According to techniques of this disclosure in various examples, a wireless signaling system may include a stationary element such as a stator and a non-stationary element such as a rotor. The stationary element includes a stationary element controller. The stationary element is configured to transmit a wireless signal comprising a pair of pulses. The non-stationary element comprising a non-stationary element controller. The non-stationary element is configured to receive the wireless signal from the stationary element controller, measure a transition in voltage of each of the pulses and a time interval between the pulses, and interpret a signal based on the transition in voltage of each of the pulses and the time interval between the pulses.

Wireless telemetry using voltage and pulse intervals

A system includes a rotor, a rotor antenna attached to the rotor, a strain detection device attached to the rotor, a programmable gain amplifier attached to the rotor, and a control module attached to the rotor. The strain detection device is configured to generate signals that indicate an amount of strain in the rotor. The programmable gain amplifier is configured to amplify the signals generated by the strain detection device by a gain value. The gain value is programmable. The control module is configured to program the gain value of the programmable gain amplifier and transmit, via the rotor antenna, digital data that is derived from the amplified signals.

Wireless torque measurement system using programmable gain amplifier

Apparatus and associated methods relate to a load-cell measurement system having an output that is substantially independent of the system voltage source, by providing compensation for the source voltage variation using both a compensating offset voltage and a compensating reference voltage, these compensating voltages having a predetermined relationship with each other. In an illustrative example, the supply voltage may be directly connected to a load-cell, an instrumentation amplifier, and a compensation circuit. In some examples, the compensation circuit may include a chain of impedances which may generate two mutually related voltages both being scaled to the supply voltage. The first scaled voltage may, for example, substantially compensate offset of the load-cell measurement system. The second scaled voltage may, for example, substantially compensate for gain. In various examples, the compensating offset voltage and gain voltage may have a predetermined relationship so as to provide coordinated compensation of the system.
