Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: Lyophilized formulations comprising a compound of Formula (I) and one or more amino acids are provided, wherein W, X, Y, Z, Ra, Rc, and each Rg are as defined herein. Also provided are methods of preparation, methods of use, and dosage forms.

Abstract: A massage pad includes a body having a certain thickness, and the body includes a first face and a second face which is located opposite to the first face. The first face has multiple protrusions integrally formed thereon. Each protrusion has a root portion and a rounded portion which is integrally formed with the root portion. The root portion of each protrusion extends from the first face of the body. The diameter of each rounded portion is between 2 mm to 6 mm. The deformation rate of the rounded portion is less than that of the root portion of each protrusion so as to maintain the ball shape to provide better massage feature.

Abstract: A method for making a yoga towel includes a step of preparing a towel with multiple apertures defined therethrough, a resilient plate placed on the towel; a step of placing the towel and the resilient plate between a top mold and a bottom mold which has cavities defined therethrough; a step of heating and softening the resilient plate and matching the top mold to the bottom mold, and a step of vacuuming to suck the softened resilient plate to form anti-slip protrusions on the second face of the towel via the apertures. The anti-slip protrusions are integrally formed with the towel and have elasticity.

Abstract: A pad includes a fabric, a first foam layer and a second foam layer. The second foam layer is located beneath the fabric and has multiple holes defined through the top and the bottom thereof. The second foam layer has a recessed area defined in the top thereof and a path is in communication with the recessed area and the underside of the second foam layer. The fabric is engaged with the recessed area and a periphery of the fabric extends through the path and is located at the underside of the second foam layer. The underside of the fabric that is located at the underside of the second foam layer and the underside of the second foam layer located corresponding to the recessed area are securely connected to a top of the first foam layer.

Abstract: A molding set includes an upper mold and a lower mold. At least one first molding part and at least one second molding part are located on the upper and/or lower mold. The at least one first molding part and at least one second molding part have patterns defined in a surface thereof, and the at least one first molding part and at least one second molding part have different coefficients of heat isolation. By the different coefficients of heat isolation, the foam products include 3-dimentional patterns formed thereon and the 3-dimentional patterns have different levels of density change.

Abstract: A method for making three dimensional convex patterns on foam material includes a step of preparing a first netted fabric which includes first holes, a step of spreading a layer of ink on the first netted fabric, a step of overlapping the first netted fabric on a second netted fabric which includes second holes larger than the first holes, and a step of printing the layer of ink on a foam material by a molding set.

Abstract: In a foam imprinting method, a foam material and a mesh fabric material having messes are prepared; a foaming process is performed and a printing ink layer is coated onto the mesh fabric material when the foam material is not foamed completely, such that the printing ink layer is stacked onto the incompletely foamed material; the foam material, mesh fabric material, and printing ink layer are thermally pressed, and the incompletely foamed material continues its foaming to form protrusions on the meshes, and the printing ink layer is sublimated and permeated into the foam material to complete the imprint. After the mesh fabric material is torn away, a three-dimensional non-slip pattern is formed on the foam material to produce a product with the imprint pattern. The pattern and color of the printing ink layer will not fall off or peeled easily.

Abstract: A floor assembly includes a plurality of floor units and each of the floor units has four sides. Four recesses are defined in four corners of each of the floor units and the floor units are connected with each other side by side. A plurality of fixed members are fixed on the ground and engaged with the recesses of the floor units.

Abstract: A cushion pad includes a stuff item covered by a surface member and the stuff item is supported on a stiff board. The surface member is connected to the stiff board along a top surface around the stuff item and a circumferential surface of the stiff board. A bottom member is connected to an underside of the stiff board and the surface member not covering the stuff item.
