Abstract

A Miniature Remote Control System (10) that overcomes the problems encountered by previous remote control devices is disclosed. The present invention uses a remote emitter (12) which integrates a radio transmitter circuit (60) in a small housing (34) that plugs into an existing lighter receptacle (28) in a vehicle (V). When pushed down, the remote emitter (12) transmits a coded serial pulse train (16) to a remote receiver (14) up to 200 feet away. The pulse train (16) has a unique code (20) (one of 19,683) on a 380 MHz carrier frequency. The remote receiver (14) processes the pulse train (16), and extracts the serial transmitter code (20). The transmitter code (20) is then compared to the preset receiver code (22), and, if a match is found, a relay (104) is triggered. When activated, the relay (104) can be used to operate external devices (ED), including garage doors (GD), security gates (SG), burglar alarms (SA), exterior lights (EL) or interior lights (IL).

Dependent claims

A method comprising the steps of:

activating an emitter (12);
said emitter being mounted in a cigarette lighter receptacle (28) mounted in a vehicle (V) having an on-board power source (BAT);
generating a carrier signal (16) when said emitter (12) is activated;
said carrier signal having an embedded predetermined transmission code (20);
and
sensing said carrier signal (16) generated by said emitter (12) using a receiver (14);
said receiver (14) being coupled to an external device (ED) which is activated when said carrier signal having an embedded predetermined transmission code is sensed;
said emitter includes a micro-controller, said micro-controller being programmable using input voltage and ALOHA protocol software;
said emitter also having a voice recognition circuit for providing voice recognition operation;
said emitter including a molded housing;
said emitter including a switch contact ring which is encapsulated and formed integrally in said molded housing;
said emitter further including an antenna;
said antenna being energized when said switch contact ring is engaged;
said adapter being capable of coupling a secondary accessory to said emitter.
