Abstract

Methods and articles of manufacture for hosting a safety critical application on an uncontrolled data processing device are provided. Various combinations of installation, functional, host integrity, coexistence, interoperability, power management, and environment checks are performed at various times to determine if the safety critical application operates properly on the device. The operation of the SCA on the UDPD may be controlled accordingly.

Claims

1. A method for executing instructions with an uncontrolled data processing device (UDPD) to determine whether a safety critical application (SCA) is installed properly on the UDPD:

executing instructions with an UDPD;

generating an image of an installed SCA component on the UDPD;

retrieving a reference installation data stored in memory of the UDPD;

comparing the generated image of the installed SCA component with the retrieved reference installation data; and

determining whether the SCA is installed properly on the UDPD based on the comparing.

2. The method of claim 1, wherein generating an image of an installed SCA component comprises generating error detection data associated with the installed SCA component.

3. The method of claim 2, wherein the comparing of the generated image of the installed SCA component with the reference installation data comprises comparing, with the UDPD, the error detection data associated with the installed SCA component error detection data in the reference installation data.

4. The method of claim 1, wherein generating an image of an installed SCA component comprises generating error correction data associated with the installed SCA component.

5. The method of claim 4, wherein the comparing of the generated image of the installed SCA component with the reference installation data comprises comparing, with the UDPD, the error correction data associated with the installed SCA component with error correct data in the reference installation data.

6. The method of claim 1, wherein generating an image of an installed SCA component comprises generating a filename associated with the installed SCA component.

7. The method of claim 6, wherein the comparing of the generated image of the installed SCA component with the reference installation data comprises comparing, with the UDPD, the filename associated with the installed SCA component with filename in the reference installation data.

8. The method of claim 1, wherein generating an image of an installed SCA component comprises generating a version number associated with the installed SCA component.

9. The method of claim 8, wherein the comparing of the generated image of the installed SCA component with the reference installation data comprises comparing, with the UDPD, the version number associated with the installed SCA component with a version number in the reference installation data.

10. The method of claim 1, wherein generating an image of an installed SCA component comprises generating a cyclic redundancy check (CRC) value associated with the installed SCA component.

11. The method of claim 10, wherein the comparing of the generated image of the installed SCA component with the reference installation data comprises comparing, with the UDPD, the CRC value associated with the installed SCA component with a CRC value in the reference installation data.

12. The method of claim 1, wherein generating an image of an installed SCA component comprises generating an error correcting code (ECC) associated with the installed SCA component.

13. The method of claim 12, wherein the comparing of the generated image of the installed SCA component with the reference installation data comprises comparing, with the UDPD, the ECC associated with the installed SCA component with a code in the reference installation data.

14. The method of claim 1, further comprising determining that the SCA is installed properly on the UDPD and permitting the SCA to operate freely on the UDPD if a match of the generated image and reference installation data is determined.

15. The method of claim 1, further comprising determining that the SCA is not installed properly on the UDPD, thereby preventing the SCA to operate freely on the UDPD, if a mismatch of the generated image and reference installation data is determined.

16. The method of claim 1, further comprising determining that the SCA is not installed properly on the UDPD, thereby disabling safety critical features of the SCA from being executed on the UDPD and enabling non-safety critical features of the SCA to be executed on the UDPD, if a mismatch is determined.

17. The method of claim 16, further comprising communicating the safety critical features of the SCA with a remote device external to the UPDP.

18. The method of claim 16, wherein the safety critical features of the SCA comprises determining an analyte concentration from a bodily fluid executed on the UDPD.

19. The method of claim 1, wherein the UDPD is a hand-held data processing device.

20. The method of claim 19, wherein the hand-help data processing device is a mobile phone.

21. The method of claim 19, wherein the hand-help data processing device is a personal digital assistant (PDA).
