One aspect of this disclosure is a sliding apparatus. In some aspects, the sliding apparatus may comprise an elongated body containing magnets. The elongated body may comprise a toe end, a tail end, a top surface, and a slide surface. In one aspect, the magnets may be located between the toe and tail ends of the elongated body, spaced apart from one another in the elongated body, and polarized to define top poles oriented toward the top surface of the elongated body and bottom poles oriented toward the slide surface of the elongated body. For example, the magnets may be arranged so the bottom poles have alternating polarities in a direction relative to the elongated body. Related apparatus and systems also are disclosed.

A sports equipment article comprises a thermoplastic poly(carbonate-siloxane) elastomer.

The present invention generally relates to a cover for sports equipment, such as for skis, snowboards, surfboards, skateboards and the like. In one embodiment, the cover is formed in a similar shape to the equipment it is meant to cover, and large enough to cover at least one flat side and the edges of the equipment, while optionally leaving some portion of the equipment open to the air. The cover is made of a either a combination of fabrics, or a combination of faces of fabric, which allow for moisture to be wicked away from the sports equipment, and which provide protection for the equipment from rust and/or other damage.

A system, method and apparatus for a digitally Controlled Variable Stiffness item of athletic equipment, such as a Ski, Snowboard, and Boots. A core of thermally responsive metal alloy, such as Nitinol is disposed within the athletic equipment. A thermal control module and controller permit the athlete to program the athletic equipment to a desired stiffness parameter. The controller may include an app operable via a mobile computing device in communication with the thermal control module.

A method of manufacturing a snow sliding device includes forming a core by forming a core body including an outer surface including an upper surface, a lower surface, and a first thickness, and shaping the core body to include a second thickness; providing a plurality of elements, including a base with a sliding surface, and a top surface; incorporating in at least one of the core and the plurality of elements a first material, the first material exhibiting a shear rate-dependent shear resistance; and laminating the plurality of elements to the core.

A snow and water sport sliding device with a pneumatic core and method of manufacturing the device. The device includes a top layer comprising a front tip, a middle segment with a binding plate, and a back segment with an adjustable air valve. Top layer may also include a blade spring system. The device also includes a main core component layer under the top layer that comprises of a hollow air chamber, and a base layer. Base layer may include embedded metal edge.
