    摘要: Many mechanical systems contain rotating parts used to transfer power from one part of the system to another. The system's efficiency and longevity can be increased by measuring the speed and loading of the rotating parts. Passive wireless sensors are ideal for instrumenting rotating parts because they require no connecting wires and no stored energy. The sensor measurements contain read errors when the stationary interrogation circuit and the rotating sensor are not ideally aligned. The read errors are a function of the angular offset between the stationary interrogation circuit and the passive sensor. As such, the read errors are deterministic. A measurement of the angular offset between the stationary interrogation circuit and the passive sensor is used to determine a correction factor that cancels out the read error to produce a compensated sensor signal.

    摘要: A device, system, and method for measuring torque, comprising an acoustic wave device removably attached to a rotatable shaft by a variably-shaped retainer, wherein removal of the acoustic wave device with the variably-shaped retainer facilitates servicing and replacement of the torque measurement device. The acoustic wave device can be removably attached to the rotatable shaft by using one or more connectors. Other acoustic wave devices such as acoustic wave resonators, surface acoustic wave delay lines, surface acoustic wave filters, and surface transverse waves can also be removably attached to the rotatable shaft to measure torque.
