Patent Summary

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

Class 714: Error Detection/Correction And Fault Detection/Recovery

This class provides for process or apparatus for detecting and correcting errors in electrical pulse or pulse coded data; it also provides for process or apparatus for detecting and recovering from faults in electrical computers and digital data processing systems, as well as logic level based systems.

Subclass 2: Fault recovery
Subclass 701: Data formatting to improve error detection correction capability

Class 375: Pulse Or Digital Communications

This is the generic class for pulse or digital communication systems using electrical or electromagnetic signals. Such communication includes transmitting an intelligence bearing signal from one point to another in the form of discrete variations in some parameter of the electrical or electromagnetic signal.

Subclass 222: Modems (data sets)
Subclass 230: Automatic
Subclass 232: Adaptive
Subclass 233: Decision feedback equalizer

Class 379: Telephonic Communications

(1) Systems, processes and instruments for the two-way electrical transmission of intelligible audio information having arbitrary content over a link including an electrical conductor, between spaced apart locations, so as to enable conversation therebetween, and intended for the private use of a listener or a group of listeners. The term "intelligible" used above is intended to include the capability for transmission of speech or the like (e.g., music), rather than restriction to a specified audible signal, such as a bell or buzzer. (2) Switching, signalling or signal transmission peculiar to, or specified as for a telephone or a telephone system, except for multiplex communications as indicated in Lines With Other Classes.

Subclass 93.01: Having transmission of a digital message signal over a telephone line
Subclass 93.05: Terminal interface circuitry
Subclass 406.08: Adaptive filtering
Subclass 377: Using line or loop condition detection (e.g., line circuit)
Subclass 402: Hybrid circuit

Class 370: Multiplex Communications

This is the generic class for multiplexing or duplexing systems, methods, or apparatus.

Subclass 210: Fourier transform
Subclass 217: Bypass an inoperative switch or inoperative element of a switching system
Subclass 221: Bypass an inoperative station
Subclass 230: Control of data admission to the network
Subclass 230.1: Traffic shaping
Subclass 235.1: Using leaky bucket technique
Subclass 252: Determination of communication parameters
Subclass 352: Combined circuit switching and packet switching
Subclass 392: Processing of address header for routing, per se
Subclass 395.1: Message transmitted using fixed length packets (e.g., ATM cells)
Subclass 395.52: Internet Protocol (including TCP/IP or UDP/IP) over fixed length packet network (e.g., IP over ATM)
Subclass 420: For connecting plural subscribers to a network (i.e., network termination)
Subclass 465: Adaptive
Subclass 468: Assignment of variable bandwidth or time period for transmission or reception
Subclass 474: Assembly or disassembly of messages having address headers
Subclass 484: Digital analysis or synthesis of a group
Subclass 526: Digital tone detection

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 108: Current driver
Subclass 110: Having inductive load (e.g., coil, etc.)

Class 455: Telecommunications

This is the generic class for modulated carrier wave communications not elsewhere classifiable.

Subclass 416: Call conferencing

Class 709: Electrical Computers And Digital Processing Systems: Multicomputer Data Transferring

This class provides for an electrical computer or digital data processing system or corresponding data processing method including apparatus or steps for transferring data or instruction information between a plurality of computers wherein the computers employ the data or instructions before or after transferring and the employing affects said transfer of data or instruction information. The class includes - process or apparatus for transferring data among a plurality of spatially distributed (i.e., situated, at plural locations) computers or digital data processing systems via one or more communications media (e.g., computer networks).

Class 710: Electrical Computers And Digital Data Processing Systems: Input/Output

This class provides, within a computer or digital data processing system with the following processes or apparatus for 1. transferring data from one or more peripherals to one or more computers or digital data processing systems for the latter to process, store, or further transfer or for transferring data from the computers or digital data processing systems to the peripherals; 2. for interconnecting or communicating between two or more components connected to an interconnection medium (e.g., a bus) within a single computer or digital data processing system; 3. for preventing access to a shared resource of a computer or digital data processing system; 4. for granting access to a shared resource of a computer of digital data processing system by one of a plurality of components of the computer or digital data processing system by interrogating each of the components in a predetermined order; 5. for determining which of a plurality of components of a computer or digital data processing system contending for access to a shared resource shall be granted access at any one time based upon a predetermined criteria; and 6. for stopping, halting, or suspending a current processing function within a computer or digital data processing system.

Subclass 104: System configuring
