BRIEF SUMMARY OF THE INVENTION
The present invention comprises a system and method that has one or more of the following features and/or steps, which alone or in any combination may comprise patentable subject matter.
In accordance with one embodiment of the improved sexual stimulation device of the invention, the invention is a vibrating stimulator for female use which may incorporate one or more therapeutic light sources and may also incorporate one or more mechanical stimulators in the form of vibrators, which, when applied to the clitoris or vagina, or both, cause increased stimulation and/or therapeutic effect resulting in an enhanced sexual experience for the user. In accordance with an alternate body of the invention, the invention is a stimulator for male use which incorporates a light source for increased stimulation and/or therapeutic effect.
In the prior art female sexual stimulation devices were designed to vibrate and stimulate the nerves of sexually sensitive areas of the female anatomy, for instance the clitoris or Gräfenberg Spot (G-spot). Although effective, this method of stimulation typically bypasses or rapidly moves through one of the most important phases of the sexual response cycle which is the arousal phase. This phase, also known as the excitement phase, is characterized by increased blood flow to the clitoris and vagina as well as an increase in muscle tone to the vagina and anus. The present invention may utilize therapeutic light energy to enhance genital blood flow. The ability of specific wavelengths of light to stimulate blood flow through the application of light energy is well established throughout medical literature. The application of light energy to certain parts of the body may improve blood flow and may therefore improve sexual response with or without a partner. Improved blood flow can also extend a woman's sexual lifespan. The apparatus and method of the invention causes greater clitoral swelling and signs of improved genital blood flow, which may result in enhanced or more frequent orgasms (or both). Additionally, the present invention may utilize specific wavelengths of therapeutic light to decrease vaginal and vulvar bacteria and fungi populations. The medical and environmental literature is replete with data demonstrating specific wavelengths of light to be bactericidal, bacteriostatic, fungicidal and fungistatic. The application of such light energy to the vagina, vulva, clitoris, and penis may reduce bacterial and fungal infections that may be caused by the use of stimulating devices or exist unrelated to such.
A preferred embodiment of the invention comprises a handle portion which may house control elements such as buttons, switches and the like, a vaginal finger which may contain at least one vibrator and at least one light source for insertion into the vagina of a female user, and a clitoral finger which may contain at least one vibrator and at least one light source for application to the clitoris of a female user. It is preferred that, when a preferred embodiment of the improved sexual stimulation device of the invention is used in a best mode, the vaginal finger directly applies vibration and light stimulation on or near the Gräfenberg Spot, or G-spot, of a female user, and the clitoral finger directly applies vibration and light stimulation on or near the clitoris of a user. In this manner, vibration and light stimulation are directly applied to the areas of the body known to result in maximum arousal and sexual stimulation. The improved sexual stimulation device of the invention may be used in numerous orientations and modes which are limited only by the imagination of the user or the user's partner, and are therefore not to be limited by the best mode described herein. Although the preferred embodiments combine therapeutic wavelengths of light with vibration, other forms of mechanical stimulation such as that used in neck massagers and massaging chairs may also comprise the invention.

DETAILED DESCRIPTION OF THE INVENTION
The following documentation provides a detailed description of the invention.
The invention is a device primarily intended for sexual stimulation of a female user. The improved sexual stimulation device of the invention may comprise a vaginal finger which may further comprise at least one therapeutic light source and a means for mechanical stimulation, which may comprise a vibrator; a clitoral finger which may further comprise at least one therapeutic light source and a means for mechanical stimulation, which may comprise a vibrator, and a handle which may comprise a keypad, controller, and a battery. The apparatus of the invention may use mechanical stimulation which may also be combined with a therapeutic light source or multiple therapeutic light sources so that, when applied to the body of a user it provides a therapeutic effect on the tissue of the vagina, and or vulva and or clitoris as described below. As used herein, “mechanical stimulation” shall mean any energy that exerts a perceivable movement to the tissue upon which it is applied.
The light source or light sources may be automatically powered when the mechanical energy element of the device is powered to an ON state, or may be configured so as to operate independently from the source or sources of mechanical energy. At least one light source, but preferably a plurality of light sources, provide light energy that exits the device at one or more points, preferably at a point along the length of the vaginal finger and also at a point along the length of the clitoral finger, which may irradiate the tissue in the vagina and may irradiate the body of the user on or near the clitoris or vulva. A preferred embodiment of the improved sexual stimulation device of the invention may comprise both a vaginal vibrator and a clitoral vibrator. The vaginal vibrator and clitoral vibrator may comprise any vibrating element small enough to fit within the envelope of vaginal and clitoral fingers of the invention. In a preferred embodiment, the vaginal vibrator and clitoral vibrator may be defined as a DC motor with offset weights mounted on the motor shaft such that the center of mass of the weight is offset from the axis of rotation of the motor. When such motors are powered to an on state, a vibration results from the offset nature of the center of mass of the weight mounted onto the vibrator motor shaft. While the vibrators of the preferred embodiment may exhibit any rate of vibration, a preferred range of vibration rate is 5,000 to 25,000 rpm. Such offset vibration motors are well known in the art for use as sources of vibration. One such vibration motor is supplied by Shenzhen Kinmore Motor Co. of Guangdong, China, part number FF-N20VA-09170 R6x4.8. However, any small source of vibration or mechanical energy may be used as the vibration elements of the invention. For instance, sonic pulses have been shown to have a vibratory effect, and may be used as a vibration source in either the vaginal finger, the clitoral finger, or both. An alternate embodiment of the invention may thus use at least one sonic pulse generator as a source of vibration; or, alternatively, may comprise vibration means that produce other forms of mechanical stimulation such as, for example, rubbing, tapping, pressure, and pressure that varies with time.
