INSTRUMENTS

|  | G06 |
COMPUTING; CALCULATING; COUNTING (score computers for games Fulltext... Hierarchy... Expanded...A63B 71/06, Fulltext... Hierarchy... Expanded...A63D 15/20, Fulltext... Hierarchy... Expanded...A63F 1/18; combinations of writing appliances with computing devices Fulltext... Hierarchy... Expanded...B43K 29/08)

|  | G06 |
Note(s) Attention is drawn to the notes (particularly the definition of the term "variable") on page 7 of this Section. In this class: The term "data" is understood to be synonymous with "information", and the term "information" is therefore not used in sub-class Fulltext... Hierarchy... Expanded...G06C or Fulltext... Hierarchy... Expanded...G06F. The terms "calculating" and "computing" are both understood to include, inter alia, operations on numerical values and on data expressed in numerical form; of these words "computing" is used throughout the class. "Computation" is derived from this interpretation of "computing". In the French language the word "calcul" will serve for either word. In those sub-classes which include simulators: a simulator in class Fulltext... Hierarchy... Expanded...G06 is concerned with the mathematics of computing the existing or anticipated conditions within the real device or system; control functions derived from simulators are not in class Fulltext... Hierarchy... Expanded...G06 but are generally in class Fulltext... Hierarchy... Expanded...G05, although they may be in the sub-class for the device controlled; measurement of an individual variable to serve as an input to a simulator is in class Fulltext... Hierarchy... Expanded...G01; a simulator is regarded as a teaching or training device proper to class Fulltext... Hierarchy... Expanded...G09 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 in class Fulltext... Hierarchy... Expanded...G06, if no provision exists elsewhere. Components of simulators, if identical with real devices or machines, are classified in the relevant sub-class for these devices or machines and not in class Fulltext... Hierarchy... Expanded...G06 or Fulltext... Hierarchy... Expanded...G09; a simulator may use the same time scale as the real device or operate on an expanded or compressed time scale; models of real devices to reduced or expanded scales are not regarded as simulators. The term "record carrier" is understood to mean a body, such as a cylinder, disc, card, tape, or wire, capable of permanently holding information, which can be read-off by a sensing element movable relative to the recorded information.

|  | G06C |
DIGITAL COMPUTERS IN WHICH ALL THE COMPUTATION IS EFFECTED MECHANICALLY (score computers for card games Fulltext... Hierarchy... Expanded...A63F 1/18; construction of keys, printing mechanisms, or other parts of general application to the typewriting or printing art Fulltext... Hierarchy... Expanded...B41; keys or printing mechanisms for special applications, see the relevant sub-class, e.g. Fulltext... Hierarchy... Expanded...G05G, Fulltext... Hierarchy... Expanded...G06K)

|  | G06C |
Note(s) Details of mechanisms covered in main groups Fulltext... Hierarchy... Expanded...G06C 9/00, Fulltext... Hierarchy... Expanded...G06C 11/00, or Fulltext... Hierarchy... Expanded...G06C 15/00, which are applicable to mechanical counters driven only through the lowest denomination, are classified in sub-class Fulltext... Hierarchy... Expanded...G06M.

|  | G06D |
DIGITAL FLUID-PRESSURE COMPUTING DEVICES

|  | G06D |
Note(s) This sub-class includes all devices in which at least one computing function is performed by hydraulic or pneumatic means.

|  | G06F |
DIGITAL COMPUTERS IN WHICH AT LEAST PART OF THE COMPUTATION IS EFFECTED ELECTRICALLY; ARRANGEMENTS FOR HANDLING DIGITAL DATA (computers in which a part of the computation is effected hydraulically or pneumatically Fulltext... Hierarchy... Expanded...G06D; self-contained input or output peripheral equipment Fulltext... Hierarchy... Expanded...G06K; impedance networks using digital techniques Fulltext... Hierarchy... Expanded...H03H)

|  | G06F |
Note(s) In this sub-class, the expression "handling" includes processing or transporting of data.

|  | G06G |
ANALOGUE COMPUTERS

|  | G06J |
HYBRID COMPUTING ARRANGEMENTS (analogue/digital conversion or vice versa Fulltext... Hierarchy... Expanded...H03K 13/00)

|  | G06J |
Note(s) A hybrid computing arrangement is one in which part of the computation is digital and part is analogue.

|  | G06K |
RECOGNITION OF DATA; PRESENTATION OF DATA; RECORD CARRIERS; HANDLING RECORD CARRIERS (postal sorting Fulltext... Hierarchy... Expanded...B07C)

|  | G06K |
Note(s) This sub-class covers marking, sensing, and conveying of record carriers, recognising characters and other data, and presenting visually or otherwise the data recognised or the result of a computation, but does not include printing per se.

|  | G06M |
COUNTING MECHANISMS; COUNTING OF OBJECTS NOT OTHERWISE PROVIDED FOR (counting by measuring volume or weight of articles to be counted Fulltext... Hierarchy... Expanded...G01F, Fulltext... Hierarchy... Expanded...G01G; computers Fulltext... Hierarchy... Expanded...Fulltext... Hierarchy... Expanded...G06C-G06J; counting electric pulses Fulltext... Hierarchy... Expanded...H03K)

|  | G06M |
Note(s) This sub-class deals with: stepping or continuously-moving mechanical counters operated through one or more inputs applied to the lowest order mechanically or electrically; counting systems involving applications of either mechanical, electrical, or electronic counters.
