First Claim
1. A system for transferring a frequency and modulation pattern of an encoded modulated template transmitter, which functions to actuate a device remote therefrom, to a universal transmitter such that said universal transmitter is thereby programmed to transmit the frequency and modulation pattern of said template transmitter and such that said universal transmitter thereby functions to actuate said remote device, the system comprising:
- said universal transmitter including;
means for transmitting a first signal to a programming unit, means, coupled to said means for transmitting, for tuning a frequency of the first signal to be transmitted, memory means for storing said modulation pattern to be transmitted, means, coupled to said memory means for storing, for modulating the first signal such that said modulation pattern stored in said memory means is transmitted by said universal transmitter when said universal transmitter is actuated, and means, coupled to said means for modulating, for directly actuating transmission of said modulated first signal by said universal transmitter; and
said programing unit separate from said universal transmitter including;
means for receiving a modulated second signal, means, coupled to said means for receiving, for detecting a frequency of the second signal from said template transmitter, means, coupled to said means for detecting, for determining a modulation pattern of the second signal and means, coupled to said means for determining, for transferring the modulation pattern determined by said means for determining to said memory means in said universal transmitter, wherein said tuning means of said universal transmitter, said means for detecting said frequency of said second signal, and said means for determining said modulation pattern function together to match the modulation pattern and frequency of the first and second signals, andwherein said programming unit further including means, coupled to said means for determining, for verifying that said universal transmitter, programmed by said programming unit, transmits said modulation pattern of said template transmitter by analyzing said modulation pattern generated by said programmed universal transmitter.

Abstract
A remote control system having a universal transmitter capable of being programmed to match the frequency and modulation pattern of any pulse modulated remote control transmitter. The system combines the universal transmitter and a separate apparatus for programming the universal transmitter. The programming unit detects the frequency and modulation pattern transmitted by a selected transmitter. The programming unit transfers the detected modulation pattern to the universal transmitter. The universal transmitter is operative to transmit the frequency detected by the programming unit. The universal transmitter thus duplicates the transmission of the selected transmitter. The system, apparatus and methods of this invention are particularly well adapted for application to low cost remote control transmitters permanently installed in vehicles.
