A method of making a planar lightwave circuit (PLC) waveguide capable of being integrated with a surface-mounted component is presented. The method entails etching a silicon substrate to form a slanted wall, forming a nonreflective waveguide portion on the silicon substrate, and depositing a reflective layer on the slanted wall. Light travels through the nonreflective waveguide portion in substantially a first direction, and the light from the nonreflective waveguide portion strikes the reflective layer to be redirected in a second direction. The second direction may be the direction toward the surface-mounted component. A PLC waveguide device made with the above method is also presented.

A method and apparatus for performing assays in a single step which does not require the user to perform a washing step, does not require the user to add any reagent or other solution other than analyte sample fluid to the apparatus, and does not require the user to come into contact with the apparatus at any point during the assay procedure after the fluid suspected of containing a particular ligand is added to the apparatus. The apparatus for performing the assay consists of a single container with at least three ports disposed through different planes in the body of the apparatus beneath which labelled antiligand (the first port), unlabelled antiligand (the second port), and unlabelled ligand (the third port) are disposed. Said labelled antiligand is complementary to both the analyte of interest and the unlabelled ligand, the latter of which serves as a control display for comparison of any color changes mediated by the label visible through the second port. The antiligands and ligands disposed beneath each port are bound to separate membranes.

A looseleaf binder assembly consisting of a backbone member and a second member that has fastened thereon a plurality of resilient rounded fingers in a position that will accept a plurality of loose sheets is disclosed. The second member contains an inwardly facing continuous flange on the body of the second member and inwardly facing tangs on the end of each resilient finger. These tangs and continuous flange slide into the grooves of the backbone member until each member is substantially aligned. The two members lock in position, when in alignment, by two of the resilient fingers snapping into notches in the grooves of the backbone member. In order to remove the looseleaf sheets, the two resilient fingers are deflected outwardly to allow the two tangs to clear the two notches where the continuous flange of the second member and the remaining tangs on the resilient fingers can slide out of the grooves in the backbone member.

Methods and systems for use in automating or assisting umpiring of a baseball or softball game are described herein. A location of a strike zone is determined based on video images of a batter standing next to home plate captured by a camera. Locations of a ball traveling towards the batter, and locations of the bat being held by the batter, are autonomously tracked using computer vision based on video images captured by at least two cameras having different positions. Additionally, there are autonomous determinations of whether a location of the ball intersects with the strike zone, and whether the batter made a genuine attempt to swing the bat at the ball, and based one at least one of these determinations, there is an autonomous determination of whether a “strike” or a “ball” occurred. Additionally, an indication of whether a “strike” or a “ball” occurred is autonomously output.
