The invention relates to a device for the pivoting connection of a wiper blade to a wiper arm of a windscreen wiper, comprising a connector element fixed to the wiper arm and a connector element fixed to a support element on the wiper blade, which supports a bearing element, forming a pivoting bearing with a bearing element on an adapter made from plastic. Traffic volume between switches is monitored. The control unit obtains any garbled character displayed on the display unit, determines whether the obtained garbled character matches a garbled character stored in the storage unit, if so, then the control unit controls the display unit to display an identifiable character in place of the garbled character. In one embodiment, the semiconductor includes a III-V material. The hybrid yoke also includes a steel portion having a yoke end and a shaft end, the shaft end for coupling to the driveshaft assembly and the yoke end for insertion into a second end of the cast iron portion.
