20090115384 | Distributed Power Management - Apparatuses, methods, and systems for effective power management distribution are provided. In an embodiment, a system for providing power to a circuit block comprises a power management unit (PMU) configured on a first substrate and an integrated circuit (IC) configured on a second substrate. The PMU includes a first regulator configured to step down an input voltage and output a first regulated voltage. The IC includes the circuit block and a second regulator configured to receive the first regulated voltage and output a second regulated voltage. The second power regulated voltage provides power to the circuit block. The first regulator is more efficient than the second regulator. | 05-07-2009 |
20090174816 | Method And System For Detection Of Video Connections - Aspects of a method and system for detection of video connections are provided. In this regard, a pulse of current may be applied to a video interface and a voltage differential resulting from the applied current pulse may be measured to determine whether the video interface is connected to a video device. The current pulse may be a Hsync pulse of a video signal which may occur during a vertical blanking time of the video signal. A voltage differential resulting from each of a plurality of Hsync pulses occurring over one or more frames of said video signals may be measured. The current pulse may be a pulse in a pulse train. A voltage differential resulting from each of a plurality of pulses in a pulse train occurring over a period of time may be measured. Video signals to unconnected video interfaces may be disabled | 07-09-2009 |
20100148929 | Multi-protocol radio frequency identification transceiver - A transceiver for a RFID reader and a transceiver for a RFID transponder (tag) allow communication between the two devices. The RFID reader utilizes an analog front end and a digital backend. In the receiver portion of the transceiver, the front end of the RFID reader uses a pair of down-conversion mixers to demodulate a received signal into in-phase (I) and quadrature (Q) components and analog-to-digital converters (ADC) digitize the signal. A digital signal processor (DSP) in the back end processes the digital signal and uses a matched filter for data detection. The RFID tag receives an inductively coupled signal from the reader and the receiver portion of the tag uses a pulse/level detector that employs an analog comparator and a sample and hold circuit to detect the received signal. A digital decoder/controller is used to decode the incoming data and to establish a sampling clock for the pulse/level detector. An automatic gain control (AGC) circuit adjusts a receiver gain according to the received signal strength and controls tuning of magnetic coupling circuitry. | 06-17-2010 |
