325  being shut off. The arrows  3403 ,  3405 ,  3407  arising from the bottom level  3400  represent three different pushing depth of the pressure, which are also the amplitudes of the three pulses indicating different flow valve  2325  open degrees, with  3407  being the widest opening and  3403  being the smallest opening in flow valve  2325 . The arrows  3404 ,  3406 ,  3408  represent the time that pressure is applied to the valve switch  2324 , which are also the pulse width of the three plots and indicate the flow valve  2325  open time, with  3408  being the longest and  3404  being the shortest in open time of the flow valve  2325 . For lower plot of  FIG. 34B  showing a pressure pulse applied to valve switching having a pulse amplitude  3403  and pulse width  3404 , it has the shortest flow gate  2325  opening time  3404  and smallest pushing depth  3403 , and thus produces least amount of specimen  2320  dispensing from cartridge  14 . For middle plot of  FIG. 34B  showing a pressure pulse applied to valve switching having a pulse amplitude  3405 , it has the same flow gate  2325  opening time  3406  and larger pushing depth  3405  compared to  3404  and  3403  of the lower plot of  FIG. 34B , and thus produces more amount of specimen  2320  dispensing from cartridge  14  than in lower plot of  FIG. 34B . For upper plot of  FIG. 34B  showing a pressure pulse applied to valve switching having a pulse amplitude  3407  and pulse width  3408 , it has the a longer flow gate  2325  opening time  3408  and same pushing depth  3407  compared to  3406  and  3405  of the middle plot of  FIG. 34B , and thus produces even more amount of specimen  2320  dispensing from cartridge  14  than in middle plot, and also the most amount of the specimen  2320  dispensing from cartridge  14  among the three plots of  FIG. 34B . 
     To control specimen dispensing from dispensers having various electrically operated specimen flow gate, for example flow gates  3107  and  3207  as shown in  FIG. 31A  through  FIG. 32D ,  FIG. 34C  illustrates a specimen dispenser that is identical to the dispenser of  FIG. 32C , in the form of a specimen dispenser having surface electrical contacts  3205 , embedded electrical components  3206 ,  3210 , a propellant  3214  driven piston  3203  and electrical signal controlled flow gate  3207 .  FIG. 32C  being used in  FIG. 34C  is only for description purpose. Principles as described in  FIG. 34C  and  FIG. 34D  may be applied to other specimen dispensers with electrically operated specimen flow gates without limitation. Same as in  FIG. 32C ,  FIG. 34C  shows that the flow gate  3207  may be electrically operated, whereas a first electrical signal applied to the flow gate  3207  though the connection  3208  which further connects to the contact pads  3205 , is capable of turning on the flow gate  3207  to allow the specimen  3202  to be dispensed from the dispenser housing  3201 . The first electrical signal applied to the flow gate  3207  may be applied by an electrical control unit, for example control unit  17  as in  FIG. 14  and  FIG. 15 , that is external to the housing  3201 . After the applied first electrical signal is removed from the flow gate  3207 , flow gate  3207  may return to shut off state to stop specimen  3202  dispensing from the dispenser housing  3201 . Alternatively, a second electrical signal may be applied to the flow gate  3207  through the connection  3208  to change the flow gate  3207  into shut off state. 
       FIG. 34D  illustrates methods to control the specimen  3202  dispensing amount from the dispenser of  FIG. 34C  by an electrical signal applied to the flow gate  3207  of  FIG. 34C . Each of the three plots of the  FIG. 34D  has an identical horizontal axis to represent time of the electrical signal applied to the flow gate  3207  of  FIG. 34C . Each of the three plots of the  FIG. 34D  has an identical vertical axis to represent the flow gate  3207  open width, which may be related to the amplitude of the electrical signal applied to the flow gate  3207 , for example a higher amplitude electric voltage or electric current applied to the flow gate  3207  may produce a wider opening of the flow gate  3207  to allow more amount of specimen  3202  to be dispensed from dispenser housing  3201  of  FIG. 34C  in a unit time. Each plot of  FIG. 34D  shows a pulse function representing the duration of the electrical signal applied to the flow gate  3207  in  FIG. 34C , and electrical signal generated open width of the flow gate  3207  in  FIG. 34C , whereas the pulse of each plot may also be treated as a pulse of the electrical signal applied to the flow gate  3207  with a pulse duration and pulse amplitude. The bottom level  3410  represents zero opening of the flow gate  3207 , or shut off of the flow gate  3207 . The arrows  3413 ,  3415 ,  3417  arising from the bottom level  3410  represent three different opening width of flow gate  3207 , which indicate three different electrical signals applied to the flow gate  3207 , with  3417  being the widest opening and  3413  being the smallest opening in flow gate  3207 . The arrows  3414 ,  3416 ,  3418  represent the duration of the flow gate  3207  opening in each of the plots, which also indicate the pulse duration of the electrical signals applied to flow gate  3207 , with  3418  being the longest and  3414  being the shortest pulse duration. For lower plot of  FIG. 34D  showing flow gate  3207  opening cause by application of electrical signal to the flow gate  3207 , it has a pulse amplitude  3413  and pulse width  3414 , it has the shortest flow gate  3207  opening duration  3414  and smallest flow gate  3207  opening width  3413 , and thus produces least amount of specimen  3202  dispensing from dispenser of  FIG. 34C . For middle plot of  FIG. 34D  showing flow gate  3207  opening cause by application of electrical signal to the flow gate  3207  having a pulse amplitude  3415  and pulse duration  3416 , it has the same flow gate  3207  opening duration  3416  and wider opening  3415  compared to  3414  and  3413  of the lower plot of  FIG. 34D , and thus produces more amount of specimen  3202  dispensing from dispenser of  FIG. 34C  than in lower plot. For upper plot of  FIG. 34D  showing flow gate  3207  opening cause by application of electrical signal to the flow gate  3207  having a pulse amplitude  3417  and pulse duration  3418 , it has the a longer flow gate  3207  opening duration  3418  and same opening width  3417  compared to  3416  and  3415  of the middle plot of  FIG. 34D , and thus produces even more amount of specimen  3202  dispensing from dispenser of  FIG. 34C  than in middle plot, and also most amount of the specimen  3202  dispensing from dispenser of  FIG. 34C  among the three plots of  FIG. 34D . 
       FIG. 35A  through  FIG. 35D  illustrate dispensing various amounts of specimen  3202  from dispenser housing  3201  of  FIG. 34C  and  FIG. 32C  with a method that is different than what was described in  FIG. 34D . 
       FIG. 35A  illustrates specimen dispenser same as  FIG. 34C  having surface electrical contacts  3205 , embedded electrical components  3206 ,  3210 , a propellant  3214  driven piston  3203  and electrical signal controlled flow gate  3207 .  FIG. 35A  dispenser is only for description purpose. Principles as described in  FIG. 35A  through  FIG. 35D  may be applied to other specimen dispensers with electrically operated specimen flow gates without limitation. 
       FIG. 35B  illustrates specimen  3202  dispensing from the dispenser of  FIG. 35A  in a unit volume by a single pulse of electrical signal applied to the flow gate  3207  of  FIG. 35A .  FIG. 35B  is similar to any one of the plots of the  FIG. 34D , with the pulse width  3512  representing the duration of the flow gate  3207  being open, and pulse amplitude  3513  representing the open width of the flow gate  3207 . Pulse width  3512  together the pulse amplitude  3513  determine a specific amount of specimen  3202  being dispensed from the dispenser in  FIG. 35A , which is also referred to as a Unit Dispense of the specimen  3202 . 
       FIG. 35C  illustrates the method to produce the specimen  3202  dispensing in a first amount from the dispenser of  FIG. 35A  by a number of pulses of the electrical signal applied to the flow gate  3207 . In  FIG. 35C , dispensing of the specimen  3202  is always produced by a number of repeated pulses of  FIG. 35B  within a given time slot  3514 . For  FIG. 35C , three pulses are used as example to show that three Unit Dispenses are performed according the  FIG. 35B  unit dispense scheme, which is referred to as Less Dispense. 
       FIG. 35D  illustrates method to produce the specimen  3202  dispensing in a second amount from the dispenser of  FIG. 35A  by another number of pulses of electrical signal applied to the flow gate  3207 . In  FIG. 35D , dispensing of the specimen  3202  within the same duration of a given time slot  3514  as in  FIG. 35C , six pulses are used as example to show that six Unit Dispenses are performed according the  FIG. 35B  unit dispense scheme, which is referred to as More Dispense. With the six Unit Dispenses within time slot  3514 , the amount of the total specimen  3202  dispensed in  FIG. 35D  is twice the amount of the total specimen  3202  dispensed in  FIG. 35C . 
