Abstract

Methods and systems for mitigating single point failure of a device in an analyte monitor. Methods include receiving, from a first device, a request for performing an operational test or to provide data related to functionality of a component of a second device, receiving a request from the first device to annunciate an alarm, and annunciating the alarm of the second device.

First claim

What is claimed is:

1. A method for mitigating single point failure of a device, comprising:
receiving, from a first device, a request for performing an operational test of a component of a second device;
performing the operational test using the second device to obtain a result; communicating the result of the operational test to the first device;
receiving a request from the first device to annunciate an alarm; and annunciating the alarm.

2. The method of claim 1 , wherein the operational test includes a digital self-test.

3. The method of claim 1 , wherein the alarm is to inform a user that the second device is not functioning properly.

4. The method of claim 1 , wherein communicating the result of the operational test to the first device is performed within a predetermined time period after receiving the request for performing the operational test.

5. The method of claim 1 , wherein the alarm includes at least one of an audible alarm, vibratory alarm or a visual alarm.

6. The method of claim 1 , wherein the second device is communicatively coupled with an in vivo sensor comprising a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

7. The method of claim 6 , wherein the analyte-responsive enzyme is chemically bonded to the polymer.

8. The method of claim 6 , wherein the working electrode further comprises a mediator.

9. The method of claim 1 , wherein the second device is communicatively coupled with an in vivo sensor comprising a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.

10. The method of claim 9 , wherein the mediator is chemically bonded to the polymer.

11. A method for mitigating single point failure of a device, comprising:
receiving, from a first device, a request for providing data related to functionality of components of a second device;
providing the data related to the functionality of the components to the first device;
receiving a request from the first device to annunciate an alarm of the second device; and
annunciating the alarm of the second device.

12. The method of claim 11 , wherein providing the data related to the functionality of the components is performed without determining the functionality of the components at the second device.

13. The method of claim 11 , wherein the alarm is to inform a user that the second device is not functioning properly.

14. The method of claim 11 , wherein providing the data related to the functionality of the components to the first device is performed within a predetermined time period after receiving the request for providing the data related to the functionality of the components.

15. The method of claim 11 , wherein the alarm includes at least one of an audible alarm, vibratory alarm or a visual alarm.

16. The method of claim 11 , wherein the second device is communicatively coupled with an in vivo sensor comprising a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

17. The method of claim 16 , wherein the analyte-responsive enzyme is chemically bonded to the polymer.

18. The method of claim 16 , wherein the working electrode further comprises a mediator.

19. The method of claim 11 , wherein the second device is communicatively coupled with an in vivo sensor comprising a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.

20. The method of claim 19 , wherein the mediator is chemically bonded to the polymer.
