An apparatus and method for achieving ultrahigh-power output from a solid-state laser. The solid-state laser of the subject invention uses multiple disk-shaped laser gain media (subapertures) placed adjacent to each other to fill an optical aperture of an AMA module. In one preferred embodiment each of the laser gain media is provided with optical coatings for operation in the active mirror configuration. Furthermore, each of the laser gain media is hydrostatic pressure-clamped to a rigid, cooled substrate, which allows it to maintain a prescribed shape even when experiencing significant thermal load. A cooling medium can be provided to a heat exchanger internal to the substrate and / or flowed through the passages on the substrate surface, thereby directly cooling the laser gain medium.

A vehicle wheel, comprising a rim, a hub, a plurality of spokes extending between the rim and hub, a bracing element including a hole with a central axis, a sidewall, a longitudinally inward entrance, and at least one of an engagement surface and an engagement edge outward of the entrance, a connecting element comprising a multiplicity of discreet segments. The bracing element comprises at least a portion of one of the rim and hub. At least one segment includes a laterally projecting overhanging surface. The first segment is positioned within the hole, with the overhang surface overlying one of the engagement surface and engagement edge in an overlie engagement. The second segment is positioned within the hole to include an opening between the first and second segments. The spoke is positioned within the opening and is connected to the connecting element with the overlie engagement to support spoke tensile load.

A single mode fiber having a core, an inner cladding, a depressed cladding, and an outer cladding composed of pure silica glass. The core is surrounded in sequence with the inner cladding and the depressed cladding. The core has silica glass doped with germanium and fluorine, with a diameter (a) of 8.0-8.8 μm, a relative refractive index difference (Δ1) of 0.35-0.38%, and the contribution of fluoride (ΔF) is −0.09±0.02%. The inner cladding has silica glass doped with germanium and fluorine, with a diameter (b) of 18-21 μm and a relative refractive index difference (Δ2) of 0±0.02%. The depressed cladding has silica glass doped with fluorine, with a diameter (c) of 26-36 μm and a relative refractive index difference (Δ32) at the external interface thereof is between −0.22 and −0.35%, and a relative refractive index difference (Δ31) at the internal interface thereof is between −0.20 and −0.35%, and Δ32≦Δ31. The fiber has a good bending resistance, good mechanical properties, and extended service lifetime, and prevents the additional stresses generated by bending from passing on to the core, thereby reducing attenuation.

A fixation device and method for the subcutaneous fixation of bone fragments. A fixation mesh is formed by the intersection of a plurality of linear legs that are interconnected in sagittal planes to form linear sagittal lines and a plurality of crimped legs that are interconnected in transverse planes to form transverse lines. The mesh resists expansive forces that are created in the linear sagittal lines and a compressive stress is created in the transverse lines when tensile loads are applied to the linear sagittal lines resulting in a device that minimizes the gap distance between bone fragments.

A piston for an internal combustion engine, comprising a piston head having a piston crown, a circumferential top land, and a circumferential ring belt having ring grooves. At least one ring groove is provided with a ring insert. A circumferential depression is provided in the top land, above the ring belt.

Devices, kits and methods described herein may be for treatment to skin, including but not limited to wound healing, the treatment, amelioration, and / or prevention of scars or keloids. An applicator and / or tensioning device may be used to apply a dressing to a subject. The applicator and / or tensioning device applies and / or maintains a strain in an elastic dressing, wherein at least some of the strain is out-of-plane or at a non-orthogonal, non-parallel and non-aligned orientation to other strains in the dressing.

Device for winding and unwinding the lower part of fishing line (cast) is a part of equipment for fishing with hook, by which it is solved the problem of visibility in water of lower reinforced parts of lines made of materials visible in water. These parts represent one of the most loaded parts of fishing equipment, because they are subjected to large tensile and gliding stresses. The device includes a two-part housing in which there is the hollow cylinder on which the reinforced lower part of the line is wound by a blade coil spring. In the stage of attracting the fish, the reinforced lower part of the line remains invisible and in the stage of swallowing, tearing and pulling the bait with the device, reinforced lower part of the line is pulled out of the device. The pulled out, reinforced lower part of the line cannot be bitten through or torn off by the fish, that enables the reliable catch. The device is used as the bait and model or insert for natural and artificial fishing baits for fishing predatory freshwater and sea fish.

Devices, kits and methods described herein are provided for treatment to skin, including but not limited to wound healing, the treatment, amelioration, and / or prevention of scars or keloids. A book-like packaging, applicator and / or tensioning device can be used to apply a dressing to a subject. The packaging, applicator and / or tensioning device applies and / or maintain a strain in an elastic dressing, and include undulating edge configurations to reduce peak stresses applied to the skin compared to traditional dressing shapes

In a method of forming a hole on a work piece, a laser beam is directed from a laser head to a predetermined portion of the work piece to form a pilot hole having a first surface condition, and then the predetermined portion of the work piece is punched using a die and a punch having a cross-section greater than a cross-section of the pilot hole. Thus, a finished hole having a cross-section greater than the cross-section of the pilot hole is formed over the pilot hole. The finished hole has a second surface condition, and the second surface condition is formed by transforming the first surface condition by the punch to have a precise dimension.
