Abstract

The microprocessor is used to control the formation of a code from an inductive proximiting detector. The code may be preselected and is supplied from a code generator. Such a system is used where a geographical position is coded or in safety applications. The inductive proximity detector contains an induction coil and a concentric coil which generates a high energy electromagnetic field close to the detector face (20). A static receiver (2) contains a coil (1) tuned to receive the electromagnetic energy from a detector coil (12). These signals are converted (3, 8) and a code generator (7) and static switch operate a series resonant circuit (6, 2) which does or does not absorb the field energy from the induction coil (13) at the code rate. The code generator (23) comprises a sampler controlled by a microprocessor (25) which reinstates the code at the detector output (22) for series transmission on a line (24).
