Abstract: A device for protecting a vehicle against use by third parties provides an object detection system which detects the facial area of the driver and compares it, in an image analysis, with stored facial-area image information. For this purpose an image recording camera is positioned in the vehicle so that it automatically takes an image of the facial area when the driver is in position in the driver's seat. When the image recorded by the camera accords with the stored image information, a driving authorization signal is generated which actuates a plurality of vehicle systems to enter a state in which the vehicle can be started.

Abstract: A method and apparatus for transmitting light, wherein a holographic video screen is used as part of an illuminating system. The tendency of such a video screen to backscatter light of certain wavelengths from a predefined direction into a certain solid angle area is utilized to generate holographic images at precisely defined angles. In ambient light, such a video screen need not appear black, or at least dark.

Abstract: A system for monitoring the rear or front space of a motor vehicle being parked is provided. The system is based on a video camera having an image sharpness control, which can follow an object once detected, in terms of its sharpness, with the camera's autofocus over the whole search field, for example, by using fuzzy logic. The device uses this property for an image-processing-supported tracking of the viewing angle of a video camera which is designed to be pivotable and is used for rear-space or front-space monitoring, by which an object limiting the rearward or forward penetration depth of the vehicle can be seen up until contact with the vehicle's bumper. The device eliminates obstacles which previously prevented the use of such video cameras in the rear space monitoring of private cars. A corresponding device can also be provided and used for monitoring the front space of a vehicle.

Abstract: A process for heating the passenger compartment (10) in a motor vehicle, particularly an electric vehicle, having a heating device (12), which is supplied with an air current (40) extracted, via a waste-air duct (11), from the passenger compartment (10). The air current enters into the passenger compartment (10) from the heating device (12) via an intake-duct (13). In order to prevent internal misting of the vehicle's windows, even with a low heating capacity, at least one partial air current (40a), which is branched off from the air current (40) prior to entry into the passenger compartment (10), flows through a sorbent (15) such as zeolite or the like.

One of the heat exchangers, which, together with a circulating pump and a cold store, is incorporated within a circuit of a cold-transporting medium. The circuit is run via the evaporator of a refrigeration unit. The other heat exchanger, together with a circulating pump and a heat store, is incorporated within a circuit of a heat-transporting medium. The circuit is run via the drive system of the electric vehicle for vehicle-cooling purposes.

Abstract: A plate heat exchanger designed as a heat tube in the form of a multi-layer expanded partly laminated body has an integrated, fluidically continuous large-surface channel structure. Formed in the vicinity of the outer edge is a condensate-collecting channel which is fluidically connected unobstructedly to the channel structure. A heating bar or a heating channel is arranged near the edge separately but connected heat-conductively. To prevent condensate from flowing off on one side within the condensate-collecting channel as a result of gravity and/or horizontal acceleration and thereby to ensure the best possible heating effect, the condensate-collecting channel is subdivided into condensate pockets by a plurality of flow obstacles.