The invention may emit therapeutic light energy that irradiates the areas on or near the Gräfenberg Spot inside the vagina, and may also irradiate the area on or near the clitoris and or elsewhere on the vulva or perineum. The Gräfenberg Spot, often called the G-Spot, is defined as a bean-shaped area of the vagina. Some women report that it is an erogenous zone which, when stimulated, can lead to strong sexual arousal, powerful orgasms and female ejaculation. The G-Spot is typically described as being located one to three inches (2.5 to 7.6 cm) along the front (anterior) vaginal wall between the vaginal opening and the urethra and is a sensitive area. It is one objective of the invention to irradiate the G-spot and the area in proximity to the G-spot with light energy. However, the emitted light energy may also be directed through a broader or de-focused beam to surrounding tissues of the vagina. The concentration or de-focusing of light energy on specific areas such as the Gräfenberg Spot or clitoris may be achieved by varying the placement of the light energy exit points of the invention, which may be a single or a plurality of exit points, and which may be covered by a wavelength transparent material, at appropriate positions on the apparatus in order for the exiting light energy to impact the intended area or areas. Similar alterations in light projection may be created by placing a lens or lenses over the light source or sources.
The light energy delivered by the device may be within a plurality of different ranges of wavelength. The light sources of the invention may be any light source such as Light Emitting Diode (LED), laser diode, organic LED (OLED) or any other light source which is compact enough to be enclosed in the apparatus. The wavelength of the light source, or sources, of the invention may be any wavelength, but is preferably in the range from 400 nm to 1000 nm. A plurality of light sources, which may be of different wavelengths, may be utilized; it is not necessary that a single source be used or that each of a plurality of sources emit light of the same wavelength. A preferred embodiment utilizes a plurality of light sources that, taken together, enables the invention to emit more than one wavelength range of light energy. The light energy used may be such to limit therapeutic penetration to less than 5 mm from the tissue surface and to have greater than 50% drop off of energy beyond such depth because the intended nerves and vessels that are the subject of stimulation are essentially superficial. Light energy may be delivered in continuous or pulsed form, where the pulses may take any shape and be of any duration. The power level of the light energy emitted by the light sources of the invention may be modulated in any fashion such as, for example, pulse width modulation, but preferably is controlled by increasing or decreasing the electrical current through the light source. “Light source” as used herein means a device that converts electrical energy to light energy such as an LED, OLED semiconductor laser, or any other device that exhibits this characteristic.
More specifically, a preferred embodiment of the improved sexual stimulation device of the invention comprises more specific ranges of bandwidth and output power of the light sources which are now described. The selection of bandwidth and output power of the therapeutic light sources for this preferred embodiment is based upon the demonstrated effects of photostimulation or photobiomodulation. It has been demonstrated that light sources emitting energy in the infrared and near infrared spectrum may provide photostimulation and photobiomodulation for the temporary relief of minor muscle and joint pain, muscle spasm, pain and stiffness, by promoting relaxation of the muscle tissue and temporarily increasing local blood circulation. As used herein, the term “light therapy” refers to the use of one or more light sources of any type that emits light with a wavelength between about 400 and 1000 nm.
Light therapy induces a variety of photo-thermal and photo-chemical processes in the body. Infrared light, near infrared light, and red light affect cellular mitochondria and activate surrounding enzymes resulting in the release of Nitric Oxide, ATP, and trigger photo neurological responses which result in changes in local pressure, temperature and permeability of cellular membranes, and stimulation of the immune, lymphatic and vascular systems. Organic nitrates are used every day in emergency rooms around the world to improve blood flow to the heart. There is also an inverse relationship between nitric oxide pathways and atherosclerosis. Patients with impaired NO pathways seem to have higher amounts of blood vessel plaques (narrowed blood vessels with poor blood flow and oxygen delivery to tissues). Over time, improved NO pathways may decrease atherosclerosis and create healthier “younger” blood vessels. Within the 400 to 1000 nm range is therapeutic blue light. Blue light energy has a bactericidal and bacteriostatic effect and has been shown to kill and disrupt growth of pathogenic bacteria. This inactivation mechanism, known to be oxygen dependent, is thought to be a result of the photoexcitation of naturally occurring endogenous porphyrins, which act as endogenous photosensitizers within the bacterial cells. This porphyrin excitation leads to energy transfer and, ultimately, the production of highly cytotoxic, oxygen-derived species, most notably, singlet oxygen. Although ultraviolet light is also lethal to many pathogenic bacteria, as we know, UV light is very detrimental to the skin. Blue light is much safer. Over time, blue light can safely lead to a reduction in pathogenic bacteria on skin and mucous membrane surfaces. Near IR light, also within this preferred spectrum of therapeutic light, damages the genetic material inside of fungus (DNA). DNA damage leads to impaired fungal growth. Over time the yeast population on skin and mucous membranes decreases. The use of IR light to treat toe nail fungus is now common medical practice.
