Description:
CROSS REFERENCE TO RELATED APPLICATION  
       [0001]    This application is a continuation-in-part of a prior U.S. application with Ser. No. 10/043,928, filed on Jan. 9, 2002 and entitled “MULTIMEDIA AND SCENT STORAGE MEDIUM AND PLAYBACK APPARATUS HAVING ELECTROSTATIC SCENT RELEASE FOR USING SAME”, which is hereby incorporated by reference in its entirety as if filly restated herein. 
     
    
     
       FIELD OF THE INVENTION  
         [0002]    The present invention concerns scent-bearing and multimedia medium for use in conjunction with multimedia systems having scent-dispersing capability, and in particular to new scent-bearing cartridges for use with a hand-held or miniature multimedia playback system.  
         BACKGROUND OF THE INVENTION  
         [0003]    The present invention concerns scent storage and release systems that are used to create olfactory sensations in, e.g., aromatherapy. These systems can be used either separately or in combination with multimedia playback systems. When scent storage and release systems are used in combination with multimedia playback systems, an immersive multi-sensory experience can be created. Such multi-sensory experiences are attractive not only for entertainment purposes, but also for therapeutic purposes.  
           [0004]    The prior art concerning such scent storage and release systems, particularly with reference to those systems intended for use with current and contemplated multimedia systems, are best by a number of limitations. In particular, little thought has been given to how a scent storage and release system can be integrated into a hand-held or miniature multimedia playback system.  
           [0005]    This is true on two counts. First, users of such systems will have certain expectations about how such systems should operate due to their experience with such hand-held or miniature multimedia devices, e.g., mobile phone, personal digital assistant, portable computing devices, and wearable miniature multimedia devices.  
           [0006]    The best of these systems give users a high degree of mobility in assessing multimedia experience through portable and miniature design features. With these systems the user can customize multimedia playback and interact with a remote signal source (e.g. internet, server, LAN, or wireless LAN) in a wireless fashion. This provides for a desirable customized and assessable multimedia experience.  
           [0007]    In contrast, scent storage and release systems that may be used in combination with multimedia sources show no appreciation of this desirable feature. For example, U.S. Pat. No. 6,053,738 to Jr. Ivey describes methods for controlling the creation of olfactory stimuli. Although it suggests that its methods may be used in combination with a multimedia source, there is no description about how this can be accomplished. In particular, there is no description of how multiple scent storage units and scent release system can be integrated or manufactured in a compact fashion. Further, there is no description of how to coordinated the arrangement of multiple scent storage units with the multiple scent release system so that various scent can be retrieved for future use in repeating the multiple scent release operation.  
           [0008]    A second problem concerns the physical integration of scent storage and release systems with known or contemplated hand-held or miniature multimedia playback systems. This concerns both scent recovery and release systems for use in recovering and releasing scents stored in the scent storage media, and the scent storage media itself. There is little or no appreciation of the need to design scent storage media so that they can be easily combined with multimedia storage media either in an integrated package, or in separate, but combinable, packages.  
           [0009]    In particular, there are well-known current and contemplated multimedia storage formats. For example, there is the encapsulated Type II DVD RAM format in which an optical DVD storage media is encapsulated in a rugged housing. There are also the standard DVD and CD optical disk formats. There has been little or no effort made in seeking to integrate scent storage media with these well-known multimedia storage formats. Such an heretofore unknown combination would provide a user with a compact and easy-to-use multimedia and scent storage medium that would be capable in combination with a scent release and multimedia playback system of creating a complete multimedia experience.  
           [0010]    There also is a lack of appreciation of the need to design scent release technologies that can be used in close proximity to sensitive electronic equipment. Scents often are volatile oil-like substances that unless properly handled can hinder the fault-free operation of a scent recovery and multimedia playback system.  
           [0011]    Improved scent release technologies are therefore desired. Suitable hardware for applying appropriate scent release technologies, e.g., electrostatic scent release, have not been developed heretofore. These scent release technologies must be designed to operate in conjunction with current and contemplated micro-machinery technologies in order to take advantage of having technically efficient, cost effective, widespread consumer applicability and appeal. Presently, there are no known designs suitable for combining electrostatic scent release with micro-machinery technology.  
           [0012]    Another problem concerns the efficient storage and release of scents, fragrances, flavors, aromas and therapeutic agents so that the minimum amount of these often expensive compounds can be used to maximum effect. One aspect of this problem concerns the efficient storage of scent between scent release operations so that the characteristic smell or scent of the substance is preserved. In addition, as these compounds often are volatile, they will be escape over time unless retained in an effective manner.  
