Abstract: The invention relates to a lock-key system, including a key that is insertable into a key channel of a lock cylinder, and traceable by core pins or by locking elements that are displaceable in the cylinder core, wherein in case of a match, the cylinder core can be rotated by means of the inserted key. Lettering in the form of an impression and/or an embossment, serving as an identifier and including letters and/or numbers and/or symbols, is introduced into at least one lateral surface of the key shank and in case of a lateral profiling, into the lateral profiling. The lettering or individual letters, numbers, or the symbol or sub-areas thereof are traceable by core pins or locking elements having a correspondingly formed contact surface.

Abstract: The invention at hand concerns a method and a system for transmitting data in an optical transmission system. A measuring signal is generated having a wavelength which differs from the wavelengths of a data signal that includes the data to be transmitted. The measuring signal is coupled in the optical transmission system, reflected after passing through the transmission path and decoupled again. The coupled measuring signal is compared with the decoupled reflected measuring signal. By taking into account the comparison results, a compensation of the change of the data signal resulting from the dispersion in the fiber is performed in such a way that the data included in the data signal can be used.

Abstract: A lock-key system includes a key that can be inserted into a keyway of a lock cylinder, wherein said key is traceable by core pins or by locking elements which are movable in the cylinder core, wherein if there is a match, the cylinder core can be rotated by means of the inserted key. Lettering in the form of an impression and/or an embossment, serving as an identifier and including letters and/or numbers and/or symbols, is introduced into at least one lateral surface of the key shank—if a lateral profiling is present, into said lateral profiling. The lettering or individual letters, numbers, or the symbol or sub-areas thereof are traceable by core pins or locking elements having a correspondingly formed contact surface.

Abstract: The present arrangement provides a method for monitoring the performance reliability of a control unit and/or at least one sensor of a safety device for the protection of vehicle occupants, comprising the steps that a negative acceleration or velocity caused by an impact, in particular, be recorded; a value for the impact severity be derived from the recorded acceleration or velocity; and the value for the impact severity be compared to a predefined threshold value. If the value for the impact severity exceeds the predefined threshold value, an error-function signal will be output, which indicates that the proper functioning can no longer be ensured for the control unit and/or for at least one sensor. The present arrangement also relates to a diagnostic device for such a method.

Abstract: A method and a device for operating a vehicle allow a torque of the vehicle during operation of the vehicle to be measured. A torsional angle at at least one drive shaft of the vehicle is measured, and the torque transmitted via the at least one drive shaft is ascertained as a function of the measured torsional angle.

Abstract: A method and a device for deploying a restraint system, which avoids false deployments at the least possible expense by using an acceleration sensor arrangement that includes two sensitivity axes oriented in different directions. An acceleration measured with respect to one of the two sensitivity axes is used for a plausibility check of a deployment decision, which is determined from an acceleration measured with respect to the other sensitivity axis. A trigger signal is only generated if a deployment decision signal and a plausibility signal are present at the inputs of an AND logic circuit at the same time.

Abstract: The invention concerns a pharmaceutical preparation which contains one or several galacturonides as the active substance with a degree of polymerization of .gtoreq.2 and a degree of esterification of <20% optionally together with common pharmaceutical carriers, diluents, auxiliary substances and fillers as well as the use of this preparation to block the attachment of germs to mammalian cells.

Abstract: The invention is based on a method and system for regulation and/or control of an automobile chassis where between the vehicle body and at least one wheel there is at least one actuator actuated by actuation signals for exertion of forces between the vehicle and the at least one wheel. At least parts of the actuation signals are so formed that the vertical movements of the vehicle body will be damped inertially. According to the invention, at least parts of the actuation signals (Fij) are so formed that the damping takes place dependent on the magnitude of the vertical velocity (Zaij') of the vehicle body.
