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 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: An apparatus and method for detecting gear features is provided. The apparatus includes a magnetic-sensing element, a thresholding module, and an output module. The magnetic-sensing element may provide a sensor-output signal indicative of the presence of a gear feature. The thresholding module may (i) transform the sensor-output signal into a characteristic waveform, which is also indicative of the presence of the gear feature; (ii) detect a first difference between the characteristic waveform and a reference signal, and responsively provide a tracking signal that tracks this difference; and (iii) detect a second difference between the tracking and reference signals, and responsively adjust the sensor-output signal. Adjustment may be performed (i) as a function of the second difference when it falls below a given threshold and (ii) by a predetermined amount when the second difference satisfies the given threshold.

Abstract: A magnetic sensor is provided which utilizes a molded magnet with a channel formed therein. A magnetically sensitive component, such as a Hall effect element, is attached to a substrate or printed circuit board. The printed circuit board, or substrate, is provided with an opening through its thickness that is shaped to accept a post with a certain amount of clearance therebetween. This allows the printed circuit board to be moved relative to the magnet during calibration procedures and then rigidly attached in a position relative to the magnet by soldering the post to the substrate or printed circuit board. This places the magnetically sensitive component at a desirable location relative to the magnet and within the channel formed in the magnet. The post can be molded into the magnet or formed as an integral portion of the magnet.