           [0013]    From the user&#39;s perspective, a number of limitations have been identified in current scent release technology intended for use with a hand-held or miniature device. In particular, current scent release systems make no provision for allowing a user to control the smell range by a user-specified scent release range control means. In the audio and video field, users have been given a high degree of control over personal space issue. Users do not have this level of control over scent release intended to apply with a hand-held or miniature device.  
           [0014]    Thus, those familiar with the prior art desire several heretofore unknown and uncontemplated systems and methods to resolve the current limitations in the prior art. In particular, those skilled in the art desire a scent disk or cartridge design incorporating scent release units that can be easily combined with current and contemplated hand-held device or wireless applications. In particular, the most desirable scent cartridge design should be easily integrated into hand-held-device-like module. Such a scent cartridge and scent recovery/release system design could be easily integrated into the housing of the hand-held device, providing for a single, easy-to-use scent- and multimedia bearing medium that, in conjunction with a multimedia playback system, is capable of creating an immersive multimedia experience, including visual, auditory and olfactory elements.  
           [0015]    Those skilled in the art also desire new scent release technologies that improve the performance of scent release systems intended for use in multimedia environments. Particularly desirable are systems that preserve the inherent scent characteristics of the fragrance, aroma or flavor to be released, and in no way cross-contaminate them as part of the scent release process. Also desired are scent release operations that heighten the impact of the scent or fragrance by proper neutralizing operation between each different scent releasing, so that a user experiences encounters a heightened, improved olfactory sensation. The desired scent release technology also would efficiently store the fragrance, aroma or flavor between release operations, thereby not only reducing the need to replace the scent disk or cartridge but also creating unintended residual smell due to the evaporation of scent.  
           [0016]    In summary, those skilled in the art desire a scent disk or cartridge design that is as easy- to-use, inexpensive, rugged and effective as other powerful mobile-device and multimedia technologies.

The method comprises the following steps: receiving an input command from a user to initiate scent release through the communication port of the hand-held device; recovering digital scent release and multimedia playback control information corresponding to the user input command from a user; interpreting the identity, time, and duration of scent release reflected in the digital scent release and multimedia playback control information; and releasing the proper scents at the proper time and for the proper duration from the scent cartridge . In one variant of the third embodiment, an additional step in which scent to be released is ionized or vaporized occurs. In another variant of the method of the third preferred embodiment, several scents may be released simultaneously for similar or differing durations. In further variants, an additional step comprising a scent neutralizing operation is added to the method. During the scent neutralizing step, a scent neutralizing agent, for example, ozone is released. The step would follow the release of one scent and precede the release of another.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0087]    A scent-bearing disk or cartridge made in accordance with the second and third preferred embodiments of the present invention is depicted in perspective, top and side views in FIG. 1. The hand-held device integrated scent-bearing cartridge  001  is depicted attached to a hand-held device  002 . The hand-held device is shown to better advantage in FIG. 2, which depicts the communication and power supply port  003  of the hand-held device detached so the hand-held device integrated scent-bearing disk or cartridge can be removed or reinserted.  
         [0088]    FIGS.  3  depicts variants of the first preferred embodiment in which the hand-held device integrated scent-bearing cartridge  001  are combined in various ways about the periphery of the hand-held device  002 .  
         [0089]    A complete scent-bearing cartridge  005  having scent release micro-pumping units made in accordance with the first preferred embodiment of the present invention is shown in FIG. 4A. The scent-bearing cartridge  005  shown in FIG. 4A comprises a plurality of separate scent release micro-pumping units  030 , each of which is contained in a three-dimensional sector of the disk. The scent release micro-pumping units  030  has a scent conducting tube  032  that is continuously in directly connect with the scent storage reservoir  006 . Delivery of an electric charge through the nozzle plate  008  sublimates the scent into many scent or drug droplets which laid on the scent collecting chamber  010 . After a sufficient quantity of the scent droplets has been collected, the measured quantity of scent droplets is ionized by unipolar or bipolar electrostatic charge into the scent venting chamber  011 . As above, once the ionized scent vapor has been delivered into the venting chamber  011 , a signal causes the fan or air pump  017  to blow in a series of air flows, each of which can force a ionized scent vapor of either neutralized by a grid or non-neutralized to be expelled through the opening at the end of the venting chamber  011 . The scent vapors are directed at the general vicinity of the user&#39;s face, and more particularly at the user&#39;s nose.  
