Abstract

“Zero-click” viewing of sensor data without any user input is provided. A display with sensor data may be “always on,” and may enable discrete viewing of sensor data without significant user hassle. Also, a system may be configured to display only current data, and/or to display the most current data for only a set interval. Also, one device in a continuous analyte monitoring system may be designated as a primary device, or hub, for receiving sensor data, and may control the flow of information and/or alerts to other devices in the system. Sensor data and/or alerts may be sent to a hierarchy of devices and/or persons in a designated order.

Claims

1. A method of providing information to a user regarding the user'"'"'s blood glucose value, the method comprising:

determining a hierarchy of a plurality of devices, wherein the plurality of devices include a first electronic device, a second electronic device, and a third electronic device;

transmitting a first signal to the first electronic device using a continuous analyte monitoring system, the first signal comprising alert and/or glucose value information;

if an acknowledgment of the first signal is not received within a first preset time limit, transmitting a second signal to the second electronic device, the second signal comprising the alert and/or glucose value information or an updated version of the alert and/or glucose value information; and

if an acknowledgement of the second signal is not received within a second preset time limit, transmitting a third signal to the third electronic device, the third signal comprising the alert and/or glucose value information or an updated version of the alert and/or glucose value information.

2. The method of claim 1, wherein the acknowledgement comprises detecting user input indicative of the user receiving the alert and/or glucose value information.

3. The method of claim 1, wherein the information is displayed on a display of the first electronic device or an audible or vibratory alert is programmatically triggered by the first electronic device responsive to the information.

4. The method of claim 2, wherein the user input comprises one or more of a user selecting a prompt on a touch sensitive screen of the first electronic device, a user depressing a button on the first device, the first electronic device detecting a predefined user motion of the first electronic device and the first electronic device detecting predefined a retinal characteristic of the user.

5. The method of claim 2 wherein the first electronic device is a smart phone.

6. The method of claim 2, wherein the first device is a smart watch.

7. The method of claim 1, wherein the second signal is specifically directed to a second electronic device.

8. The method of claim 7, wherein the second signal is generated and transmitted using the continuous analyte system, and wherein the first electronic device is configured to generate and transmit an acknowledgement signal to the continuous analyte system responsive to detecting user acknowledgement of the information.

9. The method of one of claim 7, wherein the second signal is generated and transmitted using the first electronic device.

10. The method of claim 7, further comprising the second electronic device displaying information based on the received second signal.

11. The method of claim 1, wherein the second electronic device is a smart phone.
