Abstract
An advanced warning system for the physically challenged, which includes a first device disposed in the vicinity of a hazard for the physically challenged and including a transmitter and an antenna disposed for transmitting radio signals warning of the presence of the hazard. The system further includes a second device located with or on the physically challenged and including a receiver adapted for receiving the warning signal from the first device and including structure for indicating to the physically challenged user that a hazard is nearby. The system may be configured to include a plurality of the first devices distributed throughout an area having an equal plurality of potential hazards. In such configuration, the system may include a central radio station adapted for sending control update signals to each of the first devices.
