     FIELD OF THE INVENTION 
     The present invention relates generally to glasses and more particularly to glasses utilizing electrical components. 
     BACKGROUND OF THE INVENTION 
     Many of us have experienced the inconvenience of trying to listen to a piece of music from a portable device in an outdoor environment, particularly in cold weather. First, we remove the device from inside our jacket. Then, we take off our gloves to find the right song, connect the device to a headset, and put on the headset. After we have finished listening, we go through the process again to put the device back into our jacket. To a certain degree, we are somewhat used to such procedures. However, to look at this objectively, going through the multi-step process just to listen to a piece of music is cumbersome. Such inconvenient procedures are not limited to hearing music. For example, it may not be much easier for us to use the cell phones or cameras and the like. 
     It should be apparent from the foregoing that there is still a need to increase the ease of handling electronic devices. 
     SUMMARY OF THE INVENTION 
     In one embodiment, an eyeglass frame includes a lens holder, a first temple with a first end close to the lens holder and a second end further away, a second temple, an electrical connector and a printed circuit board. The printed circuit board with at least one electrical component attached thereon can be provided in the first temple. The connector can be provided close to the first end of the first temple, facing downward, and configured to be electrically connected to the at least one electrical component. 
     In another embodiment, an eyeglass frame includes a first printed circuit board with at least one electrical component. The first printed circuit board can be connected to an electrical component at the frame via a second printed circuit board. 
     Other aspects and advantages of the present invention will become apparent from the following detailed description, which, when taken in conjunction with the accompanying drawings, illustrates by way of example the principles of the invention.

     Same numerals in  FIGS. 1-24  are assigned to similar elements in all the figures. Embodiments of the invention are discussed below with reference to  FIGS. 1-24 . 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. 
     DETAILED DESCRIPTION OF THE INVENTION 
     A number of embodiments according to the present invention regarding glasses with one or more electrical components attached, partially embedded or fully embedded are described. Many of them are applicable to different types of glasses, such as sunglasses, auxiliary frames, fit-over glasses, prescription glasses, safety glasses, swim masks, and goggles, such as ski goggles. In a number of embodiments, the frames of the glasses have more surface area than frames with minimal structure. For example, the temple regions of the glasses can have a tapered profile. They are wider or broader when they are closer to the lens holders. Then they get narrower. In one embodiment, a wider or broader temple implies that the temple spans across a wider or broader area longitudinally down from the top of the head of the user.  FIG. 1  shows an example of such an embodiment. 
       FIG. 1  shows one embodiment  100  of the invention where there is a speaker  102  at least partially embedded in one of the temples  104  of the glasses  106 . The speaker  102  is closer to one end of the temple  104  than the other end. The end of the temple that the speaker  102  is closer to is the end that is in the vicinity of the lens holder or the hinge of the glasses  106 , instead of the end  108  that is free. The speaker can be partially embedded in the glasses. For example, the mouth of the speaker, where sometimes there can be small holes on a cover, can be exposed. 
     In the embodiment shown in  FIG. 1 , the speaker  102  outputs audio signals in the direction towards the user. In another embodiment, the speaker  102  outputs audio signals in the direction away from the user. For example, the mouth of the speaker  102  can be facing outwards away from the user. 
     There are different approaches to embed an electrical component into a pair of glasses. For example, the glasses can be made of plastic (e.g., plastic frames). One way to produce such frames is to first assemble electrical components onto a circuit board. The circuit board can be shaped to fit, for example, the temple of the glasses. The circuit board is placed into a mold. Then, hot, molten plastic is injected around the circuit board to form the temple piece of the glasses. To reduce weight, the wall of the glasses can be made relatively thin through injection molding techniques. 
     In another embodiment, the glasses have metallic frames. For example, the frames can be made of Titanium, which is a relatively light metal. Also, Titanium is relatively non-conductive and strong, and is quite immune to corrosion. Further, Titanium can be anodized or heat colored. 
     For glasses with metallic frames, to prevent circuits from being shorted or to reduce leakage current, one embodiment provides an insulating layer between the electrical components or circuit board and the metallic frames. One example of an insulting layer is a tape to encapsulate the electrical components. The tape is non-conducting so as to provide insulation and, to a certain degree, can also provide mechanical stiffness. One way to make such temples is to have two sheets of the metal die-stamped to form the two halves, or the two faces of the temple piece. A circuit board is made to fit into the space between the faces. Then, two die-cut pieces of insulator material (e.g., dielectric tape) can cover the top and the bottom surfaces of the circuit board. The board is then sandwiched between the faces to form the temple. In one example, the dielectric tape can be double-sided sticky tape, with one side sticking to the circuit board, and the other side sticking to the temple. An adhesive can be used to glue the two faces of the temple piece together. 
     In yet another embodiment, the frames are made of hard rubber. The frames can be manufactured in an approach similar to injection molding techniques, with circuit boards inserted into the mold along with the rubber at the time of molding. 
     Different types of speakers can be used, such as, standard, fixed-magnet/moving coil speakers; speakers with fixed-coil and a steel diaphragm; piezoelectric speakers; and electrostatic speakers. 
     In one embodiment, the glasses further include a tube, such as a plastic tube, extending from a speaker. The tube serves to guide sound generated by the speaker to one of the ears of the user.  FIG. 2  shows an embodiment where a tube  150  is located on the outside of a temple  152 . In another embodiment, the tube can be on the inside of a temple. 
     In one embodiment, the tube  150  can be rotated, such as from behind the temple  152  (if the tube is on the inside of the temple) to being downward at an angle towards one of the ears of the user, such as the position shown in  FIG. 2 . To increase flexibility, the tube can be attached to a rotating disk  154 , which allows rotation about the speaker. 
     In another embodiment, the tube is malleable. This allows the tube to be placed in different positions. 
     In one embodiment, the length of the tube is adjustable.  FIG. 3  shows such an embodiment  200  of a pair of glasses with a retractable tube  202 . In the figure, the tube is shown to be in its extended position. 
     To further enhance sound coupling, in one approach, there is a plug  156  at the end of the tube for inserting into an ear of the user. The plug can be an ear bud. The plug can provide a cushion, foam rubber or other materials. Such materials give comfort and/or enhance sound coupling to the ear canal. 
     In another approach, there is a funnel at the output of the speaker.  FIG. 4  shows the cross section of such a funnel from a speaker at a temple region of the glasses. As shown in  FIG. 4 , the speaker  254  sits on a speaker frame  252 , and the speaker  254  is electrically connected to a circuit board  256 . As sound is generated from the speaker  254 , the sound propagates to a tube  258  through a structure  260  in the shape of a funnel. Such a structure helps guide the sound to the tube (i.e., improved sound coupling). Also,  FIG. 4  shows the tube, which can be the tube  150  shown in  FIG. 2 , mounted onto the temple region of the glasses with a circular lip  262 . Such a lip  262  allows the tube  258  to rotate relative to the glasses. In the embodiment shown in  FIG. 4 , the speaker  254  is fully embedded in the glasses. 
     As an alternative to or in conjunction with the tube, the glasses can include a channel to likewise guide sound generated by the speaker to one of the ears of the user. For example, the channel can be formed within a temple. The temple also has an opening to output the sound towards the user&#39;s ear. 
       FIG. 1  shows one speaker at one of the temples. There can be more than one speaker at each temple. In one embodiment, there can also be at least one speaker at each temple. The two speakers can generate stereo effects. 
     In another embodiment, the glasses can provide four or more speakers to give a high fidelity sound or a surround sound effect. For example, each temple can include one speaker in front of the user&#39;s ear, and one speaker behind the user&#39;s ear. The different speakers can generate different portions or sections of the sound. Further, if a base (discussed below) or portable electronic device is coupled to the glasses, the base or portable electronic device can contain another speaker, such as a base or woofer speaker. Such embodiments enable the glasses to provide a personal high-fidelity sound or a surround-sound environment. 
     Electrical signals can be coupled to an electrical component, such as a speaker, in a pair of glasses through a number of mechanisms. In one embodiment, there is an electrical connector at least partially embedded in the glasses. In other words, at least a portion of the connector is inside the glasses. The connector is electrically coupled to the speaker (or other electrical component) by, for example, a conductor. The conductor can be on a printed-circuit board. In one embodiment, the conductor is also embedded in the glasses. 
     Regarding connectors,  FIG. 5  shows one embodiment where the connector is not a standard connector. The end  108  of the temple  104  of the glasses  106  shown in  FIG. 1  has a similar connector. In  FIG. 5 , the connector is a male plug or a male connector  300  at the end of a temple  302  of a pair of glasses. The connector  300  is connected to the speaker through, for example, one or more wires embedded in the temple. Electrical signals external to the glasses can then be coupled to the speaker (or other electrical component) through the plug. 
     As shown in  FIG. 5 , the free end of the temple  302  can have a relatively flat cross section. There can be one or more electrically-conductive contacts, such as  304  and  306 , on one or both of the flat surfaces of the temple. In  FIG. 5 , four contacts are shown on one surface of the temple. The contacts,  304  and  306 , can be metal pads or bumps. 
     In one embodiment, a non-standard connector can be made using printed-circuit board technologies. First, a printed-circuit board with printed conductors connected to metal contact bumps is produced. Then plastic is overmolded around the printed-circuit board, with the mold designed to shut off around the bumps or pads. The overmolded plastic can serve as the temple, and the pads would be left exposed. Thus, portions of the printed circuit board are covered by plastic, and areas with the bumps or pads are exposed for connection. These pads serve as the connectors for the glasses. 
