DEFINITION

Classification: 340/870.01

CONTINUOUSLY VARIABLE INDICATING (E.G., TELEMETERING):

(under the class definition) Subject matter for giving an indication, at a receiving station, which is substantially continuous from a lower value to an upper value, said indication being under the control of a transmitter, said control being exercised over an electric circuit.

(1) Note. The word "continuous", as used in the above definition, refers to the characteristic under which the valve indicated is quantitative rather than qualitative; thus, for example, a system which nominally indicates a temperature in degrees is classified in this and indented subclasses, but a system which indicates temperature merely by designations such as "hot", "medium", and "cold" is not classified here, but in Class 340, subclass 584. Thus, the intelligence or variable indicated is basically an analog, human sensible value input.

(2) Note. The quantity whose value is telemetered may be measured in a testing operation. This subclass, however, takes only those telemetering systems not limited to testing or which are not provided for in the testing classes. See the subclasses referred to below under "SEARCH CLASS".

(3) Note. This subclass includes, in addition to automatically responsive telemetering systems, those in which the quantity to be telemetered is determined by a manual operation; for example, the desired as well as the actual temperature of an auditorium may be telemetered from the auditorium to the heat control room.

(4) Note. This is the generic subclass for electrical telemetry signaling means useful in transmitting a sensed

quantity and not provided for in other classes.

(5) Note. For the purposes of this subclass definition, a telemetry system provides the equipment necessary to sense such conditions as pressure and temperature and to transmit their electrical equivalents via a particular channel or means, but often via a radio link to another location for display and/or recording.

(6) Note. Telemetry, also called telemetering or remote metering, is measurement which through intermediate means, can be interpreted at a distance from a primary detector. A receiving instrument converts the transmitted electrical signals into units of data which can then be translated by data reduction into appropriate units. (7) Note. Class 73 takes telemetric signaling means in combination with a particular measuring means of the type provided for in Class 73.

(8) Note. Class 324 takes telemetric signaling means in combination with a particular measuring means of the type provided for in Class 324.

(9) Note. Class 356 takes telemetric signaling means in combination with a particular measuring means of the type provided for in Class 356.

(10) Note. Class 374 takes a telemetric signaling arrangement in combination with a structurally detailed measuring arrangement provided for by Class 374.
