Abstract:
Some adult devices are ostensibly marketed to improve female sexual experience female by offering exercises to address relaxed vaginal muscles from birth, age, surgery etc. and for reducing incontinence. However, such devices suffer from variable placement by the user both in terms of orientation and penetrative depth such that the “results” are not reproducible and captured data used to provide feedback to the user and/or providing visual/audible prompts is flawed. Accordingly, it would be beneficial to provide a device with reproducible placement and data for enhancing the usability/benefit of the exercise regimen. It would be further beneficial for the device to either provide this exercise regime as part of a wider assessment of sexual wellness or as part of a sexual stimulation activity thereby reducing the focus on “exercise” to derive the benefits of improved pelvic muscle control.

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This patent application claims the benefit of U.S. Provisional Patent Application 62/050,115 filed Sep. 13, 2014 entitled “Device and Method of Pelvic Floor Muscle Exercise”, the entire contents of which are included by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    This invention relates to adult devices and more particularly to the provisioning of pelvic and sphincter muscle monitoring within devices assessing sexual wellness and/or providing sexual stimulation. 
       BACKGROUND OF THE INVENTION 
       [0003]    A sex toy or adult device is an object or device that is primarily used to facilitate human sexual pleasure which are typically designed to resemble human genitals and may be mechanized and non-mechanized. Mechanized adult devices typically vibrate, although there are examples that rotate, thrust, and even circulate small beads within an elastomeric shell. Non-mechanized adult devices are made from a solid mass of rigid or semi-rigid material in a variety of shapes. Accordingly, today, a wide range of adult devices are offered commercially to users with the majority of them falling into several broad categories including clitoral, (G-spot), dildo, rabbit (generally comprising two vibrators, one phallus-like shaped intended for insertion and a second smaller clitoral stimulator), egg (small smooth vibrators for external or internal stimulation although now offered in a range of shapes), anal, penis ring, bullet (small cylindrical vibrators), c-shaped (for generally hands free use by insertion into the vagina with one or two vibrators for clitoral and/or g-spot stimulation including variants for use during penile penetration) and Butterfly (generally a vibrator with straps). Further, for men there are adult devices with a range of vibrations and movements associated with the penis. 
         [0004]    In addition there are devices such as Kegel balls or Ben-Wa balls which are ostensibly marketed to improve the sexual experience for the female user by offering vaginal muscle exercises to address relaxed vaginal muscles from birth, age, surgery etc. and also to reduce female incontinence. However, these generally include vibrating elements and hence are also categorized under adult devices rather than medical devices. However, such devices are generally subject to variable placement by the user both in terms of orientation and penetrative depth such that the “results” are not reproducible such that the data captured by the software application providing feedback to the user and/or providing visual/audible prompts is flawed. 
         [0005]    Accordingly, it would be beneficial to provide users with a device that provide reproducible placement and accordingly reproducible data for enhancing the usability/benefit of the user following an exercise regimen. It would be further beneficial for the device to either provide the exercise regime as part of a wider assessment of sexual wellness for the user or provide the exercise regime as part of a sexual stimulation activity so that the user does not always have to perform an “exercise” to derive the benefits of improved pelvic muscle control. 
         [0006]    Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.

Such acts or actions may or may not involve the concurrent penetration of a user&#39;s vagina, anus, or mouth and may be male-female, female-female, and solitary female based acts or actions. 
         [0070]    Referring to  FIGS. 1-4  and  8  respectively there are depicted an embodiment of the invention comprising the following components:
       a flexible sleeve, or pillow, which is inserted into the vagina;   a socket; and   an electronics module.       
 
         [0074]    Some embodiments of the invention may include software and/or firmware in conjunction with the hardware to provide the adult device systems, applications, and platforms (ADSAPs) as described and discussed within this specification. 
         [0075]    ADult DEVices (ADDEVs) according to embodiments of the invention exploit a sleeve or pillow is hollow with an air chamber or chambers inside. When the pillow is squeezed, its volume reduces causing a pressure increase. The pillow is attached to the socket via an airtight joint or coupling wherein an airway connects the air in the pillow to air in the socket. Within the socket is a pressure sensor. The socket is made from a low flexibility material so that its volume changes minimally with pressure and accordingly by virtue of being less flexible it changes volume with pressure less than the pillow such that the pillow volume changes dominate in the pressure variations coupled through the airway to the pressure sensor or pressure sensors. For example, the pillow may be formed from a medical grade silicone whilst the socket may be plastic formed, for example, from acrylonitrile butadiene styrene (ABS), low density polyurethane (LDPE), polyvinyl chloride (PVC), polypropylene, polyamides, and polycarbonate. 
         [0076]    The airway connects the chamber in the interior of the socket and may have a single compartment or more than one compartment, with respect to airflow as well as in respect to multiple chambers within the pillow. The use of the airway is novel as it is possible to restrict the airflow from the pillow chamber to the socket and back in a manner that a time constant for two-way airflow is created. This time constant represents an improvement over prior art and, the airway, in some embodiments, behaves as a constricting airway causing the return air from the socket to the pillow to be slowed when the muscles relax, causing a slower rate of return to the original size of the pillow. Advantageously, the pillow-socket arrangement permits complete compression of the pillow during muscle contraction. That is, compared to prior art, the volume reduction of the pillow is not blocked by an incompressible element in the pillow. 
         [0077]    Further, as will become evident in the description below and outlined above the geometry of the pillow has been established in order to provide several key benefits. Considering, an adult device with a pillow for vaginal insertion these benefits include:
       superior positioning within the vagina;   increased comfort for the user;   improved placement consistency within the vagina, which permits more accurate measurement of muscle contractions and more accurate progress measurement;   superior sensitivity to the upper portion of the muscles; and   the asymmetric shape of the adult device provides a superior fit to the muscles as it more accurately matches natural muscle shape.       
 
         [0083]    In addition to the novel shape of the pillow the inventors have established a novel shape of the handle as the adult device may be employed not only by a user personally but also by medical personnel within a clinical environment, doctors surgery etc. Accordingly, the handle is designed for benefits including:
       providing improved comfort to the patient during insertion and removal;   provides improved comfort to the user when using the device;   improving placement control of the adult device for the user;   providing improved placement control for a doctor or therapist, as compared to prior art.       
 
         [0088]    The handle should be large enough for comfort and control, yet light enough to avoid incorrect or inconsistent measurements. The novel shape of the handle provides an improvement over prior art. 
         [0089]    Referring to  FIG. 1  there is depicted a cross-section of an ADult DEVice (ADDEV) according to an embodiment of the invention. The shape of the ADDEV, in numerous embodiments, provides novel improvements over the prior art in terms of fit, convenience, and function. Depicted is a curved line representing device plane  110  which runs along the axis of the device and is, approximately, in the sagittal plane of the user&#39;s body when the device is in use, approximately aligned to the superior-inferior axis of the user within their vagina. Importantly, device plane  110  is not represented by a straight line, or a simple radius curve, as employed within devices in the prior art. Within the embodiment depicted, device plane  110  has a smaller radius near the superior tip  111  of the device, and a larger radius near the inferior end, through the handle  117 . Tip  111  shows the superior top of the device wherein the radius of the tip  111 , which is much smaller than the radii of the upper portion  112  and lower portion  121  for the body of the pillow. The radius of the tip  111  may be less than half, less than a quarter, less than an eighth, or less than a tenth the radius of either the surface of the upper portion  112  or lower portion  121 . The radius of the upper portion  112  defines the upper curve of the pillow which, in this embodiment of the invention, faces the anterior surface of vagina, in use. Within this embodiment of the invention the radius of the upper portion  112  is a smooth joining curve with the curves of the top  111  and upper neck portion  113 , and may not be a uniform radius along its length, as shown. The average radius for upper surface  112  may be in the range of 25 mm to 500 mm (1″ to 20″), or in the range of 50 mm to 250 mm (2″ to 10″), or in the range of 75 mm to 175 mm (3″ to 7″). The concave radius of the upper neck portion  113  defines the change from the primary pillow radius defined by the upper portion  112  to create the neck of the pillow, at or near the minimum diameter of the device. This radius may be in the range of 0 mm to 1000 mm (0″ to 40″), or in the range of 12.5 mm to 500 mm (½″ to 20″). Optionally, another portion of the neck at or adjacent to the radius of upper neck portion  113  may be straight. 