         [0090]    In one alternative embodiment shown in FIG. 5A,an electrostatic apparatuses having wiring  014  can be integrated into the scents collecting chamber  010  to ionize single or multiple scent liquid into scent molecules. Each individual droplet can be applied through a micro-pumping means, a wicking method, an elastomer funnel, or by some other droplet placing means. Formation of an ionized scent creates very small, precisely measured droplets of the scent which optimizes the surface area relative to the volume. Optimization of the size of the scent improves the vaporization rate and the dispersion rate of the scent into the air.  
         [0091]    In another alternative embodiment shown in FIGS SB and  5 C, a piezo-ceramic vibration plate  013  or a piezoelectric scent pumping apparatus  020  having a pored-orifice  021  or without having a pored-orifice  21 can be integrated into the scents collecting chamber  010  to sublimate single or multiple scent liquid into a vapor. Each individual droplet can be applied through a micro-pumping means, a wicking method, an elastomer funnel, or by some other droplet placing means.  
         [0092]    In a further alternative embodiment shown in FIG. 5D, a thermal plate  016  having wiring  014  can be integrated into the scents collecting chamber  010  to sublimate single or multiple scent liquid into a vapor. Each individual droplet can be applied through a micro-pumping means, a wicking method, an elastomer funnel, or by some other droplet placing means. In yet other embodiment of the present invention, the scent release micro-pumping unit  030  can also include at least one of a piezoelectric scent pumping  020 , as showed in FIG. 6A, a thermal bubble scent pumping  033 , as showed in FIG. 6B, a micro-valve scent pumping  038 , as showed in FIG. 6C, or an electrophoresis scent pumping  039 , as showed in FIG. 6D, to deliver a vapor or droplet scent chemical to the scent collecting chamber  010  through the scent conducting tube  032 . A small amount of the scent chemical can be expelled in a droplet form to the scent collecting chamber  010  through a opening or orifice  035  from a scent release micro-pumping unit. The scent release micro-pumping unit  030  produces droplets that are typically in the range of  10  microns to  20  microns. The droplets are moved into the scent collecting chamber  010  where the droplets are ionized or vaporized and then sprayed into the venting chamber  011 .  
         [0093]    In a preferred embodiment of the present invention, top substrate of the nozzle plate  008  is formed of silicon as it may be micro-machined to obtain a very high precision manufacturing, such a high precision and absence of leachable components being much more difficult to obtain with plastics or the like, for instance by using UV exposure or a plasma etching treatment of various plastic material. The bottom substrate of the nozzle plate  008  is etched so as to form a thinner middle section which may act as a membrane for transmitting a vibration or heat. Bottom substrate may be made of glass, ceramics, silicon, high-density polymer or the like. Top substrate of the nozzle plate  008  preferably consists of silicon, but it may consist of plastic, high density polymer, ceramics, metal or silicon or the like for its main body. As mentioned, outlet pore  035  is formed in top substrate, so that the excited scent  007  may leave the scent release micro-pumping unit  030  as a droplet spray. To this effect, this top substrate is micro-machined, for example in a well known anisotropic etching manner at several places, by using an appropriate mask. By using the usual micro-machining techniques, anisotropic etching is used, thus resulting in straight or cylindrical or of another suitable geometrical shape.  
         [0094]    It is another advantage of using the scent collecting chamber  010  for mixing multiple scents in either gaseous phase or liquid phase. Multiple scents can be delivered into the scent collecting chamber at various quantity through each micro-pumping means to achieve the liquid phase mixing before the vaporization been start by a electrostatic, a ultrasonic nebulizing or a thermal scent release apparatus. To having gaseous phase scent mixing, multiple scents can be delivered into the activated scent release unit at various quantities through each micro-pumping means.  
         [0095]    In order to let ionized scent or therapeutic agent to stick onto the internal surface of nose, it is known that the site of deposition within the respiratory tract of an inhalable substance can be influenced by the level of electrostatic charge on the particles of the inhalable substance. In addition, after electrically charged, they will rapidly deposit on the lining of the nasal cavity or within the upper respiratory tract thereby ensuring that penetration of the particles is limited.  
         [0096]    This is particularly important in the case of for example therapeutic agents to be administered to the upper respiratory tract (e.g. the nasal cavity) because such therapeutic agents may be unsuitable or induce an adverse reaction if inhaled into the lungs. With other materials however it is desirable to deliver the material in a controlled manner to ensure application to the specific area to be treated and/or to improve the efficiency at which the active ingredients are delivered by minimizing the amount of spray outside the target.  
