摘要： A battery depassivation system includes a depassivation circuit, a battery connect/disconnect circuit, and a processor. The depassivation circuit is adapted to be electrically coupled in series with a battery. The depassivation circuit is also coupled to receive an ENABLE signal and is configured, upon receipt thereof, to draw current from the battery. The battery connect/disconnect circuit is adapted to be electrically coupled in series between the battery and one or more battery-powered electronic circuits. The battery connect/disconnect circuit is coupled to receive an ISOLATE signal and is configured, upon receipt thereof, to electrically disconnect the one or more battery-powered electronic circuits from the battery. The processor is adapted to couple to the battery and is configured, upon being coupled thereto, to determine if the battery needs depassivation and implement a depassivation routine if the battery is determined to need depassivation.

摘要： A system and method for estimating the residual fatigue life of a load cell includes storing, in a memory, fatigue life reference data associated with a test load cell. A predetermined number of data storage bins are provided. Each data storage bin is representative of a predefined value range of peak loads. Peak loads applied to an in-service load cell are detected, and each is stored in an appropriate one of the data storage bins. A number of load cycles of the in-service load cell are calculated based on the detected peak loads stored in each of the data storage bins. An estimate of the residual life of the in-service load cell is calculated from the fatigue life reference data and the calculated number of load cycles of the in-service load cell.

摘要： A torque measurement system that includes a rotor device and a stator device can perform automatic tuning to improve the initial tuning performed during design and assembly. The stator device can include a variable capacitive element and a micro-controller configured to adjust a capacitance value of the variable capacitive element. Additionally or alternatively, the rotor device can include a variable capacitive element and a micro-controller configured to adjust a capacitance value of the variable capacitive element. The adjustment of the capacitive elements can be based on the quality of signal detected at either the rotor device or stator device.

摘要： A sensor assembly may include a Wheatstone bridge with one or more sense elements, an amplifier coupled to the Wheatstone bridge for providing a sensor output signal, a resistor, and a switch for connecting the resistor between the sensor and an adjustable power source output to induce an offset in the sensor output signal. In some instances, a controller may perform an automatic shunt calibration procedure by activating the switch to connect the resistor between the sensor and the adjustable power source output to induce an offset in the sensor output signal. The controller may read the output value and compare the output value with a predetermined value. The controller may adjust the power source output to a value that moves the sensor output value toward the predetermined value. The controller may repeat the reading, comparing and adjusting step until the sensor output value is within a predetermined range of the predetermined value.
