Abstract: A load feedback assembly includes a load receiving portion moveably secured within a main body, a sensor device selectively engageable by the load receiving portion, and a biasing device disposed between the load receiving portion and the sensor device. The biasing device has a biasing force that is configured to urge the load receiving portion away from the sensor device, and the biasing force is overcome when a load on the load receiving portion exceeds a predetermined weight threshold.

Abstract: A multi-configuration apparatus includes a first frame assembly positionable in a first plane and wheels secured thereto such that it is moveable along a surface, a second frame assembly moveably secured to the first frame assembly, and a third frame assembly detachably secured to the second frame assembly. The second frame assembly is moveable between at least a first configuration to move the third frame assembly into a substantially coplanar relationship with the first plane, and a second configuration to move the third frame assembly in a raised configuration relative to the first frame assembly and in a second plane that is substantially parallel to the first plane. The apparatus further includes a support secured to the third frame assembly and wheels such that the third frame assembly is moveable along a surface when the third frame assembly is detached from the second frame assembly.