         [0097]    It is yet another advantage of using electrostatic to release scent. The ion can clean off the scent retention over the pore of nozzle plate, so that there will not be any retention or residual of scents after each scent releasing.  
         [0098]    Another object of the present invention is to reduce manufacturing problems and/or costs by providing a disposable scent-bearing and multimedia disk or cartridge in which the nozzle plate, scent conducting tube and scent storage region can be manufactured as one integral part or separate parts.  
         [0099]    In an alternative scent-bearing cartridge  005  embodiment shown in FIGS. 4B, 6E,  6 F,  6 G, and  6 H, the scent storage reservoir  006  can be detached from the micro-pumping unit  030  and replaced with other compatible scent storage reservoir  006  by a user.  
         [0100]    A complete scent release unit  004  having at least one scent release micro-pumping unit  030  made in accordance with the first preferred embodiment of the present invention is shown in FIG. 7. The scent conducting tube  032  can also be formed at the front of the scent release micro-pumping unit to thereby focus the charge from the electrostatic electrode  024  through this scent conducting tube  032  and to the product prior to its dispersal to nozzle tip  035 . Scent is drawn from the scent storage region  006  across the micro-pumping unit  030  towards the outer peripheral surface  035  of the tube. Because of the intensified electric field  024  prevailing in the vicinity of the leading extremity, the liquid is preferentially drawn into one or more ligaments from an edge portion in the locality of extremity and thereafter breaks up within the scent storage and micro-pump release unit  053  into droplets to form the spray. In addition, the asymmetry wiring arrangement can provide multiple scent release units  004  in assembly for a hand-held device integrated scent-bearing cartridge  001 , scent bearing and multimedia disk  012 , micro-pump and electrostatic scent release nosepiece  050 , or many other applications. In an alternative embodiment shown in FIG. 8, a piezoelectric vibration plate  013  can be integrated into the bottom of a scent release unit  004  to sublimate scent liquid  007  in anti-erosive plastic cup or container  042  (e.g. PET, PP etc.) into scent vapor through the transmitting material (e.g. water)  041 . The ultrasonic vibration can be transmitted into the anti-erosive plastic cup  042  through water or other non-erosive liquid  041  by a certain distance (e.g. 110 cm) varied by different vibration frequency or angle.  
         [0101]    In another preferred embodiment of present invention is depicted in FIG. 9, the electromagnetic wave  074  can be delivered to the receiver  075  of the device and induce electrical currents within the generator  076  which then transform into high voltage by a high voltage generating circuit  077 . For advance design, the power supply unit and some control unit can be separated from the scent release unit thus for further wireless operation and device miniaturization.  
         [0102]    In addition, we can also use sufficient electromagnetic waves  074  to ionize scents within the scent collecting chamber  010 . The ionization process happens like this. The electromagnetic wave entering the scent collecting chamber has energy. As it traverses the scent materials, it interacts with electrons of atoms inside those scent materials. Giving some of its kinetic energy to the electrons, the electromagnetic wave ionizes the scent material, knocking off some electrons from atoms.  
         [0103]    In another preferred embodiment of present invention is depicted in FIGS. 10, 11,  13  and  14 , during the scent releasing range control step, a controlled amount of scent neutralizing agent, for example, ozone is released in an air flow faster than the previously-released scent flow to assist in the process of catching up the previously-released scent within a controlled range, thereby neutralizing or degrading the previously-released scent molecules in the air flow; and preventing the scent molecules from trespassing over the controlled range. The step would follow the release scent neutralizing or degrading agent in various angles, as showed in FIG. 12, by automatically rotation of the scent release unit to assist in neutralizing or degrading of the previously-released scent, dust, or other particles within the controlled range.  
         [0104]    In another preferred embodiment of present invention is depicted in FIGS. 10, 12 and  14 , it will be appreciated however, that the automatically rotation scent releasing may actives in response to a sound, a vibration, an infrared imager a camera, or other means of determining the position of the user and the user&#39;s nose.  
