Abstract: An expandable orthopedic implant includes a casing pipe, a shaft, a first expandable element and a first link lever. The casing pipe has a first opening, a second opening and an axis passing through the first and second opening. The casing pipe sheathes one end of the shaft, and the other end of the shaft has a top portion disposed out of the first opening. The first expandable element has a first terminal pivoted on the casing pipe and a second terminal. The first link lever has a proximal end pivoted to the top portion and a distal end pivoted to the second terminal. When the top portion is driven moving away from the first opening along an extending direction of the axis, the first link-lever can be pushed by the shaft to enact the second terminal moving away from the axis along a direction perpendicular to the axis.

Abstract: The present invention provides an optical head with a single or multiple sub-wavelength light beams, which can be used in arenas such as photolithography, optical storage, optical microscopy, to name a few. The present invention includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit.
