摘要:
A stand for medical optical instrument capable of easily extending, adjusting easily a counter balancing according to a change of a weight of medical optical instrument such as microscope, as well as, maintaining stably a counter balancing regardless of a position of medical optical instrument. The stand for medical optical instrument includes: a carrier arm including a first to fourth links having a first to fourth turning joins, wherein the first to fourth links are rotatably coupled to each other in a parallelogram shape and the second turning joint is rotatably coupled to a holding unit, and a front link extended from the fourth link; and a counter balancing unit coupled to the first and second links, wherein the counter balancing unit is rotated in connection with the first and second links on the second turning joint according to the rotation of the carrier arm, and capable of maintaining a counter balancing of the carrier arm by compensating a torque generated in the second turning joint by a medical optical instrument installed on the front link.

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.
摘要:
Provided is a method of arranging particles on a substrate, the method including: (a) preparing a substrate, a surface of which has depressions or projections capable of fixing the positions and/or orientations of one or more particles; and (b) placing the particles on the substrate and applying a physical pressure to the particles so that a portion or the whole of each particle is inserted in each of pores defined by the depressions or the projections. Provided is also a method of arranging particles on a substrate, the method including: (a) preparing a substrate, at least a surface portion of which has adhesive property; and (b) placing particles, which do not have flat facets but curved surfaces, on the substrate and applying a physical pressure to the particles so that the particles are immobilized on adhesive surface portions of the substrate.
