With a total of 5 patents to his name, Ellis continues to push the boundaries of innovation.

Latest Patents

One of his latest patents is the "Non-predictive tone-coded-squelch frequency determination method." This invention involves a method for scanning multiple radio frequency channels in a receiver to determine the presence of a standard tone-coded squelch frequency. The process includes calculating a mathematical average of subaudible tone samples and filtering out outlying samples. If a sufficient number of samples remain, a predictive tone-coded squelch detector is employed to monitor for the nearest standard tone-coded squelch frequency.

Another significant patent is the "Method for multiplex driving a passive liquid crystal display (LCD)." This method generates bi-level waveforms on the ROW/common lines and COLUMN/segment lines of a passive multiplexed LCD. The invention utilizes binary data from display memory to drive the LCD, incrementing a counter to produce the necessary waveforms for display operation.
