Abstract

An interlock system (10) comprising: a first part (12) including a transmitter (30); and a second part (14) including a receiver (50); whereby the first part (12) is configured to be held in a position adjacent the second part (14), and wherein the transmitter (30) and receiver (50) are configured to operate using an electromagnetic signal at a frequency substantially between about 1k Hz and about 30k Hz and are disposed on opposing sides of a barrier (20), such that a signal from the transmitter (30) for identifying the first part (12) is receivable by the receiver (50), through the barrier (20).
