A water propulsion electric powered water recreation surf board with an integrated water propulsion jet to provide additional thrust for maneuvers and different selectable thrust levels as needed during the maneuver. The water propulsion electric powered water recreation surf board includes a body having an upper surface and bottom surface and a water propulsion system integrated into the body including a water inlet on the bottom surface, and a water propulsion nozzle and propeller on the upper surface. An electric motor connects to rotate propeller for drawing water into the propulsion system and expels a pressurized column of water through the water propulsion nozzle. A removable rechargeable battery is connected with the electric motor and a controller with a user control pad on the top surface of the body to allow the user to control the operation of the water propulsion system.

A self-propelled personal flotation apparatus provides a motorized flotation board which includes internal water propulsion equipment and associated push-button controls. In use, a user straps the apparatus onto their chest area, enters a body of water such as a lake, a pond, or a pool, and is propelled across the water surface.

A jewelry display includes a ferromagnetic planar substrate having a front surface opposite a back surface. A bracket is configured to be attached to a wall, the bracket comprising at least one bracket magnet which is a permanent magnet. The back surface of the ferromagnetic planar substrate is configured to removably attach to the bracket due to the magnetic force of the at least one bracket magnet. A plurality of jewelry fixtures are configured to be removably attached to the front surface of the ferromagnetic planar substrate. Each jewelry fixture includes at least one permanent fixture magnet and a jewelry holding structure. The at least one permanent fixture magnet of each jewelry fixture is magnetically attracted to the ferromagnetic planar substrate. The at least one bracket magnet may be at least 2, 5, 10 times or more as powerful as the at least one permanent fixture magnet.

An exhaust system for a combustion engine vehicle includes an exhaust pipe extending between an exhaust inlet disposed opposite an exhaust outlet. The exhaust inlet and exhaust outlet are in fluidic communication with one another. The exhaust inlet is configured to receive an exhaust gas produced by an internal combustion engine of the combustion engine vehicle. A second pipe has an air inlet extending from and connected to the exhaust pipe. The second pipe is configured to be in fluidic communication with the exhaust outlet. The air inlet is configured to receive an outside flow of air. The exhaust gas from the combustion engine vehicle and the outside flow of air captured by the air inlet when the combustion engine vehicle is moving forward are configured to be combined and to cooperatively exit out the exhaust outlet.

A kickboard has a non-planar shape and comprises a primary panel with opposite support members laterally outside from the primary panel with a transitional section therebetween. The support members are at a rear longitudinal position and additional support shoulders may extend from a forward end of the primary panel along each lateral side to a respective support member. The rearward end defines an opening with a cavity formed between the primary panel, transitional sections, support shoulders and support members. In use, the kickboard provides substantially improved ergonomics and allows a swimmer to support her elbows on the support members with a portion of her forearms on the support shoulders, with arms in a bent position below the surface of the water. The configuration improves comfort while maintaining a favorable hydrodynamic swimming position and reducing shoulder stress.

A hydrofoil and hydrofoil system for a surfboard is disclosed. The surfboard has a planar hull defined by a top surface, a bottom surface, a nose, a tail, and opposing side rails extending from the nose to the tail and that define a transition from the top surface to the bottom surface. The hydrofoil system includes one or more attachment mechanisms mounted with the planar hull at or proximate to at least one of the opposing side rails of the planar hull, each of the one or more attachment mechanisms comprising an attachment site oriented substantially laterally from the planar hull. The hydrofoil system further includes a hydrofoil configured to attach to the attachment site of one of the one or more attachment mechanisms, the hydrofoil further being configured to extend substantially laterally from the planar hull at or proximate to the at least one of the opposing side rails of the planar hull.
