16SUPPLIED OR CONTROLLED BY SPACE-TRANSMITTED ELECTROMAGNETIC OR ELECTROSTATIC ENERGY (E.G., BY RADIO)


DEFINITION

Classification: 318/16

(under the class definition) Subject matter in which the electric motor is supplied with and/or controlled by electric space-transmitted electromagnetic or electrostatic energy. (e.g., radio energy).

(1) Note. Unitary or structurally organized devices commonly known as electromagnets, electric motors, electrostatic motors, etc., in which an air gap or a displaceable dielectric or nonmagnetic substance is present and across which electromagnetic or electrostatic lines of force extend to an armature thereof, are not included in the above recited means.

(2) Note. The magnitude of the distance between the transmitter of energy or signals and the receiver is not

critical since they may be separated merely by a thin membrane, a wall between rooms, or miles between stations.

480, and the subclasses specified in the Notes to the definition of that subclass for motor systems within the class definition which are controlled by radiant energy, other than electromagnetic or electrostatic energy.

SEE OR SEARCH CLASS 191, Electricity: Transmission to Vehicles,

10, for electrical transmission to vehicles by magnetic induction.

244, Aeronautics,

175+, is the generic subclass for systems and apparatus for automatically controlling the steering of a mobile device in two or three dimensions by electrical means, including such control systems which utilize radiant energy. See the Notes to the definition of that subclass for the other classes which provide for systems and apparatus for the control of the steering or motion of mobile devices and for a statement as to the lines between the classes.

334, Tuners,

9, for a remote controlled variable tuner having an electromagnetic operator.

340, Communications: Electrical,

825.69, and 825.72 are the generic subclasses for systems for the control of apparatus and devices at a distance by means of radio wave energy.

342, Communications: Directive Radio Wave Systems and Devices (e.g., Radar, Radio Navigation),

61+, for radio wave signal control if reflected or otherwise returned (e.g., radar) energy is utilized; subclasses 422+ provides for direction finding receivers having movable antennas which are orientated in the direction of the received signal by means of an electric motor system. See the search notes in Class 342 for other subclasses and classes which provide for radiant energy systems for controlling apparatus and devices.