     Regarding printed-circuit boards, there can be one or more circuit boards in the glasses. For example, there can be a circuit board in one of the temples of the glasses. Or, the circuits can be divided into two circuit boards, one in each temple of the glasses. The circuit boards can carry additional electrical components to be described below. 
     In one embodiment, the circuit boards are rigid. In another embodiment, the circuit boards are made of flexible materials, such as a polyimide sheet, like Kapton®. In one embodiment, the circuit board is configured or adapts to the shape of the temple in which it resides. 
     As shown in  FIG. 5 , the end of the temple  302  serves as a male connector (plug)  300 . The non-standard male connector  300  can be received by a non-standard female connector (plug)  310 . Typically, the female connector  310  makes electrical and physical connection through grabbing around the male plug. The female connector  310  can be connected to a cable  312 . 
       FIGS. 6A-6B  illustrate a process to make the non-standard female plug  310 . First, an electrical wire  354  is attached to a small sheet or piece of metal  356 .  FIG. 6A  shows a number of such wires, with a number of the metal sheets or pieces crimped to a hard PVC  358 . The figure shows the back side of the crimped board with the wires and with a number of holes, such as  360 . Then the frame is overmolded with a soft PVC.  FIG. 6B  shows a cross section of the overmolded frame  362  with the soft PVC. As shown in the figure, a number of the metal sheets, such as  364  and  366 , are exposed. They are the metal contacts in the female connector  310 . Instead of the above approach, alternatively, a wire can be attached to a sheet of metal by putting the wire between the metal and the plastic as the metal is crimped onto a plastic. When the temple (i.e., male connector  300 ) is inserted into the female plug, the soft PVC material stretches slightly, providing a spring-force to keep the contacts connected. 
     The hard PVC can have a hardness of over 80 durometer, while the soft PVC can have a hardness of less than 50 durometer. The hard PVC can be replaced by other materials, such as Polypropylene or cloth. The soft PVC can be replaced by Silicone, or a thermo-plastic elastomer, such as Kraton®. 
     Referring to both  FIG. 5  and  FIG. 6B , when the male connector  300  is inserted into the slot  314  of the female connector  310 , the metal pads,  304  and  306 , will get in contact, or mate, with the metal sheets,  364  and  366 . 
     In one embodiment, as long as the male connector  300  is pushed all the way into the female connector  310 , the pads are aligned correctly to the sheets for electrical connections. In another embodiment, there is an alignment mechanism to guide the position of the temple relative to the female connector so as to ensure the conductive sheets to be in contact with the conductive pads. For example, there can be a registration location to indicate that the male connector is at the appropriate position relative to the female connector. There can be an alignment extension, which can be a partial sphere, close to the end of the temple  302 , such as between the pads  304  and  306 , at  316 . And, there can be a corresponding alignment notch at the female connector  310 . When the extension is received or caught by the notch, the male connector  300  is in the appropriate position relative to the female connector  310 . In other words, the alignment is proper, and the pads and the sheets are in contact. 
       FIG. 5  shows the non-standard male connector  300  at one end of a temple of a pair of glasses. In yet another embodiment, a non-standard connector can be at another location.  FIG. 7  shows another example of a non-standard connector  400 . The connector  400  includes one or more conductive pads,  412  and  414 , on the top side of a temple  402 . The connector  400  is designed to receive another connector  406  that grabs onto the side of the temple  402 . There can be an indentation  404  on the temple  402  to receive the other connector  406 . The other connector  406  can include a top  420  and a bottom  416  clip. There are a number of conductive pads or sheets inside the other connector  406 . The indentation  404  provides an alignment to indicate where the top clip  420  of the other connector  406  should grab onto the temple  402  for connection. At that position, the conductive pads at the temple will be in contact with the conductive pads or sheets at the other connector  406 . There can also be another indentation  418  at the temple  402  to receive the bottom clip  416 . This can further enhance the alignment process and to secure the connection. 
     In  FIG. 7 , the other connector  406  is coupled to one end of a cord and a plug  408 , which can be inserted into a portable device  410 , can be connected to another end of the cord. The portable device, for example, can be a cell phone. This type of non-standard clip-type connector could be easily applied to the temple with one hand, for example, while the user is driving a car. 
     A number of non-standard connectors have been described. In another embodiment, the contacts are based on standard connectors, which can be off-the-shelf connectors.  FIGS. 8A-8E  show a number of examples of such connectors. 
     In one embodiment, the standard connector is a standard cylindrical plug located at the end of a temple. From a different perspective, the temple molds around the end of the plug.  FIG. 8A  shows one such embodiment. The plug  450  can be a standard audio connector or a 3-wire or three terminal plug, such as a 3.5 mm male stereo mini-phone plug. The 3 wires for such a plug are typically one for ground, the other two applicable for two signals, such as for creating stereo effects.  FIG. 8A  also shows the three wires,  452 ,  454  and  456 , inside the temple, extended from the plug  450 . These wires are for connection to electrical components of the glasses. 
     In one embodiment, the cylindrical plug  450  shown in  FIG. 8A  can be protected, encapsulated or shrouded. Or, at least a portion of the plug is protected, encapsulated or shrouded. Such protection can, for example, be for aesthetic reasons, or to prevent the plug from scratching the face of the user when the user is putting on the pair of glasses. In  FIG. 8A , the plug  450  is partially embedded in a temple. 
     Instead of a three terminal plug, other types of standard cylindrical plugs applicable to different embodiments of the present invention include a serial connector with 3 pins, typically one for ground, one for transmitting data (Tx) and the third for receiving data (Rx); or (b) a 2-wire connector, one served as ground, the other for carrying, such as power and modulated signals. 
     In yet another embodiment, instead of a cylindrical plug, the standard connector at the end of a temple of a pair of glasses is a USB or a FIREWIRE connector. 
     A number of embodiments have been described where the standard connector(s) at the glasses are male connectors. In yet another embodiment, the standard connector(s) in the glasses are female connectors. For example, there can be a 3.5 mm female stereo mini-phone plug at the end of a temple of a pair of glasses. At least a portion of the female connector can be protected, encapsulated or shrouded. For example, the female connector can be recessed within the end of a temple. 
       FIGS. 8B-8E  show different examples of standard connectors located or partially embedded not at the end of a temple of a pair of glasses, but, for example, on the side of the temple, such as on the inside surface or the outside surface of a temple.  FIG. 8B  shows a 0.10″ header plug  460 , commonly known as a MOLEX connector, on such a surface.  FIG. 8C  shows a female mini-phone plug  465  on such a surface.  FIG. 8D  shows a card connector  470  to receive a card  472 , such as a removable media card (e.g., memory card). There can be a cover  474  to secure and/or protect the media card  472  in place after it is inserted into the card connector  470 .  FIG. 8E  shows a female USB connector  480  on the inside surface of a temple  482  to receive a male USB connector  484 . 
       FIGS. 8F-8H  are diagrams pertaining to providing a removable electronic device with an eyeglass frame according to one embodiment of the invention.  FIG. 8F  illustrates a temple  490  that includes a connector  492 . The connector  492  includes an opening  494 . A removable electronic device can be coupled to the temple  490  using the connector  492 . More particularly,  FIG. 8G  illustrates a removable electronic device  496  that includes an electronic device housing  498  and a connector  499 . As an example, the removable electronic device  496  can be a memory storage device, sometimes referred to as a memory card.  FIG. 8H  illustrates the removable electronic device  496  coupled to the temple  490 . The removable electronic device  496  is coupled to one side of the temple  490 , such side can be either an inside or outside surface of the eyeglass frame. When the removable electronic device  496  is coupled to the temple  490 , the connector  499  of the removable electronic device  496  is inserted into the opening  494  of the connector  492 . Physical forces between the connector  499  and the connector  492  operate to secure the removable electronic device  496  to the temple  490 , yet permit the removable electronic device  496  to be removable therefrom. 
     In one embodiment, the connector  492  is not electrically connected to any electronic circuitry within the temple  490  or other parts of the eyeglass frame. In other words, the connector  492  provides a convenient means by which removable electronic devices can be coupled to the eyeglass frame. In another embodiment, the connector  492  can be coupled to electrical circuitry within the temple  490  or elsewhere within the eyeglass frame. Such an embodiment allows the electronic components within the removable electronic device  496  to be utilized with the electrical circuitry within the temple  490  or elsewhere within the eyeglass frame. For example, the removable electronic device  496  can provide data storage and/or other software modules to be utilized by or to utilize the other electrical circuitry within the temple  490  or elsewhere within the eyeglass frame. In any case, by attaching the removable electronic device  496  to the temple  490  (and thus the eyeglass frame), the removable electronic device  496  is able to be conveniently carried by the user of the eyeglass frame. In one implementation, the eyeglass frame, which includes the connector  492 , becomes a docking station for the removable electronic device  496 . As such, a variety of different removable electronic devices can be interconnected with the eyeglass frame, as desired. For example, the eyeglass frame can thus support different function or operations depending on the removable electronic device that is attached. For example, the eyeglass frame might operate as a camera, data storage device, FM radio, MP3 player, mobile telephone, pedometer, hearing enhancer, sun sensor, time piece, etc. 
     In one embodiment, the removable electronic device  496  can align itself with the orientation of the temple  490 , such as shown in  FIG. 8H . In  FIG. 8G , the electronic device housing  498  can be said to have an elongated housing. The configuration (e.g., shape) and/or color of the removable electronic device  496  can also be designed to conform or complement the design of the temple  490 . In one embodiment, the temple  490  might also have a recessed region to allow the portable electronic device to be less visually perceptible when attached to the temple  490  or to provide a more consistent contour of the temple  490 . 
