Title: Methods and systems for rate control within an encoding device
Inventor: WALKER KENT
IPC: H04N7/26
Filed: 2007-01-31
Abstract: This disclosure describes techniques for adjusting encoding variables of an encoding device. In response to a request to resize a segment of data, an encoding module adjusts at least one encoding variable used to encode one or more subsequent segments of data such that the subsequent segments of data are encoded at a bit rate that is different than the bit rate at which the subsequent segments of data would have been encoded had there been no request to resize. At some point, the encoding module re adjusts the encoding variables used to encode the segments of data such that the subsequent segments of data are encoded to achieve a desired encoding result. For example, the encoding module may re adjust the encoding variables after a period of time or may incrementally adjust the encoding variables until the encoding variables result in achieving the desired encoding result.

Title: High efficiency load insensitive power amplifier
Inventor: CHANG SHIAW W
IPC: H03F3/68
Filed: 2007-03-09
Abstract: An advanced balanced RF power amplifier circuit is provided. The RF power amplifier has a pair of RF amplification paths constructed to efficiently operate in a high-power mode. When instructed to operate in a low-power mode, one of the amplification paths is deactivated, and optionally, an impedance device is also set to operate at a low-power impedance value. With only one path operating in low-power mode, the network RF topology has changed from the topology of the high-power mode. This new topology provides increased impedance on the active RF amplification path as compared to when both RF amplification paths were active. This increased impedance causes the RF power amplifier to operate more efficiently in its low-power mode. Depending on the specific application and target performance, the impedance may be sufficiently increased simply by deactivating one of the RF amplification paths, and in other cases it may be desirable to switch an active or passive impedance device to operate at a low-power impedance. The impedance device enables further adjustment and tuning of the impedance in the low-power topology. ® KIPO & WIPO 2009
