    Abstract: A magneto-elastically-based active force sensor, used with a tow coupling between a towed and a towing vehicle or a coupling between a vehicle body and a suspension of the vehicle, which outputs a signal useful for determining forces acting on the coupling. The outputted force information may be provided by processor-enabled embedded software algorithms that take inputs from the force sensor and other sensors, may be used by one or more vehicle systems during operating of the vehicle, such as engine, braking, stability, safety, and informational systems. The force sensor includes directionally-sensitive magnetic field sensing elements inside the sensor, and shielding may be used around the sensors to reduce the influence of external magnetic fields on the sensing elements. The force sensor may be used with different tow and vehicle weight sensing coupling devices installed on different types of automobile cars and trucks.

    Abstract: A sensor washing device that includes a washer housing that has a ring portion and a fluid source attachment. The fluid source attachment is configured to receive fluid. The ring portion has a main opening for receiving a detecting head of the sensor, an attachment side configured for mounting the washer housing, and a washing side configured to frame the detecting head of the sensor. The washing side is in fluid communication with the fluid source attachment. A plurality of nozzles are disposed in a transition portion of the washer housing between the ring portion and the fluid source attachment of the washer housing. The plurality of nozzles are configured to discharge fluid to the washer side radially inwardly towards the main opening for cleaning the detecting head of the sensor.

    Abstract: A speed sensor for a rotating shaft includes a plurality of magnetic portions on the shaft that output a magnetic field from each of the magnetic portions, wherein the magnetic portions are integrally formed in the shaft by magnetically polarizing the shaft material itself. At least one magnetic field sensor is positioned proximate to the shaft for detecting the magnetic field from each of the magnetic portions and for outputting a signal corresponding to the angular speed of the shaft as the shaft rotates. The signal is useful for calculating the angular speed of the shaft, and the calculated angular speed value is useful for things like adjusting the angular speed of the shaft, monitoring the performance of the system in which the shaft is used, and for other purposes.

    Abstract: A keyless entry system for an automobile includes a capacitive touch screen having at least one drive line and at least one sense line, the drive and sense lines defining a plurality of touch detection nodes. The touch screen is associated with an exterior surface of the automobile. A control circuit coupled to the touch screen is configured to detect proximity of a stimulus to the touch detection nodes. The control circuit provides a control output to a lock or latch controller when the control circuit determines that the stimulus has been placed proximate the touch detection nodes according to predetermined criteria.

    Abstract: Examples of a power peak shaving system are presented. In one example, the power peak shaving system includes a power directing circuit and a control circuit. The power directing circuit may direct power received from at least one of an alternating current (AC) supply voltage or an energy storage unit to generate an output voltage for a load. The control circuit may control the power directing circuit to supplement power received from the AC supply voltage with power received from the energy storage unit to supply power drawn by the load at the output voltage to prevent the power received from the AC supply voltage from exceeding a threshold level.

    Abstract: A system and method for creating one or more magnetically conditioned regions on a rotatable shaft or disk-shaped torque sensing element, wherein rotation noise produced by the element due to magnetic field variations is substantially negated. Upon magnetization of the torque sensing element, rotation noise produced by the magnetically conditioned region is measured. Adjustment factors are calculated based on the measured rotation noise, and the adjustment factors are used to adjust a magnetic field source during subsequent magnetization of the torque sensing element.