     In one embodiment, the connector  499  is a male connector, and the connector  492  is a female connector or a similarly sized structure. In one implementation the connector  499  is a peripheral bus connector, such as a Universal Serial Bus (USB) connector. In such cases, the connector  492  can also be a peripheral bus connector (either electrically functional or non-functional as noted above). 
     Although the embodiment illustrated in  FIGS. 8F-8H  utilize connectors, namely, electrical connectors, the removable electronic device  496  could be attached to the temple in other ways. For example, other means to provide physical forces to hold the removable electronic device  496  in place can be used. 
       FIG. 8I  is a diagram of a temple of an eyeglass frame according to another embodiment of the invention. In this embodiment, the temple  490 ′ includes an opening  491  through which a cable  493  extends outward. The cable  493  has an electrical connector  495  connected at its end. The electrical connector  495  is electrically connected to electrical circuits within the temple  490 ′ or elsewhere within the eyeglass frame such as by way of one or more wires contained within the cable  493 . In one implementation, the length of the cable  493  is about one to four inches. The temple  490 ′ shown in  FIG. 8I  also includes a receptacle  497 . The receptacle  497  is affixed to or integral with the temple  490  to receive the electrical connector  495 . Typically, the receptacle  497  provides a holding mechanism for the electrical connector  495  when not been utilized. When the electrical connector  495  is being utilized, the electrical connector  495  is removed from the receptacle  497  and coupled to a corresponding counterpart connector of another electrical device. The cord  493  can provide ease-of-use so that the electrical connector  495  can be maneuvered to couple to the counterpart connector. In one embodiment, the temple  490 ′ can provide a recess for receiving the entire cable  493 , with the outer surface of the receptacle  497  being substantially flush to the surface of the temple  490 . So when the connector  495  is not in use, the connector  495  can be in the receptacle  497 , with the cable  493  in the recess. In one embodiment, when the cable  493  is in the recess and the connector  495  inside the receptacle  497 , the cable  493  has substantially no slack. Also, in another embodiment, the cable  493  can be retractable into the opening  491 . In the embodiment shown in  FIG. 8I , the electrical connector  495  is a male connector, and the receptacle  497  is a female connector or a similarly sized structure. 
     A number of standard and non-standard connectors have been described. Other types of connectors can also be used. In one embodiment, there is a connector adapter, which serves to transform such other type of connectors to a different interface. For example, an adapter can be a cord with one type of connector at one end and a different type of connector at the other end. 
     In one or more of the above embodiments, the glasses can access audio signals from another device through a connector at the glasses. The another device can be a multimedia asset players or a radio. 
     In one embodiment of the invention, the glasses have a storage medium (i.e., memory). The memory can be on a printed-circuit board and, for example, store 256 MBs or more. The memory can be a built-in or removable flash memory. The memory can be coupled to a device external to the glasses through one or more connectors at the glasses. As an example, a 256 MB flash memory is in one of the temples of a pair of glasses, and there is a USB connector at the free end of that temple to couple to an external device. 
     With the embedded storage medium, the glasses can upload information in the memory to or download information into the memory from an external device, such as a computer. A user can plug the glasses into the computer through a connector, either directly, or indirectly, with, for example, an intermediate wire in between. The user can store files in the glasses. Such an embodiment should reduce the chances of the user losing the files because the user has to lose the glasses as well. 
     In yet another embodiment of the invention, a pair of glasses includes a multimedia asset player, such as a MP3 player.  FIG. 9  shows some of the electrical components for a MP3 player  500  according to an embodiment of the invention. The player  500  includes a speaker  502  and a data bus  512 , which facilitates data transfer among, for example, a processor  506 , a storage device  510 , and a coder/decoder (CODEC)  504 . The processor  506 , which can be a microprocessor or controller, controls the operation of the player  500 . The storage device  510  stores the multimedia assets, such as MP3 files, or other types of media data that are appropriately formatted. In one example, the MP3 files are digitally encoded songs or other types of audio signals. The storage device  510  can include a number of separate storage elements. For example, the device  510  can be a flash memory device, or a minidisk device, and a cache, which can improve the access time and reduce power consumption of the storage device. The storage device  510  typically also includes a Read-Only Memory (ROM), which stores programs, utilities or processes to be executed in a non-volatile manner. The player  500  can also include a RAM, such as for the cache. 
     Once a media asset, such as a song, is selected to be played, the processor  506  would supply the asset to the CODEC  504 , which decompresses the asset and produces analog output signals for the speaker  502 . In one embodiment, the bus  512  is also coupled to an input/output device  508 , which would allow a user to upload songs in the glasses to an external instrument, such as a computer, or download songs from the instrument to the glasses. 
     There are different approaches to select a song. In one embodiment, the songs or the media assets can be categorized in the MP3 player, and the categorization can be hierarchical, with multiple levels in the hierarchy. To illustrate, assume that there are three levels. The top level can be the name of the singer; the second level can be the time period when the asset was produced, and the third level can be the names of the songs. The entries, such as the name of the singer, can be abbreviated. There can be a small display and a control knob to allow a user to scroll down entries in a level. By pushing the knob, the user selects an entry, which can lead the user to a lower level. There can be an entry for moving up a level also. In another embodiment, the display is a touch-screen display, allowing entries to be entered directly on the display. In yet another embodiment, entries can be selected based on voice recognition. 
     A number of embodiments have been described with the glasses having a connector. In one embodiment, the glasses can have more than one connector. For example, a pair of glasses with two connectors also has a speaker. One connector is, for example, at a broad side of a temple, as in  FIG. 8D . The connector can be for coupling to multimedia assets of a MP3 player. Another connector is, for example, at the end of a temple, as in  FIG. 8A . That connector can couple power to the glasses. The speaker can play the multimedia assets accessed from one connector, based on power from another connector. 
     As described, power (e.g., external power source) can be coupled to the glasses through a connector. In one embodiment, the power source is embedded inside or inserted into the glasses. Different types of power sources are applicable. For example, the power source can be a battery, a fuel cell, a solar cell, or a re-chargeable battery. The rechargeable battery can be charged through a connector at the glasses. 
     In an earlier application, namely, U.S. Provisional Patent Application No. 60/509,631, filed Oct. 9, 2003, and entitled “TETHERED ELECTRICAL COMPONENTS FOR EYEGLASSES,” which has been incorporated herein by reference, there can be a base connected to the glasses through a cord. The cord can be just a piece of flexible conductor encapsulated by a flexible insulator. Typically, a cord includes a number of electrical wires or conductors. There can be one or more electrical components in the base, and there can also be one or more electrical components in the cord. The different types of connectors previously described can be located in the base. In one embodiment, a power source is an electrical component in the base tethered to a pair of glasses. In another embodiment, the glasses are tethered to a base that has a connector. The connector is connected to and draws power from an external electronic device. In this embodiment, electrical components in the glasses draw power from the external electronic devices. 
       FIG. 10  shows an embodiment where a user  550  is wearing a pair of glasses  552 , which include electrical components. There are also tethered electrical components in a base  554 , which is connected to the glasses  552  through a cord  556 . In addition, there is a wire  558  connected to a connector at the base  554  to a portable electronic device  560 . The portable device  560  can be (a) a multimedia device, such as a MP3 player/recorder or a minidisk players, (b) a wireless communication device, such as a cell phone, or (c) a personal digital assistant, or other types of portable devices with computing and/or entertaining and/or communication capabilities. 
     Note that instead of connecting to the portable electronic device  560  through the base  554 , in another embodiment, the glasses  552  directly connect to the portable device  560  through a cord. 
     In one embodiment, there is an attachment device  562 , such as a pin or clip. The attachment device attaches at least a part of the glasses to the user&#39;s clothing. The attachment device  562  can serve to attach the cord  556  and/or the wire  558  and/or the base  554  to the user&#39;s clothing. The attachment can also be through other mechanisms, such as Velcro. 
     In a number of embodiments, the speaker described is assumed to emit audio signals. In one embodiment, the speaker emits ultrasonic signals. The glasses can be used, for example, as an insect repellant by transmitting ultrasound to repel insects, such as mosquitoes. In this embodiment, the one or more speakers broadcast the ultrasonic signals away from the user. In other words, the speakers face outwards, not inwards towards the user. In this embodiment, the glasses, which can include a base, also has a power source to provide power to the speaker. There can also be a control knob to turn the one or more speakers on/off on the glasses. There will be additional discussions on the control knob below. 
     In another embodiment, the glasses generating ultrasonic signals can be used to produce audio signals that are more directional. For example, two ultrasonic signals are generated by a speaker in the glasses, with their difference frequencies being the audio signals. The audio signals generated based on mixing the two ultrasonic signals can be much more directional than audio signals directly generated from the speaker. 
     Referring back to  FIG. 1 , in one embodiment, the glasses include a microphone  110 . The microphone  110  can be at the end of a temple  104  close to a lens holder  112 . Or, the microphone  110  can be in the lens holder  112 , located directly adjacent to the temple  104 . In yet another embodiment, there can be a small protrusion extending down from the temple to house the microphone. 
     With glasses having a microphone, one can use the glasses to record voices into, for example, a storage medium. The storage medium can be in the glasses, or can be in a base or a portable device attached to the glasses. 
     Different types of microphones can be used. For example, they can be electret microphones, crystal microphones, resistance microphones, piezoelectric microphones or moving-coil microphones. 
     In one embodiment, the glasses with a microphone also include a speaker that can generate directional sound. A user can speak into the microphone and his message can be transmitted from the glasses in a more directional manner. 
