ABSTRACT:
A portable communications device (1) for wearing by a person and for use in conjunction with a Bluetooth enabled mobile phone (3) for communicating a signal indicative of the existence of an emergency to a base station comprises a pendant shaped housing (5) within which is located a first interface circuit (12) which comprises a pair of activating switches (14) operable by panic buttons (15) for facilitating inputting a signal to the device (1) indicative of the existence of an emergency. A microprocessor (18) reads signals from the first interface circuit (12) and reads the last determined position of the device from a GPS positioning circuit (8) in the housing (5), and also reads the identity of the device (1), a phone number of the base station to which a message indicative of the emergency is to be communicated and a message indicative of the emergency from a programmable memory (10). The microprocessor (18) prepares an activating signal which comprises the identity and position of the device (1), the phone number of the base station and the message, which is transmitted with a time label through a Bluetooth transmitter/receiver (20) to the mobile phone (3). The activating signal activates the mobile phone (3) to relay the data contained in the activating signal to the base station.