         [0090]    Still referring to  FIG. 1 , upper surface  115  defines the upper surface of the handle, which may be facing the user&#39;s pubic bone, when the device is in use, for the embodiment of the invention for vaginal insertion. This surface may be straight, or have a concave or convex radius larger than 12.5 mm (½″) or larger than 50 mm (2″). This surface may in embodiments of the invention be a concave portion of a sphere or ellipsoid, surface  61  in  FIG. 4 , where the recess created by the shape provides a place for the thumb of the user when inserting or removing the device. The radii of the portion of the sphere are larger than 1,500 m (60″), or larger than 500 mm (20″), or larger than 250 mm (10″), or larger than 125 mm (5″), or in the range of 12.5 mm to 250 mm (½″ to 10″), or in the range of 25 mm to 125 mm (1″ to 5″). The recess in this region, surface  61 , may have two separate radii as in an ellipsoid. 
         [0091]    Continuing with  FIG. 1 , transition surface  116  is a curve at the end of the handle  117 . The radius for this curve may be in the range of 12.5 mm to 250 mm (½″ to 10″). The rear surface of the handle  117  represents the region furthest from the user and may have a radius for this surface is in the range of 25 mm to infinity (1″ to infinity), or in the range of 50 mm to 1,500 mm (2″ to 60″), This surface may be concave or convex and transitions at the lower end to bottom  118  of the handle  117 , which connects the bottom  118  of the handle  117  to the lower portion  114  of the neck of the ADDEV. The radius for this curve may be in the range of 12.5 mm to 500 mm (½″ to 20″). Lower portion  114  is the lower, or posterior neck portion of the device where it mates with the socket. This portion may be straight, or have a concave radius in the range of 25 mm to infinity (1″ to infinity). First and second measurement  119 A and  119 B depict the distance from the minimum diameter of the device at its neck to the junction between the pillow and the socket and the distance from the tip  111  to the junction between the pillow and the socket. The range for this distance can be 0 mm to 150 mm (0″ to 6″), or in the range of 12.5 mm to 75 mm (½″ to 3″). 
         [0092]    The concave surface  120  defines the posterior neck, or minimum diameter of the device, wherein this concave surface  120  may have the same range as upper neck portion  113 , although it may be “smoother” with a larger radius than upper neck portion  113 . Lower portion  121  is the posterior main curve for the pillow and the average radius for this curve may be in the same range as the curve for upper portion  112 , although it may be longer due to the asymmetric shape as defined by device plane  110 . 
         [0093]    Referring further to  FIG. 1 , embodiments of the invention may be defined by none, one or more of the following relationships:
       tip radius  111  is smaller than the radii of upper portion  112  and lower portion  121 ;   lower portion  121  has larger average radius than upper portion  112 ;   transition surface  116  and bottom  118  have smaller radii than the transitionary surface joining them at the rear of the handle  117 ; and   transition surface  116  and bottom  118  have smaller radii than upper surface  115  and lower portion  114 .       
 
         [0098]    Continuing further with  FIG. 1 , the angle of upper surface  15  with respect to the device plane  110 , may be within the range 0° to 90° counterclockwise; or in the range 15° to 75°; or in the range 25° to 60°; or in the range of 30° to 50°. The angle of rear surface of handle  117 , with respect to device plane  110 , may be within the range of 0° to 90° counterclockwise; or in the range 15° to 75°; or in the range 30° to 70°; or in the range of 40° to 60°. Further first and second surfaces  122 A and  122 B are curved surfaces formed roughly in the plane of the drawing. First surface  22 A is cut-away in  FIG. 1 , and not shown. Second surface  122 B shows the rear side of the surface. Surfaces  22 A and  22 B are both concave, and are surrounded generally by upper surface  115 , transition surface  116 , handle  117 , bottom  118  and the bulb. Within some embodiments of the invention  FIG. 1  is to scale whilst in other embodiments of the invention it is not to scale. 
         [0099]      FIG. 2  shows some of the major elements of the device, according to an embodiment of the invention. As depicted there is a tip  131  of the device whilst anterior wall  132  and posterior wall  144  form the pillow with hollow space  143  within it. A recessed key  134  in the pillow mates with the socket key. The pillow mates with socket  136  at pillow-socket joint  135 . Within this are battery  137  which fits within the hollow portion  138  the handle, or socket  136 . A pressure sensor  140  is mounted to a PCB  139  which contains the internal electronics for the ADDEV. Also indicated are end  141  end of the airway  142  at the pressure sensor  140 . Neck  133  of the pillow fits around and is seated upon the  142 . Within some embodiments of the invention  FIG. 2  is to scale whilst in other embodiments of the invention it is not to scale. 
         [0100]    Now referring to  FIG. 3  there is depicted an embodiment of the invention with a sensor  151  deployed in the surface of the pillow connected to the PCB via connector  153  and cable  152 . Accordingly, one or more sensors may be deployed in the surface of the pillow and coupled to the PCB and/or a second PCB via cables. Subsequently, in respect of  FIGS. 12 to 14B  other embodiments of the invention are depicted with sensors which are described below wherein their cabling/connectivity may be within the body of the pillow rather than through the hollow chamber(s) within the pillow. For example,  FIGS. 12 to 14B  may employ a flexible scaffold to which the electrical interconnections and sensors are attached prior to the silicone casing of the ADDEV being formed. 
         [0101]    Referring to  FIG. 4  there is depicted an exploded three dimensional (3D) “blown-out” assembly depicted a method of manufacturing an ADDEV according to an embodiment of the invention. Accordingly, there are depicted:
       PCB  161  which is the internal electronics for interfacing to the pressure sensor(s) and/or other sensor(s) wherein in some embodiments of the invention the PCB also includes a wireless antenna such as a Bluetooth Low Energy (BLE) antenna;   Battery  164  or battery module which may, for example, be sealed within the ADDEV without external connections such that the ADDEV is disposed of once the battery is drained or alternatively there may be an external connection for an electrical power supply to recharge a rechargeable battery  164  or rechargeable battery module;   Pillow  63  is a cut-away cross-section of what would typically be molded as a single piece part although it may in other embodiments of the invention be formed from two portions;   Anterior portion  162  of a shell (scaffold) forming the part of the socket (handle) which together with posterior portion  165  forms the rear held portion of the ADDEV; and   Posterior portion  165  of a shell (scaffold) forming the part of the socket (handle) which together with anterior portion  162  forms the rear held portion of the ADDEV.       
 
         [0107]    Accordingly, the ADDEV may be assembled by placing the PCB  161  and battery  164  within the posterior and anterior portions  162  and  165  which are attached to one another, for example by virtue of being screwed together, glued together, or joined via snap-fit fixturing for example. Then the pillow  163  is attached to the resulting socket. Optionally, an ADDEV may be sold with multiple pillows of the same geometry such that these may be replaced periodically or these may be of different physical dimensions such that the user can select the one that gives them the best fit/comfort and provides appropriate monitoring of the activity of their muscles, e.g. vaginal muscles. Optionally, a vaginal pillow and an anal pillow may be provided allowing a user to perform exercises and monitor muscle activity/progress for both. 
         [0108]    Now referring to  FIG. 5  there is depicted a 3D rendering of an embodiment of the invention wherein the asymmetrical shape is evident both spherically and rotationally. The inventors notes that area  122 A is an elliptical recess, placed conveniently for the thumb, or thumb and index finger of the user as depicted in  FIGS. 6A and 6B  respectively. A second area  122 B is disposed on the other side of the socket and it is evident that the width and height (along and perpendicular to the device plane  110  are larger than the thickness (posterior to anterior distance). This width to thickness ratio is an improvement over prior art in that it permits the user to easily rotationally adjust the ADDEV once inserted. The firm thumb and fingers grip of the handle not only matches a natural orientation of the hand for placement of the device, but also provides easy and firm adjustment of the depth and orientation of the device. Also depicted ate the rear of the handle  117  and the upper surface  115 . 
         [0109]    Referring to  FIG. 6A  there is depicted a typical user grip, with the thumb and index finger grasping the device using upper surface  15  and handle  117 , respectively. Referring to  FIG. 6B  there is depicted what the inventors refer to as a typical physician grip, or that of another user, with the thumb and index finger grasping the device using concave surfaces  122 A and  122 B. 
         [0110]    According to embodiments of the invention there is a narrowing of the neck where the pillow and socket mate which provides for improved comfort and more effective measurements of contractions when a user performs muscle exercises with the ADDEV inserted. Within the prior art, the minimum, average, or maximum compression in this region are too small, either due to a large diameter in this region for designs such as Kegel balls etc. which are typically spherical or ellipsoid in geometry. The diameter according to embodiments of the invention measured from upper neck portion  113  to concave surface  120  (see  FIG. 1 ) may be less 90%, 80%, 70%, 60%, 50%, 45%, 40%, 35%, or 30% of the diameter of the device measured at the largest diameter of the pillow. 
