Method and apparatus for a rolling code learning transmitter
First Claim
1. A method of learning valid security codes by a security code receiver, comprising steps of:
- receiving a first security code;
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.

Abstract
A barrier movement operator system having 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; 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 the relationship between the learning transmitter rolling type access code and the trained transmitter rolling type access code; and a device for providing a barrier movement in response to access codes received by the receiver.
The barrier movement operator provides a method of learning valid security codes by a security code receiver comprising the steps of receiving a first security code, then 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.

2. A method for automatically learning a rolling type access code from a learning transmitter by a barrier movement operator, comprising steps of:
-
receiving a first rolling type access code from a first transmitter, the code having a fixed identification portion recognized by the operator;
saving a representation of the first rolling type access code received from the first transmitter in the 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;
receiving, by the operator, a second rolling type access code from the learning transmitter within a predetermined period of time 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. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A method for automatically learning anew 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 (13, 14, 15, 16)

17. 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 a trained transmitter rolling type access code; and
a device for providing a barrier movement in response to access codes received by the receiver. - View Dependent Claims (18, 19, 20, 21, 22)

23. 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 transmitter;
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 modified rolling type operation code from the learning transmitter, the modified code having a predetermined relationship with the first code;
storing the modified rolling type operation code in the operator.
