Abstract: A device and a method are provided for the analysis of a sample plate on which at least two material samples are situated. In the method, one impedance spectrum is measured for each of the material samples. As a function of the respectively measured impedance spectrum, a configuration of a circuit equivalent is determined which includes at least one electronic component. Then, for an error minimization computation, starting values for the components of the respective circuit equivalents are determined. In the error minimization computation, a theoretical impedance spectrum is calculated for at least one of the material samples, based on the impedance spectrum measured for the material sample, as well as the starting values for the components of the respective circuit equivalent, and fit values are determined for the components of the respective circuit equivalent.

Abstract: A method of identifying a living being includes using a time-of-flight sensor to determine a location of a face of the living being.

Abstract: A wrench for tamper switch installation for use with a tamper switch arrangement including an enclosure containing a tamper switch assembly having a mounting rail for assembling the tamper switch assembly to a security system enclosure. The wrench may be capable of holding two separate nuts and have cooperating mating structure to slidably mate with the mounting rail of the tamper switch arrangement. The nuts may be frictionally-fitted into the wrench, after which the wrench is slidably moved onto the mounting rail until the nuts line up with two throughbores in the mounting rail. Two screws or bolts are then inserted through a surface of the security system enclosure and traverse the throughbores in the mounting rail. The screws or bolts then threadably engage the two nuts disposed within the wrench and are threaded therethrough via rotation with a suitable instrument, e.g., a screwdriver, located outside of the security system enclosure.

Abstract: Vehicle operation is controllable and/or regulatable by specifying a driver request describing a setpoint rotational speed or a setpoint torque via an accelerator pedal, detecting the instantaneous position of the accelerator pedal and controlling and/or regulating the internal combustion engine such that the setpoint rotational speed or setpoint torque is achievable. To provide for a sustained-action brake to be easily operated in the vehicle, and increase the vehicle's range of use, one of possible braking actions of the vehicle is specified by selecting a determined position of the pedal. As a function of an instantaneously detected position of the accelerator pedal, the operation of the vehicle is controlled and/or regulated such that braking power specified via the accelerator pedal is achieved. A variation in the braking power specified via the accelerator pedal is also converted as continuously as possible to a corresponding braking power by suitably activating additional components or devices.

Abstract: The invention relates to a windscreen wiper system, in particular for a motor vehicle, comprising at least one wiper arm provided with an elastic blade (21) and a fixing element (60). The known wiper arms comprise a tension spring which presses the wiper blade against a pane along with the windscreen wiper operation and maintains said wiper blade in a folded position with respect to the pane when the wiper blade is changed. Said wiper arms require a relatively important number of components and, for this reason, are relatively expensive. The aim of said invention is to make it possible to produce the windscreen wiper system in a more economical manner. For this purpose, the inventive elastic blade (21) is arranged in such a way that it is pivotable about the fixing element (60).
