Automatic alarm

In case of loss of consciousness by the user the mPhone device raise an audio visual-alarm.

The device constantly reads data from accelerometer and if it claims the phone does not move for a programmable period of time, the device raises an alarm – periodically plays back a siren sound and flashes with display backlight.

Raising the alarm can be disabled entirely or the user may choose a specific position in which the phone may be safely put away and not raise the alarm. The alarm can also be triggered remotely if the phone can be reached through the network.

Seeking for other devices

In case of collapse underground the missing person may be localised by the mPhone (that uses high frequency radio waves).

By using the main menu the user may launch an application that will seek for other mPhones, PORTAS UltraTAG’s localised around,  including received signal strength, which may be used for rough approximation of the distance between the devices.

S.O.S. button

The mPhone is equipped with an S.O.S. button which may be used in case of emergency situations in order to send an alarm. After pressing the S.O.S. button the mPhone will automatically transfer a pre-defined text message or dial a pre-defined number. Additionally the main server will immediately download from the device all the relevant data including ambient conditions and device movement during last few minutes.