     According the method of using different number of Unit Dispense pulses to dispense various amount of specimen  3202  as illustrated in  FIG. 35C  and  FIG. 35D , the dispensing of specimen  3202  from specimen dispenser can now be digitally controlled with a volume precision determined by the Unit Dispense specimen volume. For example, for a specimen dispenser that is capable of producing 1 micro-liter (uL) specimen  3203  volume in each Unit Dispense, a first user requiring a 5 uL specimen will need five Unit Dispenses, while a second user requiring an 8 uL will need eight Unit Dispenses. While for a specimen dispenser that is capable of producing 0.1 uL specimen  3203  volume in each Unit Dispense, the first user may ask for 5.1 uL composed of 51 Unit Dispenses for a better accuracy to meet first user&#39;s need, while the second user may ask for 8.3 uL composed of 83 Unit Dispenses for better accuracy to meet second user&#39;s need. The dispensing method as demonstrated in  FIG. 35B  through  FIG. 35D  may couple with the pulse amplitude variations, as shown in  FIG. 34D  to achieve more level of precision of specimen  3203  dispensing amount control, which not only utilizes the number of Unit Dispense pulses as shown in  FIG. 35C  and  FIG. 35D  to control the amount of specimen  3202  dispensing, the gate open width of a Unit Dispense may also vary, such that for the same number of Unit Dispensing pulses, the specimen amount dispensed may be different depending on the gate open width of each of the Unit Dispense pulse. For example, to achieve a 5.3 uL dispensing of the specimen  3203 , five pulses of a first Unit Dispense having a first gate open width that enables 1 uL dispense for each Unit Dispense, and three pulses a second Unit Dispense having a second gate open width that enables 0.1 uL dispense for each Unit Dispense, may be combined in various sequence to produce the 5.3 uL dispensed specimen  3202  volume. 
     Now referring back to  FIG. 3 .  FIG. 3  is a schematic diagram illustrating a specimen dispenser  14  which has multiple sub-dispensers. The sub-dispensers are physically separated dispensers by themselves. Each sub-dispenser has a conduit  149  that connects to the outlet  15  on the surface  12 , where the conduits  149  converge at or in close proximity to the outlet  15 . Before the convergence point, the conduits  149  are separated to avoid cross-contamination of the specimen from different sub-dispensers. The sub-dispensers are referred to as dispenser  14  as a whole entity. However, when dispenser  14  is replaced, all sub-dispensers may be replaced together, or replaced individually. 
       FIG. 4  is a schematic diagram illustrating a specimen dispenser  14  having multiple compartments. The dispenser  14  has a physical containment body where the compartments reside. During specimen dispensing, the compartments may function similar as independent dispensers by themselves. Each compartment has a conduit  149  that connects to the outlet  15  on the surface  12 , where the part of or entire conduit  149  may exist within the dispenser body. The conduits  149  from different compartments converge at or in close proximity to the outlet  15 . Before the convergence point, the conduits  149  are separated to avoid cross-contamination of the specimen from different sub-dispensers. When the dispenser  14  is replaced, specimens in all compartments are replaced together. 
       FIG. 36  illustrates removable specimen cartridges, also referred to as specimen dispensers or specimen sub-dispensers,  3601 ,  3611 , and  3621 , being inserted into a slot  3604  in a device body  3603  with each dispense having a separate specimen outlet  3605 ,  3615  and  3625 , in the device body  3603 , whereas the device body  3603  as in  FIG. 36  only shows partial body of a specimen dispensing device where a specimen dispenser is contained.  FIG. 36  is substantially similar as  FIG. 29  with the exception of having multiple dispensers  3601 ,  3611 , and  3621  that may combine into a single dispenser set. The device body  3603  of  FIG. 36  is substantially similar as the device body  11  of device  10  as in  FIG. 1  and  FIG. 2 . Specimen dispensers  3601 ,  3611 , and  3621 , and specimen outlets  3602 ,  3612  and  3622 , at the bottom of each corresponding dispensers respectively, are substantially similar as specimen dispenser  14  and any of the specimen outlet  2252 ,  2352  and  2452  as in  FIG. 22A  through  FIG. 24B . The nozzle portion of specimen outlet  3602 ,  3612  and  3622  may have sufficiently similar structures and functions as any of the outlet nozzles  2503 ,  2506 ,  2606 ,  2608 ,  2703 , and  2803  as described in  FIG. 25A  through  FIG. 28D . In  FIG. 36 , the dispensers  3601 ,  3611 ,  3621 are inserted into the device body  3603  and positioned into the slot  3604  as a dispenser set, with the specimen dispenser outlets  3602 ,  3612  and  3622  aligned to and inserted into the outlets  3605 ,  3615  and  3625  of the device body  3603 . Directions of  3606 ,  3616 , and  3626  show how specimen dispensers  3601 ,  3611  and  3621  are inserted into the slot  3604  of the device body  3603 , with specimen dispenser outlets,  3602 ,  3612 ,  3622  inserted into the device outlets  3605 ,  3615  and  3625 . Specimen is contained within each of the specimen dispensers  3601 ,  3611  and  3621 , and dispensed through the specimen outlets  3602 ,  3612 ,  3622 , and consequently the device specimen outlets  3605 ,  3615  and  3625  when specimen dispensers  3601 ,  3611  and  3621  are positioned within the slot  3604  of device body  3603 . Dispensing of specimen from dispenser  3601 ,  3611  and  3621  may be through any methods as described in  FIG. 22A  through  FIG. 24B . 
       FIG. 37  illustrates the specimen dispensers  3601 ,  3611  and  3621  of  FIG. 36  being combined into a single dispenser set  3700  and inserted into the slot  3604  of device body  3603 , whereas the device body  3603  as in  FIG. 37  only shows partial body of a specimen dispensing device where a specimen dispenser is contained. Dispensers  3601 ,  3611  and  3621 , dispenser outlet  3602 ,  3612 , and  3622 , device body  3603 , slot  3604  and device outlets  3605 ,  36015 ,  3625 , are identical to the corresponding entities having same labeled numbers in  FIG. 36 .  FIG. 37  illustrates that the specimen dispensers  3601 ,  3611  and  3621  are combined into a single dispenser set  3700 , whereas the dispensers  3601 ,  3611  and  3621  may have features including any of: matching external physical shapes, external mechanical hooking points that attach one dispenser to another, or magnetic hooking points that are made of permanent magnets or magnetic materials that attract one dispenser to another, which may enable the dispensers to be assembled or grouped into the dispenser set  3700  easily.

       FIG. 43  illustrates removable specimen dispenser  4313 , which may have sub-compartments  4301 ,  4311 ,  4321  contained therein, and surface contact pads  4307 , being inserted into or removed from a slot  4304  in a device body  4303 , whereas the slot  4304  has electrical contacts  4308  embedded in the inside wall, and whereas the device body  4303  as in  FIG. 43  only shows partial body of a specimen dispensing device where specimen dispenser is contained. Sub-compartments  4301 ,  4311 ,  4321  may be enclosed in the body of specimen dispenser  4313 , and may be stationary and not removable from the specimen dispenser  4313 . Each of the Sub-compartments  4301 ,  4311 ,  4321  may have an embedded electronic component  4320  with electrical connections  4321  connecting the electronic component s  4320  to the surface contact pads  4307 , whereas the embedded electronic component  4320  may provide function of any of: (a) data communication through electrical connections  4321  and the surface contact pads  4307  with any electronics contained in the device body  4303 ; (b) identification and authentication of sub-compartments  4301 ,  4311 ,  4321  and specimen contained therein; (c) obtaining information regarding specimen contained in each of sub-compartments  4301 ,  4311 ,  4321  for any of: remaining volume, specimen type, specimen physical or chemical properties such as viscosity, temperature, composition and pressure; (d) storing and providing information regarding specimen contained in each of sub-compartments  4301 ,  4311 ,  4321  for any of: physical or chemical properties such as viscosity, temperature, composition and pressure specimen, purpose of specimen for skin care treatment, method of dispensing or mixing specimen, method of using specimen for a specific skin condition; and (e) providing electric power to sub-compartments  4301 ,  4311 ,  4321 , and driving of specimen dispensing from sub-compartments  4301 ,  4311 ,  4321 . 
