Abstract: A method and system for user-friendly point of care assay is described. The cartridge utilizes a lateral flow assay, buffer chambers and capillary sample collection. The sample is first collected by the capillary tube attached to the cartridge. The cartridge is then actuated, drawing the sample into the lateral flow strip and introducing a buffer liquid into the system thereby automatically performing the assay. An electronic reader may be used to measure the results of the assay.

Abstract: A snowboard binding for securing a boot to a snowboard includes a base that is mounted on the snowboard. The base includes a base plate and a pair of side rails that extend upwardly from the base plate along lateral sides of the base plate. The snowboard binding further includes a high-back support secured to the pair of side rails. The high-back support is fabricated from a single piece of material and has a hinge formed therein to adjust a forward lean position of the high-back support. Additional design features and methods are disclosed herein.

Abstract: A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is comprised of at least two distinct materials with different stiffnesses to achieve a desired blend of stiffness and flexibility. The highback may employ a material of greater stiffness in one or more regions to provide high force transmission between the rider and-the board. The highback may employ a material of lesser stiffness in one or more regions where flexibility is desired for more gradual power transmission, comfort and/or to facilitate highback adjustability. The arrangement of the different materials provides a lightweight highback with a relatively sleek profile having selected regions of stiffness and/or flexibility.

Abstract: A highback for controlling a gliding board, such as a snowboard, through leg movement of a rider. The highback is comprised of an upright support member including at least two portions that are to be contacted by and to support a rear portion of the rider's leg and that are movable relative to each other for setting a desired forward lean of the highback. The support member may include a lower portion with a pair of mounting locations for mounting the highback to a gliding board component, such as a snowboard binding, and an upper portion movably supported by the lower portion to vary the forward lean of the highback. The lower portion of the support member may be mounted to a snowboard binding baseplate for lateral rotation between a plurality of lateral positions. The highback may include a forward lean adjuster that prevents the upper portion from moving in the heel direction beyond a predetermined forward lean position.

Abstract: A snowboard binding mechanism for securing a snowboard boot to a snowboard includes at least one moveable engagement member having an open position and at least one closed position. When in the closed position, the engagement member is biased toward the open position. As a result, when a snowboard boot is not disposed in the binding mechanism, the binding mechanism automatically moves to the open position. The engagement member may also function to compensate for snow, ice or debris accumulated beneath the boot. A single handle may be operatively connected to the engagement members to facilitate ease of removal of the snowboard boot from the binding by simply requiring actuation of the single handle to unlock the binding. A separate foot pedal may be operably coupled to the engagement member and is also employed to unlock the binding. The binding mechanism may also include a cocking feature that unlocks the binding mechanism without also causing the engagement members to move to open positions.

Abstract: An exhaust system baffling apparatus is provided. The apparatus includes a tube with at least one end that is not open. The apparatus further includes a plurality of C-shaped flanges in surrounding relation about the tube. The outer edges of the flanges have a contour which generally corresponds to a contour of an inner surface of a wall of an exhaust pipe. Opposed portions of the flanges adjacent the slits of the flanges are spread apart along the tube in a longitudinal direction. In addition, the opposed portions of the flanges adjacent the slits are angled in opposite directions and extend radially from the tube at a non-perpendicular angle with respect to the tube. At least two of the flanges include brackets adjacent the outer edges of the flanges, wherein the brackets are adapted for securing the apparatus to an interior portion of the exhaust pipe.

Abstract: One embodiment is directed to a snowboard binding including a base having a toe end and a heel end, and a guide that is adapted to guide a snowboard boot back toward the heel end of the base when the snowboard boot is stepped into the binding. Another embodiment is directed to a snowboard; binding including a baseplate and a heel hoop hinged for rotation relative to the baseplate. A further embodiment is directed a snowboard binding to mount a snowboard boot to a snowboard, the snowboard boot including at least one pin extending from medial and lateral sides thereof. The snowboard binding comprises a base having medial and lateral sides; a pair of engagement cams each mounted to one of the medial and lateral sides for rotation between open and closed positions; at least one lever to move the pair of engagement cams from the closed position to the open position; and a cocking mechanism that is adapted to maintain the pair of engagement cams in the open position upon release of the at least one lever.

Abstract: A system for tool free disengagement of an engagement member from a base while the base is mounted to a substrate, so that the engagement member may be repositioned, tool free, in a new mounting location. The engagement member and the base include complementary locking members, and the engagement member may be constructed so that manipulation of the engagement member releases the complementary locking members allowing relocation of the engagement member in a new mounting location. The system may be incorporated in a binding for securing a foot or a boot and in footwear.
