Method for connecting mobile instruments to central equipment, comprises emission of code by instrument when near central station and recording of instrument identification by central equipment

摘要

A mobile instrument emits an identification code (1) including an identifier when it receives a low frequency signal from the central equipment (36). The low frequency signal is sent when the central equipment detects (39) the proximity of a magnet on the mobile instrument. When the identification code is received (42) by the central equipment it is recorded (2) and validated (41). Independent claims are also included for; (1) a mobile instrument, and (2) central equipment.
