Abstract: A chainsaw chain includes a plurality of drive links, a plurality of cutters, and a plurality of rivets. Each drive link includes a drive link body, a rivet hole extending through the drive link body, and a tang configured to engage a drive element of a chainsaw. Each cutter includes a cutter body having a rivet hole extending therethrough, a cutting tooth coupled to an upper portion of the cutter body, a carbide cutting tip coupled to the cutting tooth, a feed limiter coupled to the upper portion of the cutter body and spaced from the cutting tooth, and a gullet defined between the cutting tooth and the feed limiter. The plurality of rivets is received within corresponding rivet holes of the plurality of drive links and the plurality of cutters, to couple the plurality of drive links and the plurality of cutters together.

Abstract: A chainsaw chain includes a plurality of drive links, a plurality of cutters, and a plurality of rivets. Each drive link includes a drive link body, a pair of rivet holes extending through the drive link body, and a tang extending from the drive link body and configured to engage a drive element of a chainsaw. Each cutter includes a cutter body having a pair of rivet holes extending therethrough, a cutting tooth coupled to an upper portion of the cutter body, a feed limiter, and a gullet. The cutter body defines a longitudinal axis extending through the pair of rivet holes and a vertical axis oriented perpendicular to the longitudinal axis. The cutting tooth is set relative to the vertical axis. The plurality of rivets couples the plurality of drive links and the plurality of cutters together.

Abstract: A marker for use in screening patients for nervous system dysfunction and a method of producing the marker. The marker is a digital profile of a brain having a particular nervous system dysfunction that is used for screening patients for that nervous system dysfunction. The digital profile consists of a grid of values that are a numerical representation of graphical images of functional activity in the brain having that nervous systems dysfunction. The marker is produced by selecting a nervous system dysfunction and by creating a digital profile of predetermined functional activity at a plurality of sets of predetermined coordinates of a given brain geometry. The marker can also be used to screen patients for any specific functional brain activity not limited to nervous system dysfunctions.

Abstract: A method and apparatus for screening patients for nervous system dysfunction including neurological capacity and dysfunction. A patient profile of actual functional activity of a brain of a patient is produced and compared with at least one marker. The marker is a profile of predetermined functional activity at a plurality of sets of predetermined coordinates of a given brain geometry.
