Abstract: An unattended sensor is provided for use in a surveillance system. The sensor is generally comprised of: a detector; a signal processor; a radio transceiver; a power source; and a controller which configures the sensor in either a sensor mode or a relay mode. When configured in the sensor mode, the detector and signal processor are operational and the transceiver is non-operational. When configured in the relay mode, the transceiver is operational but the detector and signal processor are non-operational. In an alternative approach, the detector and the signal process may remain operational in the relay mode.

Abstract: A process for forming at least one local contact area of a substrate of an electrical component for contacting the contact area with a connector, in which the substrate, on the contact side, is provided with a sintered porous metal layer. To make available a mechanically durable, electrically faultless solderable contact area, it is proposed that the porous layer be compacted and/or removed in the contact area to be formed.

Abstract: A method for regulating a fuel injection system of an internal combustion engine, wherein the fuel injection system includes a high-pressure pump which is associated with a quantity control valve having a solenoid valve electromagnetically operable by a coil for supplying fuel, the quantity control valve regulating the fuel quantity pumped by the high pressure pump and the coil of the solenoid valve being energized according to a setpoint current value in order to close the valve for supplying fuel to the high-pressure pump; when the solenoid valve closes, the setpoint current value is reduced from a first current setpoint value to a second current setpoint value so that an emission of audible noise generated when the solenoid valve closes during operation of the internal combustion engine is at least partially reduced.

Abstract: A method for producing an electrically conducting metal contact on a semiconductor component having a coating on the surface of a semiconductor substrate. In order to keep transfer resistances low while maintaining good mechanical strength, the invention proposes applying a particle-containing fluid onto the coating, where the particles contain at least metal particles and glass frits, curing the fluid while simultaneously forming metal areas in the substrate through heat treatment, removing the cured fluid and the areas of the coating covered by the fluid, and depositing, for the purposes of forming the contact without using intermediate layers, electrically conducting material from a solution onto areas of the semiconductor component in which the coating is removed while at the same time conductively connecting the metal areas present in said areas on the substrate.
