Abstract

In a system for managing information from electronic pens, each electronic pen includes a memory which is designed to store controlling software and a set of templates. Each template associates pen positions with functionality implemented by the controlling software. In a method and arrangement of controlling operation of electronic pens, a separate set of template versions are generated for each of a plurality of different versions of the controlling software. A pen, which stores a given version of the controlling software, is provided with a corresponding set, in which all template versions suitably indicates functionality which is fully implemented by the given version of the software.

Claims

1. A method in a computer system communicating with an electronic pen, comprising:

deriving from the pen a version identifier indicative of a set of processing rules stored by the pen;

providing said logic version to the pen.

2. The method of claim 1, wherein every rule identifier in said logic version is indicative of a processing rule in said set of processing rules.

3. The method of claim 1, further comprising:

deriving an upgrade reference from a database associated with the computer system, wherein at least said step of providing said logic version is conditioned by detection of a given characteristic of said upgrade reference.

4. The method of claim 3, further comprising:

deriving an upgrade identifier from the pen, wherein said given characteristic is a relation between said upgrade identifier and said upgrade reference.

5. The method of claim 1, further comprising:

storing, in a database associated with the computer system, an upgrade reference that identifies said step of providing said logic version.

6. The method of claim 5, further comprising:

providing said upgrade reference to the pen for storage therein as an upgrade identifier.

7. The method of claim 1, wherein said set is one of a plurality of different sets of processing rules, a separate logic version being created for each set, wherein each such separate logic version is created by:

deriving a full functionality logic which includes rule identifiers of all logic versions;

deriving, based on said version identifier, building instructions; and

operating said building instructions on said full functionality logic to create said separate logic version, by eliminating any rule identifier that is unsupported by being indicative of a processing rule not included in the set indicated by the version identifier.

8. The method of claim 7, wherein at least one unsupported rule identifier is eliminated by omission.

9. The method of claim 7, wherein at least one unsupported rule identifier is eliminated by being replaced by a supported rule identifier which is indicative of a processing rule included in the set indicated by the version identifier.

10. The method of claim 9, wherein said supported rule identifier indicates a processing rule for controlling the pen to give negative feedback.

11. The method of claim 9, wherein said supported rule identifier indicates a processing rule for controlling the pen to give affirmative feedback.

12. The method of claim 7, further comprising:

storing each separate logic version in a database in association with said version identifier.

13. An apparatus for communicating with an electronic pen, comprising:

an interface for communicating with said pen;

a first processing element which derives, from said pen and via said interface, a version identifier indicative of a set of processing rules stored by the pen;

a second processing element which derives, based on said version identifier, a logic version which associates pen positions with at least one rule identifier, whereby said at least one rule identifier is indicative of a processing rule in said set of processing rules; and

a third processing element which provides, via said interface, said logic version to the pen.

14. The apparatus of claim 13, wherein every rule identifier in said logic version is indicative of a processing rule in said set of processing rules.

15. The apparatus of claim 13, wherein said first processing element is designed to derive an upgrade reference from a database associated with the computer system, wherein operation of at least said third processing element to provide said logic version is conditioned by said first processing element detecting a given characteristic of said upgrade reference.

16. The apparatus of claim 15, wherein said first processing element is designed to derive, via said interface, an upgrade identifier from the pen, wherein said given characteristic is a relation between said upgrade identifier and said upgrade reference.

17. The apparatus of claim 13, wherein said third processing element is designed to store, in a database associated with the computer system, an upgrade reference that identifies an operation of providing said logic version.

18. The apparatus of claim 17, said third processing element is designed to provide, via said interface, said upgrade reference to the pen for storage therein as an upgrade identifier.

19. A method for creating a specific logic version for an electronic pen, which stores one of a plurality of different sets of processing rules, wherein a separate logic version is created for each set to comprise at least one rule identifier indicative of a processing rule in said set, said method comprising:

deriving a full functionality logic which includes rule identifiers of all separate logic versions;

deriving a version identifier indicative of a given set of processing rules;

deriving, based on said version identifier, building instructions; and

operating said building instructions on said full functionality logic to create said specific logic version, by eliminating at least one rule identifier that is unsupported by being indicative of a processing rule not included in the given set of processing rules.

20. The method of claim 19, wherein said version identifier is derived from said electronic pen.

21. The method of claim 19, wherein said specific logic version is stored in a database in association with said version identifier.

22. The method of claim 19, wherein said specific logic version is provided to the pen as a propagating signal over an electronic network.
