Method and apparatus for a rolling code learning transmitter
First Claim
1. A trainable security code transmitter configured to operate with a security code receiver, the trainable security code transmitter comprising:
- means for receiving at the trainable security code transmitter from a pre-configured security code transmitter a security code transmission comprising, at least in part, a fixed identification portion and a rolling code portion;
means for determining a valid subsequent transmission from the trainable security code transmitter to the security code receiver based at least in part upon the rolling code portion and the fixed identification portion, the valid subsequent transmission providing an indication to the security code receiver identifying the valid subsequent transmission as coming from an unlearned transmitter instead of a known security code transmitter and causing a movable barrier operator associated with the security code receiver to automatically enter a learn mode;
means for transmitting to the security code receiver the valid subsequent transmission from the trainable security code transmitter.

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.

6. An apparatus comprising:
-
a trainable security code transmitter configured to operate with a security code receiver, the trainable security code transmitter comprising a button configured to receive user actuation; the trainable security code transmitter configured to; within a time of user actuation of the button, receive from an already trained security code transmitter a security code transmission comprising, at least in part, a fixed identification portion and a rolling code portion; determine a valid subsequent transmission based at least in part upon the rolling code portion and the fixed identification portion; and transmit to the security code receiver the valid subsequent transmission, the valid subsequent transmission providing an indication to the security code receiver identifying the valid subsequent transmission as coming from an unlearned transmitter instead of a known security code transmitter and causing a movable barrier operator associated with the security code receiver to automatically enter a learn mode. - View Dependent Claims (7, 8, 10)
