    摘要: An optical detection device having a light detection device and a light emission device is arranged such that the light detection side of the light detection device is optically coupled to a light emission side of a light source array of the light emission device via an examination region. The light detection device generates an electrical signal n response to light that reaches the light detection side. The light source array includes a plurality of separately actuatable electric light sources which are arranged in a matrix structure or two dimensional geometric arrangement. The object to be examined can be arranged in a desired fashion, and the light emitted by the light sources radiates via the examination region on the light detection side of the light detection device. An optical reduction is system is arranged in the beam path from the light emission side to the examination region and is configured to demagnify the light pattern which is emitted by the light sources. Thus, the examination region is irradiated by a light pattern that has been demagnified with respect to the light pattern emitted.

    摘要: The invention relates to a power circuit breaker that is suitable for switching electrical voltages. The power circuit breaker according to the invention comprises two main electrodes, to each of which a respective pole of the voltage to be switched can be connected. During the switching process, at least one of said main electrodes follows a switching path. The power circuit breaker is characterized in that secondary electrodes are additionally provided, which protrude into the vicinity of the switching path and are designed and arranged in such a way that arcs can be produced (a) between the main electrodes and the secondary electrodes and (b) between the individual secondary electrodes during the switching process. The power circuit breaker according to the invention can be advantageously used in vehicles and in ultra-high-voltage AC and HVDC (high-voltage direct current) transmission systems and causes arcs to be extinguished as early as possible during the switching process.

    摘要: The present invention relates to a method and a suitable apparatus for determining the state of a rechargeable battery and for checking contact resistances in a battery system. According to the invention, an impedance curve is determined using signals at different frequencies and a value for an area, which results from the impedance curve, is then calculated from a predetermined threshold value and an x axis. The value for the area is a measure of the ageing of the battery. A control signal is generated on the basis thereof. In one preferred embodiment, said control signal is used to drive a signaling apparatus and thus to present the state of the battery to a user. The present invention can be used, for example, in motor vehicles that are electrically driven.
