Abstract

A method for pairing an identification (ID) transmitter and a base of an authentication device includes a programmer initializing the base by transferring an assigned base identification and a code to the base via a first link. The first link differs from a control link used by the ID transmitter to communicate a code to the base. The base then initializes the ID transmitter by transferring to the ID transmitter via a second link an assigned ID transmitter identification which corresponds to the base identification of the ID transmitter and the code. The second link differs from the other links. The ID transmitter is initialized in order to receive authentication from the base to cause the base to trigger an object assigned to the base when the ID transmitter has an ID transmitter identification corresponding to the base identification and communicates the code to the base via the control link.

Claims

1. A method for pairing mobile identification transmitters (ID transmitters) and base stations of an authentication device, the method comprising:

a mobile programming unit initializing at least one base station by communicating with the at least one base station via a first programming data transmission link, wherein the first programming data transmission link differs from a control data transmission link used by ID transmitters to communicate a crypt code to the at least one base station in order to have the at least one base station grant authentication to the ID transmitters;

wherein the programming unit initializes the at least one base station by assigning an individual base station identification to each of the at least one base station, and then transferring the assigned individual base station identification and a crypt code to the at least one base station via the first programming data transmission link;

the at least one base station initializing at least one ID transmitter by communicating with the at least one ID transmitter via a second programming data transmission link, wherein the second programming data transmission link differs from the first programming data transmission link and the control data transmission link, the at least one ID transmitter being initialized in order to receive authentication from the at least base station to cause the at least one base station to trigger an object assigned to the at least one base station when the at least one ID transmitter has an individual ID transmitter identification corresponding to the base station identification of the at least one base station and communicates the crypt code to the at least one base station via the control data transmission link; and

wherein the at least one base station initializes the at least one ID transmitter by assigning an individual ID transmitter identification corresponding to the at least one base station identification to the at least one ID transmitter, and then transferring the assigned individual ID transmitter identification and the crypt code to the at least one ID transmitter via the second programming data transmission link.

2. The method of claim 1 further comprising:

the at least one ID transmitter transmitting feedback to the at least one base station via the control data transmission link if the assigned individual ID transmitter identification and the crypt code has been received and stored by the at least one ID transmitter; and

after the at least one base station receives the feedback, the at least one base station blocks reassignment of the assigned individual ID transmitter identification to other ID transmitters.

3. The method of claim 2 further comprising:

the at least one base station transmitting feedback to the programming unit if the assigned individual base station identification and the crypt code has been received and stored by the at least one base station; and

after the programming unit receives the feedback, the programming unit blocks reassignment of the assigned individual base station identification to other base stations.

4. The method of claim 3 wherein:

the feedback to the programming unit contains information about the individual ID transmitter identification assigned by the base station.

5. The method of claim 1 further comprising:

using a base station counter to count the base station identifications assigned by the programming unit to the at least one base station; and

using an ID transmitter counter to count the ID transmitter identifications assigned by the at least one base station to the at least one ID transmitter.

6. The method of claim 5 further comprising:

the programming unit recording a base station counter value and an ID transmitter counter value; and

the programming unit transferring the next unassigned ID transmitter identification to the at least one base station during initialization of the at least one base station by the programming unit.

7. The method of claim 1 wherein:

the programming unit assigning an object identification to the object, wherein the programming unit transfers the object identification to the at least one base station via the first programming data transmission link during initialization of the at least one base station by the programming unit.

8. The method of claim 1 wherein:

the control data transmission link is a radio frequency (RF) link.

9. The method of claim 1 wherein:

the first programming data transmission link is an audio frequency link.

10. The method of claim 1 wherein:

the second programming data transmission link is an audio frequency link.

11. An authentication device comprising:

at least one mobile identification transmitters (ID transmitter);

at least one base station assigned to an object, wherein each base station and each ID transmitter has a communication device to perform communication with one another; and

a transponder programming unit having a readable memory containing a crypt code and memory locations to store base station identifications and ID transmitter identifications, wherein the transponder programming unit and the base station each have a communication device to perform communication with one another;

wherein each base station has a readable memory to store a crypt code communicated to the base station by the transponder programming unit, the readable memory of each base station has memory locations to store a base station identification assigned and communicated to the base station by the transponder programming unit and to store ID transmitter identifications communicated to the base station by the transponder programming unit;

wherein each ID transmitter has a readable memory to store the crypt code assigned and communicated to the ID transmitter by a base station, the readable memory of each ID transmitter has memory locations to store an ID transmitter identification assigned and communicated to the ID transmitter by the base station, wherein the ID transmitter identification and communicated to the ID transmitter by the base station corresponds to the base station identification of the base station.

12. A method for pairing a mobile identification transmitter (ID transmitter) and a base station of an authentication device, the method comprising:

a mobile programming unit initializing the base station by communicating with the base station via a first programming data transmission link, wherein the first programming data transmission link differs from a control data transmission link used by the ID transmitter to communicate a crypt code to the base station in order to have the base station grant authentication to the ID transmitter;
