Abstract: An optical lens assembly with an electrically controlled, tunable optical lens with an attached aperture stop provides autofocus or similar functionalities in a camera with a wide field of view (FOV) (that is larger than 100 degrees in diagonal direction). The tunable optical lens is positioned between a first optical lens and a second optical lens in the optical lens assembly with the assembly including any number of negative or positive optical power lenses and/or other optical elements such as polarizers, quarter wave plates, optical filters, and similar ones.

Thus, spherical or aspherical reshaping of the tunable lens may be accomplished through the transparent piezoelectric layer.

Abstract: Video presence systems are described that detect an area of interest (e.g., facial region) within captured image data and analyze the area of interest using known color information of the content currently being presented by a display, along with measured ambient light color information from a color sensor, to determine whether the area of interest (e.g., face) is currently illuminated by the display or whether the AOI is not affected by the display and instead only illuminated by the ambient light. Upon determining that the display casts color shade on the AOI, the video presence system pre-processes the image data of the detected area of interest to correct the color back to skin color under ambient light prior to performing general white balance correction.

Abstract: An efficient trap avoidance and shared protection method in a survivable network with shared risk link groups. The invention includes a fast and efficient heuristic algorithm for avoiding traps, an algorithm, which may also be applied effectively to shared SRLG protection. Compared to other existing algorithms, the algorithm embodied in the present invention runs much faster, and yet falls into few traps, and achieves a much higher bandwidth efficiency. This technology can be applied to MPLS, ATM, SONET, WDM, and other high-speed survivable network designs.

Abstract: This invention broadly comprises a novel segment protection scheme (survivability framework) for a network, which we refer to as PROMISE (Protection using MultIple SEgments). It combines the best of existing link and path protection schemes (e.g., bandwidth efficiency and fast recovery). The PROMISE approach divides an active path or AP (along which a survivable connection is established) into several, possibly overlapping active segments or ASs, and then protects each AS with a detour called backup segment or BS (instead of protecting the AP as a whole as in path protection schemes). This facilitates the bandwidth sharing not only among the BSs for different APs, but also among those for the same AP. In addition, recovery time can be shortened due to the limited length of each AS and BS. This technology can be applied to MPLS, ATM, SONET, WDM and other high-speed link layers under the evolving G-MPLS framework.
