G01B - Definition fr

Definition statement

This subclass covers:

Instruments and methods for measuring

Relationship between large subject matter areas

The general subject matters of measuring linear dimensions, distances, or angles is covered by several subclasses besides G01B:

G01C Measuring distances, levels, or bearings, surveying; navigation; gyroscopic instruments, photogrammetry or videogrammetry.

G01S radio direction finding; radio navigation; determining distance or velocity by use of radio waves; locating or presence detecting by use of the reflection or reradiation of radio waves; analogous arrangements using other waves.

When propagation effects of waves are relevant for such measurements G01S is in general the appropriate subclass.

For measuring ground distance between points in geodesy, surveying, and navigation G01C is the appropriate subclass when no radio waves are used or when propagation effects of waves other than radio waves are not relevant.

Special rules of classification

In this subclass, the groups are distinguished by the means of measurement which is of major importance. Thus the mere application of other means for giving a final indication does not affect the classification.

Machines operated on similar principles to the hand-held devices specified in this subclass are classified with these devices.

Glossary of terms

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

Propagation effects

are relevant if the outcome of a measurement depends on the actual value of a physical quantity characterising the propagation of the wave, i.e. its wavelength, frequency, velocity, or phase. The mere presence or direction of a wave are not considered a propagation effect or to contribute to a propagation effect. To put it in another way, propagation effects are irrelevant, if the radiation may be looked upon as a beam of radiation whose wave nature can be ignored. Examples of measurements where propagation effects are relevant include e.g. measurements of propagation time, phase difference, phase delay, measurements using the Doppler effect, or interference.
