A soft-solid ear piece is formed to fit the typical human ear canal and will self form to fill the ear cavity by having an internal structure, endoskeleton, or bladder to expand to precisely fit the ear piece securely and comfortably in the ear canal. This self forming ear piece will enable ready-ware and custom molded hearing aids, hearing protectors, audio ear pieces, cell phone ear pieces and assistive listening devices to fit comfortably, securely, and free of acoustic feedback in the external ear canal. It creates an acoustic seal to optimally reduce peripheral leakage and intermodulation distortion delivering excellent acoustic performance while keeping environmental sounds blocked out.

Disclosed is a method for tapping rubber trees by using gas stimulation near the rubber tapping cut. The tapping cut consists of two eighth cuts. The two eighth cuts are arranged along an imaginary specific line and are tapped upwards or downwards. In another option, one notch is tapped upwards, while the other notch is located vertically below it and is tapped downwards. The latex flowing from the two cuts is collected in the latex collection container (9). The gas stimulation includes a dressing device secured adjacent the incision. The applicator consists of a peripheral flange to which is secured a soft sealant fixed at the factory by means of a removable silicone paper.

Soft lithography with surface tension control is used to microfabricate extremely efficient solid immersion lenses (SILs) out of rubber elastomeric material for use in microscope type applications. In order to counteract the surface tension of the mold material in a negative mold that causes creep on a positive mold, material such as RTV is partially cured before use in order to allow the reticulation of polymer chains to change the viscosity of the uncured material in a controllable manner. In a specific embodiment, the techniques of soft lithography with surface tension control are used to make molded SILs out of the elastomer polydimethylsiloxane. The lenses achieve an NA in the range of 1.25. The principle of compound lens design is used to make the first compound solid immersion lens, which is corrected for higher light gathering ability and has a calculated NA=1.32. An important application of these lenses is integrated optics for microfluidic devices, specifically in a handheld rubber microscope for microfluidic flow cytometry.

The invention relates to a method for manufacturing an antique wooden floor, substantially comprising normal working procedures such as texture processing for the surface of a base material, tenons making at two sides, edge jetting, coloring and lacquering. The method is characterized in that: the texture processing for the surface of the base material is an overlay technology that the surface of the base material is pressed into hand-scrapped antique wooden textures with an antique wooden-shaped molding board and a hot pressing machine. The overlay technology that the surface of the base material comprises the specific steps of sorting, sanding, installing a crash pad and the antique wooden-shaped molding board, adjusting technical parameters of hot pressing temperature and hot pressing pressure of the pressing machine, emptying, pressing and shaping, discharging, balancing and staying for 3 days, and then coloring. The method for manufacturing the antique wooden floor has the beneficial effects of canceling traditional abrasion resistant papers and balance papers, directly pressing high-density boards to have the effect of antique wooden texture by the pressing machine; and pressing the antique effect on soft solid wood. The surface of the solid wood composite board base material is pressed into antique wooden effect and scraped into the antique wooden effect and then is lagged, which replaces traditional inefficient method for directly hand-scrapping the solid wood composite floor into the antique floor.
