Patent DE-3800371-A1 (DE)
Title: Method for the braking of a vehicle
Inventor: STRENZKE HILMAR DR ING
IPC: F16H61/42
Filed: 1988-01-08
Abstract: A vehicle with an engine and a hydrostatic transmission comprising adjustable hydraulic machines can be braked utilising the brake torque of the engine in that an electronic component constantly adjusts the hydraulic machines. In order to prevent over-revving of the engine during braking of the vehicle without the need for manual intervention on the part of the driver, it is proposed that, when an engine speed limit is exceeded, the electronic assembly bring the hydraulic machines into a setting which relieves the engine and that the pressure present in the hydrostatic transmission be reduced by way of valves until the engine speed is below the limit value. Then the hydraulic machines are again adjusted utilising the brake torque. This process is repeated until the brake torque of the engine is sufficient to ensure vehicle braking without over-revving of the engine.

Title: Data transmission device with differential phase modulation and two operating sequences
Inventor: AXINTEANU LUCIAN DIPL ING
IPC: H04L12/403
Filed: 1988-05-27
Abstract: This data transmission device exploits the advantage of differential phase modulation in that the operating frequency is the same as the transmission frequency. The up to 240 subscribers are polled once only by means of a short telegram from the data collector in sequence A. Only those subscribers who identify a change in their peripherals send a short reply (5 bits) in time division multiplexing. The data collector thereby identifies which of the 240 subscribers is indicating a change in condition. Only these subscribers are polled in sequence B. In response, they notify the data collector of the change. This method enables data communication in >>real time<<.