     In another embodiment, the glasses also include a notification electrical component to provide a notification to the user wearing the glasses. The notification can be to notify, alert or display information to the user. There can be a display located at the inside  114  of the lens holder, or at the vicinity of the junction  116  or the hinge of a lens holder and its corresponding temple facing the user. Or, there can be a display at the inside surface of a temple, or at other locations on the glasses. The display can be one or more light emitting diodes. To alert the user, one or more diodes can blink. The blinking can be of a specific sequence. Instead of diodes, the display can be a liquid crystal display. The display can provide indications or information to the user. For example, a number or a variable-height bar can be shown. Other than visual indications, the notification or alert can be audio, like a beeper. 
     In one embodiment, the notification electrical component is for selecting a multimedia asset in a multimedia asset player in a pair of glasses for the multimedia to play. The multimedia asset player can be a MP3 player. 
     A number of embodiments of the present invention have been described where electrical signals are transmitted to or from a pair of glasses through a physical connection. In one embodiment, electrical signals are wirelessly coupled to a pair of glasses. The coupling can be short range or long range. The coupling can be directly to the glasses, or to a base connected to a pair of glasses. The glasses with wireless coupling capabilities can be used to couple to a Bluetooth network, the Internet, a WiFi network, a WiMax network, a cell-phone network or other types of networks. The coupling can also be through a point-to-point link, such as an infrared link. In different embodiments, the glasses provide wireless communication capability for its user. In this regard, the glasses contain wireless communications circuitry that enables the eyeglasses to communicate in a wireless manner, to, for example, a wireless communication device (e.g. mobile telephone), a portable computing device (e.g. Personal Digital Assistant (PDA), handheld computer or wearable computer), or an entertainment device (e.g., stereo system, television, media player (portable or stationary)). 
       FIGS. 11A-11B  show examples of some of the electrical components in or tethered to a pair of glasses for wireless connections, according to embodiments of the present invention. In  FIG. 11A , a high frequency or RF antenna  602  wirelessly captures high frequency or RF signals for RF transceiver circuits  604 . If the transceiver circuits are for a conventional superheterodyne system, the transceiver circuits  604  mix the RF signals down to IF signals. Then the IF signals are processed by baseband circuits. Digital outputs from the baseband circuits are coupled to a processor  608  for analysis and synthesis. 
     Outputs from the processor  608  are fed to a D-to-A converter  610  to generate audio signals for a speaker  612 . Similarly, audio analog signals from a microphone  614  can be fed to an A-to-D converter  616  to generate digital low frequency signals for the processor  608  and then to the RF transceiver circuits  604 . The low frequency signals are up-converted by the RF transceiver circuits  604  and wirelessly transmitted by the antenna  602 . 
     In another embodiment, digital conversion is moved closer to the antenna. For example, instead of mixing RF into IF signals, the RF transceiver circuits  604  directly perform digital conversion from the RF signals. 
     Typically, high frequency filters are used at the front end of the RF transceiver circuits  604  for the RF signals. In one embodiment, to save space, FBAR (film bulk acoustic resonator) duplexer is employed. A set of piezoelectric filters can be used to separate incoming and outgoing signals. For cell phone operation, such filters can enable a user to hear and speak simultaneously. A number of these electronic devices can be on a circuit board in the glasses. Or, some of the devices are in the glasses, while other in the base tethered to the glasses. 
       FIG. 11B  shows another example of some of the electrical components in or tethered to a pair of glasses for wireless connections according to the present invention. In this embodiment, there does not need to have digital data. A speaker  620  and a microphone  622  are connected to an analog interface circuit  624 , which is coupled to a RF transceiver circuit  626  and an antenna  628 . For the speaker application, the transceiver circuit  626  mixes the RF signals down into IF signals, which are converted by the analog interface circuit  624  into analog signals for the speaker  620 . Similarly, for the microphone application, its analog signals are converted into the IF signals by the analog interface circuit  624  to be up converted by the transceiver circuit  626  into RF signals for the antenna  628 . These types of circuitry are suitable for, such as, simple radios, analog cell phones, CB radios, walkee-talkees, police radios or intercom systems. 
     In one embodiment, most of the electrical components are not in the glasses. The pair of glasses includes an antenna to capture the wireless signals, and a connector. The wireless signals captured are transmitted through the connector to electrical circuits external to the glasses. 
     A number of processors have been described. The processors can use different types of operating systems. In one embodiment, Symbian Operating Systems are used. In another embodiment, operating systems, such as TinyOS, are used. The operating system could be programmed in C++ and then compiled into machine codes. 
     For privacy protection, signals can be encrypted before transmission. Encryption can take significant computation power, and may generate a fair amount of heat. In one embodiment, encryption capabilities are located in a base tethered to the glasses. There can be a fan inside the base. The fan can be turned on during encryption. In another embodiment, the fan is activated during other high capacity uses for heat dissipation purposes. 
     In yet another embodiment, there is a fan in the glasses. The fan is located at a temple of the glasses, in the region close to its lens holder. The fan is used to cool the wearer of the glasses. 
     In one embodiment, a pair of glasses has access to voice recognition software. The software can be embedded in (a) the glasses, (b) a base tethered to the glasses, (c) a portable device wired or wirelessly coupled to the glasses or to the base, or (d) a computing system wired or wirelessly coupled to the glasses. Or, the software or firmware can be in more than one of the above devices. 
     Glasses that can couple to signals wirelessly can be used in different applications. For example, the glasses can be a cell phone wireless head set, such as a Bluetooth cordless headset. Such short-distance wireless technologies allow the headset to connect to the user&#39;s cell phone without a wire. This would allow the user to drive, eat or perform other functions without getting tangled in a pesky wire. 
     In one embodiment, the cell phone is a VOIP (voice over Internet protocol) phone. 
     In one embodiment, for the glasses operating as a cell phone head set, the head set includes active noise cancellation mechanism. For example, the glasses include two microphones. One microphone is for capturing the voice of the user. But the microphone captures ambient noise also. It can be embedded in a protrusion extending from the end of the temple close to a lens holder, towards the mouth of the user, as the microphone  110  in  FIG. 1 . Another microphone can be located at the top of one of the lens holders pointing away from the mouth of the user. This microphone is for capturing ambient noise. As a first order approximation, outputs from the two microphones could be subtracted from each other to provide voice signals with noise reduced. 
     In yet another embodiment, the glasses with wireless coupling capabilities also have a multimedia asset player, such as a MP3 player. The glasses can be used to receive music directly in digital format over, for example, a data-capable network of a mobile operator. The music can be received, for example, at a speed of 16 Kbits per second, providing sound quality close to compact disc. If the music is transmitted in a compressed manner, such as in a MP3 format, then the music data can be received at a much lower speed. In one embodiment, the glasses also have a microphone and can serve as a cellular phone or a wireless headset of a cellular phone. 
     In yet another embodiment, the glasses can serve as a radio, again through electrical components in or tethered to the glasses. In this embodiment, the glasses can include a tuner with one or more control knobs. The knobs can be used to select channels and to set the volume. 
     In one embodiment, a pair of glasses allows personalization by including a preference indicator. The indicator allows a user to provide his preference, such as on whatever is being output by the glasses. In one example, the glasses also has a radio having a speaker and with electrical components for wireless connection. In this example, the indicator can be used by the user to provide his preference regarding whatever is being played by the radio at that time. This preference can be wirelessly transmitted from the glasses to a third party. To illustrate, when the user is listening to a piece of music, the user can indicate he likes the piece of music by pressing a control knob on the glasses. This piece of preference information is then transmitted and received by a service provider, which is then informed of the user&#39;s preference. Instead of a control knob, in another embodiment, the preference indicator is a system with a microphone and voice recognition software. The user can indicate his preference vocally. 
     In another example regarding the personalization process, the glasses can serve as a multimedia asset player, such as a MP3 player. The song that the user has shown preference can be stored in a storage device, which can be in the glasses. 
       FIG. 12  shows a process  650  according to one embodiment of the present invention for a personalized radio. 
     Initially, a pair of glasses according to the present invention receives  652  a piece of music from a radio station. That piece of music is stored  654  in a buffer or a temporary storage area. This temporary storage area can be in the glasses or tethered to the glasses. The piece of music is also sent  656  to a speaker in the glasses. 
     Assume that the user likes the music. Based on the preference indicator, the user shows his preference. After the glasses receive  658  an indication of the user&#39;s preference, the glasses determine  660  the song corresponding to the indication. That piece of music can then be moved  662  from the buffer to a permanent storage area, such as into a flash memory. This would then allow the user to subsequently access the piece of music. 
     There are different ways to determine  660  the song or the content being played by the radio corresponding to the indication. For example, one rule is that when the user pushes the preference button or voices his preference, the song (or media asset or media file) that is being played is the one the user likes. Since the operating system knows what song is being played at what time, based on the rule, the song of preference is determined. Another rule is that when the user shows his preference, and there is no song being played at that instance, the song immediately preceding the break is the song of preference. 
     In another embodiment, the glasses can get  664  an identification for the song of preference. For example, the glasses can ask the user to provide an identification for the piece of music. This identification can be the type of music, the singer, the name of the music or other identification. In another embodiment, there can be meta data embedded, such as in the beginning part of the music (or media asset). Having such meta data embedded is not uncommon for music in digital format. The meta data can include identifications for the music. The glasses can get  664  such identification. Based on the identification, the song is categorized  666  accordingly, such as grouped with other songs having the same identification. Such categorization process would enhance the ease of accessing the song by the user at a later time. 
     A number of control knobs have been described.  FIG. 13  shows a number of attributes  700  regarding control knobs according to the present invention. The knobs can be of different physical structure  702 . For example, a control knob can be a roller, a switch or a push-button. A control knob serving as an up/down controller can use two buttons, or a roller. 
