Abstract

Methods and apparatus, including computer program products, are provided for remote monitoring. In some example implementations, there is provided a method. The method may include receiving, at a remote monitor, a notification message representative of an event detected, by a server, from analyte sensor data obtained from a receiver monitoring an analyte state of a host; presenting, at the remote monitor, the notification message to activate the remote monitor, wherein the remote monitor is configured by the server to receive the notification message to augment the receiver monitoring of the analyte state of the host; accessing, by the remote monitor, the server, in response to the presenting of the notification message; and receiving, in response to the accessing, information including at least the analyte sensor data. Related systems, methods, and articles of manufacture are also disclosed.

First claim

What is claimed is:

1. A method for wireless communication between computing devices of a health monitoring system, comprising:
receiving, using a gateway, a heartbeat message from a receiver of an analyte monitoring system, the heartbeat message triggering connection logic;
requesting, using the gateway, a latest analyte concentration value and a receiver time from the receiver;
identifying, using the gateway, sensor data gaps of analyte concentration data stored at a remote server;
requesting, using the gateway, one or more timeframes of sensor data from the receiver based on the identified data gaps; and
providing, using the gateway, the sensor data to the server;
wherein identifying the sensor data gaps includes reading a predetermined number of past analyte concentration values stored at the receiver, storing the read predetermined number of past analyte concentration values at the gateway, requesting analyte concentration value data from the remote server, and identifying corresponding analyte concentration values between the past analyte concentration values of the receiver and the analyte concentration value data of the remote server.

2. The method of claim 1 , further comprising:
requesting, using the gateway, manufacturing data from the receiver, wherein the manufacturing data comprises a unique identifier associated with the receiver; and
checking, using the gateway, a status of the receiver based on the manufacturing data, the checking comprising sending a message to the remote server and subsequently receiving an indication of whether the status of the receiver is valid or invalid from the remote server,
wherein the requesting of the latest analyte concentration value only occurs if the status of the receiver is valid.

3. The method of claim 1 , further comprising:
requesting, using the gateway, a universal time from the server; and
calculating, using the gateway, a drift in time based on a difference between the receiver time and the universal time,
wherein the identifying the sensor data gaps is based on the drift in time.

4. The method of claim 3 , further comprising storing the drift in a memory of the gateway.

5. The method of claim 1 , wherein triggering the connection logic includes operating an application resident on the gateway to establish a communication connection between the gateway and the receiver.

6. The method of claim 5 , wherein the gateway includes a smartphone or tablet.

7. The method of claim 5 , wherein triggering the connection logic includes initiating a radio connection procedure when the application is running in a background mode or is shut down on the gateway.

8. A health monitoring system, comprising:
a receiver configured to receive analyte data from an analyte sensor; and
a communication gateway including one or more processors and non-transitory computer instructions stored in memory and executable by the one or more processors, the instructions comprising:
receiving, a heartbeat message from the receiver, the heartbeat message triggering connection logic,
requesting a latest analyte concentration value and a receiver time from the receiver,
identifying sensor data gaps of analyte concentration data stored at a server,
requesting, one or more timeframes of sensor data from the receiver based on the identified data gaps, and
providing the requested sensor data to the server,
wherein instructions for identifying the sensor data gaps includes reading a predetermined number of past analyte concentration values stored at the receiver, storing the read predetermined number of past analyte concentration values at the gateway, requesting analyte concentration value data from the remote server, and identifying corresponding analyte concentration values between the past analyte concentration values of the receiver and the analyte concentration value data of the remote server.

9. The system of claim 8 , wherein the instructions further comprise:
requesting manufacturing data from the receiver, wherein the manufacturing data comprises a unique identifier associated with the receiver; and
checking a status of the receiver based on the manufacturing data, the checking comprising sending a message to a remote server and receiving an indication of whether the status of the receiver is valid or invalid,
wherein the requesting of the latest analyte concentration value only occurs if the status of the receiver is valid.

10. The system of claim 8 , wherein the instructions further comprise:
requesting a universal time from the server; and
calculating a drift in time based on a difference between the receiver time and the universal time,
wherein the identifying the sensor data gaps is based on the drift in time.

11. The system of claim 10 , wherein the instructions further comprise storing the drift in the memory of the communication gateway.

12. The system of claim 8 , wherein triggering the connection logic includes operating an application resident on the gateway to establish a communication connection between the gateway and the receiver.

13. The system of claim 12 , wherein the communication gateway includes a smartphone and/or tablet comprising the one or more processors and memory storing the instructions.

14. The system of claim 13 , wherein the communication gateway further includes a docking station in communication with the smartphone and/or tablet and configured to physically and communicatively couple to the receiver.

15. The system of claim 12 , wherein the instructions for triggering the connection logic includes instructions comprising initiating a radio connection procedure when the application is running in a background mode or is shut down on the communication gateway.
