 G08B
SIGNALLING OR CALLING ARRANGEMENTS; ALARM ARRANGEMENTS (signalling arrangements on vehicles B60Q, B62D 41/00; railway signalling systems or devices B61L; on cycles B62J 3/00, B62J 5/00; signalling or alarm devices in mines E21F 17/18; lamps and shutters therefor F21; sensitive measuring elements, see the appropriate sub-classes of G01; digital signal transmission system G08C; traffic control systems G08G; visual indicating means G09; sound-producing devices G10, H04R; radio or near-field calling-systems H04B; arrangements for selective calling from one station to another H04Q 9/00)
 G08B

Note(s)

  1. The term "arrangements" may cover also devices peculiar thereto.
  2. The mere provision of an audible or visible signalling device on measuring or switching apparatus is not included.
  3. This sub-class includes also means for identifying or incapacitating burglars or the like.
  4. Alarm arrangements for indicating that a specific variable has exceeded, or fallen below, a predetermined value are classified in the relevant sub-classes of class G01 for the measurement of that variable.
  5. Alarms for specific processes or types of machines or apparatus are classified in the relevant sub-classes for the processes, machines, or apparatus.

 G08C
SIGNAL TRANSMISSION SYSTEMS (hydraulic transmission systems F15B; transducers for specific physical variables, see the relevant sub-classes, e.g. of G01, of H01; indicators or recorders, see the relevant sub-classes, e.g. G01D, G09F; arrangements for transmission of measured values G01D 5/00; self-balancing bridges G01R; mechanical control systems G05G; systems for transmitting "on/off" signals only, systems for transmitting alarm conditions G08B; non-electric order telegraph systems G08B 9/00; generating, coding or decoding electric pulses H03K; radio or line transmission systems in general H04B; telegraph systems H04L; selective calling from one station to another H04Q 9/00)
 G08C

Note(s)

This sub-class deals only with systems for transmitting values of a variable, in which the parameter used for the transmission differs from that of the variable


 G08G
TRAFFIC CONTROL SYSTEMS (road engineering aspects E01F 9/00; mounting of detectors in or on roads E01F 11/00)
 G08G

Note(s)

This sub-class includes:

  1. identification of traffic offenders;
  2. indication of the position of scheduled vehicles;
  3. indication of free spaces in parking areas.