     Each of the sub-compartments  4301 ,  4311 ,  4321  may have an outlet  4305 ,  4315 , or  4325  respectively. Conduits  4357  may connect each of the outlets  4305 ,  4315 ,  4325  to the outlet  4330  of dispenser  4313 , whereas specimen is dispensed from inside the sub-compartments  4301 ,  4311 ,  4321  through the outlets  4305 ,  4315 ,  4325 , and then through the conduits  4357 , and then mixed at and dispensed through the dispenser outlet  4330  outside the body of dispenser  4313 .  FIG. 43  is similar as  FIG. 30  with the exception of having multiple sub-compartments  4301 ,  4311 , and  4321  that are enclosed in the dispenser  4313 . The device body  4303  of  FIG. 43  is substantially similar as the device body  11  of device  10  as in  FIG. 1  and  FIG. 2 , or device body  3003  of  FIG. 30 . Dispensing of specimen from sub-compartments  4301 ,  4311  and  4321  may be through any methods, and substantially similar specimen driving mechanism as described in any of the specimen dispensers in  FIG. 31A  through  FIG. 35D . The nozzle portion of specimen outlet  4330  of dispenser  4313  may have sufficiently similar structures and functions as any of the outlet nozzles  2503 ,  2506 ,  2606 ,  2608 ,  2703 , and  2803  as described in  FIG. 25A  through  FIG. 28D . In  FIG. 43 , the dispenser  4313  is inserted into the device body  4303  and positioned into the slot  4304 , with the specimen dispenser outlet  4330  aligned to and inserted into the outlets  4331  of the device body  4303 . Direction of  4316  shows how specimen dispenser  4313  is inserted into the slot  4304  of the device body  4303 , with specimen dispenser outlets  4330  inserted into the device outlets  4331 . Specimen contained within each of the specimen sub-compartments  4301 ,  4311  and  4321 , is dispensed through the specimen outlets  4305 ,  4315 ,  4325 , then through the conduits  4357 , then through the dispenser outlet  4330 , and then the device specimen outlet  4331 . 
     The surface electrical pads  4307  on the external walls of the dispenser  4313  may make contact with the electrical contacts  4308  built-in the inside wall of the slot  4304  when the dispenser  4313  is inserted into the slot  4304 . The electrical connections  4309  in contact with the electrical contacts  4308  may connect the electrical contacts  4308  to other electronic components within the device body  4303 . The electrical contacts  4308  and electrical connections  4309  are substantially similar as the contacts  3008  and connections  3009  of  FIG. 30 , as well as electrical connection  143  of  FIG. 14  and  FIG. 15 . The electrical connections  4309  may be contained in bundle  4310  in the form of electrical wires  4309  contained in a cable  4310 , or as electrical paths  4309  contained in a flat flexible substrate  4310 . The surface electrical pads  4307  are also substantially similar as electrical contact pads  3007  of  FIG. 30  as well as contact pads  141  of  FIG. 14  and  FIG. 15 . The electrical connections  4309  may ultimately connect to other electronics in device body  4303  that is substantially similar as the control unit  17  of  FIG. 14  and  FIG. 15 . In  FIG. 43 , after the electrical contacts  4308  make physical contact with the electrical pads  4307 , electrical signals can be sent to, or retrieved from, the embedded electronic components  4320  of the dispenser  4313  through the connections  4321  and  4309 , by electronics, for example control unit  17  as in  FIG. 14  and  FIG. 15 , contained in the device body  4303 . 
     Similar as in  FIG. 36 , even though  FIG. 43  shows dispenser outlet  4330  are inserted into the device outlet  4331 , another embodiment may provide dispenser outlet  4330  bottom surface being in tight contact with the top surface of the device outlet  4331  after dispenser  4313  is inserted into slot  4304 , and specimen is dispensed from dispensers  4313  through dispenser outlet  4330  and then the device outlets  4331 . 
       FIG. 44  illustrates specimen dispensers  4401 ,  4411 , and  4421  being combined into a set and inserted into a dispenser slot  4404  in a device body  4403 , whereas physical features  4407 ,  4408  and  4409  are used to assist dispenser positioning and alignment.  FIG. 44  is sufficiently similar as  FIG. 37 , with dispensers  4401 ,  4411 ,  4421 , dispenser outlets  4402 ,  4412 ,  4422 , slot  4404 , device body  4403 , and device outlets  4405 ,  4415 ,  4425  being sufficiently identical to the dispensers  3601 ,  3611 ,  3621 , dispenser outlets  3602 ,  3612 ,  3622 , slot  3604 , device body  3603 , and device outlets  3605 ,  3615 ,  3625  of  FIG. 37 . Dispensers  4401 ,  4411 ,  4421  are inserted in the slot  4404  of device body  4403  along  4406  direction, which is also sufficiently similar as dispensers  3601 ,  3611 ,  3621  being inserted in the slot  3604  of device body  3603  along  3606  direction as in  FIG. 37 . 
     Dispensers  4401 ,  4411 ,  4421  of  FIG. 44  may have physical features  4407 , which may be the curvatures of the physical shapes of the dispensers  4401 ,  4411 ,  4421  as shown in  FIG. 44 , that enable the dispensers  4401 ,  4411 ,  4421  to be assembled into a dispenser set in a specific configuration or orientation, whereas changing of the relative orientations of the dispensers  4401 ,  4411 ,  4421  from this specific configuration or orientation may render the dispenser set not cylindrical or not physically possible to be inserted into the slot  4404  of device body  4403 . Dispensers  4401 ,  4411 ,  4421  of  FIG. 44  may have also physical features  4408 , which may take the form of an alignment ridge  4408  on the dispenser  4401  as shown in  FIG. 44 , that is preferred to be matching to another physical feature  4409  in the slot  4404  inside wall, for example the alignment slot  4409  in the slot  4404  inside wall. The matching physical features  4408  and  4409  may help align the dispensers  4401 ,  4411 ,  4421  during their insertion into the slot  4404 , such that the dispenser outlets  4402 ,  4412 ,  4422  may be aligned precisely to the locations of the device outlets  4405 ,  4415 ,  4425  during the insertion of the dispensers  4401 ,  4411 ,  4421 , whereas a user inserting the dispensers  4401 ,  4411 ,  4421  does not need extra effort to align the dispenser outlets  4402 ,  4412 ,  4422  to the device outlets  4405 ,  4415 ,  4425 . For example, as  FIG. 44  shows, dispensers  4401 ,  4411 ,  4421  are first assembled into a dispenser set according to the physical feature  4407 , and then the dispenser set is inserted into the slot  4404  with the alignment ridge  4408  on dispenser  4401  aligned to and sliding into the alignment slot  4409 . With the dispensers  4401 ,  4411 ,  4421  in the form of the dispenser set sliding into the slot  4404 , alignment ridge  4408  sliding within alignment slot  4409  enables the dispenser  4401  having the outlet  4402  automatically aligned to, and inserted into, the device outlet  4405 . Due the dispensers  4411 ,  4421  are specifically oriented in the configuration of  FIG. 44  relative to the dispenser  4401  by curvature  4407 , and confined by the slot  4404  inside wall, the dispensers  4411 ,  4421  outlets  4412  and  4422  are also automatically aligned to, and inserted into, the device outlets  4415  and  4425 . The physical features  4408  that enable alignment of dispenser set alignment to the slot  4404  may exist on one or more dispensers of a dispenser set, with matching physical features  4409  existing at various locations of the inside wall of slot  4404 . The physical features similar to  4407 ,  4408 ,  4409  and together with the confinement of the internal wall of slot  4404  may enable each of the dispensers  4401 ,  4411 ,  4421  be inserted into the slot  4404  individually and aligned into specific orientations automatically. 
     Physical features  4407 ,  4408 ,  4409  of  FIG. 44  mainly serve to achieve fast and easy handling of dispensers for a user during replacement and insertion of the dispensers, with eliminating the possibility of putting wrong dispenser at a wrong location, or any possibility of confusion of whether a dispenser should be used in a cartridge set. Physical features  4407 ,  4408 ,  4409  may include any type of physical shapes, physical protrusions, physical indentations, physical grooves. For different dispenser sets that have different size dispensers, or different number of dispensers, within each different set, physical features  4407 ,  4408 ,  4409  may take different forms, shapes, locations, and sizes. Additionally, the physical features  4407 ,  4408 ,  4409  may also be, or combined with any of: colors of dispensers, or optical patterns on the dispensers&#39; external surfaces, that may match to certain color or optical patterns in or around the slot  4404  to enable easy matching. For example, the dispensers  4401 ,  4411 ,  4421  may be in color sequence of white, gray and green, whereas colored patterns of white, gray and green sections around the top opening of the slot  4404  may be used to indicate the corresponding designated locations of the dispensers  4401  (white),  4411  (gray),  4421  (green), and user may use such color matching to insert the dispensers  4401 ,  4411 ,  4421  into slot  4404  at corresponding color matching locations, which may also have the physical features  4407 ,  4408  and  4409  simultaneously for fast insertion and dispenser set assembly. 
     Evan through  FIG. 44  uses  FIG. 37  type of configuration for description purpose, the method as described in  FIG. 44  may be readily applied to the dispensers  3601 ,  3611 ,  3621  with device body  3603  or dispenser holder  3913  as in  FIG. 36  through  FIG. 39 . The method as described in  FIG. 44  may also be readily applied to the dispensers  4001 ,  4011 ,  4021 ,  4313  with device body  4003 ,  4303 , or dispenser holders  4113 ,  4213  as in  FIG. 40  through  FIG. 43 , wherein in addition to alignment of dispenser outlets to device outlets, fast and reliable alignment of dispenser surface electrical pads to electrical contacts in the slot wall of the device body may also be achieved by a user with using the physical features  4407 ,  4408 ,  4409 , and possibly together with color and optical patterns, as described in  FIG. 44 . 
