ABSTRACT:
A safety helmet system for motorcycle and bicycle riders includes a lightweight impact resistant helmet having an on/off switch. A power supply lights an electroluminescent strip surrounding the outer periphery of the helmet, signaling at eye level the presence of the rider to all drivers in the vicinity. The power supply also powers a single axis accelerometer having its sensitive axis oriented along the Cycle's travel direction. A microprocessor captures maximum deceleration in a braking cycle. The captured deceleration is segmented into low, medium and high values. A plurality of LED lights are mounted on the back face of the helmet. The microprocessor turns on LED arrays to create progressively increasing LED lit areas in direct proportion with the Cycle deceleration rate. Vehicle drivers following the Cycle are provided information concerning the Cycle's deceleration rate, enabling them to brake and thereby avoid colliding with the Cycle; the margin of safety is significantly increased for Cycle riders and drivers of following vehicles.
