   BACKGROUND OF THE INVENTION 
   Traditionally, eyeglasses have not contained or made any use of electrical components. In recent years, attempts to include electrical components within eyeglasses have had limited success. Even incorporating a small electrical component, such as a microphone, into an eyeglass frame may not be a simple task because, for example, of the necessary electrical connections with the electrical component. Clearly, larger scale electrical components would be more difficult to be provided in or attached to eyeglass frames. Many eyeglasses frames tend to be very compact and lightweight and thus may not have a lot of space for electrical components. Moreover, since eyeglass frames are often fashionable items whose designs are important, there are substantial design tradeoffs involved with providing or attaching electrical components to eyeglass frames. 
   Even if electrical components are provided in an eyeglass frame, the ability to alter or change electrical components is problematic. Conventionally, once an eyeglass frame is manufactured, electrical components embedded in the eyeglass frame may not be removed, nor can addition electrical components be added into the eyeglass frame. Attachment of electrical components to eyeglass frames has not proven to be reliable, design friendly or commercially successful. 
   Hence, there is a need for improved approaches to facilitate modifications or alterations to electrical components used with eyeglasses. 
   SUMMARY OF THE INVENTION 
   Generally speaking, the invention pertains to techniques for providing eyewear with electrical components. The electrical components can provide electrical technology to eyewear (e.g., eyeglasses) without having to substantially compromise aesthetic design principles of the eyewear. Often, the electrical components can be attached to the eyewear as an after-market enhancement. The electrical components can operate independently or together with other electrical components provided elsewhere. 
   One aspect of the invention relates to temple arrangements for use with eyeglasses. According to this aspect, a temple arrangement includes one or more electrical components. The one or more electrical components are attached to or at least partially embedded in the temple arrangement. 
   Another aspect of the invention relates to a temple adapter for use with eyeglasses. According to this aspect, a temple adapter includes one or more electrical components that are able to be mechanically (and optionally electrically) coupled to a temple (including a temple tip) of the eyeglasses. 
   Still another aspect of the invention relates to one or more swappable temple portions for a pair of glasses. In one embodiment, a temple has a forward portion and a rearward portion which can removably couple to one another. In one implementation, different rearward portions can be used with the same forward portion. In other words, the different rearward portions can be swapped with one another. In one implementation, the different rearward portions can offer different electrical components/functionalities to the pair of glasses. For example, the different rearward portions can provide different electrical components/functionalities such as: battery/power, wireless communication, radio, headset, GPS, pedometer, sun sensor, hearing enhancement, image/video capturing, etc. In another embodiment, different forward portions can be used with the same rearward portion. 
   Yet still another aspect of the invention relates to eyewear having an extended endpiece so as to facilitate placement of one or more electrical components at the extended endpiece. The one or more electrical components can operate independently or together with other electrical components provided elsewhere. For example, other electrical components can be provided in other regions of the frame for the eyewear. In one particular example, the other electrical components can be located in a bridge area of the frame for the eyewear. In such an example, given that the endpiece is extended, the one or more electrical components can be placed at the endpiece and thereby communicate with other electrical components in a front area or the other endpiece without having to communicate through a hinge or connector. 
   The electrical components can support signal capturing, signal processing, signal transmission, signal display, signal storage and/or power provision. The signals can be, for example, analog or digital signals. The electrical components can, for example, be used to provide audio output and/or audio pick-up. The electrical components may include and/or control one or more sensors to monitor and/or signal the conditions of a user of the eyewear. The electrical components may also include and/or control one or more operation indicators to signal operational status of at least some other electrical components. In addition, the electrical components can be or pertain to a circuit board or module, which includes a plurality of electrical components. 
   The invention can be implemented in numerous ways, including a method, system, device, apparatus, and a computer readable medium. Several embodiments of the invention are discussed below. 
   Other aspects and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.

   DETAILED DESCRIPTION OF THE INVENTION 
   The invention pertains to techniques for providing eyewear with electrical components. The electrical components can provide electrical technology to eyewear (e.g., eyeglasses) without having to substantially compromise aesthetic design principles of the eyewear. Often, the electrical components can be attached to the eyewear as an after-market enhancement. The electrical components can operate independently or together with other electrical components provided elsewhere. 
   One aspect of the invention relates to temple arrangements for use with eyeglasses. According to this aspect, a temple arrangement includes one or more electrical components. The one or more electrical components are attached to or at least partially embedded in the temple arrangement. 
   Another aspect of the invention relates to a temple adapter for use with eyeglasses. According to this aspect, a temple adapter includes one or more electrical components that are able to be mechanically (and optionally electrically) coupled to a temple (including a temple tip) of the eyeglasses. 
   Still another aspect of the invention relates to one or more swappable temple portions for a pair of glasses. In one aspect, a temple has a forward portion and a rearward portion which can removably couple to one another. In one embodiment, different rearward portions can be used with the same forward portion. In other words, the different rearward portions can be swapped with one another. In one implementation, the different rearward portions can offer different electrical components/functionalities to the pair of glasses. For example, the different rearward portions can provide different electrical components/functionalities such as: battery/power, wireless communication, radio, headset, GPS, pedometer, sun sensor, hearing enhancement, image/video capturing, etc. In another embodiment, different forward portions can be used with the same rearward portion. 
   The electrical components can support signal capturing, signal processing, signal transmission, signal display, signal storage and/or power provision. The signals can be, for example, analog or digital signals. The electrical components can, for example, be used to provide audio output and/or audio pick-up. The electrical components may include and/or control one or more sensors to monitor and/or signal the conditions of a user of the eyewear. The electrical components may also include and/or control one or more operation indicators to signal operational status of at least some other electrical components. In addition, the electrical components can be or pertain to a circuit board or module, which includes a plurality of electrical components. 
   Embodiments of different aspects of the invention are discussed below with reference to  FIGS. 1-10C . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. 
     FIG. 1  is a perspective view of a pair of glasses  100  according to one embodiment of the invention. The glasses  100  include a frame and a pair of lenses  102 . The frame has lens holders  104  that hold the lenses  102  in position. The frame also has a bridge  106 . The glasses  100  further include a pair of temples (or arms)  108 . The temples  108  are considered part of the frame. As shown in  FIG. 1 , each of the temples  108  is coupled to one of the lens holders  104  by a hinge  109 . In one embodiment, the temples  108  can be removed from the frame (e.g., at the hinge  109 ). 
   In addition, temple arrangements  110  are attached to the temples  108 . Here, one or both of the temples  108  can include a temple arrangement  110 . A temple arrangement  110  can include one or more electrical components  112 . In one embodiment, the temple arrangements  110  can be considered separate parts that can be attached to respective temples  108 . Once attached, the temple arrangements  110  can be considered part of, or an extension to, the temples  108 . 
   By having one or more electrical components  112  in one or more of the temple arrangements  110 , electrical capabilities can be provided to the glasses  100  without burdensome impact to the design of other parts of the frames. Moreover, by providing electrical components in one or more of the temple arrangements  112 , electrical capabilities can be added to eyeglasses in an after-market manner. Still further, by replacing temple arrangements, a user could alter the electrical capabilities of his eyeglasses. 
   In one embodiment, the glasses  100  do not have any other embedded electrical components, such as within the frame, except those in one or both of the temple arrangements  112 . In another embodiment, the glasses  100  include one or more other electrical components embedded or attached to the frame of the glasses  100  and the components are electrically coupled to the one or more electrical components  112  in one or both of the temple arrangements  110 . 
   In different embodiments, the glasses  100  can be, for example, a pair of sunglasses, fit-over glasses, prescription glasses, reading glasses, or safety glasses. 
