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 39: Monitor recognizes sequence of events (e.g., protocol or logic state analyzer)
Subclass 716: Loop-back

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 240.01: Television or motion video signal

Generating, processing, transmitting or transiently displaying a sequence of images, either locally or remotely, in which the local light variations composing the images may change with time.

Subclass 155: Motion detection

Class 382: Image Analysis

This is the generic class for apparatus and corresponding methods for the automated analysis of an image or recognition of a pattern. Included herein are systems that transform an image for the purpose of (a) enhancing its visual quality prior to recognition, (b) locating and registering the image relative to a sensor or stored prototype, or reducing the amount of image data by discarding irrelevant data, and (c) measuring significant characteristics of the image.
