A system and a method for wireless power and data transfer for connectors. The connector system is adapted for coupling two devices and for wirelessly transferring power and/or data from a first device to a second device. At the transmitting end, the system comprises of a power source, a self-resonating sinewave oscillator, a tuning circuit a, and a transmitter coil for processing and transmitting the power and/or data. At the receiving end, the system comprises a receiver coil, a proximity sensor, a signal modulator, a signal de-modulator, a bridge rectifier, a DC-DC regulator for processing and providing the power and/or date to a load.

Systems and methods for wireless power and data transfer for connectors

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

An adaptive wireless torque measurement system includes a rotor, a rotor antenna, a stator antenna, stator electronics, and rotor electronics. The rotor antenna is attached to the rotor. The stator antenna is configured to be inductively coupled to the rotor antenna. The stator electronics are coupled to receive, via the stator antenna, feedback data and are configured, in response thereto, to generate and transmit, via the stator antenna, power signals at a power level magnitude based in part on the feedback data. The rotor electronics are attached to the rotor and are coupled to receive, via the rotor antenna, the power signals transmitted by the stator electronics. The rotor electronics are configured to determine the power level magnitude of the power signals, generate the feedback data, the feedback data at least including information representative of the determined power level magnitude, and transmit, via the rotor antenna, the feedback data.

Adaptive wireless torque measurement system and method

A wireless torque measurement system includes a rotor, a rotor antenna, rotor electronics, a signal processing module, and a single ear antenna. The rotor antenna is attached to the rotor. The rotor electronics are attached to the rotor, and are configured to generate signals that indicate an amount of strain in the rotor and to transmit, via the rotor antenna, digital data representative thereof. The signal processing module is configured to generate signals that provide power and data to the rotor electronics module and process the digital data transmitted by the rotor electronics. The single ear stator is antenna coupled to the signal processing module and is configured to be inductively coupled to the rotor antenna.

Single ear stator antenna for wireless torque measurement system

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.

Coordinated ratiometric compensation for high-precision load-cells

This disclosure is directed to techniques for detecting one or more indications of rotational movement of a rotatable member. According to one example, at least one movement sensor is associated with the rotatable member and is configured to detect at least one measurement of rotational motion of the rotatable member. The at least one movement sensor is configured to be powered via at least one photoelectric element secured to the rotatable member. The at least one movement sensor is configured to communicate the at least one indication of the detected at least one measurement from the rotatable member via at least one wireless communications module associated with the rotatable member and powered via the at least one photoelectric element.
