GEOPHYSICS; GRAVITATIONAL MEASUREMENTS; DETECTING MASSES OR OBJECTS; TAGS (detecting or locating foreign bodies for diagnostic, surgical or person-identification purposes A 61 B; means for indicating the location of accidentally buried, e.g. snow-buried, persons A 63 B 29/02; investigating or analysing earth materials by determining their chemical or physical properties G 01 N; measuring electric or magnetic variables in general, other than direction or magnitude of the earth's field G 01 R; magnetic resonance arrangements in general
G 01 R 33/20) [4,6]
Notes
(1)
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 a general interest, are also classified in subclass G 01 S. [6]
(2)
In this subclass, the following term is used with the meaning indicated: [6]
-
"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 capable of generating a detectable field. [6]
(3)
In this subclass, the geophysical methods apply both to the earth and to other celestial objects, e.g. planets.
(4)
Attention is drawn to the Notes following the title of class G 01.
