Abstract: A sole system for an article of footwear can include a sole member and a protruding member assembly. The sole member includes outwardly and inwardly facing surfaces and a plurality of spaced apart apertures extending though the sole member. The protruding member assembly includes a plurality of protruding members, where each protruding member is vertically movable within a corresponding aperture of the plurality of apertures of the sole member. A first set of protruding members is arranged in a first region of the sole member, a second set of protruding members is arranged in a second region of the sole member, and a spacing between adjacent protruding members of the first set is smaller than a spacing between adjacent protruding members of the second set.

Abstract: A sole system for an article of footwear can include a sole member and a protruding member assembly. The sole member includes outwardly and inwardly facing surfaces, and a plurality of spaced apart first apertures extending through the sole member. The protruding member assembly includes a plurality of first protruding members, each being vertically movable within a corresponding first aperture of the sole member. Each first protruding member has a first end portion, a second end portion, and an intermediate portion where an inwardly facing surface of the first end portion is flat and oriented to conform to a shape of a foot of a wearer of the article of footwear.

Abstract: A sole system for an article of footwear can include a sole member and a protruding member assembly. The sole member includes outwardly and inwardly facing surfaces, a plurality of spaced apart first apertures extending though the sole member, and a plurality of first protruding members extending outward from and fixed to a base surface of the outwardly facing surface. The protruding member assembly includes a plurality of second protruding members that are interconnected by connecting portions, where the connecting portions are received on the inwardly facing surface of the sole member, and where each second protruding member is vertically movable within a corresponding first aperture of the sole member.

Abstract: The present disclosure relates to an off-road vehicle having different features such as a frame having a frame structure, an engine assembly, an exhaust assembly, an engine mount assembly, a suspension assembly, a plurality of wheels, a hitch assembly, and other associated components. Embodiments of the present disclosure also describe a removable frame member facilitating the installation of the engine assembly from a seating area into a rearward portion of the vehicle. The off-road vehicle may further include an engine air intake assembly, an engine cooling assembly, a continuously variable transmission (CVT) cooling assembly, a vehicle cabin cooling assembly, a CVT housing assembly, a door assembly, a dashboard assembly, and other components.

Abstract: A piezoelectric harvesting system using repulsion force, according to one embodiment of the present invention, comprises: a piezoelectric body comprising a piezoelectric material; a fixed portion to at least one surface of which the piezoelectric body is adhered; a support portion for supporting one side of the fixed portion; and a repulsion force-providing portion for providing repulsion force to the fixed portion, so that the piezoelectric body generates electric energy when the fixed portion is deformed due to application of external force and then recovered. According to one embodiment of the present invention, additional shock is applied to the fixed portion to which the piezoelectric body is adhered when recovering after being deformed, thereby increasing the amount of electric energy generated due to the deformation of the piezoelectric body.
