Note(s)

  1. This subclass covers also means for identifying or incapacitating burglars or the like.
  2. This subclass does not cover:
    • the mere provision of an audible or visible signalling device on measuring or switching apparatus;
    • alarm arrangements for indicating that a specific variable has exceeded, or fallen below, a predetermined value, which are covered by the relevant subclasses of class G01 for the measurement of that variable.
    • alarms for specific processes or types of machines or apparatus, which are covered by the relevant subclasses for the processes, machines, or apparatus.
  3. In this subclass, the following term is used with the meaning indicated:
    • "arrangements" may cover also devices peculiar thereto.

 G08C
TRANSMISSION SYSTEMS FOR MEASURED VALUES, CONTROL OR SIMILAR SIGNALS (fluid pressure transmission systems F15B; sensing members for specific physical variables, see the relevant subclasses, e.g. of G01, of H01; indicators or recorders, see the relevant subclasses, e.g. G01D, G09F; mechanical means for transferring the output of a sensing member into a different variable G01D 5/00; self-balancing bridges G01R; position control in general G05D 3/00; mechanical control systems G05G; systems for transmitting "on/off" signals only, systems for transmitting alarm conditions G08B; order telegraph systems G08B 9/00; generating electric pulses H03K; coding, decoding or code conversion, in general H03M; radio or line transmission systems in general H04B; transmission of digital information H04L; selective calling from one station to another H04Q 9/00)
