Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to U.S. Provisional Patent Application No. 62/765,592 filed Aug. 31, 2018, the entirety of which is incorporated by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to a multi-functional shower head attachment device with suction and pressure capabilities, and, more particularly, relates to a multi-functional shower head attachment device that effectively and efficiently enables users to induce a pressurized flow of liquid or suction with handheld device selectively removably couplable to a conventional shower head or plumbing fixture. 
     BACKGROUND OF THE INVENTION 
     Typically, taking a shower involves lathering with soap and then rinsing off with a showerhead that has controllable water temperature. It is also possible to utilize a multifunction shower head that can discharge water in any of many different spray patterns, such as a fine spray, a coarse spray, or a pulsating spray. Of course, many other spray patterns may also be provided. Such shower heads are available in both wall-mounted and hand-held models. Therefore, the same internal mechanism should be usable in either model. However, showerheads can only discharge water as they don&#39;t have the capacity to also create a sucking effect at the nozzle head. 
     Therefore, a need exists to overcome the problems with the prior art as discussed above. 
     SUMMARY OF THE INVENTION 
     The invention provides a multi-functional shower head attachment device with suction and pressure capabilities that overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type and that effectively and efficiently enables users to induce a pressurized flow of liquid or suction with handheld device selectively removably couplable to a conventional shower head or plumbing fixture. The device includes a housing containing a fluid transport network that is selectively manipulated along a valve translation path to selectively induce a negative pressure vacuum, and a pressurized discharge of driving fluid through a water ejector configuration. The vacuum is generated as the pressurized driving fluid is diverted through a first configuration of conduits, past a venturi channel and through a secondary exit port; thereby creating the vacuum through adjacent, fluidly coupled conduits. The pressurized fluid discharge is generated as the pressurized driving fluid is diverted directly through a series of conduits to an exit port. 
     The housing is coupled to a handheld suction and pressure housing assembly through a flexible unit conduit. The generated vacuum and the pressurized fluid discharge create suction and pressurized fluid discharge, respectively, through a nozzle in the handheld suction and pressure housing assembly. Through the nozzle, a user can wash, shower, remove acne/oils, and perform other cleaning and personal hygiene functions with both suction and pressurized driving fluid discharge. 
     With the foregoing and other objects in view, there is provided, in accordance with the invention, a multi-functional plumbing fixture attachment device with suction and pressure capability that includes a housing defining an intake port, an exit port, a secondary exit port, and a valve port. 
     The device further includes a fluid transport network that is disposed within the housing. The fluid transport network has a first conduit coupled to the intake port of the housing. The fluid transport network also has a second conduit coupled to the exit port of the housing. 
     Additionally, the fluid transport network has a third conduit coupled to the exit port of the housing. The fluid transport network also has a fourth conduit coupled to the secondary exit port of the housing. In one embodiment, the fourth conduit forms a venturi channel. The fluid transport network also has a fifth conduit fluidly coupled to the fourth conduit at the venturi channel. 
     In some embodiments, the device comprises a valve housing disposed within and coupled to the housing. The valve housing has a valve stem extending through the valve port and coupled to a valve lever. The valve stem has an internal fluid bore. The valve stem further has a secondary internal fluid bore defined thereon that is structurally and fluidly independent from the internal fluid bore. 
     In one possible embodiment, the valve stem is operably configured to selectively translate in a valve translation path. Through this translation path, the valve stem is operably configured to have a vacuum position along the valve translation path with the first, second, third, fourth, and fifth conduits fluidly coupled to one another, the internal fluid bore fluidly uncoupled to the first, second, third, fourth, and fifth conduits. The vacuum position is also operably configured to generate a vacuum within the second conduit, the secondary internal fluid bore, and the fifth conduit.

     In some embodiments, the device includes a fluid source that is in fluid communication and selectively removably couplable with the intake port. The fluid source is operable to discharge a pressurized driving fluid through the intake port. In this manner, in the vacuum position, the pressurized driving fluid is diverted through the venturi channel in the fourth conduit, and through the secondary exit port  108 . Thus, the driving fluid passing through the venturi channel creates the vacuum within the second conduit, the secondary internal fluid bore, and the fifth conduit. Also, in the pressurized discharge position, the pressurized driving fluid is diverted through the first conduit, the internal fluid bore, and the third conduit, whereby the pressurized driving fluid discharges through the exit port. 
