摘要： A rotary position sensor measures the relative angular position (within a range of≦180°) of a housing or stator and a rotor. The housing carries a galvanomagnetic sensing element and is adapted for fixation to a relatively fixed portion of a host system. The rotor carrying a magnet is disposed for rotation about a fixed axis with respect to the stator and is interconnected to a relatively moving portion of the host system through intermediate linkage. The magnet is juxtaposed in substantially axial alignment with the galvanomagnetic sensing element for magnetic interaction therewith. The housing defines a cavity to receive potting material for encasing the galvanomagnetic sensing element and an adjacent buffer cavity interconnected by a weir, which diverts ant excess potting material into the buffer cavity.

摘要： A robust, low cost, compact and highly accurate rotary position sensor is disclosed for measuring the relative angular position (within a range ≦180°) of a housing or stator and a rotor. The housing carries a galvanomagnetic sensing element and is adapted for fixation to a relatively fixed portion of a host system. The rotor carrying a magnet is disposed for rotation about a fixed axis with respect to the stator and is interconnected to a relatively moving portion of the host system through intermediate linkage. The magnet is juxtaposed in substantially axial alignment with the galvanomagnetic sensing element for magnetic interaction therewith. The housing defines a cavity to receive potting material for encasing the galvanomagnetic sensing element and an adjacent buffer cavity interconnected by a weir, which diverts ant excess potting material into the buffer cavity.

摘要： A contactless latch engagement detector for a mechanical fastening system operating on the principle of magnetosensitivity. A magnetosensitive switch composed of a magnetosensitive device and at least one biasing magnet adjacent the magnetosensitive device are located in a buckle. Within or external to the buckle is an electronic circuit for driving the magnetosensitive device, and a flux bar composed of a ferromagnetic material having a high magnetic permeability is associated with a movable component of the system. In operation, the electronic circuit drives the magnetosensitive device, wherein its output is responsive to position of the flux bar relative to the magnetosensitive device. The flux bar moves responsive to position of a tongue within the buckle, whereby the fastened state of the mechanical (ie., seat belt) fastening system is detected when a predetermined output occurs.
