    Abstract: A glare reduction system includes a light source, a first circular polarizing filter, and a pair of second circular polarizing filters. The first circular polarizing filter is positioned to receive light from the light source. The first circular polarizing filter is able to pass light that is polarized in a first circular direction. The second circular polarizing filters include respective portions positioned laterally from one other. The pair of second circular polarizing filters is located a distance from the first circular polarizing filter. Each of the pair of second circular polarizing filters is able to pass light that is polarized in a second circular direction. The second circular direction is opposite the first circular direction

    Abstract: A floor cleaning machine includes a housing having a front end and a rear end, and a rotary brush coupled to the housing for rotation with respect to the housing. A collection bin is configured to receive debris from the rotary brush and a debris intake is in fluid communication with the collection bin. A motor rotates the rotary brush, and a power source supplies power to the motor. A suction source is in fluid communication with the collection bin to draw debris into the debris intake and to direct the debris into the collection bin. A projection is positioned adjacent the rotary brush and the debris intake engage bristles of the rotary brush to dislodge debris from the bristles, so that the suction source is configured to draw debris dislodged from the bristles of the rotary brush into the debris intake.

    Abstract: A pipe fitting stand for supporting a pipe during a work operation includes a table, and a plurality of legs coupled to the table and movable between a deployed position and a stowed position. The pipe fitting stand additionally includes a vise coupled to the table for supporting a first portion of the pipe, and a support positioned on a side of the table opposite the vise upon which a second portion of the pipe is supported. The support is adjustable relative to the table, thereby adjusting the orientation of the pipe relative to the table.
