Abstract

A modifiable transmitter is used with an operator to control a position of a barrier. The operator includes a controller for comparing radio frequency transmissions received with stored serial numbers so that the controller can move the barrier when a radio frequency transmission matches any one of the stored serial numbers. The transmitter includes a housing that carries an encoder. A function button is carried by the housing, wherein actuation of the button generates in a first non-standard way a new serial number that can be learned by the controller to allow the modifiable transmitter to move the barrier by emitting the radio frequency transmission. A second non-standard way, which can only be implemented after use of the first non-standard way, may also be used to generate a new serial number. A restricted access button may also be activated to generate a new serial number.

Claims

1. A system for controlling a position of a barrier comprising:

at least one radio frequency transmitter having a user-changeable serial number associated with each radio frequency transmission corresponding to each transmitter, said transmitter configured for remote use with the system; and

an operator comprising;

a radio frequency receiver adapted to receive a first radio frequency transmission from a first radio frequency transmitter, and adapted to receive a second radio frequency transmission from a second radio frequency transmitter having a second user-changeable serial number,

wherein each said radio-frequency transmitter provides a function button that when actuated in a first way performs a predetermined function and when actuated a second way changes said user-changeable serial number, each said radio-frequency transmitter including an encoder which is initially programmed with a manufacturer'"'"'s key and a current serial number, and

wherein a first actuation of said function button in said second way for a first predetermined period of time causes said encoder to encrypt said current serial number with said manufacturer'"'"'s key to generate said new serial number, and wherein subsequent actuations of said function button in said second way requires a predetermined sequence of function button actuations to encrypt said current serial number with said manufacturer'"'"'s key to generate said new serial number;

a memory comprising a plurality of storage locations; and

a controller connected to said radio frequency receiver, said controller comparing any radio frequency transmissions received from said at least one transmitter with learned serial numbers stored in said plurality of storage locations, wherein said controller enables movement of the barrier when any one of said radio frequency transmissions matches any one of said learned serial numbers stored in said plurality of storage locations.

2. The operator according to claim 1, wherein said encoder encrypts said new serial number with said manufacturer'"'"'s key to generate a new encryption key.

3. The operator according to claim 1, wherein said controller is placed in a learn mode prior to storing said user-changeable serial number.

4. The operator according to claim 1, wherein said predetermined sequence comprises:

actuating said function button for a second predetermined period of time, releasing said function button for a third predetermined period of time, and actuating said function button for a fourth predetermined period of time.

5. The operator according to claim 4, wherein said second and fourth predetermined periods of time are longer than said first predetermined period of time.

6. The operator according to claim 5, wherein said second predetermined period of time is longer than said fourth predetermined period of time.

7. The operator according to claim 5, wherein said fourth predetermined period of time is longer than said second predetermined period of time.

8. A modifiable transmitter used with an operator capable of controlling a position of a barrier, wherein the operator includes a controller for comparing received radio frequency transmissions with stored serial numbers so that the controller enables movement of the barrier when a radio frequency transmission matches any one of the stored serial numbers, the transmitter comprising:

a housing;

an encoder carried by said housing; and

a function button carried by said housing wherein actuation of said function button in a first normal way causes said transmitter to generate the radio frequency transmission, and

wherein actuation of said function button in a non-typical way in a first sequence causes said encoder to generate a new serial number that can be learned by the controller to allow the modifiable transmitter to move the barrier when emitting the radio frequency transmission, and

wherein all subsequent actuations of said function button in said non-typical way are in a second sequence that is different than said first sequence in order to cause said encoder to generate another new serial number.

9. The modifiable transmitter according to claim 8, wherein said encoder is initially programmed with a manufacturer'"'"'s key and a current serial number, wherein said current serial number is encrypted with a manufacturer'"'"'s key upon actuation of said function button to generate said new serial number, and wherein said encoder encrypts said new serial number with said manufacturer'"'"'s key to generate a new encryption key.

10. The modifiable transmitter according to claim 9, wherein said new serial number is generated prior to teaching any serial number to the operator.

11. The modifiable transmitter according to claim 9, wherein said first sequence comprises pressing said function button for a first predetermined period of time and said second sequence comprises pressing said function button for a second predetermined period of time, releasing said function button for a third predetermined period of time, and pressing said function button for a fourth predetermined period of time.

12. The modifiable transmitter according to claim 11, wherein said second and fourth predetermined periods of time are each longer than said first predetermined period of time.

13. The modifiable transmitter according to claim 12, wherein said second predetermined period of time is longer than the said fourth predetermined period of time.

14. The modifiable transmitter according to claim 12, wherein said fourth predetermined period of time is longer than said second predetermined period of time.

15. A method for generating and learning a new transmitter serial number for use with an operator capable of moving a barrier, comprising:

providing in the operator a controller with a receiver capable of receiving radio frequency transmissions;

providing a memory device connected to said controller, said memory device capable of having serial number based codes stored therein;

providing a transmitter housing which carries therein at least an encoder capable of emitting radio frequency transmissions, and at least one function button for actuating said encoder, wherein said encoder is initially programmed with a predetermined serial number; and

generating a new serial number that can be transmitted by said encoder upon actuation of said at least one function button prior to learning said transmitter to the operator.

16. The method according to claim 15, wherein said generating step comprises;

depressing and holding said at least one function button for a first predetermined period of time.

17. The method according to claim 16, wherein said generating step further comprises;

releasing said at least one function button after said first predetermined period of time has expired to generate said new serial number, wherein said serial number can only be generated in this manner once.

18. The method according to claim 17, wherein all subsequent said generating steps further comprise:

depressing and holding said at least one function button for a second predetermined period of time, wherein said at least one function button must be depressed within a third predetermined period of time from when said at least one function button was released; and

aborting generation of said new serial number if said at least one function button is not released after said first predetermined time period has expired.

19. The method according to claim 18, wherein said subsequent generating step further comprises:

releasing said at least one function button after expiration of said second period of time; and

aborting generation of said new serial number if said at least one function button is released prior to expiration of said second period of time.