         [0111]    Now referring to  FIG. 7  there are depicted first and second cross-sections A-A and B-B respectively of the socket portion of an ADDEV according to an embodiments of the invention. As noted supra there are elliptical recesses  122 A/ 122 B on the posterior/anterior portions of the socket adapted to a thumb and to one or two opposing fingers. One side of this elliptical recess is shown as  191 . Note that the depth and radius of the two cross-sections A-A and B-B of this recess, shown as cross-sectional views  193  and  192  respectively, are distinctly different. The recess, two opposing recesses, and the elliptical shape of the recess are associated with many embodiments of the invention. The recesses and radii may be as shown in this  FIG. 9 , or be within the range pictured larger or smaller by plus or minus 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 75%, or 90%, as percentages of the size of the socket. Note that the labeling of these cross sections is not consistent with labeling on other Figures. 
         [0112]    It would also be evident that the center of the grip portion of the socket, shown as the recess  191 , is close to the primary axis of the device, shown here and in  FIG. 1  as device plane  110 . The center of the grip recess of the handle may be within 5 mm, 10 mm, 12.5 mm, 20 mm, 25 mm, 38 mm, 50 mm, or 75 mm o(0.2″, 0.5″, 0.8″, 1″, 1.5″, 2″, or 3″) of this axis, device plane  110 , or larger. As noted supra an inventive aspect of ADDEVs according to embodiments of the invention is their asymmetry. Looking towards the tip of an ADDEV according to an embodiment of the invention then the left-right width and shape are distinct compared with the posterior-anterior width and shape. In particular the former is wider than the latter, as measured at the widest portions of the bulb on each axis. Referring now to  FIG. 15  this asymmetry is depicted for an ADDEV according to an embodiment of the invention through three different cross-sections of the pillow, X-X, Y-Y and Z-Z. Note that the labeling of these cross sections is not consistent with labeling on other Figures. 
         [0113]    Within another embodiment of the invention for an ADDEV the cross-section width in the lateral plane may be at least 1.3 times the cross-section width in the ventral-dorsal plane, or the sagittal plane, at cross-sections X-X and Y-Y. Within another embodiment of the invention, at the Y-Y cross section the difference-ratio between the widest and narrowest width at that cross section may be at least 1.05, 1.1, 1.2, 1.3, 1.5, 1.7, 2.0, 2.5, 3.0, 3.5, or 4.0. 
         [0114]    Now referring to  FIG. 9  there is depicted an ADDEV in side view and cross-sectional side-view  900 A and  900 B respectively. As evident from side view  900 A the pillow  930  and socket  920  are augmented with a clitoral portion  910 . As depicted in cross-sectional view  900 B the pillow  930  comprises a single air chamber  950  coupled to a pressure sensor  960  which is connected to a battery  980  and control circuit  970 . The battery  980  being coupled to a power socket  990  allowing the battery  980  to be recharged. Optionally, rather than employing a wireless interface the ADDEV may employ a wired data connection routed through power/data socket  990  such as a micro-USB or Apple™ Lightning for example. Also connected to the controller is vibrating element  940 . Accordingly, the ADDEV depicted in  FIG. 9  may be employed as a vaginal muscle exercise device wherein completion of a predetermined training schedule or activity results in the activation of the vibratory function for the user&#39;s clitoris. Alternatively, the vibratory function of the vibrating element  940  may be activated in response to each muscle flexure or action performed by the user so that the more they exercise within a given session the longer the vibratory element  940  provides stimulation to the user&#39;s clitoris. 
         [0115]    Now referring to  FIG. 10  there is depicted an ADDEV in side view  1000 A together with first and second cross-sectional side-views  1000 B and  1000 C respectively. As evident from side view  1000 A the vaginal pillow  1010  and socket are now augmented with anal pillow  1015  and a larger socket  1020  encompassing two grip regions. As depicted in first cross-sectional view  1000 B the vaginal pillow comprises a single air chamber  1030  coupled to a pressure sensor  1040  which is connected to a battery  1080  and control circuit  1050 . The battery  1080  being coupled to a power socket  1090  allowing the battery  1080  to be recharged. Optionally, rather than employing a wireless interface the ADDEV may employ a wired data connection routed through a power/data socket  1090  such as a micro-USB or Apple™ Lightning for example. The controller  1050  is also coupled to a second circuit  1060  which provides control and power to vibratory element  1070  within the anal portion  1015 . Accordingly, the ADDEV depicted in  FIG. 10  in first cross-section  1000 B may be employed as a vaginal muscle exercise device wherein completion of a predetermined training schedule or activity results in the activation of the vibratory function for the user&#39;s anus. Alternatively, the vibratory function of the vibrating element  1070  may be activated in response to each muscle flexure or action performed by the user so that the more they exercise within a given session the longer the vibratory element  1070  provides stimulation to the user&#39;s anus. 
         [0116]    As depicted in second cross-sectional view  1000 C the vaginal pillow comprises a first air chamber  1035 A coupled to a first pressure sensor  1045 A which is connected to the battery and control circuit as discussed supra in respect of first cross-section  1000 B. However, in this embodiment of the invention the control circuit is also coupled to second pressure sensor  1045 B which is coupled to the second air chamber  1035 B within the anal pillow  1015 . Accordingly, the ADDEV allows a user to perform vaginal and anal muscle training/exercises with a single device. Within embodiments of the invention the vaginal and anal pillows  1010  and  1015  may be the same, similarly or dimensioned differently. Wherein they are dimensioned similarly or the same then through the use of an accelerometer circuit within the ADDEV to determine orientation it is feasible for the user to employ an ADDEV such as depicted in second cross-section  1000 C in either orientation leading to the socket having dual grip elements that are the mirror image of each other. 
         [0117]    Optionally, within another embodiment of the invention the anal pillow may be coupled not only to a pressure sensor but also a fan and partial non-return valve such that the anal pillow can be partially inflated, for example, in response to correct vaginal muscle exercises. The inventors define the term “partial non-return valve” as once the fan stops blowing then the anal pillow  1015  will deflate slowly allowing its removal once it has returned to or close to its original dimensions. Optionally, the non-return valve may be electronically controlled in other embodiments of the invention in conjunction with a mechanical pump. Alternatively, the anal pillow  1015  may be part of a self-contained fluidic actuation and control system within the ADDEV such that a reservoir within the socket provides fluid to inflate elements within the anal pillow or the anal pillow directly. 
         [0118]    Now referring to  FIG. 11  there is depicted an ADDEV in side view  1100 A together with cross-sectional side-view  1100 B respectively. As evident from side view  1100 A the vaginal pillow  1120  and socket are now augmented with anal pillow  1125 , clitoral portion  1110  and a larger socket  1130  encompassing two grip regions. As depicted in first cross-sectional view  1100 B the vaginal pillow comprises a single air chamber  1160  coupled to a pressure sensor integrated with first circuit  1150  which is connected to a battery  1190  and control circuit  1180 . The battery  1190  being coupled to a power socket  1195  allowing the battery  1190  to be recharged. Optionally, rather than employing a wireless interface the ADDEV may employ a wired data connection routed through a power/data socket  1190  such as a micro-USB or Apple™ Lightning for example. The controller  1180  is also coupled to a second circuit  1150  which controls a first vibrating element  1170  and to a second vibrating element  1140  within the clitoral portion  1140  via the first circuit  1150 . Accordingly, it is evident as described supra that the functionality of the first vibrating element  1170  and second vibrating element  1140  may be established in dependence upon a mode of the ADDEV, e.g. sex toy or muscle exerciser, and that within a selected mode the characteristics of the first and second vibrating elements  1140  and  1170  may be adjusted in dependence upon a variety of factors including, but not limited, user input, user progress, clinical or personal use, etc. Further, as discussed below the first and second vibrating elements  1140  and  1170  may be adjusted in dependence upon direct measurements of the user such as sexual arousal, sexual wellness etc. 
