Latest Patents
Among his most recent innovations is the "Time Multiplexed Image Data Decompression Circuit." This advanced circuit is designed to improve the efficiency of color image printing. It accomplishes this by utilizing a compressor to divide each separation image into 8-line strips, independently compressing each strip. The system employs a single decompressor to handle multiple color image separations, decompressing them strip by strip and interleaving them for application to different print heads, each designated for a specific color separation. Notably, Direct Memory Access (DMA) from the main memory facilitates the process of applying the separations to the decompressor. The output from the decompressor is then demultiplexed into distinct print heads, allowing for simultaneous operation of color separations in a single-pass color printer. The innovation includes multiplexing logic that controls the DMA input and the output to separate buffers for each color separation. Additionally, it uses page and line synchronization from each print head to ensure accurate access to the appropriate image raster from the output buffers.
