Abstract : The patent describes an analog computer for calculating and displaying in digital form the speed and direction of true wind for a ship. Ship's speed and course and wind speed and direction are provided as inputs to a computer which calculates true wind speed by vectorially subtracting ship's velocity from wind speed. The subtraction is accomplished by electronic differential amplifiers which provide true wind speed in cartesian coordinate form. These Cartesian coordinates are converted into polar coordinates which are then fed into an analog to digital converter so that a readout can be displayed in digital form.
