Abstract:
Disclosed is a pressure-sensitive adhesive matrix patch device for treatment or prevention of fungal toenails or fingernails or foot infections comprising an antifungal agent or two or more antifungals in combination and adhesively secured to a dorsal site of an infected palm or foot, rather than an area of infection and surrounding skin. A method for the transdermal treatment or prevention of fungal toenails or fingernails or foot infections with an antifungal agent is also disclosed, the method comprising adhesively securing to a dorsal site of an infected palm or foot a pressure-sensitive adhesive matrix patch device for a time sufficient to deliver an effective amount of the antifungal agent to an area of infection.
Abstract:
A medical light device includes a main body, a light source, a filler, and a contact part. A cavity, receiving a light source, is disposed on the main body. The filler is composed of transparent material, filled inside the cavity, and covers the light source. The contact part, composed of soft and transparent material, is placed adjacent to the filler, covering the surface of the filler. The refractive index difference between the contact part and the filler is smaller than the refractive index difference between the filler and air.

A conductive winding module is used in a magnetic element. The conductive winding module includes multiple conductive units and multiple output terminals. The conductive units have respective hollow portions. The output terminals are arranged on the conductive units. The conductive units are folded with respect to a connecting line between the conductive units such that the hollow portions are aligned with each other to define a through-hole and the multiple output terminals are staggered to form at least three output terminals to be inserted into a circuit board.

Abstract:
A method for monitoring a manufacturing process features acquiring metrology data for semiconductor wafers at the conclusion of a final process step for the manufacturing process (“Step a”). Data is acquired for a plurality of process variables for a first process step for manufacturing semiconductor wafers (“Step b”). A first mathematical model of the first process step is created based on the metrology data and the acquired data for the plurality of process variables for the first process step (“Step c”). Steps b and c are repeated for at least a second process step for manufacturing the semiconductor wafers (“Step d”). An nth mathematical model is created based on the metrology data and the data for the plurality of process variables for each of the n process steps (“Step e”). A top level mathematical model is created based on the metrology data and the models created by steps c, d and e (“Step f”). The top level mathematical model of Step f is based on those process variables that have a substantial effect on the metrology data.
