摘要： A pressure transducer for providing an output signal having a value determined by an input pressure differential includes a capacitance manometer (10) having a first input (24) for receiving a first input pressure and a second input (25) for receiving a second input pressure, the capacitance manometer (10) having a capacitance determined by the difference between the first and second input pressures, and an output circuit connected to the capacitance manometer (10) for providing an output signal having a value dependent upon the capacitance.

摘要： An access control card for use in an access control system includes a battery (14), a wireless signal sensor such as an antenna (11) for receiving coded wireless signals such as coded radio frequency signals generated by a card reader, a clock and receiver (20) connected to the battery and antenna for supplying a received signal based upon the coded radio frequency signal, a memory (50) for storing first and second stored codes, and a comparator and transmit circuit (80) for comparing the first stored code to the received signal and for transmitting the second stored code when there is a match between the received signal and the first stored code.
