Abstract

A wireless response system includes a base unit and a plurality of handheld response units communicating with the base unit over a wireless communication link. The base unit sends polling commands to the response units over the wireless communication. The response units send the response data to the base unit over the wireless communication link in response to the polling signals. The response data is entered in the respective response units by a user.

Claims

1. A wireless response system, comprising:

a base unit and a plurality of handheld response units communicating with said base unit over a wireless communication link;

said base unit sending polling signals to said response units over said wireless communication link;

said response units sending response data to said base unit over said wireless communication link in response to the polling signals, the response data being entered in the respective response unit by a user;

said handheld response units including microcomputers, each microcomputer including a processor and primary memory accessible by said processor;

said response units including a feature electrical connector that is accessible by said processor; and

a removable feature memory module that is accessible by the respective said processor when said feature memory module is connected with said feature connector.

2. The response system of claim 1 wherein said base unit includes a said microcomputer and a said feature electrical connector.

3. The response system of claim 2 wherein said feature memory module is at least partially programmed by said base unit and used to at least partially control said response units.

4. The response system of claim 1 wherein each of said response units includes a said feature electrical connector and a said removable feature memory module.

5. The response system of claim 4 wherein said base unit includes a said microcomputer and a said feature electrical connector and wherein each said memory module is at least partially programmed when connected with said feature electrical connector of said base unit and used to at least partially control one of said response units.

6. The response system of claim 1 wherein said removable feature memory module comprises a copy protection module to protect program code in said primary memory against operation without said removable feature memory module connected with said feature connector.

7. The response system of claim 1 wherein said removable feature memory module is programmed with preloaded data that is copied by said processor to said primary memory.

8. The response system of claim 7 wherein said preloaded data comprises identification information of a user assigned to one of said response units.

9. The response system of claim 7 wherein said response units include a display and wherein said preloaded data comprises at least one chosen from prompts and icons displayed on said display by said microcomputer.

10. The response system of claim 1 wherein said removable feature memory module is programmed with program code for operating said microcomputer.

11. The response system of claim 1 wherein said removable feature memory module receives data entered by a user with one of said response units.

12. The response system of claim 1 wherein said response units include a housing and at least one removable device that is selectively removable from the housing of the corresponding one of said response units.

13. The response system of claim 12 including a security device for inhibiting removal of said at least one removable device from the housing of the corresponding one of said response units.

14. The response system of claim 13 wherein said at least one removable device comprises a battery.

15. The response system of claim 13 wherein said at least one removable device comprises said feature memory module.

16. The response system of claim 13 wherein said at least one removable device comprises a battery and said feature memory module.

17. The response system of claim 1 wherein said wireless communication link comprises at least one chosen from an RF link and an IR link.

18. A wireless response system, comprising:

a base unit and a plurality of handheld response units communicating with said base unit over a wireless communication link;

said base unit sending polling signals to said response units over said wireless communication link;

said response units sending response data to said base unit over said wireless communication link in response to the polling signals, the response data being entered in the respective response unit by a user;

said response units including at least one removable device, said response unit including a security device for inhibiting removal of said at least one removable device.

19. The response system of claim 18 wherein said response units include a housing and said at least one removable device is selectively removable from the housing of the corresponding one of said response units.

20. The response system of claim 19 wherein said security device inhibits removal of said at least one removable device from the housing of the corresponding one of said response units.

21. The response system of claim 18 wherein said at least one removable device comprises a battery.

22. The response system of claim 18 wherein said at least one removable device comprises said feature memory module that augments a primary memory of one of said response units to which said feature memory module is connected.

23. The response system of claim 22 wherein said at least one removable device comprises a battery and said feature memory device.

24. The response system of claim 18 wherein said wireless communication link comprises at least one chosen from an RF link and an IR link.
