First Claim

1. A method for capturing a subset of output codes from a rolling code sequence device comprising:
- actuating a first function of the device to generate a first output code;
after the actuation of the first function but before actuating any other function, again actuating the first function of the device to generate a second output code;
after the actuation of the first function again, actuating a second function different from the first function of the device to generate a third output code; and
storing into a memory the subset of output codes comprising, in sequential order, the first output code, the second output code, and then the third output code.

Abstract
A subset of codes is efficiently captured from a remote generator and used in a remote access device. The subset of codes contains more codes for common functions than for uncommon functions and enables operation of special functions.

7. A remote transmitter for sending codes to a receiver comprising:
-
a memory storing a subset of output codes, the subset of output codes comprising, in sequential order, a first code, a second code, and then a third code; an input system configured to receive a selected function of among a plurality of functions operable on the receiver; and an antenna configured for sending codes to the receiver; wherein the first code operates a first function of the plurality of functions; wherein the second code operates the first function of the plurality of functions; and wherein the third code operates a second function of the plurality of functions. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A method, performed by a transmitter, of transmitting codes to a receiver, the method comprising:
-
upon receiving an input to operate a specific function of a plurality of functions operable by the receiver, transmit a specific code from a sequential subset of codes configured to operate the specific function; and upon receiving a next input to operate a next function of the plurality of functions and before receiving any other input, transmit the earliest code in the sequential subset of codes after the specific code that operates the next function of the plurality of functions, wherein the receiver is configured to use a rolling code generator to verify codes received from the transmitter; wherein the sequential subset of codes comprises, in sequential order, a first code, a second code, and then a third code; wherein the first code operates a first function of the plurality of functions, wherein the second code operates the first function of the plurality of functions, and wherein the third code operates a second function of the plurality of functions, the second function different from the first function. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method for capturing a subset of output codes for operating a plurality of functions from a rolling code sequence device comprising:
-
generating a sequence of output codes by repeatedly performing sets of sequential function actuations on the rolling code sequence device; and storing into a memory the subset of output codes comprising the sequence of output codes; wherein each set of sequential function actuations comprises; actuating, for a plurality of times, a common function; and actuating, for a number of times that is less than the plurality, an uncommon function; and actuating each function of a plurality of functions at least once. - View Dependent Claims (22)
