Signalling device and communications system
First Claim
1. An emergency signalling system including an emergency communications network;
- a monitoring station having at least one server with a storage means for storing user information and a message-scheduling table, and a timer adapted to operate in real time; and
at least one emergency signalling device having a transmitter adapted to communicate with said at least one server over the communications network, and a timer adapted to operate in real time;
each said at least one emergency signalling device having setting means for selectively setting the timer thereof to initiate said at least one server or the transmitter to transmit an emergency signal at a time set by said setting means;
the monitoring station is arranged to use the server timer as a reference for schedules in said table, and each said device timer is adapted for setting by a synchronisation signal from the monitoring station so as to be in time synchronisation with the corresponding schedule in the table for transmission of an emergency signal;
the monitoring station being arranged to initiate transmission of the emergency signal at the synchronised time corresponding to any of said schedules.

Abstract
Provided is an emergency signalling device and system by which emergency signals are transmitted for reception by an emergency authority when a user set time for the transmission elapses without cancellation or reset. The device may be a telephone or a beacon. In an example the system is a digital mobile phone messaging system using a terrestrial and/or satellite based radio communications wherein the device in the form of a mobile telephone or short messaging service (SMS) capable transceiver automatically transmits an emergency or distress signal addressed to a search and rescue (SAR) or emergency service organization within a preset time interval in the event of incapacitation of the user.

30. A process for an emergency signalling system including an emergency communications network;
- a monitoring station having at least one server with storage means for storing user information and a message-scheduling table, and a timer adapted to operate in real time; and
at least one emergency signalling device having a transmitter adapted to communicate with said at least one server over the communications network, and a timer adapted to operate in real time;
each said at least one emergency signalling device having setting means for selectively setting the timer thereof;
the process comprising the steps of;(a) transmitting from any of the at least one emergency signalling device an initiation signal for transmitting an emergency signal at a time set by said setting means;
(b) on receiving the initiation signal the monitoring station uses the server timer as a reference for entering the time set for transmitting the emergency signal as a schedule in the table;
(c) transmitting a synchronisation signal from the monitoring station for setting the timer of the signalling device which transmitted the initiation signal so as to be in time synchronisation with the corresponding schedule in the table for transmission of the emergency signal; and
(d) initiating transmission of the emergency signal at the synchronised time corresponding to any of said schedules.
- a monitoring station having at least one server with storage means for storing user information and a message-scheduling table, and a timer adapted to operate in real time; and