       FIG. 45  illustrates various function groups containing different dispensers which may be selected and combined into different dispenser sets to produce different dispensed specimen having different skin care function with different specimen composition after mixture. For description purpose, three function groups, group- 1   4510 , group- 2   4520  and group- 3   4530 , with each group containing three types of dispensers, are used for illustration in  FIG. 45 . In practice, number of groups and type of dispensers within each group may vary. With any one dispenser selected from each of the three different groups,  4510 ,  4520 ,  4530 , a total of three dispensers may form a single dispenser set. In one embodiment, each of the function groups  4510 ,  4520 ,  4530  may contain different types of sub-compartments, whereas sub-compartments from different groups may form a single dispenser with a plurality of sub-compartments, for example sub-compartments  4301 ,  4302 , and  4303  of  FIG. 43  may each belong to a different function group of sub-compartments. However, in  FIG. 45 , groups  4510 ,  4520 ,  4530  will be referred to hereafter as groups of dispensers, or cartridges, for the purpose of explanation, but can be similarly described as sub-compartments as shown in  FIG. 43 . Dispensers as described in  FIG. 45  may be applied to dispensers or sub-compartments of any other embodiments or figures of this invention. 
     Group- 1   4510  as shown in  FIG. 45  contains cartridges  4511 ,  4512 , and  4513 , and Group- 2   4520  is shown to contain cartridges  4521 ,  4522 , and  4523 , and Group- 3   4530  is shown to contain cartridges  4531 ,  4532 , and  4533 . Different groups of  4510 ,  4520  and  4530  may be created according to the skin care function of the cartridges contained in each group, with the cartridges from same group targeting same or similar skin conditions, or providing same or similar skin care functions. For example, group- 1   4510  may be targeting “fine line” skin feature on a user&#39;s forehead. Group- 2   4520  may be targeting “wrinkles” feature that is deeper than “fine lines”, for example smile lines around the mouth. Group- 3   4530  may be targeting “brown spots” feature that is of general facial area. Different cartridges in the same group, for example cartridges  4511 ,  4512 , and  4513  in group- 1   4510 , may contain specimen that may be different in “specimen aspects” of: contained specimen volume; specimen dispensing flow rate or dispense speed; specimen composition; specimen skin care function strength; specimen quality or grade; specimen chemical or biological properties; specimen physical properties including, but not limited to, appearance, viscosity, color, texture, smell, contained particle size; specimen response to a skin treatment member physical actions, whereas the skin treatment member may be any of an ultrasound generation plate applying ultrasound vibrations to skin, an electrode providing electric voltage or current to skin, optic component emitting radiation to skin, mechanical vibrator providing local vibration to skin; specimen cost of ownership; specimen response to targeted skin surface condition, including skin properties of, but not limited to, dryness, oiliness, hydration, PH value, or acquired chemicals from environment. 
     One example of different combination of different cartridges from different groups for different user&#39;s unique skin care need is that the composition of different cartridges can be different. For first user, group- 1   4510  cartridge  1 - 1  may have a composition that is suitable for first user&#39;s skin condition, which composition can either be matched as closest to first user&#39;s skin care need, or can be custom altered or tuned according to the skin condition of the first user, namely hard coding the first user&#39;s skin information as the customized composition of specimen within the cartridge  1 - 1 . For second user, group- 1   4510  cartridge  1 - 2  may either be matched as closest to second user&#39;s skin care need, or custom altered according to the skin condition of the second user, namely hard coding the second user&#39;s skin information as the customized composition of specimen within the cartridge  1 - 2 . Thus, even though cartridges  1 - 1  and  1 - 2  are both for the same skin care purpose, for example “fine line” feature reduction, their actual compositions may be different. Similarly, cartridges from other groups may be closely matched to or altered according to different user&#39;s skin care need. Composition is used as an example of “specimen aspects” that can be customized. Other “specimen aspects” as described in the above paragraph may also be matched or altered according to different user&#39;s own unique skin care need, and may be used a method to hard code user skin care requirement information into the cartridge selection or customization. Cartridges after being selected, altered or customized from each different group may then be used to form a physically matching set to fit into a device cartridge holder, for example as shown in  FIG. 36  through  FIG. 44 . 
     Different combination of various cartridges from different groups of  4510 ,  4520  and  4530  may also produce different final specimen mixture percentage when specimens from cartridges selected from the different groups are mixed to produce a final specimen for skin care. Cartridges within any one group of  4510 ,  4520  and  4530  may have same specimen, but different cartridges may have different contained specimen volume, for example large, medium, small volume, and different cartridges may have different specimen dispense rate or speed, for example fast, normal, and slow speed. For a first user that may require using more than normal amount of group- 1  specimen, normal amount of group- 2  specimen, and less than normal of group- 3  specimen than a typical user, the first user may order or custom combine: a group- 1  cartridge  1 - 1  that has a fast dispense speed and dispenses a larger than normal amount of group- 1  specimen in a single dispense or within a unit dispense time, where cartridge  1 - 1  may also contain a large specimen volume; a group- 2  cartridge  2 - 2  that has a normal dispense speed and dispenses a normal amount of group- 2  specimen in a single dispense or within a unit dispense time, where cartridge  2 - 2  may contain a normal specimen volume; and, a group- 3  cartridge  3 - 3  that has a slow dispense speed and dispenses a less than normal amount of group- 3  specimen in a single dispense or within a unit dispense time, where cartridge  3 - 3  may contain a small specimen volume, such that the combination of the three cartridges,  1 - 1 ,  2 - 2  and  3 - 3  makes a physically matching set to fit into a device cartridge holder, for example as shown in  FIG. 36  through  FIG. 44 . While a second user that has a skin condition characterized as “typical”, may choose cartridges  1 - 2 ,  2 - 2 ,  3 - 2 , which are cartridges among each group that have normal dispense speed and dispenses a normal amount of specimen of each group in a single dispense or within a unit dispense time, where these cartridges may contain a normal specimen volume. The combination of cartridges with different specimen dispense speed, coupled with different specimen volume contained within the cartridges, as discussed, may achieve not only making final specimen having the desired composition of final specimen mixing for skin care, it may also help achieve all cartridges depletion at roughly same time so that cartridges may be replenished, refilled, re-purchased or replaced as a set, instead of as individual cartridge, such that it saves user&#39;s time and effort. Such different combination of cartridges with different dispensing rate may also be used as a method to hard code user skin care requirement information into the selection scheme of the different cartridges from the different groups, whereas different users may have different dispensing rates of same type of cartridges within same group. 
     The different combination of cartridges from different groups, which may couple with customized alteration of the specimen aspects as described above, may produce final specimen for skin care after mixtures of specimens from the cartridges from different groups to achieve different skin care functions, or for different skin types, skin conditions, and may provide different degree of skin effectiveness, compatible with different environments or seasons, having different grade, price, usage time, produce different user feeling on skin or skin sensation.

     Feature sub-sections  5305 ,  5307 ,  5308 , and  5310  of user unique skin data section  5303  may include identification or description information of any common skin features that may be found on a user&#39;s skin and are of importance to skin treatment for a skin care purpose. Feature grade  5306 ,  5308 , and  5311  of user unique skin data section  5303  may include a data sequence that is composed of quantitative numerals, or qualitative numerals, or both, to describe the severity or strength of the corresponding skin features, as in feature sections  5305 ,  5307 ,  5308 , existing on user&#39;s skin. Any known skin feature that may exist on a user&#39;s skin may be assigned a sub-section of “feature” in section  5303  of the user data structure  5300 , and a “feature grade” accompanying that feature may also be assigned as a sub-section in section  5303  of the user data structure  5300 . For a feature that exists on a given user&#39;s skin, grade data may be assigned for that feature in section  5303  of the user data structure  5300 . While for a feature that does not exist on the user&#39;s skin, the feature grade value of that feature may be un-assigned, or may be assigned special numerals or characters to indicate the non-existence of such feature. For example, feature # 1   5035  may be assigned to “fine line” feature on a user&#39;s face, and feature # 2   5307  may be assigned to “wrinkle” feature on a user&#39;s face, while feature # 1  grade  5306  is used to store grade of “fine line” and feature # 2  grade  5308  is used to store grade of “wrinkle”. User A may have fine lines but not wrinkles, in which case the fine liner feature grade  5306  may be assigned a grade value, while the wrinkle feature grade  5308  may be left un-assigned or assigned a number zero as an indication of non-existence of wrinkle feature. New found feature of a certain user, which does not exist as a sub-section in the user unique skin data section  5303  of the user data structure  5300  of that user, may be added into the user unique skin data section  5303  of the user data structure  5300  of that user as a new feature having both feature and feature grade sub-sections, with updating the header section  5301  with relevant information that may include: addition of the new sub-sections of the new feature, the location, length and boundaries of the newly added sub-sections in the user data structure  5300 . 
