Abstract
An emergency signaling system (10) is provided for simultaneously reflecting electromagnetic energy in two distinct bandwidths of the electromagnetic spectrum. The inflatable bladder (20) includes a first portion (22,24) reflective of electromagnetic energy in a visual portion of the electromagnetic spectrum, and a second portion (30) being reflective of electromagnetic energy external the visual portion of the electromagnetic spectrum. Inflatable bladder (20) is depolyed by applying a pulling force to the lanyard cord (50) which triggers release of a lighter-than-air gas from a cartridge (90). The expansion of the inflatable bladder (20) causes the closure flap (62) of the storage case (61) to be unlatched from the front wall (67), allowing the inflated bladder to ascend therefrom. Inflatable bladder (20) is tethered to the storage case (60) by way of a cord (50), the cord (50) being unwound from the cord storage assembly (70) of storage case (60).
