System and method for determining a specific user location and a path to an exit
A system and method for determining a specific user location and path to an exit during an emergency condition. In response to an emergency alarm activated for a structure, a notification system may receive the alarm signal. The notification system may send a notification of the alert to a user mobile device when the user has subscribed to receive alerts regarding the structure. The notification may determine that the subscribed mobile device is located in the vicinity of the structure and activate an alarm on the device. A distressed user's mobile device may also be configured to transmit a supersonic audio SOS signal to a responder's mobile device. The two devices may establish supersonic communications between the responder and the distressed user devices to provide instructions or guidance to locate the distressed user device.
1. A method of locating a distressed mobile device user, comprising:
receiving a notification of an emergency condition at a specified location on a mobile device;
monitoring for a supersonic audio signal on the mobile device;
activating a supersonic audio SOS signal via a user interface of the mobile device of the distressed mobile device user;
broadcasting the supersonic audio SOS signal through a device speaker of the distressed mobile device user;
detecting the supersonic audio SOS signal on a second mobile device;
broadcasting a supersonic audio acknowledgement of the SOS signal; and
presenting an audio strength meter on a display screen of the second mobile device.
2. The method of claim 1 , further comprising:
presenting a directional guidance on the display screen of the second mobile device to the source of the supersonic audio SOS signal.
3. The method of claim 1 , further comprising:
receiving the supersonic audio acknowledgement of the supersonic audio SOS signal through a device microphone of the distressed mobile device user; and
triggering a human perceptible alarm signal after receiving the acknowledgement.
4. The method of claim 3 , wherein the human perceptible alarm is one or more of an audible alarm and a visual alarm.
