Abstract:
A method and a monitoring unit for monitoring an air pressure in a tire of a motor vehicle register a measured value of the air pressure in the tire. The current and/or future distance of the motor vehicle relative to a service station and/or an operating situation of the motor vehicle associated with a service process is then determined. An alarm signal is only then output if the measured value does not reach a predefinable threshold value and one or both of the conditions applies: the current or future distance of the motor vehicle relative to a service station does not reach a predefinable threshold value, the registered operating situation corresponds to a predefinable operating situation.

Abstract:
The system has a uniform system architecture that is designed for an access authorization request both with and without the use of a transponder. Should a transponder be used, only a corresponding transponder must be fitted in the key that can interact with an immobilizer coil specially provided for this in a receiving unit of the motor vehicle. In this case, the corresponding system requirements have also already been taken into consideration in the system architecture. As a result, the different system requirements for access and right of use systems to a great extent provide flexibility.
Abstract:
The invention relates to a plate-shaped separator for separating fluids from a gas flow, particularly for separating oil mist, wherein the flow hits the separator transversely, wherein the separator comprises a plurality of separating profiles, which are arranged in parallel next to each other transversely to the flow direction of the gas flow and which each form two curved deflection surfaces, which lie opposite each other in a laterally offset manner with the concave side thereof and on which a gas flow to be purified flows along successively, wherein the deflection surfaces enclose an eddy chamber having an inlet gap and an outlet gap between said deflection surfaces and end at the longitudinal edges of the deflection surfaces in a protuberance that projects over the deflection surfaces and extends along the longitudinal edges, wherein in order to further improve the separation of particles from the gas flow to be purified, it is proposed that at least one of the protuberances comprise a first substantially plane outer surface exiting from the deflection surface substantially transversely to the deflection surface and a second substantially plane outer surface connecting thereto at a sharp angle so that the at least one protuberance forms a sharp edge projecting into the gas flow flowing along the deflection surfaces.
Abstract:
In a method for operating an electronic anti-theft system, data communication is effected between the control device and the key further to an access authorization request, whereby the control device unlocks the doors and deactivates an alarm system as a function of the data communication. The data communication for unlocking the doors and the data communication for disarming the alarm system are separate from each other. In this way, the mechanical unlocking of the doors can be initiated immediately after the data communication for unlocking the doors. The corresponding data communication for deactivating the alarm system is effected in parallel with this, whereby extensive cryptological data is exchanged between the control device and the key.

Abstract:
A separator is provided for separating liquids from a gas stream and has a plurality of separating profiles juxtaposed parallel to one another, each profile forming two curved deflection surfaces which lie opposite one another with the concave side laterally offset, wherein the deflection surfaces between them include a swirl chamber having an inlet gap and an outlet gap and terminate at their longitudinal edges in a projection that projects from the deflection surfaces and extends along the longitudinal edges. At least one of the projections has a first, substantially planar outer surface emanating from the deflection surface substantially transversely thereof and a second, substantially planar outer surface adjoining the first outer surface at an acute angle, so that the at least one projection forms a sharp edge that projects into the gas stream flowing along the deflection surfaces.

Abstract:
A low-cost, wide input range, DC-DC voltage-switching converter regulator device for supplying power to various components in an automotive application includes two pairs of serialized switch elements for controlling separate Boost and Buck Modes each through a respective one of said pairs. In particular, the converter regulator device is arranged for under control of a driving voltage below a first threshold voltage outputting a negligible output current, in a Buck-Mode under control of a driving voltage above a second threshold voltage outputting a Buck-Mode flat current level through alternating and mutually opposing conducting states of the first switch elements, and in a Boost-Mode under control of a driving voltage between the first and second thresholds outputting a Boost-Mode flat current level that is substantially lower than the Buck-Mode current level through driving via the inductor a medial tap of serialized second switch elements of which one terminal tap constitutes an output terminal of the converter.
Abstract:
In the device a controllable switch is built into the control device which enables the start authorization and by means of which the supply voltage with which this controllable switch is supplied can be switched off. To check a start authorization a diagnosis can be undertaken which is realized with known resistance elements in the voltage supply line between identification device holder and control device. This allows the voltage drops across the elements to be compared with the corresponding required values. Simple short circuiting of the starter or the ignition is thus no longer possible since this would be detected by the control device as a result of the changes in voltage drop. In addition a fault in the supply voltage or the feed lines can be definitively detected.
