20090177467 | DETECTOR FOR USE IN VOICE COMMUNICATIONS SYSTEMS - One or more methods and systems of detecting or identifying one or more types of algorithms used in the encoding of a voice or speech waveform is presented. The system and method may be used as a testing tool to identify whether a voice data stream is encoded using a linear G.711, μ-law G.711, or A-law G.711 algorithm. The system and method are applied to a voice data stream to ensure that a codec with the appropriate algorithm is used to reproduce an audio waveform. | 07-09-2009 |
20100122109 | MIPS RECOVERY TECHNIQUE - 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. | 05-13-2010 |
20100278224 | WIFI INTERFACE TO DIALUP MODEM - 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. A representative embodiment permits a user of a conventional Internet web browser application to access a dialup information provider via a switched telephone network, using the wireless network. A terminal adapter comprising a wired network interface and a wireless network interface receives messaging containing dialing information from a user of a personal computer, via the wireless network. The terminal adapter establishes a dialup connection to the information provider, and exchanges information between the personal computer and the information provider via the wired and wireless interfaces. Information used for dialing may be contained within a universal resource locator received by the terminal adapter, or may be received as a result of user input on a webpage type user interface displayed by the browser application using information sent by the terminal adapter. | 11-04-2010 |
20100325302 | GENERIC ON-CHIP HOMING AND RESIDENT, REAL-TIME BIT EXACT TESTS - Details of media encoding and decoding devices which support generic homing sequences, and methods for operating such devices are disclosed. The use of generic homing sequences may permit an embodiment of the disclosed invention to support real-time, bit-exact testing of existing and future media encoding and decoding devices. An embodiment of the present invention may permit the initialization of encoding and decoding algorithms to a known state, enabling bit-exact testing of a large group of devices using these algorithms, including those whose specifications do not support such functionality. This capability may permit the full-speed, bit-exact, testing, of both locally and remotely situated media encoders and decoders. | 12-23-2010 |
