  • Patent number: 5754042
    Abstract: An apparatus for detecting precise angular positions of a rotating object. Two magnetoresistors (MRs) are positioned adjacent a target wheel attached to the rotating object, the target wheel having at least one element of finite length. Each MR is responsive to the passage of at least one of the elements as the target wheel is rotated, generating an analog signal with signal transitions between two voltage levels at the passage of the element's leading and trailing edges. The MRs are positioned relative to the elements such that their signals are phase shifted with respect to one another, resulting in time overlapping signals which intersect at a precise angular positions of the target wheel.

  • Patent number: 5668740
    Abstract: A method for detecting a rough road surface upon which a vehicle is travelling, such detection being utilized by a crash sensing system for improving its immunity to inadvertent deployment during minor crash incidents. The onset of a crash event is sensed by an on-board accelerometer when the detected vehicle deceleration exceeds a predetermined deceleration threshold value. A rough road measurement is calculated as a function of the vehicle deceleration data and compared to a threshold boundary curve. A value of the rough road measurement exceeding the boundary curve is indicative of a rough road event.

  • Patent number: 5606254
    Abstract: A variable reluctance sensor for sensing the rotational speed of a target wheel having teeth, separated by slots, angularly positioned along its periphery is comprised of an elongated core interposed between two permanent magnets which generate additive magnetic flux passing longitudinally through the elongated core. This additive flux is, however, opposed by a longitudinal flux developed by the opposing ends of the permanent magnets. In the absence of surrounding ferromagnetic material, the magnitudes of the opposing longitudinal flux components are essentially equal, resulting in no net longitudinal component of magnetic flux. The elongated core and permanent magnets are encircled by a multi-turn electrical coil which is wound transversely about a longitudinal dimension. A portion of the elongated core and permanent magnets extending beyond the electrical coil are positioned adjacent the periphery of the target wheel and define an air gap therebetween.

  • Patent number: 5579230
    Abstract: Before braking occurs the speed of non-driven wheels is monitored and averaged to determine vehicle speed and an integrator is initialized with that speed. Acceleration is periodically calculated from the vehicle speed, stored in a ring buffer and averaged. The output of a chassis accelerometer is also sampled during the same periods and stored in a similar ring buffer and averaged. Accelerometer bias due to slope or drift is determined as the difference of the two averaged accelerations. The noise level of the accelerometer bias is determined by filtering and rectification. After braking occurs, the accelerometer output is corrected by subtracting the bias and the noise and is then used to continuously update the integrator output to provide an estimate of vehicle speed during braking.

  • Patent number: 5481884
    Abstract: In a refrigeration system, an apparatus and method for providing low refrigerant charge detection before and during compressor operation. For detection before compressor operation, a very low refrigerant charge condition is indicated if the measured refrigerant pressure at the inlet of the compressor is too low based on a comparison of the measured pressure and a reference pressure related to the saturation pressure at the measured ambient temperature. If a low refrigerant charge condition is detected, the compressor may be inhibited from operating. If the system is stable with compressor non-operation, a warning also occurs. While the compressor is operating, a moderately low refrigerant charge condition is detected if the measured refrigerant temperature at the inlet of the compressor is too high based on a comparison of the measured temperature and a reference temperature related to the saturation temperature of the refrigerant for the measured refrigerant pressure.