     Each feature sub-section of  5305 ,  5307 ,  5308 , or  5310  may contain a unique identification code, or data sequence, to specifically identify a known skin feature. Each feature grade sub-section of  5306 ,  5308 , or  5311  may contain grades that are generated by a commonly accepted grading method. The feature identification codes and the grades may serve as part of a universal protocol to communicate the features and their grades across different dispensing devices, specimen cartridges, skin care analysis services, personal computing devices, and beauty clouds. The same method of features identification and grading may be adopted and practiced by different dispensing device makers, specimen cartridge makers, skin care service providers and different users.

Due to product (A) of  FIG. 55A  and product (B) of  FIG. 55B  being from different brands, cartridge ID (A)  5502  and cartridge ID (B)  5512  are different, and product (A)  5505  and product (B)  5515  are different. In the case that if product (A) and product (B) are intended for the same skin care purpose, feature (A)  5506  and feature (B)  5516  may be the same, while as product (A) and product (B) being from different brands, the method (A)  5507 , grade (A)  5508 , and algorithm (A)  5509 , which are used to calculate best method to dispense specimen product (A) according to the user&#39;s skin feature, may be different than the method (B)  5517 , grade (B)  5518 , and algorithm (B)  5519 , which are used to calculate best method to dispense specimen product (B) according to the same user&#39;s same skin feature. In another embodiment, product (A) and product (B) are intended for different skin care purposes and treating different skin features, feature (A)  5506  and feature (B)  5516  are different, whereas method (A)  5507 , grade (A)  5508 , and algorithm (A)  5509  are also different than the method (B)  5517 , grade (B)  5518 , and algorithm (B)  5519 . However, as the user is the same, user data  5504  and  5514  may be the same. As the product (A) of  FIG. 55A  and product (B) of  FIG. 55B  are from different brands, encryption key (A)  5519  and encryption key (B)  5529  may be different if encryption key is provided by dispenser or specimen manufacturer. Encryption key (A)  5519  and encryption key (B)  5529  may be same if encryption key is provided by the user&#39;s dispensing device or provided according to an encryption key provider that specifies the encryption keys  5519  and  5529  being the same for the same user. Encryption key (A)  5519  and encryption key (B)  5529  may be omitted from data structure  5500  and  5550  similarly as encryption key  5419  of  FIG. 54 . 
     In the case of a cartridge set, for example a cartridge set containing three cartridges: a cartridge # 1  for treating fine lines as cartridge  3601  of  FIG. 36  through  FIG. 39  or cartridge  4001  of  FIG. 40  through  FIG. 42 , a cartridge # 2  for treating deep wrinkles as cartridge  3611  of  FIG. 36  through  FIG. 39  or cartridge  4011  of  FIG. 40  through  FIG. 42 , a cartridge # 3  for treating brown spots as cartridge  3621  of  FIG. 36  through  FIG. 39  or cartridge  4021  of  FIG. 40  through  FIG. 42 , while cartridge # 1  and cartridge # 3  may be from brand (A) and cartridge # 2  may be from brand (B), all three cartridges have same dispenser data structures similar to  FIG. 54 ,  FIG. 55A  or  FIG. 55B  which contain relevant information regarding each of the cartridges, and which enable the three cartridges from different brands (A) and (B) to function together as a single set to be installed in a dispensing device, as in device  3603  of  FIG. 36  through  FIG. 39 , or device  4003  of  FIG. 40  through  FIG. 42 , to dispense a final specimen with a composition that matches to a user&#39;s skin features and skin care need. 
       FIG. 56  illustrates methods to provide personalized specimen dispense schemes  5607  and  5611  for two different users, user # 1  and user # 2 , based on the unique user data  5604  and  5609  of each user and dispenser data from a same dispenser set, or cartridge set. 
       FIG. 56  illustrates a cartridge set containing three cartridges: a cartridge # 1   5601  which may be similar as cartridge  3601  of  FIG. 36  through  FIG. 39  or cartridge  4001  of  FIG. 40  through  FIG. 42 , a cartridge # 2   5602  which may be similar as cartridge  3611  of  FIG. 36  through  FIG. 39  or cartridge  4011  of  FIG. 40  through  FIG. 42 , a cartridge # 3   5603  which may be similar as cartridge  3621  of  FIG. 36  through  FIG. 39  or cartridge  4021  of  FIG. 40  through  FIG. 42 , while cartridges  5601 ,  5602 , and  5603  may form a cartridge set to be installed in a dispensing device that is same as device  3603  of  FIG. 36  through  FIG. 39  or same as device  4003  of  FIG. 40  through  FIG. 42 , or same as the device  10  of  FIG. 2 , to dispense a final specimen with a composition that matches to a user&#39;s own skin care need. Cartridge # 1   5601  may be any one of the cartridges of group- 1   4510  of  FIG. 45 , and cartridge # 2   5602  may be any one of the cartridges of group- 2   4530  of  FIG. 45 , and cartridge # 3   5603  may be any one of the cartridges of group- 3   4530  of  FIG. 45 . Each of the cartridges  5601 ,  5602 , and  5603  may be described similarly as, and may include any functions of, any of the dispensers or cartridges as described in  FIG. 22A  through  FIG. 44 . 
     Cartridge # 1   5601  may contain a data storage component that is similar to information storage component  142  of  FIG. 2 , whereas the data storage component stores specimen information  5621 . Specimen information  5621  describes that cartridge # 1   5601  contains a specimen that is targeted to treat skin feature of “fine line”, with method of use being a Unit Volume (“UV”) of specimen contained in cartridge # 1   5601  is targeted to treat skin feature “fine line” that is graded as Grade 5. The skin feature of “fine line” and method of use as in specimen information  5621  may be stored in dispenser data structure same as any of the dispenser data structures  5400 ,  5500 , and  5550  of  FIG. 54 ,  FIG. 55A  and  FIG. 55B , whereas skin feature “fine line” is same as any of the features  5406 ,  5410  of  FIG. 54  or any of the features  5506  and  5516  of  FIG. 55A  and  FIG. 55B , and whereas the reference grade “Grade 5” is same as any of the feature base grades  5408 ,  5412  of  FIG. 54  or any of the feature base grades  5508  and  5518  of  FIG. 55A  and  FIG. 55B , and whereas the method to use, “Grade 5 per Unit Volume (UV)” may be defined as any of the “method to use”  5407 ,  5411  of  FIG. 54 , or any of the method  5507  and  5517  of  FIG. 55A  and  FIG. 55B . 
     Cartridge # 2   5602  functions similarly as cartridge # 1   5601  and may also contain a data storage component, whereas the specimen information  5622  contained in the data storage component of cartridge # 2   5602  describes that cartridge # 2   5602  contains a specimen that is targeted to treat skin feature of “wrinkle”, with method of use being a Unit Volume of the specimen contained in cartridge # 2   5602  is targeted to treat skin feature “wrinkle” that is graded as Grade 5. 
     Cartridge # 3   5603  functions similarly as cartridge # 1   5601  and may also contain a data storage component, whereas the specimen information  5623  contained in the data storage component of cartridge # 3   5603  describes that cartridge # 3   5603  contains a specimen that is targeted to treat skin feature of “brown spot”, with method of use being a Unit Volume of the specimen contained in cartridge # 3   5603  is targeted to treat skin feature “brown spot” that is graded as Grade 5. 
     The electronic control unit  17  of  FIG. 56  is same as the control unit  17  of  FIG. 2 . For two different users, user # 1  and user # 2 , the information storage component  171  of the control unit  17  of the dispensing device  10  of each of the two users contains different unique user data relating to each of the two users own skin care need. 
     User # 1  device unique user data  5604  may be contained in a data structure same as user data structure  5300  of  FIG. 53  and is retrievable from the information storage component  171  of the control unit  17  as shown by step  5674 . Unique user data  5604  may describe the user # 1  skin condition  5605  by including the existing skin features and the corresponding grades as: feature “fine lines” with a grade of 5, feature “wrinkle” with a grade of 8, and feature “brown spot’ with a grade of 2. User # 2  device unique user data  5609  may be contained in a data structure same as dispenser data structure  5300  of  FIG. 53  and is retrievable from the information storage component  171  of the control unit  17  as shown by step  5679 . Unique user data  5609  may describe the user # 2  skin condition  5610  by including the existing skin features and the corresponding grades as: feature “fine lines” with a grade of 2, feature “wrinkle” with a grade of 1, and feature “brown spot’ with a grade of 5. From the comparison of user # 1  skin condition  5605  and user # 2  skin condition  5610 , if a higher grade number means a stronger skin feature, user # 2  skin condition  5610  has less issues of “fine lines” and “wrinkle”, but more issues of “brown spot”, than user # 1  skin condition  5605 . Listed features and their grades as in user # 1  skin condition  5605  and user # 2  skin condition  5610  are same as the features  5305 ,  5307 ,  5310 , and feature grades  5306 ,  5308 ,  5311  of user data structure  5300  of  FIG. 53 . 
