Abstract: The present invention relates to spacers that are configured to promote fusion. Windows or openings in the sidewalls of the fusion spacers may be provided to allow a physician to view the treated area to confirm that fusion has occurred or to check on the progress of treatment. Fusion spacers of the invention may have two or more pairs of openings or windows that allow viewing of the treated area from different perspectives.

Abstract: An electronic calculator apparatus converts between bushel measures of a selected crop product and weight measures of the selected crop product. The apparatus comprises a microprocessor and a keyboard comprising a numerical portion, a crop product portion, and a conversion portion operative to transmit to the microprocessor respective numerical, crop product, and conversion data inputs selected by a user. The microprocessor is programmed with known arithmetical relationships between bushel measures of selected crop products and corresponding weight measures of the selected crop products and is operative to receive the numerical, crop product, and conversion data inputs and to provide a data output corresponding to a desired conversion between bushel measures and weight measures. A display is coupled to the microprocessor and is operative to display the data inputs and data output to a user.

Abstract: The invention is directed to compositions of mutated binding proteins containing thiol groups for coupling to sensor surfaces, analyte biosensor devices derived there from, and methods of their use as analyte biosensors both in vitro and in vivo.

Abstract: The invention generally concerns a spine stabilization system having one or more flexible elements having an opening or slit. The flexible element may be integrally formed in a rod having ends capable of receiving fasteners. The flexible element may limit rotation, flexion-extension, or lateral bending of the spine. The slit or opening may form helical pattern on the rod, and more than one slit or opening may be provided. The flexible element may be conformable to the natural spinal movement.
