Abstract: A protective oral sex face mask is described herein that protects a first wearer and second user during sexual activity. The mask performs as a prophylactic against STDs and other infectious agents. The face mask includes a body portion bounded by a top boundary, a bottom boundary, a first side boundary, and an opposing side boundary. The body portion further includes an interior surface touchable by the first user's tongue, and an exterior surface touchable by a second user. The mask includes a snug tongue pouch maintaining sensory perception of the first wearer while performing oral sex.

Abstract: An incident angle when illumination light from a position detecting device enters a reflecting surface may be large in some cases. In such cases, the retro-reflection rate of a reflecting surface having a prism structure decreases, leading to a cause of erroneous detection. In order to solve this problem, provided is a reflecting plate including a reflecting surface that retro-reflects illumination light emitted from an optical position detecting device towards the position detecting device that includes a light source, the reflecting plate further including: a surface structure in which a concavo-convex pattern having the same triangle shape in cross-section in a width direction of the reflecting plate continuously appears in a longitudinal direction thereof; and a retro-reflecting layer in which reflecting beads are evenly placed on at least one oblique surface of the concavo-convex pattern.

Abstract: In a reversible welt patch pocket according to the present invention, a pocket pouch is formed by a patch pocket and a garment main piece. The top of the patch pocket is unattached to allow access to the contents of the pouch. The garment main piece has a slit attached to a welt for allowing access to the contents of the pouch. Accordingly, the contents of the pocket pouch are accessible regardless of which side of the garment is worn as the outside.

Abstract: A reversible garment is provided with a two-sided pocket comprising a main piece with an access opening, a pocket piece with an access opening that is aligned with the access opening of the main piece, and a lining piece between the main piece and the pocket piece, and having an edge present in the access openings of the main piece and the pocket piece. Stitching around the edge of the pocket piece couples the pocket piece to the lining piece and the main piece. This two-sided has less bulk and more flexibility than the conventional method of attaching mirror patch pockets to either side of a reversible garment.

Abstract: A reversible hat with a visor has pockets with closures. The hat is of the form sometimes referred to as a baseball cap. The crown and front portions of the hat have a single layer of fabric, so that the hat is relatively lightweight and the crown portion can loosely drape into a relaxed shape. The closure for each pocket can be a zipper, Velcro, snaps or other suitable closure. The side portions of the hat have two layers of fabric forming the walls of the pocket. The visor has two layers of fabric with a middle layer of stiffening material. In some embodiments, the side portions and visor fabrics are of different colors and/or materials on the pocketed and unpocketed side of the hat. In some embodiments, the visor is detachably coupled to the front portion.

Abstract: A reversible garment has a reversible pocket attached at a seam thereof. The pocket has a pouch formed by a long pocket piece and a short pocket piece. The curved portions of the pocket pieces are sewn together and their seam is enclosed by another seam. The flat portion of the long pocket piece is attached to the seam of the reversible garment, and centered on an opening in the garment seam. When the garment is reversed, the pocket is pulled through the seam and the pocket pouch is turned inside out, so that the pocket pouch is accessible from the opening in the garment seam, whether the garment is worn with its front side as the outside or its back side as the outside.

Abstract: An improved reversible zipper fly cover is provided having a symmetric reversible zipper fly cover, being symmetric whether formed “inside” or “outside”. A zipper flap is formed symmetrically about each panel and the attachment strips of the zipper attached thereto by stitching. Next, the inner fly flap is formed by stitching one flap to its respective panel; and, the outer fly flap is thereafter formed by stitching the next flap to its respective panel. A crotch seam is thereafter extended laterally downward in an otherwise conventional manner.

Abstract: Reversible denim jacket and pants are disclosed, comprised of a pant and jacket combination, made from denim, and designed to be reversible and fashionable. Unique stitching and fastening means adds to the functionality and usability of the present invention.