     A control knob can be more intelligent  704 . For example, a push-button control knob can serve different purposes depending on the duration the knob is being pushed. If a user pushes it for more than three seconds, the knob serves as an on-off toggle switch. In another example, a knob can serve multiple purposes, and the specific purpose depends on the number of times the knob is pushed. 
     A knob can also be programmed. A user can connect the glasses to a computer and program the knob accordingly. For example, one can program a knob such that if the knob is pushed more than three seconds, the knob would serve as an on/off switch for the glasses. As another example, a knob can provide reset to delete certain information previously captured by a process and to allow re-starting the process. 
     The location  706  of a control knob can vary for different applications. A control knob can be located on the glasses. A control knob can be on the top, the side or the bottom of the temple. A control knob can be located at the inside of a temple facing the user. Assume that there are a number of control knobs and all of them are on the edges of a temple, except one. By being at a position different from other control knobs, this knob can serve a specific purpose. For example, it can be an on/off control knob. In yet another embodiment, a control knob can be located in a base tethered to the glasses. 
     The number  708  of control knobs can vary depending on operations. For example, there is an on/off control knob and a volume up/down control knob. If the glasses are used for cell phone headset application, in one embodiment, there is also an answer/hang-up control knob. If the glasses serve as a radio, in one embodiment, there is also a tuning control knob, which can be two push buttons. If the glasses serve as a CD player, in one embodiment, there is a play control knob, a stop control knob, and a skip forward/backward control knob. If the glasses serve as a multimedia asset player, such as a MP3 player, in one embodiment, there is a save-this-song control knob, a skip-forward/backward-song control knob and a select-song-to-play control knob. 
     A number of embodiments of the present invention have been described regarding audio signals. In one embodiment, the glasses further serve as a camera. 
       FIG. 14  shows one embodiment of electrical components in a pair of glasses with image capturing capabilities. A processor  752  is coupled to a CCD interface chip  754  and then to a CCD chip  756 . Images focused by a lens  758  are captured and collected by the CCD chip. In another embodiment, there is also be a flash controller  760  connected to the processor  752  to control a flash  762 . 
     In one embodiment, a number of pixels of the CCD chip  756  are used as light sensors. The pixels can be used to adjust the sensitivity of the CCD chip  756  based on the amount of ambient light. For example, if the outside environment is dim, it would take a longer period of time to collect enough charges by the CCD chip  756  to re-create the image. This implies that the integration time of the CCD chip  756  should increase. 
     In yet another embodiment, the camera can pertain to a video camera. The capacity of the memory  753  increases so as to store the video images. 
     In one embodiment, the glasses do not offer adjustment on the image distance. The CCD chip  756  can be located, for example, at the focal point of the lens  758 . In another embodiment, there is an image distance control knob. For example, a mechanical lever can be pre-programmed or pre-set to move the lens to one or more different positions. One position can be for close-up shots, such as objects from 2 to 4 ft, and another for scenic or vista images, such as objects greater than 6 ft. 
     Depending on the embodiment, electrical components of a camera can be in a pair of glasses, and/or a base tethered to the glasses, and/or a portable device tethered to the glasses or to the base. For example, the memory  753  can be in the base tethered to the glasses. 
     The location of the lens  758  can vary depending on the embodiment. In one embodiment, referring to  FIG. 1 , one location is at the bridge of the glasses, with the lens of the camera facing forward. In this situation, what the user sees is substantially what the captured image would be. In other words, in a general sense, what the user sees is what the user gets. With such an embodiment, it is relatively easy for a user to take pictures, hands-free. In another embodiment, another location for the lens  758  are at a side portion adjacent to a lens holder, before the joint of the corresponding temple, such as at  116  in  FIG. 1 . Again, the lens of the camera faces forward. Some of the electrical components of the camera can be in that location, and other components in the temple  104 . These components are electrically connected through one of the joints, such as with a flexible pc board. In yet another embodiment, the lens  758  can face sideways and outwards in a temple of a pair of glasses, towards the left or right side of the user. 
     Regarding storing the images, in one embodiment, the images are stored locally. One approach to determine which image to store is the first-in-first-out approach. Once the camera is turned on, the camera takes pictures continually in an automatic mode, such as once every few seconds. When the memory becomes full or under other pre-set or pre-programmed condition, the first picture stored will be deleted when the next picture comes in. In another embodiment, the digital content in one picture is compared to the digital content in, for example, the fifth picture further down. If the difference between the two is not more than a pre-set threshold, the four pictures in between will be deleted. One approach to determine the difference is by comparing the total charges collected by the CCD chip for the two images. If the two sets of charges do not differ by more than a certain threshold, the images in between would be deleted. 
     The images captured can also be stored at a remote site. For example, the glasses can upload the images to a computer, wirelessly or through a wired connection from a connector at the glasses. 
       FIG. 15  shows an operation  800  of taking certain actions based on images captured by a pair of glasses with a wireless transceiver, according to one embodiment of the invention. This operation can be used by a police officer on patrol. Before the officer gets out of his patrol vehicle to confront a suspect, the officer can inform the station. At that point, the camera is turned on  802 . 
     There can be different approaches to turn on the camera. In one embodiment, an operator at the station can remind the officer to turn on the camera. Or, the operator can remotely turn on the camera. In yet another embodiment, the camera can be automatically turned on under certain condition. One such condition is that if the camera is out of the patrol vehicle, the camera is automatically turned on. With the glasses having the capability to wirelessly communicate with the patrol vehicle, one method to detect if the glasses are out of the patrol vehicle is based on the wireless signal strength of the glasses. The patrol vehicle can detect the signal strength of the wireless signals, which depends on the distance between glasses and the vehicle. A threshold can be set. If the signal strength is below the preset threshold, the glasses would be assumed to be out of the car, and the camera would be automatically turned on. 
     After the camera is turned on  802 , the glasses start to continually take  804  pictures, such as once every few seconds. The pictures taken are automatically transmitted back  806  to the patrol vehicle in a wireless manner. In this situation, the patrol vehicle serves as a hub, which stores the pictures. Then, the hub re-transmits  808  the pictures back to the station. Note that the pictures can be compressed by standard algorithms before they are transmitted. This compression mechanism can be performed by a computer in the patrol vehicle. When the station gets the pictures, they are de-compressed before being viewed, such as by the operator. The pictures enable the operator at the station to see what the officer is confronting. This effectively allows the operator at the station to perform real-time monitoring of or for the officer. If it is a high risk situation, the operator can quickly react  810 , such as by dispatching additional support for the officer. In one embodiment, the glasses can include not only a camera but also a microphone for audio pickup, such as sounds from the officer, suspect, witness or environmental sounds (such as door opening, gun shot, etc.). 
     Regarding ownership of the glasses, the user can own the glasses. In one embodiment, the user leases the glasses from a provider. For example, the user leases a ski goggle with a camera. After the user turns on the camera, as the user skis, the goggle automatically takes pictures. Later, the user can return the goggle to the provider or a kiosk, where the pictures can be retrieved and/or stored. Alternatively, the goggle can include a wireless transceiver and the images could be uploaded continually or automatically to the provider or the kiosk via a wireless network. The provider or the kiosk can transmit the images to a website, such as a website associated with the user. In another embodiment, the user picks up hardcopies of the images, e.g., a CD with the images or a DVD with the video, from the provider or the kiosk. 
     In one embodiment, the glasses allow the user to enter his identification. This can be done, for example, through a control knob at the glasses. Such identification is then linked to the images. Based on the identification, the user can return to the provider or kiosk at a subsequent time to pick up the images previously left behind. 
     In yet another embodiment, the pair of glasses with a camera also has a speaker and a wireless transceiver. It can be used to remotely control or direct the user wearing the glasses.  FIG. 16  shows one such operation  850  according to one embodiment. 
     To illustrate the operation  850 , assume that the user is a paramedic helping a patient. The glasses continually take pictures  852  of objects directly in front of the paramedic, such as images around four feet away from the eyes of the paramedic. The pictures are wirelessly transmitted  854  to a remote site, such as a hospital, to be viewed by a doctor. Again, this transmission can be a two-step process. For example, pictures can be transmitted to the paramedic&#39;s ambulance, which can then re-transmit to the remote site. The first transmission from the glasses to the ambulance can be through a low-power, short-range, broadband, wireless transmission protocol. The second transmission from the ambulance to the hospital can be through a much longer-range, higher power, broadband, wireless transmission protocol. Again, compression and de-compression techniques can be used to enhance the rate of transmission by reducing the amount of data to be transmitted. 
     Based on the images, the doctor sends out voice messages to the paramedic. These messages are wirelessly transmitted to and received  856  by the glasses. The speaker in the glasses outputs  858  the messages to the paramedic. 
     In another embodiment, the glasses also have a microphone, which allows the paramedic to communicate directly with the doctor also. 
     In one embodiment, the glasses can take pictures and can be a multimedia asset player. Pictures and the multimedia assets can share the same memory storage device. In this situation, the capacity for the multimedia assets and pictures can be interrelated. For example, a user can take more pictures if there are less multimedia assets, such as fewer songs in the storage device. 
