Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 342: Communications: Directive Radio Wave Systems And Devices (E.G., Radar, Radio Navigation)

Systems and processes for transmission or reception of radio wave energy for obtaining or utilizing information (using radio wave transmitters or receivers), as to an object, or as to the directional characteristics of the radio wave energy, per se. his class includes radar systems wherein radio wave energy from a transmitter is reflected or otherwise returned from an object to a receiver which may be at the same location as the transmitter; includes subsystems, components, and related processes which are limited to use in connection with the above. This class is limited to electromagnetic radio frequency waves in the radiation field.
