G01V - Definition fr

Definition statement

This subclass covers:

Methods and apparatus for geophysical purposes such as

Prospecting or detecting of masses or objects in general, e.g. by seismic, electric, magnetic, gravimetric, or optical means, or by the use of nuclear radiation;

Measuring gravitational fields or waves in general, e.g. gravitational forces between two bodies, or gravitational waves of cosmic origin;

Manufacturing, calibrating, cleaning, or repairing such apparatus;

Tags attached to, or associated with, an object, in order to enable detection of the object.

In this subclass, the geophysical methods apply both to the earth and to other celestial objects, e.g. planets.

Relationship between large subject matter areas

The general subject matters locating or detecting of masses or objects are covered by several subclasses besides G01V: G01SG01C.

This subclass covers radar, sonar, lidar or analogous systems specifically designed for geophysical use. Radar, sonar, lidar or analogous systems, or details of such systems, if of general interest, are also classified in subclass G01S.

References relevant to classification in this subclass

This subclass does not cover:

Means for indicating the location of accidentally buried, e.g. snow-buried, persons

A63B 29/02

Locating or presence-detecting by the use of radio, acoustic or other waves involving reflection and reradiation of waves

G01S

Burglar, theft, or intruder alarms actuated by interference with electromagnetic radiation or fields.

G08B 13/18, G08B 13/24
Examples of places where the subject matter of this class is covered when specially adapted, used for a particular purpose, or incorporated in a larger system:

Detecting or locating foreign bodies for diagnostic, surgical or person-identification purposes

A61B

Informative references

Attention is drawn to the following places, which may be of interest for search:

Survey of boreholes or wells

E21B 47/00

Investigating or analysing earth materials by determining their chemical or physical properties

G01N

Measuring electric or magnetic variables in general, other than direction or magnitude of the earth's field

G01R

Magnetic resonance arrangements in general

G01R 33/20

Glossary of terms

In this subclass, the following terms or expressions are used with the meaning indicated:

tags

means arrangements cooperating with a detecting field, e.g. near field, and designed to produce a specific detectable effect; "tags" also means active markers or labels capable of generating a detectable field; tags are not to be confused with transponders (cf Glossary of G01S).

Synonyms and Keywords

In patent documents the expressions "electronic label" or "electronic marker" is often used instead of "tag" which is used in the classification scheme of this subclass.
