Abstract

A product for controlling physical properties comprising data processing means with inputs and outputs is disclosed. The product has approved bounds of behaviour. At least one of said outputs comprises at least one control signal disposed to be output by said product, and said data processing means comprises a processing control means; and a software comprising at least one application, and having a certificate uniquely associated to said at least one application. The processing control means further comprises means for confirming said at least one application by means for verifying said certificate, and means for checking functions of the application and the data processing means in co-operation such that said at least one control signal does not violate the approved bounds of behaviour of the product. A device and system comprising the product are also disclosed.

Claims

1. A product for controlling physical properties comprising data processing means with inputs and outputs, wherein said product has approved bounds of behaviour, wherein at least one of said outputs comprises at least one control signal disposed to be output by said product, and said data processing means comprises

a processing control means;

and

a software comprising at least one application, and having a certificate uniquely associated to said at least one application,

wherein said processing control means further comprises

means for confirming said at least one application by means for verifying said certificate, and

means for checking functions of the application and the data processing means in co-operation such that said at least one control signal does not violate the approved bounds of behaviour of the product.

2. The product according to claim 1, wherein said processing control means comprises hardware interfacing software and said means for confirming and checking are implemented in said hardware interfacing software.

3. The product according to claim 1, wherein said processing control means comprises hardware, wherein said means for confirming and checking are implemented in the hardware of said processing control means.

4. The product according to claim 1, wherein said means for verifying said certificate comprises a check sum calculator.

5. The product according to claim 1, wherein said means for verifying said certificate comprises hash algorithm means.

6. The product according to claim 1, wherein said processing control means comprises data base means having information on certified applications, properties of said product, and said approved bounds of behaviour.

7. The product according to claim 1, wherein said processing control means comprises communication means having access to at least one of information on certified applications, properties of said product, and said approved bounds of behaviour.

8. The product according to claim 1, wherein said processing control means comprises

communication means having access to at least one of information on certified applications, properties of said product, and said approved bounds of behaviour, and

data base means having at least one of information on certified applications, properties of said product, and said approved bounds of behaviour,

such that information on certified applications, properties of said product, and said approved bounds of behaviour are available.

9. The product according to claim 1, wherein said certificate comprises at least one of information on certified applications, properties of said product, and said approved bounds of behaviour.

10. The product according to claim 1, wherein said certificate comprises a unique identifier, time of creation, purpose of application, author, information on critical inputs, information on critical outputs, or a mark identification, or any combination thereof.

11. The product according to claim 1, comprising an output having an output signal indicating results of the checking and verification operations of said processing control means.

12. The product according to claim 1, further comprising

a second software comprising at least one application, and having a second certificate uniquely associated to said at least one application,

wherein said means for confirming is disposed for verifying said second certificate associated to said at least one application of said second software, and

said means for checking is disposed for checking functions of the application of the second software in co-operation with the application of the software and the product such that said at least one control signal does not violate the approved bounds of behaviour of the product.

13. A device comprising a product according to claim 1, disposed for controlling building related functionality.

14. The device according to claim 13, comprising a further application.

15. A system comprising a plurality of devices according to claim 13, further comprising means for defining said approved bounds of behaviour and at least one building related functionality device whose physical properties is to be controlled by at least one of said devices.

16. The system according to claim 15, wherein said at least one building related functionality device is a valve, an electric motor, a radiator, an elevator, an escalator, an actuator, a contactor, a curtain, a shutter, a blind, a louver, a dimmer, a door or gate lock, a power outlet, a camera, or a turnstile, or any combination thereof.

17. The system according to claim 15, wherein said means for defining said approved bounds of behaviour is disposed to define said bounds according to regulations of European Energy Performance of Buildings Directive.

18. The system according to claim 17, wherein said means for defining said approved bounds of behaviour is arranged to provide an EUBAC mark to said certificate.

19. A system comprising a plurality of devices according to claim 14, further comprising means for defining said approved bounds of behaviour and at least one building related functionality device whose physical properties is to be controlled by at least one of said devices.

20. The system according to claim 16, wherein said means for defining said approved bounds of behaviour is disposed to define said bounds according to regulations of European Energy Performance of Buildings Directive.
