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 wearable device for providing information to a user regarding the user'"'"'s blood glucose value, the device comprising:

a communication module having an input/output port for receiving data transmitted from a continuous glucose monitoring system including a sensor, a signal from the sensor transformed into the data for transmission, wherein the communication module is configured to receive a first dataset and a second dataset;

a display configured to display a first information based on the first dataset for a set duration; and

an input module for enabling the user to acknowledge that the first information has been viewed,

wherein when the user acknowledges that the first information has been viewed, the communication module sends an acknowledgement signal to the glucose monitoring system,

wherein the display is configured to cease displaying the first information after the continuous glucose monitoring system receives the acknowledgement signal from the communication module, and

wherein, after the set duration elapses, the display is configured to no longer display the first information until the communication module receives the second dataset from the glucose monitoring system.

2. The device of claim 1, wherein the signal is received from a computing device of the continuous glucose monitoring system.

3. The device of claim 1, wherein the computing device is a smartphone.

4. The device of claim 1, wherein the first information displayed includes at least one of a glucose value, a glucose trend, an alert, and a time when the signal was received from the continuous glucose monitoring system.

5. The device of claim 1, wherein the device further comprises a timer chip, timer circuit, or timer implemented by program instructions on a non-transitory computer-readable medium.

6. The device of claim 5, wherein the timer measures the set duration.

7. The device of claim 1, wherein the set duration begins when the data is received from the continuous glucose monitoring system.

8. The device of claim 1, wherein the display of the first information commences without any user interaction.

9. The device of claim 1, wherein a brightness of the displayed first information fades as the set duration elapses.

10. The device of claim 1, wherein the set duration is in the range of one second to twenty minutes.

11. The device of claim 1, wherein the display comprises one or more of electronic paper, electronic ink, an electrophoretic display, a gyricon, a liquid crystal display, one or more light-emitting diodes, one or more organic light-emitting diodes, a color-changing material, a pattern-changing material, magnetic materials, piezo-electric materials, vibration patterns, heat/cold patterns, one or more light pipes with single-color or multicolor light-emitting diodes or organic light-emitting diodes, a transparent and flexible multi-touch surface, or an interactive glass surface.

12. The device of claim 1, further comprising a band configured to be worn about a wrist of a wearer, wherein the communication module and the display are incorporated into the band.

13. The device of claim 1, wherein the display is further configured to display a status flag that indicates when the device last received the signal from the continuous glucose monitoring system.
