  • Patent number: 10696316
    Abstract: The stair-climbing stroller is a baby stroller with retractable front and rear wheels for use on flat travel surfaces and a pair of tracks for use on inclined travel surfaces including, but not limited to, staircases. The front wheels are coupled to a pivoting front wheel support shaft and the rear wheels are coupled to a pivoting rear wheel support shaft. A wheel retract motor located on the underside of the stroller may cause a retraction drive shaft to pivot the front and rear wheel support shafts, retracting the wheels. When the front and rear wheels retract, the stroller may be lowered such that the left and right track rest on the ground. Left and right track motors may then be used to drive the stroller up an inclined travel surface using the tracks.

    Abstract: A machine employing controllable mounts and a method for controlling such mounts based on operator input are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so is the stiffness and damping of the controllable mount. Depending on various factors, the operator may want a particular level of feedback. For example, when fine grading, the operator may want to feel every vibration and thus the controllable mounts should be as stiff as possible. The present disclosure therefore provides the operator with the ability to select the desired level of feedback.
