Patent ID: 7089674

Claim:
A measuring device for determining terrain slopes while operating a motorcycle, said measuring device comprising: a housing having a plurality of monolithically formed walls sized and shaped for being removably attached directly to a selected portion of the motorcycle, said housing further having an annular opening formed within selected ones of said walls in such a manner that the opening extends rearwardly from a front one of said walls and terminates anterior to a rear one of said walls; a transparent lens monolithically formed with said housing and directly connected thereto, said lens covering an entire surface area of the opening and spaced forwardly of said rear wall, said lens protruding away from said housing and defining a cavity in fluid communication with the opening; a buoyant member situated within the opening and the cavity, said buoyant member having surface indicia printed thereon for illustrating a plurality of degree-measuring markers defined about an x-axis and a y-axis, said buoyant member having a reference line registered at equilibrium when said housing is aligned with the x-axis and y-axis respectively; and a predetermined quantity of high viscous fluid contained within the opening and the cavity such that the fluid freely flows therebetween and supports said buoyant member at a free and suspended position during operating conditions; wherein said buoyant member includes a weight member connected to a bottom portion thereof and thereby anchors said buoyant member while allowing said buoyant member to freely rotate about one or both of the x-axis and y-axis, the rotation about one of the x-axis and y-axis results from application of a torque to another of the x-axis and y-axis when said buoyant member is spinning so that said measuring device offers considerable opposition depending on an angular momentum of any torque that would change the direction of the axis of spin.