         [0105]    A scent release unit  004  made in accordance with sixth, seventh, and tenth preferred embodiments of the present invention is generally shown in FIGS.  20 A-C. The scent release unit  004  comprises an electrically insulated scent storage region  006  containing liquid scent material  007 . Contained within the insulated scent storage region  006  is the ultrasonic nebulizing scent release apparatus  040  for nebulizing scent trapped in the scent collecting chamber  010 . The piezoelectric vibration plate  013  is electrically connected to a power source by wiring  014 . In a variant depicted in FIG. 20B, scent released from scent storage region  006  is released from the scent bearing and multimedia disk by ultrasonic nebulizing scent release apparatus  040 . Under the normal air pressure, the multiple-pored-orifice  021  (size less than 80 micron) will be able to retain the scent or drug liquid. When nebulized scent is created within the scent release unit  004 , it creates droplet smaller than the pore size and a pressure differential between the region within the scent release unit  004  and immediately outside the orifice. This pressure differential causes the droplet to pass those pores, thereby releasing the scent to the scent venting chamber  011  where it can be vented to the user. In an alternate embodiment shown in FIG. 20B electrostatic electrode  024  may be used to assist in the ionization of nebulized scent vapor. There is another alternate embodiment shown in FIG. 20C, thermal-wiring-integrated orifice  016  may be used to assist in the vaporization and remove retention of scent on the orifice  016 . In a further alternate embodiment shown in FIG. 20D electrostatic electrode  024  may be used to assist in the ionization of vaporized scent released from the thermal scent release apparatus  044 .  
         [0106]    A complete scent-bearing and multimedia disk  034  having scent release unit  004  and multimedia storage medium  026  made in accordance with the tenth preferred embodiment of the present invention is shown in FIGS. 21A and 21B. The scent-bearing and multimedia  034  shown in FIG. 21A comprises a plurality of separate scent or drug release units  004 , each of which is contained in a three-dimensional sector of the disk. The scent-bearing and multimedia disk  034  has a multimedia region shown in the interior portion of the disk. The scent-bearing portion of the disk contains a reservoir connected to the portion of the sector containing the scent release units  004 . In an alternate embodiment shown in FIG. 21B, the scent-bearing portion of the disk contains at least a reservoir connected to at least a scent release micro-pumping unit  030 . In FIGS. 21A and 21B, the scent and multimedia-bearing disk  034  is designed to vent scent vertically upward as indicated by the arrow. In an alternate construction shown in FIGS. 22A and 22B, the scent release units  004  extends laterally along a radius of the disk, thereby permitting the scent or drug to be discharged horizontally through an opening in the circumference of the scent-bearing and multimedia disk  034 .  
         [0107]    In yet another alternate embodiment suitable for incorporation in a rectangular scent-bearing cartridge, a plurality of scent release units  004  are shown in FIG. 23. The plurality of scent release unit  004  is located in an interior cavity of the scent-bearing and multimedia cartridge  012 . The cavity has openings to accept an air flow generated by a fan. The airflow passes by the open end of the scent release units  004 . Scent droplet released from the reservoir is entrained in the airflow and vented through opening, where it can be experienced by the user.  
         [0108]    In a still further embodiment of the present invention shown in FIG. 24, a plurality of vertically-oriented scent release units  004  are depicted. In the embodiment of FIG. 25, scent droplet released from the scent release units  004  is vented vertically through single release valves  036 .  
         [0109]    A scent and multimedia -bearing cartridge  012  made in accordance with a tenth preferred embodiment of the present invention is depicted in perspective, top and side views in FIG. 26. The scent and multimedia-bearing cartridge  034  is depicted attached to a Type II DVD-RAM cassette  025  encapsulating an optical storage medium. In variants of the present invention, the encapsulated optical storage media can take the form of DVD-RAM and other known and contemplated DVD storage formats, for example DVDR, DVD-RW, DVD+RW, etc.  
         [0110]    Scent is released from the scent-bearing cartridge  005  using a scent release unit  004  as shown in FIG. 27. The scent release unit comprises at least one scent release unit  004  which deliver scent from the scent storage region  006  to the outlet. In variants of the tenth preferred embodiment, the scent release unit  004  can operate on an evaporation principle, electrostatic principle, or nebulizing principle. The data storage medium  043  (e.g., SIM card, flash memory, memory chip) is shown on the side of scent-bearing cartridge  005 .  
         [0111]    An eleventh preferred embodiment of the present invention is depicted in FIGS. 28A and 28B, and comprises a micro-pump and electrostatic scent release nosepiece  050 . The nosepiece  050  is formed of silicon or other material as it may be micro-machined to obtain a very high precision manufacturing and miniaturization. In operation, multiple scents are first stored within the scent storage and micro-pump release unit  053  and controlled by the control unit  051  through the wiring linkage of the flexible plastic piece  052 .  
         [0112]    A multimedia playback and electrostatic scent release desktop diffuser  070  having scent-bearing cartridge  005  made in accordance with the twelfth preferred embodiment of the present invention is shown in FIGS. 29, 30 and  31 .
