Abstract
A device to warn a ship crew of submerged objects in their immediate vicinity, combined with alarm and logging facilities. The device is composed of one or more sonic or ultra sonic transducers placed aboard the ship, with coverage arranged so as to give surrounding 'envelope' to the sides and to the area ahead of the vessel, as well as some predetermined downward looking angle. The transducer or transducers are connected to an electronic distance measuring device that will measure distance to possible obstacles, similar to conventional sonar techniques. The measurements in each direction are compared by an electronic processor against a table of minimum distances, and if the distance falls below the predetermined value for a given direction, an alarm is activated. In addition, all alarms, cancellations of alarms, activation and deactivation of the system are logged automatically with an identification of the operator.
