Abstract: A server transmits an encoded game frame over a network to a respective client system as a set of packets. In response to transmitting the set of packets, the server determines a bandwidth estimate based on the size of the encoded game frame and the timing data associated with the transmitted set of packets. The server then compares the bandwidth estimate to a current video bitrate of the game stream being transmitted from the server to the respective client device. In response to the comparison indicating an underutilization of the network, the server increases the encoding bitrate. Further, in response to the comparison indication an overutilization of the network, the server decreases the encoding bitrate.

Abstract: A wireless vibrometer employs an antenna array to significantly boost the signal-to-noise ratio of faint received signals twin small objects vibrating at acoustic frequencies. This technique may be used to provide an improved physiological monitor (such as a pulse detector) or for long-range eavesdropping using the emitted power from a cell phone or the like.

Abstract: The inventors have recognized that in RF communication systems, by switching between transmit antennas of an RF transmitter on a sub-symbol basis (antenna index coding), and/or by adaptively determining how often antenna switching occurs (adaptive antenna hopping), an increased amount of data may be wirelessly transmitted to an RF receiver without significantly increasing energy consumption. The inventors have determined that in certain systems, such as ZigBee, data symbols consist of elementary waveform patterns, and that such waveform patterns for transmit antennas may be stored by an RF receiver for later determining transmit antennas for data symbols. The inventors have also determined that the invention may be applied in the frequency domain, such as to OFDM, by storing subcarrier waveform patterns for particular transmit antennas and later determining transmit antennas for subcarriers of data symbols.
