For example, information, (e.g. a set of figures) may be displayed for the purpose of education or advertising (<class-ref scheme="cpc">G09</class-ref>), for enabling the result of a measurement to be known (<class-ref scheme="cpc">G01</class-ref>), for signalling the information to a distant point or for giving information which has been signalled from a distant point (<class-ref scheme="cpc">G08</class-ref>); the words used to describe the purpose depend on features which may be irrelevant to the form of the apparatus concerned - such features as the desired effect on the person who sees the display or whether the display is controlled from a remote point. Again, a device which responds to some change in a condition, e.g. in the pressure of a fluid, may be used, without modification of the device itself, to give information about the pressure (<class-ref scheme="cpc">G01L</class-ref>) or about some other condition connected with the pressure (another subclass of <class-ref scheme="cpc">G01</class-ref>, e.g. <class-ref scheme="cpc">G01K</class-ref> for temperature), to make a record of the pressure or of its occurrence (<class-ref scheme="cpc">G07C</class-ref>), to give an alarm (<class-ref scheme="cpc">G08B</class-ref>), or to control some other apparatus (<class-ref scheme="cpc">G05</class-ref>). The classification scheme is intended to enable things of a similar nature (as indicated above) to be classified together, and it is therefore particularly necessary for the real nature of any invention to be decided before it can be properly classified.</note-paragraph></note></notes-and-warnings>

In this primary sense, it means finding a numerical expression of the value of a variable in relation to a unit or datum or to another variable of the same nature, e.g. expressing a length in terms of another length as in measuring a length with a scale; the value may be obtained directly (as just suggested) or by measuring some other variable of which the value can be related to the value of the required variable, as in measuring a change in temperature by measuring a resultant change in the length of a column of mercury. However, since the same device or instrument may, instead of giving an immediate indication, be used to produce a record or to initiate a signal to produce an indication or control effect, or may be used in combination with other devices or instruments to give a conjoint result from measurement of two or more variables of the same or different kinds, it is necessary to interpret &quot;measuring&quot; as including also any operation that would make it possible to obtain such a numerical expression by the additional use of some way of converting a value into figures. Thus the expression in figures may be actually made by a digital presentation or by reading a scale, or an indication of it may be given without the use of figures, e.g. by some perceptible feature (variable) of the entity (e.g. object, substance, beam of light) of which the variable being measured is a property or condition or by an analogue of such a feature (e.g. the corresponding position of a member without any scale, a corresponding voltage generated in some way). In many cases there is no such value indication but only an indication of difference or equality in relation to a standard or datum (of which the value may or may not be known in figures); the standard or datum may be the value of another variable of the same nature but of a different entity (e.g. a standard measure) or of the same entity at a different time. <subnote><note-paragraph>In its simplest form, measurement may give merely an indication of presence or absence of a certain condition or quality, e.g. movement (in any direction or in a particular direction), or whether a variable exceeds a predetermined value.</note-paragraph></subnote></note-paragraph></subnote></note-paragraph><note-paragraph>Attention is drawn to the Notes following the titles of class <class-ref scheme="cpc">B81</class-ref> and subclass <class-ref scheme="cpc">B81B</class-ref> relating to &quot;microstructural devices&quot; and &quot;microstructural systems&quot; and the Notes following the title of subclass <class-ref scheme="cpc">B82B</class-ref> relating to &quot;nanostructures&quot;.</note-paragraph><note-paragraph>Attention is drawn to the Notes following the title of section <class-ref scheme="cpc">G</class-ref>, especially as regards the definition of the term &quot;variable&quot;.</note-paragraph><note-paragraph>In many measuring arrangements, a first variable to be measured is transformed into a second, or further, variables.
