    摘要： Offset voltage control means are provided for a semiconductor type Hall cell. The control means includes one or more auxiliary electrodes disposed at preselected spatial positions of the cell between the latter''s current and sense electrodes. The auxiliary electrode(s) when connected to a predetermined electrical supply provide an auxiliary electrical field which controls the offset voltage at the sense electrodes.

    摘要： A pulse generator for an electrical control system of a machine having relatively movable parts such as for a programmed control system of a knitting machine. One machine part has a permanent magnet forming an air gap with at least one field plate in the air gap arranged such that the current therethrough depends on the nature of the magnetic field in the air gap. The other machine part has on it items to affect the nature of the magnetic field at the air gap upon relative movement of the machine parts, these items including a magnetically conductable body movable through the air gap and/or a magnetically conducting shunt body movable in the vicinity of the air gap. The magnetically conductable body may take the form of teeth on a soft iron comb, a soft iron plate with apertures, or separate soft iron pieces mounted separately for relative movement through the air gap.

    摘要： In a contactless switching device, a permanent magnet can be moved relative to a magnetic field dependent resistance positioned between return yoke parts. The longitudinal axis of the magnetic field dependent resistance is in the direction of the neutral zone of the permanent magnet. The return yoke parts face the poles of the permanent magnet over a large area. In order to remove the lines of force from the magnetic field dependent resistance, a part causing a magnetic short-circuit is inserted after the return yokes in the direction of movement of the permanent magnet. It is thereby possible to relieve the magnetic flux practically completely in the OFF position of the device with a relatively small distance of travel of the permanent magnet.

    摘要： Embodiments of the present invention provide a Hall effect device that includes a Hall effect region of a first semiconductive type, at least three contacts and a lateral conductive structure. The Hall effect region is formed in or on top of a substrate, wherein the substrate includes an isolation arrangement to isolate the Hall effect region in a lateral direction and in a depth direction from the substrate or other electronic devices in the substrate. The at least three contacts are arranged at a top of the Hall effect region to supply the Hall effect device with electric energy and to provide a Hall effect signal indicative of the magnetic field, wherein the Hall effect signal is generated in a portion of the Hall effect region defined by the at least three contacts. The lateral conductive structure is located between the Hall effect region and the isolation arrangement.
