Abstract

Aspects of the subject matter described in this disclosure can be implemented in electronic medical devices, wireless gateway devices, and remote database systems in a network environment where wireless connections are made between at least an electronic device and a wireless gateway device, and between the wireless gateway device or an access point and a remote database system. The electronic medical device, the wireless gateway device, or the remote database system may be configured to identify a data communication loss based on at least a mismatch of a confirmation acknowledgement attribute between two or more nodes in the network environment. Upon identifying the data communication loss, a notification can be provided to an entity such as a user so that data communication can be restored.

First claim

What is claimed is:

1. An electronic device, comprising:
a radio-frequency (RF) communications circuitry;
one or more sensors configured to measure and/or collect biometric data; and
a control system coupled to the RF communications circuitry, the control system configured to:
transmit the biometric data from the electronic device to a wireless gateway device in a first wireless connection, wherein the wireless gateway device is configured to upload the biometric data to a remote database system;
identify a data communication loss based at least on a mismatch of a confirmation acknowledgement attribute between two or more of: the electronic device, the wireless gateway device, or the remote database system, wherein the control system is configured to identify the data communication loss while a wireless connection is available and active between the two or more devices for which the data communication loss has occurred; and
provide a notification indicating the data communication loss.

2. The electronic device of claim 1 , wherein the control system is configured to identify the data communication loss while a wireless connection is available and active between the remote database system and the wireless gateway device.

3. The electronic device of claim 1 , wherein the control system is configured to identify the data communication loss while the electronic device and the wireless gateway device are wirelessly paired.

4. The electronic device of claim 1 , wherein the wireless gateway device is configured to upload the biometric data to the remote database system in a second wireless connection, the second wireless connection provided over a wireless local area network (WLAN) and the first wireless connection provided over a personal area network (PAN).

5. The electronic device of claim 1 , further comprising:
a feedback component coupled to the control system, wherein the control system is configured to provide the notification through the feedback component by a visual notification, audible notification, haptic notification, or combinations thereof.

6. The electronic device of claim 1 , wherein the wireless gateway device comprises an access point, wireless communications hub, mobile phone, smartphone, tablet, PDA, laptop computer, desktop computer, smart watch, or smart clothing.

7. The electronic device of claim 1 , wherein the confirmation acknowledgement attribute includes a sequence identification number.

8. The electronic device of claim 7 , wherein the control system configured to identify the data communication loss based at least on a mismatch of the sequence identification number is further configured to:
cause an initial sequence identification number in a SYN flag to be transmitted with the biometric data from a source node, wherein the source node comprises the electronic device or the wireless gateway device; and
determine a mismatch with the initial sequence identification number in an ACK flag transmitted from a destination node, wherein the destination node comprises the wireless gateway device or the remote database system.

9. The electronic device of claim 7 , wherein the control system is further configured to:
cause an acknowledgement packet appended with an initial sequence identification number to be transmitted from a source node, wherein the source node includes the electronic device, the wireless gateway device, or the remote database system; and
cause a duplicated acknowledgement packet appended with the initial sequence identification number and one or more previously received sequence identification numbers to be transmitted from the source node.

10. The electronic device of claim 1 , wherein the confirmation acknowledgement attribute includes a timestamp.

11. The electronic device of claim 10 , wherein the control system configured to identify the data communication loss based at least on a mismatch of the timestamp is further configured to:
determine that a received timestamp received by a source/destination node is not greater than a previously provided timestamp from the source/destination node, wherein the source/destination node comprises the electronic device, the wireless gateway device, or the remote database system.

12. The electronic device of claim 1 , wherein the confirmation acknowledgement attribute includes a maximum segment size.

13. The electronic device of claim 12 , wherein the control system configured to identify the data communication loss based at least on a mismatch of the maximum segment size is further configured to:
determine that a received maximum segment size received by a destination node is different than a specified maximum segment size provided by a source node, wherein the source node comprises the electronic device or the wireless gateway device and the destination node comprises the wireless gateway device or the remote database system.

14. A gateway device comprising:
a radio-frequency (RF) communications circuitry; and
a control system coupled to the RF communications circuitry, the control system configured to:
connect the gateway device wirelessly with an electronic device configured to measure and/or collect biometric data;
receive the biometric data from the electronic device;
transmit the biometric data to one or more access points or a remote database system;
identify a data communication loss based at least on a mismatch of a confirmation acknowledgement attribute between two or more of: the electronic device, the gateway device, the one or more access points, or the remote database system, wherein the control system is configured to identify the data communication loss while a wireless connection is available and active between the two or more devices for which the data communication loss has occurred; and
provide a notification indicating the data communication loss.

15. The gateway device of claim 14 , wherein the confirmation acknowledgement attribute is selected from a group consisting of: a sequence identification number, a timestamp, and a maximum segment size.

16. The gateway device of claim 14 , wherein the control system configured to provide the notification indicating the data communication loss is configured to:
provide the notification via email, text message, multimedia message, or mobile app message.

17. A database system comprising:
a radio-frequency (RF) communications circuitry; and
a control system coupled to the RF communications circuitry, the control system configured to:
connect the database system wirelessly with a gateway device, wherein the gateway device is configured to receive biometric data measured and/or collected by an electronic device;
receive the biometric data from the gateway device;
identify a data communication loss based at least on a mismatch of a confirmation acknowledgement attribute between two or more of: the electronic device, the gateway device, one or more access points, or the database system, wherein the control system is configured to identify the data communication loss while a wireless connection is available and active between the two or more devices for which the data communication loss has occurred; and
provide a notification indicating the data communication loss.

18. The database system of claim 17 , wherein the confirmation acknowledgement attribute is selected from a group consisting of: a sequence identification number, a timestamp, and a maximum segment size.

19. The database system of claim 17 , wherein the control system configured to provide the notification i
