In a method and apparatus for generating a power supply voltage, an integrated circuit including an adaptive power supply voltage circuit is provided where a target signal is generated representing an ideal or approximated ideal performance characteristic of a functional block operating with the power supply voltage. A generated functional block test signal is generated representing the performance characteristic of the functional block under these conditions. The adaptive power supply voltage circuit compares the target signal with the generated functional block test signal and adjusts the power supply voltage continuously until the target signal and generated functional block test signal are substantially equal. When the target signal and generated functional block test signal are substantially equal, the power supply voltage is locked for subsequent use. By optimizing the power supply voltage, minimal power dissipation is provided.

A method of deinterlacing interlaced fields of video for display in a progressive display device includes providing at least one candidate motion vector per scan line and determining, at least one final motion vector per scan line of interlaced video, for use in deinterlacing the interlaced fields, by iteratively changing the at least one candidate motion vector per scan line based on pixel intensities from each of a plurality of same polarity fields at locations along a single dimension.
摘要:
A wireless sensor network for monitoring one or more selected environmental characteristics. Multiple wireless signal transceivers, disposed in respective portions of a selected environment, respond to one or more wireless beacon signals by selectively collecting, processing and storing data corresponding to one or more characteristics of such portions of the selected environment, and by selectively transmitting respective wireless response signals containing selected portions of such data. Alternatively, multiple wireless signal transceivers, disposed in respective sub-networks in portions of a selected environment, collect and convey data corresponding to one or more characteristics of such selected environment portions.

A double-sampled pipeline analog-to-digital conversion (ADC) system and method in which latching of the intrastage digital quantization signals occurs approximately midway the leading and trailing edges of the clock signals.
摘要:
The present disclosure relates to a differential signaling circuit including differential signaling circuitry having at least one output and one input, that can operate in multiple mode of operations while using a single, low voltage supply source. Two or more switches are included and configured to selectively couple a supply voltage to the output dependent on a mode of operation of the differential signaling circuitry. The circuit also includes a switch control biasing circuit operatively coupled to at least one of the switches and to the output of the differential signaling circuitry. The switch control biasing circuit provides a switch control biasing voltage to control a state of the switch based on a voltage level of the output. Further, a bulk biasing circuit is included and operatively coupled to the switch. The bulk biasing circuit selectively provides a bulk biasing voltage to the switch based on the voltage level of the output.

An apparatus and method for controlling signal gain and reference black level of a video signal. Magnitudes of signal gain and reference voltage for a subject video signal are determined by a common digital control signal, while the reference voltage determines the reference black level.
摘要:
Apparatus and method for providing for packet data communication between a single-input-single-output (SISO) transceiver and a single-input-multiple-output/multiple-input-single-output (SIMO/MISO) transceiver. Receive channel coefficients representing relative strengths of individual signals received via multiple spatially diverse antenna elements and corresponding to a wireless data signal originating from a particular SISO radio frequency (RF) transceiver are used to provide substantially complementary transmit channel coefficients for use in producing outgoing RF signals to be transmitted via the same antenna elements for reception by such particular SISO RF transceiver.
摘要:
A telescoping slide rail assembly including interconnected mounting, intermediate and stationary slide rails movable relative to one another to extend and retract the mounting and intermediate slide rails relative to the stationary slide rail between fully extended and retracted positions. The intermediate slide rail includes a latching mechanism for interconnecting the intermediate and stationary slide rails in the fully extended position and the mounting slide rail includes an alignment device to maintain orientation between the mounting slide rail and the intermediate slide rail.
