     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention generally pertains to a laptop computer and more particularly to a camera latch that is incorporated into a laptop computer. 
     2. Description of the Related Art 
     Laptop computers generally consist of a lid for housing a display screen such as an LCD and a base for housing various operational components such as a processor, a hard drive, a disk drive, a modem, a battery, etc. The base also typically carries several input devices including a keyboard, a track pad (or track stick), and various buttons. In most cases, the lid is hinged to the base so as to move the lid between a closed position, placing the lid against the base, and an open position, exposing the display screen and the input devices to the user. 
     Most portable computers require that the lid be securely attached to the base for transportation. As such, a locking mechanism is generally provided to secure the lid to the base when the lid is in the closed position. The locking mechanism typically includes a hook, which extends from the lid and which is configured for lockably engaging the base when the lid is in the closed position. The locking mechanism may also include a slide knob for slidably releasing the hook from the base so as to place the lid in the open position. 
     Various peripheral input output devices may be electrically connected to the laptop computer. The peripheral I/O devices may include memory, disk drives, keyboards, monitors, mice, printers, scanners, speakers and digital cameras. In most cases, the peripheral I/O devices are connected to laptop computer through wired connections using a serial, USB, or Firewire interface. In other cases, the peripheral I/O devices (as for example keyboards and mice) are connected to the laptop through wireless connections such as radio or Bluetooth. 
     Digital cameras, in particular, have become increasingly popular input devices. The digital camera records images in digital form and feeds the images to the laptop computer. The images may be downloaded into the laptop computer as they are recorded or they may be stored in the digital camera for downloading at a later time. Once in the computer, the images can be edited, copied, emailed, broadcasted, etc. Some examples of digital cameras include webcams, point and click cameras and camcorders. In all of these examples, the digital camera includes a sensor that converts light into electrical charges. The image sensor employed by most digital cameras is a charge coupled device (CCD), although complimentary metal oxide semiconductor (CMOS) may also be used. 
     Digital cameras and more particularly webcams, whose output is primarily available for viewing over the Internet, may also be configured for video conferencing. Video conferencing generally refers to a live connection between two or more participants in separate locations for the purpose of audio and video communication. At its simplest, videoconferencing provides transmission of images and text between two locations. At its most sophisticated, it provides transmission of full motion video images and high quality audio between two or more locations. 
     Although current laptop designs work well, in many instances it would be desirable to provide laptops with improved and/or additional functionality while maintaining aesthetics and keeping with the current trend of smaller and more powerful laptops.

     DETAILED DESCRIPTION OF THE INVENTION 
     Embodiments of the invention are discussed below with reference to  FIGS. 1-11 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. 
       FIG. 1  is a perspective diagram of a portable computer  100 , in accordance with one embodiment of the invention. The portable computer  100  generally includes a base  102  and a lid  104 . The base  102  is configured to enclose various integrated circuit chips and other circuitry that provide computing operations for the portable computer  100 . By way of example, the integrated circuit chips and other circuitry may include a microprocessor, Read-Only Memory (ROM), Random-Access Memory (RAM), a disk drive, a battery, and various input/output support devices. The base  102  is also arranged to hold a plurality of input devices such as a keyboard  106 , a track pad  108  and button(s)  110 . 
     The lid  104  is pivotally mounted to the base  102  via a hinge mechanism  112 . As such, the lid  104  may rotate to various positions between an open position ( FIG. 1A ) and a closed position ( FIG. 1B ) relative to the base  102 . The lid  104  generally contains a liquid crystal display (LCD)  114  that is used to display the graphical user interface (including perhaps a pointer or cursor) as well as other information to the user. The LCD display  114  is generally surrounded at a peripheral region by a bezel  116  that serves to support the LCD display  114  in its assembled position within the lid  104 . 
     The hinge mechanism  112  generally allows the lid  104  to pivot relative to the base  102  so as to adjust the orientation of the lid  104  relative to the base  102 . For example, the lid  104  may rotate between an open position and a closed position. In general, the open position corresponds to a lid orientation that allows a user to use the portable computer, i.e., the LCD display  114  and input devices  106 - 110  are visible and accessible to a user, and the closed position corresponds to a lid orientation that allows a user to store or transport the portable computer, i.e., the base and lid are substantially flush with one another such that the LCD  114  and the input devices  106 - 110  are no longer visible or accessible to a user. 
     In most cases, the hinge mechanism  112  is configured to hold the lid  104  in its desired position (e.g., open, partially open or closed). The hinge mechanism  112  may for example include a brake configured for exerting a frictional force on the lid  104  so as to maintain the position of the lid  104  when the lid  104  is moved to the desired position. By way of example, a cam may be used to create the frictional force. In general, the cam moves between an engagement position, preventing the lid from slipping out of position, and a release position, allowing the lid to freely rotate around the pivot. Other braking features may also be used as for example, friction washers, gears etc. 
     A locking mechanism  120  is also provided for securing the lid  104  to the base  102  when the lid  104  is in the closed position. The locking mechanism  120  generally includes a latch  122  that is received by a latch receiving area  124  of the base  102  when the lid  104  is placed in the closed position. The latch  122  and the latch receiving area  124  are cooperatively positioned so that when the lid  104  is closed, the two elements engage with one another thus securing the lid  104  to the base  102 . As shown, the latch  122  protrudes from a top portion of the bezel  116  (above the LCD  114 ) and the latch receiving area  124  is located in the front portion of the base  102  (in front of the track pad  108 ). 
     The latch  122  and latch receiving area  124  can be widely varied. For example, the latch  122  may be fixed to the bezel  116  or it may be movably coupled thereto so that it can be more easily positioned next to the latch receiving area  124 . The latch  122  may for example be pivotally coupled to the bezel  116  so that it can rotate into engagement with the latch receiving area  124 . Furthermore, the latch receiving area  124  may correspond to the outer front surface of the base  102  or it may correspond to a cut out  126  in the base  102 . The cut out  126  is generally configured to receive the latch  122  therein. The cut out  126  may be used to place the back surface of the latch flush with the outer front surface of the base  102  when the lid  104  is in the closed position. By way of example, the cut out  126  may be a channel that runs through the entire front surface of the base  102  or it may be a recess that only runs partially through the front surface of the base  102 . In either case, the cutout  126  is set to receive the latch  122  when the lid  104  is closed. The shape of the cut out  126  generally corresponds to the shape of the latch  122 . This is typically done to eliminate voids or substantial breaks between the edges the latch  122  and cut out  126  when the latch  122  is mated within the cut out  126 . The shapes may for example include ovals, rectangles, squares, circles, etc or other complex shapes. 
