    摘要: A sensor system includes a sensor circuit and a plurality (e.g., N-number) of radio frequency identification (RFID) tags. The sensor circuit senses a physical parameter and supplies N-bits of digital sensor data. Each of the RFID tags at least selectively receives a digital sensor signal representative of one of the N-bits of digital sensor data and selectively transmits the digital sensor signal it received.

    摘要: A smart power conversion and control system and method converts source AC power at a first voltage level to DC power at a second voltage level that is less than the first voltage level. Upon receipt of a command signal, a portion of the system is enabled to further convert the source AC power to regulated DC power at a voltage level that is less than the first voltage level and greater than the second voltage level. One or more relatively high voltage DC loads are then energized with the regulated DC power. When the portion of the system is not enabled, the source AC power is not converted.
