Real-time Ultrasound System for Driver Monitoring: An Innovative Application

Different technologies, that include infrared radiation sensors and artificial vision, as well as radio-frequency devices, have been proposed for passenger positioning, but most are hindered by various kinds of interference, due to sources of light or heat in the environment. In addition, specialized electronic circuits are needed. In restricted spaces (e.g. aboard vehicles), monitoring can be performed at low cost with small, reliable devices. Ultrasound waves in air ,being compatible with light, temperature variations, and electromagnetic fields, are efficient under different environmental conditions and suitable for in-vehicle monitoring. In this article the authors treat the development of an ultrasonic sensor based on the ferroelectric polymer technology. A prototype of four transmitter/receiver elements is realized in order to monitor on-board driver position and movement. Results on inside positioning by implementing cross-correlation algorithms are presented and discussed. In particular, the proposed application is suitable as support for a more complex system that needs the distance knowledge of the driver from an analyzer of gas expiratory level to correctly measure its blood alcohol concentration. Moreover, passive passenger monitoring system is useful for different application such as airbags activation devices.