     The device also includes a handheld suction and pressure housing assembly having a housing and a nozzle coupled to the housing. The nozzle defines a nozzle opening. Also, the nozzle is fluidly coupled to the exit port of the housing. 
     In accordance with another feature, the secondary internal fluid bore is structurally and fluidly independent from the internal fluid bore by a valve wall. 
     In accordance with another feature, the valve stem is operably configured to selectively translate within the valve housing and in a circular valve translation path up to 90°. 
     In accordance with another feature, the valve stem further includes an upper end, a lower end opposing the upper end of the valve stem, a left side, a right side opposing the left side of the valve stem, a left end, and a right end opposing the left end of the valve stem, and a stem length separating the left and right ends of the valve stem. 
     In accordance with another feature, the valve stem also comprises an outer surface surrounding the perimeter of the valve stem along the stem length and defining a first enclosed aperture disposed on the upper end of the valve stem, a second enclosed aperture disposed on the lower end of the valve stem and aligned with the first enclosed aperture, a third enclosed aperture disposed on the left side of the valve stem, a fourth enclosed aperture disposed on the right side of the valve stem, and a fifth enclosed aperture disposed on the lower end of the valve stem. 
     In another aspect of the present invention, the device also comprises a flexible unit conduit coupling the housing of the handheld suction and pressure housing assembly, and the valve housing. 
     In another aspect of the present invention, the vacuum position along the valve translation path includes the fourth enclosed aperture fluidly uncoupled to the first, second, third, fourth, and fifth conduits and the flexible unit conduit and the fifth enclosed aperture and the secondary internal fluid bore fluidly coupled to the first, second, third, fourth, and fifth conduits and the flexible unit conduit. 
     In another aspect of the present invention, the pressurized discharge position along the valve translation path includes the first and fourth enclosed apertures and the internal fluid bore fluidly coupled to the first, second, and third conduits and the flexible unit conduit and the fifth enclosed aperture and the secondary internal fluid bore fluidly uncoupled to the first, second, third, fourth, and fifth conduits and the flexible unit conduit. 
     In another aspect of the present invention, the conduits of the fluid transport conduct network include at least one of the following: at least one straight tube coupled to the housing of the housing, at least one elbow tube coupled to the housing, and a spout coupled to the valve housing. 
     In another aspect of the present invention, when the valve translation path is in the vacuum position, the nozzle opening is operable to suck air into the housing of the handheld suction and pressure housing assembly and discharges the air through the secondary exit port. 
     In accordance with another feature, when the valve translation path is in the pressurized discharge position, the nozzle opening is operable to discharge the pressurized driving fluid. 
     In accordance with another feature, the nozzle opening is fluidly coupled to at least one secondary attachment.

     DETAILED DESCRIPTION 
     While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. 
     The present invention provides a novel and efficient multi-functional shower head attachment device  100  that overcomes the hereinafore-mentioned disadvantages of the heretofore-known devices and methods of this general type and that effectively and efficiently enables users to induce a pressurized flow of liquid or suction with handheld device selectively removably couplable to a fluid inlet  124 , such as a conventional shower head or plumbing fixture. 
     Embodiments of the invention provide a housing  102  containing a valve stem  214  that includes a unique fluid transport network of conduits  202 ,  204 ,  206 ,  208 ,  210  and fluid bores  216 ,  218 . The valve stem  214  is manipulated along a valve translation path  700  to selectively induce a negative pressure vacuum, and a pressurized discharge of driving fluid  304 . The vacuum is generated as the pressurized driving fluid  304  is diverted through a first configuration of conduits, past a venturi channel  302 , and through a secondary exit port  108 ; thereby creating the vacuum through adjacent, fluidly coupled conduits. The pressurized fluid discharge is generated as the pressurized driving fluid  304  is diverted directly through a series of conduits to an exit port  106 . 
