    Abstract: A sterilization process challenge pack including a base tray, a first cover, and a second cover is configured to provide a restrictive flow path for gaseous sterilization medium to test the efficacy of a sterilization process. The base tray includes at least one chamber containing a biological indicator and/or chemical indicator. The first cover including a notch is configured to cover the at least one chamber. The second cover is attached to peripheral surfaces of the base tray except at an unsealed portion. A flow path through the unsealed portion and the notch in the first cover provides the only fluid communication between an external environment and the at least one chamber.

    Abstract: A liquid sporulation method is described. A first liquid culture is prepared by adding bacterial cells to a sporulation broth, wherein an optical density (OD600) of the first liquid culture is in a range of 0.001 to 0.01. The first liquid culture is incubated and an optical density (OD600) thereof is increased to be in a range of 0.2 to 2.0. Second liquid culture is prepared by adding the incubated first liquid culture to a predetermined amount of additional sporulation broth, wherein an optical density (OD600) of the second liquid culture is in the range of 0.001 to 0.1, and a ratio of a volume of the second liquid culture to a volume of the first liquid culture is in a range of 10:1 to 150:1. The second liquid culture is incubated so an optical density (OD600) thereof is increased to be in a range of 1.0 to 4.0.

    Abstract: A system for identification of abnormalities related to illumination of a target and automatic compensation therefor includes a lighthead and a controller. The lighthead is configured to illuminate the target. The lighthead includes a plurality of lighting modules configured to emit light therefrom. Each of the lighting modules includes a distance sensor configured to measure a distance from the lighting module to a surface toward which the lighting module is pointed. The controller is configured to identify one or more abnormalities of the measured distances, determine a true distance from the lighthead to the target based on the measured distances, predict an amount of illumination based on the true distance that would be supplied to the target without the identified abnormalities, and compensate for the identified abnormalities by respectively adjusting an amount of light emitted from the lighting modules to illuminate the target according to the predicted amount of illumination.

    Abstract: The present invention relates to phenol containing disinfectants that have superior broad-spectrum antimicrobial efficacy versus traditional chemistry such as quaternary ammonium-containing disinfectants or aliphatic alcohols. Hydrotropic surfactants are utilized in combination with generally environmentally friendly phenol containing compounds such as ortho-benzyl parachlorophenol (OBPCP), ortho phenylphenol (OPP), or parachloro-meta-cresol (PCMC) in the presence of suitable solvents such as an aliphatic alcohol and also in the presence of an inorganic acid, such as phosphoric acid. The solutions are free of para tertiary amylphenol (PTAP), have a low pH and are very stable with respect to gamma irradiation. They can be used with respect to hard surface disinfection, and also as a tuberculocide, a fungicide, a bactericide, and a virucide.

    CPC classification number: F16D65/06 F16D49/00 F16D65/0971 F16D2125/40

    Abstract: A brake screw for use with a surgical lighting system. The brake screw includes a screw member retained within a threaded aperture of a mounting hub of a spindle of an arm used with the lighting system. The screw member is rotationally adjusted to enable displacement in an axial direction. A brake member is in axial alignment with the screw member and disposed for movement in the axial direction against a mounting tube retained within the mounting hub upon rotational adjustment of the screw member. A rivet section is integrally formed with the brake member and has a distal end retained within an axial recess formed within the screw member, allowing movement of the brake member in the axial direction within the screw member. A bias member is disposed between the screw member and the brake member to create a biasing force that urges apart the screw member and the brake member along the axial direction.
