Abstract

The apparatus contains an electronic device and is stuck by suction to a flat surface, such as a vehicle windscreen. The volume subject to suction, lying between the flat surface and the apparatus fixture, is connected to a pressure sensor, and the signal from the pressure sensor is fed to the electronic device.

Description

Die Erfindung betrifft ein an einer überwiegend ebenen Fläche, wie der Windschutzscheibe eines Fahrzeuges, mittels Saugwirkung befestigbares, elektronische Einrichtungen enthaltendes Gerät.The invention relates to a predominantly flat surface, such as the Windshield of a vehicle, attachable by suction, apparatus containing electronic devices.

Ein solches Gerät ist bekannt (Aufsatz: "Zukünftige automatische Gebührenerfassung für den Straßenverkehr" in ntz Bd. 46 (1993) Heft 4, Seiten 258-265). In dem Gerät sind beispielsweise die Fahrzeugdaten, Daten über die zurückgelegten Fahrtstrecken und dergleichen gespeichert, und es enthält elektronische Mittel, um über eine Funkverbindung Daten mit einer Feststation auszutauschen. Derartige Geräte werden auch als elektronische Vignetten bezeichnet. Da die übermittelten Daten dafür benutzt werden, um die zu zahlenden Gebühren zu berechnen, soll es vorkommen, daß Manipulationen in der Weise versucht werden die elektronischen Vignette, das heißt das an der Windschutzscheibe befestigten Gerät, gegen ein anderes Gerät auszutauschen.Such a device is known (essay: "Future automatic Toll registration for road traffic "in ntz vol. 46 (1993) issue 4, Pages 258-265). The vehicle data, for example, are in the device, Data on the distances traveled and the like are stored, and it contains electronic means to transmit data over a radio link to replace a base station. Such devices are also called called electronic vignettes. Because the data transmitted for it should be used to calculate the fees payable manipulations are attempted in such a way that electronic vignette, that is attached to the windshield Device to be exchanged for another device.

Es ist bekannt, das Gerät mittels eines Saugnapfes oder mittels mehrerer Saugnäpfe an der Windschutzscheibe durch Saugwirkung zu befestigen. Anstelle eines oder mehrerer Saugnäpfe kann auch eine elastische Klebebefestigung verwendet werden. In jedem Fall weist die Befestigungseinrichtung an der der Fläche zugewandten Seite, an der das Gerät befestigt ist, zum Beispiel der Windschutzscheibe, einen Raum auf, welcher gegenüber der Umgebung einen Unterdruck aufweist.It is known to use the device by means of a suction cup or by means of several Attach suction cups to the windshield by suction. Instead of one or more suction cups, an elastic one can also be used Adhesive attachment can be used. In any case, the Fastening device on the side facing the surface on which the  Device is attached, for example the windshield, a room on, which has a negative pressure compared to the environment.

Das der Erfindung zugrunde liegende technische Problem besteht darin, das Gerät in der Weise auszugestalten, daß es registriert, wenn es von der Fläche, auf der es befestigt ist, entfernt worden ist und diese Manipulation registriert.The technical problem underlying the invention is to design the device in such a way that it registers when it is from the Surface on which it is attached has been removed and this manipulation registered.

Diese technische Problem ist erfindungsgemäß dadurch gelöst, daß das die Saugwirkung ausübende Volumen zwischen der ebenen Fläche und der Gerätebefestigung mit einem Drucksensor in Verbindung steht, und das Signal des Drucksensors der elektronischen Einrichtung zugeführt ist.This technical problem is solved according to the invention in that the Absorbing volume between the flat surface and the Device attachment is connected to a pressure sensor, and that Signal of the pressure sensor of the electronic device is supplied.

Wenn versucht wird, das Gerät, das heißt die elektronische Vignette durch Krafteinwirkung von der Windschutzscheibe zu entfernen, dann wird zunächst der Druck in dem Volumen erhöht. Wird die Befestigung gelöst, dann bricht die Druckdifferenz zwischen dem Volumen und der Außenatmosphäre zusammen. Die vom Drucksensor gemessenen Drücke bzw. Druckänderungen können in der elektronischen Einrichtung gespeichert und bei Bedarf ausgelesen und zur Erzeugung einer Mißbrauchsanzeige verwendet werden.If you try the device, that is, the electronic vignette through Then remove force from the windshield initially the pressure in the volume increased. If the attachment is released, then the pressure difference between the volume and the Outside atmosphere together. The pressures measured by the pressure sensor or pressure changes can be in the electronic device saved and read out if necessary and to generate a Abuse notice can be used.
