摘要： A power management technique for a network including a plurality of computing devices. The power management technique includes identifying an order in which one or more devices of the plurality of computing devices can transmit data within the prescribed time period. In one aspect, the number of wakeups are reduced for the computing devices within the network by increasing a number of adjacent channel time allocation periods within a prescribed time period that share a common computing device. In one aspect, the network can be based on Time Division Multiple Access (TDMA).

摘要： A scalable audio codec processes, quantizes and encodes audio signals into an embedded audio bitstream of bit-planes each having a data unit. The data unit has a beginning refinement bits partition, a second significance bits partition, a third sign boundary mark bits partition, and a fourth sign bits partition. The second and fourth partitions form a boundary for the third partition. The quantizing uses a variable length coding algorithm. The third partition is an invalid codeword for a predetermined encoding method being used to encode. The codec uses a decoder to decode the embedded audio bitstream of bit-planes using Reversible exponential Golomb (Exp-Golomb) codes in a Reversible Variable Length Code (RVLC) algorithm to produce quantized data of weighted subbands. An inverse quantizer dequantizes the quantized data into audio signals.
