Abstract: Self-calibration of devices such as computer and graphics processors permits adjustment of processor clock rates, and access to normally unused processor capacity. Processor clock rates specified by device manufacturers are normally selected to insure operation across the entire manufacturer-specified range of operating temperatures and supply voltages. By limiting processor clock rates to nominal values, even when operating well within manufacturer-specified temperature and/or supply voltage limits, designers sacrifice processor capacity. By determining the upper limits of processor clock rates at which reliable operation can be realized, and adjusting processor clock rates to match those speeds, a representative embodiment of the present invention permits device users to gain additional, previously inaccessible processing capacity.

Abstract: Systems and methods that enable high quality audio teleconferencing are disclosed. In one embodiment of the present invention, a signal processor receives signals from a spatially dispersed set of directional microphones, processing the microphone signals and the far-end received audio into a signal for transmission to a far-end party. The processing may comprise the use of one or more algorithms that reduce conference room noise and may selectively increase participant audio levels by processing the microphone signals using beamforming techniques. An embodiment of the present invention may also comprise one or more omni-directional microphones that may be used in cooperation with the directional microphones to adjust for background noise, acoustic echo, and the existence of side conversations.

A memory (44) stores the compressed data and stores operating data and operating code for a plurality of decompression algorithms requiring different amounts of memory for the operating data and operating code and requiring different amounts of memory to store compressed data corresponding to a predetermined amount of uncompressed data. A processor (42) is arranged to select one of the decompression algorithms, to allocate an amount of the memory for storing compressed data and operating data and operating code depending on the decompression algorithm selected and to decode the compressed data stored in the allocated amount of memory.

Abstract: A device and method support dialup modem access over a wireless local area and/or personal area network such as, for example, an IEEE 802.11 a/b/g/n and/or IEEE 802.15.3a network.

Abstract: A system and a method for wireless playing media files utilizing a central server, in which a database of media files is stored, is described. The system includes a base-station connected to the server, a set of media clients that can be placed in different locations within the service area of the base-stations. The media clients can wirelessly connect to the server via the base-station to access the media files database and download media files, decode and play the media files. The media clients can be connected to devices capable of outputting the media files decoded and played by the media clients. The media clients can be also incorporated into mobile devices and cars, such that a user can download media files from the server and be able to display them at a location remote from the server and the service area of the base-station.
