摘要： The primary circuit and the secondary circuit are electrically insulated from each other by the transformer so as to operate at different reference potentials. The primary coil has a first end which is driven by an input signal. The primary coil has a second end which is driven by an output signal of the delay element. An induced voltage of the secondary coil is input to the retention element, which, in turn, switches and retains a value of the output signal, based on the induced voltage of the secondary coil.

摘要： A sensor including a set of coils. The set of coils include a first coil and a second coil, wherein the first coil upon receiving energy, generates an electromagnetic near-field, such that the electromagnetic near-field provides at least a portion of the energy to the second coil through inductive coupling, inducing a current to pass through the set of coils. Further, a detector for measuring a voltage across at least one of the first coil or the second coil, wherein the detector includes a voltmeter. Finally, a processor for detecting a presence of a target structure in proximity to the set of coils upon detecting a change in a value of the voltage, wherein the target structure is an electromagnetic structure moving at a distance from the set of coils.

摘要： A pulse-induction displacement transducer comprising at least one coil component (100,150), at least one target (112,174), and pulse induction circuitry (102,152} constructed and arranged to cause a pulse of electrical current to pass through the said at least one coil component (100,150). The pulse ends abruptly. Subsequently, the electrical current passing through the said at least one coil component (100,150), or the voltage across it, is measured at a time when any electrical current through or voltage across the said at least one coil component (100, 150) would have died away in. the absence of a target. This provides an indication of the relative position between the target (112,174) and the said at least one coil component (100, 150). The said at least one coil component (100,150) comprises a first terminal portion (108,158), a first coil part (104,152) connected directly or indirectly to the said first terminal portion (108,158) and wound in one sense. The coil component (100,150) also comprises, in series with the said first coil part (104, 152), a second coil part (164) wound in the opposite sense. The said second coil part (106,164) is connected directly or indirectly to a second terminal portion (110, 168). The said pulse induction circuitry (102,152) is connected between the said first terminal portion (108,158) and the said second terminal portion (110,168).

摘要： A control device includes a moving portion, a magnetic element coupled to the moving portion, at least one magnetic sensing circuit responsive to magnetic fields, and at least one magnetic flux pipe structure. The magnetic element may comprise alternating positive and negative sections configured to generate a magnetic field. The magnetic element may be any shape, such as circular, linear, etc. The magnetic sensing circuit may be radially offset from the magnetic element, and the magnetic flux pipe structure may be configured to conduct the magnetic field generated by the magnetic element towards the magnetic sensing circuit. The magnetic element may generate the magnetic field in a first plane, and the magnetic sensing may be responsive to magnetic fields in a second direction that is angularly offset from the first plane. The magnetic flux pipe structure may redirect the magnetic field towards the magnetic sensing circuit in the second direction.

摘要： An inductive proximity switch with a housing formed of a nonmagnetic, high-grade steel, with a transmitting coil, two receiving coils which are connected in series in opposite directions and which are located symmetrically relative to the transmitting coil, and an evaluation circuit which is connected to the receiving coils. At a given size, the inductive proximity switch has a relatively large operating distance and the operating distance is largely stable, especially is largely independent of temperature, essentially in that, on the back of the receiving coils, opposite the influence side, there is a pre-damping element and the pre-damping properties of the pre-damping element at least approximately correspond to the pre-damping properties of the housing on the influence side.
