WO2004048912 A UPAB: 20040702 NOVELTY - System to control and/or monitor and/or regulate a vehicle or aircraft has a sensor to receive an operating condition value, and a signal processing unit. The sensor is formed by an amorphous carbon layer with piezoresistive characteristics. The sensor can measure force components in different directions (x,y) and can determine a torque. DETAILED DESCRIPTION - System to control and/or monitor and/or regulate a vehicle or aircraft has a sensor to receive an operating condition value, and a signal processing unit. The sensor is formed by an amorphous carbon layer with piezoresistive characteristics. The sensor can measure force components in different directions (x,y) and can determine a torque. Two sensors (1,1,2,2) are used for each direction, so that a constant load in the x-direction generates an identical signal at both sensors, and the same applies for the sensors in the y-direction. A difference at the y-sensors shows a torque around the y-axis which can be determined from the force difference and the known gap. USE - For use on or in a rail vehicle and the permanent way rail, to register the load distribution over a load-carrying surface or an aircraft cargo hold surface, the center of gravity of a load, the force distribution at vehicle wheel mountings, the acceleration or wheel slip or imbalance of vehicle wheel or low tire pressures, the load or load distribution at a vehicle seat, the load or its distribution at an airbag control, the forces on a motor suspension etc. ADVANTAGE - The novel vehicle/aircraft sensor system gives increased security with improved comfort. It can also give information about loads being carried. The sensor can be integrated into the component being monitored without joints, distortion, or constructive modifications.