     Listed features “fine lines”, “wrinkle” and “brown spot” as in user # 1  skin condition  5605  and user # 2  skin condition  5610  are respectively treated by the cartridge # 1   5601 , cartridge # 2   5602  and cartridge # 3   5603 . Because user # 1  skin condition  5605  and user # 2  skin condition  5610  are different in the grades of same skin features, for user # 1  and user # 2  to use the same cartridge set composed of cartridge # 1   5601 , cartridge # 2   5602  and cartridge # 3   5603  to treat the different grades skin features of their skin, dispensing scheme needs to be different for user # 1  and user # 2 . 
       FIG. 56  illustrates that the specimen information  5621  of cartridge # 1   5601 , specimen information  5622  of cartridge # 2   5602  and specimen information  5623  of cartridge # 3   5603  are retrieved from cartridge # 1   5601 , cartridge # 2   5602  and cartridge # 3   5603  as shown by steps of  5613 , and processed together with the unique user data  5604 , as shown by step  5647 , from user # 1  dispensing device, to produce user # 1  cartridge set dispensing scheme  5607  that specifies dispensing recipe  5608  as: 1.0 UV specimen dispensing from cartridge # 1   5601 , 1.6 UV specimen dispensing from cartridge # 2   5602  and 0.4 UV specimen dispensing from cartridge # 3   5603 . Calculation of user # 1  dispensing recipe  5608  as illustrated in  FIG. 56  is by a proportional calculation, which ratios each skin feature&#39;s grade as in user # 1  skin condition  5605  relative to the base grade of same skin feature from the corresponding cartridge among the cartridge set. For example, for user # 1 , as “fine lines” grade on user # 1  skin is 5, which is same as the base grade 5 as in the specimen information  5621  of cartridge # 1   5601 , the dispensed specimen volume from cartridge # 1   5601  is then calculated as (5/5×1 UV)=1.0 UV; while “wrinkle” grade on user # 1  skin is 8, which is larger than the base grade 5 as in the specimen information  5622  of cartridge # 2   5602 , the dispensed specimen volume from cartridge # 2   5602  is then calculated as (8/5×1 UV)=1.6 UV; “Brown spot” grade on user # 1  skin is 2, which is smaller than the base grade 5 as in the specimen information  5623  of cartridge # 3   5603 , the dispensed specimen volume from cartridge # 3   5603  is then calculated as (2/5×1 UV)=0.4 UV. It needs to be noted that the proportional calculation method is only used in  FIG. 56  and other figures of this invention as an example and for explanation purpose only. Actual method of calculation of optimal dispensing recipe  5608  may follow a different algorithm, which may be stored in the “Algorithm to Match User Feature”  5409  and  5413  sections of dispenser data structure  5400  of  FIG. 54 , or sections  5509  and  5519  of data structures  5500  and  5550  of  FIG. 55A  and  FIG. 55B , and which data structures may be the specimen information  5621 ,  5622 ,  5623 . Calculation of the dispensing recipe  5608  from the specimen information  5621 ,  5622 ,  5623  and the user # 1  unique user data  5604  may be performed by any of: information processing component  172  of the control unit  17  in the dispensing device of user # 1 , for example dispensing device  4902  of  FIG. 50 ; a personal computing device  5020  of  FIG. 50 , which may communicate with the dispensing device  4902  as  5037  of  FIG. 50 ; a remote server of a beauty cloud  5040  of  FIG. 50 , which may communicate with the dispensing device  4902  of  FIG. 50  by a data link directly, or through software and data interface via a personal computing device  5020  as  5024  of  FIG. 50 . 
     Follow similar calculation method, user # 2  cartridge set dispensing scheme  5611  with dispensing recipe  5612  may also be calculated from the specimen information  5621 , 5622 , 5623  as shown by  5614  in  FIG. 56 , together with the user # 2  unique user data  5609  as shown by  5691 . According to user # 2  skin condition  5610 , user # 2  cartridge set dispensing recipe  5612  specifies as: 0.2 UV specimen dispensing from cartridge # 1   5601 , 0.4 UV specimen dispensing from cartridge # 2   5602  and 1.0 UV specimen dispensing from cartridge # 3   5603 . 
     Skin features and their corresponding grades in skin conditions  5605 ,  5610  and specimen information  5621 ,  5622 , 5623  as in  FIG. 56  are used as example for illustration purpose, whereas actual skin features and their grades in application are not limited to listed features in  FIG. 56 . Examples given in  FIG. 56  do not limit how Unit Volume (“UV”) is defined for each skin feature. Base grade of specimen information  5621 ,  5622 ,  5623  as in  FIG. 56  does not limit the actual grading scheme that may be used in application. 
     Unit Volume (“UV”) as used in specimen information  5621 ,  5622 ,  5623  in  FIG. 56  may be a physical volume, for example a microliter, a milliliter, a five-microliter, a drop, or a single dispense action by a dispensing device, or a specimen volume that is designed for treatment of the base grade, i.e. Grade 5 as in  FIG. 56 , of each corresponding skin feature. Unit Volume of each of the cartridges  5601 ,  5602  and  5603  may also be adjusted in consideration of existence of other cartridges in the cartridge set. For a first cartridge, whereas existence of other cartridges in a cartridge set, may increase or decrease the skin feature treatment effectiveness of specimen from said first cartridge after specimen from all cartridges are mixed, due to chemical or physical interactions among the specimen, the UV of said first cartridge specimen dispensing amount will need to be adjusted accordingly. Alternatively, for a first cartridge, existence of other cartridges in a cartridge set, may increase or decrease the skin feature treatment effectiveness of specimen from said first cartridge after specimen from all cartridges are mixed due to same or similar functional elements in specimen from said first cartridge may also exist in specimen from other cartridges, thus the UV of said first cartridge specimen dispensing amount will also need to adjust accordingly. 
     For a cartridge set, different cartridges can be from different vendors or different brands. For example, cartridges  5601  and  5603  may be from brand A, cartridge  5602  may be from brand B. Cartridge set of cartridges  5601 ,  5602  and  5603  may be provided to user # 1  and user # 2  without knowing user skin condition  5605  or  5610 , whereas the dispense schemes  5608  and  5612  are obtained by: (1) utilizing user data structure  5300  of  FIG. 53 , which is stored in cartridges  5601 ,  5602  and  5603  as specimen information  5621 ,  5622 ,  5623 , and dispenser data structure  5400  of  FIG. 54  which is stored in the information storage component  171 ; (2) correlating skin features grades in data structures  5300  and  5400 ; (3) following the method to use  5407 ,  5411 , and algorithm to match user feature  5409 ,  5413 , of data structures  5400 ; (4) incorporating other relevant information of data structures  5300  and  5400 . 
       FIG. 57  illustrates examples to provide personalized specimen dispensing schemes  5703  and  5705  for the same user based on the unique user data  5701  of the user and the different dispenser data from two different dispenser sets  5710  and  5720 . User device unique user data  5701  and user skin condition  5702  of  FIG. 57  are same as user # 1  device unique user data  5604  and user # 1  skin condition  5605  of  FIG. 56 . Product # 1   5710  cartridge set contains cartridge # 1   5711 , cartridge # 2   5713  and cartridge # 3   5715 , which are same as cartridge # 1   5601 , cartridge # 2   5602  and cartridge # 3   5603  of  FIG. 56 , whereas the specimen information  5712 ,  5714  and  5716  are also same as the specimen information  5621 ,  5622 ,  5623  of  FIG. 56 . The product # 1  cartridge set dispense scheme  5703  and dispensing recipe  5704  are calculated, with the user device unique user data  5701  as shown by  5707 , and with the cartridge specimen information  5712 ,  5714 ,  5716  as shown by  5717 , using same method as the user # 1  cartridge set dispense scheme  5607  and dispensing recipe  5608  are calculated in  FIG. 56 . In other words, product # 1  cartridge set  5710  contains the same cartridges  5601 ,  5602  and  5603  of  FIG. 56 , user of  FIG. 57  is same as user # 1  of  FIG. 56 , and the product # 1  cartridge set dispense scheme  5703  and dispensing recipe  5704  are also same as the user # 1  cartridge set dispense scheme  5607  and dispensing recipe  5608  of  FIG. 56 . 
