Abstract: The invention relates to the monitoring of products by means of active radio tags. According to the invention, packagings of products are provided with an active radio tag that detects at least one environmental condition and/or at least one packaging state, and which emits a signal at time intervals, which provides information about a unique identifier and at least one state in which the respective product is found. The signal is picked up by a receiver that extracts the unique identifier and the state information and transmits same together with location information to an external server.

Abstract: An internal combustion engine has a high-pressure exhaust-gas recirculation line and a low-pressure exhaust-gas recirculation line with a low-pressure exhaust-gas recirculation valve. The low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system downstream of a turbine of an exhaust-gas turbocharger and opens into a fresh-air system upstream of a compressor of the exhaust-gas turbocharger. An exhaust-gas flap is disposed in the exhaust-gas system downstream from where the low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system. At least one pressure sensor is disposed in the low-pressure exhaust-gas recirculation line and configured such that the at least one pressure sensor determines a pressure difference in the low-pressure exhaust-gas recirculation line between a point upstream of the low-pressure exhaust-gas recirculation valve and a point downstream of the low-pressure exhaust-gas recirculation valve.

Abstract: Packaging material, for example, for tube bodies, bearing a hologram-like image. The packaging material is formed for a multilayered material with a layer structure containing: (a) a completely or partially embossed metal foil or metallized plastic film, and (b) on top, at least in specific areas, a transparent single or multilayered plastic layer. The plastic layer (b) forms the outer lying layer of the packaging. The embossed image on the metal foil (a) is visible through the transparent areas of the plastic layer (b). The packaging material gives the observer the impression of viewing a hologram-like image.

Abstract: The present invention is directed to a circuit arrangement for adjustment of the triggering point of the keys in an inductive keyboard. The keyboard consists essentially of a printed circuit board designed in a matrix-like manner, comprising coils superimposed upon each other, into which a ferrite pin plunges when a key is actuated. By the cooperation of a pulse generator with a current switch which can be influenced through control lines, said cooperation being controllable by a microcomputer, a current pulse is coupled from one coil to another coil and is recognized as a readout signal by a controllable readout amplifier and is conducted further to a central unit. The adjustment of the triggering point of the keys is accomplished by varying the steepness of the driving current pulse, for example, by means of a blocking time duration in the charging of a capacitor determined only once, which durations are stored in a table of values, or it is derived from the fundamental interlinked signals of the keys.
