摘要： The semiconductor device includes a frequency output circuit that outputs a clock signal having a specified frequency, a circuit block that realizes a predetermined function, and a standby controller that controls a standby mode of the circuit block in accordance with the clock signal. Here, the standby controller includes a control circuit that outputs state information corresponding to the control of the standby mode, a frequency control signal that designates the frequency of the clock signal output from the frequency output circuit in accordance with the state information, and a frequency selection circuit that outputs count information that designates the duration of the state transition of the circuit block.

摘要： A throttle control system for a vehicle includes a controller comprising at least one processor and at least one non-transitory computer-readable medium, a throttle valve movable between valve positions, an input sensor to transmit a target position, and a position sensor configured to detect an instantaneous disposition of the throttle valve at one of the valve positions. The controller executes instructions stored in the at least one non-transitory computer-readable medium. The controller receives the target position signal and the detected position signal. The processor compares the target position signal and the detected position signal to the instructions, selects an output signal, and transmits the output signal to the throttle valve. A first fuzzy control acceleration, a brake deceleration, and a second fuzzy control acceleration based on the output signal are applied to move of the throttle valve toward the target position.

摘要： There is provided a blade angle feedback system for an aircraft-bladed rotor rotatable about a longitudinal axis and having an adjustable blade pitch angle. A feedback device is coupled to rotate with the rotor and to move along the axis with adjustment of the blade pitch angle. The feedback device comprises a body having position marker(s) embedded therein, the body made of a first material having a first magnetic permeability and the position marker(s) comprising a second material having a second magnetic permeability greater than the first. Sensor(s) are positioned adjacent the feedback device and configured for producing, as the feedback device rotates about the axis, sensor signal(s) in response to detecting passage of the position marker(s). A control unit is communicatively coupled to the sensor(s) and configured to generate a feedback signal indicative of the blade pitch angle in response to the sensor signal(s) received from the sensor(s).

摘要： A method for controlling a motor-vehicle electronic control unit with a view to acquiring the measurement of a physical quantity using a digital sensor connected to the electronic control unit, in which method the sensor sends measurement digital data with a send period and the electronic control unit processes these measurement data with a processing period, the send period being shorter than the processing period. At the end of each processing period, the average value of the measured physical quantity is determined over an interval of N preceding processing periods.

摘要： A system includes a control circuit and an adjustable low-pass filter. The control circuit is configured to receive an input signal and to control at least one engine output based on the input signal. The adjustable low-pass filter receives the input signal, and filters the input signal prior to forwarding the input signal to the control circuit. The adjustable low-pass filter has a first setting in which the adjustable low-pass filter has a first cut-off frequency and a second setting in which the adjustable low-pass filter has a second cut-off frequency. The first setting configures the control circuit to be used with a first sensor having a first dynamic range and the second setting configures the control circuit to be used with a second sensor having a second dynamic range.

摘要： A system and method for dynamically deactivating engine cylinders of an engine equipped with a cylinder deactivation system, where the system and method control torsional vibration in the engine while deactivating cylinders using a computer programed with a desired firing density and a controlled range of engine vibration frequencies. The computer dynamically determines a cylinder firing pattern that provides the desired firing density while optimizing a cost function norm in the controlled range of engine vibration frequencies. The cylinder deactivation system in the engine is then controlled using the determined cylinder firing pattern.
