A nanowire switching device and method. The device has a nanowire structure comprising an elongated member having a cross-sectional area ranging from about 1 nanometers but less than about 500 nanometers, but can also be at other dimensions, which vary or are substantially constant or any combination of these. The device also has a first terminal coupled to a first portion of the nanowire structure; and a second terminal coupled to a second portion of the nanowire structure. The second portion of the nanowire structure is disposed spatially from the first portion of the nanowire structure. An active surface structure is coupled to the nanowire structure. The active surface structure extends from the first portion to the second portion along the elongated member.

A pile article having a support strand for attachment to multifilament yarn to form a velour-like pile having loosely entangled filaments in spaced apart monolithic pile rows, a helically wound package of oriented pile articles for shipping and storage, and a pile surface structure comprising pile articles arranged in spaced apart rows on a substrate to form a pile surface that may be flat or moldable, and a method for making a pile surface structure by embedding the pile articles into the backing substrate. The pile surface structures may be usefully employed in automobile mats, carpets and panels.

A 3-D reconstruction method based on Taylor exponent expression surface structured light is provided, The method mainly comprises the following steps: generating and projecting a surface structure grating based on a special exponential expression, acquiring an image, and calculating the phase information of a projector-free gamma error contained in the acquired image based on a corresponding novelphase decomposition method. Thus, through the phase information of no projector gamma error, calculating the three-dimensional measurement result, and eliminating the effect of projector gamma on themeasurement result, and improving the measurement precision.

The present invention relates to a method for reinforcing reinforced concrete structure by externally riveting steel plate and its special-purpose rivet. The reinforcing steel plate strip can be riveted on the surface of the concrete member from exterior of the concrete member, and the described rivet is made into the form of that the half of the rivet head of said rivet is semicylindrical form, and another half of semiconical form, and the cross-section of said rivet body is rectangular, and the transition portions between four planes of rivet head and rivet body are made into the oblique surface structure.

The invention relates to a superconducting automatic opening and closing type pressure releasing explosion-proof door and belong to the explosion-proof field. The door comprises connecting pieces, conveying pipelines, a return spring, a middle guide rod, a valve cap, a permanent magnet, a primary sucker, an auxiliary sucker, a force nut, a guide cylinder, a sucker shelf and sealing strips. The door adopts the guide cylinder of a cylindrical surface structure, so that locating is accurate, the guide is smooth, jamming does not take place and the occurrences of onsite breakdown and shutdown are prevented; the door also adopts a design of two inclined planes between which the interference is even smaller, so that the seal is stable and the effect is remarkable. The sucker shelf of the door adopts a conical structure design, on one hand, the structure is firmer and on the other hand, the explosion-proof effect is more stable, pulverized coal is not easy to accumulate and the production is reliable.