     Products # 2  cartridge set  5720  contains cartridge # 1   5721  that targets same skin feature “fine lines” as cartridge # 1   5711  of product # 1 , and cartridge # 2   5723  that targets same skin feature “wrinkle” as cartridge # 2   5713  of product # 1 , and cartridge # 3   5725  that targets same skin feature “brown spot” as cartridge # 3   5715  of product # 1 . Cartridges  5721 ,  5723 , and  5725  of product # 2  cartridge set  5720  function similarly as cartridges  5711 ,  5713 , and  5715  of product # 1  cartridge set  5710 . However, cartridge # 2   5723  base grade is Grade 8 per UV as compared to cartridge # 2   5713  base grade is Grade 5 per UV, indicating each UV of cartridge # 2   5723  specimen treats a stronger skin feature of “wrinkle” than each UV of cartridge # 2   5713  specimen, if higher grade is regarded a stronger skin feature of “wrinkle”. Similarly, cartridge # 3   5725  base grade is Grade 2 per UV as compared to cartridge # 3   5715  base grade is Grade 5 per UV, indicating each UV of cartridge # 3   5725  specimen treats a weaker skin feature than each UV of cartridge # 3   5715  specimen. Following same method to obtain product # 1  cartridge set dispense scheme  5703 , product # 2  cartridge set dispense scheme  5705  and dispensing recipe  5706  are calculated with user device unique user data  5701  is acquired as shown by  5708 , and with specimen information  5722  of cartridge # 1   5721 , specimen information  5724  of cartridge # 2   5723 , specimen information  5726  of cartridge # 3   5725  as shown by  5727 . From the specimen information  5722 ,  5724 ,  5726  and user skin condition  5702 , product # 2  cartridge set dispensing recipe  5706  specifies as: 1.0 UV specimen dispensing from cartridge # 1   5721 , 1.0 UV specimen dispensing from cartridge # 2   5723  and 1.0 UV specimen dispensing from cartridge # 3   5725 . 
     In another embodiment, product # 2  may contain different number of cartridges, for example two cartridges, with first cartridge treating both “fine lines” and “wrinkle” features, and second cartridge treating “brown spot”. The combination of cartridges in a product cartridge set has no limitation, whereas the method to produce a dispensing recipe according to user skin condition  5702  and specimen information of the cartridges in the cartridge set is the same, as shown in  FIG. 57 . 
       FIG. 58  illustrates methods to provide personalized specimen composition recipes  5808  and  5812  for two different users, user # 1  and user # 2 , based on the unique user data  5604  and  5609  of each user, and providing personalized dispenser set to the different user with same dispensers that have different compositions.  FIG. 58  is substantially similar to  FIG. 56 , except that the dispense set, or cartridge set, which are composed of cartridge # 1   5801 , cartridge # 2   5802  and cartridge # 3   5803 , is provided to a user with adjusting the composition of the specimen contained within each cartridge of  5801 ,  5802 ,  5803 , such that specimen is dispensed from each cartridge in a pre-determined volume, but having a composition that matches to each user&#39;s own skin care need. Compared to  FIG. 56 ,  FIG. 58  is different in specimen information  5821 ,  5822 ,  5823 , and also different in method to produce cartridge set composition schemes  5807  and  5811 . Cartridges  5801 ,  5802  and  5803  are substantially same as cartridges  5601 ,  5602 ,  5603  in structure, function, components as described in  FIG. 56 , whereas cartridge  5801  targets same skin feature of “fine lines” as cartridge  5601 , cartridge  5802  targets same skin feature of “wrinkle” as cartridge  5602 , and cartridge  5803  targets same skin feature of “brown spots” as cartridge  5603 . 
     Specimen information  5821  describes that cartridge # 1   5801  contains a specimen that is targeted to treat skin feature of “fine line”, with method of use being modifying the Effective Ingredient (“EI”) of specimen contained in cartridge # 1   5801  that is targeted to treat skin feature “fine line” graded as Grade 5 with 100% EI. The skin feature of “fine line” and method of use as in specimen information  5821  may be stored in dispenser data structure same as any of the dispenser data structures  5400 ,  5500 , and  5550  of  FIG. 54 ,  FIG. 55A  and  FIG. 55B , whereas skin feature “fine line” is same as any of the features  5406 ,  5410  of  FIG. 54  or any of the features  5506  and  5516  of  FIG. 55A  and  FIG. 55B , and whereas the reference grade “Grade 5” is same as any of the feature base grades  5408 ,  5412  of  FIG. 54  or any of the feature base grades  5508  and  5518  of  FIG. 55A  and  FIG. 55B , and whereas the method to use, “Grade 5 100% Effective Ingredient (EI)” may be defined as any of the “method to use”  5407 ,  5411  of  FIG. 54 , or any of the method  5507  and  5517  of  FIG. 55A  and  FIG. 55B . Specimen information  5822  describes that cartridge # 2   5802  contains a specimen that is targeted to treat skin feature of “wrinkle”, with method of use being modifying the Effective Ingredient (“EI”) of specimen contained in cartridge # 2   5802  being targeted to treat skin feature “wrinkle” that is graded as Grade 5 with 100% EI. Specimen information  5823  describes that cartridge # 3   5803  contains a specimen that is targeted to treat skin feature of “brown spot”, with method of use being modifying the Effective Ingredient (“EI”) of specimen contained in cartridge # 3   5803  is targeted to treat skin feature “brown spot” that is graded as Grade 5 with 100% EI. 
     Effective ingredient (“EI”) of specimen information  5821 ,  5822 , and  5823  is used as an example to describe the effective elements amount, for example by percentage (%), in the composition of the specimen contained in each of the cartridges  5801 ,  5802  and  5803 , whereas the effective elements function to treat skin features of each of the said specimen information to achieve the skin care purpose of each of the said cartridges. Effective ingredient can be described as a certain amount of weight, for example in units of gram, milligram and microgram, or as a certain volume, for example microliter or milliliter, or as other chemical or physical measurements, of the effective skin care elements contained in a unit volume, or unit weight, or a unit measurement of the specimen contained in each of the cartridges  5801 ,  5802  and  5803 . For example, 100% EI may be representing effective elements being in weight of 1 milligram per microliter of specimen contained in a cartridge, or 1 milligram per liquid of specimen contained in a cartridge, or 1 milligram per dispensing action of specimen from a cartridge, whereas a 60% EI represents effective elements being in weight of 0.6 milligrams per microliter of specimen contained in a cartridge, or 0.6 milligrams per liquid of specimen contained in a cartridge, or 0.6 milligrams per dispensing action of specimen from a cartridge. However, other methods to describe a composition of specimen may also be used, without limitation, to describe EI. Different cartridges  5801 ,  5802 , and  5803  specimen information  5821 ,  5822 ,  5823  may also have different unit volume, unit weigh or unit measurement in definition of EI. 
     Similar as in  FIG. 56 ,  FIG. 58  illustrates that the specimen information  5821  of cartridge # 1   5801 , specimen information  5822  of cartridge # 2   5802  and specimen information  5823  of cartridge # 3   5803  are retrieved from cartridge # 1   5801 , cartridge # 2   5802  and cartridge # 3   5803  as shown by  5813 , and processed together with the unique user data  5604 , as shown by  5647 , from user # 1  dispensing device to produce user # 1  cartridge set composition scheme  5807  that specifies composition recipe  5808  as: 100% EI in specimen of cartridge # 1   5801 , 160% EI in specimen of cartridge # 2   5802  and 40% EI in specimen of cartridge # 3   5803 . Calculation of user # 1  composition recipe  5808  as illustrated in  FIG. 58  is also by a proportional calculation as an example, which ratios each skin feature&#39;s grade as in user # 1  skin condition  5605  relative to the base grade of same skin feature from the corresponding cartridge among the cartridge set. For example, for user # 1 , as “fine lines” grade on user # 1  skin is 5, which is same as the base grade 5 as in the specimen information  5821  of cartridge # 1   5801 , the desired specimen effective ingredient composition in cartridge # 1   5801  is then calculated as (5/5×100% EI)=100% EI; while “wrinkle” grade on user # 1  skin is 8, which is larger than the base grade 5 as in the specimen information  5822  of cartridge # 2   5802 , the desired specimen effective ingredient composition in cartridge # 2   5802  is then calculated as (8/5×100% EI)=160% EI; “Brown spot” grade on user # 1  skin is 2, which is smaller than the base grade 5 as in the specimen information  5823  of cartridge # 3   5803 , the desired specimen effective ingredient composition in cartridge # 3   5803  is then calculated as (2/5×100% EI)=40% EI. Calculation of the composition recipe  5808  from the specimen information  5821 ,  5822 ,  5823  and the user # 1  unique user data  5804  may be performed by any of: information processing component  172  of the control unit  17  in the dispensing device of user # 1 , for example dispensing device  4902  of  FIG. 50 ; a personal computing device  5020  of  FIG. 50 , which may communicate with the dispensing device  4902  as  5037  of  FIG. 50 ; a remote server of a beauty cloud  5040  of  FIG. 50 , which may communicate with the dispensing device  4902  of  FIG. 50  by a data link directly, or through software and data interface via a personal computing device  5020  as  5024  of  FIG. 50 . 