     FIG. 2  illustrates a diagram of a number of different embodiments of temple arrangements  200  according to the invention. A temple arrangement  200  can be a temple tip, a temple fit-over, or a temple cover. In one embodiment, a temple tip is a structure that attaches to a rearward portion of a temple. In one embodiment, a temple tip can pertain to an enclosure that grabs onto a rearward portion of a temple. A temple tip is particularly common for wire frame eyeglass where the temple tip attaches to the rearward end of the temple and provides a surface suitable for positioning proximate to the user&#39;s ear. For example,  FIG. 1  illustrates the temple arrangement  112  implemented as a temple tip. 
   In one embodiment, a temple tip is removable from its corresponding temple so that it can be replaced. The temple tip can be originally provided with the purchase of a pair of eyeglasses. Alternatively, the temple tip can be a replacement part that can be purchased separately and subsequently mounted onto a rearward portion of a temple of a pair of eyeglasses after removing any original temple tip. In another embodiment, a temple tip is permanently held onto the corresponding temple, for example, by an adhesive (e.g., epoxy, glue, etc.). 
   In one embodiment, a temple fit-over fits over at least a portion of the rearward end of a temple. If the rearward end of the temple has a temple tip, at least a portion of the temple tip can be fitted over by the temple fit-over. In one embodiment, a temple cover slides over and at least partially covers a portion of the rearward end of a temple. If the rearward end of the temple has a temple tip, at least a portion of the temple tip can be covered by the temple cover. 
   A temple cover is typically made of a material that is more flexible than a temple fit-over. For example, a temple cover can be made of a fabric or other materials, such as a sock or sleeve; while a temple fit-over can be made of plastic. 
   A temple arrangement  200  can be made of the same or different materials than the temple or other parts of the frame of the pair of eyeglasses. To illustrate, a pair of glasses with a metal frame can have non-metallic temple tips. A temple arrangement  200  can be of a color that is the same as, or similar to, or different from, that of the temple. 
   A temple arrangement  200  can be held onto a temple by frictional force. For example, if the temple arrangement  200  is a temple fit-over, it can be held onto an existing temple or temple tip by frictional force. Here, the temple fit-over is often removable. In another embodiment, the temple arrangement  200  can be permanently held onto its corresponding temple or temple tip. For example, the temple arrangement can be permanently held onto the corresponding temple or temple tip, for example, by an adhesive (e.g., epoxy, glue, etc.). 
   Depending on applications, a temple arrangement can be of different shapes. The shape can depend on the type of glasses. For example, a temple arrangement for fit-over glasses can be bigger than a temple arrangement for prescription glasses. The shape of the temple arrangement can also depend on applications for the electronic component(s) that are fully or partially embedded in the temple arrangement. Of course, aesthetic reasons can also influence shape (e.g., design, size, style) of a temple arrangement. 
   In one embodiment, the temple arrangement is a structure that has at least one electrical component attached thereto or at least partially embedded therein. In another embodiment, all of the electrical components to be provided with the temple arrangement are at least partially embedded in the temple arrangement. 
     FIG. 3A  is a diagram of a portion  300  of a pair of eyeglasses according to one embodiment of the invention. The portion  300  includes a temple  302  that is associated with a pair of eyeglasses. Over the end of the temple  302  that is opposite the associated lens holder, a temple tip  304  is provided. The temple tip  304  can, for example, be held to the temple  302  by frictional forces and/or adhesive. The temple tip  304  includes at least one electrical component  306  that is at least partially embedded therein. A wide range of functionalities can be provided by the at least one electrical component  306 . The temple tip  304  can be considered separate from or part of the temple  302 . For example, when the temple tip  304  is not attached to the temple  302 , the temple tip  304  is considered a separate part. As another example, when the temple tip  304  is attached to the temple  302 , the temple tip  304  can be considered separate from or part of the temple  302 . 
   The temple tip  304  can be manufactured and delivered to resellers or retailers and thereafter sold attached to eyeglasses. Alternatively, the temple tip  304  can be separately provided as an optional replacement temple tip for an original temple tip. Hence, after or during purchasing a pair of eyeglasses, upgrade of the eyeglasses can be had by replacing an existing temple tip with a replacement temple tip. The colors and shapes of the temple tip  304  can vary widely. In the after manufacturing environment, the reseller or retailer can be provided with a range of different colors and shapes so that a user can receive a replacement temple tip that reasonably matches the color and shape of the temple or that provides an altered appearance as desired by the user. 
   A number of embodiments have been described regarding one or more electrical components at least partially embedded in a pair of glasses. In one embodiment, one or more electrical components are at least partially embedded in a temple tip of a pair of glasses. Temple tips are relatively common for wire or metal frames which have wire or metal temples. The pair of glasses has a first and a second lens holders for receiving lenses. Each of the lens holders has a first side and a second side. The pair of glasses has a bridge element that couples the first side of the first lens holder to the second side of the second lens holder. The pair of glasses also includes a first temple and a second temple. The first temple is pivotally secured to the second side of the first lens holder through a joint, while the second temple is pivotally secured to the first side of the second lens holder through another joint. A temple typically has two ends, a first end and a second end. The first end can be the end that is pivotally secured to a lens holder through a joint, and the second end can be the other end of the temple. It is not uncommon that a temple includes a main body and an enclosure that grabs onto the main body of the temple. The second end is typically where the enclosure grabs onto the main body. The enclosure can be made of a different material than the main body of the temple. In one embodiment, such an enclosure is a temple tip, and there is an electrical component, partially or fully, embedded in the temple tip. There can also be a connector at the temple tip. In another embodiment, the temple tip can include a female connector. In still another embodiment, as a temple tip grabs onto the main body of the temple, a connector at the temple tip (such as a female connector) can make electrical contact with another connector (such as a male connector) at the main body of the temple. Typically, particularly before a pair of glasses has been extensively worn, the temple tip can be removed and re-inserted back on to the main body of the temple without much difficulty. Such a temple tip can be an after-market component, with different temple tips having different electrical components to serve different functions. 
   Besides a temple tip such as illustrated in  FIG. 3A , a temple tip can also be effectively modified by a fit-over temple or temple cover. 
     FIG. 3B  is a diagram of a temple cover  320  that at least partially covers a temple (e.g., temple and/or temple tip) according to one embodiment of the invention. As an example, the temple cover  320  can be made of a fabric or other material, such as a sock or sleeve, that slides over and at least partially covers a temple or a temple tip. The temple cover  320  can include at least one electrical component  322  that is either attached thereto or at least partially embedded therein. The temple cover  320  can also include an opening  324  so as to receive a temple or a temple tip. In one embodiment, the temple cover  320  is placed over a substantial portion of a temple tip, and the opening  324  can extend to a far end  326  so as to receive all or a substantial part of the temple tip. The temple cover  320  can, for example, be held to a temple or a temple tip by frictional forces and/or adhesive. 
     FIG. 3C  is a diagram of a fit-over temple  340  that at least partially fits over a temple (e.g., temple and/or temple tip) according to one embodiment of the invention. For example, the fit-over temple  340  can at least partially fit-over a temple tip. The fit-over temple  340  includes at least one electrical component  342  that is either attached thereto or at least partially embedded therein. The fit-over temple  340  can also include an opening  344  so as to receive a temple or a temple tip. The depth and/or width of the opening  344  within the fit-over temple  340  can vary depending on the extent to which it is being fit over a temple or a temple tip. The fit-over temple  340  can, for example, be held to a temple or temple tip by frictional forces and/or adhesive. As an example, the fit-over temple  340  can be plastic or other material. The colors and shapes of the fit-over temple  340  can have a lot of variations. 
   A wide range of functionalities can be provided by the at least one electrical component (e.g., electrical component  322  and  342 ). In the after manufacturing environment, the reseller or retailer can be provided with a range of different colors and shapes so that a user can receive a replacement temple cover or fit-over temple that reasonably matches the color and shape of the temple or that provides an altered appearance as desired by the user. 