     In one embodiment, the latch  122  and latch receiving area  124  include locking features  128 A an  128 B that are cooperatively positioned so that when the latch  122  is positioned next to the latch receiving area  124 , the locking features  128  lockably engage with one another thus securing the latch  122  to the base  102 . The locking features  128  may be widely varied, and may for example include catches, plungers, hooks, flanges, slots, guides, and the like. In order to allow the lid  104  to be opened, the latch  122  or latch receiving area  126  may also include a latch release mechanism  130  for releasing the locking features  128  from their locking engagement. The latch release mechanism  130  generally includes an actuator for disengaging the locking features  128  and a biaser for providing a spring action that pushes the latch  122  away from the latch receiving area  124  when released. By way of example, the actuator may correspond to a knob, button, slider or switch that can be easily manipulated by a user, and the biaser may be a spring, flexure or deformable member 
     In another embodiment, the latch  122  is configured to carry a data capture device  132  for capturing or collecting data. By integrating a data capture device into the latch, the space taken up by the laptop is preserved, i.e., adding a data capture device does not compromise the x, y and z dimensions of the laptop. The data capture device  132  may be configured to capture audio data, image data, and/or the like. In the case of audio data, the data capture device  132  may include a microphone and in the case of image data the data capture device  132  may include a camera. The camera may be configured to produce a single image, images at intervals or a live video stream. In some cases, the data capture device  132  combines a camera and one or more microphones into a single unit. In other cases, the data capture device  132  only includes one of these components. By way of example, the camera may include image sensors such as charge coupled device (CCD) or complimentary oxide semiconductor (CMOS) and optics such as lenses, splitters, filters and the like. In addition, the microphone may include diaphragms, amplifiers, digital signal processors (DSP), etc. 
     To elaborate, the data capture device  132  may be mounted to the surface of the latch  122  or it may be embedded or enclosed inside the latch  122 . When embedded or enclosed, the latch  122  typically includes an opening so as not to impede the line of sight of the data capture device  132 . 
     In order to make the data capture device  132  more user friendly, the latch  122  may be configured to move relative to the lid  104  rather than being fixed thereto. By way of example, the latch  122  may pivot, swivel and/or translate relative to the lid  104  so that the position of the data capture device  132  can be adjusted. The pivot action, (as shown by arrow  134 ), allows the latch  122  to rotate forwards and backwards, the swivel action (as shown by arrow  136 ) allows the latch  122  to rotate side to side, and the translating action (as shown by arrows  138  and  140 ) allows the latch  122  to slide up and down or side to side, respectively. These types of motions may be particularly useful when using a data capture device such as a camera during video conferencing. The motions can be formed from various mechanism including but not limited to one or more pin joints, slider joints, ball and socket joints, flexure joints and the like. The motions can also be formed from a combination of joints as for example a pivot/translating joint, pivot/flexure joint, pivot/ball and socket joint, translating/flexure joint, and the like. The motions can also be formed from various memory materials that can be bent, twisted or otherwise deformed in order to place the latch  122  in the desired position. 
     As shown in  FIG. 1C , the latch  122  may be detachable from the lid  104 . This may allow a user to place the data capture device  132  in more advantageous position for capturing data. By way of example, this may allow a user to use a latch camera as a point and click camera or a latch microphone as a speaker&#39;s or singer&#39;s microphone. If detachable, the lid  104  may include a docking station or latch bay  142  for receiving the latch  122 . The docking station  142  may be movable relative to the lid  104  or the removable latch  122  when attached may be movable relative to the docking station  142  in order to provide the pivot, swivel and/or translation. A locking mechanism  144  may be provided between the latch  122  and the docking station  142  in order to lock and release the latch  122  to and from the lid  104 . When detached, the data capture device  132  contained within the latch  122  may be connected to the lid  104  through wires or cables  146  that provide an electrical connection to the internal components of the portable computer  100 . Alternatively, the latch  122  may include a memory module, battery and associated electronics thereby making the latch a fully operable stand alone device as for example a point and click camera. The latch may additionally include a small LCD so that the user can view the images stored in the memory module. In cases such as these, the latch  122  may include a connector that operatively couples with a connector located in the docking station  142 . In a similar vein, the latch  122  and docking station  142  may include wireless transceivers based on FM, RF, Bluetooth, 802.11, UWB (ultra wide band), IR, magnetic link (induction) and/or the like. 
     In another embodiment, the latch  122  is configured to carry one or more indicators  148  for alerting a user to a particular status or a change in status of the portable computer  100 . By integrating an indicator into the latch, the other surfaces of the laptop can be preserved, i.e., adding an indicator does not compromise the surfaces of the base or lid. For example, latch  122  may include a power/sleep indicator that alerts a user as to when the computer  100  is on/off or in a sleep mode. Sleep indicators are typically illuminated when the computer is on, and not illuminated when the computer is off. Furthermore, sleep indicators may turn on and off or cycle with increasing or decreasing intensity (ebb) when in sleep mode. The indicators  148  can be placed at any location on the latch  122 . Some positions may be more desirable than others. For example, the sleep indicator may be placed on the backside of the latch  122  as shown so that it can be seen when the lid  104  is closed and the latch  122  is engaged with the latch receiving area  124  of the base  102 . 
     Although not shown, the indicators  148  generally include a light source such as an LED. The LED may be placed in an opening in the latch  122  or they may be hidden within the latch  122 . If the later, the latch housing  123  may include a clear or translucent insert that is located in front of the LED. The LED is configured to illuminate the insert. The insert may include a light diffuser in order to hide the internal components of the latch while still allowing light to pass therethrough. Furthermore, the insert may be any shape. By way of example, the insert may be a logo such as a computer manufacturer logo, or some other character or shape. In cases where there is limited space, the indicator  148  may include light guiding or piping materials that allow the light source to be placed at various locations within the latch  122 . In some cases, the insert may serve as both the indicator window and a light guiding medium. Alternatively, the latch housing  123  may be formed from a clear or translucent material thereby eliminating the insert. The illuminable area of the latch housing  123  may constitute a small portion of the latch housing  123  or the entire latch housing  123  may be illuminable. Furthermore, a mask may be used to produce shapes like the insert when utilizing a translucent latch housing. 
