• the transmitter 64 of each communication device 12A, 12B is a transmitter capable of emitting a frequency sound signal included in the audio band [20 Hz - 16 kHz].
• the transmitter is capable of transmitting a signal with a frequency below 20 Hz or a signal with a frequency greater than 16 kHz.
• This makes it possible, for example, to use as the transmitter 64 the loudspeaker of any conventional telephone 12A, 12B and as a signal sensor 44 an audio sensor.
• This further allows a given instruction 18 to automatically recognize, when receiving the signal 56 comprising a numeric key coded CNC or non-coded CN, the communication device 12A, 12B emitting the signal.
• the only difference between the object distribution system according to the embodiment shown in Figure 4 and the object distribution system according to the first embodiment illustrated in Figures 1 to 3 is that the distributor, as the recipient, instead of approaching a single control module to issue a CNC-encoded digital key, approaches the instruction 18 concerned which contains one of the control modules.
