The shaft includes one or more sets of marks. A set of the one or more sets of marks includes at least one mark. The at least one mark corresponds to at least one shaft position where the power transmission belt is tensioned a pre-determined amount via an extension force generated by an elongation of the power transmission belt. The shaft is moveable between the zero position and the at least one shaft position.

The system is characterized in that, in order to increase the intensity of light reflected towards the camera, said target is cylindrical, realized in material reflecting to the frequency of the light emitted by said laser and positioned with its axis parallel to the sliding bow axis, in a position where it is lighted by said laser and framed by said camera.

A tie down anchor tension monitoring system includes a tension level monitoring module and at least one tie down anchoring point integrated into a cargo carrying space configured for connecting to a free end of a cargo tie down strap. The system further includes at least one tension level monitoring sensor integrated with the at least one tie down anchoring point, wherein the at least one tension monitoring sensor is configured to output a signal to the tension monitoring module that is indicative of a tension level of the cargo tie down strap.

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.
