SECURITY SYSTEM COMPRISING A SELF-MIXING LASER SENSOR AND METHOD OF DRIVING SUCH A SECURITY SYSTEM |
摘要 |
A security system is described,comprising a sensor module (15) which accommodates a laser sensor(10)working with self-mixing interference. The laser sensor(10)generates measurement data which are related to the velocity of an object such as the body of a human being and,optionally,the distance between the laser sensor (10) and the object. Dependent on the measurement data assembled by the laser sensor (10)and supplied to a control circuit(30)such as an airbag computer, the airbag computer activate security means such as an airbag(35)in order to prevent injuries of the human body. Furthermore, a method of driving such a security system is described. |
