Abstract: A voltage tracking circuit includes first, second, third and fourth transistors. The first transistor is in a first well, and includes a first gate, a first drain and a first source coupled to a first voltage supply. The second transistor includes a second gate, a second drain and a second source. The second source is coupled to the first drain. The second gate is coupled to the first gate and a pad voltage terminal. The second body terminal is coupled to a first node. The third transistor includes a third gate, a third drain and a third source. The fourth transistor includes a fourth gate, a fourth drain and a fourth source. The fourth drain is coupled to the third source. The fourth source is coupled to the pad voltage terminal. The second transistor is in a second well different from the first well, and is separated from the first well in a first direction.

Abstract: An assistive device structure for positioning and pressure relief is provided, including a first elastic layer and a second elastic layer, which are attached by using a high-frequency encapsulation process, sealing, bagging, thermoforming, or an integrally molding process. Each of the first and second elastic layers has a bottom surface and an arc surface disposed opposite to each other. The arc surface includes two protrusions and a recess formed there in between. The two protrusions have different heights. A hollow area is disposed in the recess of the first and second elastic layers. Based on such structure, the bottom surfaces of the first and second elastic layers are attached to form the proposed assistive device structure for a user to lean against and providing multiple positioning effects and pressure relief. More than four axial directions of supporting forces are generated to effectively enhance muscle relaxation and stress relief.

Abstract: A straw biolubricant includes 70-80% mineral oil, 6-11% straw biomass oil, and 15-20% active agent. The active agent is sorbitol oleate. The straw biolubricant includes a higher contact resistance and lower coefficient of friction in comparison with a conventional lubricant, therefore to reduce the temperature of operating machine parts.

Abstract: A molecular film for coating optical lenses comprises Octadecyltrichlorosilane; and a germicide, wherein the weight ratio between the germicide and the Octadecyltrichlorosilane is 3 to 13. Furthermore, a manufacture method of a molecular film for coating optical lenses comprises a step of “preparation”, by preparing a substrate, Octadecyltrichlorosilane solution and a germicide; a step of “cleaning”, by removing olein and contamination from surfaces of the substrate and washing the substrate; and a step of “soaking”, by soaking the substrate in a mixture of the germicide and Octadecyltrichlorosilane solution to generating a molecular film on the surfaces of the substrate.

Abstract: The topography shaping apparatus for forming surfaces of low friction coefficient includes a data-input element, a computing element, and a shaping element. The data-input element is adapted to receive an action length, a fractal dimension value, and a fractal roughness parameter of a desired surface. The computing element connects with the data-input element to obtain a surface topography function from the data received by the data-input element. The shaping element connects with the computing element for processing a target surface to have a sectional outline matching the surface topography function to become the desired surface.
