FIELD OF THE INVENTION
The present invention generally relates to the field of computer systems and more particularly related to computer systems having video and audio applications.
BACKGROUND
Desktop computers are normally heavy comparing to notebook (also called laptop or mobile) computers. A desktop computer typically includes a separate display unit or monitor connected to a system or base unit via a display cable. Notebook computers on the other hand are typically light and compact and are becoming more popular in recent years. One advantage of notebook computers is their ease of mobility. The lighter weight and the compact size together with the long battery life have made the use of notebook computers more commonplace. Although the light weight and the dependency on battery life mean that the notebook computers may not be equipped with as many features as their larger desktop siblings, the processing power of the notebook computers is becoming increasingly faster.
As the processing power of the desktop and the notebook computers increases, more advanced applications may become available. These more advanced applications may utilize different components, interfaces, etc. to improve user experience and productivity. Some examples of applications may include video conferencing applications, video phone applications, voice over Internet Protocol (VoIP) applications, image and voice recognition applications, etc. To support these applications, some of the issues that may need to be addressed by computer manufacturers include thermal management, battery life, form factor, etc.

The sound capturing devices 215 and 220 may be deactivated when the top panel 230 is partially or wholly retracted relative to the display housing 200.
Retractable and Extendable Edge Panels
For one embodiment, the display housing 200 may include a side insert or panel located generally near a left edge of the display housing 200 and is referred to as a left panel 205. The display housing 200 may also include another side insert or panel located generally near a right edge of the display housing 200 and is referred to as a right panel 210, as illustrated in FIG. 2A. For one embodiment, the left panel 205 and the right panel 210 may be retracted relative to the display housing 200 and may be extended relative to the display housing 200 along the direction shown by the arrow next to the left panel 205 and next to the right panel 210, respectively. For example, the display housing 200 may include a slot along its left edge and a slot along its right edge to accommodate the left panel 205 and the right panel 210, respectively. For one embodiment, the left panel 205 and the right panel 210 may be retracted into and extended from the display housing 200 in between the displacement between the front and the back of the display housing 200, as shown in FIG. 2B.
Edge Panels with Sound Capturing Devices
For one embodiment, each of the left panel 205 and the right panel 210 may include one or more sound capturing device (not shown). These sound capturing devices may be microphones or any other types of devices that enable capturing sound based on the position of the left panel 205 and the right panel 210, respectively. For one embodiment, the sound capturing devices located in the left panel 205 and in the right panel 210 may be activated when the left panel 205 or the right panel 210 is partially or wholly extended from the display housing 200. The sound capturing devices located in the left panel 205 or in the right panel 210 may be deactivated when the left panel 205 or the right panel 210 is partially or wholly retracted into the display housing 200.
The multiple sound capturing devices in the top panel 215, left panel 205 and right panel 210 form an array of sound capturing devices and may enable picking up sound from various angles in front of the display housing 200. The array of sound capturing devices may also enable approximating a location of a sound source and to control the image capturing device 225 to point in the direction of the sound source. The array of sound capturing devices may enable a user to give voice commands. By spreading the sound capturing devices at different places on the display housing 200, acoustic clarity may be attained. The combination of the image capturing device 225 and the array of sound capturing devices may enable a user to have hands free interactions with the computer system associated with the display housing 200.
Synchronous Movement
For one embodiment, the top panel 230, the left panel 205 and the right panel 210 may be individually deployed or extended from the display housing 200. For example, a separate push-pull mechanism (not shown) may be used with each of the panels 230, 205, 210. Similarly, they may also be individually retracted. For one embodiment, the top panel 230, the left panel 205 and the right panel 210 may be deployed in a synchronous manner. For example, using a one touch operation, all three panels may be retracted into or extended from the display housing 200 at about the same time.
FIGS. 3A and 3B illustrate one example of an arrangement that may be used to enable synchronous movement of the panels, in accordance with one embodiment. In this example, a bellcrank 330 may be used in conjunction with a push-pull mechanism (not shown) associated with top panel 315. For example, when all three panels 315, 305, and 315 are retracted into the display housing 320, applying pressure to the push-pull mechanism may cause the top panel 315 to rise or extend from the top edge of the display housing 320. As the top panel 315 rises, it rotates the bellcrank 330 counter-clockwise, thus extending the left panel 305 and the right panel 315 from the display housing 320, as illustrated in FIG. 3A. Applying pressure to the push-pull mechanism again may cause the top panel 315 to withdraw or retract into (in the direction shown by the arrows) the display housing 320. As the top panel 315 withdraws, it rotates the bellcrank 330 clockwise, thus retracting the panels 305 and 315 into the display housing 320, as illustrated in FIG. 3B.
FIGS. 4A and 4B illustrate another example of an arrangement that may be used to enable synchronous movement of the panels, in accordance with one embodiment. In this example, a cam 430 may be used in conjunction with a push-pull mechanism (not shown). The push-pull mechanism may be associated with top panel 415. Alternatively, the push-pull mechanism may be associated with the left panel 405 or the right panel 410. For example, when all three panels 415, 405, and 410 are retracted into the display housing 420, applying pressure to the push-pull element may cause the top panel 415 to rise or extend from the top edge of the display housing 420. As the top panel 415 rises, it rotates the cam 430 anti-clockwise, thus extending the panels 405 and 415 from the display housing 420, as illustrated in FIG. 4A. Applying pressure to the push-pull element again may cause the top panel 415 to withdraw or retract into (in the direction shown by the arrows) the display housing 420. As the top panel 415 withdraws, it rotates the cam 430 clockwise, thus retracting the panels 405 and 415 into the display housing 420, as illustrated in FIG. 4B.
FIGS. 5A and 5B illustrate another example of an arrangement that may be used to enable synchronous movement of the panels, in accordance with one embodiment. In this example, a switch 530 may be used in conjunction with multiple solenoids 501, 502, 503, each connected to a top panel 515, a left panel 505 and a right panel 510, respectively. The switch 530 may need to be a flip, a slider, etc. so that a user can select, for example, “extend” or “retract” to extend or retract all of the panels relative to the display housing 520, as illustrated.
Although the examples provided above refer to a top panel, and left panel and a right panel, embodiments of the present invention may include additional panels coupled to the displaying housing and having one or more image capturing devices and one or more sound capturing devices. For one embodiment, as illustrated in an example in FIGS. 6A and 6B, the panels 605, 610, and 615 may rotate clockwise or counter-clockwise relative to the display housing 200 using a wheel mechanism 630. For another embodiment, as illustrated in an example in FIG. 7, the panels 705, 710, and 715 may, instead of retracting into the display housing may fold backward or forward along the edges of the display housing using hinge mechanisms (not shown). Although not shown, the panels 705, 710, and 715 may also fold backward and forward relative to the back side of the display housing.
Although the present invention has been described with reference to specific exemplary embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader spirit and scope of the invention as set forth in the claims. For example, other mechanisms may be used to raise or to lower the panels as described above. For another example, the size of the panels described above may vary as long as they are able to accommodate an image capturing device and or one or more sound capturing devices. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
