Abstract:
1. A personal security apparatus, comprising: a transmitting device including a transmitter and an event detector initiating different signals wherein each of the different signals indicates a different event type, said event detector further comprising an acceleration detector, a computer and program code stored in a non-transitory computer readable medium, the event detector further including a motion detector, said motion detector comprising the computer processing at least a portion of the program code, the processed program code interprets signals from the acceleration detector and detects that the transmitting device is not being worn by a user based upon a specified threshold frequency of motion and detects that the user has fallen based upon a specified threshold and direction of acceleration and wherein a first one of the different signals initiated by the event detector based upon frequency of motion sensed by the motion detector and sent by the transmitter when the frequency of motion exceeds the specified threshold is a notification that the transmitting device is not being worn by the user and a second one of the different signals initiated by the event detector based upon direction and acceleration of motion sensed by the motion detector and sent by the transmitter when the direction and acceleration of motion exceed the specified thresholds is a notification that the user has fallen; and a remote monitoring device for receiving the signals.