         [0119]    Optionally, the ADDEVs depicted in  FIGS. 9 to 11A  may be augmented further by making the pillow to socket connection demountable such that the user can replace, for example, a vaginal exerciser pillow with a 150 mm (6″) Gräfenberg spot (G-spot) vibrator or the anal exerciser pillow can be replaced with a 75 mm long by 50 mm diameter butt plug. Such a reconfigurable ADDEV is depicted within  FIG. 11B  wherein mountable to the socket  1100 C are:
       straight dildo/vibrator element  1100 D;   curved G-spot dildo/vibrator element  1100 E;   “large” pillow  1100 F;   “small” pillow  1100 G;   “thin long” pillow  1100 H; and   butt plug  11001 .       
 
         [0126]    It was briefly discussed supra in respect of  FIG. 3  that additional sensors may be integrated with an ADDEV according to an embodiment of the invention. Referring to  FIGS. 12 to 14A  there are depicted examples of additional sensors relating to sexual wellness and/or sexual arousal determination. Accordingly referring to  FIG. 12  with first and second cross-sections  1200 A and  1200 B respectively there are depicted deployment scenarios in respect of labial thermistors wherein increased blood flow to the labia results in an increase in the temperature of the labia which via the temperature dependent resistance of the thermistors can be monitored. Accordingly, in first cross-section  1200 A first and second labial thermistors  1210  and  1220  are disposed within the region of the pillow-socket coupling for a discrete pillow device whereas in second cross-section  1200 B third and fourth labial thermistors  1230  and  1240  are depicted within a device such as those depicted within  FIGS. 9 and 11A  respectively wherein labial thermistor  1230  is extended around the surface of the ADDEV for improved coupling the upper pelvic region between their clitoris and vagina. Fourth labial thermistor  1240  is depicted on the lower edge of the user&#39;s vaginal opening. Optionally, the thermistors may be disposed on the sides of the ADDEV elements rather than the surfaces directly in engagement with the user&#39;s body. Accordingly, as the user uses their ADDEV for sexual stimulation and/or vaginal exercises their labial temperature can be monitored for an indication of sexual arousal allowing adjustment of control program parameters, control settings, feedback from vaginal exercise etc. Optionally, extended monitoring of the user&#39;s labial temperature discretely or in conjunction with other biometric data may allow automatic determination of the user&#39;s menstrual cycle and subsequent projections as to the user&#39;s menstrual cycle from recent temperature trend data correlated to historical data. Optionally, the user may enter data to align the acquired data with their menstrual cycle. Optionally, within other embodiments of the invention the thermistor may be replaced by another element with an electrical characteristic that is temperature dependent such as resistance, inductance, or capacitance for example. 
         [0127]    Now referring to  FIG. 13  there are depicted with first and second cross-sections  1300 A and  1300 B respectively there are depicted deployment scenarios in respect of optical sensor elements for determining, for example, labial and vaginal blood flow using photoplethysmography (PPG) and/or laser Doppler imaging (LDI). Accordingly, in first cross-section  1200 A first to third Optical Source and Detector (OSAD) pairs  1310  to  1330  are depicted disposed within the pillow of a discrete pillow device. As depicted first OSAD pair  1310  is towards the upper vaginal opening on the pillow-socket region of the ADDEV, second OSAD pair  1320  towards the cervix at the tip of the pillow and third OSAD pair  1330  on the lower vaginal wall within the pillow. In second cross-section  1300 B fourth and fifth OSAD pairs  1340  and  1350  are depicted within a device such as those depicted within  FIGS. 9 and 11A  respectively wherein the fourth and fifth OSAD pairs  1340  and  1350  are within the extended socket surface of the ADDEV for improved coupling the upper pelvic region between their clitoris and vagina and lower pelvic region between vagina and anus. Within PPG exploiting a reflective mode as depicted the volume of blood is determined in dependence upon the intensity of the reflected whilst each cardiac cycle appears as a peak within the reflected signal. As blood flow to the skin can be modulated by multiple other physiological systems, PPG can also be used to monitor breathing (respiration), medication effects, hypovolemia, and other circulatory conditions, especially where extended monitoring under a variety of conditions including rest and/or sleep provide enhanced baseline and/or early data. For example, the height of AC component of the PPG is proportional to the pulse pressure, the difference between the systolic and diastolic pressure in the arteries. Additionally, the shape of the PPG waveform differs from subject to subject, and varies with the location, providing additional options such as identification of user through PPG data and automatic adjustment of the ADDEV parameters/control program etc. in response therefrom. 
         [0128]    Alternatively, the OSAD pair may be employed for laser Doppler imaging (LDI) wherein the OSAD is typically an infrared laser source in conjunction with a photodetector rather than a visible LED and photodetector in the instance of PPG. Accordingly, the pulsed laser light interacts with moving blood cells such that a small portion of it is reflected with a frequency shift, detected, and converted into an electrical signal. LDI can provide a direct measure of female sexual response in that it does not require physical contact and the signals are typically acquired at depth of 2-3 mm (approx. ⅛″) below the skin surface. It would be evident that one, two or more OSAD pairs may be employed and that their position may vary according to the design of the ADDEV and/or pillow including, for example, laterally disposed on the ADDEV or disposed in respect of the clitoris, etc. 
         [0129]    Now referring to  FIG. 14A  there is depicted a pillow for an ADDEV according to an embodiment of the invention wherein multiple electrical contacts are disposed. As depicted there are first to third contact pairs  1410 / 1440 ;  1420 / 1430 ; and  1450 / 1460  of electrical contacts (ELCOs) connected to circuit  1480 . It would be evident that one, two or more ELCO pairs may be employed and that their position may vary according to the design of the ADDEV and/or pillow including, for example, laterally disposed on the ADDEV or disposed in respect of the clitoris, etc. Equally, an array of ELCOs may be employed as well as a discrete ELCO and/or spatially separated ELCO pair(s). An ELCO may be employed to measure electrical activity and/or provide electrical stimulation to the user&#39;s vagina/anus/clitoris according to the design of the ADDEV and their disposition on the ADDEV. Accordingly, the device may provide electrostimulation of the vaginal muscles with part of an exercise/training regime and then determine from user flexing the muscle strength/range of motion etc. 
         [0130]    Within an alternate embodiment of the invention one or more of the ELCO elements may be replaced with a microphone such as one based upon capacitive thin film or microelectromechanical systems (MEMS) transducer, a piezoelectric transducer, accelerometer, hydrophone, or another type of microphone in order to measure the acoustic output of a contracting muscle. Accordingly, based upon such microphone placement an ADDEV according to an embodiment of the invention may support acoustic myography (AMG) of the pubococcygeus muscle and/or other of the pelvic floor muscles. Beneficially, the pillow geometry enhances/assures contact of one or more microphone to an inner surface of the vagina or the cervix. Typically, AMG has a frequency range of interest that is primarily 5-50 Hz, although there is value beyond this range which beneficially are captured by the microphone sensor, particularly, in the upper portion of this frequency range, whilst the pressure sensor detects a lower portion of the frequency range. Within other embodiments of the invention the microphone may be reversed to function as a loudspeaker or a dedicated loudspeaker element may be provided such that the ADDEV provides acoustic stimulation directly such as that derived from music, video, broadcast television, multimedia etc. 
         [0131]    Within the embodiments of the invention described and depicted in respect of  FIGS. 1 to 14A  the pillow has been depicted with a single chamber. However, it would be evident that the chamber may in other embodiments of the invention be partitioned through flexible and/or inflexible membranes. An example of such a multi-chamber pillow is depicted in  FIG. 14B  wherein the pillow  1490  is divided into four chambers  1470 A to  1470 D which are depicted as upper rear/upper front/lower rear and lower front respectively. However, within other embodiments of the invention the chambers may be “radially” positioned such as quadrants of the length of the pillow or simply upper/lower of upper/lower/tip etc. 
         [0132]    Within the descriptions supra in respect of  FIGS. 1 to 14B  ADDEVs according to embodiments of the invention have been described with respect to providing simulation and assessment of a user&#39;s vagina and/or anus and/or clitoris. Electrical control and monitoring have been described together with wired and wireless data connectivity of the ADDEV to the external world. Accordingly, the ADDEV may be wirelessly connected to a user&#39;s PED or FED such as depicted in  FIG. 16  and access/post content/data to one or more local and/or remote servers associated with different aspects of the user including, but not limited to, their personal ADDEV profile, personal health records, other PEDs/FEDs/wearables, physician&#39;s office, etc. Accordingly, the network interconnectivity and structure of a network supporting ADDEVs according to embodiments of the invention are described in respect of  FIG. 15  whilst the local device structure, PED/access point (AP) association and network connectivity are described and depicted in respect of  FIG. 16 . 
