Abstract: A method of keyless locking of a motor vehicle is described. A transponder exchanges a code with a transceiver. A control unit compares this code with the expected code and, if a match is found, activates a closing system of the vehicle in the sense of locking it. This control unit activates at least one display means. A locking command is generated on actuation of at least one operating element. In a first step, a search signal is delivered by the transceiver when the operating element is actuated in order to determine the position of the transponder on the basis of the response signal sent back by the transponder. In a second step, the display means is activated when the transponder is in the interior of the vehicle and/or on the side of the vehicle opposite the actuated operating element. In a third step, the closing system is activated in the sense of locking it if the operating element has been actuated again.

Abstract: A device according to the present invention is proposed for the keyless operation of a motor vehicle (8), having a transponder (14) that sends a code to at least one transceiver (12). A control unit (10) compares the code to an expected code, and upon agreement, enables at least one component (16, 18) necessary for the operation of the motor vehicle (8), and deactivates it in the shutdown state of the motor vehicle (8). A timer (T2, T3) is provided, whose output value is compared to a specifiable time duration (t2, t3), the at least one component (16, 18) necessary for the operation of the motor vehicle (8) being deactivated when the output value of the timer (T2, T3) exceeds the specifiable time duration (t2, t3).

Abstract: The invention relates to a method of setting a position of an object of measurement in layer thickness measurement by X-ray fluorescence in which a beam of an optical recording device is projected into the beam of the X-radiation and in which the surface of the object of measurement is recorded and output as an image comprising a number of image points, with the distance between the surface and the collimator being changed by an absolute amount of a path of movement, with changes in brightness of the image points being recorded in at least one measuring plane during the at least one change of the distance between the surface and the collimator, with the maximum of the difference in brightness of the image points of an image being ascertained after the at least one change of the absolute amount of the distance, and with the distance between the collimator and the object of measurement being set to the position of the ascertained maximum of the difference in brightness.

Abstract: The invention relates to a method for measuring the thicknesses of thin layers by X-ray fluorescence, in which a specimen having the layer to be studied is positioned in view and subsequently X-radiation is directed onto the layer to be studied and emitted fluorescent radiation is detected by means of a radiation detector and the layer thickness is determined, in which on positioning the specimen there is a focussing by adjusting a focussing element along its optical axis and the position of the focussing element is determined with the layer in focus. An apparatus for layer thickness measurement with X-ray fluorescence according to the invention having a X-ray tube, a detector and an observing device with a focussing element provides for the latter to be movably mounted along its optical axis and provided with a position measuring device.

Abstract: An improved method for exchange of data in data processing installations, especially Controller Areas Networks (CAN), permits acknowledged and segmented transmission of data strings, of arbitrarily long length, between at least two stations in the network or other data processing installation. The method includes the transmission of the messages associated with the data by means of frames; the frames contain a header field and a data field. In the event of contention between multiple stations of the data processing installation for access to the bus connection, which frame has priority is determined by evaluating the respective header fields. In the data field of the frame, there is a control information field (58, 95) containing a message code which serves to identify the message type. The message codes distinguish among activation messages (AR, AC), data messages (DT), and acknowledgement (AK) messages. This permits transmission of data strings, of limited length, with acknowledgement.
