Abstract

A rescue system includes a device that is buoyant and that has a coiled aerial which unfurls as soon as the rescue device is turned on. The rescue device transmits RF interrupted at a defined frequency. A corresponding remote receiver is tuned to the RF frequency and includes a sensor tuned to the interruption frequency.