         [0133]    Referring to  FIG. 15  there is depicted a network environment  1500  within which embodiments of the invention may be employed supporting ADDEV systems, applications, and platforms (ADSAPs) according to embodiments of the invention. Such ADSAPs, for example supporting multiple channels and dynamic content. As shown first and second user groups  1500 A and  1500 B respectively interface to a telecommunications network  1500 . Within the representative telecommunication architecture a remote central exchange  1580  communicates with the remainder of a telecommunication service providers network via the network  1500  which may include for example long-haul OC-48/OC-192 backbone elements, an OC-48 wide area network (WAN), a Passive Optical Network, and a Wireless Link. The central exchange  1580  is connected via the network  1500  to local, regional, and international exchanges (not shown for clarity) and therein through network  1500  to first and second cellular APs  1595 A and  1595 B respectively which provide Wi-Fi cells for first and second user groups  1500 A and  1500 B respectively. Also connected to the network  1500  are first and second Wi-Fi nodes  1510 A and  1510 B, the latter of which being coupled to network  1500  via router  1505 . Second Wi-Fi node  1510 B is associated with Enterprise  1560 , such as Adam &amp; Eve™ for example, within which other first and second user groups  1500 A and  1500 B are disposed. Second user group  1500 B may also be connected to the network  1500  via wired interfaces including, but not limited to, DSL, Dial-Up, DOCSIS, Ethernet, G.hn, ISDN, MoCA, PON, and Power line communication (PLC) which may or may not be routed through a router such as router  1505 . 
         [0134]    Within the cell associated with first AP  1510 A the first group of users  1500 A may employ a variety of PEDs including for example, laptop computer  1555 , portable gaming console  1535 , tablet computer  1540 , smartphone  1550 , cellular telephone  1545  as well as portable multimedia player  1530 . Within the cell associated with second AP  1510 B are the second group of users  1500 B which may employ a variety of FEDs including for example gaming console  1525 , personal computer  1515  and wireless/Internet enabled television  1520  as well as cable modem  1505 . First and second cellular APs  1595 A and  1595 B respectively provide, for example, cellular GSM (Global System for Mobile Communications) telephony services as well as 3G and 4G evolved services with enhanced data transport support. Second cellular AP  1595 B provides coverage in the exemplary embodiment to first and second user groups  1500 A and  1500 B. Alternatively the first and second user groups  1500 A and  1500 B may be geographically disparate and access the network  1500  through multiple APs, not shown for clarity, distributed geographically by the network operator or operators. First cellular AP  1595 A as show provides coverage to first user group  1500 A and environment  1570 , which comprises second user group  1500 B as well as first user group  1500 A. Accordingly, the first and second user groups  1500 A and  1500 B may according to their particular communications interfaces communicate to the network  1500  through one or more wireless communications standards such as, for example, IEEE 802.11, IEEE 802.15, IEEE 802.16, IEEE 802.20, UMTS, GSM 850, GSM 900, GSM 1800, GSM 1900, GPRS, ITU-R 5.138, ITU-R 5.150, ITU-R 5.280, and IMT-1000. It would be evident to one skilled in the art that many portable and fixed electronic devices may support multiple wireless protocols simultaneously, such that for example a user may employ GSM services such as telephony and SMS and Wi-Fi/WiMAX data transmission, VOIP and Internet access. Accordingly portable electronic devices within first user group  1500 A may form associations either through standards such as IEEE 802.15 and Bluetooth as well in an ad-hoc manner. 
         [0135]    Also connected to the network  1500  are Social Networks (SOCNETS)  1565 , ADDEV manufacturer  1570 A, e.g. We-Vibe™ by Standard Innovation Corporation; online retailer  1570 B, e.g. Amazon™; online personals website  1570 C, e.g. PinkCupid™; online chat/discussion/bulletin board/forum  1570 D, e.g. www.sexforums.com; adult multimedia content website  1575 A, e.g. RedTube™; and multimedia content website  1575 B, e.g. iTunes™; as well as first and second servers  1590 A and  1590 B which together with others, not shown for clarity. Accordingly, a user employing one or more ADSAPs may interact with one or more such providers, enterprises, service providers, retailers, third parties etc. and other users. First and second servers  1590 A and  1590 B may host according to embodiments of the inventions multiple services associated with a provider of ADDEV systems, applications, and platforms (ADSAPs); a provider of a SOCNET or Social Media (SOME) exploiting ADSAP features; a provider of a SOCNET and/or SOME not exploiting ADSAP features; a provider of services to PEDS and/or FEDS; a provider of one or more aspects of wired and/or wireless communications; an Enterprise  1560  exploiting ADSAP features; license databases; content databases; image databases; content libraries; customer databases; websites; and software applications for download to or access by FEDs and/or PEDs exploiting and/or hosting ADSAP features. First and second primary content servers  1590 A and  1590 B may also host for example other Internet services such as a search engine, financial services, third party applications and other Internet based services. 
         [0136]    Accordingly, a user may exploit a PED and/or FED within an Enterprise  1560 , for example, and access one of the first or second primary content servers  1590 A and  1590 B respectively to perform an operation such as accessing/downloading an application which provides ADSAP features according to embodiments of the invention; execute an application already installed providing ADSAP features; execute a web based application providing ADSAP features; or access content. Similarly, a user may undertake such actions or others exploiting embodiments of the invention exploiting a PED or FED within first and second user groups  1500 A and  1500 B respectively via one of first and second cellular APs  1595 A and  1595 B respectively and first Wi-Fi nodes  1510 A.

Network devices  1607  may be coupled to AP  1606  via any combination of networks, wired, wireless and/or optical communication links such as discussed above in respect of  FIG. 15  as well as directly as indicated. Network devices  1607  are coupled to network  1500  and therein Social Networks (SOCNETS)  1565 , ADDEV manufacturer  1570 A, e.g. We-Vibe™ by Standard Innovation Corporation; online retailer  1570 B, e.g. Amazon™; online personals website  1570 C, e.g. PinkCupid™; online chat/discussion/bulletin board/forum  1570 D, e.g. www.sexforums.com; adult multimedia content website  1575 A, e.g. RedTube™; and multimedia content website  1575 B, e.g. iTunes™. 
         [0138]    The electronic device  1604  includes one or more processors  1610  and a memory  1612  coupled to processor(s)  1610 . AP  1606  also includes one or more processors  1611  and a memory  1613  coupled to processor(s)  1610 . A non-exhaustive list of examples for any of processors  1610  and  1611  includes a central processing unit (CPU), a digital signal processor (DSP), a reduced instruction set computer (RISC), a complex instruction set computer (CISC) and the like. Furthermore, any of processors  1610  and  1611  may be part of application specific integrated circuits (ASICs) or may be a part of application specific standard products (ASSPs). A non-exhaustive list of examples for memories  1612  and  1613  includes any combination of the following semiconductor devices such as registers, latches, ROM, EEPROM, flash memory devices, non-volatile random access memory devices (NVRAM), SDRAM, DRAM, double data rate (DDR) memory devices, SRAM, universal serial bus (USB) removable memory, and the like. 
         [0139]    Electronic device  1604  may include an audio input element  1614 , for example a microphone, and an audio output element  1616 , for example, a speaker, coupled to any of processors  1610 .

Electronic device  1604  also includes a keyboard  1615  and touchpad  1617  which may for example be a physical keyboard and touchpad allowing the user to enter content or select functions within one of more applications  1622 . Alternatively the keyboard  1615  and touchpad  1617  may be predetermined regions of a touch sensitive element forming part of the display within the electronic device  1604 . The one or more applications  1622  that are typically stored in memory  1612  and are executable by any combination of processors  1610 . Electronic device  1604  also includes accelerometer  1660  providing three-dimensional motion input to the process  1610  and GPS  1662  which provides geographical location information to processor  1610 . 
