Abstract:
A personal collision warning and protection system comprising:sensing means for transmitting a pulsed signal in a direction of travel of a person using said collision warning and protection system, said sensing means being mounted on a front portion of a jacket worn by said person; said sensing means receiving reflections of said pulsed signal, the reflections of said pulsed signal representing an obstacle in the direction of travel of said person; said sensing means 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; processing means connected to said sensing means to receive said first and said second electrical signals, said processing means processing said first and second electrical signals to generate first and second activation signals; warning means connected to said processing means to receive said first activation signal, said warning means being activated by said first activation signal to warn said person of said obstacle; protection means connected to said processing means to receive said second activation signal; said protection means including an air bag positioned on the front portion of said jacket, said protection means being activated by said second activation signal, said protection means when activated inflating said air bag to protect and prevent injury to said person when said person collides with said obstacle.
