    Abstract: A magnetic torque sensing device having a torque transferring member with a magnetoelastically active region. The magnetoelastically active region has oppositely polarized magnetically conditioned regions with initial directions of magnetization that are perpendicular to the sensitive directions of magnetic field sensor pairs placed proximate to the magnetically active region. Magnetic field sensors are specially positioned in relation to the torque-transferring member to accurately measure torque while providing improved RSU performance and reducing the detrimental effects of compassing. The torque sensing devices are incorporated on vehicle drive train components, including differential components, transfer case components, transmission components, and others, including on power transmission shafts, half-shafts, and wheels, and output signals representing characteristics of the vehicle are processed in algorithms to provide useful output information for controlling actions of the vehicle.

    Abstract: A luminous flux collector comprises a housing, a wide-angle light capturing device and an optical collimating device, arranged around a longitudinal axis. The housing surrounds and protects the wide-angle light capturing device and the optical collimating device. The housing also provides structural support to hold the other elements in position. The wide-angle light capturing device can include a receptacle for receiving a light source, and the wide-angle light capturing device collects light with a spread angle of at least 120 degrees from the light source. The wide-angle light capturing device is disposed within a proximal end of the housing along the longitudinal axis. The optical collimating device extends from the wide-angle light capturing device to a distal end of the housing along the longitudinal axis.

    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: An electronic accelerometer-based tilt switch for vehicles is capable of controlling the state of an electrical circuit according to the angle of inclination of the switch, for example to control power to a lamp. The switch includes a housing mountable to a vehicle member that is movable between a first position and a second position. When the vehicle member is in the first position it is at a predetermined angle of inclination versus when the vehicle member is in the second position. The housing may include an accelerometer and a control circuit to receive signals from the accelerometer indicative of an instant angle of inclination of the vehicle member and to switch the state of the electrical circuit between first and second states corresponding to first and second positions of the vehicle member.
