simulators regarded as teaching or training devices, which is the case if they give perceptible sensations having a likeness to the sensations a student would experience in reality in response to actions taken by him;
models of buildings, installations, or the like.
This subclass does not cover:
simulators which demonstrate, by means involving computing, the function of apparatus or of a system, which are covered by class Fulltext... Hierarchy... Expanded...G06, if no provision exists elsewhere;
components of simulators, if identifical with real devices or machines, which are covered by the relevant subclasses for these devices or machines (and not by class Fulltext... Hierarchy... Expanded...G09).
In this subclass, the following term is used with the meaning indicated:
"sign" designates a mark or indication serving to make something recognisable, the information presented being non-varying, even if it is flashing; by way of example it covers, therefore, advertising hoardings, or luminous, or light reflecting, safety arrangements. [3]
This subclass covers indicator consoles, i.e. arrangements or circuits for processing control signals to achieve the display, e.g. for the calling up, reception, storage, regeneration, coding, decoding, addressing of control signals. [3]
Contrary to subclass Fulltext... Hierarchy... Expanded...H04N, in which are classified display devices capable of representing continuous brightness value scales, this subclass is limited to devices using only a discrete number of brightness values, e.g. visible/non-visible. [3]
The visual effect may be produced by a luminescent screen scanned by an electron beam, directly by controlled light sources, by projection of light, from controlled light sources onto characters, symbols, or elements thereof drawn on a support, or by electric, magnetic, or acoustic control of the parameters of light rays from an independent source.
