Patent ID: 8610584

Claim:
A fall-down alarm system, comprising: a contact detection unit to perform contact detection to an object located on a surface of the contact detection unit and output a contact detection signal according to a detected shape of the object; a non-contact detection unit to detect life symptoms of the object through a non-contact means and output a non-contact detection signal; a fall-down evaluation unit connecting with the contact detection unit and the non-contact detection unit to receive the contact detection signal and the non-contact detection signal respectively and send a trigger signal when the non-contact detection signal indicates that the life symptoms of the object are abnormal and the contact detection signal indicates that the detected shape of the object is abnormal; and an alarm unit connecting to the fall-down evaluation unit to set off an alert message upon receiving the trigger signal for emergency assistance, wherein the contact detection unit performs the contact detection through a weight detection means and includes a plurality of weight sensing spots to form a weight sensing array to detect weight of the object and form a weight distribution on the weight sensing array in a shape to be outputted as the contact detection signal, and wherein the contact detection unit further includes an insulation sheet with a plurality of apertures formed thereon and corresponding to the weight sensing spots, a conductive sheet connecting to a power source and a plurality of multiplexers connecting to the weight sensing spots, the weight sensing spots being located correspondingly to the apertures to form the weight sensing array; through detecting the weight of the object, the weight sensing spots being pressed to complete an electrical loop with the conductive sheet through the apertures to generate an electric signal.
