Patent DE-19732571-A1 (DE)
Title: Tapered piezo-actuator device for engineering esp automobile engineering, optics and control
Inventor: HOPF ROLF
IPC: H02N2/02
Filed: 1997-07-23
Abstract: The device can be of layered structure and narrows towards the side contg. a negative pole (1) in the form of a cone, pyramid etc. The device has a narrow actuation surface (5) which is adequate for its requirements. More ceramic presses on less ceramic from stack layer to stack layer in the direction of the actuator surface, which increases the displacement. The convergence of the field lines towards the negative pole also causes the displacement to increase.

Patent DE-19734112-A1 (DE)
Title: Traction control method for motor vehicles
Inventor: SCHMITT JOHANNES
IPC: B60K28/16
Filed: 1997-08-07
Abstract: The method is for traction control in cars, whereby, with the occurrence of an inclination for skidding of the driving wheel, the torque of a drive unit is reduced. A maximum transmittable torque is calculated by consideration of operating parameters of the car and its drive unit. With the onset of the traction control, the torque is reduced to the maximum transmittable torque. The maximum transmittable torque is dependent on a parameter showing the turning behaviour of the car when negotiating a curve. This parameter is the lateral acceleration. From this parameter is determined the curve-resisting torque which is taken care of when the maximum transmittable torque is formed.

Patent DE-19824013-A1 (DE)
Inventor: DABERKOW ANDREAS
IPC: B61G5/00
Filed: 1998-05-29
Abstract: The invention relates to a new lateral guidance vehicle system, especially a rail vehicle system, which consists of self-propelled base units that are respectively and essentially comprised of modules (5, 6) of mass-produced bus parts and substantially coupled without any traction force or pressure. Coupling is achieved by means of longitudinally elastic guide members or by dispensing with any form of mechanical coupling, whereby the latter option is achieved using means (21, 22, 23) that guide several base units (10, 16) in stacks. By dispensing with conventional mechanical couplings, the high degree of structural rigidity that is usually required for a rail vehicle in comparison with a road vehicle such as a bus is no longer needed. As a result, measures designed to adapt the construction of mass-produced bus parts to operate on rails are kept to a minimum.