     FIG. 3D and 3E  are diagrams of a temple arrangement  360  according to another embodiment of the invention.  FIG. 3D  is a side view of the temple arrangement  360 , and  FIG. 3E  is a front view of the temple arrangement  360 . In this embodiment, the temple arrangement  360  is a temple tip that can be attached to a temple (e.g., temple body) of a pair of eyeglasses. The temple arrangement  360  includes a speaker housing  362  allowing a speaker  364  to be at least partially embedded within the temple arrangement  360 . An audio sound output by the speaker  364  is coupled to an ear plug  366  by way of the speaker housing  362  and a tube  368 . Typically, the tube  368  is a flexible tube, such as a flexible plastic tube. A user of the eyeglasses having the temple arrangement  360  can place the ear plug  366  within her ear to facilitate coupling of the audio sound from the speaker  364  to the ear. The tube  368  can have a disconnection region  370  whereby at least a section of the tube  368  and the attached ear plug  366  can be removed from the temple arrangement  360 , such as when audio output is not being listened to. The tube  368  and/or the speaker housing  362  can also be capable of rotating with respect to the temple arrangement  360  to facilitate ease of use. Still further, the temple arrangement  360  can include a connector  372 , such as a male audio connector (e.g., 2.5 mm, stereo mini-phone connector). The connector  372  provides a means to electrically connect an external audio source to the speaker  364  within the temple arrangement  360 . For example, at least one wire (not shown) that is internal to the temple arrangement  360  can be used to electrically connect the speaker  364  to the connector  372 . 
   In one embodiment, an electrical component is a component of an electrical circuit or system, and the electrical circuit or system is for performing at least a desired, intended or predetermined function. 
   In one embodiment, a temple tip, fit-over temple or temple cover according to the invention can further include a connector or cable to facilitate electrical connection with the at least one electrical component that is either attached to a temple or a temple tip or at least partially embedded therein. 
   Still another aspect of the invention relates to one or more swappable temple portions for a pair of glasses. According to this aspect, a temple has a forward portion and a rearward portion which can removably couple to one another. In one embodiment, different rearward portions can be used with the same forward portion. In other words, the different rearward portions can be swapped with one another. In one implementation, the different rearward portions can offer different electrical components/functionalities to the pair of glasses. For example, the different rearward portions can provide different electrical components/functionalities such as: battery/power, wireless communication, radio, headset, GPS, pedometer, sun sensor, hearing enhancement, image/video capturing, etc. In another embodiment, different forward portions can be used with the same rearward portion. 
   In one embodiment, only one of the temples of an eyeglass frame has swappable part(s). In another embodiment, both of the temples of an eyeglass frame have swappable part(s). Regardless, viewed in one way, each of the swappable parts at a temple can be viewed as a removable peripheral device to the eyeglass frame. 
   In one embodiment, a temple is a multi-part temple. The multi-part temple includes at least a forward (or first) part and a rearward (or second) part. The forward part is typically integral with or coupled to an eyeglass frame (such as at the lens holder or hinge region of an eyeglass frame). The rearward part removably connects with the forward part. The removable connection allows the rearward part to be removed for any of a variety of reasons. For example, the rearward part can be removed to: (1) connect a different rearward part; (2) connect to a peripheral bus (e.g., for data download); or (3) charge a battery (e.g., located in forward or rearward part). 
   The removable connection between the forward and rearward parts of the multi-part temple physically attaches and secures the rearward part to the forward part by way of at least a mechanical connection. The mechanical connection can be provided in a variety of ways, such as through use of one or more connectors, snaps, detents, bayonets, etc. 
   In addition, the removable connection between the forward and the rearward parts of the multi-part temple can provide (or facilitate) an electrical connection between the forward and rearward parts. In one embodiment, the forward part of the temple (or some other part of the eyeglass frame) includes one or more electrical components, and the rearward part includes one or more electrical components. In such case, the electrical connection serves to electrically connect one or more of the electrical components of the forward part (or other part of the eyeglass frame) with one or more of the electrical components of the rearward part. For example, the forward part of the temple can include one or more electronic components (e.g., integrated circuit) that are electrically connected to one or more electronic components in the rearward part. 
   However, in the event that all needed electrical components are within the rearward part of the multi-part temple, electrical connection between the forward part and the rearward part may not be needed. Accordingly, in some embodiments, no electrical components will be needed in the forward part; instead, all the needed electrical components will be provided in the rearward part. 
   Various embodiments of eyewear can utilize the multi-part temples to provided electrical components to eyeglass frames in a convenient and user friendly manner. As one example, consider an eyeglass frame that supports a camera. The electrical components can include an image sensor, a memory, a microcontroller, and a battery. One or more of these electrical components can be in the forward part (or other part of the eyeglass frame) and the remaining one or more electrical components can be in the rearward part. For example, the image sensor and the microcontroller can be in the forward part and the battery and the memory can be in the rearward part. Additionally, if the camera makes use of a display (e.g., LCD), the display could be in either the forward part or the rearward part. The eyeglass frame might also include other electrical components for additional functionality. Examples of additional functionality include: global positioning system, antenna, user interface (e.g., buttons, switches, etc), display, microphone, earphone, etc. In another example, all of the electrical components supporting the camera functionality can be provided in the rearward part of the multi-part temple. 
   In one embodiment, the electrical components provided in the forward part are able to be shared with different rearward parts. In other words, different rearward parts can be swapped. For example, a different rearward part can be connected to the forward part to provide the eyeglass frame with different functionality. Examples of some of the different functionality that can be provided in this matter include: radio receiver (e.g., satellite radio), media player, pedometer, wireless communication, sun monitor, hearing enhancement, global positioning, etc. In a first example, in the case of a radio receiver, the forward part can include a display, while the rearward part can include a tuner, a rechargeable battery, an amplifier, and earphones or earphone connectors. In a second example, in the case of a media player, the forward part can include a display, while the rearward part can include a media player module, a memory, a rechargeable battery, a switch and earphones or earphone connectors. In a third example, in the case of a pedometer, the forward part can include a display, while the rearward part can include an accelerometer, a rechargeable battery, a memory and a microcontroller. In a fourth example, in the case of a wireless communication device, the forward part can include a display, while the rearward part can include a battery, an antenna, a wireless module, earphones or earphone connectors, and a user interface. The user interface, for example, can include buttons, which, for example, can facilitate user input with respect to on/off, volume, and accept or decline call. In this case, information displayed can include battery status, device status, caller ID, etc. In these four examples, the forward part includes a display and thus the forward part can be used (i.e., shared) with any of the different rearward parts to thereby provide different functionality to the eyeglass frames. Hence, by swapping one of these different rearward parts, the same pair of eyeglasses can provide different functionality. 
   A multi-part temple can be manufactured and delivered to resellers or retailers and thereafter sold attached to eyeglasses. Alternatively, a rearward part can be separately provided as a separate part or as an optional rearward part that can be swapped with an original rearward part. Hence, after or during purchasing a pair of eyeglasses, alteration, upgrade or conversion of the eyeglasses can be had by swapping in another rearward part. The electrical components or functions supported by the rearward part can vary widely. The colors and shapes of the rearward parts also can vary widely. For example, in the retailing or after manufacturing environment, the reseller or retailer can be provided with a range of different colors and shapes so that a user can receive a rearward part that reasonably matches the color and shape of the multi-part temple or that provides an altered appearance as desired by the user. 
     FIG. 3F  is a diagram of a multi-part temple  1300  according to one embodiment of the invention. The multi-part temple  1300  has a forward part  1302  and a rearward part  1304 . The rearward part  1304  is removably connected to the forward part  1302  such that the rearward part  1304  is removable. Once removed, the same rearward part or a different rearward part can be later connected to the forward part  1302 . Alternatively, a cable can be connected to the forward part  1302  when the rearward part  1304  is removed. The cable can facilitate data transfer, battery charging, etc, depending on the electrical components in the forward part  1302 . 
