Abstract: A sensor for sensing stress in a ferromagnetic material includes a non-magnetic substrate. The substrate has a first surface and a second surface opposite the first surface. A first coil is attached to or formed on the first surface of the substrate. The first coil is configured to induce a magnetic flux in the ferromagnetic material being driven by an alternating current (AC) signal. At least one second coil is attached to or formed on the first surface of the substrate. The at least one second coil is spaced from the first coil. In addition, the second coil is configured to detect changes in the magnetic flux induced in the ferromagnetic material.

Abstract: An apparatus includes at least one energy source and a drive system coupled to the at least one energy source. The drive system converts electrical power received from the at least one energy source and provides converted electrical power for driving at least one load. The drive system includes a first converter, a second converter, and a first switch module coupled to outputs of the first and second converters. When the apparatus is operating under a first mode, the first switch module is switched to assume a first state to allow a first output electrical power provided from the first converter and a second output electrical power provided from the second converter to be combined for driving a first load with the combined output electrical power.

Abstract: A calibration apparatus is configured to calibrate a magnetostrictive sensor. The magnetostrictive sensor is configured to measure an object and comprises a sensing element positioned adjacent to the object. The calibration apparatus comprises an estimation device and a calibrator. The estimation device is configured to estimate at least one of a gap between the sensing element and the object and a temperature of the object to obtain at least one of an estimated gap and an estimated temperature, based on geometric information, an excitation signal and an output signal of the magnetostrictive sensor, and geometric information of the object. The calibrator is configured to reduce an effect on the output signal of the magnetostrictive sensor imposed by variations in the at least one of the gap and the temperature, based on the at least one of the estimated gap and the estimated temperature, to obtain a calibrated output signal.
