Abstract:

This patent discloses an underwater acoustic control system for use in a subsurface unit receiving coded signals. A hydrophone receives the signal and enables an electronics package to supply a control pulse which could activate a switch or fire a squib. A timer is included in the package to provide a delayed turn-on of the receiver circuit for as long a period as desired.
