摘要： A device is described for determining and/or controlling the operating data of automotive vehicles, particularly for controlling the velocity of vehicles with internal combustion engines and electric transmission of the position of the gas pedal to an electric setting element which is connected to the throttle valve or the displacement device of the injection pump, the device having a measuring device for determining shunt resistances to the electric position transmitter which is connected to the gas pedal and the throttle valve. Such shunt resistances (leak resistances) detrimentally affect the desired precise relationship of the position of the gas pedal to the position of the throttle valve.

摘要： A potentiometer position switch circuit which includes a meter mechanism having a low friction potentiometer coupled to move therewith. The output of the low friction potentiometer is coupled together with the output of a set point potentiometer across the input terminals of a comparator. A magnetic latching double pole, double throw relay having set and reset relay coils is connected to the output of the comparator through the gate of a first voltage operated transistor and through sufficient resistance to minimize current drain and also through an invertor to the gate of a second voltage operated transistor and through a second resistor of sufficient resistance to minimize current drain. The output of the first voltage operated transistor is connected from a second voltage source through the set relay coil to ground and the output of the second voltage operated transistor is connected from a voltage source through said reset relay coil to ground. One set of contacts on the relay are connected to ground the gate on said second transistor when the voltage on the gate of the first transistor is high and to ground the gate on the first transistor when the gate on the second transistor goes high. The other set of contacts are connected to actuate a utilization circuit in one or the other position.

摘要： An adjusting device with an overload slip system and a slip-independent position indicator includes a driving system and an adjusting member movable by the driving system between two end stops. The driving system includes an electric motor housed in a housing and a planetary transmission connected to the motor shaft, the power output shaft of the transmission being in engagement with the adjusting member. A stationary, internally toothed ring of the planetary transmission is confined between facing peripheral edges of the divided housing and is capable of slipping relatively to the edges of the housing under overload conditions. A support plate with a circular electrical resistor is fixedly connected to the housing on the side of the power output shaft. A runner contact connected to the power output shaft is movable over the resistor. The support plate with the electrical resistor and runner contact form a position indicator operating as a potentiometer, which continues to indicate the exact position of the adjusting member when slip occurs.

摘要： In one aspect, an integrated circuit (IC) includes a magnetic field sensor to detect speed and direction of angular rotation of a rotating magnetic structure. The magnetic field sensor includes at least two magnetic field sensing elements configured to sense changes in a magnetic field caused by rotation of the magnetic structure. The IC also includes an output port configured to provide an output signal of the magnetic field sensor. The frequency of the output signal indicates the speed and the direction or indicates a fault.

摘要： A method and a device are provided for controlling a rotation angle of a swinging head of a fan. The method may be applied in a fan adopting a brushless motor. An angle feedback device is arranged on the swinging head, and the swinging head is driven by the brushless motor to rotate. The device may acquire a parameter outputted by the angle feedback device, where the parameter varies with rotation of the swinging head. The device may calculate a current rotation angle of the swinging head according to the parameter outputted by the angle feedback device and a preset correspondence relationship between parameters and angles. The device may control the swinging head to rotate according to the current rotation angle of the swinging head and a preset target rotation angle.
