Abstract: A digital display of an active window is provided. An application, separate from the application providing the digital display, is capable of identifying an artifact in the active window of the digital display without a priori knowledge or an application programming interface to the application providing the digital display. The artifacts may be alpha-numeric artifacts or non-alpha-numeric artifacts. The active window may be examined in multiple dimensions including 2 dimensions, 3 dimensions or more. Alpha-numeric artifacts, once identified, are pre-processed to remove anti-aliasing to allow for processor optical recognition.

Abstract: A reinforced liner for cured in place pipe rehabilitation of an existing pipeline having a plurality of high-strength low-elongation fiber bundles disposed circumferentially around the tubular liner at both inner and outer surfaces of a resin absorbent layer of the liner is provided. The bundles of reinforcing fibers are continuous lengths of high modulus fibers laid circumferentially with the ability to stretch to accommodate variations in host pipe diameter. The ends of reinforcing fibers on the inner and outer reinforcing layers overlap so that the ends slide past each other as the liner is expanded prior to cure. The reinforcing fibers may be secured to a porous scrim to form an inner tubular reinforcing layer. An outer layer of bundles of reinforcing fiber are formed into a tube about the absorbent layer. An outer impermeable tubular layer is wrapped around the inner layers.

The reinforcing layer may include longitudinal reinforcing fiber in either or both reinforcing layers to increase the longitudinal strength of the liner.

Abstract: A longitudinally reinforced liner for cured in place pipe rehabilitation of an existing pipeline having a plurality of high-strength low-elongation fiber bundles disposed between resin impregnable layers of the liner is provided. The bundles of reinforcing fibers are continuous lengths of reinforcing fibers laid out adjacent to each other and parallel onto about one-half of the middle region of the upper surface of the outer resin impregnable layer. An inner resin impregnable layer formed into a tube is laid up against the outer layer and the reinforcing fiber bundles and a plurality of bundles of reinforcing fibers are laid out along the exposed surface of the flattened inner layer. The edges of the outer layer are wrapped around the inner layer and bundles of reinforcing fibers and the secured to form an outer tubular layer with the reinforcing strands remaining in position between the two layers.
