Abstract:
A personal wind-powered hydrofoil watercraft having a sail supported by a mast coupled to a buoyant body, where the mast is tiltable forward and backward but not side to side, in order to prevent excessive rolling of the buoyant body when it is lifted clear of the water on the hydrofoils. Additionally, the buoyant body may be in the shape of a pontoon, the watercraft may be steerable by a steering mechanism actuated by a human operator's foot or feet, and the front hydrofoil may be associated with a surface tracking means in order to stabilize the altitude of the watercraft.
Abstract:
A scooter device propelled by side to side movement of a user that includes a frame structure through which at least a front wheel is coupled to two direction biased rear wheels. The frame structure may have a foot placement platform that extends laterally between the two rear wheels. The platform may extend over half of the distance between the rear wheels and/or be substantially continuous for that distance. Various platform embodiments and frame structures, including rigid and flexible, are disclosed, among other aspects.

Abstract:
A screen for a trade show or like environment that is lightweight, flexible and compactible. The screen may be patterned to include a plurality of ridges extending from a top to a bottom thereof that serve to reflect projected light into a larger field of view. The screen may be concave about a horizontal axis of otherwise arranged to reflect projected light toward a desired audience. Various releasable, biased mechanisms for attaching a flexible screen member to a disassembleable frame structure are also disclosed.
Abstract:
A motorized hydrofoil water craft that has a substantially horizontally disposed flotation device that may be configured to receive an adult human in a prone, sitting or standing position. The craft includes a hydro foil, a motor, and a steering mechanism. The hydrofoil may have various configurations and be detachable, while the motor may be electric and have an associated battery that is situated underwater in use. The steering mechanism may include a canard and be configured for vertical movement of the canard. Several embodiments are disclosed.
Abstract:
A multi-component drain and/or serving tray apparatus. A perforated drain tray is provided that has an opening which accommodates a drain plug. The drain plug may be configured for draining various sized canned goods. A bottom and/or top housing member may be provided to receive drainage materials or to cover food items, etc. The apparatus in various arrangements may be used for many purposes.
Abstract:
A self-propelled hydrofoil device having front and rear foils, a support structure and a steering mechanism. The device is preferably fabricated with a flexible steering and/or support member that permits the drive foil to move in an appropriate manner through water to propel the device forward. Various embodiments are disclosed.
Abstract:
An exercise device having an elongate, substantially rigid pad. The exercise device also includes a pair of handrollers, each handroller comprising a handgrip supported between a pair of wheels. The device also includes a pair of stretchable tensioning members. Each of the tensioning members interconnects a respective one of the pair of handrollers and the pad.
Abstract:
A reflective projection screen has in a first aspect a plurality of reflective elements. The upper surface of the reflective elements is either coated or textured to interfere with reflection of light from the upper surface to an adjacent reflective element. In a second aspect of the invention, a screen is provided that reflects light in the vertical direction like a plane surface, while reflecting light in the horizontal direction back toward the light source. In a third aspect of the invention, a projection system projects a three-dimensional image.
