Patent DE-19727004-A1 (DE)
Title: Combustion failure recognition method for IC engines
Inventor: ROTTLER JUERGEN DR
IPC: F02D45/00
Filed: 1997-06-25
Abstract: The failure recognition method involves detecting the ion current signal over a specified time interval from the discharge of the spark plug, then integrated with respect to time. The maximum of the integrated signal is then compared with a speed-dependent and load-dependent threshold, whereby an error signal is produced if the threshold is not exceeded. The integration is undertaken in weighted fashion with a time weighting function matched to previously detected ion current signals. The offset of the ion current signal is detected and eliminated from the weighted integrated signal.

Title: Magnetic length measuring system for absolute position measurement
Inventor: DETTMANN FRITZ DR
IPC: G01D5/245
Filed: 1997-07-09
Abstract: The system contains at least one magnetic code track (6) on a scale (5) and sensors for scanning the magnetic fields produced above the code track. One binary condition of a code element (1) in the code track is represented through a uniform magnetization, and the other binary condition through a change of the magnetization direction. Magneto-resistive sensors (2) are provided, whose sensor plane is formed through the normal (N) of the scale surface and the measuring direction (x). The output signal of the sensors is approximately given by the equation Ua = U0 * cos(2 *  phi ), where  phi  is the angle between the magnetic field direction and the normal of the scale surface, and U0 is a constant amplitude. A certain amount of successive code elements forms preferably a code word, and two magneto-resistive sensors are preferably available for each code element.

Patent DE-19746641-A1 (DE)
Inventor: RAMM PETER
IPC: H01L23/58
Filed: 1997-10-22
Abstract: The present invention relates to a method for producing a metallised-circuit structure for preventing product piracy and manipulation as well as to a semi-conductor component produced according to this method and to the use of said semi-conductor component in a chip card. This method can be implemented using standardised semi-conductor techniques which are compatible with CMOS circuits, wherein the purpose of said method is to forestall the use of the so-called reverse engineering for acquiring foreign technological know-how or for reading and/or manipulating information stored in said component. According to the method of the present invention, it is further possible to produce a semi-conductor component which is protected against the influence of the environment. This method comprises processing the component layer in the substrate (1) and interrupting said processing immediately before obtaining a metallisation complex. The component substrate (1) thus obtained is assembled by applying its front side against the front side of a manipulation substrate (6), said component substrate (1) being then made thinner from the rear side. Contact holes (9) are then etched during a corresponding lithographic stage through the remaining thin layer of the component substrate, wherein said holes stop at the level of the areas to be brought into contact and are metallised so as to form electric contacts relative to the components.

Patent DE-19835803-A1 (DE)
Inventor: GLEIM GUENTER
IPC: H04N9/28
Filed: 1998-08-07
Abstract: The invention relates to a method for convergence correction in a television receiver, in particular in a projection colour television receiver. Convergence devices serve to correct parameters in the raster deflection, for example the correction of north/south and east/west distortions and pin-cushioned distortions of non-linearities in the deflection, and other geometric errors in the horizontal and vertical directions. The correction of the deflection parameters is undertaken with the aid of digital correction values which are stored in a convergence circuit. Convergence coils generate a magnetic field corresponding to the digital correction values. The current flowing in the convergence coil is regulated to a desired value by means of a measuring shunt and a feedback loop. Series resistances, e.g. due to resistance of conductor tracks can cause the reference potential of the measuring shunt to vary. This leads in the final analysis to defective regulation of the convergence current. The invention specifies a method in which the said difficulties no longer occur in a troublesome fashion. The method according to the invention is based essentially on the fact that the crosstalking of one convergence channel into the other convergence channel is determined quantitatively. The measured values thus obtained are taken into account in a subsequent regulation of the convergence currents, with the result that overall an exact regulation of the convergence currents is obtained again. Finally, the invention suggests an apparatus for convergence correction in a colour television receiver.
