Abstract

Systems, devices, and methods are provided for changing the power state of a sensor control device in an in vivo analyte monitoring system in various manners, such as through the use of external stimuli (light, magnetics) and RF transmissions.

Claims

1. An apparatus for the continuous glucose monitoring of a user, comprising:

a sensor control device operable with an analyte sensor that is insertable into the body of the user, the sensor control device comprising;

analyte monitoring circuitry adapted to process data received from the analyte sensor;

a processor communicatively coupled with the analyte monitoring circuitry; and

an activation circuit comprising an optical activation sensor coupled with the processor, the activation circuit being adapted to, upon the sensing of optical light by the optical activation sensor, connect a power supply to the processor to supply power to the processor and allow the processor to initiate operation.

2. The apparatus of claim 1, wherein the optical activation sensor is an optically activatable switch that permits the flow of current therethrough upon sensing optical light.

3. The apparatus of claim 1, wherein the optical activation sensor is a photodiode or phototransistor.

4. The apparatus of claim 1, wherein the sensor control device comprises the power supply.

5. The apparatus of claim 4, wherein the processor performs an initiation routine upon being connected to the power supply and causes the activation circuit to bypass the optical activation sensor to continue receipt of power from the power supply.

6. The apparatus of claim 1, further comprising an applicator coupled with the sensor control device for applying the sensor control device to the user, the applicator having a cover adapted to prevent the optical activation sensor from exposure to optical light.

7. The apparatus of claim 6, wherein the cover is an end cap removably attachable to the applicator.

8. The apparatus of claim 7, wherein the sensor control device is housed within the applicator and the end cap is adapted to cover an opening in the applicator through which the sensor control device is deployable.

9. The apparatus of claim 1, wherein the optical activation sensor is housed within the sensor control device adjacent to a transparent or semi-transparent window in a housing of the sensor device.

10. The apparatus of claim 9, wherein the sensor control device comprises a surface substantially completely covered with adhesive for coupling the sensor control device to the user, a portion of the surface being free of adhesive to permit passage of optical light through the window.

11. The apparatus of claim 1, further comprising a Bluetooth transmitter.

12. The apparatus of claim 1, wherein the sensor control device interprets sensed analyte data to determine whether an alarm condition is present.

13. The apparatus of claim 1, further comprising the analyte sensor.

14. A method of preparing a sensor control device for continuous analyte monitoring for a user, comprising:

removing a cover from an applicator housing the sensor control device; and

exposing an optical activation sensor to optical light such that the optical activation sensor initiates activation of a processor in the sensor control device.

15. The method of claim 14, wherein the optical activation sensor is housed within the sensor control device.

16. The method of claim 14, wherein the cover is an end cap.

17. The method of claim 14, further comprising verifying initiation of the electronics using a reader device.

18. The method of claim 14, wherein upon exposure to optical light, the optical activation sensor permits a power supply to supply power to activate the processor.

19. The method of claim 18, wherein the processor, when activated, bypasses the optical activation sensor to maintain supply of power to the electronics.

20. The method of claim 14, wherein the analyte is glucose.