     It is contemplated that the portable computer  100  can be lap top computer such as an IBM compatible computer or an Apple compatible computer. By way of example, the Apple compatible computer may include different models such as the iBook, or Titanium models, which are manufactured by Apple Computer, Inc. of Cupertino, Calif. 
       FIGS. 2A-2D  are diagrams of laptop computer  150 , in accordance with one embodiment of the present invention. By way of example, the laptop computer  150  may generally correspond to the portable computer  100  shown and described in  FIG. 1 .  FIG. 2A  is a front elevation view of the laptop computer  150  in an open position.  FIG. 2B  is a side elevation view, in cross section (taken substantially along line A-A) of the laptop computer  150  in the open position.  FIG. 2C  is a front elevation view of the laptop computer  150  in a closed position.  FIG. 2D  is a side elevation view, in cross section (taken substantially along line B-B) of the laptop computer  150  in the closed position. 
     As shown, the laptop computer  150  includes a base  152  and a lid  154  that is pivotable relative to the base  152  via a hinge mechanism  156 . The hinge mechanism  156  allows the lid  154  to pivot about axis  158  through various angles a relative to the base  152 . For example, the lid  154  may be pivoted between the open position (as shown in  FIGS. 2A and 2B ) and the closed position (as shown in  FIGS. 2C and 2D ). Although not shown, the hinge mechanism  156  may include a braking feature that holds the lid  154  in its various positions between the open and closed position. The braking feature essentially allows a user to position the lid  154  at any angle during use. In most cases, there is a maximum angle, which corresponds to the fully open position. The maximum angle is typically somewhere between about 90 degrees to about 180 degrees. The minimum angle is typically set at 0 degrees, i.e., at the interface between the lid  154  and base  152  when the lid  154  is in the closed position. 
     The lid  154  generally includes an LCD panel  160  that is surrounded at its periphery by a bezel  162 . The lid  154  also includes a latch  164  that is attached to the bezel  162 . The latch  164  is configured to mate with a cut out  166  in the base  152  in order to secure the lid  154  to the base  152  and to produce an aesthetic looking enclosure when the lid  154  is placed in the closed position. The latch  164  is generally dimensioned for receipt within the cut out  166  so that it resides within the cut out  166  when the lid  154  is closed. In most cases, the back surface  168  of the latch  164  is made flush with the outer surface  170  of the base  152  in order to produce a substantially continuous outer surface when the latch  164  is positioned within the cut out  166 . 
     In order to lock the latch  164  to the base  152  and thus the lid  154  to the base  152  when the lid  154  is in the closed position, the latch  164  includes a latch-side locking feature  172  that is configured to lockably engage a base-side locking feature  174 . By way of example, the base-side locking feature  174  may be a plunger and the latch-side locking feature  172  may be a hook that is capable of capturing the plunger. The position of the locking features  172  and  174  may be widely varied, i.e., they may be positioned at any of the mating surfaces between the latch  164  and the cut out  166 . In the illustrated embodiment, the latch side locking feature  172  is positioned on a front surface  176  of the latch  164 , and the base side locking feature  174  is positioned on a front surface  178  of the base inside the cut out  166 . In order to release the locking features  172  and  174  as for example the plunger from the hook, the latch  164  also includes a slider  180 . The slider  180  is slidably coupled to the latch housing and is configured to disengage the locking features  172  and  174  when translated from a first position to a second position. 
     The latch  164  is configured to carry a camera  184 . The camera  184  may for example correspond to a digital camera such as a point and click camera, camcorder, web cam, videoconferencing camera or the like. The camera is disposed inside a latch housing  186 , and is configured to capture image data through an opening in the latch housing  186 . By way of example, the camera  184  may include a CMOS image sensor chip and a lens assembly. The camera  184  may be attached to a portion of the latch housing  186  and/or a printed circuit board located within the latch housing  186 . In fact, the PCB may be part of the camera  184 . In most cases, the camera  184  is electrically coupled to control electronics in the base  152  through wires that extend from the PCB, through the bezel  162  of the lid  154 , through the hinge mechanism  156  and into the base  152 . 
     As shown, the latch  164  is pivotable relative to the bezel  162  via a second hinge mechanism  188 . The second hinge mechanism  188  allows the latch  164  to pivot about axis  190  through various angles β relative to the lid  154 . For example, the latch  164  may be pivoted between a first position (as shown in  FIGS. 2A and 2B ) and a second position (as shown in  FIGS. 2C and 2D ). By providing a pivoting action, the position of the latch  164  may be adjusted to place the latch  164  within the cut out  166  when the lid  154  is closed or being closed and to place the latch  166  in multiple camera viewing positions when the lid  154  is opened. For example, during a videoconference, the user can adjust the latch position to place the line of sight  192  of the camera  184  on the user. 
     In most cases, there is a maximum and minimum angle β. The maximum angle β is typically about 180 degrees so that the latch  164  lines up with the rest of the lid  154  when the lid is opened. The minimum angle β is typically set at 90 degrees so that the latch  164  can be positioned within the cut out  166  adjacent the outer surface of the base  178  and not closer than that to eliminate impinging the latch  164  when the lid  154  is closed. It should be noted, however, that these maximums and minimums are not a limitation. For example, the maximum β may be closer to 360 degree in order to allow the latch  164  to pivot around the top surface of the lid  154  so that the camera  184  can be used on the other side of the lid  154 . In cases such as this, the control electronics may be configured to reverse the captured image(s) so that the image(s) is right side up when viewed as for example on the LCD  160 . 
     Although not shown, the laptop computer  150  may include a positioning device for controlling the rotation of the latch  164  about the axis  190 . The positioning device may be widely varied. For example, like the first hinge mechanism, the second hinge mechanism may include a braking feature that holds the latch  164  in its various positions between the first and second position. The braking feature essentially allows a user to position the lid at any angle during use. The user simply grasps and pivots the latch  164  to the desired position. Once positioned, the braking feature holds the latch  164  in the desired position. The braking feature may for example include friction washers, detents, gears and/or the like. 
