    摘要： A Hall effect switching circuit including a Hall effect device having two input contacts and two output contacts. A source of electric power is connected across the two input contacts, and one of the output contacts is connected to the emitter of a transistor and the other output contact is connected to the base of the transistor through a diode. A resistor connects the base of the transistor to a terminal of the source of electric power.

    摘要： A contact-less limit switch for path-responsive release of switching procedures, which comprises a housing, a magnet producing a magnetic field and disposed in the housing. At least one field plate has electric current flowing therethrough, and is disposed within the range of the magnetic field. The resistance of the at least one field plate is variable by the magnetic field, and a member is provided which is operable from the outside for varying within selected limits the density or position of the magnetic field with respect to the field plate.

    摘要： This invention relates to a noncontacting shaft position indicator utilizing the responsive properties of a magnetosensitive device. Shaft position is determined from the variation of the intensity and direction of the magnetic flux linking a rotor on the shaft and a fixed stator. The varying magnetic flux phase and amplitude modulates the high frequency input signal of a magnetosensitive device interposed in the flux path. The phase modulation information is utilized to generate a trigger pulse which is in synchronism with the instantaneous shaft position. Electrical means are provided to further shape the magnetic field to provide a means of retarding or advancing the generation of the trigger pulse in relation to the instantaneous shaft position.
