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.

First claim

What is claimed is:

1. An in vivo analyte monitoring system, comprising:
an applicator, comprising:
an applicator assembly including a housing; and
a removable end cap secured to the applicator assembly; and

an on-body electronics device, comprising:
an analyte sensor, at least a portion of which is configured to be positioned in a body of a user and sense an analyte level in the body;
communication circuitry configured to receive a wireless transmission from a reader device according to a Bluetooth protocol; and
one or more processors coupled with a memory, the memory storing instructions that, when executed by the one or more processors, cause the one or more processors to:
determine whether the wireless transmission is part of a Bluetooth advertising sequence, and
in response to determining that the wireless transmission is part of the Bluetooth advertising sequence, change the state of the on-body electronics device from a first power mode to a second power mode, wherein the second power mode consumes more power than the first power mode,

wherein the applicator assembly is configured to releasably retain the on-body electronics device within an interior of the applicator assembly until the on-body electronics device is applied to a user.

2. The in vivo analyte monitoring system of claim 1 , wherein the wireless transmission is a first wireless transmission, and wherein the instructions stored in the memory, when executed by the one or more processors, cause the one or more processors to determine whether the first wireless transmission is part of the Bluetooth advertising sequence without demodulating the first wireless transmission.

3. The in vivo analyte monitoring system of claim 2 , wherein the instructions stored in the memory, when executed by the one or more processors, further cause the one or more processors to demodulate a second wireless transmission from the reader device when the on-body electronics device is in the second power mode.

4. The in vivo analyte monitoring system of claim 3 , wherein the instructions stored in the memory, when executed by the one or more processors, further cause the one or more processors to determine if the demodulated second wireless transmission contains an activation request message.

5. The in vivo analyte monitoring system of claim 4 , wherein the activation request message corresponds to a connectable directed advertising event.

6. The in vivo analyte monitoring system of claim 4 , wherein the instructions stored in the memory, when executed by the one or more processors, further cause the one or more processors to instruct the communication circuitry to transmit a confirmation response to the reader device if the demodulated second wireless transmission contains the activation request message.

7. The in vivo analyte monitoring system of claim 4 , wherein the instructions stored in the memory, when executed by the one or more processors, further cause the one or more processors to change the state of the on-body electronics device from the second power mode to the first power mode if the demodulated second wireless transmission does not contain the activation request message.

8. The in vivo analyte monitoring system of claim 1 , wherein the first power mode is a sleep mode and the second power mode is a normal operation mode.

9. The in vivo analyte monitoring system of claim 1 , wherein the Bluetooth advertising sequence comprises a series of advertising packets transmitted at a predetermined time interval.

10. The in vivo analyte monitoring system of claim 9 , wherein the Bluetooth advertising sequence is on a plurality of advertising channels.

11. The in vivo analyte monitoring system of claim 1 , further comprising the reader device.

12. The in vivo analyte monitoring system of claim 11 , wherein the reader device comprises a smart phone.

13. The in vivo analyte monitoring system of claim 11 , wherein the reader device is a wearable electronics device comprising a smart watch.

14. The in vivo analyte monitoring system of claim 1 , wherein the instructions stored in the memory, when executed by the one or more processors, further cause the one or more processors to demodulate the wireless transmission and determine if the Bluetooth advertising sequence contains an activation request message.

15. The in vivo analyte monitoring system of claim 14 , wherein the instructions stored in the memory, when executed by the one or more processors, further cause the one or more processors to instruct the communications circuitry to transmit a confirmation response to the reader device if the demodulated wireless transmission contains the activation request message.

16. The in vivo analyte monitoring system of claim 15 , further comprising the reader device, and wherein the reader device is configured to transition from an advertising state to a connection state in response to receiving the confirmation response from the on-body electronics device.

17. The in vivo analyte monitoring system of claim 14 , wherein the instructions stored in the memory, when executed by the one or more processors, further cause the one or more processors to wait a predetermined amount of time before enabling the communications circuitry to monitor for an additional wireless transmission from the reader device if the demodulated wireless transmission does not contain the activation request message.

18. The in vivo analyte monitoring system of claim 1 , wherein the Bluetooth advertising sequence comprises a connectable directed advertising code.

19. The in vivo analyte monitoring system of claim 1 , wherein the communication circuitry is configured to receive a plurality of wireless transmissions from the reader device according to the Bluetooth protocol, and wherein the instructions stored in the memory, when executed by the one or more processors, further cause the one or more processors to determine whether the plurality of wireless transmissions is part of the Bluetooth advertising sequence.

20. The in vivo analyte monitoring system of claim 19 , wherein the processor is programmed to determine whether the plurality of wireless transmissions is part of the Bluetooth advertising sequence without demodulating the plurality of wireless transmissions.
