Abstract:
1. An operator for controlling a position of a barrier, comprising: at least one radio frequency transmitter having a predetermined serial number for radio frequency transmitting a radio frequency transmission corresponding to the transmitter, wherein said predetermined serial number remains the same in said radio frequency transmissions; a radio frequency receiver adapted to receive a first radio frequency transmission from a first radio frequency transmitter and adapted to receive a second radio frequency transmission from a second radio frequency transmitter having a second serial number, said radio frequency receiver receiving said serial numbers that remain the same when in an operate mode; a memory comprising a plurality of storage locations; and a controller having a controller controlled serial number location pointer and responsive to the reception by said radio frequency receiver of said first-mentioned radio frequency transmission for storing a first serial number corresponding to said first radio frequency transmitter in one of said plurality of storage locations derived from the controller serial number location pointer, the controller responsive to the reception by said radio frequency receiver of said second radio frequency transmission for storing a second serial number corresponding to said second radio frequency transmitter in another of said plurality of storage locations derived from the controller serial number location pointer, and said controller responsive to said operate mode and the reception of said first-mentioned radio frequency transmission after the storage of said first stored serial number for moving the barrier and said controller responsive to said operate mode and the reception of said second radio frequency transmission after the storage of said second stored serial number for moving baffler, and said controller responsive to a learn mode wherein said radio frequency receiver is adapted to receive new radio frequency transmissions from said radio frequency transmitter which has a new user-changeable serial number changed by the user from said predetermined serial number, said new user-changeable serial number remaining the same when subsequently transmitting said radio frequency transmissions in said operate mode.