     Alternatively, an electronic actuator for rotating the latch  164  about the axis  190  may be used. For example, the actuator may correspond to a motor such as a servo motor. The actuator may be housed in the latch housing  186 , the hinge mechanism  188 , the bezel  162 , the hinge mechanism  156  and even within the base  152 . The actuator may be directly coupled to the latch  164  or it may be indirectly coupled to the latch through various motion transformers such as gears, cables, belts and the like. Furthermore, the actuator may be controlled directly through an electronic switch or button dedicated to rotating the latch  164  or indirectly through software and the user interface of the laptop computer  150 . For example, the user may press the arrow keys to move the latch  164  to the desired position. 
     In one embodiment, the latch  164  is automatically positioned in a home position when the lid  154  is opened. The home position may be some preset position set by the manufacturer or a position previously set by the user. The home position may place the latch  164  in a position that sets the appropriate camera viewing angle on the user or some other angle as for example an angle that places the latch  164  in line with the lid  154 . By way of example, the home position may be between about 0 and 360 degrees, more particularly between about 90 and 270 degrees, and even more particularly about 180 degrees. Even though a home position may be provided, it should be noted that in most cases the latch may be moved from the home position to other positions once the lid is opened. This gives the user the ability to fine tune the position of the latch  164  and thus the camera during use. 
     In addition, the latch  164  may also be automatically positioned in a lock position when the lid  154  is closed. The lock position is typically the position that places the latch  164  within the cut out  166  adjacent the outer surface  178  of the base  152  so that the locking features  172  and  174  can engage with one another. That is, the lock position places the front side of the latch  164  next to the front surface  178  within the cut out  166 . In some cases, the timing may set up so that as the lid  154  finally closes, the latch  164  finally rotates into the cut out  166 . That is, as the lid  154  is finally closing the latch  164  assumes the locked position. 
     In most cases, the positioning of the latch is configured to adjust or change in accordance with the positioning of the lid. For example, as the angle α increases in order to open the lid  154 , the angle β increases in order to place the latch  164  in the home position and as the angle α decreases in order to close the lid  154 , the angle decreases β in order to place the latch  164  in the locked position. In one implementation of this embodiment, the positioning device includes a latch tilting mechanism. The latch tilting mechanism is configured to convert the rotation of the lid  154  about the axis  158  to rotation of the latch  164  about the axis  190 . That is, when the lid  154  is opened or closed, the latch tilting mechanism causes the latch  164  to pivot to the home or locked positions. The latch tilting mechanism may include a belt that rotatably couples an axle of the first hinge mechanism  156  to an axle of the second hinge mechanism  188 . In most cases, the belt travels through the bezel  162  from the axle of the first hinge mechanism  156  to an axle of the second hinge mechanism  188 . When the lid  154  is opened thus increasing α, the rotation of the axle causes the belt to move in the clockwise direction. The clockwise motion of the belt in turn causes the axle of the second hinge mechanism  188  to move in the clockwise direction. Because the axle is mounted to the latch  164 , the clockwise motion of the axle causes the latch  164  to rotate about its axis in a clockwise manner thus increasing β. This clockwise motion cause the latch  164  to pivot from the locked to home position. When the lid  154  is closed, the reverse is true, i.e., everything moves in a counterclockwise motion. Although a belt is described in should be noted that this is not a limitation and that the latch tilting mechanism may include gears, cams, and the like. 
     The latch  164  is also configured to carry a symbol illumination system. The symbol illumination system operates to illuminate a symbol  196  on an illuminable portion of the latch housing  186  using light provided by a light source. The symbol  196  may be widely varied. For example, the symbol  196  may be one or more characters, letters or numbers; a simple shape such a circle, rectangle, square, triangle, etc., or it may be a more complex shape such as, icon, logo, etc. In one configuration, the symbol  196  is an Apple corresponding to the Apple logo used by Apple Computer of Cupertino, Calif. The location of the symbol  196  can also be widely varied. For example, it can be positioned on any surface of the latch  164 . In the illustrated embodiment, the symbol  196  is placed on the backside  168  of the latch  164  so that it can be seen by the user when the latch  164  is positioned within the cut out  166 . 
     The symbol illumination system may be widely varied. By way of example, the light source may be one or more light emitting diodes (LED), LCD panels, light emitting semiconductor dies, lasers, incandescent light bulbs, fluorescent light bulbs, neon tubes, and the like that produce white or colored light. The light source may even correspond to the LCD  160  contained within the lid  154 . For example, the backlighting from the LCD panel may be used to illuminate the illuminable portion. Furthermore, the illuminable portion may be a clear or translucent portion of the latch housing  186  or it may be provided by a separate piece of clear or translucent material that is inserted and affixed within an opening in the (translucent or non-translucent) housing. By way of example, the illuminable portion may be formed from glass or plastic materials such as polycarbonate, acrylic and the like. The illuminable portion may include a light diffusing means or color filtering means located either internal or external to the illuminable portion. As should be appreciated, the light diffusing means scatters the transmitted light to produce a characteristic glow that emanates from the outer surface of the illuminable portion, and the color filtering means allows certain colors to pass through thereby causing the illumination portion to exude a certain color. 
     The light source is typically placed inside the latch housing  186  behind the illuminable portion so that the illuminable portion can be illuminated thereby creating the symbol (e.g., lit up). Generally speaking, a symbol image is formed at the outer surface of the illuminable portion, and may even glow, when light is made incident on the inner surface of illuminable portion via the light source. In cases where the light source cannot be placed behind the illuminable portion, a light directing element such as a light pipe or light guide can be used to direct the light from the light source to the illuminable portion. The light directing element may be a separate component or it may be integral with the illuminable portion. The symbol illumination system may additionally include a masking element for helping produce the desired symbol shape. The masking element generally includes an opening corresponding to the symbol image to be illuminated. 
