Abstract: A sun shade assembly includes a first visor structured to have a front side and a back side. The first visor is movably coupled to a vehicle. The first visor is positionable in front of the driver of the vehicle the first visor may provide shade for the driver. A second visor is structured to have a forward side and a rearward side. The second visor is movably coupled to the first visor. The second visor is positionable beside the driver of the vehicle. The second visor may provide shade for the driver. A window is movably coupled to the first visor. The window is positionable in a stored position so the window is concealed within the first visor. The window is positionable in a deployed position so the window extends outwardly from the first visor. The window may provide additional shade for the driver.

Abstract: Conventional first and second Schuler tuned inertial platforms, that are physically displaced from each other by a predetermined distance, are employed in an inertial system to reduce navigation errors caused by the uncertainty in the earth's gravitational field. In addition to the two Schuler tuned platforms, a conventional velocity measuring instrument is employed to provide damping to the inertial system. The invention takes advantage of the fact that for a pair of ideal platforms if the relative velocity between them as displaced sensors can be measured with moderate accuracy then performance rivaling that obtainable with a gradiometer aided inertial platform can be achieved.
