Patent Summary

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

Class 329: Demodulators

A demodulator is a device which extracts an arbitrarily varying information carrying signal from a signal formed by varying a characteristic of a repetitious electrical or electromagnetic wave of less than infrared frequency in accordance with this information carrying signal. Classification herein is broadly by the type of modulation exhibited by the input signal. Combinations with basic subject matter included in this class: a demodulator combined with perfecting structure or incorporated in other structure.

Subclass 304: PHASE SHIFT KEYING OR QUADRATURE AMPLITUDE DEMODULATOR
Subclass 310: Including logic element (e.g., logic gate or flip-flop)

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.

Class 704: Data Processing:Speech Signal Processing, Linguistics, Language Translation, And Audio Compression/Decompression

This is the generic class for apparatus and corresponding methods for constructing, analyzing, and modifying units of human language by data processing, in which there is a significant change in the data.This class also provides for systems or methods that process speech signals for storage, transmission, recognition, or synthesis of speech; and for systems or methods for bandwidth compression or expansion of an audio signal, or for time compression or expansion of an audio signal. There are three main divisions: linguistics; speech signal processing; and audio compression.

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.
