摘要： A sensing device includes a Wheatstone bridge and a source of a stimulation configured to apply the stimulation across two electrodes of the Wheatstone bridge. The device also includes a timing sensitive circuit configured to detect timing of a signal appearing across one of the other electrodes of the bridge as a result of the stimulation being applied. The timing provides a way to read the sensor. The device can be powered remotely and data so read can be transmitted using the remote power. The timing sensitive circuit includes a comparator. The comparator provides a high logic signal for a time related to the reactance of one leg of the Wheatstone bridge, and that provides a reading of a differential sensor having elements in each leg of the bridge.

摘要： The novel temperature gradient compensation circuit is designed to overcome temperature gradient problems in inductive or capacitive circuits, such as, differential variable reluctance transducers. The system comprises, in one embodiment, the use of an inductive or alternating current bridge which sends its output to a low pass filter in order to remove the alternating current component of the bridge output. The output of the low pass filter is fed into an instrumentation amplifier whose gain can be adjusted. The output of this instrumentation amplifier is a signal that is proportional to the temperature gradient experienced by the alternating current bridge. The output of the alternating current bridge is also fed to a high pass filter and then sent to a demodulator and amplifier. By subtracting the direct current output from the alternating current output, the effects of temperature do not have an effect upon the result.

摘要： An electronic system includes a reader and a remotely powered and remotely interrogated sensor transponder. The sensor transponder includes a coil or an antenna, a switched reactance circuit, a processor, and a sensor. The sensor transponder receives power radiated from the reader to the coil or antenna. The sensor uses the power for sensing. The sensor transponder is capable of processing sensor data in the processor and transmitting the sensor data to the reader using the switched reactance circuit. In one embodiment, the receiver coil or antenna is part of a resonant tank circuit which includes an impedance matching circuit. The impedance matching circuit is connected to the receiver coil or antenna to provide greater current to the sensor or other power-using device than would be available to the sensor or other power-using device if the sensor or other power-using device were connected between the first and second end. The impedance matching circuit can be two or more taps to the coil or antenna.