     A number of embodiments have been described regarding electrical components in the temples of glasses. The locations selected are for illustration purposes. In other embodiments, some of the components are embedded fully or partially in other areas of the glasses, such as the lens holders or the bridges of the glasses. For example, there are glasses where there are shields at the edges of the lens holders of the glasses. These shields can wrap around, or better conform to the profile of, the face of the wearer. There can be transparent or translucent windows on these shields also. The shields are not limited to be in primary frames. They can be in, for example, fit-over glasses, auxiliary frames or safety glasses. To illustrate, in fit-over glasses, such shields can go over or cover at least a portion of the primary frames. One or more electrical components can be in such shields. In still another embodiment, one or more electrical components can be in a strap tied to the corresponding eyewear, such as a sports strap tied to the corresponding sports eyewear. For example, the one or more electrical components can be at least partially embedded in or attached to a strap. As one particular example, an audio player or wireless communication module can be at least partially embedded in or attached to the strap. The strap may also provide electrical conductors (that are attached or internal to the strap). Such electrical conductors can be coupled to a speaker to produce audio output to the speaker, or can be coupled to a microphone to receive audio input from the microphone. The speaker and/or microphone can also be attached to or integral with the strap. 
     Note that in one embodiment, a pair of glasses does not have to include lenses. Also, a number of embodiments have been described with a pair of glasses tethered to a base. In one embodiment, a pair of glasses includes a base and a cord connecting the base to the glasses. 
     In yet another embodiment, a pair of glasses also includes a sensor.  FIG. 17A  is a chart  900  that depicts examples of sensors in 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 eyewear is assumed to be worn. The motion detector can, for example, be achieved by a mechanical means 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 the end of the temple, close to its hinge. If the temperature differential between the two sensors is beyond a certain preset value, the eyewear 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 fully extended outwards, the switch is turned on. The switch can be a pin. 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 ultraviolet radiation, temperature (e.g., ambient temperature), pressure, light, humidity and toxins (e.g., chemicals, radiation, 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 physical 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 sense the 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 sensors can by 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 auxiliary sensors can communicate with one another (wired or wirelessly) to exchange data or control information. 
     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 particularly common for wire or metal frames. 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 tip. There can also be a connector, such as the connector  300  shown in  FIG. 5 , at the temple tip. In another embodiment, the temple tip can include a female connector, which can be similar to the female connector  310  shown in  FIG. 6B . As the temple tip grabs onto the main body of the temple, the female connector can make electrical contact with 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 a lot of difficulties. Such a temple tip can be an after-market component, with different temple tips having different electrical components to serve different functions. 
       FIG. 17B  is a diagram of a temple arrangement  910  according to one embodiment of the invention. In this arrangement, a temple tip is not considered as a part of the temple. The temple arrangement  910  includes a temple  912  that is associated with a pair of eyeglasses. Over the end of the temple  912  that is opposite the associated lens holder, a temple tip  914  is provided. The temple tip  914  can be held to the temple  912  by frictional forces and/or adhesive. The temple tip  914  includes at least one electrical component  916  that is at least partially embedded therein. The temple tip  914  can be manufactured and delivered to resellers or retailers as such. Alternatively, the temple tip  914  can be separately provided as an optional replacement temple tip for an existing temple tip. Hence, as after manufacture, upgrade to the eyewear can be had through replacing the existing temple tip with the replacement temple tip. The colors and shapes of the temple tip  914  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 tip that reasonably matches the color and shape of the temple or that provides an altered appearance as desired by the user. 
     Besides a replacement temple tip such as illustrated in  FIG. 17B , a temple tip can also be effectively modified by a fit-over temple or temple cover.  FIG. 17C  is a diagram of a temple cover  920  that at least partially covers a temple (e.g., temple  912 ) according to one embodiment of the invention. As another example, the temple cover  920  can be a fabric or other material, such as a sock or sleeve, that slides over and at least partially covers a temple tip. The temple cover  920  can include at one electrical component  922  that is either attached thereto or at least partially embedded therein. The temple cover  920  can also include an opening  924  so as to received a temple or a temple tip. The temple cover  920  can be held to a temple by frictional forces and/or adhesive.  FIG. 17D  is a diagram of a fit-over temple  926  that at least partially fits over a temple according to one embodiment of the invention. For example, the fit-over temple  926  can at least partial fit-over a temple tip. The fit-over temple  926  includes at one electrical component  928  that is either attached thereto or at least partially embedded therein. The fit-over temple  926  can also include an opening  930  so as to receive a temple. The fit-over temple  926  can be held to a temple by frictional forces and/or adhesive. As an example, the fit-over temple  926  can be plastic or other material. The colors and shapes of the fit-over temple  926  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 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. 
     In one embodiment, a 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. 
     In one embodiment, an electrical component is a component of an electrical circuit, and the electrical circuit is for performing at least a desired, intended or predetermined function. 
     A number of embodiments have been described above for an eyeglass frame, i.e., primary frame, are also applicable to an auxiliary frame. An auxiliary frame can attach to a primary frame through different techniques, such as using clips. Another technique to attach an auxiliary frame to a primary frame is by way of magnets. Examples of using magnets as an attachment technique can be found, for example, in U.S. Pat. No. 6,012,811, entitled, “EYEGLASS FRAMES WITH MAGNETS AT BRIDGES FOR ATTACHMENT.” 
     A number of embodiments have been described where one or more electrical components are at least partially embedded in a pair of glasses. In yet another embodiment, the one or more electrical components are at least partially embedded in an eye mask. 
       FIG. 18  shows one embodiment  925  where one or more electrical components are at least partially embedded in an eye mask  927 . The eye mask  927  includes a piece of fabric that is opaque so that when the mask is worn, the mask wraps around the eyes to block light from entering into the eyes of the user. 
     The embodiment  925  includes a wrapping mechanism to hold the fabric onto the head of a user so that when the mask is worn by the user, the mechanism allows the fabric to have a relatively tight and comfortable fit over the face of the user. In one approach the wrapping mechanism is achieved with the fabric in the shape of a band and having a certain degree of elasticity. When the mask is worn by the user, the elasticity of the fabric allows the mask to establish a relatively tight fit over the face of the user. In another example, the fabric is a long piece of material. The wrapping mechanism includes a clip or Velcro at the two ends of the piece of material to tie the two ends together. In another example, the wrapping mechanism includes two elastic pieces of elastic materials at the two ends of the fabric. To wear the mask, each elastic piece of material goes over one of the ears of the user so that the fabric establishes a relatively tight fit over the face of the user. In yet another embodiment, the mask  927  includes a notch  935  to accommodate the nose of the user. In another embodiment, there can be additional padding in the vicinity of the one or more electrical components so that if an electrical component is pressed against the user, the padding serves as a buffer or cushion. 
     In one embodiment, a speaker  929  can be at least partially embedded in the mask  927 , and can be positioned close to and facing one of the ears of the user. The speaker  929 , through an electrical connector, is electrically connected to a cable  931 . The cable  931  can also have a connector  933  at its distal end. The connector  933  can be plugged into another device, such as a MP3 player or a CD player. After putting on the mask, with the connector  933  plugged into the another device, the user would be able to hear, for example, audio sounds such as music. The eyemask  925  can be applied to different areas. For example, the user can be on a plane, and would like to rest. The user can put on the eyemask  925 , and plug the connector  933  into a media outlet at an armrest of her seat in the plane. Thus, the user can enjoy music while taking a rest. The embodiment  925  could also include a plurality of speakers, such as one for each of the user&#39;s ears. 
     In another embodiment, the eyemask  927  includes the speaker  929  and a battery that is electrically connected to the speaker  929 . The battery can be in a pocket on the eyemask and can be replaceable. The battery can also be a rechargeable battery, such as a lithium-ion battery, and there is a connector at least partially embedded in the eyemask. The connector can be used to recharge the battery. 
       FIG. 19  shows another embodiment  950  where one or more electrical components are at least partially embedded in a night cap  952 . In one embodiment, the cap  952  is at least partially made of fabric. In another embodiment, the cap  952  is entirely made of fabric. The cap includes a wrapping mechanism. When the cap is worn, the wrapping mechanism holds the cap onto the head of the user, and allows the cap to have a relatively tight and comfortable fit over the head of the user. Again the wrapping mechanism can be an elastic band at the base  963  of the cap  952 . Or, the wrapping mechanism can include clips or Velcro as previously described. 
     The cap can include at least one speaker  954 , which is at least partially embedded in the cap  952 . When the cap  952  is worn by a user, the speaker  954  is positioned close to and facing one of the ears of the user. The speaker  954  can, for example, be electrically connected through a connector to a device  962  in a pocket  960  on the cap  952 . The electrical connection can be through a cable  956  external to the cap  952 . The cable  956  also can have a connector  958  to be plugged into the device  962 . In another embodiment, the cable  956  is embedded in the cap. The device  962  can be an asset player, such as a MP3 player, with a battery. Through the connector  958 , audio signals from the device  962  can be received by the speaker  954  and heard by the user. There can be one or more additional pockets on the night cap for one or more additional electrical components. When worn, the night cap does not have to cover the eyes of the user. In yet another embodiment, when worn, the night cap further covers the eyes of the user, as shown in  FIG. 19 . In one embodiment, the embodiment  950  further includes padding in the vicinity of an electrical component to serve as a buffer or cushion between the user and the electrical component. 
     A number of embodiments have been described involving a speaker in an eyemask or a night cap. In one embodiment, the audio output from the speaker can serve to cancel the environmental sounds in the vicinity of the user. For example, if the user is on an airplane, the surrounding environmental sound has a relatively high level of white noise. This white noise can be detected by a pickup device and cancelled by noise cancellation circuitry provided within the eyemask or night cap. Namely, the audio output from the speaker serves to cancel the white noise of the user&#39;s environment. In another embodiment, the electrical component embedded or partially embedded is not a speaker, but can be a sensor, which can sense a physiological function of the user. 
