Abstract: A system and method using a mount assembly for attaching a powertrain to a structural member of a vehicle. The mount assembly includes a first compliant member, a second compliant member, a first fluid chamber, a second fluid chamber, a pressure compliant membrane, electro-magnetorheological switch and a magnetorheological fluid. A fluid conduit interconnects the first fluid chamber with the second fluid chamber to allow a fluid to pass from the first fluid chamber to the second fluid chamber. The pressure compliant membrane seals the aperture in the second fluid chamber. The electro-magnetorheological switch is activated to generate an electric field in the fluid conduit to change the viscosity of the magnetorheological fluid to achieve a first stiffness profile of the mount assembly. The electro-magnetorheological switch is deactivated to remove the electric field in the fluid conduit to change the viscosity of the magnetorheological fluid to achieve a second stiffness profile of the mount assembly.

Abstract: A climbing aid for a ski has a plane base element which is connected on the inner side to a fastener to be detachably fastened to a running surface of the ski and which is connected on the outer side to backwards-slipping prevention elements acting contrary to a direction of travel. A flexible plastic support material forms the base element, and the backwards-slipping prevention elements are integrally formed with the plastic support material. In lateral regions, the base element has backwards-slipping prevention elements with push-off wings positioned obliquely to the direction of travel and, in the central region, has backwards-slipping prevention elements with push-off wings arranged substantially perpendicular to the direction of travel. The push-off wings of the backwards-slipping prevention elements of a first type are of lesser length and/or of lesser height than the push-off wings of the backwards-slipping prevention elements of a second type.

Abstract: A system and method using a mount assembly for attaching a powertrain to a structural member of a vehicle. The mount assembly includes a first compliant member, a second compliant member, a first fluid chamber, a second fluid chamber, a third fluid chamber, a pressure compliant membrane, and a valve. A fluid conduit interconnects the first fluid chamber with the second fluid chamber to allow a fluid to pass from the first fluid chamber to the second fluid chamber. The third fluid chamber has an opening in communication with the second fluid chamber and a vent port. The pressure compliant membrane seals the opening between the second fluid chamber and the third fluid chamber. The valve selectively seals the vent port in the third fluid chamber. A first stiffness profile of the mount assembly is selected by actuating the valve to open the vent port. A second stiffness profile of the mount assembly is selected by actuating the valve to close the vent port.
