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.
