Abstract

PURPOSE:To make it possible to find victims of a distress at sea securely by making a report by an information unit when a distress signal is received. CONSTITUTION:A distress signal, once applied to input terminal 1, is filtered by filter 2 and then applied to gate signal generator 3 and gate circuit 4. Gate signal generator 3 releases gate circuit 4 for a certain time and counting circuit 5 counts the number of pulses of the distress signal. When the count value of counting circuit 5 exceeds the reference value of reference pulse generator 7, comparing circuit 6 generates an output, and consequently switch circuit 8 is driven to put timer 9 into operation, activating display unit 10 for a certain time.
