"Electronic, acoustic indicator"

The present invention relates to a Electronic, acoustic indicator, which is used to control both the direction indicator light and the low beam as well as for the control of the water circulation, oil, fuel level, release of the handbrake, speed limits and the like, can be used for vehicles of all types.

There are known devices, in particular for directional light indicators and for low beam, the ■ are located on the dashboard of the vehicles, but are not reliable in terms of effectiveness and offer even less in terms of speed, so that often when a signal is not switched off as a result caused by forgetfulness etc. accidents, including fatal consequences.

The purpose of the present invention is to avoid the difficulties mentioned; and it has as an object an electronic audible indicator that has been found to be of great use, and that on the The principle of the multivibrator is based on a flip-flop circuit, which is attached to the dashboard of the vehicle and switched on on the existing electrical circuit, the operating speed or acoustically Effectiveness of the device under control by means of a suspend signal or not, as often the circuit of this device comes into operation signals.

The attached drawing represents the scheme of the switched-on electronic circuit, as not

limiting example, on the electrical intermittent Directional circuit as well as those dipped headlights of a vehicle.

Two transistors 1, 1 'of the PNP and KPN type, a resistor, are switched on in the electrical circuit 2 of 33o ohms, a capacitor 3 of 47oo pF, a potentiometer 4 of 3 ohms, a speaker 5, a Electrolytic capacitor 6 of 5o microfarads connected to the positive pole of the directional switching circuit another electrolytic capacitor 7 is connected of 5o microfarads connected to the positive pole of the low beam circuit during the Conductor 8 connected to the negative pole of the battery is. .

The advantages are as follows:

a) Immediate display by means of acoustic recurring Signals when the directional circuit comes into action;

b) Immediate indication of the defectiveness of any directional light, since the indicator has no sound lets sound;

c) Information about the functioning of the dipped lights by means of a continuous acoustic Signals;

d) Continuous warning for the driver;

e) insignificant electrical power consumption, since the charges of electrostatic energy are used;

f) operational safety.

With reference to the other applications mentioned above, the indicator according to FIG Invention can be used advantageously for one or more electrical auxiliary circuits, which among themselves have similar characteristics, by means of connections or electrical contacts, e.g. in the electrical circuits made of warning lights, or others that are also not very effective on cognition visual recording by the driver of the vehicle.

With a simple application and faster and safer signaling, you have the option of using the acoustic Controls on all the visual controls of the

009837/1565

to extend different control lamp circuits, with immediate recording of the irregularity by means of an acoustic signal without the driver's attention when steering the vehicle distract.

Of course, the construction details can include the arrangement of the various elements and the scheme of the electronic The circuit vary within wide limits to accommodate the various practical applications without leaving the scope of the invention. ■
