Becker Helmut Dr: Proximity sensor.. Standard Elektrik Lorenz, September 2, 1987: EP0234458-A2 (3 worldwide citation)

The proximity sensor which responds to the approach or removal of a magnetisable object is characterised by the fact that it exhibits a substrate (3) having at least one magnetic-field-dependent resistance (4) applied thereto on the sensor side (2) and the magnetic-field- dependent resistance or res ...

Becker Helmut Dr, Kiessling Armin Gottfried: Apparatus for the determination of magnetic domains.. Sel Alcatel, Alcatel, September 6, 1989: EP0331135-A2 (2 worldwide citation)

Ein magnetisches Feld kann dadurch festgestellt werden, dass magnetisierte Bereiche an einem magnetfeldabhängigen Widerstand vorbeibewegt werden. Auf das sich dabei ändernde Magnetfeld spricht der magnetfeldabhängige Widerstand an. Die einwandfreie Detektion von Magnetfeldern ist durch die Breite de ...

Becker Helmut Dr: Device with at least one magnetoresistance in a housing.. Standard Elektrik Lorenz, Alcatel, July 19, 1989: EP0324105-A2

In this device, the object to be detected and moved past the magnetic-field-dependent resistor carries a permanent magnet, the stray field of which, when moved past the magnetic-field-dependent resistor, changes its resistance value. To achieve a high sensitivity, the distance between magnetic-field ...
