 G09B

Note(s)

  1. A simulator is regarded as a teaching or training device proper to this sub-class if the simulator gives perceptible sensations having a likeness to the sensations the student would experience in reality in response to actions taken by him. Simulators which demonstrate by means involving computing, the functioning of apparatus or of a system are classified in class G06 if no provision exists elsewhere. Simulator components which are identical with real devices or machines or components thereof are classified in the relevant sub-classes for these devices or machines and not in sub-class G09B.
  2. Models of buildings, installations, or the like are covered by this sub-class.

 G09C
CODING OR CIPHERING APPARATUS FOR CRYPTOGRAPHIC OR OTHER PURPOSES INVOLVING THE NEED FOR SECRECY (secret transmission H04K; arrangements for transmitting secret digital information H04L 9/00)

 G09D
RAILWAY OR LIKE TIME OR FARE TABLES; PERPETUAL CALENDARS (calendar blocks B42D 5/04; clockwork-driven G04B; comprising computing means G06C)

 G09F
DISPLAYING; ADVERTISING; SIGNS; LABELS OR NAME-PLATES; SEALS (display cases A47F; designs or pictures characterised by special or unusual light effects, e.g. changing, B44F 1/00; disposition of road signs or traffic signals E01F 9/00; lighting in general F21; arrangements for controlling light beams G02F 1/00; visible signalling arrangements or devices G08B 5/00; traffic control systems G08G; arrangements or circuits for control of indicating devices using static means to present variable information G09G; static indicating arrangements comprising integral associations of a plurality of light sources H01J, H01K, H01L, H05B 33/12)
 G09F

Note(s)

The term "sign" is used in this sub-class to designate 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 safety arrangements such as rear reflectors. [3]


 G09G
ARRANGEMENTS OR CIRCUITS FOR CONTROL OF INDICATING DEVICES USING STATIC MEANS TO PRESENT VARIABLE INFORMATION (lighting in general F21; instruments for displaying electric variables or waveforms G01R 13/00; controlling light beams G02F 1/00; indicating of time by visual means G04B 19/00, G04C 17/00, G04G 9/00; arrangements for transferring data between computers and peripheral equipment G06F 3/00; visible signalling arrangements or devices G08B 5/00; traffic control systems G08G; display, advertising, signs G09F, e.g. static indicating arrangements comprising an association of a number of separate sources or light control cells G09F 9/00; static indicating arrangements comprising integral associations of a number of light sources H01J, H01K, H01L, H05B 33/12; circuits in pulse counters for indicating the result H03K 21/18)  [3]
 G09G

Note(s)

  1. This sub-class concerns 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. This sub-class is not concerned with the structural details of the indicating devices, such as panels or tubes per se, or assemblies of individual light sources which are classified in the relevant sub-classes, e.g. H01J, H01K, H01L, G02F, G09F, H05B[3]
  2. In contrast to sub-class H04N in which are classified display devices capable of representing continuous brightness value scales, the present sub-class is limited to devices using only a discrete number of brightness values, e.g. visible/non-visible. [3]
  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. [3]
