Instrument and implants are disclosed which provide for insertion of an implant into an intervertebral disc space from multiple approaches to the spine. Specifically, as a preferred aspect of the invention the implant includes a tapered portion and the implant may be inserted from multiple approaches to the spine with the orientation and taper properly oriented in the disc space regardless of the approach.

An apparatus for stabilizing vertebrae while permitting a range of motion therebetween may include first and second fasteners for engaging adjacent vertebrae and a motion preserving device that can be coupled to the first and second fasteners. The motion preserving device may include a longitudinal member that includes an array of load-bearing elements. The longitudinal member may be configured to permit the load-bearing elements to move relative to each other and / or relative to other portions of the member. In some embodiments, the longitudinal member is relatively inflexible along a longitudinal axis and relatively flexible in a direction transverse to the longitudinal axis.

The invention provides a method for removing cracks of Rene104 nickel-based superalloy during laser additive manufacturing, and belongs to the fields of additive manufacturing and superalloy. Aiming at solving the problem that cracks are liable to occur to Rene104 nickel-based superalloy with a high Al content and a high Ti content (Al+Ti>5%) during laser additive manufacturing, by designing laserforming parameters and sub-regional scanning strategies, generation of large-size cracks in a formed part is suppressed; then stress relief annealing is used for completely removing residual stress in the formed part; and discharge plasma sintering treatment is adopted for removing the cracks in the formed part, and grain growth during the sintering process is suppressed. The scheme that after the formed part is obtained through laser additive manufacturing, in combination with stress relief annealing and discharge plasma sintering treatment, the cracks in the formed part are removed is proposed for the first time. By using the method for preparing the Rene104 nickel-based superalloy with the high Al content and high Ti content, no cracks are found in the formed part, and the tensile strength of the formed part at the room temperature can reach 1300 MPa or higher.

Methods of packaging semiconductor light emitting devices include providing a substrate having the semiconductor light emitting device on a front face thereof. A first optical element is formed from a first material on the front face proximate the semiconductor light emitting device. A second optical element is formed from a second material, different from the first material, over the semiconductor light emitting device and the first optical element. The first optical element and / or the second optical element are formed by compression molding the respective optical element.

A therapeutic method in which plural points on the body are stimulated by light of different wavelengths emitted from wands, probes or other applicators under the control of a central microprocessor. The microprocessor executes program instructions to produce light at each applicator whose intensity, frequency, duration and pulsation accord with protocols which are automatically selected depending on the portion of the body being treated. The protocols can be manually overridden by the therapist, in which case the changed parameters are stored in memory. The apparatus is particularly useful in performing traditional therapeutic methods to treat internal disorders, substance abuse, pediatric and podiatric problems and disorders of the ear, nose, throat, as well as musculoskeletal, neurological or dermatological disorders.

A protection part comprising at least two layers including an outer layer and an inner layer has its outer layer made of an aluminum alloy that is reinforced with particles of SiC, the SiC particle content in said alloy lying in the range 15% to 40% by weight, while the inner layer is made of an aluminum alloy that is optionally reinforced with SiC particles, the SiC particle content within the layers increasing from the inner layer towards the outer layer. The part is for use in protecting the leading edge of a blade, in particular a blade or vane in a turbomachine, a helicopter blade, or a propeller blade.

An optical functional film comprises a multilayer film formed by stacking a plurality of films. The plurality of films are formed by a same material and refractive indices of adjacent films are different.

An apparatus and method for machining of thin panels, in particular, panels having a complex shape, specifically non-deformable panels, in which the panel to be machined is placed beforehand in an isostatic position, characterized by: one defines one or more areas of a predetermined extent for purposes of machining, named machining windows, in the area of the panel to be machined; and perpendicular to each machining window; one of surfaces of panel is held in position without introducing positioning hyperstatism; the actual shape of the aforementioned surface is measured; the desired machining operation is performed on the opposite surface by taking the aforementioned measured surface as a reference; and the aforementioned surface is released.
