Abstract: A torque sensor system and method. An automotive engine is located opposite a torque converter, such that a shaft extends from the engine and interacts with the torque converter. A target is located between the engine and torque converter. One or more torque sensors can be integrated with one or more position sensors for detecting a position associated with the shaft, wherein the torque sensor(s) and the position sensor(s) are integrated into a single torque sensor package to thereby provide enhanced sensing of the target in association with a rotation of shaft during an actuation of the engine.

Abstract: A die structural support apparatus and method are disclosed, in which a die component is provided. A support element can be configured for use with the die component, wherein said support element surrounds said die component, thereby strengthening said die component to provide a surrounding die support structure thereof. The die component preferably constitutes a SAW die, and may be formed from, for example, quartz. The support element can be molded, stamped, cast, machined and so forth and is preferably located with respect to the SAW die after the SAW die is formed.

Abstract: A torque sensor packaging system and method includes a torque member that includes one or more holes formed therein for receiving one or more respective fasteners associated with a sensing element. The sensing element can be connected to the torque member to the sensing element in order to transfer torque associated with the torque member to the sensing element for torque sensing operations thereof.

Abstract: A magneto-elastic torque sensor and system include a substrate and a magneto-elastic sensing component formed from or on the substrate. The magneto-elastic sensing component and the substrate together form a magneto-elastic torque sensor, which when subject to a stress associated with a torque, shifts a characteristic frequency thereof linearly in response to the torque, thereby inducing a pathway by which magneto-elastic energy is coupled to excite vibrations in a basal plane of the magneto-elastic sensor, thereby generating torque-based information based on a resonant frequency thereof.

Abstract: 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.

Abstract: 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.
