    摘要： An apparatus that determines that a vehicle has moved comprises a shaft member, a pin configured to attach the shaft member to a backing plate via an opening in the shaft member that enables the shaft member to move in a direction along the length of the shaft member, to rotate about the pin, and to contact a surface external to the vehicle when the shaft member is in a first position. The apparatus also comprises a first alignment magnet that attracts the shaft member to the surface external to the vehicle and a first sensor that determines that the shaft member is in the first position. The apparatus further comprises a first holding magnet, a second holding magnet, and at least one sensor that indicates that the shaft member is in contact with the first holding magnet or the second holding magnet, each indicating a direction of movement.

    摘要： The invention relates to a method and a device for determining the rotational direction and/or the rotational speed of a rotating body on the basis of a sine signal (y) and a cosine signal (x) that are emitted by a sensor and can be assigned to the rotational direction and/or rotational speed of the rotating body. Said method comprises at least one of the following steps: capture of a sine signal (y0) and cosine signal (x0) that can be assigned to the rotational direction and/or rotational speed at a time t0; determination of a phase value φ0 from the sine signal (y0) and cosine signal (x0); capture of a sine signal (yi) and cosine signal (xi) that can be assigned to the rotational direction and/or rotational speed at a time ti; determination of phase values φi from the corresponding sine signals (yi) and cosine signals (xi); formation of phase differences Δφi from the phase values φi and the phase values φ0; and determination of the rotational direction and/or rotational speed ω from the phase differences Δφi on the basis of a Nonius method.

    摘要： A magnetic sensor apparatus (50) for sensing a magnet (52) is mounted to a rotating target (51), wherein the magnet spins with the rotating targe. The apparatus includes a substrate (56), a first (54) and a second (55) magnetoresistive sensor placed in a bridge configuration on the substrate to detect magnetic flux in a magnetic field created by said magnet, and to output analog bridge signals having an angular frequency. An interpolating integrated circuit (57) analyzes the analog bridge signals and converts the analog bridge signals into digital data. A processor (58) determines speed, position and direction of the rotating target from the digital data.