     Following similar calculation method to calculate cartridge set composition recipe  5808 , user # 2  cartridge set composition scheme  5811  with dispensing recipe  5812  may also be calculated from the specimen information  5821 , 5822 , 5823  as shown by  5814  in  FIG. 58 , together with the user # 2  unique user data  5609  as shown by  5691 . According to user # 2  skin condition  5610 , user # 2  cartridge set composition recipe  5812  specifies as: 20% EI in specimen from cartridge # 1   5801 , 40% EI in specimen from cartridge # 2   5802  and 100% EI in specimen from cartridge # 3   5803 . 
     With the same type of cartridges  5801 ,  5802  and  5803 , different than in  FIG. 56 , a same cartridge from cartridge sets of user # 1  and user # 2  do not dispense different amount of specimen, as was done in  FIG. 56 , but rather dispense substantially similar amount of specimen, with specimen having different composition of the effective ingredient for user # 1  and user # 2  as determined by the composition recipes of  5808  and  5812 . In other words, the specimen composition contained in the same type of cartridge may be made different for different user according to each user&#39;s own skin feature and skin condition. The different specimen composition in same type of cartridge for different user may be realized by a process of customized specimen composition pre-filling of the cartridge according to the composition scheme  5808  and  5812 , such that each of the cartridges  5801 ,  5802  and  5803  is filled with a composition according to composition recipe  5808  before being provided to user # 1  to use, and filled with a composition according to recipe  5812  before being provided to user # 2  to use. Alternatively, in the embodiment where at least one of the cartridges  5801 ,  5802  and  5803  may contain sub-compartments, for example similar to cartridge  4313  containing sub-compartments  4301 ,  4311  and  4312  as in  FIG. 43  as well as other relevant components, wherein some sub-compartment contains effective ingredients, and other compartments contain non-effective ingredients, then the effective ingredient percentage value as specified in composition recipes  5808  and  5812  may be realized by built-in valves, flow gates, or in combination of both, such that dispensed effective ingredients and non-effective ingredients may be dispensed in various amount or relative volume to make the final specimen dispensed from the cartridge contain the correct percentage of the effective ingredient following composition recipes  5808  and  5812 . 
     Skin features and their corresponding grades in specimen information  5821 ,  5822 , 5823  as in  FIG. 58  are used as example for illustration purpose, whereas actual skin features and their grades in application are not limited to listed features in  FIG. 58 . Examples given in  FIG. 58  do not limit how composition effective ingredient (EI) is defined for each skin feature. Base grade of specimen information  5821 ,  5822 ,  5823  as in  FIG. 58  does not limit the actual grading scheme that may be used in application. 
     Effective ingredient (EI) in the value of 100% percentage as used in specimen information  5821 ,  5822 ,  5823  in  FIG. 58  may be based on the strength of effective ingredient, or effective elements, in a predetermined physical volume of specimen, for example a microliter, a milliliter, a five-microliter, a drop, or a single dispense action by a dispensing device, or a specimen volume that is designed for treatment of the base grade, i.e. Grade 5 as in  FIG. 58 , of each corresponding skin feature. Effective ingredient (EI) percentage of each of the cartridges  5801 ,  5802  and  5803  may also be adjusted in consideration of existence of other cartridges in the cartridge set. For a first cartridge, whereas existence of other cartridges in a cartridge set, may increase or decrease the skin feature treatment effectiveness of specimen effective ingredient from said first cartridge after specimen from all cartridges are mixed, due to chemical or physical interactions among the specimen, the EI of said first cartridge specimen dispensing will need to adjust accordingly. Alternatively, for a first cartridge, existence of other cartridges in a cartridge set, may increase or decrease the skin feature treatment effectiveness of specimen from said first cartridge after specimen from all cartridges are mixed due to same or similar functional elements in specimen from said first cartridge may also exist in specimen from other cartridges, thus the EI of said given cartridge specimen dispensing will need to adjust accordingly. 
     For a cartridge set, different cartridges can be from different vendors or different brands. For example, cartridges  5801  and  5803  may be from brand A, cartridge  5802  may be from brand B. Cartridge set of cartridges  5801 ,  5802  and  5803  may be provided to user # 1  and user # 2  after knowing user skin condition  5605  or  5610  and implementing the composition recipes  5808  and  5812  to the cartridges  5801 ,  5802  and  5803 , whereas the composition recipes  5808  and  5812  are obtained by: (1) utilizing user data structure  5300  of  FIG. 53  and dispenser data structure  5400  of  FIG. 54 ; (2) correlating skin features grades in data structures  5300  and  5400 ; (3) following the method to use and algorithm of data structures  5400 ; (4) incorporating other relevant information of data structures  5300  and  5400 . 
     In  FIG. 58 , as cartridges  5801 ,  5802  and  5803  have the specimen contained therein being adjusted of the composition to match to each individual user, user # 1  and user # 2 , through a possible refill or order with customized compositions recipes  5808  and  5812 , cartridges  5801 ,  5802  and  5803  may not have an embedded data storage device  142  of  FIG. 2 , as all necessary information required to match to user&#39;s skin care need is already included in the various specimen composition, whereas a dispensing device  10  of  FIG. 2  only need to dispense the specimen from cartridges  5801 ,  5802  and  5803  in fixed volume values and final composition of the dispensed specimen will be automatically matching to the each user&#39;s own skin condition.

       FIG. 62  illustrates data communication methods between computing devices and a dispensing device through charging coils. For the data communications  5037  and  5038  between a dispensing device  4902 , and skin analysis step  5010  or a personal computing device  5020 , as in  FIG. 50 , or for the data links  5935 ,  5938  and  5939  between a dispensing device  5931 , and a computer  5932 , or a mobile phone  5933 , or a remoter server  5834 , as in  FIG. 59 , the data communications or data links may be accomplished through the dispensing device, illustrated as device  10  in  FIG. 62 , communicating with a wireless inductive charger  6201  through inductive coupling between a set of charging coils  6206  and  6208 . Device  10  of  FIG. 62  is same as in  FIG. 2 , except the device  10  of  FIG. 62  contains a charging coil  6206  that is connected to the control unit  17  by electrical connection  6205 . The dispensing device  10  is placed in close proximity to a charger  6201 , for example with a gap between the opposing surfaces of the device  10  and charger  6201  being less than 5 millimeters, whereas the charger  6201  has another charger circuit  6204  that connects to another charging coil  6208  through electrical connection  6209 . In a normal charging operation, the device  10  placed in close proximity to the charger  6201 , such that the charging coils  6206  and  6208  are inductively coupled. The charger unit  6204  drives alternating current through the coil  6208  by the electrical connection  6209 . Said alternating current in coil  6208  produces alternating electromagnetic field that inductively couples to the coil  6206  through the external bodies of both the charger  6201  and device  10  and generates alternating voltage or current in the coil  6206 , whereas the generated alternating voltage or current couples to the control unit  17  through electrical connection  6205  and achieves charging the battery devices that is part of, or connected to, the control unit  17 . Inductive charging of device  10  battery device by the charger  6201  through the coils  6206  and  6208  may be achieved by an alternating current applied to the coil  6208  with a first frequency. 
     In addition to charging function, coils  6206  and  6208  may also provide means for digital data communication to achieve data communications  5037  and  5038  of  FIG. 50 , or the data links  5935 ,  5938  and  5939  of  FIG. 59 . Control unit  17  and charger unit  6204  may also communicate analog or digital data between each other, for example user data structure  5300  of  FIG. 53 , or dispenser data structure  5400  of  FIG. 54 , or any wireless communication protocol similar to 802.11, Bluetooth, TCP/IP, and transmit the data protocol from device  10 , by inductive coupling between coil  6206  and coil  6208 , whereas said analog or digital data transmission is performed by modulating an alternating electrical voltage or current signal with a second frequency. The second frequency is substantially different than the first frequency, for example first frequency may be smaller than 1 MHz that achieves maximum power transfer through inductive coupling of the coils  6206  and  6208 , and second frequency may be higher than 10 MHz that is suitable for data transfer through the coils  6206  and  6208  whereas the coils  6206  and  6208  function as transmitting and receiving antennas of a wireless communication in RF frequencies. During operation, charging and data transfer between the coils  6206  and  6208  may be separately operated, whereas charging at first frequency and data transfer at second frequency are always performed separately, and only a single frequency, first frequency or second frequency, voltage or current signal is produced on the coils  6206  and  6208  at any instant time. Alternatively, charging and data transfer between the coils  6206  and  6208  may be concurrent, whereas charging at first frequency and data transfer at second frequency are performed simultaneously, whereas the signal from the two frequencies are modulated in a single analog signal, for example similar to the frequency-modulated (FM) radio signal or GSM signals in mobile phone communication, whereas the analog signal is transmitted through the coils  6206  and  6208 . Each of the control unit  17  and charger unit  6204  have embedded circuits that can separate the signals from the first and second frequencies by frequency based filtering techniques, whereas the first frequency signal is separated and directed to the charging circuit of control unit  17  for charging the device  10  battery, while second frequency signal is separated and directed to a data de-modulation circuit where the transmitted data are recovered from second frequency signal.
