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 functioning properly on the UDPD by determining whether the codetext of the SCA is uncorrupted, the method comprising:

executing instructions with UDPD to calculate, a host integrity check for a codetext of the SCA;

retrieving a corresponding reference host integrity check calculation;

comparing, with the UDPD, the calculated host integrity check and the retrieved corresponding reference host integrity check calculation; and

determining, with the UDPD, whether a change exists in the calculated host integrity check and the reference host integrity check.

2. The method of claim 1, wherein the reference host integrity check is a previously calculated stored host integrity check.

3. The method of claim 1, wherein the reference host integrity check is a host integrity check for the SCA in an uncorrupted state.

4. The method of claim 1, wherein the reference host integrity check is a host integrity check calculated previously during manufacturing and testing and stored in memory for later retrieval.

5. 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 calculated host integrity check and the reference host integrity check is determined.

6. 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 calculated host integrity check and the reference host integrity check is determined.

7. 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 of the calculated host integrity check and the reference host integrity check is determined.

8. The method of claim 7, wherein the safety critical features of the SCA comprises communication of the SCA with a remote device external to the UPDP.

9. The method of claim 7, wherein the safety critical features of the SCA comprises determining an analyte concentration from a bodily fluid executed on the UDPD.

10. The method of claim 1, wherein the SCA is an analyte monitoring application.

11. The method of claim 10, wherein the analyte is glucose or ketone.

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

13. The method of claim 12, wherein the hand-help data processing device is a mobile phone.

14. The method of claim 12, wherein the hand-help data processing device is a personal digital assistant (PDA).

15. The method of claim 7, wherein the safety critical features of the SCA comprises receiving data from a sensor subcutaneously implanted in a subject.

16. The method of claim 1, wherein the instructions are comprised in a test harness application installed on the UDPD.
