Abstract: An assembly includes a first sterile adapter and a sterile drape. The first sterile adapter is configured to be received by a first movable robotic arm of a robotic surgical system. The sterile drape includes a first sleeve configured to extend over the first movable robotic arm. The first sleeve includes a first end, a second end disposed opposite the first end, and an intermediate portion disposed between the first and second ends. The first end is coupled with the first sterile adapter. The first end is inverted toward the second end. The intermediate portion includes a first roll.

Abstract: A process produces a glass overcladding tube from a silica gel body. The process includes passing the gel body through a hot zone under conditions that cause partial sintering of the gel body and repassing the gel body through the hot zone under conditions that further sinter the gel body into a glass overcladding tube.

Abstract: An improved technique for assembling and drawing fiber from preforms is provided. In one embodiment, the technique involves providing a core rod assembly comprising a core rod and a bushing attached at an end of the assembly. The core rod assembly is inserted into an unsintered overcladding tube, and secured to the tube such that the core rod assembly is suspended within. The overcladding tube and the core rod assembly are heated to sinter the overcladding tube and thereby form a preform assembly. During the heating step, the bushing comes into contact with the interior of the overcladding tube, and, because the bushing has a larger diameter than the core rod, an annular gap is maintained between the core rod assembly and the interior of the overcladding tube. It is then possible to attach a draw handle to the preform assembly, place the preform assembly into a draw tower, and draw fiber from the preform assembly by an overclad during draw technique.

Abstract: A photoelectrochemical etching process is described for producing gratings in various semiconductors. Because this is a direct, single step process, extreme uniformity is obtained over a wide area. The procedure is particularly useful for mode reflection in distributed feedback lasers.
