Abstract: The present disclosure provides a system for processing ultramafic material. The system may comprise a reactor for accelerating weathering of said ultramafic material. The reactor may comprise one or more chambers comprising one or more microbes, biological medicators, or enzymatic accelerants to facilitate the weathering of the ultramafic material.

Abstract: A lighting fixture arrangement, an adjustable lighting fixture connector, and a method of installing a lighting fixture arrangement.

Abstract: Methods for tissue repairs with direct pass cinch are disclosed. A direct pass cinch is created with a suturing construct using only one portal and without shuttling steps. The suturing construct may be a loop terminating in a single tail.

Abstract: Techniques, mixtures, mixing and delivery kits, and improved delivery instruments for implantation of micronized allograft tissue over a microfractured defect. Allograft cartilage tissue is delivered over a cartilage defect that has been debrided and microfractured, without the need for a periosteal covering or separate type of patch sewn over the top. The allograft tissue may be any micronized cartilage particulates obtained by various methods, for example, cartilage delivered in its native form, dehydrated via lyophilization, “freeze-dried,” dehydrated via desiccation, or dehydrated by any other method.

Abstract: A telephone headset is provided which includes a presence status indicator thereon for signaling to other persons the user's availability and/or willingness to communicate face-to-face.

Abstract: A marker adapted to be wrapped around a pipe, the marker comprising a sheet, the sheet having a plurality of spaced apart dimples therein. The dimples are in rows, and each dimple is shaped like a part of a sphere and is staggered midway relative to the preceding row. The sheet is flexible and curved, and the sheet bears indicia.

Abstract: An actively Q-switched laser based on UV illumination mitigates pyroelectric effects in lithium niobate. An exemplary embodiment comprises a pump source; a dichroic mirror having one end optically facing said pump source; a gain medium optically facing another end of said dichroic mirror; a polarizer having one end optically facing another end of said gain medium; a quarter wave plate having one end optically facing another end of said polarizer; and a electro-optic crystal having one end optically facing said quarter wave plate, at least one side of said electro-optic crystal being electrically connected to Q-switch driver to have the crystal function as a Q-switch. A UV illumination source illuminates a side surface of said electrical-optic crystal with UV light. An output mirror receives an output from said Q-switch and produces a laser emission.

Abstract: A method and device for reducing the timing jitter in a passive Q-switched Nd:YAG solid state laser by spatially selective bleaching a thin sheet of a saturable absorber of Cr+4:YAG from a direction orthogonal to the direction of laser emission where the Cr+4:YAG transmission increases 18% when the bleaching probe beam is a single laser diode bar. For steady state operation of a passive Q-switched laser, the pulse-to-pulse timing jitter showed a ?12× reduction in standard deviation from 241 nsec for free running operation to 20 nsec with optical triggering.

Abstract: The invention is directed toward a surgical forceps comprising a pair of scissor arms connected together by a pivot where the proximal ends forms a hand grasping surface and the distal ends are provided with jaw members. Each jaw member has a curved inner surface with a plurality of teeth and measurement markings at spaced intervals along an end surface of the first and second jaws. Each jaw member is semi-circular in shape and extends outward from each respective arm at an angle of about 110° so that when said scissor arms are closed together the jaw ends move toward each other. A rachet assembly is mounted on one scissor arm to engage a pawl mounted on the other arm to lock the jaw members in a fixed position.

Abstract: A modified silica glass composition for providing a reduction in the multiphonon quenching for a rare-earth dopant comprising: SiO2 in a host material; a rare-earth dopant; a first SiO2 modifier; and a second SiO2 modifier; such that said first modifier and said second modifier reduce multiphonon quenching of the rare-earth dopant contained therein.

Abstract: An arrow that is easily assembled and exhibits improved concentricity between the arrowhead and the arrow shaft includes a hollow arrow shaft, an arrowhead having a tip and a cylindrical shank, and a bushing having a cylindrical section and a tapered section, wherein the cylindrical section of the bushing is received in an end of the hollow arrow shaft and secured to the hollow arrow shaft with an adhesive. The tapered section has a bore in which the shank portion of the arrowhead is received, and the shank portion of the arrowhead is secured within the bore using an adhesive. In accordance with an aspect of the invention, the cylindrical shank portion of the arrowhead has smooth surfaces that engage smooth surfaces of the bore extending through the tapered section of the bushing, whereby the absence of threads and other irregularities on the engaging surfaces between the arrowhead and the bushing improve concentricity among the arrowhead, bushing and arrow shaft.
