ABSTRACT:
A low-cost and reliable radio warning system that alerts system users of potential hazardous conditions is disclosed. The system makes use of a transmitter and at least one receiver. The transmitter generates and transmits a radio warning signal that carries a digital data sequence that includes information concerning a particular potential hazardous condition from which the transmission was initiated, such as an approaching ambulance, fire truck, bus, train, or the like. Other information, such as GPS coordinates, may also be included. Through the use of digital encoding techniques, the system's susceptibility to false alarms or "false triggers" is minimized. The radio warning signal is transmitted in burst transmissions and may use a number of signaling techniques, including spread spectrum transmission, which increases system reliability and performance even in the presence of interference or multipath distortion. System users are equipped with a receiver that receives the radio warning signal and interprets the digital data and information carried by the warning signal. The receiver alerts the system user who has received the radio warning signal of the potential hazardous condition through the use of an audible, visual or tactile alarm. Based on the simplicity of its design, the receiver is intended to be small enough to be a portable, hand held-device, or installed or mounted in a user's motor vehicle so that persons carrying the receiver and motor vehicle operators alike can be alerted of potentially hazardous conditions by receiving a radio warning signal of the present invention.
