A device of the present disclosure has a board reception plate coupled on a first side to a first side plate and coupled on a second side to a second side plate, and the board reception plate is adapted for supporting a board. The apparatus further has a first spring-loaded sliding bar coupled to the first side plate that has a first channel for receiving a first edge of the board and a second spring-loaded sliding bar coupled to the second side plate that has a second channel for receiving a second edge of the board.

A digital video ramp assembly incorporates process-formed structural LED tiles with modular components that join in a system of scalable structural LED tiles forming a complete LED display structure with integrated LED embedded tiles with interlocking and inter-trans-positioning features sometimes requiring additional structural framing.

A grip pack for providing a slip-resistant, water-resistant, and antibacterial surface to a piece of sporting equipment including at least three substrates printed with images. The images are printed with ultraviolet curable ink and the substrates are non-silicone. Each substrate includes a top printable layer, a middle adhesive layer, and a bottom removable layer. The top printable layer is printed with an image. The bottom removable layer is removable from each substrate printed with an image to expose the middle adhesive layer. The middle adhesive layer is configured to adhere the top printable layer to a surface of the piece of sporting equipment. Each substrate printed with an image and each image printed with ultraviolet curable ink is smoothed flat to conform to the shape of the piece of sporting equipment and provide a smooth protective layer with the slip-resistant, water-resistant, and antibacterial surface.

A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information.

A recreational sports board includes an engraved upper surface providing an attractive detailed image having recessed portions with sufficient depth so as to also provide a suitable grip surface for the rider's feet. A depth of the recessed portions may vary across the board from one location to another location relative to the top side of the board.

A front wheel unit includes a front wheel support portion, which rotationally supports a front wheel, and a front wheel seat, which supports the front wheel support portion such that the front wheel support portion is rotatable at least about the front axis. A rear wheel unit includes a rear wheel support portion, which rotationally supports a rear wheel, and a rear wheel seat, which supports the rear wheel support portion such that the rear wheel support portion is rotatable at least about the rear axis. The front wheel unit and the rear wheel unit are configured such that, when the board portion is tilted in a width direction, the amount of rotation of the rear wheel support portion about the rear axle is greater than the amount of rotation of the front wheel support portion about the front axis.