       FIG. 20A  is a diagram illustrating a temple  1000  having a slot for receiving a removable electronic device  1002  according to one embodiment of the invention. In one example, the removable electronic device  1002  can be a memory storage device, sometimes referred to as a memory card. As shown in  FIG. 20A , the removable electronic device  1002  is inserted into the slot. Although the slot could be electrically non-functional, typically the slot provides an avenue for the removable electronic device  1002  to be physically and electrically connected to electrical circuitry within the temple  1000  or elsewhere within the eyeglass frame.  FIG. 20B  is a diagram illustrating the temple  1000  having a recessed lower portion  1004  according to another embodiment of the invention. The recessed lower portion  1004  facilitates the insertion and removal of the removable electronic device  1002 . In either embodiment, the removable electronic device can be manually inserted and removed or can use more complicated mechanical mechanisms to assist with the insertion and removal (e.g., spring-based push and release structure). 
       FIGS. 21A and 21B  are diagrams illustrating a pair of glasses  2100  having a camera  2101  coupled thereto, according to one embodiment. The camera includes an image sensor  2102  and a camera housing  2106  (also referred to as a camera support arm). In this embodiment, the camera  2101  is rotatably coupled to an exterior surface of a temple  2104  of the pair of glasses  2100 . The camera support arm  2106  is attached to the temple  2104 . The camera support arm  2106  can couple to the temple  2104  using a hinge  2108 . In one implementation, the hinge  2108  can use a spring or cam mechanism so that the camera support arm  2106  is held either against the temple  2104  when not in use or held in an open or extended position when in use.  FIG. 21A  illustrates one position of the camera support arm  2106  when the camera  2101  is not in use.  FIG. 21B  illustrates one position of the camera support arm  2106  when the camera  2101  is in use. The presence of the camera  2101  with the pair of eyeglasses  2100  enables a wearer of the pair of eyeglasses  2100  to take pictures of what the wearer is looking at. It should be noted that other supporting circuitry such as data storage for pictures, switches, battery, and electronics for the camera  2101  can be in the temple  2104 , in the camera support arm  2106 , elsewhere in the pair of glasses  2100 , or even tethered thereto. However, in one implementation, the camera  2101  is completely self-contained in the camera housing  2106 . In one embodiment, the hinge  2108  can also serve as a switch to turn the image sensor  2102  on or off. 
     In one implementation, to improve overall appearance of the pair of glasses  2100 , the temple  2100  can provide a recess for receiving the camera support arm  2106  when the camera is not being utilized. Such may improve the aesthetic appearance of the pair of glasses  2100 . 
     In another implementation, the pair of glasses  2100  can further provide a viewfinder. The viewfinder can assist the user in directing the image sensor  2102  towards whenever the user desired to photograph. The viewfinder can be a separate apparatus that is extended by user action or can be a viewfinder that is visually present or presented on one of the lenses. In one example, the viewfinder can be an extendable viewer through which the user can look through to determine the field of reference of the image sensor  2102 . The viewfinder can be extendible from either of the temples, such as in a telescoping, sliding or flipping action. Additionally, when the camera support arm  2106  is extended, a viewfinder can be automatically initiated. For example, indicators on one of the lens can be visually presented, such as through optical projection from one or more light sources. In another embodiment, the viewfinder can be always present, such as with indicators on one of the lens of the pair of glasses  2100 . The indicators can be a few faint dots to define an area (e.g., a square) on the lens. 
     In one embodiment, the camera support arm (camera housing)  2106  is removably coupled to the hinge  2108 . As such, the camera  2101  can be removed from or attached to the pair of glasses  2100 . Indeed, the camera support arm (camera housing)  2106  can be a camera body that houses electronics for the camera  2101 . In such case, the camera  2101  can operate as a camera apart from the pair of glasses  2100 . 
     In one implementation, the camera support arm  2106  has a connector and the hinge  2108  has a counterpart connector. In one example, the connectors are peripheral bus connectors, such as USB connectors. In such case, the camera support arm  2106  can be attached and removed from the pair of glasses  2100 . Such a connection via the connectors can be electrically functional or non-functional. If functional, electrical components in the pair of glasses  2100  can be electrically connected to electrical components in the camera  2101 . 
     Still further, in one embodiment, the connector at the end of the hinge  2108  enables connection of a variety of different peripheral devices to the pair of glasses  2100 . For example, the different peripheral devices (portable electronic devices) can be the camera, a memory card, or a media player. In one embodiment, electrical components integral with the pair of glasses  2100  can be shared by the different peripheral components. The hinge  2108  is not necessary in other embodiments, see  FIGS. 8F-8H , where a connector is attached or integral with a temple of a pair of glasses. If desired, the camera  2101  or other peripheral devices can include in its structure a hinge or other mechanism to permit positioning the camera or other peripheral devices. 
     In still another embodiment, an angled or hinged adapter can be inserted between a connector attached to the pair of glasses  2100  and a connector of the camera  2101  or other peripheral devices. The adapter can be electrically functional or non-functional. 
     In yet in another embodiment, a pair of glasses functioning as a headset with a speaker and a microphone further includes a camera.  FIG. 22  is a diagram of a pair of glasses  2200  having a camera according to one embodiment of the invention. The glasses  2200  include a temple  2205  that has a microphone  2204 , a speaker  2206  and a camera  2208  with a connector  2210 . The connector  2210  is for connecting, for example, to another electronic device that provides at least one of data or information transfer capabilities or a power source for the glasses. 
     In one embodiment, the camera  2208  is a digital camera with an on/off switch  2212 . For example, the camera  2208  is a CCD camera including a CCD controller coupled to a CCD chip to capture images, a CCD memory device and a lens. 
     In one embodiment, with the connector  2210  connected to another electronic device (e.g., a portable electronic device), when the switch  2212  is pushed on, the CCD chip takes a picture. The charges in the CCD chip are digitized and transmitted through the connector  2210  to the other electronic device, under the management of the controller. At least some of the charges can be temporarily stored in the CCD memory device, for example, to accommodate the differences in speed in taking pictures and sending the pictures to the portable device through the connector. In this embodiment, images can be stored at the other electronic device. In another embodiment, the glasses can include sufficient data storage capabilities to store the pictures, at least until transferred to another electronic device. 
     In one embodiment, the glasses do not offer focusing capability. The CCD chip can be located, for example, at the focal point of the lens. In another embodiment, there is an image distance control knob. For example, a mechanical lever can be pre-programmed or pre-set to move the lens to one or more different positions. In one implementation, there can be just two positions. One position can be for close-up shots and another for distance shots, such as close-up being about 2 ft from the lens and the distant being about 6 ft away; or close-up being about 8 inches away and distant being about 2 ft away. 
       FIG. 22  shows one embodiment regarding the location of the camera  2208  at the end of the temple or arm  2205  of the glasses  2200  next to the hinge. The lens of the camera faces forward. In this situation, what the user sees is substantially what the captured image would be. In other words, in a general sense, what the user sees through the glasses is what the user gets, without the need for an additional view finder. With such an embodiment, it is relatively easy for a user to take pictures, hands-free, without the need for an additional strap for holding the camera. 
     The connector  2210  at the end of the glasses  2200  can be, for example, a 4-terminal connector, one for ground, one for power and the other two for transmit and receive signals. In another embodiment, the connector  2210  can be a 3-terminal connector, with the power line and one of the signal lines sharing one terminal. 
     Regarding the embodiment shown in  FIG. 22 , the speaker  2206  can be in the glasses, with a tube  2216  and an ear bud  2218 , to help bring audio signals to the user. In one embodiment, the tube  2216  can be rotated at its end where it connects to the glasses. In another embodiment, the speaker  2206  can be provided at the ear bud  2218 . 
     In one embodiment, the CCD chip with the CCD memory device and the CCD controller are on the same integrated circuit. 
     The embodiment shown in  FIG. 22  also includes a microphone  2204 . In one embodiment, the CCD memory device also stores audio signals from the microphone  2204 . For example, the memory device stores a duration of time, such as the last 15 seconds, of audio signals. When the user takes a picture, a duration of time before taking the picture, such as the previous 15 seconds, audio signals can be coupled to the picture. Another duration of time after taking the picture, such as the next 10 seconds, of audio signals can also be coupled to the picture. In one embodiment, the audio picked up can include environmental sounds present at that time. The audio signals or the digitized version of the audio signals can also be transmitted to the other electronic device with the corresponding picture. In the future, if the user wants to view the picture, the audio signals can be played with the picture at the same time. As another example, the user can provide an auditory annotation to the pictures being taken. Here, the user can leave a specific audio message to be associated with the picture. For example, the user might take a picture of his childhood home and record an audio annotation, “This is where I grew up”. 
     In one embodiment, a pair of glasses functions as a headset with a speaker, a microphone and a camera. The pair of glasses can be coupled to another electronic device through a connector of the glasses. Additional electrical components, such as those in the other electronic device, like a portable device, for the glasses can be incorporated in the glasses. For example, the power source can also be in the glasses and the glasses do not have to include a connector. In one embodiment, the glasses include non-volatile memory to store at least a number of pictures. In another embodiment, the glasses further include a connector to receive a memory card, such as a flash memory device. The card can be a standard memory card with a USB connector. Pictures taken can be stored in the removable memory card. 
     In yet another embodiment for the glasses with a camera, the glasses do not include a speaker or a microphone. The glasses include a temple that has a CCD controller coupled to a CCD chip, a CCD memory device and a lens. The temple also includes an on/off switch with a connector. The connector is for connecting, for example, to a portable device that includes at least a power source for the camera. 
     In still another embodiment, an auditory feedback by a speaker is provided or coupled to a pair of glasses. For example, a clicking or “snapshot” sound can be output when a picture is taken (such as when a user initiates the picture taking). 
     Additional disclosure on camera in glasses can be found in U.S. Provisional Application No. 60/583,169, filed on Jun. 22, 2004, which is hereby incorporated by reference. 
