Abstract: A shot detection system can include a shooting target that is made of paper and printed to include fiducials, borders and a bar code together with a scoring region and markings. A method of camera adjustment control can find and lock onto a target. A target acquisition procedure can include extracting a region of interest (image of the shooting target), calibrating the region of interest and then target locking. The real-time target locking procedure can include correcting an image of the region of interest to account for tilt, rotation and skew. A methodology of shot detection can include acquiring probable and confirming shot candidates and then verifying the probably shot candidate with the confirming shot candidates to substantially eliminate falsely identified shots candidates, thereby significantly improving performance and experience.

Abstract: An adapter and method are described for an internal combustion engine to direct blow-by gasses from a crank case to a catch can where air is cleaned, and then to provide such filtered air back to the motor via a positive crankcase ventilation (PCV) valve.

Abstract: The filter is made of a flat wire with a generally rectangular cross section that has two long sides and two short sides. The flat wire is formed into a generally cylindrical helix defined by successive loops of wire stacked adjacent to one another. For any two successive wire loops, the long sides of the wire loop are set at a predetermined distance from the long side of an adjacent wire loop. Additionally, the short sides of successive wire loops are substantially aligned.