     FIG. 3G  is a diagram of a multi-part temple  1310  according to one embodiment of the invention. The multi-part temple  1310  can represent the multi-part temple  1300  shown in  FIG. 1  in one embodiment. In  FIG. 3G , a forward part  1312  and a rearward part  1314  are shown disconnected. The forward part  1312  has a mechanical element  1316  and the rearward part  1314  has a corresponding opening  1318 . Once connected together, the mechanical element  1316  of the forward part  1312  is inserted into the opening  1318 , thereby mechanically coupling the rearward part  1314  to the forward part  1312 . Once mechanically coupled the rearward part  1314  is secured to the forward part  1312 , but remains removable. 
     FIG. 3H  is a diagram of a multi-part temple  1320  according to one embodiment of the invention. The multi-part temple  1320  can represent the multi-part temple  1300  shown in  FIG. 1  in one embodiment. In  FIG. 3H , a forward part  1322  and a rearward part  1324  are shown disconnected. The forward part  1322  has a connector  1326  and the rearward part  1324  has a corresponding connector  1328  embedded therein. Once connected together, the connector  1326  of the forward part  1322  is inserted into the corresponding connector  1328 , thereby mechanically coupling the rearward part  1324  to the forward part  1322 . Once mechanically coupled the rearward part  1324  is secured to the forward part  1322 , but remains removable. Additionally, the connection of the connector  1326  and the corresponding connector  1328  can also provide an electrical connection. An electrical connection would serve to enable electrical components in the forward part  1322  (or other parts of an eyeglass frame) to electrically connect to electrical components in the rearward part  1324 . For example, the electrical connection can provide electrical connections for one or more electrical wires. An example of one suitable type of connector is a USB connector which can provide mechanical and electrical connection. 
   As noted above, a rearward part of a multi-part temple can include one or more electrical components.  FIG. 31  is a diagram of a rearward part  1330  of a multi-part temple according to one embodiment of the invention. The rearward part  1330  has a body  1332  with electrical circuitry  1334  internal to the body  1332 . As one example, the electrical circuitry  1334  can pertain to data storage (e.g., memory). In such an example, the rearward part  1330  can be considered a memory stick or a memory card. As other examples, the electrical circuitry  1334  can pertain to a battery/power source, a sun sensor, a pedometer, a media player, a wireless module, etc. 
     FIG. 3J  is a diagram of a rearward part  1340  of a multi-part temple according to another embodiment of the invention. The rearward part  1340  has a body  1342  with an ear bud  1344  and an ear bud arm  1346  extending therefrom. In addition, the body  1342  includes at least one conductor  1347  and electrical circuitry  1348  internal to the body  1342 . The at least one conductor  1347  can electrically connect the electrical circuitry  1348  with the ear bud  1344 , where the at least one conductor  1347  extends through the ear bud arm  1346  to the ear bud  1344 . Optionally, the body  1342  can further include an antenna  1349  internal to the body  1342 . In the case where the electrical circuitry  1348  includes a wireless receiver (e.g., Bluetooth, XM, FM), the antenna  1349  can enhance reception. As an example, the electrical circuitry  1348 , can be a wireless module for wireless communications or a receiver for XM or FM signals. Additionally or alternatively, the electrical circuitry  1348  can, for example, pertain to one or more of a data storage device, battery/power source, a sun sensor, a pedometer, a media player, etc. 
     FIG. 3K  is a diagram of a rearward part  1350  of a multi-part temple according to another embodiment of the invention. The rearward part  1330  has a body  1352  with a printed circuit board  1354  internal to the body  1352 . A display device  1356  (e.g., LCD) can be provided on the body  1352 . In one example, the display device  1356  can be mounted to the circuit board  1354  and exposed through an opening in the body  1352  so as to be visible by a user of the eyeglasses using the multi-part temple. Optionally, at least a portion of the printed circuit board  1354  can conform to the shape of the body  1352 . The ability to conform, even partially, allows the printed circuit board  1354  to yield greater surface area within a temple, which tends to be small and stylized. The integrated circuit board  1354  can have one or more electronic components (e.g., integrated circuits) mounted thereon. 
     FIGS. 3L-3O  are diagrams of representative forward parts for multi-part temples according to different embodiments of the invention.  FIG. 3L  is a diagram of an exemplary forward part  1360  having a mechanical element  1362  that includes one or more detents  1364 . When a rearward part is connected to the forward part  1360 , the mechanical element  1362  is inserted into an opening (e.g., opening  1318 ) and held securely in place by mechanical forces facilitated by the mechanical element  1362  and the detents  1364 . This can be accomplished through different methods, such as with corresponding protruding portions in the opening that can, for example, be aligned with the detents  1364 . For example, the protruding portions can snap into place or biased by springs (e.g., spring-loaded). 
     FIG. 3M  is a diagram of an exemplary forward part  1370  having a mechanical element  1372  that includes one or more protrusions  1374 . When a rearward part is connected to the forward part  1370 , the mechanical element  1372  is inserted into an opening (e.g., opening  1318 ) and held securely in place by mechanical forces facilitated by the mechanical element  1372  and the protrusions  1374 . In one embodiment, the protrusions  1374  are spring-loaded to facilitate connection with the opening. 
     FIG. 3N  is a diagram of an exemplary forward part  1380  having a mechanical element  1382  that includes one or more bayonet structures  1384 . To connect a rearward part to the forward part  1380 , the mechanical element  1382  is inserted into an opening (e.g., opening  1318 ) that has groves (in the direction substantially parallel to the axis of the mechanical element  1382 ) for receiving the bayonet structures  1384 . The rearward part can be connected with the forward part  1380  when the groves within the opening of the rearward part are aligned with the bayonet structures  1384 . Once the mechanical element  1382  is so inserted, the rearward part can be rotated with respect to the forward part  1380 . The rotation causes the bayonet structures  1384  to no longer be aligned with the grooves. As a result, the rearward part is mechanically secured to the forward part  1380  (and thus the eyeglass frame) in a bayonet like manner. 
   In one embodiment, a connector is used to removably couple the rearward portion to the forward portion of a multi-part temple. For example, the connector can be standard connector. One example of a suitable connector is a Universal Serial Bus (USB) connector. 
     FIG. 3O  is a diagram of an exemplary forward part  1390  having an electrical connector  1392 . The connector  1392  facilitates mechanical and/or electrical connections between the forward part  1390  and a rearward part. When a rearward part is connected to the forward part  1390 , the connector  1392  is inserted into an opening (e.g., opening  1328 ) and held securely in place by mechanical forces. There can be additional mechanical connecting mechanisms to further secure the connection. 
   In one embodiment, the opening receiving the connector  1392  can include a corresponding (i.e., counterpart) connector. When the connector  1392  is connected with the corresponding connector within the opening, the rearward part is physically secured to the forward part  1390 . For example, mechanical forces can hold the connector  1392  and the corresponding connector in a connected position. In addition, when the connector  1392  and the corresponding counterpart connector are coupled together, one or more electrical connections are facilitated. For example, each connector can be coupled to one or more electrical wires at the other connector so that wires from one part are able to be connected to corresponding wires on the other part. As a result, electrical component(s) in the rearward part are able to be electrically connected with electrical component(s) in the forward part  1390  (or elsewhere in the eyeglass frame). In one implementation, the connectors pertain to or resemble a Universal Serial Bus (USB) type connector. 
   In another embodiment, the opening receiving the connector  1392  does include a corresponding counterpart connector. In this embodiment, mechanical forces can hold the connector  1392  within the opening. Also, in this embodiment, electrical connections are not facilitated. 