     In addition, embodiments of the invention provide a handheld suction and pressure housing assembly  114  that is in fluid communication with the housing and valve stem, through a flexible unit conduit  116 . The vacuum, and the pressurized fluid discharge, work to create suction and/or pressurized fluid discharge, respectively, through a nozzle  120  in the suction and pressure housing assembly  114 . Through the nozzle  120 , a user can wash, shower, remove acne/oils, and perform other cleaning and personal hygiene functions by selectively switching between the vacuum position  300  and the pressurized driving fluid discharge position  400 . The capacity to switch between the vacuum position and the pressurized fluid discharge position is possible through a tubular valve switch, such as a water ejector. Further, the device  100  requires only a pressurized water source, such as a shower head or sink faucet to operate. 
     Referring now to  FIG. 1 , one embodiment of the present invention is shown in a perspective view.  FIG. 1  shows several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. The first example of a multi-functional shower head attachment device  100 , hereafter “device  100 ” includes a housing  102  that is shaped and dimensioned to couple to a fluid inlet, such as a showerhead, faucet, water outlet, and other plumbing fixture known in the art. The housing  102  is defined by an intake port  104  that couples with the fluid inlet  124 . The housing also has a bottom end through which an exit port  106 , a secondary exit port  108 , and a valve port  110  form. These lower ports  106 ,  108 ,  110  provide outlets that are in fluid communication with conduits, described below. 
     The device  100  further includes a fluid transport network  200  that is disposed within the housing  102 . The fluid transport network  200  includes a series of conduits  202 ,  204 ,  206 ,  208 ,  210  and fluid bores  216 ,  218  that are coupled together to carry a pressurized driving fluid  304  and/or a negative pressure to and from the ports  106 ,  108 ,  110 . The configuration of the conduits and fluid bores is selectively reconfigurable to regulate between a vacuum position  300  that creates a vacuum through the secondary exit port  108 , and a pressurized discharge position  400  that creates a pressurized discharge of a driving fluid  304  through the exit port  106 . Since the suction and pressure housing assembly  114  is in fluid communication with the fluid transport network  200 , the suction and pressurized driving fluid are experienced at the nozzle  120  ( FIGS. 9-12 ). 
     In one non-limiting embodiment, the conduits and fluid bores that constitute the fluid transport network  200  include: at least one straight tube that couples to the housing of the housing; at least one elbow tube couples to the housing; and a spout that couples to the valve housing  212 . However, different types of plumbing connectors and adapters known in the art may also be used. As shown in  FIGS. 3-4  the conduits are positioned to carry air and driving fluid  304  to the respective ports for effective sucking and pressurized fluid discharge. 
     Looking now at  FIG. 2 , the fluid transport network  200  includes a first conduit  202  that is coupled to the intake port  104  of the housing  102 . The first conduit  202  is the initial entry point for the driving fluid  304 , i.e., water from showerhead. Continuing with the network of conduits, the fluid transport network  200  also has a second conduit  204  that is coupled to the exit port  106  of the housing  102 . Additionally, the fluid transport network  200  has a third conduit  206  coupled to the exit port  106  of the housing  102 . 
     As  FIG. 3  illustrates, the fluid transport network  200  also has a fourth conduit  208  coupled to the secondary exit port  108  of the housing  102 . In one embodiment, the fourth conduit forms a venturi channel  302 , utilized to create the negative air pressure effect (sucking) through the conduits  204 ,  218 ,  210 . The venturi channel  302  is defined as a restriction in the diameter of the fourth conduit  208 . The fluid transport network  200  also has a fifth conduit  210  that is fluidly coupled to the fourth conduit  208  at the venturi channel  302 . The vacuum effect forms in the fifth conduit  210 , and all other conduits in fluid communication therewith. The vacuum is also formed through the exit port  106  and the nozzle  120  of the suction and pressure housing assembly  114 , which is in fluid communication with the fluid transport network  200 . Thus, the driving fluid  304  enters the first conduit, flows through the fourth conduit and the venturi channel  302 , before exiting the secondary exit port  108  as air bubbles and sucked residue  306  entering the fluid transport network  200  through the exit port  106 . 
     Those skilled in the art will recognize that a venturi creates a constriction within the fourth conduit  208  that varies the flow characteristics of the driving fluid  304  flowing therethrough. Thus, as the velocity of the driving fluid  304  increases there is a consequential drop in pressure in the fifth conduit  210  and all other conduits in fluid communication therewith. For purposes of creating a vacuum in the fluid transport network  200 , the drop in pressure occurs in the second conduit  204 , the secondary internal fluid bore, and the fifth conduit  210 , as described below. 
