Title: Controlling current supply to electrical load in vehicle - supplies rated voltage for only short time to ensure or keep exact operating function
Inventor: EISERMANN GUENTER
IPC: B60R16/02
Filed: 1990-08-18
Abstract: The 100 percent switched on duration user load (1) is assigned an electronic circuit (2), so that the user load (1) is supplied only for a short time, in order to set with certainty or to maintain its precise operating function, is supplied with a rated or operating voltage (Umax). The supply voltage to the 100 percent switched on user load (1) is then lowered to an essentially lower level, but still reliably setting the remaining or the holding voltage level (URest) for the operation function of the 100 percent switched on load user (1). The time span during which the user load (1) is supplied with a rated or operating voltage (Umax) for the certain setting of its operating function amounts to about 100 ms. USE/ADVANTAGE - For controlling current supply to electric user with 100 percent switched on duration in DC system. Operation is controlled uncritically and temp. loading controlled.

Title: Data transmission procedure - using inaccuracies in data content occurring through scanning of data source as modulation content for transmission of data
Inventor: KOLLER ROMAN
IPC: H04L9/00
Filed: 1992-09-13
