The shaft extends through the ring and the first ball part, and through and beyond the second ball part to a second end, at which the shaft is connected to the bumper by a joint. At least one ball part is displaceable along the shaft. The spring extends around the shaft between the second ball part and a spring connector, and pretensionedly presses the first and second ball parts against the ring.

This will also realign the sensor, ensuring a longer effective lifetime of the sensor and thus of the safety of the vehicle.

US11054714B2	Electro-active lenses with raised resistive bridges Resistive bridges can connect many ring electrodes in an electro-active lens with a relatively small number of buss lines. These resistors are usually large to prevent excessive current consumption.

Placing the ring electrodes and resistors on layers separated by an insulator makes it possible for the ring electrodes to be closer together and continuous with resistance high enough to limit current consumption.