     In some embodiments, the device  100  comprises a valve housing  212  that is disposed within and coupled to the housing  102 . The valve housing  212  comprises a valve stem  214  that extends through the valve port  110  (see  FIG. 2 ). The valve stem  214  is coupled to a valve lever  112  that can be manipulated by the hands to rotate along a valve translational path  700 . The valve stem  214 , through the valve lever  112 , is operably configured to enable selective translation in a circular valve translation path  700  up to 90° in both directions. The stem  214  may be rotatably coupled to the valve housing  212  with one or more polymeric O-rings to facilitate in preventing fluid loss and leakage. The stem  214  may also be rotatably coupled to the valve housing  212  with one or more bearings to facilitate in easily rotating the valve stem  214 . For example, the valve stem  214  may be rotated 90° in a first direction (clockwise) to configure the conduits into the vacuum position  300 . Then, the valve stem  214  can be turned 90° in an opposite second direction (counterclockwise) to configure the conduits into the pressurized discharge position  400 . However, in other embodiments, different valve stem manipulation mechanisms and ranges of rotation can be used. 
     In this manner, when the valve translation path  700  is in the vacuum position  300 , the nozzle opening is operable to suck air into the housing of the handheld suction and pressure housing assembly  114  and discharges the air through the secondary exit port  108 . And when the valve translation path is in the pressurized discharge position  400 , the nozzle opening  122  of the suction and pressure housing assembly  114  discharges the pressurized driving fluid  304 . As  FIGS. 5-6  illustrate, the valve stem  214  has an internal fluid bore  216  that can be selectively opened and closed into fluid communication with the intake port and the connected conduits and ports. The valve stem  214  further has a secondary internal fluid bore  218  defined thereon that is structurally and fluidly independent from the internal fluid bore  216 . The secondary internal fluid bore  218  can also be selectively controlled to opened and closed positions in relation to adjacently connected conduits and ports. 
     In one possible embodiment, the valve stem  214  is moved along a valve translation path  700 , which can include the 90° rotation discussed above. Through this translation path, the valve stem  214  is operably moved to a vacuum position  300  along the valve translation path  700  with the first, second, third, fourth, and fifth conduits fluidly coupled to one another, and the internal fluid bore  216  fluidly uncoupled to the first, second, third, fourth, and fifth conduits. 
     As  FIG. 3  shows, the second conduit, the secondary internal fluid bore, and the fifth conduit are in fluid communication. The venturi channel  302  in the fourth conduit accelerates the driving fluid  304  to create the vacuum effect in these connected conduits and bore. Thus, the vacuum position  300  is configured to generate a vacuum within the second conduit  204 , the secondary internal fluid bore, and the fifth conduit  210 , and the exit port, which is in fluid communication with the suction and pressure housing assembly  114 .  FIG. 5  also shows a sectioned side view of the conduits and fluid bores configured into the vacuum position  300 . Here, the conduits are configured such that the first, second, third, fourth, and fifth conduits fluidly coupled to one another, and the internal fluid bore  216  fluidly uncoupled to the first, second, third, fourth, and fifth conduits. 
     Turning now to  FIG. 4 , the translation path  700  can include reconfiguring the conduits such that the valve stem  214  is moved to achieve a pressurized discharge position  400 . In the pressurized discharge position  400 , the internal fluid bore, and the first, second, and third conduits are fluidly coupled to one another; and fluidly uncoupled to the fourth and fifth conduits. This works to close the fourth and fifth conduits. Thus, the driving fluid  304  is forced through the exit port  106 , and subsequently through the flexible unit conduit  116  to the suction and pressure housing assembly  114  for discharge onto the skin/body.  FIG. 6  illustrates a sectioned side view of the conduits and fluid bores configured into the pressurized discharge position  400 . As shown, the internal fluid bore, and the first, second, and third conduits are fluidly coupled to one another; and fluidly uncoupled to the fourth and fifth conduits. 
