Abstract

Methods and devices may be used to remotely hushing an event notification by receiving, from a sensor of the electronic device, an indication that a measured level has surpassed a notification threshold. In response to the indication, generating an advertising packet including an event notification for broadcast over a low power wireless point-to-point communication protocol and communicating the advertising packet including the event notification over the low power wireless point-to-point communication protocol.

First claim

The invention claimed is:

1. A non-transitory, tangible, and computer-readable medium storing instructions executable by one or more processors of an electronic device that configure the one or more processors to:
receive, from a sensor of the electronic device, an indication that a measured level has surpassed a notification threshold;
generate an advertisement packet including an event notification for broadcast over a low power wireless point-to-point communication protocol;
communicate the advertisement packet including the event notification over the low power wireless point-to-point communication protocol;
receive a hush request from a remote device to suppress the event notification;
determine whether the hush request is valid by determining whether the hush request is signed with a hush signature that is based at least upon authorization credentials shared via a remote service; and
if the hush request is valid, suppress the event notification.

2. The non-transitory, tangible, and computer-readable medium of claim 1 , wherein the instructions configure the one or more processors to communicate an audible notification when the measured level has surpassed the notification threshold.

3. The non-transitory, tangible, and computer-readable medium of claim 2 , wherein the instructions configure the one or more processors to alter the audible notification in response to receiving the hush request.

4. The non-transitory, tangible, and computer-readable medium of claim 1 , wherein:
the low power wireless point-to-point communication protocol comprises a Bluetooth Low Energy (BLE) communication protocol; and
the instructions configure the one or more processors to connect to the remote device via a wireless network comprising an 802.11 network or an 802.15.4 network.

5. The non-transitory, tangible, and computer-readable medium of claim 1 , wherein the instructions configure the one or more processors to propagate the event notification to other devices to cause the other devices to initiate a remote event notification that indicates that an event has occurred near the sensor.

6. The non-transitory, tangible, and computer-readable medium of claim 1 , wherein the instructions configure the one or more processors to add a critical service universally unique identifier (UUID) to the advertisement packet that enables the connection between the electronic device and the remote device.

7. The non-transitory, tangible, and computer-readable medium of claim 1 , wherein the instructions configure the one or more processors to broadcast a default advertisement packet using a broadcasting rate at a default rate prior to receiving the indication that the measured level has surpassed the notification threshold or after the measured level has decreased below the notification threshold.

8. The non-transitory, tangible, and computer-readable medium of claim 7 , wherein the instructions configure the one or more processors to increase the broadcasting rate of the event notification after receiving the indication that the measured level has surpassed the notification threshold and has not decreased below the notification threshold.

9. An electronic device comprising:
a sensor;
one or more processors; and
memory storing instructions executable by the one or more processors to configure the one or more processors to:
receive, from the sensor, an indication that a measured level has surpassed a notification threshold;
generate an advertisement packet including an event notification for broadcast over a low power wireless point-to-point communication protocol;
communicate the advertisement packet including the event notification over the low power wireless point-to-point communication protocol;
receive a hush request from a remote device to suppress the event notification;
determine whether the hush request is valid by determining whether the hush request is signed with a hush signature that is based at least upon authorization credentials shared via a remote service; and

if the hush request is valid, suppress the event notification.

10. The electronic device of claim 9 , wherein the instructions configure the one or more processors to:
if the hush request is valid, send a response to the remote device indicating that the hush has been completed; and
if the hush request is not valid, send a response to the remote device indicating that a hush cannot be completed because an authorization error occurred.

11. The electronic device of claim 9 , wherein the instructions configure the one or more processors to:
generate a challenge code to verify a proximity of the electronic device to the remote device;
broadcast the challenge code;
determine whether the hush signature is based at least in part on the challenge code; and
if the hush signature is based at least in part on the challenge code, suppress the event notification.

12. The electronic device of claim 11 , comprising an audio speaker, and wherein the instructions configure the one or more processors to cause the audio speaker to broadcast the challenge code as a sonic signal that includes a value that is generated after receiving the indication that the measured level has surpassed the notification threshold.

13. A method for hushing an event notification comprising:
receiving, from a sensor of a device, an indication that a measured level has surpassed a notification threshold;
generating an advertisement packet including an event notification for broadcast over a low power wireless point-to-point communication protocol;
communicating the advertisement packet including the event notification over the low power wireless point-to-point communication protocol;
receiving a hush request to suppress the event notification;
propagating the hush request to other devices;
propagating the event notification as remote event notifications to the other devices, prior to the propagating the hush request, to cause the other devices to indicate that an event has occurred at the device; and
propagating the hush request even when the event notification is unhushable, the hush request being configured to hush the remote event notifications at the other devices without hushing the device.

14. The method of claim 13 , comprising identifying the event notification as unhushable if the measured level exceeds an unhushable level for a measurement type corresponding to the sensor, if the measurement type matches an unhushable type, if the event notification has previously been hushed, or if a remote device is not proximal to the device, or any combination thereof.

15. The method of claim 14 comprising updating the advertisement packet from a default advertisement packet by including an event notification data chunk that includes an indication of an event notification type, an event severity, and that the event notification is unhushable if the event notification is identified as an unhushable event notification.

16. The method of claim 13 , comprising:
suppressing the event notification in response to the hush request; and
updating the advertisement packet with an indication that the device is currently in a hushed state.

17. The method of claim 16 , comprising:
determining that a hushed period has elapsed since the receiving the hush request;
after the hushed period has elapsed, determining whether the measured level is still above the notification threshold;
if the measured level is still above the notification threshold, unhush the event notification and rebroadcast the advertisement packet; and
if the measured level is b
