A 3-piece, easily installed device is described that alerts a driver of imminent collisions. Tested for 3 years, the smart device is now ready for use by cars or trucks. The article describes the development of the device by a small Michigan family firm. A narrow-beam antenna transmits microwaves at more than 24 GHz. Beam width, about that of a truck, limits reflections from road signs, parked cars, etc. Reflections from objects higher than the front bumper are converted into an electronic signal and fed into a processor which turns on a dashboard monitor alert lignt and computes distance, difference in rate of speed between the driver and objects, and whether the diver and the objects are changing speed. If the processor determines a collision is imminent, it turns a warning light and sounds a buzzer until the driver decelerates or swerves.
