Techniques for emergency detection and emergency alert messaging

摘要

A method, apparatus, and/or system for monitoring a user and transmitting an emergency notification is disclosed. The apparatus can monitor a user's overall wellness and adherence to a therapy regimen. The apparatus can also detect a variety of emergency situations affecting the user. For example, the apparatus can detect a fall affecting the user, the activation of an emergency indicator by the user, or an emergency based on vital signs and the overall wellness of the user. The apparatus can generate and transmit an alert notification in response to determining an emergency is affecting the user. The apparatus can select the form of the alert and the network on which to transmit the alert. The apparatus can determine the form of the alert and the network based on the severity of the emergency and the strength of the networks available to the apparatus. The form of the alert and the transmission network selected can optimize the likelihood of the alert notification being successfully transmitted.

主权项

1. A wrist-worn device for facilitating emergency detection and alert transmission, the wrist-worn device, comprising:
a first sensor configured to generate elevation data that represents an elevation of the wrist-worn device; a second sensor configured to generate acceleration data that represents a magnitude of acceleration of the wrist-worn device; one or more processors; and one or memories coupled with said one or more processors, wherein the one or more processors and one or more memories are configured to: determine, based on the elevation data, an elevation of a surface; detect a fall affecting a wearer of the wrist-worn device based on the elevation data and the acceleration data; determine a signal strength of one or more communication networks available to the wrist-worn device; select a preferred communication network for transmitting an alert notification based on the signal strength of the one or more communication networks; generate the alert notification; and transmit the alert notification away from the wrist-worn device using the preferred communication network; wherein detecting the fall includes:
determining that the acceleration data satisfies a fall condition; anddetermining, based on the elevation data, that the wrist-worn device is vertically displaced from the surface by a distance that passes a threshold distance.
