Title: Protection and locating system for persons
Inventor: FREISL PAUL PETER
IPC: A63B29/02
Filed: 1981-03-11
Abstract: A protection and locating system for persons, to be used for avalanche rescue in skiing, for accident prevention in industry and for the surveillance of persons. Personal electronics of all types require a power supply which is distinguished by automatic charging, unattended operation, freedom from maintenance and integration into a mandatory piece of equipment of the carrier. The present invention achieves this object with the aid of the inductive power supply system as a basic component for all applications by using stationary primary induction loops in floors and secondary induction loops in soles of shoes with rectifier, accumulator and load units located in heels of shoes. In this arrangement, alternating currents flow through primary and secondary induction loops in accordance with the transformer principle. An inside/outside shoe temperature difference switch interrupts the power supply as soon as the shoes are removed. In the field of avalanche rescue, the accumulator is charged in cable car waiting rooms, (floor induction loops) and at ski-lifts (rubber induction mats). When the wearer is buried, the transmitting (receiving) unit automatically starts to operate (darkening of the photocell) and enables the wearer to be found more quickly by means of a method similar to radio direction finding. In the accident prevention field, personal continuous transmitters can trigger alarm functions when hazardous areas are approached. Using appropriately placed frequency-selective receivers, the paths of persons can be individually monitored. <IMAGE>
