Abstract: Roof panels and roof panel assemblies, comprising roof panels and ridge beams, assemblies are disclosed for use in building construction. The roof panels and ridge beams comprise components formed of composite materials, and certain aspects of the invention include designs that provide for the absorption of solar heat and the promotion of hot air flow within the roof to heat the interior building or generate electricity, among other attributes.

Abstract: Novel cutting guides and surgical methods for use in knee arthroplasty are described. Embodiments of the inventive cutting guide apparatus include fixed and adjustable cutting guide blocks having a series of slots designed to accommodate a cutting saw. The cutting guides and surgical method are designed to allow for the provision of all desired surgical cuts upon the distal end of the femur, for subsequent implantation of a prosthesis thereto, without having to remove the cutting guide block.

Abstract: Novel building systems, in particular low cost superior strength building assemblies incorporating single or double shear walls, and disaster resistant window attachments are described herein. The inventive building systems are particularly well-suited for adding rooms to existing buildings, such as attached residential room additions, basements, disaster relief housing, and Do-It Yourself (DIY) projects.

Abstract: A novel apparatus and device is described for reconstituting a bone sample with a biological fluid, such as concentrated plasma or saline solutions, for example, prior to surgical implantation into a patient. In particular, the invention comprises, in certain aspects, a container in which a bone sample may be reconstituted with the desired fluid by applying a vacuum within the container, thereby driving the fluid into the bone for complete, or near complete, permeation of the fluid into the interstices of the bone sample prior to surgical implantation.

Abstract: Novel femoral implants for use in hip arthroplasty are described and illustrated. The femoral implant comprise a stem and neck portion, with the neck portion having a novel configuration that provides for improved range in motion for the prosthesis without compromising strength of the implant.