   Although  FIGS. 3G-3N  pertain to connections having a male connector at the forward part and a female connector at the rearward part, it should be understood that alternatively the male connector can be at the rearward part and the female connector can be at the forward part. 
   Also, although  FIGS. 3G-3N  pertain to connections showing only one elongated portion (like a male connector) to be received by an opening (like a female connector), in other embodiments, there can be more than one elongated portion to be received by more than one opening. Also, the connections can be formed on the sides (i.e., outer surface), instead of by having elongated portions and openings positioned in the middle of (i.e., internal to) the forward and rearward parts. For example, there can be two prongs, one on the top surface and one on the bottom surface of a forward part. Each prong can be received by a counterpart detent in a rearward part, such as the prong on the top surface of the forward part to be received by a detent on the top surface of the rearward part. 
   In a number of embodiments, the forward part of the multi-part temple is substantially smaller than the rearward part. For example, in  FIG. 3F , the forward part  1302  is substantially smaller than the rearward part  1304 . In one embodiment, a forward part is large enough to house a connection mechanism used to couple with a rearward part and not too much larger. In another embodiment, a forward part and a rearward part are about the same size. In still another embodiment, a forward part is larger than a rearward part. 
   In one embodiment, neither the forward part nor the rearward part of a multi-part temple contains any electrical components. In such case, the rearward part can still be removable from the forward part. Such an embodiment enables a user to swap one (which can be substantially all of the temple) or both the rearward portions of both temples, with another rearward portion(s), such as for aesthetic, configuration or design reasons. 
   In one implementation, a connector is used to removably couple the rearward portion to the forward portion of the multi-part temple. For example, the connector can be a Universal Serial Bus (USB) connector. 
   In one embodiment, a forward part can be part of or integral with a corresponding region of a lens holder. In such case, there need not be any hinges for coupling the temples to the lens holders. 
   As noted above, connectors can be use to removably attach a temple to an eyeglass frame (e.g., lens holder) or to removably attach different portion(s) of a temple. These connectors can be provided for one or both temples of the eyeglass frames. With such temples being easily removable by users without the need for any special skill or tools, the temple parts can be interchangeable and can be separately sold or leased. 
   Further, to display various eyewear products, such as in a retail environment, an eyewear products display apparatus (e.g., stand) can include corresponding connectors or connector structures so that (i) separate temples (ii) separate parts of temples and/or (iii) eyeglass frames without temples can be connected to the eyewear products display apparatus for display. For example, if the eyewear products (e.g., frames, temples, etc.) use connectors, then the eyewear products display apparatus can support those same connectors (e.g., USB connectors) or compatible structures. This eyewear products display apparatus opens up new ways to organize and present eyewear products at retail stores. It also allows users to separately select a base eyewear frame and temples to be used therewith. The temples and the frames can be displayed detached from one another, such that a user can separately select and try different temples with frames. 
     FIG. 3P  is a diagram of an eyewear products display apparatus  1400  according to one embodiment of the invention. The apparatus  1400  has a first region  1404  of first type connectors (or compatible protrusions) integral with the apparatus  1400 . A plurality of eyeglass frames having second type connectors can be attached and displayed on the apparatus  1400  by connecting one or two of the second type connector of the eyeglass frames to those of the first type connectors of the first region of the apparatus  1400 . 
   The apparatus  1400  also can include a second region  1402  of second type connectors (or compatible openings) integral with the apparatus  1400 . A plurality of removable temples (and/or removable temple parts) having first type connectors can be attached and displayed on the apparatus  1400  by connecting the first type connectors of the removable temples (and/or removable temple parts) to those of the second type connectors (or compatible openings) in the second region  1402  of the apparatus  1400 . 
   In one embodiment, the first type connectors are male connectors and the second type connectors are corresponding female connectors which provide a secure mechanical connection. In one embodiment, the first type connectors and/or the second type connectors provided integral with the apparatus  1400  are not electrical connectors but compatible structures (e.g., protrusions and openings) such that a secure mechanical connect can be had. 
   In one embodiment, the orientation of at least some of the connectors in the apparatus  1400  is substantially horizontal. In other words, for example, when a rearward part of a temple is inserted into such a connector in the apparatus  1400 , the rearward part is substantially perpendicular to the surface of the apparatus  1400  as shown. In another embodiment, the orientation of at least some of the connectors in the apparatus  1400  is substantially facing upward or downward in a vertical manner. In other words, for example, when a rearward part of a temple is inserted into such a connector in the apparatus  1400 , the rearward part is substantially parallel to the surface of the apparatus  1400  as shown. In yet another embodiment, the orientation is at an acute angle relative to the surface of the apparatus  1400  as shown. In other words, for example, when a rearward part of a temple is inserted into a connector in the apparatus  1400 , the rearward part is at an acute angle relative to the surface of the apparatus  1440  as shown. The connectors in the apparatus  1400  can also be rotatable or movable, such as between different positions and/or angles. 
   Although  FIG. 3P  only depicts one side of the eyewear products display apparatus  1400 , the apparatus can have other like sides. For example, the apparatus  1400  can be a one, two, three or four sided apparatus. 
   In still another embodiment, at least one connector of the apparatus  1400  is connected to at least one electrical component in the apparatus  1400 . For example, when a selected temple part is connected to the connector, the at least one electrical component in the apparatus  1400  is electrically connected to an electrical component in the temple part, and together can perform an electrical operation. 
   In yet another embodiment, at least one connector of the apparatus  1400  is connected to another connector of the apparatus  1400 . This allows electrical connection between the different eyewear parts connected to the apparatus  1400 . For example, when a selected temple part is connected to the connector and a eyeglass frame is connected to the other connector, an electrical components within the eyeglass frame is electrically connected to an electrical component in the temple part, and together can perform an electrical operation. 
     FIG. 4  shows examples of different electrical components according to the present invention. Different embodiments of temple arrangements, temple adapters or temple parts according to the invention can use one or more of these different electrical components. 
   In one embodiment, the electrical component is an electrical connector. The connector can be a male connector or a female connector. Examples of different types of connectors have previously been described in the related patent applications, which have been incorporated by reference. 
   In one embodiment, the embedded electrical component is an electrical switch, such as one or more of those previously described in the related patent applications, which have been incorporated by reference. 
   In one embodiment, one electrical component can be a power source. The power source can be a battery, a solar cell or other type of power source. 
   In one embodiment, one electrical component can include a circuit board. The circuit board can be a rigid or a flexible circuit board. 
   In one embodiment, one electrical component can be an indicator. The indicator can be audio, visual, or physical (e.g., vibration). For example, the indicator can signal an event or condition to a user of the glasses. 
   In one embodiment, one electrical component can be a display, such as a LCD display. 
   In one embodiment, one electrical component can be a speaker. The speaker can provide an audio output for the benefit of the wearer of the glasses. The speaker can directly transmit sound to a user, such as a speaker mounted on an exterior surface of an eyeglass frame, or partially or fully embedded in an eyeglass frame, or a bone conducting type of speaker. Alternatively, the speaker can indirectly transmit sound to a user, such as through the use of a tube to deliver audio output proximate to a user&#39;s ear. 
   In one embodiment, one electrical component can be a controller. The controller can, for example, be a microprocessor. 
   In one embodiment, one electrical component can be a memory device. The memory device can be non-volatile memory, such as FLASH memory. The data stored in the memory device can be user data or data provided by other electrical components. 
   In one embodiment, one electrical component is a frequency receiver or a frequency transmitter. They can be in the radio frequency range. 
   In one embodiment, one electrical component can be a sensor. The sensor can be a temperature sensor. The temperature sensor can be used to sense the temperature of the wearer. In one embodiment, such a temperature sensor is in a temple tip. In measuring the temperature, the user can further press the temple tip towards his head to ensure better connection. One can also put the temple under one&#39;s tongue to measure body temperature. 