Wavelength and power density are the two most prominent factors that determine the effectiveness of a light therapy source. The wavelength of the light source determines the absorption rate and penetration depth of the light energy in biological tissue. The power density of the light source, in combination with its wavelength, determines the effect the emitted light produces on body tissue, bacteria, and fungi. The effects of light therapy with therapeutic light have been studied for applications in, for example, pain relief and tissue healing: in, fact, about 2,700 clinical reports have been published in peer reviewed technical journals or conference proceedings with more than 70% of the reports indicating that light therapy is effective for tissue healing and pain relief. Clinical reports demonstrate that light therapy is effective, for instance, for the relief of muscle and joint pain, muscle spasm, pain and stiffness associated with arthritis, by promoting relaxation of the muscle tissue and temporarily increasing local blood circulation, without side effects. An even greater amount of data exist for the effects of light on bacteria and fungi.
It has also been shown that various pulse formats have a positive effect on photostimulation. Off-times between light pulses of 50 ms to 500 ms may have the greatest effect on cell organelles and plasma membranes. It is postulated that when this range of pulse formats is used, the re-oxidation of cytochrome c oxidase is optimized. This optimization leads to increase energy in the cell leading to improved blood flow and tissue repair. Pulsing of the light source is used to optimize the photobiological response though a temporal optimization as well as dosage control. Optimal dosages of light range from of 0.001 J/cm2 up to 3000 J/cm2. These dosages can be controlled through changing the intensity of the light source, changing the irradiation time, and by light source pulse shape and timing. Therapeutic results can be seen using intensities ranging from 0.001 W/cm2 to 100 W/cm2.
Studies have concluded that photostimulation can increase blood flow. Increased blood flow is critical for bodily functions and is an important factor in the excitement phase of sexual stimulation. Photostimulation enhances vasodilatation and proliferation of the microvasculature as well as increases the level of oxygen content to tissue of the irradiated area, in this case, the G-spot area, and the area surrounding the clitoris. In a recent study which compared a photostimulated group of human test subjects to a non-photostimulated group of human test subjects, the photostimulated group increased blood flow to the exposed area for over 12 hours. This study showed the capillaries of the human subjects were enlarged and thus blood flow increased as a result of photostimulation. Photostimulation activates the powerhouse for the cell to increase the rate at which it produces energy. This activation increases the production of critical biochemical substances such Nitric Oxide (NO) and Vascular Endothelial Growth Factors (VEGF). These growth factors also promote new blood vessel growth. These biological responses to light therapy explain why photostimulation can have both an immediate and cumulative effect on a subject's level of sensation during sexual stimulation. As noted above, it has also been shown in laboratory studies that light energy in certain bandwidths may also have an anti-bacterial effect. Clinical studies have verified this antibacterial effect on patients for light sources between 405 nm and 420 nm. It has also been shown that a combination of blue and red output from LEDs can be a very effective treatment of both inflammation and antibacterial results. Recent studies have shown that blue LEDs irradiating the skin may result in a seven to fifteen times increase in the NO level in tissue as deep as 18 mm below the skin's surface.
Based on the effects of light therapy on human tissue, it is a feature of a preferred embodiment of the invention that blue light sources emitting light energy in the ranges of 400 nm to 515 nm or 530 nm to 670 nm at a output of at least 300 millicandelas peak with a half-power output angle of +/−60 degrees, red light energy in the ranges of 610 nm to 640 nm at a output of 300 millicandelas peak with a half-power output angle of +/−60 degrees, and infrared light energy in the range of 820 nm to 880 nm at an output radiant flux of at least 300 mW peak with a half-power output angle of +/−60 degrees with each light source irradiating in pulses of equal on and off times between 50 msec and 500 msec, is one embodiment of many that creates the desired effects on tissues associated with the use of adult pleasure objects. Said effects are including, but not limited to, improved blood flow, improved blood vessel health, tissue regeneration, tissue tightening, improved cellular respiration, improved lubrication, decreased bacteria, decreased fungi, enhanced arousal and even pain relief. These effects may be directly caused in a user by use of the improved sexual stimulation device of the invention, as described herein. It is to be noted that this is just one of many embodiments of the invention, and any number of light sources emitting light energy within the range of 400 nm to 1000 nm at any radiant flux or millicandela output and angle may be used in any light source group of the invention. In order to emit the various bandwidths of light energy, each light source group may comprise more than one type of light source. For example, in the preferred embodiment described for which multiple frequencies of light are emitted by a light source group, a light source group may comprise light emitters which are defined as a plurality of LEDs, a plurality of lasers, or a plurality of light sources comprising a combination of LEDs and lasers. The light sources of the invention may be adapted to provide continuous output or provide output energy in pulses of any wave shape. “Half power angle” as used herein means the off-axis angle where the light source's luminous intensity is half the intensity at direct on-axis view. The axis of the light source is defined as the line of the vector of maximum intensity emanating from the light source.
In the various embodiments, the light energy may be pulsed on and off and may be any output energy with the ranges of output energies set forth herein. These light source output wavelengths may be administered in pulses that are in phase or out of phase as between light sources, and may be of any timing desired. It is an aspect of the invention that such light source pulse shape and timing may be, for some embodiments, programmable by use of a controller in communication with the light sources. The controller may be programmed by the user to produce a desired pulse shape and timing for the light sources of the invention. Alternatively the controller may be preprogrammed by a non-user.
