Abstract: A method is provided for analyzing a repaired composite structure composed of a plurality of original plies and additional repair plies at an area of repair. The method includes performing a finite element analysis of a finite element model of the repaired composite structure, the finite element analysis being performed to determine in-situ strains at midplanes of the plurality of original plies and the additional repair plies. The method includes determining in-situ strains at top and bottom surfaces of the plurality of original plies and the additional repair plies from the midplane in-situ strains. The method includes determining a margin of safety for the repaired composite structure from in-situ strain data selected from the midplane in-situ strains and surface in-situ strains. And the method includes outputting the margin of safety from which to, or an indication to, accept or reject the repaired composite structure based on the margin of safety.

Abstract: A method of superplastic forming of titanium packs and an associated assembly is provided. The titanium packs can include sheets having different granular structures so that the different sheets are adapted to superplastically form at different temperatures. One or more of the sheets can be formed at a temperature that is below the superplastic forming temperature of another sheet in the pack. In some cases, the occurrence of markoff can be reduced or eliminated.

Abstract: Illuminating light of selected wavelengths in the visible or infrared range is projected through the pupil of the eye onto the fundus, and the light reflected back and out through the pupil is detected and analyzed, preferably using the area of the optic disk for analyzing the retinal vessels overlying the optic disk. Specific wavelengths of illuminating light may be chosen for each blood component to be analyzed depending on the spectral characteristics of the substance being analyzed. The reflected image from the retina may be used to measure non-photoreactive blood components such as hemoglobin, and photoreactive components such as bilirubin. For the measurement of photoreactive components, images may be taken before and after, or during, illumination of the eye with light at wavelengths which will affect the photoreactive analyte, enabling measurements of the concentration of the analyte.

Abstract: A disposable protective sleeve used for covering laryngoscopes has a sheath and a shield integrally formed of a flexible material. The sheath defines a hollow cavity adapted to enclose a laryngoscope blade. The shield is attached to the sheath and is suited to cover a portion of the laryngoscope handle. The disposable sleeve is molded of a flexible plastic in a size and shape to conform to a particular size and shape of laryngoscope blade. After use, the sleeve is disposed of and the laryngoscope is covered with a new sleeve before being used again.
