Abstract: In detecting a boundary line between areas different in light reflectance, it has so far been impossible to specify the boundary line at a distance shorter than the arrangement pitch of photodetectors (pixels) arranged in the camera. In the present invention, luminance variations near the boundary line between areas different in light reflectance are derivated. Further, in unit blocks G corresponding to pixels and arranged in a direction (Y direction) in which the boundary line extends, derivated values of luminance for each row of unit blocks are added and then a variation curve of the added values of derivated luminance values in unit block rows is drawn to specify a peak position thereof and also specify the position of the boundary line X0. Thus, it is possible to specify the position of the boundary line with a high accuracy at a distance shorter than the unit block pitch.

Abstract: A window is protected from storms by applying a rigid protective panel, such as a plywood sheet cut to size, to the window frame. The panel is held securely in place by one or more innovative elongate braces or bars that extend from one wall of the window opening to an opposed wall. The brace has a long body provided with a planar friction pad at each end. Each pad is angularly adjustable relative to the long axis of the body to conform to the angle of the wall for maximum contact. One of the friction pads is connected to the body by a spring-loaded connection that allows for a short reciprocating motion with the spring urging the pad away from the body. This enables the user to temporarily hold the panel in place with one hand, while pushing the brace in place with both pads engaging opposed walls in a panel holding position with the other hand. The brace is then more tightly and securely extended by advancing a threaded nut that forces the pad farther away from the body.

Abstract: A porous, low-conductivity material formed of metal or ceramic fibers provides the burner face of a gaseous fuel combustor for gas turbines capable of minimizing nitrogen oxides (NOX) emissions in the combustion product gases. A preferred burner face, when fired at atmospheric pressure, yields radiant surface combustion with interspersed areas of blue flame combustion.

By controlling the excess air admixed with the fuel in the range of about 40% to 150% to maintain an adiabatic flame temperature in the range of about 2600° F. to 3300° F., the NOX emissions are suppressed to 5 ppm and even below 2 ppm. At all times, carbon monoxide and unburned hydrocarbons emissions do not exceed 10 ppm, combined.