In another preferred embodiment, these wavelengths, pulse widths, rest periods, and output power may be combined with mechanical energy such as that provided by an unbalanced vibration motor typical to that found in an adult sex toy, or any other method of mechanical energy delivery known in the art. In this manner, light therapy and mechanical stimulation, and, more specifically, vibration, may be applied together, or in alternating patterns of the user's choice, in order to achieve a desired stimulation effect.
In a preferred embodiment of the device, the light sources may be delivered to the tissue through an optical diffusing element, such as, for example, a silicone cover, to assure a homogeneous exposure of light to the selected tissue. In an alternate embodiment the device, the light sources may produce a selected pattern of optical energy to deliver optical energy to specific spots to provide differential exposure to unique spots on the tissue.
Yet further alternate embodiments will have preprogrammed light energy pulse patterns and or vibration patterns. The preferred embodiment comprises separate buttons for activating and choosing vibrations patterns and or light energy patterns.
In some of the specific preferred embodiments described herein, the mechanical stimulation example given is described as mechanical vibration produced by, for example and not by way of limitation, an offset vibrator motor. However, it is to be understood that the scope of the alternate embodiments of the invention includes all types of mechanical simulation devices and methods known in the art and which are adaptable to the invention without undue experimentation, such as sonic vibrators and mechanical manipulators of any type that produce rubbing, tapping, pressure, pressure that varies in intensity over time, and all other methods for mechanical stimulation.
Referring now to FIG. 1, a preferred embodiment of the sexual stimulation invention is shown in perspective view. The invention comprises vaginal finger 200, clitoral finger 300, handle 400 and keypad 403. The device is intended to be used primarily by a female user, who, in the most general case, would hold the invention with one hand or both hands by handle 400 and slidingly engage vaginal finger 200 in a vagina such that vaginal finger 200 applies vibration and vaginal light energy 201 within the vagina at or near the G-spot, while clitoral finger 300 may apply clitoral light energy 301 and vibration at or near a clitoris. The application of light energy and vibration at or near the G spot and clitoris in continuous fashion, or in patterns of vibration and light therapy as may be programmed into the invention, operate to cause more rapid and intense stimulation than is possible without the invention. One exemplary method of the invention may comprise the following steps: applying lubrication, a lubricating light coupling agent or a combination of such agents as desired to vaginal finger 200 or clitoral finger 300, or both, slidingly engaging vaginal finger 200 in a vagina while resting clitoral finger 300 on or near a clitoris, turning the vaginal light source group 202 and clitoral light source group 302 of the apparatus ON, turning the vaginal vibrator 204 and clitoral vibrator 304 of the apparatus ON, and holding and applying movement as desired by grasping handle 400. Alternatively, light source groups and or vibrators may be turned on prior to contact of fingers to body tissue. The invention may further comprise control circuitry located in the handle 400 of the invention which may be used to operate the invention in one or more of many possible operational modes which are discussed further herein. Keypad 403 may cover the internal circuitry of the invention in such a manner as to provide environmental protection for the circuitry while at the same time allowing a user to control the operation of the invention by pressing on keypad 403 which is in physical contact with and engages switches 500 in electrical communication with the control circuitry. In normal use, handle 400 remains outside the body of the user. It can further be seen from FIG. 1 that vaginal finger 200, clitoral finger 300 and handle 400 form a unitary structure. In an alternate embodiment, clitoral finger 300 may not be present: in this alternate embodiment vaginal finger 200 and handle 400 form a unitary structure.
Referring to FIG. 2, vaginal finger 200 and the clitoral finger 300 are shown as vibrating, as during normal use in the preferred embodiment shown. Vaginal light energy 201 may irradiate body tissue at or near the G-pot as it radiates from a side of distal end of vaginal finger 200 through flexible cover 402. Clitoral light energy 301 may irradiate body tissue at or near the clitoris as it radiates from the distal end of clitoral finger 300 through flexible cover 402. Flexible cover 402 may cover vaginal finger 200 and clitoral finger 300 and may, in a preferred embodiment, provide a hypo allergenic cleanable covering for vaginal finger 200 and clitoral finger 300. Flexible cover 402 may be fabricated from any material suitable for this purpose and transmissive at frequencies of 400 nm to 1000 nm including, but not limited to, silicone. The use of silicone in this preferred embodiment exhibits reduced friction characteristics which facilitates sliding engagement of vaginal finger 200 into the vagina of a user and also facilitates reduced frictional properties when clitoral finger 300 is in contact with the body of a user on or near the clitoris. Keypad 403 covers switches 500 (not shown in FIG. 2) which, in this preferred embodiment, are located within handle 400. The anterior side of keypad 403 is directly pressed by a user, for example by a user's finger, in order to activate controls of the invention. The posterior side of keypad 403 comprises keyboard button nipples which engage switches 500 (not shown in FIG. 2) disposed on a surface of controller printed wiring board 418 (not shown in FIG. 2) when a user presses any of the depressible control buttons disposed on the anterior side of keypad 403. In this way, a user may control the improved sexual stimulation device 100 to power the device on or off, and to command to operate in any of the modes described herein.
