Abstract: An apparatus for simulating a vehicle traveling on a road and towing a trailer, wherein the apparatus includes a scale model towing vehicle and trailer combination positioned on a moving belt of a treadmill. The apparatus has a speed control and a remote control steering mechanism to demonstrate how the vehicle/trailer towing combination will react to vehicle operator inputs under varying conditions, including variations in weight distribution of the trailer load.

Abstract: A system for sorting a mixed stream of colors and types of cullet into separate groups of cullet with similar color and type includes a source for transmitting light through a cullet, and a camera having a plurality of pixels for receiving light transmitted through the cullet or detecting the absence of light blocked by an opaque contaminant, the camera providing at least one value from the light received, wherein the cullet moves along a designated path based in part on the at least one value. The system further includes a radiation source for irradiating a cullet with selected spectral ranges of radiation, and a sensor for determining characteristics of one or more selected spectral ranges of fluorescent radiation emitted by the cullet, wherein the cullet moves along a designated path based in part on the characteristics of the one or more selected spectral ranges of fluorescent radiation.
