An improved system for confocal imaging within dermal tissue of a patient is provided which minimizes instability in confocal images by reducing the relative motion of the tissue with respect to the confocal imaging optics of the system. The system includes a mechanism for maintaining an area of skin tissue under stress by application of force at the edges of the area, and an imaging head coupled to this mechanism for imaging the stressed skin. The mechanism includes a mechanical structure, such as a platen, brace, or attachment, which both supports the imaging head of the system and applies stress to a limited surface area of the tissue to minimize skin motion during confocal imaging.

The invention relates to a manufacturing method of a titanium alloy thin-wall ribbed hollow component. The method comprises the following steps that: a. the titanium alloy hollow component is decomposed into a stressed-skin and ribbed structure form or a stressed-skin ribbed structure form according to the structure features of a hollow component, and an inner sheath and an outer sheath structure forms are determined according to a hollow part of the hollow component; b. the stressed-skin and ribbed or the stressed-skin ribbed structural part is processed or formed according to the decomposed structure forms; c. the inner and the outer sheaths are processed or formed; d. the stressed-skin and ribbed or the stressed-skin ribbed structural part being well processed is assembled with the inner and the outer sheaths, the inner and the outer sheaths are sealed in a welding way and are vacuum encapsulated, and the vacuum degree is 1.0 *10-3Pa; e. the dispersion connection of each structural part is realized through a hot isostatic pressing method; f. surface treatment on each prefabricated structural part is undertaken so as to prepare the hollow structural component. The manufacturing method has high production efficiency; a plurality of components can be prepared through one technical circulation; and the welding rate is more than 95 percent.

The invention relates to a prefabricated non-thermal bridge external thermal insulation wallboard with a C-shaped steel light steel keel and a manufacturing method thereof. The wallboard comprises a base wall body, a break thermal bridge anchoring bolt, a connecting piece, a thermal insulation board and a stressed-skin diaphragm. The thermal insulation board and the base wall body are fixedly connected into a whole through the break thermal bridge anchoring bolt and the connecting piece, and the stressed-skin diaphragm is fixedly arranged on the other side, relative to the thermal insulation board, of the base wall body. The prefabricated non-thermal bridge external thermal insulation wallboard is convenient to construct and simple in structure, breaks the inherent concept of ''thermal insulation after wall body'' and proposes the integrated production of a thermal insulation wall body. Factory prefabrication and site assembly can be carried out, batch production and on-site installation are convenient, the construction efficiency is improved, the characteristics of low energy consumption, flexible arrangement and fast construction are achieved, and the requirements of green construction are met. The arrangement of the non-cut-through type break thermal bridge anchoring bolt and dovetail grooves avoids the phenomenon of a thermal bridge caused by joints and the like, the thermal insulation performance of the wall body is improved, and the structural integrity is increased; and the weight of the wall body is greatly reduced due to using of a light steel keel frame and lightweight concrete, and the cost of construction, transportation and seismic design of later structure is reduced.

A solar panel system comprises a monocoque forming an enlarged solar-facing generally-convex outer support surface when in an installed position and that supports solar cells at optimal angles for capturing solar energy. The monocoque provides a stressed-skin support reducing weight while maintaining strength, optimal support surface, and minimizing cost. A post engages and supports adjacent edges of a pair of adjacent monocoques. An electrical circuit connects the solar cells for electrical flow and power management, and preferably includes a controller for controlling power from the solar cells, including combining them in series or parallel as optimal for a given systems configuration. The illustrated monocoque includes a roll formed sheet or a number of sheets, stacked vertically together and anchored to spaced posts using connectors in a “fence-like” pattern.

The invention provides a dynamic BOTDA-based multi-core cycle series-connection fiber-shaped sensor. The fiber-shaped sensor comprises a multi-core fiber, a single-mode fiber and multi-core fiber Fan-in device, a single-mode fiber and multi-core fiber Fan-out device and a plurality of single-mode fibers, wherein the plurality of single-mode fibers are connected between the Fan-in device and the Fan-out device. By a mode of sequentially and circularly connecting a plurality of fiber cores of a multi-core fiber in series, the function of expanding the plurality of fiber cores to form a one-dimensional topological optical path is achieved. The fiber-shaped sensor can used for a shape sensing device of a dynamic BOTDA sensing system, can be widely used for monitoring health of an intelligent structure and also can be used for a stressed skin structure of a robot or an airplane wing, and the shape change thereof is detected in real time.
