摘要:
A protective system for an electrical network includes input and output units (E/A-1, . . . , E/A-7) and a data processing unit. The input and output units detect and digitize incoming analog signals present at outlets (1, . . . , 7) of an electric-operating means which needs to be protected, for instance a bus bar. The digitized measurement signals are hierarchically connected/coupled to the data processing unit, in accordance with predetermined protective criteria. Thus, error signals which are generated in response to the detection of system failures are supplied via the input and output units (E/A-1, . . . E/A-7), and these error signals act upon switching stations provided at the outlets (1, . . . , 7). With each of the outlets, for instance outlet 3, there are associated two input and output units, for instance units E/A-1, and E/A-3, which units operate independently of one another. The data processing unit is in the form of a data-transfer and processing network and includes computers (T.sub.1, . . . , T.sub.6) which act through a plurality of network nodes. The protective device of the invention is characterized by having a high level of redundant circuitry and is modularly constructed to obtain system expandability and flexibility.

The invention relates to an optical anti-dazzle device, more particularly for motor vehicles, with a light receiving component (2) and a light source (3), the light emission of which can be controlled in dependence on the light emission of a source of dazzle. In order to achieve such a relatively large, mainly homogeneously shining surface in such a anti-dazzle device in spite of its compact, flat dimensions, according to the invention the light source (3) is assigned a flat light guide (5) with at least one narrow edge surface (6) and at least one flat light emission surface (10), wherein the light from the light source (3) can be launched via the narrow edge surface (6), and the area of the light emission surface (10) is a multiple of the area of the narrow edge surface used for launching light. Another form of embodiment of the anti-dazzle device according to the invention consists in the light source being formed by a luminous film, which can be activated by an electronic device in such a way that the luminous film forms an essentially homogeneously shining surface. A further embodiment of the anti-dazzle device according to the invention consists in the light source comprising organic light-emitting diodes which are arranged on at least one glass carrier or at least one flexible, transparent carrier made of plastic.

The valve closure layer (6) comprises at least one, preferably a plurality of, gas throughflow opening(s) (4) surrounding the gas outflow opening (1) in an annular manner and offset relative to the gas outflow opening (1) without overlap, and said valve closure layer overlaps the gas outflow opening (1) without an opening. A greater airbag internal pressure presses the valve closure layer (6) more firmly against the external layer (2) and thus reduces the gas outflow through the gas outflow opening (1). Such an airbag cover element may be configured as an integral part of the airbag cover or as a separate functional part to be attached over an airbag cover opening (on the inside or outside of the airbag).
摘要:
A device is described for determining the driving capability of a driver in a vehicle which has an illumination device (1) for illuminating at least one of the driver's eyes, a picture taking device (2) for taking pictures of the illuminated eye, an evaluation device (3) which serves to evaluate the pictures taken by the picture taking device, and a data storage (4). The device is essentially characterised in that the illumination device (1) illuminates with flash type light or intermittently at least one of the driver's eyes, the evaluation device (3) comparing measured values taken for the driver's pupil reaction by means of the picture taking device (2) with at least one normal value for a pupil reaction stored in the data storage (4), and when the normal value is not reached by the measured values for the pupil reaction, having an effect upon a control device (5) such that the vehicle is prevented from starting up or a vehicle in operational state is prevented from being driven on after it has stopped.
