Fastening apparatus for an electronic device and method for fastening an electronic device

The invention relates to an inductive proximity sensor for determining the presence and/or the distance of an electrically conductive object which is designed to evaluate an oscillation in the form of an analog signal whose amplitude depends on the presence or absence and/or on the distance of an electrically conductive object. In accordance with the invention, the inductive proximity sensor includes at least one A/D converter which converts this analog signal into a digital input signal and includes at least one mixer which multiplies the digital input signal by a digital reference signal to form a digital output signal, wherein the digital reference signal is identical to the digital input signal or only differs from the digital input signal by a constant factor. The invention further relates to a method for determining the presence and/or the distance of an electrically conductive object with the aid of a proximity sensor.

The present invention relates to a proximity sensor having a first transmission coil, a second transmission coil, at least one reception coil, an excitation device which is connected to the first and second transmission coils, and an evaluation unit which is connected to at least one transmission coil and/or to the excitation device as well as to the at least one reception coil.

The invention relates to an inductive proximity sensor with a sensor element which includes a resonant circuit which provides an output signal which depends on the damping by an electrically conductive object. In accordance with the invention, the inductive proximity sensor has a &#x3a3;&#x394; modulator for the evaluation of an output signal of the resonant circuit. The invention furthermore relates to a method for the determination of the presence and/or of the spacing of a metallic object with the help of an inductive proximity sensor.

A magnetic sensor for determining positions of an activation magnet along a monitored distance with at least two sensor elements. Both sensor elements are subjected to at least one component of a magnetic field of the activation magnet. An evaluation unit coupled to the sensor element generates at least one switching element that corresponds to a desired magnet position. Each sensor element is operative over the entire monitored distance, and for each desired magnet position there is one unambiguous group of signal values which is used by the sensor elements for generating the switching signals in the evaluation unit.

Magnetic sensor

A sensing system having at least one magnetic or inductive sensor for determining the position of a piston. The sensor system has a positioning device with which at least two sensing positions for the sensing system can be set and adjusted.

Sensor

An inductive proximity sensor has an oscillatory circuit (L, C, R ), an electric energy source ( ) coupled to the oscillatory circuit for compensating losses in the circuit, and a filter ( ) for compensating signal changes encountered in the oscillatory circuit. The input of the filter is coupled to the oscillatory circuit and its output is coupled and sending output signals to the energy source. The energy source changes the energy or current supplied to the oscillatory circuit as a function of the output signals from the filter to thereby actively compensate for signal changes encountered in the oscillatory circuit.

An inductive proximity switch includes an electrical resonant circuit and an energy source coupled therewith to compensate for losses in the resonant circuit. The energy source is fully differentially coupled with the resonant circuit at the input side.
