702 /   HD   DATA PROCESSING: MEASURING, CALIBRATING, OR TESTING



DEFINITION

Classification: 702/

This class provides for apparatus and corresponding methods wherein the data processing system or calculating computer is designed for or utilized in an environment relating to a specific or generic measurement system, a calibration or correction system, or a testing system.

This class is structured into four main parts:

1. Data processing for a measurement system in a specific environment.

2. Data processing for a calibration or correction system.

3. Data processing for a testing system.

4. Data processing for a generic measurement system.

See Subclass References to the Current Class for these specific subclasses.

Scope of the class:

A. MEASUREMENT SYSTEM IN A SPECIFIC ENVIRONMENT This class is limited to data processing and calculating computer apparatus and corresponding methods for measuring in a specific environment. There must be significant claim recitation of the data processing system, process or calculating computer and nominal recitation of the specific environment. When significant structure of the device or process pertinent to the specific environment is claimed, classification is in the appropriate device or process class. Control system for specific application adapted for a sole purpose of measuring is classified in this class. This class does not includes data processing in combination with a specific application control system for controlling a device or apparatus (see References To Other Classes below for a generic or specific electrical computers and data processing control systems).

B. CALIBRATION OR CORRECTION SYSTEM

This class includes subject matter directed to data processing for calibration or correction system disclosed or claimed in plural art devices such as geometrical instrument, mechanical system, timing apparatus, fluid flow or fluid measurement, etc. (see References To Other Classes below).

C. TESTING SYSTEM

This class includes subject matter directed to data processing for testing system disclosed in plural art devices such as electrical circuit and components testing, sensing apparatus testing, signal converting, shaping or generating (see References To Other Classes below).

This outdent excludes a mere monitoring system for determining performance of a device or process under normal operation without subjecting the device or process to a specific testing procedure or signal.

D. GENERIC MEASUREMENT SYSTEM

This class is limited to data processing and calculating computer apparatus and corresponding methods for measuring that are not strictly adapted to one particular environment. Such apparatus and corresponding methods for measuring could extend to several different applications. There must be significant claim recitation of the data processing system, process or calculating computer. A generic control system adapted for a sole purpose of measuring is classified in this class. This class does not includes data processing in combination with a generic control system for controlling a device or apparatus (see References To Other Classes below for a generic or specific electrical computers and data processing control systems).