     The light source of the symbol illumination system is typically controlled by the control electronics stored in the base of the laptop  150  so as to produce a symbol light effect having specific characteristics or attributes. For example, the light may be used to exhibit a behavior that reflects the desires or moods of the user, that reflects inputs or outputs for the laptop computer  150 , or that reacts to tasks or events associated with operation of the laptop computer  150 . In most cases, illumination processing includes monitoring events associated with the laptop computer  150  (e.g., software or hardware) and controlling the light source based on the monitored events so as to indicate a status corresponding to the monitored event. The events being monitored are generally identified by an operating system or a microprocessor utilized within the laptop computer  150 . The events can take many forms such as operating system events or microprocessor events. By way of example, the events may relate to signals, conditions or status of the laptop computer  150  and/or to any devices or systems attached thereto (e.g., i/o devices, internet, etc.). The light source may be controlled in a manner that produces different symbol light effects for different events. For example, the light source may be configured to blink, ebb or produce different colors depending on the events that occurred. The light source may produce a red blinking light when a first event has been implemented, and solid blue light when a second event has been implemented. 
     The illumination characteristics and their associated with specific events may be stored in a database. Illumination characteristics generally refer to how a light source is illuminated to produce a visual effect (e.g., which lights are operated, how long the light sources are operated, what color the light source output, etc.). The illumination characteristics stored in the database may be accessed by a user through a light control menu, which may be viewed on the LCD as part of a GUI interface. The light control menu may serve as a control panel for reviewing and/or customizing the illumination characteristics, i.e., the user may quickly and conveniently review the illumination characteristics and make changes thereto. Once the user saves the changes, the modified illumination characteristics will be employed to handle future illumination processing. 
     Referring to  FIGS. 3-7  a latch assembly  200  will be described in accordance with one embodiment of the present invention. The latch assembly  200  includes a latch  202  that is pivotally coupled to a bezel  204 . As shown, the latch  202  includes a latch housing  206  that is positioned within a recess  208  in the bezel  204 . The recess  208  and latch housing  206  are dimension to allow the latch  206  to pivot within the recess  208 . The latch housing  206  includes an axle  210  fixed thereto. The axle  210  may be a separate component or it may be integral with the latch housing  206 . When a separate piece, the axle  210  may be attached using any suitable attachment means, including press fitting, screws, bolts, adhesives, etc. In one example, the axle  210  is press fit into a through hole in the latch housing  206 . 
     As shown in  FIG. 3 , the axle  210  is received by a pair of bushings  212  located on opposing sides of the latch housing  206 . The opposing ends of the axle  210  extend through through-holes in the bezel  204  and are supported by bushings  212  contained within the space provided between a display  214  and the bezel  204 . The bushings  212  typically include through holes  216  for rotatably receiving the ends of the axle  210 . The bushings  212  may be separate components or they may be integrally formed with the bezel  204 . If separate, they may be attached using any suitable attachment means, including press fitting, snaps, screws, bolts, adhesives, etc. Because of this configuration, the latch  202  is configured to pivot relative to the bezel  204 . 
     As shown in  FIGS. 3 ,  4  and  7 , the latch housing  206  is configured to contain several components including a camera module  220 , a locking mechanism  222 , and a symbol illumination system  224 . The camera module  220  includes at least a CMOS image sensor chip  226 , a lens assembly  228  and a printed circuit board  230 . The CMOS image sensor chip  226  and lens assembly  228  are both mechanically and electrically coupled to the PCB  230 . The PCB  230  is structurally attached to an interior portion of the latch housing  206  as for example using screws. The printed circuit board  230  is electrically coupled to control electronics through flex wires  232  that extend from the PCB  230 , through an opening in the latch axle  210 , through the bezel  204 . In laptop computers, the flex wires may additionally travel though a hinge mechanism and into the base. The position of the lens assembly  228  inside the latch housing preferable places the outer lens  234  of the lens assembly  228  adjacent an opening  236  in the latch housing  206 . The outer lens  234  may be recessed behind, flush with, or extend outside the latch housing  206  via the opening  236 . In the illustrated embodiment, the outer lens  234  is substantially flush with the outer surface of the latch housing  206  so that it sits within the opening, but not past it. This is generally done to both protect the outer lens and other components that it may interfere with it if it extended out of the latch housing  206 . 
     The symbol illumination system  224  includes an insert  240  and one or more LEDs  242 . The one or more LEDs  242  are both mechanically and electrically coupled to the printed circuit board  232  of the camera module  220 . The insert  240  is positioned within an opening  244  in the latch housing  206 . By way of example, the insert  240  may be press fit into the opening  244 . The insert  240  is formed from a translucent material. The translucency of the insert  240  is configured to allow the passage of light therethrough while preventing the user from clearly seeing or distinguishing objects through it as for example the LEDs  242  or the printed circuit board  232 . That is, the insert  240  transmits light while causing sufficient diffusion to prevent perception of distinct objects located behind it. The insert  240  may, for example, include a light diffusing means located either internal or external to the insert  240 . In this embodiment, the LED(s)  242  are side firing LEDs, i.e., the light produced therefrom is made incident on the side surface of the insert  240 . Any number of side-firing LEDs  242  may be placed around the perimeter of the insert  240 . The number of LEDs chosen preferably produces enough illumination to emit a characteristic glow that emanates equally from the outer surface of the insert  240 . In one configuration, the symbol illumination system  224  include red, blue, green and white LEDs that work together to produce the different colors of the color spectrum (e.g., mixing). This particular arrangement allows a laptop to change the color of the insert  240  according to specific tasks being performed in the laptop computer. 
     The locking mechanism  222  is not shown in great detail in  FIGS. 3-7 . These figures, however, do show a slit  250  in the latch housing  206 . The slit  250  is configured to receive a plunger  252  located on the base  254  when the latch  202  is placed in the closed or locked position as shown in the previous figures. That is, when the lid is closed and the latch  202  is positioned within a cut out  256  in the base  254 , the plunger  252  may be inserted into the slit  250  so that it can interact with a locking feature contained in the latch housing  206 . These figures also show a slide switch  258  that is used by the locking mechanism  222  to disengage the plunger  252  from the locking feature located behind the slit  250 . The slide switch  258  is slidably coupled to the latch housing  206 . For example, the slide switch  258  may include a rail that is retained within a channel in the latch housing  206 . In most cases, the slider switch is flush with the outer surface of latch housing in order to preserve a continuous look on the latch. Furthermore, the slider switch may include tactile bumps or knurls to help a user manipulate it. 
