169.~ Radiation, force, or waves reflected from external object or surface

DEFINITION

Classification: 180/169

Radiation, force, or waves reflected from external object or surface:

(under subclass 167) Vehicle wherein the radiation, force, or waves to which the means responds is that which is reflected from an object or a surface located remotely from the

vehicle.

SEE OR SEARCH THIS CLASS, SUBCLASS:

168, for a motor vehicle provided with means for controlling its operation, which means is responsive to electromagnetic radiation, magnetic force, or sound waves received from a source, or from an object or surface, located apart from the vehicle, and wherein the controlling means is adapted to interact with a stationary means which is of a kind whereby it describes the intended course of travel of the vehicle. While the stationary means of that subclass frequently is a conductor embedded in a pavement, it may also comprise, for example, a reflecting element on each of a series of roadside posts.
