摘要： A piston position sensing circuit for sensing the instantaneous position of a piston of a free piston Stirling machine or a compressor mechanically connected to a reciprocating member of a linear electric motor or alternator. A source of a high frequency, alternating, electrical signal applies a high frequency signal to the winding circuit of the linear alternator or motor. A filter circuit is connected to the winding circuit and passes electrical signals at the frequency of the high frequency source and blocks signals at the operating frequency of reciprocation. A peak detector circuit is connected to the filter circuit and detects the peak of the filter circuit output signal to provide an instantaneous peak magnitude that is proportional to the instantaneous piston position.

摘要： An inductive position sensor has a spatially periodic scale with a series of conducting or permeable features of pitch T and a reading head with drive windings and sense windings, facing the scale with a spatial period 2T along the scale. The windings are each divided in two identical winding elements having the same relative location within two identical winding element patterns having a center-to-center distance along the scale of NT+T/2, N being an integer, and connected so that the winding element polarities in each winding are either opposed for drive windings and the same for sense windings or the same for drive windings and opposed for sense windings. Thereby, direct couplings in both patterns cancel each other, while the spatially periodic signals coupled via the scale reinforce each other.

摘要： A turbine wheel of a turbocharger has a turbine blade. The turbine blade has a fin shape of which width in the rotation direction of the turbocharger is narrow, and is projected from the base portion of the turbine wheel. An inclined part of the turbine blade is inclined with respect to the rotation direction of the turbocharger. A coil is disposed so that the inclined part passes nearby as the turbine wheel rotates in a posture that an end in the center axis direction is directed toward the turbocharger. A detector detects a change in inductance, which occurs when the inclined part of the coil passes nearby.

摘要： A method and a device for determining motion parameters of a conductive, profiled surface (22) relative to a sensor (3), with the sensor (3) comprising at least one coil for generating an electromagnetic alternating field, which is subjected, because of the feedback resulting from position changes between the surface (22) and the sensor (3), to a variation, which is determined by means of the coil (16). The position change is derived from the coupling impedance (Zc) of the coil (16), and the real component (Rc) and the imaginary component (Xc) of the complex coupling impedance (Zc) of the coil (16) are determined, with a distance d between the sensor (3) and the surface (22) being computed based on the determined values while using an algorithm as a basis.

摘要： A device and method for detecting the position and velocity of a test object relative to a sensor, the sensor and the test object being arranged such that they can be displaced relative to one another. In one embodiment, the sensor has a measuring coil with one or more voltage tap(s) and has a target that is placed on the test object while being electromagnetically coupled to the measuring coil. An electronic component for adding the voltages tapped on the sensor is assigned to the sensor. The invention is, with regard to a simplest possible design of the sensor, characterized in that for simultaneously measuring position and velocity, the target comprises two parts, one part being made of an electrically conductive material and the other part being provided in the form of a magnet, and in that an evaluation circuit determines, based on the output signal of the electronic component for adding the tapped voltages, a voltage component Up that is proportional to the position of the target, and a voltage component Uv that is proportional to the velocity of the target.

摘要： The method of synchronizing the analogue display (41) of a timepiece (40), including an electronic time base (64), is achieved using proximity sensors (60, 62) respectively associated with wheels (46, 48) each having an aperture (54, 56) for defining the angular position of the latter. Determination of the angular position of a wheel requires an angular distance of around 60° to 90° to be travelled with this type of proximity sensor. Dependency of the measurement results upon the temperature generates a problem of precision in determining the angular position of the wheels, in particular a wheel secured to the hour indicator, given that an angle of 60° to 90° corresponds to a time interval of 2 to 3 hours. In order to ensure a measurement in a relatively short time interval where the ambient temperature is substantially constant and thus has no influence on the measurement, the invention provides that, in a analogue display synchronization mode at least one indicator is driven in an accelerated advance mode so that the aperture provided in the corresponding wheel quickly passes opposite the proximity sensor associated with that wheel.

摘要： An inductive position sensor for rotary motion includes a transmitter coil and a receiver coil, the receiver coil generating a receiver signal when the transmitter coil is excited by an alternating current source. A moveable coupler element modifies the inductive coupling between the transmitter coil and the receiver coil so that the receiver signal is sensitive to the coupler element position. The ratio between the receiver signal and the reference signal is sensitive to the coupler element position, but substantially insensitive to common mode factors. The angular or positional range of the position sensor can be increased using a plurality of receiver coils.
