Title: Dynamic verification of handwritten character by weighting of strokes
Inventor: WIRTZ BRIGITTE
IPC: G07C9/00
Filed: 1995-03-29
Granted: 1996-10-17
Abstract: Movement data (BEW) of the pen are detected on a tablet and normalised (N). The normalised movement data (NBEW) is compared (VER) with a reference pattern or signature (REF) held in a database (RDB). Dynamic programming is used in the comparison to obtain a measure of the correspondence of the shape parameters (MFORM) and dynamic parameters (MDYN).  The min. distance between strokes is computed and a combination of at least two normalised movement parameters is chosen, one of which describes the time dependence of pen position.

Title: Function module replacement circuit
Inventor: SCHALAMON FRIEDRICH
IPC: H03K17/76
Filed: 1995-08-04
Granted: 1996-12-19
Abstract: The replacement circuit comprises a number of uniform functional units (FE1, FE2,...), a switch control unit (KOM) and a replacement unit (EFE), coupled to the control unit. Each functional unit comprises an input selector (EUS1), that switches an input signal (ES1,ES2) either to the control unit or to the functional unit. An output selector (AUS1, ... ) switches either an output signal from the functional unit ( AS1,...) or an replacement output signal from the replacement unit, coupled to the control unit (EAS), to the output of the respective functional unit. A passive combiner (VK1) gathers all the input signals (E1 to E8) and provides one signal to the input of the replacement unit, and a passive distributor (VK2) switches the output of the replacement unit to the output selectors (AUS1, AUS2, ...). A switching controller (SKL) is coupled to each function unit, that isolates a defect functional unit and replaces it by switching in the replacement unit, based on error messages. The passive combiner is comprised of PIN-diode switches that lead from the number of inputs to a common node via decoupling resistors, and/or the passive distributor is comprised of PIN-diode switches that lead from a common node to a number of outputs.

Title: Magnetic field sensor for automotive instrumentation applications
Inventor: GRILL THOMAS DIPL ING
IPC: G01R33/02
Filed: 1995-10-18
Granted: 1997-03-06
Abstract: The aim is to improve a magnetic field sensor consisting of a cylinder coil (2) with a core of amorphous ferromagnetic metal. The inductance of the coil (2) can be controlled by the earth magnetic field HE and forms part of an L.C. oscillator (1). To determine the operating range of the oscillator (1), the amorphous metallic core of the coil (2) is pre-magnetised. To achieve the desired improvement, it is proposed that an adjusting device should be provided to smooth out fluctuations from a target value fsoll in the oscillator frequency fOsz caused by the action of the magnetic field HE on the oscillator coil (2). This is done by allowing another adjustable magnetic field to influence the inductance (2) of the oscillator (1): the adjustable magnetic field is generated by a second coil (3) in the form of a compensating coil and the current flux (1) through the second coil (3) is controlled by the adjusting device in such a way that the magnetic field generated by the second coil (3) compensates for the action of the field HE on the first coil (2); and a control logic element (8) changes the polarity of the current flux (1) through the compensating coil (3) at a rate which matches the fluctuations with time of the field HE by synchronous actuation of switches (9a) and (9b). Where the field HE is present for both current directions, the respective compensating currents I1 and I2 are measured and the difference (I1-I2) determined as the variable proportional to the field strength of the field HE.
