Emergency mode for mobile devices

A mobile device, comprising:

• a memory configured to store a plurality of predefined emergency situations, a collection of recorded sonic signals indicative of voices of one or more authorized users of the mobile device, a set of phrases predetermined by a user of the mobile device, a group of phone numbers entered by the user, or a combination thereof;
• and
• circuitry configure to:
• receive sonic signals indicative of a voice of a person uttering one or more words;
• identify, based on the received sonic signals, the person as one of the authorized users of the mobile device;
• determine that the one or more words correlate with an emergency situation out of the plurality of predefined emergency situations;
• monitor changes in one or more physiological signals of the person via a separate device that the person wears, wherein the separate device is coupled with the mobile device and configured to monitor the one or more physiological signals;
• determine that the emergency situation satisfies a threshold based, at least in part, on the one or more words and utilizing the changes in the one or more physiological signals, wherein determining the emergency situation satisfies the threshold is associated with a confidence level, and wherein the confidence level is increased based on utilizing the changes in the one or more physiological signals;
• and
• perform one or more tasks, after determining that the emergency situation satisfies the threshold.

A method for operating a mobile device, comprising:

• receiving sonic signals indicative of a voice of a person uttering one or more words, the person authorized to use the mobile device;
• determining that the one or more words indicate an emergency situation based on comparing the one or more words with a list of predetermined phrases stored in the mobile device;
• monitoring, after determining that the one or more words indicate the emergency situation, changes in one or more physiological signals of the person via a separate device the person wears, wherein the separate device is coupled with the mobile device and configured to monitor the one or more physiological signals;
• determining that the emergency situation satisfies a threshold based, at least in part, on the one or more words and utilizing the changes in the one or more physiological signals, wherein determining the emergency situation satisfies the threshold is associated with a confidence level, and wherein the confidence level is increased as a result of utilizing the changes in the one or more physiological signals;
• and
• making a phone call to an emergency service and/or to a phone number stored in the mobile device for the emergency situation, wherein the phone call includes a description of the emergency situation, a geographic location of the mobile device, current time, a message requesting not to make a return call to the mobile device, or a combination thereof.
