Class 708: Electrical Computers: Arithmetic Processing And CalculatingThis is the generic class for electrical apparatus and corresponding methods for performing calculation operations. There are three main divisions: 1. electrical hybrid calculating computers; 2. electrical digital calculating computers; 3. electrical analog calculating computers.
Subclass 130: Programmable calculator
Subclass 145: Plural function key
Class 235: RegistersMachines employed for ascertaining the number of movements of various devices or machines; also, indicating devices where the purpose is to disclose the numerical extent or quantity of movement of a machine and where the device is separate and independent of the machine whose movements are to be noted; also organized machines, such as, cash-registers, fare-registers, voting machines and calculators having registering or counting devices as essential or important elements and having in addition certain other features necessary to make up the complete machines for the purposes desired.
Subclass 10: Drawer operated
Subclass 61R: CALCULATORS
Class D18: Printing And Office MachineryOrnamental designs for: typewriter or calculator; copy reproducing equipment; document handler; printing equipment; type or type face; book binding machines, printers, stapling machines and equipment; pneumatic dispatch tube or system; miscellaneous.
Class 250: Radiant EnergyThis class provides for all methods and apparatus for using, generating, controlling or detecting radiant energy, combinations including such methods or apparatus, subcombinations of same and accessories therefore not classifiable elsewhere.
Subclass 203.6: Airborne target, or spaceborne target other than the sun (e.g., star or missile)
Subclass 559.3: With alignment detection
Subclass 559.32: Measuring rate of motion or flow (change of position)
Class 356: Optics: Measuring And TestingMethods and apparatus (1) for analyzing light to measure or test its characteristics, such as intensity, color and polarization; (2) for determining the optical or nonoptical properties of materials or articles by noting, as by inspection, measurement, or test the effect produced by the materials or articles on light associated therewith; and (3) for measuring the dimensions of structures or the spatial relationships such as distances or angle bearings of spaced points by comparison of the respective properties (usually direction or spatial position) of the light from these points or by comparison of the properties of these lights with some scale or standard. The light analyzing includes or is for spectroscopy, interference, polarization, beam direction or pattern, focal position of a light source, shade or color, and photometers. The material or article properties determined are or involve crystal or gem examination, material strain analysis, blood analysis, optical pyrometers, egg candling, cutting blade sharpness, oil testing, document verification, flatness, lens or reflector testing, refraction testing, monitoring moving webs or fabrics, light transmission or absorption, light reflection, inspection for flaws or imperfections in materials, and thread counting. The dimensioning and spatial relationship determination includes triangulation by a light beam, contour plotting, range or height finders, motion stopping, velocity or velocity/height measuring, sighting where the optical element or reticle moves with the sighted object, particle size determination, particle light scattering, electrophoresis, angle measuring or axial alignment, mensuration or configuration comparison, alignment in a lateral direction, and fiducial instruments.
Subclass 400: With light detector (e.g., photocell)
