Tilman Herickell Auto-Marder-STOP Sheet 1

Description

Martens are increasingly posing a threat to the safety of road users when they damage vital vehicle components (e.g. brake lines) by biting into them. It is a well-known fact that these ^animals - like dogs and cats - can perceive sounds up to the high ultrasonic range, and the attempt to deter the animals using a constant ultrasonic field is therefore obvious and well-known. The deterrent device being applied for is intended to improve on conventional measures in that it does not allow the animals to become accustomed to it, and in addition, the type of sound generated, which is inaudible to humans, achieves an optimum volume - and thus deterrence - while at the same time taking into account the lowest possible power consumption, which makes it practically maintenance-free. .The ability to test the function of the device acoustically at any time (for which a corresponding control element is provided) and to visually demonstrate the function of the device, which is inaudible to humans, is a sales booster, as it also has a directly visible benefit. This is a decisive advantage over devices currently on the market, which do not allow you to see whether they are still functional after a certain time and can continue to provide defensive security. The sensible combination as a simultaneous battery detector increases the practical usability of the device, which car owners will welcome. In addition, the possibility of combining the sounder as a signaling device for a car alarm system (against two-legged "car martens") resulting from the described concept is a factor that increases the utility and advertising value of the device. The constructive solution of the design of the device in conjunction with the achievement of &egr;&igr;.. _&bgr; &iacgr; The simplest possible installation in the vehicle should also be emphasized here, as this also results in the advantages mentioned in detail.- »through

Functional description, block diagram, Fig.2

The device is powered by the vehicle's on-board voltage, via the metal housing through a conductive mounting plate from the car body (left) for the negative pole and via a simple insulated cable (9), fused (33) _; for the positive pole. The on-board voltage is reduced and stabilized by means of a voltage stabilization circuit (27). A voltage monitoring circuit (29) is located directly on the on-board voltage supply (9). If the on-board voltage falls below the setpoint, this activates a hazard warning generator (30). This always causes the display element (7) to flash via an OR gate (19) and the display driver (20). When the supply line is connected to (9), a directional pulse for the alarm time generator (21) is generated by building up the stabilized voltage according to (27) in a pulse circuit (28); as a result, the sounder (2) remains in the idle state at this moment. The gate circuit generator (14) determines the pause/signal ratio of the sound output in the ultrasonic range; it periodically starts the ultrasonic frequency generator (13), which in turn is determined by the wobble generator (12) in terms of frequency height and range. By controlling the gate circuit (17), the generated sound signal is sent via a push-pull output stage (18) to the sound generator (2) and its second connection (11). A power-saving circuit (31) causes the output stage (18) to be switched off completely to minimize power consumption during the sound pauses. The sound pauses can alternatively be filled by pulses from an intermediate clock generator (15), which reach the output stage (18) and the sound generator (2) via the OR gate (16) and the gate (17). As soon as the gate (17) releases a signal to the output stage (18), the display driver (20) and thus the display element (7) is activated. During this phase, the display element (7) flashes in time with the wobble generator (12), which reaches the display driver (20) via the AND gate (32) and the OR gate (19). This provides an optical check of the operational readiness. The acoustic check, as well as the generation

of the alarm signal, via a control signal that is sent either from the control button (5) or from the alarm time generator (21) via the OR gate (24) to the circuit for changing the frequency range and range (2fi). This immediately starts the signal from both generators (12^13) and opens the gate (17), this time independently of the timing of the gate clock generator (14); the signal appears immediately at the output of the sound transmitter (2) The alarm time generator (21) can be triggered by an internally installed motion sensor (23) as well as by an alarm signal from an external alarm sensor coming via the single line (22); the triggering reacts to switching edges and can therefore be connected universally. In combination with the alarm time from (21), the button (5) has a dual function, as in addition to the above function, it cancels the alarm time signal from (21) via the OR gate (25). -