         [0140]    Electronic device  1604  includes a protocol stack  1624  and AP  1606  includes a communication stack  1625 . Within system  1600  protocol stack  1624  is shown as IEEE 802.11 protocol stack but alternatively may exploit other protocol stacks such as an Internet Engineering Task Force (IETF) multimedia protocol stack for example. Likewise AP stack  1625  exploits a protocol stack but is not expanded for clarity. Elements of protocol stack  1624  and AP stack  1625  may be implemented in any combination of software, firmware and/or hardware. Protocol stack  1624  includes an IEEE 802.11-compatible PHY module  1626  that is coupled to one or more Tx/Rx &amp; Antenna Circuits  1628 , an IEEE 802.11-compatible MAC module  1630  coupled to an IEEE 802.2-compatible LLC module  1632 . Protocol stack  1624  includes a network layer IP module  1634 , a transport layer User Datagram Protocol (UDP) module  1636  and a transport layer Transmission Control Protocol (TCP) module  1638 . Protocol stack  1624  also includes a session layer Real Time Transport Protocol (RTP) module  1640 , a Session Announcement Protocol (SAP) module  1642 , a Session Initiation Protocol (SIP) module  1644  and a Real Time Streaming Protocol (RTSP) module  1646 . Protocol stack  1624  includes a presentation layer media negotiation module  1648 , a call control module  1650 , one or more audio codecs  1652  and one or more video codecs  1654 . Applications  1622  may be able to create maintain and/or terminate communication sessions with any of devices  1607  by way of AP  1606 . 
         [0141]    Typically, applications  1622  may activate any of the SAP, SIP, RTSP, media negotiation and call control modules for that purpose. Typically, information may propagate from the SAP, SIP, RTSP, media negotiation and call control modules to PHY module  1626  through TCP module  1638 , IP module  1634 , LLC module  1632  and MAC module  1630 . It would be apparent to one skilled in the art that elements of the electronic device  1604  may also be implemented within the AP  1606  including but not limited to one or more elements of the protocol stack  1624 , including for example an IEEE 802.11-compatible PHY module, an IEEE 802.11-compatible MAC module, and an IEEE 802.2-compatible LLC module  1632 . The AP  1606  may additionally include a network layer IP module, a transport layer User Datagram Protocol (UDP) module and a transport layer Transmission Control Protocol (TCP) module as well as a session layer Real Time Transport Protocol (RTP) module, a Session Announcement Protocol (SAP) module, a Session Initiation Protocol (SIP) module and a Real Time Streaming Protocol (RTSP) module, media negotiation module, and a call control module. Portable and fixed electronic devices represented by electronic device  1604  may include one or more additional wireless or wired interfaces in addition to the depicted IEEE 802.11 interface which may be selected from the group comprising IEEE 802.15, IEEE 802.16, IEEE 802.20, UMTS, GSM 850, GSM 900, GSM 1800, GSM 1900, GPRS, ITU-R 5.138, ITU-R 5.150, ITU-R 5.280, IMT-1000, DSL, Dial-Up, DOCSIS, Ethernet, G.hn, ISDN, MoCA, PON, and Power line communication (PLC). 
         [0142]    Also depicted is ADult DEVice (ADDEV)  1670  which is coupled to the electronic device  1604  through a wireless interface between Antenna  1672  and Tx/Rx &amp; Antenna Circuits  1628  wherein the electronic device  1604  may support, for example, a national wireless standard such as GSM together with one or more local and/or personal area wireless protocols such as IEEE 802.11 a/b/g WiFi, IEEE 802.16 WiMAX, and IEEE 802.15 Bluetooth for example. The Antenna  1672  is connected to Processor  1674  and therein to Memory  1676 , Drivers  1678 , and Features  1680 . Accordingly, the ADDEV  1670  may operate as standalone device with factory installed control routines accessed through an interface on the ADDEV  1670 , not shown for clarity, or through an application in execution upon the electronic device  1604 . Subsequently, as described below one or more of these control routines may be modified, amended, deleted etc. whilst other new control routines may be created, acquired, installed etc. 
         [0143]    Accordingly it would be evident to one skilled the art that the ADDEV  1670  with associated electronic device  1604  may accordingly download original software and/or revisions for a variety of functions supported by the drivers  1678  and/or features  1680 . In some embodiments of the invention the functions may not be implemented within the original as sold ADDEV  1670  and are only activated through a software/firmware revision and/or upgrade either discretely or in combination with a subscription or subscription upgrade for example. 
         [0144]    Within the process of determining pelvic floor muscle pressure measurements the user&#39;s body position has two impacts. First, the neutral, or relaxed, pressure in the device varies by body position. Second, the maximum pressure for a given muscle strength also varies by body position. Thus, accurate measurements and consistent tracking of performance improvement requires either knowing the user&#39;s body position, or requires that the user perform all exercises in the same body position. Determining body position is beneficial and may be established through the employment of an accelerometer or accelerometers within the ADDEV. 
         [0145]    In other embodiment, the accelerometer may be used to determine improper exercise technique, such as the use of incorrect muscles, or additional muscles, or a wrong position of the device or the user. In another embodiment, the accelerometer is used to determine pelvic lift with contractions which where automatically determined represents an advancement over the prior art. Within embodiments of the invention a representation of the user&#39;s body position may be provided to a FED/PED together with a target body position allowing the user to achieve the required posture/position for the exercise. These depictions of user and target positions may adjust in real time. Similarly, the user may be presented via a PED/FED with a depiction of the user&#39;s pelvic floor lift which again may be tracked/monitored/displayed in real time. 
         [0146]    In other embodiments, an accelerometer may be used to detect and monitor exercises other than pelvic floor muscle exercises (commonly referred to as Kegel exercises or Kegels), such as leg lifts, hip raises, crunches, oblique crunches, adductor contractions, other core exercises, and other exercises. 
         [0147]    Within embodiments of the invention the ADDEV contains one or more sensors including, but not limited to, accelerometer, thermometer, LDI, PPG, and a microphone. This or these may be employed to determine heart rate, menstrual cycle, amount of exercise, changes in physical activity level during an exercise session. Optionally, additional sensors such as a humidity sensor may be incorporated into the device or additional biometric data may be acquired through an aggregator ADSAP such as the user&#39;s smart phone for example communicating with the ADDEV and one or more wearable devices. Accordingly, the ADSAP and/or ADDEV can establish whether the user is performing activities such as showering when using the ADDEV as well as detecting cleaning, with the option of powering down the ADDEV in either instance. 
         [0148]    In some embodiments of the invention, various detections, determinations, tracking and storage of aspects and parameters, as discussed herein, are executed wholly or partially internally in the ADDEV; in other embodiments they are executed wholly or partially in a wirelessly connected standard user interface running software as part of this embodiment; in yet another embodiment they are executed whole or partially by software running remotely upon remote servers or “in the cloud” as colloquially known. In other embodiments the user may be prompted through such a wirelessly connected standard user interface to perform one or more specific actions in isolation and/or in combination with a view to improving or mitigating an aspect of the user&#39;s physiological and/or sexual wellness. 
         [0149]    In some embodiments of the invention, current exercise parameters and the user&#39;s performance/progress are sent to a doctor, trainer or therapist in real-time and/or periodically. In some embodiments of the invention the doctor, trainer or therapist may concurrently within a communication link, such as a phone call, in the reverse direction provide human, personalized instruction, communication, status, or motivation to the user. 
         [0150]    In some embodiments of the invention, current exercise parameters are sent to software in the cloud in real-time; while concurrently a communication link, such as a phone call or browser-based data, in the reverse direction from the cloud software to the user, provides automated, personalized instruction, communication, status, or motivation to the user. Such information from the cloud to the user may include information about the status or progress of other users. Alternatively, based upon the users historical data and their current performance/activity a remote automated analysis and control application may adjust settings within an ADSAP directing the user to perform specific actions and/or exercise and/or direct the user to perform a different exercise regime. Optionally, the user&#39;s progress with respect to vaginal muscle control etc. may be correlated with other sexual activity data derived from one or more ADDEVs and/or user&#39;s feedback/social media/etc. 
         [0151]    In one embodiment, a “pairing code” may be used to enable wireless pairing or a communication link. This paring code may be used for setup, such as with Bluetooth or Bluetooth Low Energy (BLE), or may function as a password for regular or repetitive connectivity. Such a pairing code may comprise a tap sequence, shake sequence, squeeze sequence, orientation of the device, or any combination. Note that any such squeezing may be done by the user&#39;s hand, prior to insertion, or by the user&#39;s pelvic floor muscles after insertion. Such a pairing code may be used to insure privacy of the user&#39;s data. Such protected data may be in the device, in a user interface device, in the cloud, or in any combination. In some embodiments of the invention the user&#39;s interface device displays a “challenge”, a sequence of actions, such as taps, shacks or orientation, which the user must then perform as a “response” with the device, to enable pairing or the enabling of some application functionality. 