     Looking at a sectioned side view of the valve stem  214 ,  FIG. 7  shows that the valve stem  214  comprises an upper end  702 , a lower end  704  opposing the upper end  702  of the valve stem  214 , a left side  706 , a right side  800  opposing the left side of the valve stem  214  ( FIG. 8 ). The valve stem  214  is also defined by a left end  708 , and a right end  710  opposing the left end  708  of the valve stem  214 . The valve stem  214  is also defined by a stem length separating the left and right ends  708 ,  710  of the valve stem  214 . 
     Looking now at  FIG. 8 , the valve stem also comprises an outer surface  712  surrounding the perimeter of the valve stem  214  along the stem length and defining a first enclosed aperture  714  disposed on the upper end  702  of the valve stem  214 , a second enclosed aperture  1102  disposed on the lower end  704  of the valve stem  214  and aligned with the first enclosed aperture  714 , a third enclosed aperture  716  disposed on the left side  702  of the valve stem  214 , a fourth enclosed aperture  1104  disposed on the right side  800  of the valve stem  214 , and a fifth enclosed aperture  718  disposed on the lower end  704  of the valve stem  214 . 
     In some embodiments, the device  100  includes a fluid source (represented by numeral  128 ) that is in fluid communication and selectively removably couplable with the intake port  104  ( FIG. 2 ). The fluid source  128  is operable to discharge a pressurized driving fluid  304  through the intake port. In this manner, in the vacuum position  300 , the pressurized driving fluid  304  is diverted through the venturi channel  302  in the fourth conduit, and through the secondary exit port  108 . Thus, when the valve translation path  700  is in the vacuum position  300 , the nozzle opening  122  is operable to suck air into the housing of the handheld suction and pressure housing assembly  114  and discharges the air through the secondary exit port  108 . The driving fluid  304  passing through the venturi channel  302  creates the vacuum within the second conduit, the secondary internal fluid bore, and the fifth conduit. Also, in the pressurized discharge position  400 , the pressurized driving fluid  304  is diverted through the first conduit, the internal fluid bore, and the third conduit, whereby the pressurized driving fluid  304  discharges through the exit port  106 . As seen in  FIGS. 1-2 , the device  100  may also include a head port  130  operably configured to directly couple with a conventional shower head (not shown), e.g., through a threaded attachment like other ports shown in the figures. To selectively divert the fluid source, the head  132  of the device  100  may include a push valve  134  operably configured to translate and divert flow to the head port  130  or the fluid transport network  200 . 
     In regard to the fluid transport network  200 , the vacuum position  300  along the valve translation path  700  includes the fourth enclosed aperture  1104  fluidly uncoupled to the first, second, third, fourth, and fifth conduits. The vacuum position  300  also involves the flexible unit conduit and the fifth enclosed aperture  1018  and the secondary internal fluid bore  218  fluidly coupled to the first, second, third, fourth, and fifth conduits and the flexible unit conduit. Conversely, the pressurized discharge position  400  along the valve translation path  700  includes the first and fourth enclosed apertures  1014 ,  1104  and the internal fluid bore  216  fluidly coupled to the first, second, and third conduits and the flexible unit conduit and the fifth enclosed aperture  1018  and the secondary internal fluid bore  218  fluidly uncoupled to the first, second, third, fourth, and fifth conduits and the flexible unit conduit. Thus, when the valve translation path is in the pressurized discharge position  400 , the nozzle opening is operable to discharge the pressurized driving fluid  304 . 
     Turning now to  FIG. 9 , the device  100  also includes a handheld suction and pressure housing assembly  114  that works in conjunction with the housing  102  and valve stem  214 , discussed above. The suction and pressure housing assembly  114  is the component that a user grips while vacuuming oils/acne/pimples from the skin, and also while spraying the skin with pressurized driving fluid  304 , i.e., water. The suction and pressure housing assembly  114  is in direct fluid communication with the valve housing. The suction and pressure housing assembly  114  includes a nozzle  120  that facilitates in inducing the vacuum or direct fluid pressure based on the position  300 ,  400  of the valve stem  214 . In one embodiment, the handheld suction and pressure housing assembly  114  may also include a finger-sized hole, e.g., approximately 0.2-0.7 inches, defined thereon that is fluidly coupled to the nozzle  120  and is configured to enable the user to cover the finger-sized hole to selectively increase or decrease the vacuum induced through the nozzle  120 . The secondary exit port  108  may also be finger-sized to enable the user to cover the finger-sized hole to selectively increase or decrease the vacuum. 
