Abstract
A system for monitoring a load for displacement on a vehicle, comprising a support structure adapted to be fixed to the vehicle. A sensor is supported by the support structure. The sensor is positioned with respect to the load so as to detect a displacement of the load with respect to the vehicle. An interface receives and processes signals from the sensor and to a user of the vehicle.
Claims12
A sensor for detecting displacement of a load in a freight vehicle, comprising:
- a fixed portion adapted to be secured to the freight vehicle in a given position with respect to the load;
- a movable portion adapted to be releasably connected to the load so as to be displaced by displacements of the load;
- a joint interconnecting the fixed portion to the movable portion so as to allow relative motion between the fixed portion and the movable portion;
- and
- a signal generator connected to any of the fixed portion, the movable portion and the joint so as to detect relative motion between the fixed portion and the movable portion so as to signal a displacement of the load.

A method for signaling a displacement of a load in a freight vehicle, comprising the steps of:
- providing a sensor positioned with respect to the load such that the sensor is triggered by a displacement of the load with respect to the freight vehicle;
- obtaining a signal from the sensor for the displacement;
- and
- sending the signal to a driver of the freight vehicle to indicate that the load has been subjected to a displacement.
