Speed and direction indicator for ships
First Claim
1. A speed and direction indicator for a ship having first and second drive means, each for steering and propelling said ship, comprisingfirst steering response means operatively connected to said first drive means for producing signals indicative of the steering effect of said first drive means on said ship,second steering response means operatively connected to said second drive means for producing signals indicative of the steering effect of said second drive means on said ship,first propulsion response means operatively connected to said first drive means for producing signals indicative of the propelling effect of said first drive means on said ship,second propulsion response means operatively connected to said second drive means for producing signals indicative of the propelling effect of said second drive means on said ship,computer means operatively connected to said first and second steering response means and to said first and second propulsion response means for computing the resultant steering and propulsion effect of said first and second drive means on said ship, andoptical display means operatively connected to said computer means for providing a graphic display of the effect of said first and second drive means on the steering and propulsion of said ship.

Abstract
A speed and direction indicator for ships having at least one rudder propeller, or pump jet, and preferably several such devices for determining the direction of the ship and its speed in the selected direction. An optical display is provided in the area occupied by the ship operator, on which display are shown the angle which is formed between the direction of force and a reference direction, and the strength of the thrust, independently of the operating state of the rudder propeller(s) or the pump jet(s).
