Abstract
A danger proximity warning system and method are disclosed that utilize ultra wideband (UWB) technology to effectively warn a person when there is a potentially dangerous situation in their vicinity. In one embodiment, the danger proximity warning system includes a transmitting UWB radio coupled to a first object and a receiving impulse radio unit coupled to a second object. The transmitting impulse radio unit operates to transmit an UWB signal towards the second object when the first object is a predetermined distance away. Upon receiving the UWB signal, the receiving UWB radio makes sure a person associated with the second object is informed about the potentially dangerous situation. Several embodiments of the danger proximity warning system and method are disclosed all of which operate to warn a person when there is a potentially dangerous situation in their vicinity.
