Patent Summary

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

Class 385: Optical Waveguides

(1) An optical waveguiding element, which conveys light from one point to another through an optically transparent elongated structure by modal transmission, total internal reflection, or total reflectorization. (2) A combination of an optical waveguiding element with an additional broadly recited optical element which couples light or a combination. (3) A combination of an optical waveguiding element with structure which mechanically joins this waveguiding element with another or with a diverse optical element. (4) An optical modulator where the modulation of a light wave characteristic is performed exclusively within an optical waveguiding element. (5) Other miscellaneous devices formed of an optical waveguide (e.g., a waveguide sensing device) and supplemental devices which are limited to use with an optical waveguide (e.g., an external clamp or retainer).

Subclass 11: POLARIZATION WITHOUT MODULATION
Subclass 12: OPTICAL WAVEGUIDE SENSOR
Subclass 13: Including physical deformation or movement of waveguide
Subclass 14: INTEGRATED OPTICAL CIRCUIT
Subclass 16: Switch (i.e., switching from one terminal to another, not modulation)
Subclass 17: Matrix switch (i.e., M X N, where M and N are 3 or more)
Subclass 18: Reflective-type switch
Subclass 19: Stationary waveguides with movable opaque element

Class 398: Optical Communications

This class provides for all types of communication systems in which optical signals are used to transmit modulated carrier wave information between points. Such communication includes transmitting an intelligence-bearing signal from one point to another in the form of variations in a characteristic of the light wave. The communication may be through free space, fibers or waveguides. These are used to transfer the information with an optical beam, and this beam can be used in various communication schemes to enable the most effective or desired method of moving the information, including optical multiplexing when plural information signals or plural transmitters and receivers are utilized.

Subclass 106: REMOTE CONTROL
Subclass 119: Compensation
Subclass 120: Power control
Subclass 196: For wavelength control
Subclass 197: For power control
Subclass 79: Wavelength division or frequency division (e.g., Raman, Brillouin, etc.)
Subclass 82: By optical coupling
Subclass 83: Add or drop
Subclass 85: Filter
Subclass 38: Power

Class 340: Communications: Electrical

Communications - the handling of information or intelligence, restricted to the conveying of said information or intelligence between geographically spaced points. Information or intelligence is defined as being, matter which is handled by signaling systems or signaling devices (such as telegraph systems) or by that portion of nonsignaling systems or nonsignaling devices (such as power supply systems) which is designated in the arts as having a control function (such as the supervisory circuits which control the circuit breakers of an electric power network). Handling, as used above, is defined as being the active coaction between the tangible communication system or device and the intangible information or intelligence, and such coaction may assume various forms, such as transmission, storage, exhibiting, etc.

Subclass 825.72: Wireless link

Class 356: Optics: Measuring And Testing

Methods 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.
