Abstract: A cooling tower system includes a gas-liquid contactor having a housing coupled to a plurality of structural members. The system includes one or more basins positioned within the housing, and the one or more basins include a bottom basin. The system includes one or more packing sections positioned at least partially above the bottom basin, a fan operable to circulate a gas through the one or more packing sections, and a liquid distribution system configured to flow a solution onto the one or more packing sections, wherein the gas-liquid contactor comprises one or more materials of construction (MOCs). The plurality of structural members define a plenum comprising a containment that is at least partially segregated from the bottom basin by one or more walls, the bottom basin positioned at least partially below the packing.

Abstract: A method for cutting a bone of a patient using a bone saw tool that includes determining a cutting region that corresponds to a region of the bone to be cut and determining the position of the bone saw tool in the coordinate system. The method includes activating a bone saw blade guard of the bone saw tool if the bone saw tool is outside the cutting region.

Abstract: Patient specific surgical instruments, and in particular cutting guides, and methods of use and manufacture are described. The surgical instrument can be used in an orthopaedic arthroplasty procedure to be carried out on a joint of a patient and can allowing soft tissue balancing for the joint. The instrument comprises a body having an attachment area configured using data specific to a bone of the joint of the patient so as to attach to the bone in a unique position. The instrument includes at least a first cutting guide and an adjustment mechanism operable to change the position of the cutting guide relative to the bone.

Abstract: A customized patient-specific orthopaedic surgical system including a first surgical block, a second surgical block, and a computer-controlled milling machine. The first surgical block includes a first bone-facing surface having a first customized patient-specific negative contour to receive a first corresponding contour of a bone of a patient and a first mounting surface. The second surgical block includes a second bone-facing surface having a second customized patient-specific negative contour to receive a second corresponding contour of the bone of the patient and a second mounting surface to be separately mated with the first mounting surface. The computer-controlled milling machine includes a third mounting surface to be separately mated with the first mounting surface of the first surgical block.

Abstract: A bone saw tool includes a bone saw and a bone saw blade assembly. The bone saw blade assembly includes a bone saw blade and a bone saw blade guard. The bone saw blade guard is movable to an extended position to reduce the cutting effectiveness of the bone saw blade and/or the maximum cutting depth of the bone saw blade. The bone saw may be configured to activate the bone saw blade guard in response to a signal received from a computer system when the bone saw is moved outside a predetermined cutting region.

Abstract: An orthopaedic cutting guide assembly and method of cutting a bone are described. A component has a guide for guiding a cutting instrument and at least a first mechanism for securing the component to a bone. A movement indicator has a mechanism for securing the movement indicator to the bone independently of the component. The component includes at least one indicium by which movement of the component relative to the bone can be indicated by relative movement of the movement indicator and the indicium.
