Latest Patents

One of Skillman's latest patents is a method of reducing electromagnetic emissions (EMI) from LED bar systems. This invention addresses the challenges posed by high-frequency clocks and data in LED systems, which can lead to EMI problems. By employing a spread spectrum technique, Skillman’s method distributes EMI energy over a range of frequencies, effectively reducing peak EMI amplitudes. This approach is particularly relevant as the U.S. federal government imposes stricter regulations on EMI emissions.

Another significant patent is the Direct Digital Synthesis pixel clock generator, designed for use in electrophotographic printers. This innovative device utilizes a controller that responds to a start-of-scan signal and a facet 0 signal. The controller sends a pre-stored frequency control word to a Direct Digital Synthesis Oscillator, which generates pulses at a frequency determined by the control word. The system includes a Digital Phase Shift Circuit that adjusts the position of scan line pixels, ensuring precise synchronization with the start-of-scan signals.
