Patent DE-19601026-A1 (DE)
Title: Human eye movement recognition equipment for computer use by severely-disabled person
Inventor: PIPA GORDON
IPC: G06F3/01
Filed: 1996-01-13
Abstract: In a first stage, the line and the frame synchro-pulses are separated from the picture signal and processed according to the TTL standard, the rest of the equipment being synchronised to the resulting signal. The second stage consists of an A-D converter that digitises the picture information with a frequency of 1.565 MHz, 100 pixels per line. This information is fed alternately to the memories (SP1, SP2). Since both obtain their address from the same address bus, the pixel brightness of a pixel, at each point in time, is represented by a word (8 bytes) of the present and the previous picture. These words are separated from one another to supply a difference picture, recorded alternately in the memories (SP3, SP4), as controlled by the microcontroller (80C166).

Patent DE-19723261-A1 (DE)
Title: Valve timing gear for reciprocating piston engines and compressors
Inventor: LAPCEVIC NICOLA
IPC: F01L9/11
Filed: 1997-06-03
Abstract: The timing gear has mechanical or hydraulic transmission of valve opening force. A device (16,30,32,33) generates an RPM- dependant pretension force, which acts on the valve (3) against the force of the valve spring (5). The pretension force is large within the lower RPM range, and is small within the higher RPM range. The force is constant up to a middle RPM, and the quickly drops to zero. The pretension force acts directly, or via the intermediate end of the rocker arm (22) on the valve plunger (4), so that it reduces the force of the valve spring.
Patent DE-19725864-A1 (DE)
Inventor: RIVERO FELIPE JUAN CABEZON
IPC: F16F9/348
Filed: 1997-06-18
Abstract: A damper, eg of the twin tube type, comprises a piston 42, eg of sintered steel, having at least one deflectable disc 70, 82 which deflect to allow greater fluid flow through the compression or rebound passages 60, 62, thereby permitting higher piston speed in either the compression or rebound stroke. Discs 70 engage slidable bush 72 which, via coil spring 74, is allowed to slide axially when the discs 70 deflect so as to provide a blow-off characteristic. A nut 34 is threaded on to piston rod 18 to retain the bush 72 in position. The discs 70, 82 are supported by orifice discs 68, 80 which also deflect for high piston velocity and, together with discs 70, 82, are sized so as not to cover their respective passages 60, 62. A convex portion 86 on retaining washer 84 prevent damage when discs 82 deflect. Spring seat 73 and bushing 72 may also be made from sintered material.
