Abstract: A sports rebound wall is provided that includes: a rebound surface, at least one target area formed in the rebound surface, and a resistive matrix sensor formed on, or embedded in, the target area. The matrix sensor includes a first array of substantially parallel conductive tracks and a second array of substantially parallel conductive tracks. The first array and the second array are spaced apart from one another. The rebound wall has a matrix sensor that is capable of providing information about the force, location and timing at which the target area of the sports rebound wall is impacted. This is made possible by the specific construction of the matrix sensor.

Abstract: A capacitive detection device (20) for a vehicle comprises a sensing electrode (26) for generating an oscillatory electric field in a detection space and a shielding electrode (28) arranged on a side of the sensing electrode turned away from the detection space. The capacitive detection device comprises a circuit ground and a ground connector for connecting the circuit ground to chassis ground of the vehicle. At least one shunt capacitor is connected between circuit ground and the shielding electrode. The at least one shunt capacitor has a capacitance at least 25 times higher than the capacitance between the shielding electrode and the chassis ground of the vehicle.
