Zusammenfassung:A central processor 60, via a nodal processor 40, controls polling units 20/I ...20/N each of which transmits repeatedly a series of addresses each address followed by a gap for a response. Living creatures or objects (mobile) to be identified carry respective automatic response means 10. When a means 10 is in range and receives its own address it transmits a response signal to the polling unit. The polling units may be connected in a ring. There may be a single polling unit which moves past response means carried by entombed miners.
