Patent DE-3909588-A1 (DE)
Inventor: VOLKERT MATTHIAS DIPL ING
IPC: B60T8/1761
Filed: 1989-03-23
Abstract: Described is a process for determining the brake moment in the wheels of a braked vehicle. The brake pressure Pi acting on the wheels is measured continuously during a braking interval (t1 to t2) and the wheel speeds VRi measured at the beginning (VRi(t1)) and at the end (VRi(t2)) of the interval. From these measurements, the proportionality factor CP between brake torque and brake pressure can be determined using a given relationship. The brake torque values MBi in the wheels can then be calculated simply from the relationship (MBi = CP.Pi).

Inventor: BAUR GUENTER DR
IPC: G02F1/1343
Filed: 1990-01-09
Abstract: An electro-optical liquid crystal switch element comprises a liquid crystal layer and a re-orientation device for re-orienting the liquid crystal layer in an actual orientation in which the electro-optical liquid crystal switch element has a different light transmission. The re-orientation device comprises a field-generating structure for generating the electric field which causes the re-orientation. The electric field generated by the field-generating structure has a field component essentially parallel to the liquid crystal layer.