Referring now to FIG. 3, a front view of a preferred embodiment of the improved sexual stimulation device 100 of the invention is shown. Keypad 403 comprises a first depressible control button 405, a second depressible control button 406, a third depressible control button 407, fourth depressible control button 408, and fifth depressible control button 409 which are operated by a user to control the device. As described further herein, pressing downward on a depressible control button of the invention causes a keypad button nipple 428 (not shown in FIG. 3 but described further herein) disposed on the underside of keypad 403 to engage switches 500 (not shown in FIG. 3), which are in electrical communication with controller 501, providing commands as desired by the user to controller 501 (not shown in FIG. 3). The functions of the five depressible control buttons depicted in FIG. 3 are discussed hereinbelow. It is to be noted that the operational modes described herein are exemplary. Due to the programmable nature of controller 501 the depressible control buttons of the invention may be programmed to provide any combination of vibrator or light source on state, vibrator or light source off state, intensity of light, intensity of vibration, selection of pre-programmed vibration pulse shapes or continuous operation, selection of pre-programmed light energy pulse shapes or continuous operation, test modes, light energy and vibration display modes, and the like, may be programmed into the invention, selected and operated by a user pressing the depressible control buttons of the invention, which may be programmed to command any of these operations. Mechanical stimulating components other than vibrating motors may be substituted for vibrating motors and similarly controlled.
Referring now to FIG. 4, a rear view of a preferred embodiment of the improved sexual stimulation device 100 of the invention is depicted. Shown in FIG. 4 are first cavity 420, second cavity 421 and third cavity 425, which may provide recessed insertion points for handle rear cover fastener 415 which are inserted through first cavity 420, second cavity 421 and third cavity 425 and are threadingly engaged into receiving female threads located on main support structure 412 (not shown in FIG. 4), and are therefore used to hold handle rear cover 413 into place. Alternatively, such cavities may be replaced by molded pins communicating with glue bosses rather than screw bosses.
Referring now to FIG. 5, an exploded view of the preferred embodiment of the improved sexual stimulation device 100 of the invention is depicted. It is to be noted that, while a specific structure is shown in FIG. 5, there are many equivalent structures which are covered by the claims, and that the scope of the invention includes equivalent structures as would be understood by a person of ordinary skill in the mechanical arts.
Still referring to FIG. 5, main support structure 412 is an elongate mechanical structure, preferably molded from plastic, but also, if desired, cast from metal or machined from any stable substantially rigid material such as plastic, phenolic, or other materials known in the art. Main support structure 412 provides support and attachment points for the various components and internal elements of the invention. The attachment points may generally be female bosses which are adapted to receive male threaded fasteners, and which may be threaded with female threads or may receive self-threading male threaded fasteners. All such female bosses may also serve as adhesive bosses to receive male pins and adhesive. Bosses, screw and pins may be decreased in number or removed in entirety if ultrasonic or similar welding is used to secure surfaces.
Still referring to FIG. 5, the attachments of keypad 403 and handle front cover plate 410 are discussed. Keypad 403 rests upon main support structure 412 and may be preferably bonded into place thereon using any suitable adhesive for bonding keypad 403, which may be fabricated from, for example, silicone, silicone compounds or any flexible polymer material. Alternatively, keypad 403 may be allowed to simply rest in place, sandwiched between handle front cover plate and main support structure 412. Keypad 403 may comprise a plurality of keypad button nipples 428 (not shown in FIG. 5) that act to engage switches 500 when a depressible control button is depressed.

While these exemplary light source groups are discussed herein as regards the modes of operation of the invention, it is to be understood that the exact number of light sources in each light source group is variable, as well as are the frequencies of light emitted, the output power of the emitted light energy, and the modes of operation. Thus, a light source group may consist of two “blue” LEDs, three infrared LEDs, only one “red” LED, and LEDs with differing wavelengths and output powers other than the blue, red and infrared light sources described above, and so on. All combinations of light source types are considered within the scope of the claimed invention. Furthermore, alternate embodiments of the invention may comprise a light source or light sources disposed only in clitoral finger 300 and not in vaginal finger 200, and vice versa. Additionally, alternate embodiments may utilize light sources known in the art that are disposed in the handle of the device or external to the device whereby therapeutic light energy is transmitted to vaginal and or clitoral finger through light tubes or fibers.
Referring now to FIG. 8, an electrical block diagram of the sexual stimulation device 100 of the invention is depicted.

Controller 501 may reside on controller printed wiring board 418 (not shown in FIG. 8) and be soldered thereto. Controller 501 may be a single electrical device or a plurality of electrical devices that allow control inputs to be accepted from a user through the use of keyboard 403, by a user depressing one or more depressible control buttons as hereinbefore described. Controller 501 may comprise any electrical components known in the art for accepting commands and providing an output based on user inputs, pre-programmed data, or combinations thereof. Thus, controller 501 may comprise programmable logic devices, non-field-programmable firmware devices, field programmable firmware devices, microprocessors, microcontrollers, discrete logic and other logic devices adapted to perform the functions of receiving an input from a user and commanding the vibrators or other motors and light sources of the invention to operate in any desired modes, which are further defined herein. Memory 502 may be integral with the controller 501, such as “on-board memory” or may be one or more separate memory devices in electrical communication with controller 501. Memory 502 may be utilized to store pre-programmed modes of operation and to store other information as may be required by controller 501. Battery 503 is in electrical communication with and provides power to drive controller 501, memory 502, clitoral light source group 302, clitoral vibrator 304, vaginal vibrator 204, vaginal light source group 202, and any other electrical devices of the invention. Battery 503 may drive these devices directly or may drive them through their electrical connection with controller 501. Battery 503 may also be in electrical communication with charge circuit 506, which may condition power received through charging port connector 451. Alternatively, charging port connector 451 may be in direct communication with battery 503 for directly charging the battery. Battery 503 may also be in electrical communication with inductive charging circuit 505, which may be adapted to produce a charging current when placed in proximity with magnetic field, as is known in the art of inductive charging circuits. In a further alternate embodiment, not shown in FIG. 8, battery 503 may comprise a replaceable battery or group of batteries, such that they are replaced with a new battery or group of batteries when a given discharge level is reached, for example, when battery 503 is no longer able to power the improved sexual stimulation device 100 of the invention to a user's satisfaction. In any of the embodiments described herein, battery 503 may be a single battery or a group of batteries. Also, the electrical connection at charging port connector 451 may be any connector suitable to fit within the envelope of the invention and provide electrical communication as described herein. Thus, any type of electrical connector, whether a standard connector or a custom connector, may be used and is therefore within the scope of the claims. In a still further embodiment, charging port connector 451 may be in electrical communication with controller 501 such that modes of operation, firmware for operation of the vibrators and light sources of the invention, programming of keypad button functions, and other programmable aspects of the invention may be download and or uploaded and used by controller 501 and stored in memory 502. Thus, charging port connector 451 may also be a programming port.
