Patent DE-4221435-A1 (DE)
Inventor: RITTER HARTMUT DIPL PHYS
IPC: G01R31/3185
Filed: 1992-06-30
Abstract: A clock-controlled boundary-scan device integrated on an electronic chip exhibits a shift register of register elements. These register elements in each case form a signal path for connecting a digital circuit input/output of a chip-internal circuit arrangement to a chip terminal and in each case a shifting path for connection to adjacent register elements. In the scan device, an operating mode can be activated in which at least one sequence of n register elements (BSC) forms a shift register with feedback. This shift register with feedback is used for generating an n-bit-long bit pattern sequence, which can be output to chip terminals (BA) or for forming a signature from an n-bit-long bit pattern sequence supplied to the register elements at the chip-terminal end. <IMAGE>

Patent DE-4310415-A1 (DE)
Inventor: WISKIRCHEN MICHAEL
IPC: F16K31/40
Filed: 1993-03-31
Abstract: The proposal is for an electromagnetic valve, especially for pressurised water lines, which permits the use of low-power exciting coils (2). To this end a seal (16) is movable coupled to the armature (9) via a shaft (13). Thus the armature (9) can move when the valve is attracted without load in a zone in which the force developed by the magnetic field is great and hence a low-power exciting coil (2) suffices to open the valve against the pressure in the line.
