Abstract: In accordance with the teachings of the present invention, a helmet having interior ventilation channels is provided. In a particular embodiment, the helmet includes at least one protective layer configured to cover at least a portion of a user's head and a plurality of pads coupled to the protective layer, the pads defining a network of interconnected ventilation channels between the pads, the ventilation channels substantially covering an interior of the protective layer and allowing air circulation between the protective layer and the user's head when the helmet is worn by the user.

Abstract: A modular tile and modular tile system is disclosed. The modular tile includes a base structure having a generally horizontal portion. Floor support members are positioned on a bottom surface of the generally horizontal portion. Upper column members extend above the horizontal portion of the modular tile. A cover is supported by the upper column members a distance above the horizontal portion thereby creating a chamber between the horizontal portion and the cover. The chamber is adapted to receive cabling therein.

Abstract: An elongate snowboard having a body which is characterized by a central region which, in transverse cross section is convex in relation to the way it faces a snow surface, first and second end regions each joining with opposite ends of the elongate central region and each of which, in transverse cross section is concave in relation to the way that it faces a snow surface, with the central and end regions collectively being characterized, as one looks at either broad face of the snowboard, by bilateral symmetry relative to both the central longitudinal axis of the board and to the central transverse axis thereof.

Abstract: A combined chair and table structure including a seat having first and second front corners, a first table mount extending upwardly from the first front corner, and a second table mount extending upwardly from the second corner; a first table having a planar, horizontal upper work surface and a planar, horizontal bottom surface; a first mounting mechanism including a linear track attached to the first table bottom surface, and a mount rotatable in the first table mount, the track being slidable in relation to the mount; and a second table rotatably supported on the second table mount.

Abstract: A support is shown for an image display system that is to be worn on a user's head. The image display system includes an image generating module with at least one optical element into which a user looks to view a generated image and an electronics module, both of these modules being removably mountable on the support. The support includes a head hugging member having a front portion, a pair of side portions, a top portion and a back portion integrally formed from a material with multidirectional elasticity so that the side, top and back portions conform to and hug the user's head. The support also includes a rigid bill secured to the front portion of the head hugging member so that it extends outwardly from a user's forehead for providing a rigid support onto which the image generating module is mounted.

Abstract: A unitary, monocoque, injection-molded skateboard (and method of making the same) which is characterized by an elongate composite body with a specific gravity in the range of about 0.75 to about 0.8, and including a foamed structural plastic mass having a distributed differentiated density, and contained within that mass, plural, elongate strands of reinforcing carbon fibre material.

Abstract: A wrist rest is disclosed for use with a keyboard. The wrist rest includes a bladder for holding a fluid, a pump operatively connected to the bladder for selectively filling the bladder with fluid and a valve for selectively releasing fluid from the bladder. The bladder preferably includes two elongate lobes interconnected by an isthmus. The lobes are shaped so that the perimeter of a horizontal cross-section through one of the elongate lobes is substantially elliptical in shape.

Abstract: Disclosed is a cushion for supporting the lumbar area of the back of a person while seated in a chair. The cushion is suitable for use with different types of chairs and is comprised of an elongated strip of flexible material that drapes over the chair back and has a weight on one end thereof to allow easy adjustment of the cushion and a pad of foamed cushion material at the other end. The pad of foamed cushion material is adapted to fit between the chair back and the lumbar area of the back of the seated person and is preferably made of a heat sensitive plastic foam that will mold itself to conform to the shape of the lumbar area of the user's back from the body heat of the person seated in the chair.

Abstract: A tunable snowboard having a base with perimetric edge tunability so that the controlling edge can be formed to meet the specific needs of the end user. The tunability is provided by a sheet of tunable material that covers some or all of the base. The amount of the base that is covered with tunable material in any one part of the snowboard is selected based on how much adjustment is to be provided in that part. A method for making a snowboard is also disclosed, including providing tunable material in the approximate shape of a snowboard. The tunable material is shaped to cover preferably from 10-percent to 100-percent of the base of the finished snowboard and a deck of structural material is bonded to the tunable material. In addition, the method can include cutting a hole in the tunable material adjacent an end of the snowboard and then extruding a portion of the deck material through the hole, and molding indentations, a step plate pattern and binding mounting plate patterns into the deck.

Abstract: An injection molded, single-piece plastic bicycle frame which includes a generally upright stem, and a cantilever structure joined to and extending from opposite sides of the stem in a gently curving, downwardly facing reverse bend. The material forming the frame has a nonuniform internal structural density which is characterized by higher density adjacent the surface, and by decreasing density progressing toward the core. This material preferably takes the form of a foamed structural plastic material.

Abstract: An integrated adjustable data entry keyboard. A divided keyboard arrangement comprises first key field and second key fields pivotably mounted upon a stationary base. The first and second key fields substantially comprise a keyboard arrangement. A space bar is separately attached to the base and occupies a lower keyboard region centrally disposed between the first and second key fields. The space bar is enlarged so as to remain within the radius of a user's thumb's "strike zone" when a user adjusts the first and second key fields. A synchronizing coupling means may be employed to ensure complimentary movement of the first key field relative to the second key field and thereby relative to the user's hands and wrists, even if only one of the individual key fields is pivoted.