Still referring to FIG. 8, controller 501 may further comprise an infrared or RF wireless interface such as, for example, the interface known as Bluetooth®, the interface known as WiFi, the interface known as Near Field Communications (NFC) or any other wireless interface as is known by persons of ordinary skill in the art, in order to wirelessly control the invention and download new or changed modes of operation information and or other information and the like to be stored in either controller 501 or memory 502, or the like. Any type of information may be downloaded and stored in this manner. Such wireless interfaces are well known in the electronic arts and, as such, do not require undue experimentation to understand and implement.
Still referring to FIG. 8, controller 501 may be in electrical communication with a vaginal light source group 202 through vaginal finger wires 448 (not shown in FIG. 8), a clitoral light source group 302 through clitoral finger wires 443 (not shown in FIG. 8), a vaginal vibrator 204 through vaginal finger wires 448 (not shown in FIG. 8), and a clitoral vibrator 304 through clitoral finger wires 443. These devices may be powered off, powered on, pulsed, operated continuously, or driven to various levels of output power directly by the circuitry of controller 501, or by drivers 452, 453, 454, or 455 which may be in electrical communication with controller 501, as the user desires. These drivers may be discrete electric circuits or may be incorporated directly in controller 501 as “on-board” drivers. Vaginal light source group 202, clitoral light source group 302, vaginal vibrator 204, and clitoral vibrator 304 may thus be individually commanded by controller 501 to operate in any patterns desired by the user, which patterns may be coordinated in order to achieve a desired stimulation effect in the user. The patterns of control are discussed below.
Still referring to the preferred embodiment of the invention depicted in FIG. 8, controller 501, memory 502, charge circuit 506, and drivers 452, 453, 454, and 455 are located on controller printed wiring board 418 (not shown in FIG. 8), which may be located in handle 400 (not shown in FIG. 8) along with keypad 403.

Vaginal vibrator 204 and vaginal light source group 202 may be located in vaginal finger 200 (not shown in FIG. 8) and clitoral vibrator 304 and clitoral light source group 302 may be located in clitoral finger 300 (not shown in FIG. 8). In alternate embodiments of the invention, the various components comprising the invention may be located in any location within the invention and interconnected electrically as is conceivable by the techniques and methods known by persons of ordinary skill in the electro-mechanical arts. Such alternate embodiments are within the scope of the claims, as are equivalent structures and components.
Exemplary modes of operation and control of the states and patterns used to operate the vibrators and light sources of the invention are now discussed. While a preferred embodiment is discussed for purpose of description herein, it is to be understood that the programmable nature of the invention allows any variation, and therefore any pattern, of intensity and wave shape for both the light sources and vibration of the invention. Thus, the embodiment shown is exemplary only. The intensity of vibration of clitoral vibrator 304 and vaginal vibrator 204 may be controlled by pulse width modulation (PWM) control of power to the vibrator motor by controller 501, such that, for example, a 50% duty cycle represents LOW power, a 75% duty cycle represents MEDIUM power, and a 100% duty cycle represents HIGH power. These designations of power level may be set as desired, such that various terms may be given to corresponding duty cycles, and any number of power levels, which are the result of variation of the pulse width of the PWM drive signal driving the vibrators, may be defined as desired. It is a feature of controller 501 that any of the vibrators of the invention may be driven at any duty cycle desired, whether constant or in a pattern such as a pulsed pattern, sinusoidal pattern, or otherwise, based upon the desire of the user as programmed into controller 501, and, preferably, stored into memory 502.
A user may depress the depressible buttons 405-409 on keypad 403 to control operation of the invention in the following manner. It is to be understood that, due to the programmable nature of the invention, any combination of vibration patterns and light patterns may be programmed into controller 501 and memory 502. The modes of operation described hereinbelow are exemplary and not limiting. In the exemplary embodiment used in for description of operating modes below, vaginal light source group 202 comprises “blue” LEDs, “red” LEDs and an infrared LED; and likewise clitoral light source group 302 comprises “blue” LEDs, “red” LEDs and an infrared LED. Again, these configurations of light source groups are merely exemplary. Furthermore, in the exemplary embodiment used in for description of operating modes below, vaginal finger 200 comprises a vaginal vibrator 204 and clitoral finger 300 comprises clitoral vibrator 304.