     A number of electrical components have been described. They can be on circuit boards, which can be made of flexible materials. They can be on a substrate. They can also be integrated into one or more integrated circuits. 
       FIG. 23A  is a diagram of a pair of glasses (i.e., eyeglass frame)  2300  having a camera according to one embodiment of the invention. The eyeglass frame  2300  illustrated in  FIG. 23A  includes a lens holder  2302  holding a lens  2304  and a lens holder  2306  holding a lens  2308 . The eyeglass frame  2300  also includes temples  2309  and  2310 . In the embodiment shown in  FIG. 23A , the temple  2310  includes a camera  2312 , supporting electronics  2314  and a switch (e.g., button)  2316 . In one embodiment, the camera  2312  includes a CCD chip. The camera  2312  can also include a lens and buffer memory. In one embodiment, the electronics  2314  illustrated in  FIG. 23A  can be embedded within the temple  2310 . The electronics  2314  can include at least a microcontroller (e.g., an image processor), a memory, and a battery. These electronics  2314  can support the camera  2312 . The eyeglass frame  2300  can further include various other electrical components. For example, the eyeglass frame  2300  can further include one or more of: a microphone, an earphone, a removable memory, a display, a clock, and a Global Positioning System (GPS). These electrical components can be used in conjunction with the camera  2312  or separately from the camera  2312 . The button  2316  enables a wearer of the eyeglass frame  2300  to turn the camera  2312  on/off and/or to cause a picture to be taken (recorded). For example, by pushing the button  2316  for more than a few seconds, the camera will be turned off. However, by pushing and releasing the button  2316 , the camera takes a picture. 
     Still further, in the embodiment of the eyeglass frame  2300  shown in  FIG. 23A , the eyeglass frame  2300  further includes a view finder  2318  and an angled surface  2320 . Other embodiments of eyeglass frames need not include such features. Nevertheless, the view finder  2318  can assist a wearer (i.e., user) of the eyeglass frame  2300  in understanding the frame of the image (picture) being captured by the camera  2312 . In this example, the view finder  2318  is provided on the lens  2304  in a visible, yet non-distracting manner. As shown in  FIG. 23A , the view finder  2318  can be positioned such the wearer can direct the image (picture) to be captured. For example, the wearer would orient their head (using the view finder  2318 ) to direct the camera  2312  towards the desired subject. Also, the angled surface  2320  allows mounting the camera  2312  in an angled manner. As a result, the direction of the camera  2312  is not straight forward but out towards the side. This facilitates the wearer in directing the camera  2312  using a single eye via the lens  2304 , and more particularly via the view finder  2318  if provided. The outward angle from straight forward being utilized by the camera  2312  can vary with implementation. For example, the outward angle can be in the range of 10-70 degrees or more particularly in the range of 15-60 degrees, or more particularly in the range of 20-40 degrees from the perpendicular direction of the plane of a front surface of the eyeglass frame  2300 . In one embodiment, with the camera positioned at an angle, the lens holder  2302  would not block the field of view of the camera even with the camera being positioned at a distance behind the lens holder  2302 . 
     Although the camera  2312  is provided on the left side of the pair of glasses  2300  as shown in  FIG. 23A , it should be understood that the camera could alternatively or additionally be provided on the right side of the glasses. 
       FIG. 23B  is a diagram of a pair of glasses (i.e., eyeglass frame)  2300 ′ according to another embodiment. In this embodiment, the eyeglass frame  2300 ′ is similar to the eyeglass frame  2300  illustrated in  FIG. 23A . However, the eyeglass frame  2300 ′ further includes a connector  2322  and a memory card  2324 . More particularly, the temple  2310  includes a region  2326  larger than the temple region shown in  FIG. 23A . The larger or enlarged region can provide additional space for the connector  2322  and the memory card  2324 . The memory card  2324  can be operatively connected electrically to the electronics  2314  within the temple  2310  via the connector  2322 . The connector  2322  also can serve to provide a physical connection of the memory card  2324  to the eyeglass frame  2300 . In one embodiment, such physical connection is removable so that the memory card  2324  can be connected to or removed from the temple  2310 . Accordingly, the memory card  2324  can facilitate porting of data or information (e.g., pictures) from the eyeglass frame  2300 ′ to another electronic device (e.g., computer). As an example, the connector  2322  can be a USB connector or other peripheral type connector. 
     The eyeglass frame having a camera according to one embodiment of the invention can further include one or more sensors. For example, the one or more sensors can include one or more of a “being worn” sensor, a motion sensor, and a light sensor. These sensors can be used to influence operation of the camera provided with the eyeglass frame. For example, a “being worn” sensor can be used to determine whether the eyeglass frame is being worn by a user. If the eyeglass frame is not being worn, then the camera can be deactivated to prevent unnecessary battery consumption and/or to prevent pictures from being taken. As an example, if the camera is operated to automatically, periodically take a picture, then if the eyeglasses are not being worn, the automatic picture taking process could be stopped. In one embodiment, a motion sensor can be used in a variety of ways. A motion indication can indicate a rate of activity of the user. For example, the rate of activity could be used to avoid taking pictures during periods of high activity, such as rapid movements of the eyeglass frame (or the corresponding user), or to influence image processing, such as exposure rate. As another example, the rate of activity can be used to control the rate pictures are taken such as in the automatic picture taking example. In one embodiment, a light sensor can indicate the degree of light in the vicinity of the camera. The light indication can influence the image processing, such as exposure rate of the camera. 
     In one embodiment, in an automatic picture taking example, the location, time or device resources (e.g., available memory) can also be used to control the rate pictures are taken. Also, the ability of the eyeglass frame to know or acquire time and/or location information (such as the location of the eyeglass frame or the corresponding user) can enable pictures taken by the camera to be stored along with time and/or location indications. 
     The eyeglass frame having a camera according to one embodiment of the invention can further include a global positioning system (GPS). The information from the GPS can be used to alter configuration settings and/or influence operation of the camera. For example, the configuration settings can be different at night versus during daytime or can be different depending on time or location. As another example, the camera can take pictures depending on location. In one implementation, the camera can automatically take pictures dependent on a change in location. For example, after taking a picture, the camera can take a subsequent picture when the change in location exceeds a predetermined threshold. 
     In one embodiment, the camera utilized in the various embodiments is a digital camera, namely, a digital image capture device. The camera can be a still camera or a motion camera (i.e., video camera). The camera can be designed for manual focusing, auto-focusing, or predetermined fixed focusing. The camera can also support a wide angle or panoramic view. 
       FIG. 24  is a side view of a pair of eyeglasses (i.e., eyeglass frame)  2400  according to another embodiment of the invention. The eyeglasses  2400  include a lens holder  2402  for a lens  2404 . The lens holder  2402  is for the left side of the eyeglasses  2400 . A bridge  2406  couples the lens holder  2402  to another lens holder for the right side of the eyeglasses. In this embodiment, the lens  2404  and the lens holder  2402  extend substantially around the side and are sometimes referred to as “wrap-around” type frames. The eyeglasses  2400  include a temple having a forward temple portion  2408  and a rearward temple portion  2410 . Typically, the lens holder  2402 , the temple  2406 , the forward temple portion  2408  and the rearward temple portion  2410  are integrally formed as a single structure. The eyeglasses  2400  also support audio output to a wearer of the eyeglasses  2400 . To support audio, the eyeglasses  2400  include an ear bud  2412 , which serves as a speaker, and an extension arm  2414 . In this embodiment, the extension arm  2414  couples the ear bud  2412  to the forward temple portion  2408 . The extension arm  2414  can be pliable so that the wearer can adjust the position of the ear bud  2412 . In further support of audio, the eyeglasses  2400  couple to a cable  2416 . The cable  2416  provides audio signals to the ear bud  2412  via at least one electrical conductor extending through the cable  2416  and the extension arm  2414  to the ear bud  2412 . In one implementation, one end of the cable  2416  has a connector  2418  and the other end is integral with or connected to the forward temple portion  2408 . The connector  2418  can connect to a media output device, such as a portable media player (e.g., radio, MP3 player, CD player, etc.). In another implementation, the cable  2416  can have a connector, such as a plug, that connects to a jack  2420  embedded in the forward temple portion  2408 , thereby allowing the cable  2416  to detach from the eyeglasses  2400 . Alternatively, the cable  2416  can directly connect to the media output device without the use of the connector  2418 . Optionally, the eyeglasses  2400  can also support audio input by providing a microphone with the eyeglasses  2400 . In one embodiment, with a microphone, the eyeglasses  2400  serve as a headset for a phone. 
     Regardless of the electrical components being utilized with the eyeglass frames, it may be desirable for the eyeglass frames to be substantially balanced in weight. In the event that electrical components are attached and/or at least partially embedded in one of the temples of the eyeglass frame, the other of the temples can include other electrical components or even a counter weight so that the eyeglass frame can be substantially balanced. 
     A number of embodiments have been described regarding electrical components in a temple of a pair of glasses. All of the electronic components can be self-contained inside the temple of the glasses. The components can be coupled to a printed circuit board. In other embodiments, some of the components are embedded fully or partially in other areas of the glasses, such as the lens holders or the bridge of the glasses. Or, one or more electrical components can be in a shield of the glasses. In one embodiment, one embedded electrical component can include a circuit board. The circuit board can be a rigid or a flexible circuit board. In a number of embodiments, electrical components have been described to be fully or partially embedded in a temple of glasses, or in a temple arrangement. In other embodiments, the component(s) can be in other parts of the glasses, such as the lens holders, the nose pads, the bridges or the shields.