     Referring to  FIGS. 8A-8D , the locking mechanism  222  will be described in accordance with one embodiment of the present invention. As described above, the latch mechanism includes a slit  250  disposed in the latch housing  206 , and a slider switch  258  slidably coupled to the latch housing  206 . The slit  250  is cooperatively positioned with the plunger  252  and is dimensioned to receive the plunger  252  therethrough when the latch  202  is placed within the cutout  256  of the base  254 . The plunger  252  generally has a length that allows it to extend through the slit  250  to engage a spring element  260  and hook  262  located within the latch housing  206 . 
     The spring element  260  is cooperatively positioned with the plunger  252 , i.e., the central axis of the plunger  252  is substantially aligned with the central axis of the spring element  260 . The spring element  260  is configured to provide a spring resistance to the plunger  252  when the plunger  252  is inserted into the slit  250 . That is, when the latch  202  is pushed towards the base  254  using force F, the plunger  252  engages the spring element  260  and the force F works against the spring force of the spring element  260  until the latch  202  is placed in its desired position relative to the base  254 . The spring element  260  can be widely varied. For example, it may correspond to a flexure, a cushion or deformable member, a spring, and the like. In the illustrated embodiment, the spring element  260  is a tension spring that is retained on a post  264  that protrudes out of the interior surface of the latch housing  206 . When the latch  202  is closed, the spring element  260  in the form of a tension spring is compressed between the plunger  252  and the latch housing  206 . 
     The hook  262  is positioned in the same plane as the plunger  252  and is arranged for lockably receiving the plunger  252  when the plunger  252  is inserted into the slit  250 . The hook  262  is configured to rotate between a plunger receiving position for capturing the plunger  252  (as shown in  FIG. 8A ), and a plunger releasing position for releasing the plunger  252  (as shown in  FIG. 8D ). This is generally accomplished via a pivot pin that passes through the hook  262  and which is seated in the latch housing  206 . As should be appreciated, when the hook  262  is placed in the latch receiving position, the hook  262  captures the plunger  252  thereby securing the latch  202  to the base  254 . Conversely, when the hook  262  is placed in the latch releasing position, the plunger  252  is released from the hook  262 , and the latch  202  is left unsecured relative to the base  254 . Once unsecured, the both the lid and latch can be tilted as described above. Although not a requirement, the entire hook  262  is located inside the latch housing  206  at all times (e.g. both positions) to eliminate unsightly and harmful protrusions emanating from the latch  202 . 
     A spring element  268  is used to continuously exert a biasing force on the hook  262  so as to place the hook  262  in the plunger receiving position. The spring element  268  causes the hook  262  to rotate about the pivot axis until it reaches a stop surface  270  that determines the latch receiving position. The stop surface may be widely varied. For example, it may be a portion of the latch housing  206  or the slider switch  258 . In the illustrated embodiment, the stop surface  270  is formed by a flange  272  of the slider switch  258 . In this manner, the spring element  268  also exerts a biasing force on the slider switch  258  thereby placing the slider switch  258  in its first position against an abutment stop located on the latch housing  206 . 
     Because of space limitations, the spring element  268  generally corresponds to a torsion spring. The torsion spring has one end connected to the latch housing  206  and another end connected to the hook  262 . As such, the torsion spring exerts a force on the hook  262  relative to the latch housing  206 . It should be noted that the spring element  268  is not limited to torsion springs that other types of spring elements may be used. By way of example, compression and tension type springs may be used. Furthermore, deformable members or flexures may also be used. In fact, in some cases, the hook may be a flexure. 
     The slider switch  258  is configured to free the hook  262  from the plunger  252 . The slider switch  258  allows a user to move the hook  262  from the plunger receiving position to the plunger releasing position using a simple translating motion. This is generally accomplished with the flange  272  that extends out of the slider switch  258  and that engages one end of the hook  262  thereby causing the hook  262  to rotate about its axis when the slider switch  258  translates from a first position to a second position. The slider switch  258  is generally biased in the first position via a spring force. The spring force may be provided by a third spring element or the second spring element  268  associated with the hook  262 . 
     The operation of the locking mechanism  222  will now be described. In order to lock the latch  202  to the base  254 , the latch  202  is pushed against the base  254  by a force F provided by a users hand or finger. As the latch  202  nears the base  254 , the plunger  252  travels through the slit  250  and engages the spring element  260  contained within the latch housing  206 . Because the spring element  260  is a tension spring, the tapered tip  274  of the plunger  252  nestles into the opening in the tension spring upon engagement. Once engaged, the force F works against the spring force in order to further advance the plunger  252 . When the plunger  252  reaches the hook  262 , the tapered tip  274  of the plunger  252  pushes against the tapered surface  276  of the hook  262  (cam action) thereby causing the hook  262  to rotate about its axis against the spring force provided by the second spring element  268 . When the tapered tip  274  of the plunger  252  passes the tapered surface  276  of the hook  262 , the hook  262  collapses back towards the plunger  252  via the spring force provided by the second spring element  268  thereby capturing the tip  274  of the plunger  252  within the catch of the hook  276 . At this point the latch  202  is locked to the base  254 . 
     In order to unlock the latch  202  from the base  254 , the slider switch  258  is translated relative to the latch housing  206  by a force F 2  provided by a users finger or hand. As the slider switch  258  translates from the first position to the second position, the flange  272  of the slider switch  258  pushes against the hook  262  thereby causing the hook  262  to rotate about its axis against the spring force provided by the second spring element  268 . When the hook  262  reaches the plunger releasing position, the plunger  252  is no longer captured by the hook  262  and the first spring element  260  provides a spring force against the plunger  251  that pushes the latch  202  away from the base  254 . As the latch  202  moves away form the base  254 , the plunger  252  exits the slit  250  thereby releasing the latch  202  from the base  254 . 
