ABSTRACT:
A flexible safety belt which may be easily worn about the waist of a pedestrian or runner is disclosed. The belt includes an arrangement for fastening the ends together and a plurality of light-emitting diodes disposed along the outer surface of the belt. A pair of oscillators having distinct different frequencies are connected to each of a respective pair of nodes between which all of the diodes are connected. The diodes are connected so that the lower frequency oscillator conditions a set of diodes to be flashed by the output of the higher frequency oscillator when the low frequency oscillator is in one state and the balance of the diodes to be flashed by the high frequency oscillator when the lower frequency oscillator output is in the opposite state. The electronic circuitry is all constructed on a flexible circuit board disposed within the hollow interior of the belt, with the circuitry also preferably including a separately controllable alarm means.