In the exemplary embodiment, the invention may be powered on by pressing first depressible control button 405 and third depressible control button 407 simultaneously for three seconds, which may power the invention ON in a base operating mode. In this mode, vaginal vibrator 204 operates in a continuous LOW power state; the blue, red and infrared LEDs of vaginal light source group 202 are powered in the base pattern depicted in FIG. 9; clitoral vibrator 304 operates in a LOW power state; and the blue, red and infrared LEDs of clitoral light source group 302 are also powered in the base pattern depicted in FIG. 9. Next, pressing and releasing second depressible control button 406 may cause controller 501 to command clitoral vibrator 304 and the light sources of clitoral light source group 302 to an OFF state. Next, pressing and releasing second depressible button 406 may cause controller 501 to command clitoral vibrator 304 to a continuous LOW power state, and cause the light sources of clitoral light source group 302 to operate in the base pattern state of FIG. 9, while commanding vaginal vibrator 204 and the light sources of vaginal light source group 202 to an OFF state. Next, pressing and releasing second depressible button 406 may cause controller 501 to command vaginal vibrator 204 and clitoral vibrator 304 to pulse between OFF and ON states in an out-of-phase pattern in LOW power mode, while commanding the light sources of both vaginal light source group 202 and clitoral light source group 302 to operate in the base pattern shown in FIG. 9. Next, pressing and releasing second depressible button 406 may cause controller 501 to command vaginal vibrator 204 and clitoral vibrator 304 to pulse between OFF and ON states in an in-phase pattern with a high pulse rate, such as, for example, greater than 2.0 Hz pulse rate, in LOW power mode, while light source groups 202 and 302 remain operating in the base pattern shown in FIG. 9. It is to be understood that the pulse rate may be any rate commanded by controller 501. Next, pressing and releasing second depressible button 406 may cause controller 501 to command vaginal vibrator 204 and clitoral vibrator 304 to operate in a substantially sinusoidal-shaped intensity profile, in which the PWM signal driving each vibrator is characterized by a pulse width that varies sinusoidally. Next, pressing and releasing second depressible button 406 may cause controller 501 to command vaginal vibrator 204 and clitoral vibrator 304, and light source groups 202 and 302, back into the base operating mode described above in which vaginal vibrator 204 operates in a continuous LOW power state; the blue, red and infrared LEDs of vaginal light source group 202 are powered in the base pattern depicted in FIG. 9; clitoral vibrator 304 operates in a continuous LOW power state; and the blue, red and infrared LEDs of clitoral light source group 302 are also powered in the base pattern depicted in FIG. 9.
Continuing to discuss now the exemplary mode of operation described above, when the invention is in the base operating mode, pressing third depressible control button 407 alone causes controller 501 to command vaginal vibrator 204 and clitoral vibrator 304 to increase intensity by commanding a higher duty cycle as hereinbefore described, and pressing third depressible control button 407 again causes controller 501 to command vaginal vibrator 204 and clitoral vibrator 304 to further increase intensity. Each press shall result in an increase of 1⁄6th of intensity range until maximum intensity is reached. Thus, in the exemplary base operating mode described herein, pressing third depressible control button 407 generally results in an increase in perceived vibration intensity to the user. Likewise, when the invention is in the base operating mode, pressing first depressible control button 405 alone causes controller 501 to command vaginal vibrator 204 and clitoral vibrator 304 to decrease intensity by commanding a lower duty cycle. Thus, in the exemplary base operating mode described herein, pressing first depressible control button 405 generally results in a decrease in perceived vibration intensity to the user. In this manner the user may select a desired intensity of vibration. Any number of vibration intensity levels may be programmed into controller 501 and memory 502.
Continuing to discuss now the exemplary mode of operation described above, when the invention is in the base operating mode, depressing and holding fifth depressible control button 409 may cause controller 501 to command vaginal vibrator 204 and clitoral vibrator 304 and the light sources of light source groups 202 and 302 to cycle through a series of programmed states which may include, for the vibrators: continuous ON in LOW power state, continuous OFF state, pulsed ON and OFF in both in-phase and out-of-phase states; and sinusoidal in both in-phase and out-of-phase states; and, for the light source groups 202 and 302: continuous ON state for all light sources, continuous OFF state for all light sources, the base pattern and other patterns shown in FIG. 9. The invention may cycle through each of these states in series as programmed into controller 501 and memory 502, taking, for example, approximately seven minutes to complete the cycle. The length of time of the cycle may be programmable, as is the sequencing and description of the states of the vibrators and light sources. Pressing any button during the cycle may return the invention to the base operating mode. A exemplary preferred program of light energy and motor stimulation is shown in FIGS. 9 and 10.
Continuing to discuss now the exemplary mode of operation described above, when the invention is in the base operating mode, pressing first depressible control button 405 and third depressible control button 407 simultaneously for three seconds may cause controller 501 to command vaginal vibrator 204 and clitoral vibrator 304 to an OFF state, and likewise commend all light sources of vaginal light source group 202 and clitoral light source group 302 to an OFF state.
