摘要： An inductive joystick includes a movable actuator which carries an element of electrically conductive low magnetic permeability material (e.g., copper or aluminum), such that movement of the actuator differentially affects the coupling between a primary coil and a pair of secondary coils which are encircled by the primary coil. The arrangement provides a desirable output characteristic, in which the minimum output of each secondary coil is preferably greater than the maximum difference between the outputs of the two secondary coils, useful for detecting component failure. The secondary coils are preferably connected in a processing circuit which rectifies the outputs of the two coils before combining them to form a resultant "difference" output.

摘要： A rotation angle detection sensor system for a rotational body is provided, which has a reduced sensitivity against an interfering magnetic field and an interfering electric field. The rotation angle detection sensor system comprises an encoder structure that is attached to the rotational body of a machine and is movable along with this rotational body. A stationary sensor assembly is positioned opposite to this encoder structure and supplies at least one sensor signal for determining the angle position. The sensor assembly includes a first inductive element, the inductance of which is dependent on the angle position of the encoder structure.

摘要： A motor-driven throttle valve control device having high reliability and resistance to electrostatic noise from the gear cover connector is obtained by compactly forming an inductance-based noncontact rotation angle detecting device at the end of the throttle shaft. In the present invention, an excitation conductor is attached to the tip of the throttle shaft to which the throttle valve is attached. The gear cover is provided with a magnetic field exciting conductor and a signal detection conductor to face the excitation conductor. Further, an insulating member is arranged between the rotating shaft (throttle shaft) and the magnetic field exciting conductor and signal detection conductor. With this configuration, a motor-driven throttle valve control device having an inductance-based noncontact rotation angle detecting device, not affected by electrostatic noise and having high reliability, is realized.

摘要： A device for monitoring the tolerances of a workpiece has a measuring probe with two separate inductive coils arranged in a housing. A non-magnetizable sensing stylus designed to rest on a workpiece surface to be measured is arranged in the coils and has a deflector body that is a sleeve. The stylus and the deflector body are loaded into a measuring position. The housing has two essentially identical housing halves each having a plane surface with which the housing halves are connected to one another. The housing halves each have a recess and one of the inductive coils is inserted into one of the recesses, respectively. The opposed ends of the housing halves are provided with aligned bores that open into the recesses, respectively. The stylus is arranged coaxially in the inductive coils and has opposed stylus ends projecting through the bores outwardly from the two housing halves.

摘要： Primary coils generate flux upon being excited by a predetermined ac signal. A stator is made in a plate-like configuration and has plural primary coils independently in the circumferential direction so that flux is generated by the primary coils in the direction of the axis of rotation. A rotor is provided displaceably relative to the primary coils to change reluctance with respect to the flux generated by the primary coils. Accordingly, as the rotor is rotated, reluctance change is produced due to the relative positional relation between the primary coils provided in the stator and the rotor. This reluctance change causes to change self-inductance of the primary coils and affects the exciting ac signal flowing through the primary coils and, therefore, by outputting the self-induced ac signal in the primary coils, the relative positional relation between the rotor and the primary coils, i.e., the rotational position of the rotor, can be detected.
摘要翻译：初级线圈在被预定的ac信号激励时产生通量。定子被制成板状构造，并且在圆周方向上独立地具有多个初级线圈，使得在初级线圈沿着旋转轴线的方向产生磁通。转子相对于初级线圈可移位地设置，以相对于由初级线圈产生的磁通来改变磁阻。因此，随着转子旋转，由于设置在定子和转子中的初级线圈之间的相对位置关系，产生磁阻变化。该磁阻变化导致初级线圈的自感变化，并且影响流过初级线圈的励磁交流信号，因此通过在初级线圈中输出自感应交流信号，转子与转子之间的相对位置关系可以检测初级线圈，即转子的旋转位置。

摘要： A duty cycle is used in conjunction with a powered oscillator to electronically reduce the current draw by reducing the average tail current and thus reducing the sensor radiated emissions without altering an inductive position sensor. The duty cycle enables an on and an off cycling without altering the hardware but providing the improvements.
