Abstract
1.detailed remote control device, which is of special application to the remote opening of garage doors and which, constituting from two differentiated elements, a transmitting, portable circuit, working in the umf band and a fixed receiver circuit and associated with an electromagnetic device able to command the motor for opening garage doors is essentially characterized in that the emitter circuit comprises an oscillator-modulator stage, low frequency, for a high frequency oscillator stage 1, comprising the oscillating stage low frequency modulator 5 an integrated circuit 6, generator of a square wave, while the high frequency oscillating stage 1 is formed by a transmitter 2 coupled in "hartley" circuit and with a coil 3 made in printed circuit, having been foreseen that the receiver circuit is formed by a high-pass stage 20, followed by a detection stage 22, which is connected at an amplifier passage 26, which is connected to a stabilizing-stabilizing stage 28, stage that attacks an integrated and tunable circuit 30, circuit capable of generating a signal that is directed to an amplifier passage 33 connected to the relay coil 31 or similar switching device. 2.detailed remote control device, according to the previous claim, characterized in that the low frequency oscillator-modulator stage 5 is formed by an integrated circuit 6 generating a square wave of extreme stability with the particularity that the frequency of said square wave is susceptible of variation by means of a potentiometer element. 3.detailed remote control device, according to claim 1, characterized in that the high pass stage 20 is formed by a transistor mounted on a common base, with the particularity that the selective and tunable integrated circuit 30 is tuned in accordance with the working frequency of the transistor. Emitter circuit and is activated by presence of signal in the detection stage 22. 4.detailed remote control device, according to claim 1, characterized in that the different operating codes of the emitting circuit and of the receiver circuit are made by combining the high frequency signals generated in stage 1 with the low frequency signals generated in the stage 5. 5.detailed remote control device, according to previous claims, characterized in that both the emitting circuit and the receiver circuit have two operating channels. 6.detailed remote control device.