       FIGS. 9A and 9B  are simplified side views of a laptop computer  300 , in accordance with one embodiment of the present invention. The laptop computer  300  includes a base  302  and a lid  304  that is pivotable coupled to the base  302  via a lid axle  306 . The lid axle  306 , which is attached to the lid  304  may for example be supported by bushings that are attached to the base  302 . The lid  304  is positionable between an open position (as shown in  FIG. 9B ) and closed position (as shown in  FIG. 9A ). The closed position is generally set by the interface between the base  302  and the lid  304 , i.e., the position that places the lid  304  adjacent the base  302  as shown in  FIG. 9A . The open position is generally some angle α that allows a user to view a LCD panel  308  disposed inside the lid  304 . The angle α may be widely varied. In the illustrated embodiment, the closed position corresponds to a position that places the lid  304  substantially 0 degrees relative to the base  302  as shown in  FIG. 9A , and the open position corresponds to a position that places the lid  304  substantially 90 degrees relative to the base  302  as shown in  FIG. 9B . Although there is a designated open position, it should be noted that the open position may be adjusted to other positions during use. For example, some users may prefer to place the lid  304  at an angle greater than 90 degrees for better viewing, especially when the laptop computer  300  sits low compared to the user. 
     The lid  304  includes a camera latch  310  that is pivotally coupled to the lid  304  via latch axle  312 . The latch axle  312 , which is attached to the latch  310  may for example be supported by bushings that are attached to the lid  304 . The latch  310  is positionable between a home position (as shown in  FIG. 9B ) and locked position (as shown in  FIG. 9A ). The locked position is generally set by the interface between the camera latch  310  and the base  302 , i.e., the position that places the camera latch  310  adjacent the base  302  as shown in  FIG. 9A . The home position is generally some angle β that places the line of sight of a camera  314  of the camera latch  310  on the user. The angle β may be widely varied. In the illustrated embodiment, the locked position corresponds to a position that places the camera latch  310  substantially 90 degrees relative to the lid  304  as shown in  FIG. 9A , and the home position corresponds to a position that places the camera latch  310  substantially 180 degrees relative to the lid  304  as shown in  FIG. 9B . Although there is a designated home position, it should be noted that the position of the camera latch  310  may be adjusted from the home position to other positions during use. For example, tall users may prefer to place the camera latch  310  at an angle greater than 180 degrees while short users may prefer to place the camera latch  310  at an angle less than 180 degrees. 
     The laptop computer  300  also includes a latch tilting mechanism  316 . The latch tilting mechanism  316  is configured to automatically place the camera latch  310  in the locked position when the lid  304  is placed in the closed position, and to automatically place the camera latch  310  in the home position when the lid  304  is placed in the open position. The latch tilting mechanism  316  includes a latch belt  318 . The latch belt  318  is operatively coupled to the both the lid axle  306  and the latch axle  312 . The latch belt  318  extends through the lid  304  between the lid housing  320  and the flat panel  308  contained therein. Rollers  322  may be provided to maintain the belt position between the lid housing  320  and the flat panel display  308 . Alternatively, the belt  318  may rub against the surface of the flat panel  308  instead of using rollers  322 . 
     As shown, the belt  318  is draped around the latch axle  312  and one end of the belt  318  is attached to the lid axle  306  and the other end of the belt  318  is attached to a tension spring  324  that is fixed to the lid housing  320 . The tension spring  324  keeps the belt  318  under constant tension. The tension spring picks up any slack in the belt  318  thereby ensuring contact between the belt  318  and the latch axle  312 . Alternatively, the tension spring may be replaced by a belt capable of stretching, i.e., the tension force is provided by the flexing of the belt. When the lid axle  306  is rotated from the closed to open position, the belt  318  is unrolled from the lid axle  306  and when the lid axle  306  is rotated from the open to closed position, the belt  318  is rolled up onto the lid axle  306 . During both unrolling and rolling, the belt  318  moves over the latch axle  312  thereby causing the latch axle  312  to rotate about its axis. During unrolling, the latch axle  312  rotates in a first direction thereby causing the camera latch  310  to tilt to the home position. During rolling, the latch axle  312  rotates in a second direction thereby causing the camera latch  310  to tilt to the locked position. 
     The diameters of the axles  306  and  312  may be adjusted to effect the rotation of the latch  310  relative to the rotation of the lid  304 . If the latch axle  312  and the lid axle  306  have the same diameter, the latch axle  312  will have the same amount of rotation as the lid axle  306 . By way of example, if the lid  304  is rotated 90 degrees relative to the base  302  then the latch  310  will be rotated 90 degrees relative to the lid  304 . Alternatively, if the latch axle  312  has a greater diameter than the lid axle  306 , the latch axle  312  will have less rotation as the lid axle  306 . By way of example, if the lid  304  is rotated 90 degrees relative to the base  302  then the latch  310  will be rotated less than 90 degrees relative to the lid  304 . In addition, if the latch axle  312  has a smaller diameter than the lid axle  306 , then latch axle  312  will have more rotation than the lid axle. By way of example, if the lid  304  is rotated 90 degrees relative to the base  302  then the latch  310  will be rotated more than 90 degrees relative to the lid  302 . 
     Referring to  FIGS. 10A and 10B , the latch tilting mechanism  316  will be described in greater detail.  FIG. 10A  is a diagram of the camera latch portion of the camera tilt mechanism  316 .  FIG. 10B  is a diagram of the lid portion of the camera tilt mechanism  316 . As shown, a first end of the belt  318  is attached to the flat tension spring  324  that in turn is attached to the back of the lid housing  320 , and a second end of the belt  318  is attached to the lid axle  306 . Furthermore, both the latch axle  312  and the belt  318  (in the region of the latch axle  312 ) have teeth  330  separated by notches  332 . The teeth  330  are configured to engage one another thereby causing the latch axle  312  to rotate about its axis when the belt  318  is rolled or unrolled relative to the lid axle  306 . In essence, the teeth  330  of the belt  318  mate with the teeth  330  on the latch axle  312  in order to drive the positioning of the latch axle  312 . When the lid axle rotates, the teeth located on the belt engage the corresponding teeth located on the latch axle. As the lid axle further rotates, each tooth engages another tooth thereby causing the latch axle and thus the latch to rotate about its axis. 
