Abstract: According to examples there may be provided a method for classifying a capnogram, the method comprising: obtaining a breath waveform from a capnogram determining one or more transition points of the breath waveform, wherein the transition points comprise: a delta transition point between an expiratory baseline and an expiratory upstroke, a gamma transition point between an inspiratory downstroke and an inspiratory baseline, and an alpha transition point between the expiratory upstroke and an expiratory plateau; extracting features of the breath waveform using the transition points; and applying a trained machine learning model to the extracted features, wherein the trained machine learning model is configured to output a classification of the capnogram from the features.

Abstract: The present invention comprises a composition and methods for treating eye conditions using a composition having a therapeutically effective amount of a progestagen, or a therapeutically effective amount of a progestagen with a testosterone; and pharmaceutically acceptable carrier, wherein the composition is applied to the palpebral part of the eye and/or ocular surface.

Abstract: A sound absorption laminate comprises a porous insulation substrate, such as, a glass, polymeric or natural fiber blanket or a foamed polymeric resin sheet and a facing sheet with a high air flow resistance. The facing sheet is superimposed upon a surface of the porous insulation substrate to augment the acoustical properties of the substrate. With the facing sheet the air flow resistance of the laminate is greater than the air flow resistance of the substrate and the laminate exhibits a higher sound absorption coefficient than the sound absorption coefficient of the substrate. Thus, the laminate exhibits better sound absorption properties than the substrate and is suitable for sound absorption applications for which the substrate alone would not be suitable.

Abstract: An embossing plate having a geometric shape or decorative pattern projecting on its face is used with a printed sublimation transfer paper to impress the pattern in the fabric surface of a fabric-covered substrate.

Abstract: A method of forming a fabric covered end on a wallboard spline structure is disclosed herein. A fixture is provided with a series of recesses to position the fabric and the spline in a desired relationship. An adhesive is provided on a portion of the vertical web of the spline and the inserting of the fabric and the spline into the fixture positions the fabric on the desired portion of the spline.

Abstract: A fabric backing is provided with a plurality of parallel yarns which are adhesively bound to one surface of the fabric backing. The resultant product is then needled with conventional needling apparatus to pierce both the fabric backing and the yarns to provide a plurality of apertures in the fabric backing and the yarn whereby the drape of the fabric is increased and the yarn design is softened.

Abstract: A base structure of a fibrous material has on one face thereof a plurality of acoustical perforations. Positioned over this perforated face is a vinyl layer having a plurality of apertures therein, the apertures of the vinyl being in number much greater than the number of perforations in the base structure. The apertures in the vinyl sheet not all being in alignment with the perforations of the base structure, but the perforations of the base structure having a substantial number thereof in alignment with the apertures in the vinyl structure whereby an acoustical sound absorbing structure is formed.

Abstract: The invention is directed to a wallboard structure which is first composed of a base sheet having a dense upper surface region. Over the dense surface region there is placed a vinyl sheet. Perforations are placed through the vinyl sheet and through the dense surface region and partly into the base region so there is formed an acoustical vinyl faced wallboard.

Abstract: An accessible-demountable support system for kerfed-edge wall paneling and reversible clip means used therein. The system includes vertical splines or runners each having a central web portion with pairs of front and rear flanges extending outwardly in opposite directions at right angles to the web. The front pair of flanges is adapted to be engaged in kerfs in opposing edges of wall panels. One of the rear flanges is adapted to be demountably secured to wall-mounted horizontal support members by reversible resilient clip means. The configuration of the clips is such that when one portion thereof is removably but rigidly affixed to the rear flange of a vertical spline, another portion may be hooked over an upstanding flange on a horizontal support member.

Abstract: The invention herein is directed to a method of providing a ceiling board with a fabric facing. The fabric facing is molded to the irregular shape of the ceiling board so that there is no wrinkling or gathering of the fabric as it is shaped to the configuration of the ceiling board. The lack of wrinkling and gathering is secured without the use of a laborious hand-cutting operation.