   In other different embodiments, one electrical component can be a motion detector, a speed sensor, a rate of ascent (or descent) detector, a pressure detector, or a detector for radiation, such as an ultraviolet (UV) detector. 
   In one embodiment, one electrical component is a radio frequency identification (RFID) tag. A RFID tag typically includes a memory chip and a radio antenna. The memory chip usually has a small storage capacity and thus does not include a large amount of information. A portion of such information can provide identifying information for the glasses. The memory chip may only have a few kilobytes, sufficient to encode information, such as a serial number, where and when the product (such as eyeglasses) was manufactured, and other relevant information. 
   The RFID tags can come in a number of configurations. For example, an active tag uses a battery-powered transponder to constantly emit signals which can carry information programmed into the memory chip. Active tags are more applicable to situations where readers are not close to the tags. A semi-passive tag likewise has a battery, but may not be activated until it receives a signal from a reader. They are more applicable to situations that do not need continuous connection and accessing. A passive tag has no battery; its antenna extracts power from a reader&#39;s radio wave signal to transmit the identifying information. Passive tags are typically relatively inexpensive, but may have to be within a few feet of a reader to extract power. The electrical component can be a passive RFID tag, or some other type of tag. 
   In one embodiment, one electrical component can be for locating the corresponding glasses. For example, the electrical component can produce a beeping tone when it receives a specific radio signal. A handheld device (such as a key chain accessory, can generate the specific radio signal (e.g., when a button is pushed). Through the beeping tone, one can locate the glasses. 
   As noted above, in one embodiment, the electrical component can be a sensor. More generally, a pair of glasses can include one or more sensors that can be used individually or in combination.  FIG. 5  is a chart  500  that depicts examples of sensors suitable for use in or attached to the glasses. 
   In one embodiment, the sensor is a “being worn” sensor. The “being worn” sensor indicates whether the glasses are being worn by its user. The “being worn” operation can be performed using, for example, a thermal sensor, a motion detector, a stress sensor or a switch. 
   In one embodiment, a motion detector is used as a “being worn” sensor. A threshold can be set, such that if the amount of motion exceeds the threshold, the glasses are assumed to be worn. The motion detector can, for example, be achieved by a mechanical mechanism or an accelerometer. 
   In another embodiment, the “being worn” sensor includes two thermal sensors. One sensor can be at approximately the middle of a temple, such as in a region that touches the head of the user wearing the glasses. The other sensor can be at one end of the temple, the end that is close to its hinge. If the temperature differential between the two sensors is beyond a certain preset value, the glasses would be assumed to be worn. The differential is presumed to be caused by a person wearing the pair of glasses. 
   In yet another embodiment, the “being worn” sensor includes a stress sensor at the hinge of the temple. The assumption is that when the eyewear is worn, the hinge is typically slightly stretched because typically, the width of the head of the user is slightly wider than the width between the temples when the two temples are in the extended positions. If the value of the stress sensor is beyond a certain preset value, the glasses would be assumed to be worn. 
   In a further embodiment, the “being worn” sensor can be a switch. For example, at the hinge between a temple and its corresponding lens holder, there is a switch. When that temple is in its extended position, i.e., fully extended outwards, the switch is turned on. The switch can be a pin-type switch. When the temple is fully extended outwards, the pin is pressed. When both temples are fully extended outwards, in one embodiment, the glasses would be assumed to be worn by the user. 
   In one embodiment, another type of sensor is an environmental sensor. The environmental sensor can sense environmental conditions, such as one or more of radiation (e.g., ultraviolet radiation or light), temperature (e.g., ambient temperature), pressure, humidity and toxins (e.g., chemicals, etc.). 
   In another embodiment, another type of sensor is a condition sensor. The condition sensor can sense the conditions of the user of the glasses. Examples of condition sensors include sensing one or more of distance traveled, location, speed, calories consumed, temperature and vital signs associated with the user of the glasses. The distance traveled could represent the horizontal distance traveled or the vertical distance (i.e., elevation) traveled. The speed can be the rate of movement along the horizontal distance traveled and/or the vertical distance. In yet another embodiment, the condition sensor can indirectly sense emotional conditions of the user of the glasses. 
   The sensors can be provided in a redundant or fault-tolerant manner. For example, sensors can come in pairs in the glasses. When one malfunctions, the other one will take over its operation. In another embodiment, the sensor information can be processed in a differential manner to examine changes to the sensor information. The differential can be based on time. The sensors can be powered by a battery, solar energy, or kinetic energy. For reduced power consumption, the sensors can remain in a low-power state unless data is being acquired by the sensors. In yet another embodiment, two or more of the sensors can communicate with one another (wired or wirelessly) to exchange data or control information.

The placement of the bone conducting element  1042  in this embodiment can reduce impact to the design of the eyeglasses. 
   In one embodiment, the electrical components associated with a temple arrangement, a temple adapter or a removable temple part is for enhancing the hearing of the person wearing the corresponding pair of glasses. There can be at least a microphone and a speaker in a temple arrangement, a temple adapter or removable temple part. The microphone can be close to an ear of the user when the glasses are worn by the user, and can be a directional microphone. The microphones can be a microphone in a temple adapter, such as the microphone  730  in  FIG. 7B ,  808  in  FIG. 8A ,  936  in  FIG. 9B , or  976  in  FIG. 9D . The microphones can be in a temple arrangement. The microphone in a temple arrangement can be attached to a temple tip, a temple fit-over or a temple cover. The microphones can be positioned to be in front of the user&#39;s ears so that the microphones will not be affected by the shadowing effect of the ears. The speaker can be inserted into the ear, as in some of the speakers previously described. 
   In another embodiment, there are two sets of microphones and speakers, such as in two temple arrangements, temple adapters or removable temple part. In the vicinity of each ear, there is a temple arrangement, temple adapter or removable temple part with its corresponding microphone and speaker. The microphones again can be directional, one pointing generally outwards in a position close to the left ear, and one pointing generally outwards in a position close to the right ear. Alternatively, the microphones can point forward. 
   The microphone and the speaker close to an ear do not have to be in very close proximity to each other, as in many hearing aids existing nowadays. They can be spaced apart by, such as, one to several inches, with the microphone being directional and pointing to the front and to either the left or the right of the user, and with the speaker pointing toward or inserted into the corresponding ear of the user. Such a distance apart can significantly reduce feedback effect of existing hearing aids. Another advantage of such a hearing enhancement device is that users may not need to be fitted into ears with ear molds. In any case, additional details on hearing enhancement are further described in the related applications that have been incorporated herein by reference, such as U.S. Provisional Patent Application No. 60/620,238, filed Oct. 18, 2004, and entitled “EYEGLASSES WITH HEARING ENHANCED AND OTHER AUDIO SIGNAL-GENERATING CAPABILITIES.” 
   The various embodiments of the invention noted above, whether temple arrangement, temple adapter or removable temple part, can have a cable or cord attached or attachable thereto. The cable or cord has one or more conductors. The cable or cord can serve to provide electrical signals to or receive electrical signals from the temple arrangement, the temple adapter or removable temple part. In one embodiment, one end of a cable or cord attaches to a temple arrangement, temple adapter or removable temple part (either permanently or via a connector) and the other end of the cable or cord attaches (either permanently or via a connector) to an electronic device. As an example, the electronic device can be an audio output device (e.g., audio player) or a communication device (e.g., mobile telephone). In a first example, the cable or cord could provide a male audio (stereo) connector at one end, and a pair of female audio connectors at the opposite end, each being for use with a different temple. In a second example, the cable or cord could provide a set of connectors, such as a male mini-phone connector (2.5 mm) and a male audio (stereo) connector, at one end, and one or a pair of female phone connectors at the opposite end. 
