Abstract: A true color image enhancement system includes an ambient light sensor, a circuit and a processor. The ambient light sensor measures an ambient light level. The circuit generates a histogram based on an input video signal; and generates an output video signal by converting gray shades in the input video signal based on input video luminance ratios and a look up table to determine new output gray shade values to maintain input video color coordinates. The processor develops the look up table based on the histogram and the ambient light level; dynamically remaps the gray shades in the look up table in response to the ambient light signal to compress one region and stretch another region; dynamically remaps the gray shades in the look up table to correct for ambient lighting conditions; and transfers the look up table to the circuit.

Abstract: A dynamic edge enhancement system includes a light sensor, a circuit, and a microcontroller. The light sensor is operational to generate a light background signal by measuring an ambient light falling on a display. The circuit is operational to generate a histogram of gray shade values in multiple frames of an input video signal received by the circuit, detect multiple edges in the input video signal, enhance the multiple edges in response to a gray shade transfer table and an edge mask strength value, and generate an output video signal suitable to drive the display after the enhancement of the edges. The microcontroller is operational to generate the gray shade transfer table based on the histogram generated by the circuit, and generate the edge mask strength value in response to the gray shade transfer table, the light background signal, a night luminance threshold value, and a day luminance threshold value.

Abstract: A tank recirculation assembly comprising a recirculation line that draws fluid from the lower portion of a tank; and a pump that directs the recirculated fluid vertically toward and into the upper portion of the tank. The assembly comprises piping, pumping process and/or nozzles that spray the recirculated fluid across the surface oil inside of the tank. Recirculation is incorporated to enhance the recovery of more and cleaner oil by spraying as much of the surface area of the oil recovery zone to keep it clean. The then dispersed fluid travels down through the pad and reacts to help disperse and remove the interface that conglomerates in between the oil and water interface.