         [0152]    Within some embodiments of the invention, simply using the device intra-vaginally/intra-anally turns the device on from a sleep mode and launches a corresponding ADSAP on the user&#39;s interface device, e.g. a paired PED and/or FED. Since ideally exercises are recommended multiple times a day, such automatic operation of both the device and a corresponding application through detecting an action within a sleep mode or predetermined time of day/time period since last use etc. significantly ease the use of the ADDEV. Further, referring to  FIG. 17  with a low profile self-contained ADDEV the user may receive triggers to perform exercises and perform them without explicitly activating the ADSAP etc. For example, the ADSAP may “hidden” on the user&#39;s PED user interface and provide discrete prompts and/or texts for example. During exercise sequences the user may be provided with an icon that flashes to indicate perform an exercise or may alternatively select to receive an audible prompt via wired and/or wireless connected headphones. Within other embodiments of the invention the ADSAP may be linked to a thin client version installed on a user&#39;s FED so that whilst at work they can perform the exercise discretely without requiring access to their PED. 
         [0153]    Similarly referring to  FIG. 17  there are depicted first and second views  1700 A and  1700 B of an ADDEV according to an embodiment of the invention wherein the ADDEV supports extended use by virtue of its low profile, low power consumption, and small external geometry. As depicted in first view  1700 A the device comprises a pillow  1710  connected to a low profile socket that contains pressure sensor  1725 , PCB  1720 , battery  1740  and antenna  1730 . The device is completely self-contained and the inventors have demonstrated embodiments of the invention exploiting low profile button cell batteries, such as a 3V IEC standard 60086 compliant button with approximately 200 mAh capacity, with operation over a period of 12 months. Accordingly, as depicted in second image  1700 B the ADDEV  1700  by virtue of exploiting button cells with dimensions of 20 mm diameter and 3 mm thick (0.8″×0.125″) can therefore be very compact and be worn. As depicted in legs-open depiction in second image  1700 B the device  1700  is depicted inserted and projecting down towards the user&#39;s anus  1750  and fitting within their labia majora  1760 . Accordingly, the device  1700  leaves uncovered the user&#39;s urethral opening  1770  and clitoris  1780 . 
         [0154]    In some embodiments of the invention, the user&#39;s device measures radio signal strength from the device, such as Received Signal Strength measurements, to determine an approximate distance between the device and the user&#39;s interface device. This determined distance may then be used to change the user&#39;s interface device parameters, such as volume, type of display, or disabling of feedback entirely. In some embodiments of the invention, such distance determination may be used to initiate or encourage initiation of an exercise. For example, such initiation may be accomplished by simply placing the device next to the user&#39;s smart phone. 
         [0155]    In some embodiments of the invention the ADDEV stores data so that the device may be used effectively and repeatedly without any communications connection. Then, later, if the ADDEV establishes communication, the stored data is then communicated from the ADDEV so as to have a complete record outside the ADDEV of exercise data and history. 
         [0156]    Now referring to  FIG. 18  there are depicted first to tenth screenshots of a user interface presented by a software application upon a PED (or optionally FED) such as Electronic Device  1604  in  FIG. 16 . Accordingly, the adult device software application (ADSoAp) allows the user to establish, for example, one or more profiles for the ADDEV, one or more profiles for themselves, and establish-monitor-track progress towards sexual wellness. However, as evident from first to fourth screens  1810  to  1840  the ADSoAp also provides the user with a calibration process for the ADDEV which may involve solely use within the intended orifice(s) or it may include actions performed by the user external to the intended orifice(s) such as an initial “at rest” calibration and a calibration wherein the user flattens the pillow with their hands or another weight to establish essentially full scale reading. Optionally, the user may be asked to pinch the device between finger and thumb, for example. Accordingly, first to fourth screens  1810  to  1840  depict:
       First screen  1810  wherein the user is within a calibration routine and is asked to squeeze to a comfortable point (with the ADDEV) inserted;   Second screen  1820  wherein the user is subsequently presented with a timer relating to how long they need to squeeze;   Third careen  1830  indicating a successful calibration step completed; and   Fourth screen  1840  indicating an unsuccessful calibration step.       
 
         [0161]    Subsequently in use the user is presented with a series of screens relating to potential exercises, current exercises, etc. as known within the prior art. Examples of exercise user interface screens are depicted in fifth to eighth screens  1850  to  1880  respectively, wherein:
       Fifth screen  1810  wherein the user is ready to exercise and is presented with a countdown;   Sixth screen  1860  wherein the user is subsequently presented with a display for an exercise indicating their current “squeezing” against a target;   Seventh careen  1870  wherein the user is subsequently presented with a display for a successful “rep” (sequence of “squeeze” and relax) exercise indicating that they must “squeeze” within a range and hold; and   Eighth screen  1880  wherein the user is presented with a display for another exercise indicating that they must “squeeze” within a range and hold.       
 
         [0166]    It would be evident that the display format presented within first to eighth images  1810  to  1880  allows for concurrent display of readings derived from multiple sensors within multiple chambers and that the target may be modified to reflect where the user should focus attention and develop more control over their muscles, for example, between left/right; top/bottom and front/back. Other sensor data such as heart rate, blood pressure, blood flow, oxygenation etc. can be presented on the display with formats as known within the art. Ninth screen  1890  depicts a summary screen presented to a user with derived physical data such as an indication of strength (in kilopascal, kp, in this instance) whilst tenth screen  1895  presents temporally depicted pressure information. Optionally, the screens depicting the user&#39;s exercise may include schematics of the user&#39;s anatomy to help them visualize what they are doing and may include these in animated format such that the user receives visual indication of what they have done in addition to simply a number on a screen. 
         [0167]    Whilst within the preceding Figures the body of the insertable portion has not been described or depicted in a large amount of detail it would be evident that portions of the ADDEVs not exploiting a compressible pillow, such as an anal vibrator, clitoral stimulator etc. may be similarly constructed and shaped as one or more prior art dildos and/or vibrators or other ADDEVs. The outer surface of the insertable portion of the ADDEV may be smooth, contoured, grooved, ribbed, and/or comprise bumps and/or nubbies. Optionally, the contours may extend further across the upper surface of the adult device or they may be more centrally limited. Optionally, the depth, spacing, and number of grooves may vary as well as their surface profile from symmetric to asymmetric etc. Optionally, the upper surface may be smooth or it may be profiled by the distribution of nubbies across upper surface regions in some embodiments of the invention. Within others features that have multiple “fingers” or “fronds” may be employed to provide different sensations. Optionally different regions of the ADDEV may have different structures such as nubbies, grooves, smooth areas etc. on the upper central bump as well as its sides. 
         [0168]    The adult device may be provided in a range of physical sizes overall exploiting the relative dimensions and radii etc. described supra in respect of  FIGS. 1 to 4  such that, for example, the length of the inserted vaginal portion may be 50 mm, 75 mm, 100 mm, 125 mm, 150 mm, or 200 mm for example (3″, 4″, 5″, 6″ or 8″) and it&#39;s lateral dimensions may be, for example, 15 mm, 25 mm, 35 mm, 40 mm, 50 mm, or 75 mm (0.6″, 1″, 1.4″, 1.6″, 2″, or 3″). Where an anal insertion element is provided its length and lateral dimensions may be over a similar range as the vaginally inserted portion. Whilst typically the vaginally inserted portion will have limited width variations along its length an anally inserted portion may have larger width variations and may have a length/width ratio lower than the vaginally inserted portion. However, other dimensions, aspect ratios, cross-section geometries etc. may be employed without departing from the scope of the invention. 
         [0169]    Typically, the construction of an ADDEV such as depicted within embodiments of the invention described in respect of  FIGS. 1 to 17  will employ a central scaffold which provides rigidity to the ADDEV in those regions requiring it which may be surrounded by a shell and then a casing. Whilst the casing and shell may be transparent or semi-transparent over portions or all of the ADDEV it is common for the ADDEV to be opaque. Within those regions of the ADDEV that are flexible, such as the pillow, for example, the structure may have no scaffold or it may employ a scaffold that has properties commensurate with that portion of the ADDEV. For example, within the pillow for providing dividing sections between chambers the scaffold may be formed from an elastic material on a frame embedded within the pillow walls such that the dividing section maintains its profile as the pillow expands and contracts. The pillow may be formed in multiple steps according to its profile, thickness, etc. 