   In one embodiment, the cable or cord can also have a switch coupled thereto so as to permit a user to switch modes. For example, if the temple arrangement, temple adapter or removable temple part provides a speaker and microphone to a pair of eyeglasses, a switch on a cable or cord that connects the temple arrangement or temple adapter to an electronic device could provide different switch positions for different electronic devices or different functional modes of operation of a single electronic device. As an example, if the electronic device is (or operates as) an audio player, a first switch position could be used. Alternatively, if the electronic device is (or operates as) a mobile telephone, a second switch position could be used. Additional discussion of suitable cables and cords is provided in the related applications that have been incorporated herein by reference. 
   Electrical components can form an electronic module. The electronic module can provide radiation monitoring, wireless communication, enhanced hearing, etc. A radiation monitoring system can be partially or fully contained in a temple arrangement, temple adapter or removable temple part associated with a temple of a pair of glasses. Typically, the temple arrangement or temple adapter can be removable from the temple. The removable temple part is obviously removable from a corresponding remaining temple part. 
   In another embodiment, an electronic component in a temple arrangement, temple adapter or removable temple part interacts with another electronic component in another part (e.g., frame) of the glasses or in a device tethered to the glasses. For example, a temple of a pair of glasses holds one portion of an electronic circuit. That portion can include generic parts, such as a battery, that are applicable to different applications. Another portion of the electronic circuit is in a temple arrangement, temple adapter or removable temple part. This portion can be application specific, such as an electronic clock without a battery, or a temperature sensor. 
   In yet another embodiment, the electrical components can provide audio player capabilities. In such an embodiment, the electrical components can include audio file storage, an audio player and a battery. The electrical components may or may not include wireless communication circuitry. 
   Further, in an alternative embodiment, the output of an operation indicator can be audio. The audio output can be from one or more speakers associated with the frame of the eyeglasses. Such audio output can signal the user using natural language, voice synthesis, pre-recorded messages, etc. 
   In another embodiment, the electrical components can include a memory module. The memory module provides non-volatile data storage. For example, the memory module can be a portable (or removable) memory device (e.g., memory card). The memory module can, for example, store sensor information (which can be over an extended period of time). Such memory module can be remotely interrogated using wireless communication circuitry, or can be accessed through a wired connection with a tethered device. 
   In one embodiment, the electrical connection(s) can alternatively be used to allow information stored in the electrical components to be accessed or queried by a device. For example, when the electrical components include a memory module, the memory module can be accessed to read data (e.g., status information) stored therein. 
   As previously noted, the electrical components associated with a temple arrangement, a temple adapter and/or removable temple part can pertain to radiation monitoring circuitry. In such case, the electrical components within the temple arrangement, temple adapter or removable temple part alone or together with eyeglass electrical components can implement a radiation monitoring system. The radiation being monitored can, for example, pertain to one or more of UV, infrared and gamma radiation. In one embodiment, sunlight is considered as a type of radiation. In any case, additional details on radiation monitoring are further described in the related applications that have been incorporated herein by reference. 
   Also, the electrical components can pertain to health or fitness monitoring circuitry. In such case, the electrical components within the temple arrangement, the temple adapter removable temple part alone or together with eyeglass electrical components can implement a health or fitness monitoring system. Additional details on health or fitness monitoring are further described in the related applications that have been incorporated herein by reference. 
   In yet another embodiment, an electronic component in a temple arrangement, a temple adapter or removable temple part of a frame of eyeglasses interacts with an electronic component of an apparatus tethered to the eyeglasses to perform an operation. For example, a temple arrangement, a temple adapter removable temple part of a pair of eyeglasses holds one portion of an electronic system, and a tethered apparatus that tethers to the pair of eyeglasses includes another portion of the electronic system. 
   Still further, the invention can provide a new approach to marketing accessories, namely, electrical accessories, for eyewear. According to one method for providing temple arrangements, temple adapters and/or removable temple part for use with a pair of glasses, the method can initially provide a plurality of temple arrangements, temple adapters and/or removable temple part for a customer. This enables the customer to browse and select at least one temple arrangement, temple adapter or removable temple part. Each of the temple arrangements, temple adapters or removable temple part can have one or more electrical components at least partially embedded therein, with different temple arrangements, temple adapters or removable temple parts providing different electrical capabilities. Once a temple arrangement, temple adapter or removable temple part has been selected, the selected temple arrangement, temple adapter or removable temple part can be coupled to one of the corresponding temples of the eyewear (e.g., a pair of glasses). In the case where the selected temple arrangement is a temple tip, the selected temple tip is inserted onto (e.g., slid over) an end of the corresponding temple (after removing any previously installed temple tip if there was one). In the case where the selected temple adapter is to be coupled, the selected temple adapter can be attached to the corresponding temple. In the case where the selected removable temple part is to be coupled, the selected removable temple part can be attached to a remaining part (e.g., forward part) of the corresponding temple. Thereafter, the customer can make use of the eyewear with its associated electrical capabilities provided by the temple arrangement, temple adapters or removable temple part. 
   In one embodiment, once a temple arrangement, a temple adapter and/or removable temple part is provided to a customer, the customer can test the electrical capabilities of the pair of glasses. If the customer does not like the current selected temple arrangement, temple adapter or removable temple part, the customer can repeat the process by selecting and testing another temple arrangement, temple adapter or removable temple part. Before providing the eyewear with the temple arrangement, temple adapter or removable temple part, the customer can be required to pay a purchase (or rental) price for at least the temple arrangement, temple adapter or removable temple part. Thereafter, the customer can be permitted to return and replace the temple arrangement, temple adapter or removable temple part with another temple arrangement, temple adapter or removable temple part. Such returns or replacements can be available only for a limited period of time following their purchase. 
   Yet still another aspect of the invention relates to eyewear having an extended endpiece so as to facilitate placement of one or more electrical components at the extended endpiece. The one or more electrical components can operate independently or together with other electrical components provided elsewhere. For example, other electrical components can be provided in other regions of the frame for the eyewear. In one particular example, the other electrical components can be located in a bridge area of the frame for the eyewear. In such an example, given that the endpiece is extended, the one or more electrical components can be placed at the endpiece and thereby communicate with other electrical components in a front area (e.g., bridge region) or the other endpiece without having to communicate through a hinge or connector. 
     FIG. 11A  illustrates a pair of glasses  1100  according to one embodiment of the invention. The pair of glasses  1100  include a first lens holder  1102  and a second lens holder  1104 . The lens holders  1102  and  1104  are capable of receiving lens. The lens can be prescription lens or non-prescription lens. The first lens holder  1102  has a first side and a second side. The second lens holder  1104  has a first side and a second side. The pair of glasses  1100  also has a bridge  1106 . The bridge  1106  is coupled to the second side of the first lens holder  1102  and the first side of the second lens holder  1104 . The lens holders  1102  and  1104  and the bridge  1106  can be separate pieces or a single integral piece. The glasses  1100  can also be referred to as eyeglasses. 
