Electronic anti-theft device

The subject of the invention is an electronic theft detection device, which are suitable for influencing the supply of any consumer device that functions electrically, electromechanically, electropneumatically, or in a similar manner.

Win anti-theft devices for motor vehicles in view of the increasing and already very large number of vehicle thefts Meaning.

The commercially available anti-theft devices however, do not provide adequate safeguards as they are easily identifiable and bypassable.

This fact is essentially due to the fact that the anti-theft devices currently on the market are available, just a mechanical break in a particular electrical, electromechanical or electro-pneumatic circuit.

Hence the restoration is the same circle a sufficiently experienced person without any particular difficulty.

The invention is based on the object of the aforementioned functional disadvantages by using a

909843/0677

electronic anti-theft device.

This anti-theft device should namely directly on the primary supply circuit of the electrical current act in the sense that the supply itself is subordinate to the occurrence of certain conditions is.

The stated object is achieved according to the invention solved electronic anti-theft device having a device by means of which the formulation or the combination of numbers and / or letters and / or conventional characters via a push button or key control is possible.

The phrase buttons for the various alphanumeric or conventional signals can in particular, it must also be scattered, that is to say not combined on a single support element.

The signals mentioned are also fed to an appropriately programmed memory which, after processing the signals themselves and comparison with the stored signals, consent impulses are generated.

These approval impulses can be of an electrical nature or of electromagnetic, radio-transmitted waves including visible light and infrared rays or also consist of ultrasound.

909843/0677

It is also particularly advantageous to mix the aforementioned Control and approval signals through application of mixing and demixing devices.

The device thus formed acts on the supply of one or more circles and ensures that the Supply itself only takes place with consent.

The same device can be connected to electrical, electromechanical and electropneumatic elements and devices including motors, doors, car doors, Bonnets and luggage compartments, which are provided with suitable servo systems, are attached.

The invention is explained in more detail below with reference to the exemplary embodiment shown in the drawing explained. Show it:

FIG. 1 shows a block diagram of an exemplary embodiment of an anti-theft device according to the invention and

in Figure 2 an embodiment of the control keyboard the combination device according to the invention is shown.

Thereafter belongs to the electronic according to the invention Anti-theft device a combination device 1, which is preferably provided with an operating keyboard 2 with numeric or alphabetic or alphanumeric

909843/0677

is provided with meric characters or with conceptual characters, this keyboard 2 in particular having two keys 3 and 4 for closing and opening the control circuit.

The pulses generated by this combination device are fed to an appropriately programmed memory 5, with which a consent device 6 interacts, which depends on the data supplied from the memory the approval of the supply of the general consumers 8 or 9 by the direct current or alternating current generator 7 gives or not granted.

The approval signals can in particular both from electrical impulses as well as from ultrasound or electromagnetic waves or light rays (infrared rays) exist.

Claims (2)

Expectations : 1.! Electronic anti-theft device, g e - denotes a device (2) by means of which the formulation or the combination of numbers and / or conventional characters via a push button or key control with also not combined Push buttons or buttons, these push buttons (3, 4) or buttons being able to generate signals to control, which are fed to a correspondingly programmed memory (5), which after processing of the signals themselves and comparison with the stored signals or electrical consent impulses electromagnetic waves including visible light and infrared rays or by ultrasound generated consent pulses, these control and consent signals by mixed and Separation devices can be mixed with each other and the device thus obtained on the supply of a or more circles (8,9) acts in such a way that the supply itself only takes place with consent, and where the same device at the same time to both the electrical, electromechanical and electropneumatic Members and devices including engines, doors, car doors, hoods and luggage compartments, which are provided with suitable servo controls, can be attached. 2. Electronic anti-theft device according to claim 1, characterized by a combination device (1) those with a keypad with numeric or alphabetic or alphanumeric · "· 2 - 909843/0677
ORIGINAL INSPECTED Characters or with conceptual characters, where the keyboard keys for closing and opening the control circuit having. Electronic anti-theft device according to claim 1 and 2, characterized in that, ' that the pulses generated by the mentioned combination device (1) are stored in a programmed memory (5) are supplied, with which a consent device (6) interacts, which depends on the memory (5) self-received data the supply of certain consumers (8,9) on the part of a direct current or various current generators (7) are permitted or not. Electronic anti-theft device according to a of claims 1 to 3, characterized in that the consent signals from electrical Pulses, ultrasound, electromagnetic waves, or light rays (infrared rays). 909843/0677
