摘要： A method for testing a detection sensor positioned facing a target fixed to a drive shaft that is intended to be installed in a motor vehicle. The method includes generating a pulsed voltage test signal, amplifying the high states of the generated test signal, filtering the amplified test signal so as to obtain a voltage test signal having high states the voltage of which is higher than a predetermined high-state detection threshold and low states the voltage of which is lower than a predetermined low-state detection threshold, and detecting the high states and the low states of the filtered test signal in order to test the sensor.

摘要： A rotor arrangement and method by which a time reference is provided for a rotor. The rotor includes N time of arrival features. The method includes steps to: provide a plurality of time of arrival probes spaced apart circumferentially outside the periphery of the rotor; for each revolution of the rotor, measure a time of arrival of each feature at each probe; select N time of arrival measurements at each probe; derive a best fit of the measured times of arrival measured at all the probes against angular position; and set the time reference for the next revolution of the rotor equal to the best fit at the end of the current revolution of the rotor.

摘要： A tachometer system for an aircraft landing gear. The tachometer system includes a tachometer arranged to generate a variable voltage signal in response to the rotation of a wheel of the aircraft landing gear, and a processing system arranged to output a speed signal indicative of the rotation speed of the wheel of the aircraft landing gear. The speed signal is determined from the variable voltage signal from the tachometer using a set of determined parameters. The determined parameters of the processing system are determined from the voltage levels of the variable voltage signal.

摘要： A bicycle controller includes an electronic control unit. The electronic control unit controls a transmission device that changes a ratio of a rotational speed of a wheel of a bicycle to a rotational speed of a crank of the bicycle, and a motor that transmits torque to an upstream side of the transmission device in a transmission path of a manual driving force that is input to the crank. The electronic control unit switches between a first mode that drives the motor in accordance with the manual driving force and a second mode that allows the motor to be driven to assist walking of the bicycle. The electronic control unit controls the transmission device to change the ratio upon detection of the electronic control unit switching between the first mode and the second mode or the electronic control unit being in the second mode.

摘要： A sensing system and method for correcting an input waveform from a coded wheel. The coded wheel is configured to generate a signal that varies with rotation of the coded wheel relative to a sensor. The sensor is configured to sense the varying signal and output a corresponding input waveform. A correction module is configured to receive the input waveform and compare the input waveform to at least one stored waveform and to correct the input waveform if a defect is detected in the coded wheel in response to the comparison.

摘要： Apparatuses, systems, and methods that provide a delayed output signal with reduced sampling error are described. Embodiments include a clock circuit that generates a sample clock signal having a predetermined sample clock period. A sampling circuit may generate samples of a received signal during each sample clock period. An interpolation circuit may estimate a value of the received signal at times between the samples of the received signal based on at least a first sample and a second sample of the received signal. The interpolation circuit may estimate a time that the received signal crosses a threshold, and determine a time delta between the first sample and the estimated time that the received signal crosses the threshold. A delay circuit to generate a time delay substantially equal to the time delta is also included. An output signal changes state after the generated time delay.
