ELECTRONIC BAR-GRAPH DIGITAL DISTANCE READ-OUT MONITOR

摘要

The read-out monitor is an electronic safety device mounted on (the rear of) a vehicle to overcome the blind spots at the rear of that vehicle whilst reversing. The device operates by the transmission of a signal from an ultrasonic transducer to a monitor within the vehicle and visible to the driver, enabling the driver to determine the (safe) distance between the vehicle and any other object behind.