         [0170]    An outer casing may be coloured based upon skin colour tones based upon ethnicity or personal preference, e.g. Caucasian, Negroid, Mongol, light, dark, etc. as well as single colour, binary colour, multiple colour etc. According to the complexity acceptable then the outer casing may be formed from a variety of colours and/or be patterned for a specific design. Typically, such colours will be part of a silicone or other elastomer employed in forming the casing although in other embodiments of the invention the casing may be coloured once formed and a protective fluid proof, non-toxic, non-abrasive coating formed atop these applied colours. Such instances of applied colours may include metallic lacquers, particulate lacquers for “sparkle”, etc. Optionally, the silicone may be clear and either embedded into the silicone or a shell of the adult device are LEDs, such as multi-colour LEDs for example, allowing the colour of the adult device to be varied either statically or dynamically, such as for example in response to commands from an associated PED generated in response to controlling ambient light, music, audiovisual content etc. Beneficially, medical grade silicone is clear thereby removing the requirement for any additional coating (e.g. food grade urethane) in conjunction with pigmented silicones. Accordingly, an adult device may with medical grade silicone be clear and formed from an initial sticky soft silicone, e.g. 20 durometer, with a micro-layer (spray coated for example) of high durometer medical grade silicone, for example 70-90 durometer, to create “slippery” surface and avoid silky smooth surface that typically requires use of urethane coating. 
         [0171]    Typically, the casing for the ADDEV will be formed from a non-toxic, hypoallergenic silicone to provide a safe smooth surface although some regions of the ADDEV may be coated, textured and/or finished with a variation from that of the remainder of the casing in order to enhance or promote retention of the ADDEV against the user&#39;s skin or clothing. Typically, the outer surface of the casing will be formed to provide low friction as well as resistance to lubricants that may or may not be employed. According to the casing material and sealing of the device then it may be cleaned or sterilized to a medical standard, for example through a domestic dishwasher cycle. Alternatively, the device may be chemically cleaned or sterilized to a medical standard. 
         [0172]    Typically, within the outer silicone or elastomeric casing is a shell that houses internally, in the embodiments presented, vibratory motors, battery, control circuit, pressure sensor, sensors, and charging port. Within embodiments of the invention other functional elements may be employed for generating physical stimulus, providing user interface, wireless transceiver for communicating to an associated electronic device (PED or FED) or other ADDEV, etc. Within the description of embodiments of the invention and associated figures such elements are not presented for clarity of description, figures etc. However, as described at the end of the specification such elements may or may not be implemented within embodiments of the invention. Accordingly, the shell may comprise a single chamber or a plurality of chambers and may be formed from one piece part or multiple piece parts which are connected via the casing and/or discrete or connected by a central portion with different degrees of rigidity range from solid to a living hinge. 
         [0173]    Optionally, the ADDEV may employ one, two, three or more motors as well as actuators of one, two or more different technical approaches. For example one or more vibratory motors may provide high end vibrations whilst one or more vibratory or high impact gear-reduced motors may provide a low frequency “rumble” from larger weighted motors or through controlled frequency offset “throbbing.” Optionally, linear vibratory motors may be disposed within the regions on the outer surface of the recipient&#39;s body or the inserted portion(s) whilst generally rotating asymmetric weight motors are within the shell of the inserted portion(s). Optionally, the outer surface of the ADDEV may provide electrical stimulation contacts through metal contacts or conductive silicone pads for example at predetermined locations on the inserted portion as well as the discussion supra in respect the clitoral region. Equally, contacts may be disposed on the lower outer portion of the ADDEV to engage the recipient&#39;s lower labial lips, etc. 
         [0174]    Embodiments of the invention with respect to controlling an ADDEV such as described within the embodiments of the invention supra in respect of  FIGS. 1 to 17  may employ one or more methodologies as known within the art. Such control may be provided, for example, through a remote control wirelessly connected to the ADDEV, a PED or FED wirelessly connected to the ADDEV, a remote control wired to the ADDEV, and a control interface on the ADDEV allowing selection of predetermined program. In instances of wireless interfaced controllers the control may be local, i.e. by a user engaged in a sexual activity involving the ADDEV, or the control may be remote. 
         [0175]    Embodiments of the invention with respect to powering an ADDEV such as described within the embodiments of the invention supra in respect of  FIGS. 1 to 17  may employ one or more methodologies as known within the art. For example, the ADDEV may comprise a rechargeable battery or batteries within the shell which may be of a standard form/type, such as AA, AAA, etc. or custom to the ADDEV and/or another product. Alternatively, the ADDEV may employ non-rechargeable batteries and require an access to allow in insertion/removal of the battery or batteries or the ADDEV may be disposed of once the batteries have been exhausted. Optionally, the ADDEV may be powered directly from electrical mains supply through a transformer to support extended use or high power requirements not supportable by realistic battery configurations. Where an electrical connection is made to the ADDEV this may be similarly via a technique known in the prior art such as plug-socket connection, magnetic electrical connectors, etc. 
         [0176]    Whilst the ADDEV has been primarily described with respect to an ADDEV for use in providing stimulation to a female user vaginally whilst a user orally stimulated their clitoris and/or clitoral region it would be evident that embodiments of the invention may also be employed providing stimulation of the external vaginal area, labia, perineum etc. as well as male perineum, testes, etc. 
         [0177]    Embodiments of the invention with respect to the ADDEV such as described within the embodiments of the invention supra in respect of  FIGS. 1 to 17  may employ a “sticky” surface for the outer surface engaging a recipient&#39;s body (e.g. being formed from a low durometer silicone for example) so that the surface is designed to “stick” to skin so it stays in place. This “sticky” surface may be mirror surface, matt or textured for grip. Examples of materials may be those with durometer ideal Shore A10 or lower, Shore A5 or lower, or Shore A1. In some embodiments of the invention a region or regions of the casing may be formed from a gel such as the Ecoflex™ platinum catalyzed silicones for example certified to ISI 10993-10 for skin irritation/sensitization and having, for example, Shore 00-50 hardness (below the Shore A scale), Shore 00-30 hardness, Shore 00-20 hardness, or Shore 00-10 hardness. Within embodiments of the invention the footprint of the casing may be significantly larger than the shell (mechanical assembly) footprint, larger than the shell print, approximately the same as the shell footprint, and smaller than the shell footprint. Where the shell footprint is larger than the shell footprint its mechanical structure may be such that it does not droop under its weight/gravity when held free, droops a small amount, droops a moderate amount, or droops completely according to the desired characteristics. In embodiments of the invention the casing around the shell may act like a thin sheet (&lt;&lt;1 mm thick), like a fabric or material, like a sheet (˜1 mm), a thick sheet (&gt;1 mm). Optionally, the lower surface of the casing designed for placement against a user&#39;s groin/stomach may be sticky and when washed recover this stickiness in its entirety or in different regions or areas. 
         [0178]    Optionally, the outer surface which may contact the user providing oral stimulation may be smooth with low friction to human skin, smooth with minimal friction to human skin, smooth with moderate friction to human skin, smooth with high friction to human skin in its entirety or in different regions or areas. Alternatively, the surface may be smooth, textured, and/or rough and have low friction, negligible friction, moderate friction, and/or high friction in its entirety or in different regions or areas. Optionally, the surface may be textured with low friction to human skin, textured with minimal friction to human skin, textured with moderate friction to human skin, or textured with high friction to human skin in its entirety or in different regions. Optionally, the surface of the casing in its entirety or in different regions or areas may be used in conjunction with disposable sheets that provide adhesion and/or friction in predetermined levels. 
         [0179]    Within embodiments of the invention the casing, for example formed from silicone, is the only material surrounding the casing and the surface profile is derived from applying the casing to the contoured surface of the shell. In other embodiments of the invention the surface profile is derived from multiple applications of a single material forming the casing. In other embodiments of the invention an additional material or materials are disposed between the shell and the casing. This, may for example, be a preform formed from the same material as the casing such that the casing is applied as a single or multiple dip coating for example, a preform formed from another silicone of different characteristics to the casing, a preform formed from a plastic, a preform formed from a low density foam, from a medium density foam, or a high density foam. Alternatively, a combination of materials may be employed such as two or more plastics, two or more foams, a foam and a plastic, a foam and a silicone, a form and metal. The materials may be layered, inserted, embedded, etc. without departing from the scope of the invention. However, a characteristic of these materials is the transmission of vibratory motion arising from the active elements within the ADDEV according to embodiments of the invention. Within passive embodiments this characteristic of material selection is removed. 
         [0180]    Within the embodiments of the invention with active elements these are mounted to predetermined portions of the shell which is surrounded by the casing. Other embodiments may exploit a passive inserted portion mimicking a dildo function rather than a vibrator. As noted above the ADDEV according to embodiments of the invention may, in addition, to a silicone outer comprise one or more materials to provide mechanical structures such as ridges, shell, scaffold, etc. whilst the casing is smooth.
