Personal collision warning and protection system

A personal collision warning and protection system comprising:

• a sensor device for transmitting a pulsed signal in a direction of travel of a person using said collision warning and protection system, said sensor device being mounted on a front portion of a jacket worn by said person;
• said sensor device receiving reflections of said pulsed signal, the reflections of said pulsed signal representing an obstacle in the direction of travel of said person;
• said sensor device processing the reflections of said pulsed signal to provide a first electrical signal indicating a relative distance of said person from said obstacle and a second electrical signal indicating a Doppler velocity for said person;
• a decision logic and control circuit connected to said sensor device to receive said first and said second electrical signals, said decision logic and control circuit processing said first and second electrical signals to generate first and second activation signals;
• a warning device connected to said decision logic and control circuit to receive said first activation signal, said first activation signal activating said warning device to warn said person of said obstacle;
• an automatic protection system connected to said decision logic and control circuit to receive said second activation signal;
• said automatic protection system including an air bag positioned on the front portion of said jacket, said second activation signal activating said automatic protection system which inflates said air bag to protect and prevent injury to said person when said person collides with said obstacle.

• a warning device connected to said decision logic and control circuit to receive said first activation signal, said first activation signal activating said warning device to warn said person of said obstacle and to allow said person a time period sufficient to avoid said obstacle by steering around said obstacle;
• an automatic protection system connected to said decision logic and control circuit to receive said second activation signal;
• and
• said automatic protection system including:
• an air bag positioned on the front portion of said jacket;
• a fluid source of compressed air for supplying compressed air to said air bag, said fluid source having an outlet port;
• and
• a normally closed solenoid valve having an inlet port connected to the outlet port of said fluid source and an outlet port connected to said air bag, said normally closed solenoid valve having an electrical input connected to said decision logic and control circuit to receive said second activation signal which opens said normally closed solenoid valve allowing said compressed air to pass through said normally closed solenoid valve to said air bag inflating said air bag to protect and prevent injury to said person when said person collides with said obstacle.
