摘要： An SDARS receiver includes an analog front end configured to receive a composite signal. An A/D converter is coupled to the analog front end and converts the signal to a digitized signal. A digital down converter (DDC) is coupled to the A/D converter and down converts the digitized signal to a down converted signal. A demodulator demodulates the down converted signal. The receiver includes a digital automatic gain control (DAGC) coupled to an output of the A/D converter and before the demodulator. An automatic gain controller is coupled to the DAGC for providing an automatic gain control signal.

摘要： Method and device for smart power management of the sensor nodes within a wireless sensor network to achieve extremely low standby current and fast power-up time at the same time are provided. The method features a technique of centralized remote power-up scheme combined with local broadcasting power-up sequence to achieve fast power-up time and extended power-up coverage. It can manage the power-down sequence from a base-station to sensor nodes sequentially, while the power-up sequence broadcasts its power-up command from the base-station to all the sensor nodes within a sensor network. The device accepts same frequency band for both data communication and power-up message, and a RF switch separates receiving RF data and RF power-up message. The wireless power-up receiver is self-powered from power-up message and also generates power-up enable signal from it.

摘要： A Wireless battery area network permits the wirelessly monitoring and controlling of individual batteries within large-scale battery applications. The system automatically configures its wireless nodes in the network and provides for the linking of a plurality of batteries (10) to a master battery management unit (M-BMU) (100) by establishing a wireless battery area network within a battery pack that include slave units (S-BMU) (210). The entire system may also be controlled by a top level battery management unit (T-BMU) (510). The system and method allows for the monitoring of voltage, current, temperature, or impedance of individual batteries and for the balancing or bypassing of a battery.
