Abstract: A guide rail type shielding curtain, comprising guide rail type moving mechanism, shielding curtain frame, first stretching bearing mechanism and second stretching bearing mechanism. Guide rail type moving mechanism comprises first guide rail sliding grooves and first guide rail sliding strips, which are arranged on the inner sides of automobile side plates on two sides; curtain frame mounting holes are formed in front ends of first guide rail sliding grooves; shielding curtain frame is mounted in left and right curtain frame mounting holes; stretching limiting transverse strip is provided on the rear side of first stretching bearing mechanism; first guide rail sliding strip holes are formed on left end and right end of stretching limiting transverse strip respectively; first guide rail sliding strips are arranged in first guide rail sliding strip holes; pulleys are movably arranged at the outer ends of the first guide rail sliding strips.

Abstract: A folding lifting device for automobile, comprising outer housing, lifting supporting plate, folding assembly and synchronous cushioning assembly. Outer housing comprises housing bottom, lifting supporting plate is provided in outer housing, and folding assembly is provided between lower side of lifting supporting plate and upper side of housing bottom; folding assembly is composed of two groups of same side V-shaped folding elements, and synchronous cushioning assembly is provided between lower sides of two groups of side V-shaped folding elements. Each of two groups of side V-shaped folding elements comprises front upper folding bar, front lower folding bar, rear upper folding bar and rear lower folding bar; first synchronous rack is fixedly provided at rear side of front lower folding bar, second synchronous rack is fixedly provided at the front side of the rear lower folding bar.

Abstract: Microparticles actively propel through the vitreous humour and reach the retina in porcine eyes. The slippery micro helical propellers are constructed by the combination of glancing angle deposition technique and the fusion of the slippery liquid layer. The magnetically propulsion in the vitreous humour relies on the matched size of the propeller to the collagen network of the vitreous, and the anti-adhesion coating of the collagen fiber bundles. Clinical optical coherence tomography observed the displacement of the slippery micropropellers through the vitreous to the macular area on the retina. The slippery micropropellers realize the controllable massive movements to the retina in 30 mins, while exerting the travelling distance of above one centimeter.

Abstract: Image-guided microrobotic systems, methods and methods that employ micromotor(s) having imaging agent(s) and cargo in a microcapsule, each micromotor having a partial coating over a reactive particle and/or asymmetrical geometry, when activated the microcapsule disintegrates releasing the micromotor(s) and active propulsion is generated when fluid contacts the reactive particle.
