A communications terminal facilitates signaling emergency alerts and monitoring. The terminal is operative in response to user input to generate emergency messages which are transmitted to one or more predetermined recipients via one or more mediums of communication. This user input to generate an emergency is designed such that it takes advantage of the facilities of available common user terminals (e.g. mobile phones, personal digital assistants) and may be augmented by short-range wireless panic button devices carried or worn by the user to allow triggering an alarm more effectively and/or conveniently. In response to either direct input from a user or remote input from another, the terminal also transmits audio, video, still image, and other available data that facilitates situation monitoring. The user may also indicate the nature and severity of the situation. Further, the terminal may suppress indications of the established communications such that the terminal appears to be in a dormant state. Further, the terminal may suppress normal handset controls allowing anyone to terminate communication, requiring specific, unique user input to terminate the emergency communication medium(s). Incorrect entry of this unique user input may be used as an indication that the user is in a situation of duress.

A method includes receiving initial sensor data and additional sensor data; and generating combined sensor data. A computing device for includes one or more processors; and one or more memories coupled to the one or more processors, the one or more memories including non-transitory computer executable instructions stored therein that, when executed by the one or more processors, cause the one or more processors to: receive initial sensor data and additional sensor data; and generate combined sensor data. A computer readable storage medium includes non-transitory computer readable instructions stored thereon for generating data regarding a vehicle crash, wherein the instructions when executed on one or more processors cause the one or more processors to: receive initial sensor data and additional sensor data; and generate combined sensor data.

A computer-implemented method for generating data regarding a vehicle crash of a vehicle can include receiving, using one or more processors of a mobile computing device within the vehicle, initial sensor data, and determining, using the one or more processors, that the initial sensor data includes sensor data indicating that the vehicle crash has occurred. The method also can include, in response to the determining, receiving additional sensor data for a first amount of time; and generating, using the one or more processors, combined sensor data that (i) is based on the initial sensor data and the additional sensor data and (ii) includes first sensor data corresponding to a first period of time before the vehicle crash of the vehicle and second sensor data corresponding to a second period of time after the vehicle crash of the vehicle. Other embodiments are disclosed.