   The pair of glasses  1100  also includes a first extended endpiece  1112  and a second extended endpiece  1113 . In addition, the pair of glasses  1100  includes a pair of temples, namely, a first temple  1108  and a second temple  1110 . The first extended endpiece  1112  connects to the first temple  1108  via a joint (or hinge)  1114 . The second extended endpiece  1113  connects to the second temple  1110  via a joint (or hinge)  1115 . The extended endpiece  1112  and  1113  are enlarged as compared to conventional endpieces. As a result, the respective joints (or hinges)  1114  and  1115  are set back from the respective lens holders  1102  and  1104 . For example, in one embodiment, the hinge  1115  is set back from the lens holder  1104  by between about 1-5 centimeters. One advantage of utilizing enlarged endpieces  1112  and  1113  as illustrated in  FIG. 11A  is that electrical components  1116  are able to the comfortably be provided in the extended endpieces  1112  and  1113 . Moreover, another advantage is that the electrical components  1116  within the extended endpiece  1113  can electrically coupled to other electrical components provided within the forward portion of the frame without having to electrically connect through a joint or hinge. As illustrated in  FIG. 11A , the extended endpiece  1113  provides electrical components  1116  at an inner surface of the extended endpiece  1113 . The electrical components  1116 , in this example, include a display  1118  and a plurality of switches  1120  (e.g., buttons). As an example, the electrical components  1116  can, for example, implement an electrical system (e.g., pedometer system, UV monitoring system, physical condition monitoring system, etc.). However, in the embodiment of the glasses  1100  illustrated in  FIG. 11A , the electrical components  1116  are provided in the extended endpiece  1113 . 
     FIG. 11B  illustrates the pair of glasses  1100  according to another embodiment of the invention. More particularly,  FIG. 11B  illustrates the pair of glasses  1100  illustrated in  FIG. 11A  where the electrical components  1116  are provided as a module  1122  internal to the extended endpiece  1113 . The module  1122  includes a plurality of interconnected electrical components, including the display  1118  and the switches  1120 . In addition, the glasses  1100  further include a separate electrical component  1124 . As illustrated in  FIG. 11B , the separate electrical component  1124  can be provided at the bridge  1106 . Still further, a conductive element (e.g., a wire) that electrically connects the module  1122  with the separate electrical component  1124  can be provided internal to the eyeglass frame, namely, internal to the lens holder of  1104 . The nature of the separate electrical component  1124  can vary depending upon application. In the case in which the module  1122  pertains to a pedometer system, the separate electrical component  1124  can pertain to a sensor used to measure heart rate of the user of the glasses  1100 .

The module  1122  can be inserted or removed from the cavity by way of the cover. 
     FIGS. 12A-12E  illustrate a side view of eyeglass frames having an extended temples according to several embodiment of the invention. In  FIG. 12A , a side view of a eyeglass frame  1200  includes a lens holder  1202 , an extended endpiece  1204  and a temple  1206 . The extended endpiece  1204  includes one or more electrical components  1208  partially or completely internal to the extended endpiece  1204 . In this embodiment, the manner by which the temple  1206  connects to the extended endpiece  1204  is not depicted. Hence, the temple  1206  can be integral with the extended endpiece  1200 , can be permanently coupled to the extended endpiece  1204 , or can be removably coupled to the extended endpiece  1204 . 
   The side view of an eyeglass frame  1220  illustrated in  FIG. 12B  is similar to the eyeglass frame  1200  illustrated in  FIG. 12A . However, in this embodiment, the temple  1206  is coupled to the extended endpiece  1204  by way of a joint (or hinge)  1210 .  FIG. 12C  illustrates the eyeglass frame  1220  with the temple  1206  being substantially closed with respect to the eyeglass frame  1220 . As noted in  FIG. 12C , the temple  1206  can rotate with respect to the extended endpiece  1204  by way of the joint (or hinge)  1210 . In this embodiment, the temple  1206  is able to be rotated as in conventional eyewear such that (i) the temples can be closed when not being worn to facilitate storage or (ii) the temples can be extended to an open position so that the eyeglasses can be worn. While retaining the traditional notion of the folding temples, the eyeglass frame  1220  causes the joint  1210  to be set back from the lens holder  1202  so that the endpiece is extended, which can facilitate including one or more electoral components within the endpiece. 
   The side view of an eyeglass frame  1230  illustrated in  FIG. 12D  is similar to the eyeglass frame  1200  illustrated in  FIG. 12A . However, in this embodiment, the temple  1206  is coupled to the extended endpiece  1204  by a linking temple piece  1232 . The linking temple piece  1232  couples to the extended endpiece  1204  by way of a joint (or hinge)  1234 . The joint  1234  allows the linking temple piece  1232  to rotate with respect to the extended endpiece  1204 . In addition, the linking temple piece  1232  includes a connector  1236  that is capable of receiving a corresponding connector  1238  associated with the temple  1206 . In this embodiment, the temple  1206  couples to the linking temple piece  1232  using the connectors  1236  and  1238  which provide physical connection (and optionally also electrical connection). The linking temple piece  1232  in-turn can couple to the extended endpiece  1204  by way of the joint (or hinge)  1234 . The temple  1206  is thus easily removable from the linking temple piece  1232  of the eyeglass frame  300 . 
   The side view of an eyeglass frame  1240  illustrated in  FIG. 12E  is similar to the eyeglass frame  1200  illustrated in  FIG. 12A . However, in this embodiment, the extended endpiece  1204  includes a first connector  1242 , and the temple  1206  includes a corresponding connector  1244 . Here, the temple  1206  can be removably connected to the extended endpiece  1204  by way of the connectors  1242  and  1244 . 
   According to still another embodiment of the invention, temples for eyeglass frames can be not only removable but also piecewise replaceable. In other words, an entire temple can be removed and replaced with respect to an eyeglass frame. In another implementation, a portion of a temple can be removed and replaced with another portion. Allowing temples of eyeglass frames to be removed and replaced facilitates incorporating different electronic modules that are internal to the temples (or temple portions) to the changed. Also, the different temple portions can have different design appearances that allow the design of the eyeglasses, namely the temples, to be altered as desired by a user. In other words, the temples or temple portions can be swappable. 
     FIG. 13A  illustrates a temple  1400  having multiple parts according to one embodiment of the invention. The temple  1400  includes a temple base  1402  that couples to a forward portion  1404  of an eyeglass frame. The forward portion  1404  can, for example, pertain to an endpiece or a forward portion of a temple. In addition, the temple  1400  includes a temple tip  1406  (or rearward portion). One end of the temple base  1302  can connect to the forward portion  1404  and the other end of the temple base can connect to the temple tip  1406 . As a result, the temple base  1402  and the temple tip  1406  can be replaced (individually or in combination) with other temple bases and temple tips. For example, the temple base  1402  and/or the temple tip  1406  could be removed and replaced with another temple base and/or temple tip having a different functional capability or a different ornamental appearance. 
     FIG. 13B  illustrates a portion of an eyeglass frame  1420  according to one embodiment of the invention. The portion of the eyeglass frame  1420  is similar to the portion of the eyeglass frames  1200  illustrated in  FIG. 12A . The difference is that the temple  1206  now explicitly illustrates a temple base  1422  and a temple tip  1424 . The temple base  1422  and a temple tip  1424  can be removed and replaced (individually or in combination) with respect to the eyeglass frame, namely, the extended endpiece  1204 . 
     FIG. 13C  illustrates a portion of an eyeglass frame  1340  according to another embodiment of the invention. The portion of the eyeglass frame  1440  is similar to the portion of the eyeglass frame  1200  illustrated in  FIG. 12A . However, in  FIG. 13C , the portion of the eyeglass frame  1440  includes a temple insert  1442 . The temple insert  1442  can include one or more electrical components  1444  internal to the temple insert  1442 . As illustrated in  FIG. 13C , the temple insert  1442  can be provided between the extended endpiece  1204  and the temple  1206 . Although not shown in  FIG. 13C , the connection between the temple insert  1442  and the extended endpiece  1204  or the temple  1206  can be through use of a joint (or hinge) or by way of connectors as discussed above. In this embodiment, the temple insert  1442  can provide electrical components that can interact with the electrical components  1208  within the extended endpiece  1200  or elsewhere within the eyeglass frame. Hence, a user can optionally include the temple insert  1442  between the temple  1206  and the extended endpiece  1204  to provide additional functionality to the eyeglasses. Then, when the additional functionalities not desired, the temple insert  1442  can be removed from the temple configuration.
