Patent Summary

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

Class 327: Miscellaneous Active Electrical Nonlinear Devices, Circuits, And Systems

This is the residual class for electrical devices, circuits or systems having an output not directly proportional to its input and comprising at least one component which can provide gain or can route electrical current and which device, circuit or system does not form a complete system such as is classified specifically elsewhere or a subcombination of utility only in such elsewhere classified system.

Subclass 109: Having semiconductive load
Subclass 170: Slope control of leading or trailing edge of rectangular (e.g., clock, etc.) or pulse waveform
Subclass 291: Clock or pulse waveform generating
Subclass 304: With inductive device (e.g., transformer, etc.)
Subclass 514: Light

Class 315: Electric Lamp And Discharge Devices: Systems

Electric lamp and electric space discharge device systems: structural combinations with circuit elements; structural combinations with heating and/or cooling means; cathode-ray tubes; lamps and/or discharge devices as sole load devices; lamps; electric space discharge devices gas or vapor discharge devices; high vacuum-type discharge devices, and gas or vapor-type discharge devices claimed broadly; plural load device systems; art uses and combinations with art devices; testing electric lamps and discharge devices; and operating a lamp or a gas or vapor discharge device.


Class 250: Radiant Energy

This 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 551: Signal isolator
Subclass 552: Solid state light source

Class 362: Illumination

Means and processes for casting visible radiant energy in at least one direction to render objects in that direction visible.


Class 438: Semiconductor Device Manufacturing: Process

This class provides for manufacturing a semiconductor containing a solid-state device for the following purposes: (a) conducting or modifying an electrical current, (b) storing electrical energy for subsequent discharge within a microelectronic integrated circuit, or (c) converting electromagnetic wave energy to electrical energy or electrical energy to electromagnetic energy. Also operations involving: (1) coating a substrate with a semiconductive material, or (2) coating a semiconductive substrate or substrate containing a semiconductive region. It also provides for operations involving etching a semiconductive substrate or etching a substrate containing a semiconductive region. The class provides for packaging or treatment of packaged semiconductor.

Subclass 29: Including integrally formed optical element (e.g., reflective layer, luminescent material, contoured surface, etc.)
Subclass 39: Mesa formation
Subclass 605: Multilayer electrode

Class 345: Computer Graphics Processing And Selective Visual Display Systems

Processes and apparatus for selective electrical control of two or more light-generating or light-controlling display elements* in accordance with a received or stored image data signal. The image data includes character, graphical information or display attribute data. The image data may include, for example, information data from a peripheral input device, from the reception of a television signal, from the recognition of image data, or from the generation or creation of image data by a computer.

Subclass 46: Light-emitting diodes
