Method and apparatus for a rolling code learning transmitter
First Claim
1. A method for automatically learning a rolling type access code from a learning transmitter by a barrier movement operator, comprising steps of:
- receiving by the barrier movement operator a first rolling type access code from a first transmitter, the first rolling access code having a fixed identification portion recognized by the operator;
beginning a learn mode operation in response to receipt of the first rolling access code by the barrier movement operator;
saving a representation of the first rolling type access code received from the first transmitter in the barrier movement operator;
receiving the first rolling type access code from the first transmitter by the learning transmitter, and storing a representation of the first rolling type access code therein;
receiving, by the operator, a second rolling type access code from the learning transmitter within a predetermined period of time after from receiving the first rolling type access code;
comparing the second rolling type access code with the first rolling type access code saved in the operator;
storing the representation of the second rolling type access code in the operator when the comparing step identifies that a predetermined relationship exists between the first rolling type access code and the second rolling type access code.

Abstract
A barrier movement operator system having a receiver for receiving, learning and responding to transmitted rolling code access codes. The barrier movement operator provides a method and apparatus for learning valid security codes by a security code receiver comprising receiving a first previously learned security code and beginning a learn mode operation in response thereto, within a predetermined period of time, receiving a second security code, having a predetermined relationship to the first security code; and storing a representation of the second security code as a valid security code.

11. A method for automatically learning a new transmitter rolling type access code by a barrier movement operator, comprising steps of:
-
sending a first rolling type access code from a previously known transmitter to the operator; starting an operator auto learn mode by activating the operator in response to the first rolling type access code received by the operator and saving the first rolling type access code in the operator; storing a representation of the first rolling code in a learning transmitter; within a predetermined time limit, receiving by operator, a second rolling type access code derived by the learning transmitter from the stored representation of the first rolling type access code; and saving the second rolling type access code in the operator, when both the second rolling type access code and the first rolling type access code saved in the operator have a correlated fixed identification portion, said fixed identification portion being recognizable by the operator, and the second rolling code is next in sequence to the first rolling code saved in the operator. - View Dependent Claims (12, 13, 14, 15)

16. A barrier movement operator system, comprising:
-
a receiver for receiving, learning and responding to transmitted rolling code type access codes; at least one trained transmitter for operating the system by transmitting a rolling code type access code to the receiver, the rolling code including a fixed identification portion recognized by the system; at least one learning transmitter for learning the rolling code type access code from said trained transmitter in order to operate the system; a controller for evaluating relationship between a learning transmitter rolling type access code and the a trained transmitter rolling type access code; and a timer to run time between last operation of the barrier by the trained transmitter and receipt of transmission from the learning transmitter by the system; and a device for providing a barrier movement in response to access codes received by the receiver. - View Dependent Claims (17, 18, 19, 20)

21. A method for modifying a rolling type operation code for a barrier movement operator, comprising steps of:
-
receiving by the operator a first rolling type operation code from an original learning a transmitter; beginning a learn mode of the operator upon receipt of the first rolling operation code saving the first rolling type operation code in the operator; modifying the first rolling type operation code by a learning transmitter; within a predetermined period of time from the first receiving step, receiving a the modified rolling type operation code from the learning transmitter, the modified rolling operation code having a predetermined relationship with the first rolling operation code; storing the modified rolling type operation code in the operator when received within a predetermined period of time after the beginning of the learn mode; and ending the learn mode the predetermined period of time after the beginning of the learn mode.
