Abstract: A sensor system for a vehicle, including a first sensor that detects at least one collision-relevant physical variable and outputs at least one corresponding first sensor signal, and at least one second sensor that, independently of the first sensor, detects at least one collision-relevant physical variable and outputs at least one corresponding second sensor signal, and an evaluation and control unit that receives the at least one first sensor signal and the at least one second sensor signal and evaluates them for the collision detection. A method is also described for monitoring a sensor. The evaluation and control unit uses at least one second comparison signal that is based on the at least one second sensor signal of the at least one second sensor to monitor the first sensor.

Abstract: A hybrid energy storage system includes at least one first energy store and at least a second energy store, each with a nominal energy flow at least in one direction, wherein the energy stores exchange electrical energy with one another and/or with at least one external energy source and/or energy sink via electro-physical energy flows, using at least one control circuit. The control circuit operates the energy sink using at least one boost converter, which has at least one electronic switch, and/or a buck converter in the event of a required energy flow of the energy sink which is higher than the nominal energy flow of the second energy store, with an energy flow of the first energy store, while the second energy store supplies an energy flow from zero up to a constant energy flow which corresponds at maximum to the nominal energy flow of the second energy store.

Abstract: Methods for producing cellulose articles having controlled release of active ingredient include dispersing pulp in aqueous direct solvent for cellulose to form a slurry. Organically modified or ion-exchange-activated phyllosilicate is homogenized in a direct solvent for cellulose with exfoliation by shearing, then mixed with the slurried pulp. A mixture of active ingredient and a lipophilic matrix material or a water-in-oil (“W/O”) emulsion containing active ingredient is stabilized with thickener, converted into a gel-like paste, and mixed with the slurried pulp. Water is stripped from the mixture until all cellulose is dissolved, the mixture is formed into shaped articles, and dried. Exemplary active ingredients include cosmetic active ingredients, fat-soluble vitamins or apolar plant extracts. Domains of active ingredient and matrix material or emulsion containing active ingredient are present as fine divisions within the inventive articles.

Abstract: A method is described for operating an injector, in particular an injector of an injection system of an internal combustion engine, the injector including a piezoelectric actuator that is connected to a valve needle via a coupling element, an electric voltage being applied to the piezoelectric actuator, resulting in an increase and/or decrease in the length of the piezoelectric actuator, a holding voltage being applied to the piezoelectric actuator when the injector is closed. The voltage of the piezoelectric actuator is brought to the holding voltage by a recharge sequence.

Abstract: A method for generating a triggering signal for a passenger protection device in which sensor data are detected and analyzed for accident classification, and to a corresponding device. To determine a relative accident velocity, signals of at least two measuring points offset by a predefined distance in the x direction are analyzed, and the time interval between a crash signal detected by a first sensor at a first measuring point and a crash signal detected by another sensor at another measuring point is determined.