     Because of the tension spring  324 , the camera latch  310  can be tilted away from the home position set by the mated teeth by asserting enough force to advance the latch axle  312  to the next notch position. This is accomplished without causing any rolling or unrolling of the belt  318 , i.e., the position of the belt  318  stays stationary. The user simply pushes or pulls on the latch  310 . When the pulling or pushing force is great enough, the latch axle  312  is caused it to slip relative to the belt  318  thereby causing the next tooth on the latch axle  312  to engage the next notch on the belt  318 , i.e., the pulling or pushing force overcomes the tension force and any forces found between the mated teeth. In most cases, the slipping teeth create a click that gives the user the ability to feel when the camera latch  310  has moved to the next position. That is, the teeth serve as detents that provide a tactile way for the user to know when the latch camera  310  has reached a certain position. The number of latch positions generally corresponds to the number and dimensions of the teeth and notches. It is generally believed that more closely packed teeth/notches produces greater resolution. That is, the more closely packed teeth/notches, the smaller the incremental changes in distance moved by the latch axle and thus the camera latch. As should be appreciated, if there are N equidistance teeth/notch positions, discrete tilt angles of 360/N are possible. 
       FIG. 11  is a block diagram of a computer system  350 , in accordance with one embodiment of the present invention. The computer system  350  may for example correspond to a laptop computer such as any of those previously described. As shown, the computer system  350  includes a processor  356  configured to execute instructions and to carry out operations associated with the computer system  350 . For example, using instructions retrieved for example from memory, the processor  356  may control the reception and manipulation of input and output data between components of the computing system  350 . The processor  356  can be a single-chip processor or can be implemented with multiple components. 
     In most cases, the processor  356  together with an operating system operates to execute computer code and produce and use data. The computer code and data may reside within a program storage block  358  that is operatively coupled to the processor  356 . Program storage block  358  generally provides a place to hold data that is being used by the computer system  350 . By way of example, the program storage block may include Read-Only Memory (ROM)  360 , Random-Access Memory (RAM)  362 , hard disk drive  364  and/or the like. The computer code and data could also reside on a removable storage medium  366  and loaded or installed onto the computer system  350  when needed. Removable storage mediums include, for example, CD-ROM, DVD, PC-CARD, floppy disk, magnetic tape, and a network component. 
     The computer system  350  also includes a display device  368  that is operatively coupled to the processor  356 . The display device  368  is configured to display a graphical user interface (GUI) including perhaps a pointer or cursor as well as other information to the user. By way of example, the display device  368  may be a monochrome display, color graphics adapter (CGA) display, enhanced graphics adapter (EGA) display, variable-graphics-array (VGA) display, super VGA display, liquid crystal display (e.g., active matrix, passive matrix and the like), cathode ray tube (CRT), plasma displays and the like. 
     The computer system  350  also includes input/output (I/O) circuitry  370  that is operatively coupled to the processor  356 . The I/O circuitry  370  includes one or more controllers that may be integrated with the processor  356  or that may be separate components. The I/O circuitry  370  is generally configured to control interactions with one or more I/O devices  372  that can be coupled to the computer system  350 . By way of example, the I/O devices  372  may be internal or peripheral devices such as memory, disk drives, keyboards, mice, track pads, printers, scanners, speakers, video cameras, music players and the like. The I/O devices  372  may also be network-related devices such as network cards or modems. As should be appreciated, each of these devices may include a separate microcontroller for processing data at the device. 
     The I/O circuitry  370  generally operates by exchanging data between the computer system  350  and the I/O devices  372  that desire to communicate with the computer system  350 . In some cases, the I/O devices  372  may be connected to the I/O circuitry  370  through wired connections. When the I/O devices  372  are integrated into a single unit as for example a base of a laptop computer, the devices  372  are typically hard wired (unless they can be removably detached). When the I/O devices  372  are stand alone devices, the I/O devices  372  are typically connected through cables and connectors such as USB or Firewire. The I/O circuitry  370  may additionally include one or more media bays (expansion bays) capable of receiving media bay devices (expansion bay devices) to provide greater resources to the computer system. The media bays are accessible from external to the computer system so that media bay devices can be easily be inserted into the media bays or removed from the media bays. The removability of the media bay devices allows a few media bays to support a variety of different types of devices in a flexible manner. Alternatively, the I/O devices may be connected to the I/O circuitry  370  through wireless connections. By way of example, the data link may correspond to PS/2, USB, IR, RF, Bluetooth or the like. 
     In the illustrated embodiment, the I/O devices  372  include at least a keyboard  374 , a tracking device  376 , a disk drive  378 , a camera module  380  and a symbol illuminator  382 . The keyboard  374  is configured to deliver input commands and other instructions to the computer system  350 . The tracking device  376  is configured to deliver movement commands, i.e., the tracking device may be used to move a cursor or pointer or to implement a scrolling function on the display screen. The tracking device  376  may take the form of a mouse, a track ball, a touch pad, a stylus, a tablet and the like. The disk drive  378 , which facilitates transporting such data to other computer systems, is configured to store various types of data. The camera module  380  is configured to record and store images in digital form, and to feed these images to the processor  356 . Furthermore, the symbol illuminator  382  is configured to produce light in a controlled manner via one or more light sources. The light sources may for example be operatively coupled to the processor  356 . The light may be used to indicate a status of the computer system  350 . 
     While this invention has been described in terms of several preferred embodiments, there are alterations, permutations, and equivalents, which fall within the scope of this invention. For example, although the invention is primarily directed at a camera latch for a laptop computer, it should be noted that concepts disclosed herein may also be applied to other electronic devices, including but not limited to PDAs, music players, mobile phones and the like or I/O devices such as monitors, televisions and the like. It should also be noted that there are many alternative ways of implementing the methods and apparatuses of the present invention. For example, although the locking mechanism was described as including both a hidden locking feature (hook) and an exposed locking feature (plunger), it should be noted that in some cases the plunger may be hidden. As should be appreciated, plungers may be unsightly and potentially dangerous. A protruding plunger may result in the plunger being accidentally sheared off when it comes into contact with some other object. Also, if the plunger is accidentally slammed on a finger, or if the plunger hooks on clothing, it can cause injury or damage, leaving a negative impression on the user. By way of example, the hidden plunger may be extracted from the base using magnetic locking system as described in U.S. Pat. No. 6,659,516. Furthermore, in some cases, it may be desirable to reverse the automatic positioning of the latch relative to the base once the latch is placed in the home position and the lid is opened in order to ensure that the line of sight of the camera is directed at the user. For example, as the angle α increases, the angle β decreases and as the angle α decreases, the angle increases β increases in order to keep the line of sight directed at the user. It is therefore intended that the following appended claims be interpreted as including all such alterations and permutations.
