Abstract: Recently, passenger vehicles were equipped with an Advanced Driver Assistance System (ADAS) feature in assisting drivers to control the vehicle, which gives an alarming signal about possible ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...
