    摘要: A position sensor has a ring of a material of high permeability that is floated on a liquid within a hermetically sealed toroid, so as to hold the ring in a horizontal position. Exciting coils are distributed uniformly about the ring to enclose the cross section thereof, and receiving coils are distributed uniformly about the circumference of the ring.

    摘要: An electronic direction finder (10) includes a navigation receiver (28) and a compass (32) to generate a bearing signal that indicates that direction of a desired destination. The bearing signal is received by a display driver (34) which causes an electronic display (14) to generate a visible image of a rotatable pointer that points in the direction of the user's desired destination. Preferably, the display also shows an electronic compass card indicating the direction of north.

    摘要: A hand bearing compass comprises an electronic direction finding sensor fixed in a flat rectangular compass body. An actuating button causes the sensor to measure a magnetic bearing in dependence on the orientation of the compass body in a horizontal plane; measured bearings are stored in microprocessor memories for subsequent sequential recall to a display. To align the sensor horizontally in use the compass has longitudinal sights for visual alignment with a mark and a flat upper surface of the compass body for alignment with the horizon to facilitate levelling. Actuator and longitudinal sights are laterally spaced to avoid obscuring the latter, and arranged symmetrically about a median plane of the body so that use is possible in either hand.

    摘要: A fluxgate compass direction sensor in which a fluxgate is mounted relative to a receptacle by means of a flexible circuit. The fluxgate is also suspended in a liquid by means of a float. In use, if the receptacle tilts relative to the horizontal, the level of the liquid will move to retain a horizontal aspect and the float, being buoyant in the liquid, will retain the fluxgate in the horizontal plane. The flexible circuit acts to allow tilting of the float and fluxgate relative to the receptacle while retaining the fluxgate in lateral and directional alignment relative to the receptacle.

    摘要: A magnetic direction detecting apparatus has a magnetic sensor head composed of a magnetic core, an exciting coil wound around the core and a pair of detection coils diametrically wound around the core perpendicularly to each other; an oscillator for supplying a rectangular current wave of a single polarity to the exciting coil; and a switching gate openable synchronously with the rectangular wave for permitting only peaks of the same polarity to pass therethrough. The detection of a magnetic direction by using this apparatus does not suffer from restrictions in switching gate-opening timing.

    摘要: A drive guide system for an automotive vehicle indicates the remaining distance to a destination and the direction to the destination. In order to indicate the remaining distance and the direction in which to travel, travelling direction and travelling distance are detected. A direction sensor for detecting the terrestrial magnetic field is employed in the drive guide system. The direction sensor can be easily influenced by background noises in its surroundings. The background noise thus affects the detection of the direction of the terrestrial magnetism and thus causes errors in the calculation of the remaining distance and the direction to travel. Therefore, the variation of the background noise is sequentially monitored to detect the magnitude of the background noise affecting the detection of the direction, and when the variation exceeds acceptable limits, an error signal is produced.

The traveling direction of a moving object can be detected as a precise geographic azimuth even when the moving object lies in a place subject to the magnetic disturbance.
