  • Patent number: 4974215
    Abstract: A loading dock range finding system is provided for permitting a driver of a vehicle backing towards a loading dock to determine a distance of the back end of the vehicle from a reference point at the loading dock. An ultrasonic transmitting and receiving transducer is positioned adjacent the loading dock for sending signals towards a back end of the truck, which are reflected and received by the transducer. A display unit is connected to the transducer and is mounted at a location adjacent the loading dock so that a visual display on the display unit can be easily viewed by a driver of the vehicle looking through his rear view mirror. A distance between the back end of the vehicle and the reference point is displayed in reversed image fashion on the visual display so that when the driver views the image through his rear view mirror, it is not a reversed image.
