Abstract: An apparatus and method are provided for sealing a light imaging array and scintillator of an imaging device which prevents light or moisture from entering the sealed cavity while controlling the lateral expansion of the epoxy material during construction. The seal is formed by dispensing a bead of epoxy around substantially the entire perimeter of the active imaging array and scintillator, leaving a slight gap therein. A cover plate is then placed over the scintillator and imaging array to protect against light or moisture entering the sealed cavity from the side of the substrate that is sealed. As the cover plate is attached, it compresses the epoxy. During compression, pressure builds within the sealed cavity. However, the pressure is allowed to escape through the gap in the epoxy bead. The pressure release lowers the outward force against the epoxy bead, which in turn limits the lateral expansion of the epoxy.

Abstract: A structure for frames for bicycles, wheelchairs, and other vehicles, as well as components thereof and other devices requiring a strong, lightweight frame shell. The preferred frame structure is constructed from plastic molded partial shells that are assembled into shells (such as tubing) that comprises the frame. The partial shells have protrusions and receptacles on the joining faces of their skins that are used to join the partial shells together to form the assembled shell. This results in a lightweight, durable and aesthetically pleasing frame. In an alternative embodiment, the partial shells have protrusions and receptacles within their interiors for additional strength. Additional attachment mechanisms such as screws, bolts, nails, clips or rivets may be used for reinforcement of the partial shells. A method for manufacturing the frame is also disclosed.

Abstract: A method for manufacturing a fiber-reinforce plastic bicycle handlebar by an injection molding process. The resulting handlebar approximates the exterior appearance, configuration and attachment means of traditional prior art handle bars for all terrain bicycles or mountain bikes, while providing a handlebar that is light weight, strong, durable, shock absorbing and cost efficient to manufacture. A manufacturing method for manufacturing the handlebar includes injection of thermoplastic material into a gap located between a core and cavity.

Abstract: A hollow shell frame for bicycles and other human powered vehicles is disclosed. The frame is constructed from plastic molded partial shells that are assembled into tubing that comprises the frame. The partial shells have protrusions and receptacles joining faces of their skins that are used to join the shells together to form the tube. This results in a lightweight, durable and aesthetically pleasing frame. In an alternative embodiment, the partial shells have protrusions and receptacles within their interiors for additional strength. Additional fasteners such as screws, bolts or rivets may be used for reinforcement of the partial shells. A method for manufacturing the frame is also disclosed.
