Abstract: A respiratory mask includes a mask frame, a cushion and a retaining element. The retaining element is embedded within the cushion and is configured to secure the cushion to the mask frame. Forehead pads can be positioned in the mask frame and be adjustable independent of one another and with respect to the mask frame.

Abstract: A dual band spectrometer (40) for imaging one or two spectral bands onto a common image plane. The spectrometer (40) includes an input aperture (42) for receiving scene photons; an entrance slit (46) illuminated by photons from the input aperture (42); a diffraction grating (50) for dispersing the photons into spectral bands, such that at least one of the spectral bands embodies two diffraction orders; a collimator (48) for collimating the photons from the input aperture (42) and directing the photons toward the diffraction grating (50); an image plane (60) receiving the at least one spectral component from the diffraction grating (50); and an order sorting filter device (54) interposed between the diffraction grating (50) and the image plane (60), such that the filter device (54) is operable to pass only one of the two diffraction orders onto the image plane (60).

Abstract: The knee brace of the present invention comprises a pair of elongated articulated assemblies adapted to embrace the interior and exterior surfaces of the knee. Each assembly comprises an upper member, a lower member, and a hinge pivotally interconnecting the upper and lower members. The upper and lower members each include arcuate gear surfaces which intermesh during articulated movement of the members and the hinge. The gear surfaces include annular flanges which reinforce the gear teeth on the gear surfaces.

Abstract: A method is disclosed for preparing a high fiber, low-calorie pasta. A mixture is prepared which may include cereal material, oil seed endosperm cell wall residues, vegetable protein, calcium carbonate, vegetable gum, and water. The mixture may be extruded and/or shaped to form the pasta.