     As  FIG. 10  illustrates, the handheld suction and pressure housing assembly  114  comprises a housing  118  that is sized and dimensioned to fit into the hand. This configuration may include a short, tubular component with smooth contours adapted to fit in a standard human hand. A control switch  126  is operable on the housing  118 . The control switch  126  is configured to be in communication with the valve stem  214  to regulate powering on and off the assembly  114 . The control switch  126  may also be used to control multiple spray patterns, such as a fine spray, a coarse spray, or a pulsating spray from the nozzle  120 . The control switch  126  is electrically coupled to a power source, e.g., one or more lithium-ion batteries, that may also be electrically and communicatively coupled to a controller, e.g., a PCB board, that may be coupled to one or more LEDs or other electrical devices described herein. 
     In some embodiments, a flexible unit conduit  116  is configured to couple the housing  118  of the suction and pressure housing assembly  114  to the valve housing  212  that contains the valve stem  214 . In one non-limiting embodiment, the flexible unit conduit  116  is a coiled metal tube that is sufficiently flexible to enable positioning the handheld suction and pressure housing assembly  114  along the skin and parts of the body. In some embodiments, the valve housing  212  has a nozzle  120  coupled thereto. A nozzle coupling mechanism  900 , such as a spring, may be used to affix the nozzle to the opening of the valve housing  212 . However, in other embodiments, the nozzle coupling mechanism  900  may include a threaded bolt or a snap-fit mechanism. 
       FIG. 11  is a perspective view of the handheld suction and pressure housing assembly disconnected from the flexible unit conduit. In some embodiments, the nozzle  120  is fluidly coupled to the exit port  106  of the housing  102  through the flexible unit conduit  116 . In this manner, the vacuum effect enables sucking through the nozzle. This can be useful for sucking blackheads and other undesirable objects from the skin. Also, the pressurized fluid is discharged through the nozzle  120 , as the fluid flows through the exit port  106  to the nozzle  120 . In one embodiment, the nozzle  120  defines a nozzle opening  122 . The nozzle opening  122  may be configured to enable selective discharge types. For example, a wide spray can be changed to a narrow, intense stream of driving fluid  304 . As  FIG. 12  illustrates, the nozzle opening  122  is fluidly coupled to at least one secondary attachment  1200 . In some embodiments, the secondary attachment  1200  may include, without limitation, a light source, a massage pulse nozzle, a brush, a pick, and other personal hygiene tools known in the art. 
     In operation, the intake port is coupled to a fluid intake, such as a plumbing fixture for a shower head. The driving fluid, which may include water, is opened through the plumbing components to generate a pressurized driving fluid through the first conduit. The valve stem  214  is rotated along the translational path  700  to a vacuum position  300 . The pressurized driving fluid  304  is diverted through the venturi channel  302  through the fourth conduit, and through the secondary exit port  108 . Thus, when the valve translation path  700  is in the vacuum position  300 , the nozzle opening is operable to suck air into the housing of the handheld suction and pressure housing assembly  114  and discharges the air through the secondary exit port  108 . 
     From the vacuum position, the user may then grab the handheld suction and pressure housing assembly  114 , placing the nozzle along the skin to remove blackheads or other debris from the skin/body. As the suction occurs through the fourth conduit  208 , air bubbles and residue are discharged through the secondary exit port  108 . Next, the valve stem  214  is rotated along the translational path  700  to a pressurized fluid position  400 . The pressurized driving fluid  304  is diverted through the first conduit, the internal fluid bore, and the third conduit, whereby the pressurized driving fluid  304  discharges through the exit port  106 . The user may then grab the handheld suction and pressure housing assembly  114  to spray fluid onto the skin. 
     Various modifications and additions can be made to the exemplary embodiments discussed without departing from the scope of the present disclosure. For example, while the embodiments described above refer to particular features, the scope of this disclosure also includes embodiments having different combinations of features and embodiments that do not include all of the above described features.
