Patent ID: 8091420

Claim:
An apparatus for indicating wind direction and speed, comprising: a. a generally circular base member mounted for rotation in a generally horizontal plane; b. a vertical rudder secured to the base member, adjacent to one point on the perimeter, wherein the mounting location of the rudder and a point at the opposite end of the circular base define a front-rear axis of the circular base, with the rudder mounted at the rear, the axis bisecting the circular base into a left side and a right side; c. a first plurality of fixed light sources forming a predetermined array of color combinations, mounted on the periphery of the base member, with the color combinations arranged in relation to the rudder, whereby the force of the wind upon the rudder causes the base member to rotate to assume an orientation facing into the wind and thereby to position the light sources to provide a visual indicia of wind direction, wherein the first plurality of light sources includes a first and a second subset of light sources, the first subset displaying a first color being mounted on the perimeter of the left half of the circular base, and the second subset displaying a second color being mounted on the perimeter of the right half of the circular base; and d. an anemometer device including: a lever having a pivot end and a distal end, the pivot end rotatably attached to the base member for movement of the distal end in the vertical plane; an airfoil positioned on the distal end, and moveable in the vertical plane in response to the changes in wind pressure on the airfoil; and a second plurality of light sources positioned in a vertical array above the base member and in electromechanical communication with the position of the airfoil, wherein a predetermined set of light sources are illuminated in response to the position of the airfoil.
