摘要： An electromagnetic transducer which generates signals on the basis of the Barkhausen effect under periodically alternating externally applied magnetic switching fields. Prior to use, the magnetic sensor element, for example a ferromagnetic wire, is pre-magnetized by undergoing a program which subjects the wire to a coercive applied field substantially higher than the alternating interrogation field. The coercive field places different zones of the wire into magnetic saturation with varying relative polarity, thereby creating two or more zones of different magnetization. When subjected to the alternating, low intensity interrogation field, sensor coils detect a high level, bipolar output signal.

摘要： A signal generating means comprising a bistable magnetic device which alters its magnetic state when the density of magnetic flux to which it is subject passes through a predetermined value, and detecting means providing an output signal responsive to a change in magnetic state of said bistable device. A conducting means comprising first and second portions conducts magnetic flux in first and second paths and subjects the bistable magnetic device which is connected between the first and second portions to the conducted magnetic flux. The second portion provides the second path with an alterable permeance for varying the reluctance of the second path of the conducting means, and an energizing means provides magnetic flux to the conducting means having a sense along the first path through the bistable device which is opposite to its sense in the second path. The density and sense of magnetic flux to which the bistable device is subject to changes with the variation of reluctance of the second path of the conducting means to alter its state.

摘要： The reading head comprises a core, which carries an electric detector winding and which may be E-shaped for reading two rows of Wiegand wires or U-shaped for reading one row of Wiegand wires. Two platelike permanent magnets are spaced from the outer legs of the core. One pole face of each permanent magnet is covered by a low-reluctance element, which terminates close to the core in a top plan view on the reading surface. The core and the magnets include such an oblique angle that in the reading surface of the reading head each low-reluctance element is spaced in the reading direction from the adjacent free leg end of the core. This arrangement ensures that during the reading operation each Wiegand wire will first enter the relatively extensive magnetic field established between those pole faces which are not covered by low-reluctance elements. Thereafter, the Wiegand wire is trigger and then enters the region between the low-reluctance elements and is saturated in that region. That concept permits the design of a reading head which has a short overall length and in which high signal amplitudes are obtained.

摘要： To simplify a Wiegand wire type pulse source, a Wiegand wire (4) has a coil (3) wound thereon. A permanent magnet (5) is positioned with a gap from the coil, and a magnetically permeable masking element, for example a sector-shaped disk, is movable between the magnet and the coil. The coil (3) is connected to a source of direct current (B) which so magnetizes the Wiegand wire (4) that, when a gap of the masking element occurs between the magnet (5) and the coil (3), the Wiegand wire is reversely magnetized until, again, a solid portion of the masking element is interposed in the gap between magnet (5) and coil (3) to restore the magnetic direction due to the battery (B). Re-magnetization pulses are picked off the coil (3) by a suitable pulse coupling element such as a capacitor (C).

摘要： An internal combustion engine spark ignition system includes a transducer and a transducer circuit which coact to produce a rectangular pulse for each spark required. The leading edge of this pulse controls an input transistor which controls an output transistor through an intermediate transistor. The output transistor in turn controls an ignition circuit controlling the current through an ignition coil. The coupling between the intermediate and output transistors includes a resistance chain to points in which two timing capacitors are connected. At high speeds the circuit provides a fixed coil current duty cycle with a relatively short off time, whereas, at low speeds the duty cycle is determined by the length of the pulses from the transducer circuit giving a relatively long off time.
