Latest Patents

One of his latest patents is titled "Cooperative filter and raster operation evaluation model." This invention presents a method and apparatus for handling transparency operatives simultaneously with raster operatives in a graphics environment. The innovation introduces filter operations to achieve the effect of transparency, allowing for cooperative work with grayscale and continuous-tone color raster operations. This solution simplifies a computationally complex problem by utilizing a single hardware circuit for real-time applications, such as monochrome and color laser printing. Additionally, it is applicable for displaying complex graphics on video display devices. The apparatus processes graphics language commands to generate a bitmap image, employing both a raster operation model and a filter operation model to modify the destination effectively.

Another significant patent by Horowitz is the "Method and apparatus for double run-length encoding of binary data." This invention focuses on losslessly compressing binary data using a technique known as Double Run-Length Encoding (DRLE). DRLE is particularly effective for compressing gray-scale data during processing for printing by laser printers or other continuous raster scan devices. The method records repeating patterns of ones and zeros with minimal computational complexity, achieving impressive compression ratios that often exceed traditional Run-Length Encoding (RLE). DRLE utilizes a sequential history of order-pairs to denote variable-length patterns of zeros and ones, encoding these patterns as they repeat.