It is to be noted that pulse width of the PWM drive signal to the vibrators of the invention may be varied independently of one another by controller 501 in any pattern desired such as, for example, continuous ON, continuous OFF, sinusoidal, square, ramped, and so on, by modulation of the pulse width of the PWM drive signal. Also, as herein used, “in-phase” means that the PWM signal to vaginal vibrator 204 and clitoral vibrator 304 are of like waveform with substantially identical timing. “Out-of-phase” means that the PWM signal to vaginal vibrator 204 and clitoral vibrator 304 are of like waveform but are substantially 180 degrees out of phase. It is further to be noted that the PWM drive signals provided to vaginal vibrator 204 and clitoral vibrator 304 are provided independently of one another. Thus, the PWM waveforms to vaginal vibrator 204 and clitoral vibrator 304 may independently take any shape desired.
Referring now to FIG. 9, and keeping with the exemplary embodiment used in the above description of an exemplary mode of operation of the invention, the timing of various exemplary light source patterns are depicted to provide further detail as to the variety of patterns of light energy emission that may be programmed into controller 501 and memory 502. It can readily be seen that the pattern defined as Base Pattern, for example, causes the blue and infrared LEDs of a light source group to turn ON for 0.25 seconds, after which the blue LED turns OFF for 0.25 seconds while the infrared LED remains ON, and so on. In this manner any number of light source patterns may be defined and programmed into controller 501. Once the patterns have run their course they may repeat. In the examples shown in FIG. 9, five light source patterns are depicted for the exemplary case in which a light source group comprises blue LEDs, red LEDs, and infrared LEDs, in keeping with the exemplary embodiment used in the description of the exemplary mode of operation above. The five exemplary patterns depicted in FIG. 9 are Base Pattern (“BP”); PulseWave Pattern 1 (“PW1”); PulseWave Pattern 2 (“PW2”); PulseWave Pattern 3 (“PW3”); and PulseWave Pattern 4 (“PW4”). Once such patterns are defined and programmed into controller 501 and memory 502, they may be used in combination with vibrator patterns also programmed into controller 501 and memory 502 in order to define further exemplary modes of operation of the invention, as discussed below.
Referring next to FIG. 10, and keeping with the exemplary embodiment used in the above description of an exemplary mode of operation of the invention, the timing of various exemplary vibrator patterns are depicted to provide further detail as to the variety of patterns of vibration that may be programmed into controller 501 and memory 502. It can readily be seen that the pattern defined as Constant, for example, causes the vibrators to operate continuously at a constant power level. In this manner any number of vibration patterns may be defined and programmed into controller 501 and memory 502. Once the patterns have run their course they may repeat. In the examples shown in FIG. 10, six vibration patterns are depicted for the exemplary case in which the invention comprises a vaginal vibrator 204 and a clitoral vibrator 304, in keeping with the exemplary embodiment used in the description of the exemplary mode of operation above. The six exemplary vibrator patterns depicted in FIG. 10 are constant (“C”), In Phase Pulse (“IPP”), Out of Phase Pulse (“OPP”), In Phase Wave (“IPW”), Out of Phase Wave (“OPW”), and Fast Pulse (“FP”). Once such patterns are defined and programmed into controller 501 and memory 502, they may be used in combination with light source patterns also programmed into controller 501 and memory 502 in order to define further exemplary modes of operation of the invention, as discussed below.
Referring now to FIG. 11, another exemplary mode of operation is defined, consistent with the above description of an exemplary mode of operation, for the exemplary embodiment of the invention which both clitoral and vaginal light source groups 302 and 202, respectively, comprise blue LED light sources, red LED light sources, and infrared LED light sources and in which vaginal finger 200 and clitoral finger 300 comprise a vibrator. It is readily seen from FIG. 11 that in the first sixty seconds, both vaginal vibrator 204 and clitoral vibrator 304 operate in a continuous mode at LOW power while vaginal light source group 202 and clitoral light source group 302 operate in pattern PW1 as was defined in FIG. 9. After the first sixty seconds and until 180 seconds have elapsed, both vaginal vibrator 204 and clitoral vibrator 304 operate in a continuous mode at MEDIUM power while vaginal light source group 202 and clitoral light source group 302 operate in pattern PW2 as was defined in FIG. 9. After 180 seconds have elapsed and until 300 seconds have elapsed, both vaginal vibrator 204 and clitoral vibrator 304 operate in a continuous mode at MEDIUM power while vaginal light source group 202 and clitoral light source group 302 operate in pattern PW3 as was defined in FIG. 9. After 300 seconds have elapsed and until 480 seconds have elapsed, both vaginal vibrator 204 and clitoral vibrator 304 operate in a continuous mode at HIGH power while vaginal light source group 202 and clitoral light source group 302 operate in pattern PW4 as was defined in FIG. 9. After 480 seconds have elapsed, both vaginal vibrator 204 and clitoral vibrator 304 operate in a continuous mode at MEDIUM power while vaginal light source group and clitoral light source group operate in pattern PW4 as was defined in FIG. 9. In this exemplary mode of operation, the invention will continue to run in this state until the user powers the invention to an OFF state as defined above, or presses any button which returns the invention to base motor and light patterns, in an alternate embodiment, the invention may time out after a set period of time.
It is not necessary that the vibrators and light sources of the invention operation in the same pattern at the same time; in fact, the great majority of vibrator and light source patterns may comprise different patterns for the vibrators and light sources of the invention as they are all controlled individually by controller 501. It is thus readily seen that any pattern of operation of vibration and light source patterns may be programmed into controller 501 and memory 502.
