Method and apparatus for displaying blocked transmitter information

1. A method for use with a control device, which control device is operably coupleable to a movable barrier operator and receives movable barrier operator instructions from a plurality of transmitters, each of which transmitters is identifiable by a unique identifier, the method comprising:

providing a memory containing a plurality of the unique identifiers, wherein at least some of the unique identifiers can also have stored in correspondence therewith a blocking indicator to indicate that the unique identifier associated with the blocking indicator is not authorized to control at least one aspect of the movable barrier operator;

upon detecting assertion of a first user interface input that comprises a command to display blocked unique identifiers, displaying at least a first memory location address as corresponds to a unique identifier as is then stored in the memory in association with one of the blocking indicators.

2. The method of claim 1 and further comprising, upon detecting assertion of a second user interface input that comprises a command to display additional blocked unique identifiers, displaying at least an additional memory location address as corresponds to a unique identifier as is then stored in the memory in association with one of the blocking indicators.

3. The method of claim 2 wherein, when there is no additional blocked unique identifier to display, displaying at least one earlier displayed memory location address as corresponds to a unique identifier as is then stored in the memory in association with one of the blocking indicators.

4. The method of claim 1 wherein detecting assertion of the first user interface input comprises detecting tactile assertion of the first user interface.

5. The method of claim 4 wherein detecting tactile assertion of the first user interface includes detecting tactile assertion of a keypad.

6. The method of claim 4 and further comprising providing a keypad that includes an “*” key and wherein detecting tactile assertion of the first user interface includes detecting tactile assertion of the “*” key.

7. The method of claim 6 wherein detecting tactile assertion of the first user interface includes detecting tactile assertion of at least one additional key following assertion of the “*” key.

8. The method of claim 7 wherein detecting tactile assertion of at least one additional key includes detecting tactile assertion of the “5” key.

9. The method of claim 7 and wherein detecting assertion of a second user interface input includes detecting tactile assertion of only the at least one additional key.

10. A device for use with a movable barrier operator comprising:

memory means for storing identifying information as corresponds to a plurality of remote control transmitters and blocking information in association with any identifying information that corresponds to specific remote control transmitters that are not fully authorized with respect to the movable barrier operator;

display means for displaying at least memory location addresses;

user interface means for causing memory location addresses that correspond to identifying information for blocked remote control transmitters to be displayed in response to a command that blocked transmitters be displayed.

11. The device of claim 10 wherein the user interface means displays only one memory location address at a time.

12. The device of claim 11 wherein the user interface means further causes the display to iterate a serial presentation of memory location addresses for blocked remote control transmitters.

13. The device of claim 11 wherein the user interface means further causes the display to present a previously presented memory location address for a blocked remote control transmitter when memory location addresses for all presently blocked remote control transmitters have already been displayed.

14. The device of claim 13 wherein the user interface means comprises a keypad.

15. A method for use with a control device that receives instructions from a plurality of transmitters, each of which transmitters is identifiable by a unique identifier, the method comprising:

providing a memory containing a plurality of the unique identifiers, wherein at least some of the unique identifiers can also have stored in correspondence therewith a blocking indicator to indicate that the unique identifier associated with the blocking indicator is not authorized to provide at least one instruction;

upon detecting assertion of a first user interface input that comprises a command to display blocked unique identifiers, displaying at least a first memory location address as corresponds to a unique identifier as is then stored in the memory in association with one of the blocking indicators.
