Latest Patents

David W Long's latest patents include innovations in digitally synthesized gray scale for raster scan oscilloscopes. His first patent describes a gray scale binary field corresponding to each pixel on a raster scan oscilloscope display. Each gray scale binary field has bits assigned to both graphical information and sampled current and prior waveforms. A decrementing state machine periodically reads these fields, decrements their values, and rewrites them back into the display memory. This process allows older waveforms to fade uniformly, enhancing the clarity of the current waveform. The second patent reiterates this concept, emphasizing the importance of minimizing flicker while maintaining the brightness of the most recent waveforms.
