ALEXANDRIA, Va., Dec. 2 -- United States Patent no. 12,487,706, issued on Dec. 2.
"ADC data processing circuit for touch controllers" was invented by Tong Tee Tan (Singapore).
According to the abstract* released by the U.S. Patent & Trademark Office: "According to an embodiment, a signal processing circuit includes a coefficient accumulator and dual multiplexer paths for handling invalid ADC samples in touch controllers. When ADC samples exceed a saturation threshold, the circuit selects zero values through one multiplexer while accumulating coefficients through another multiplexer path. Upon receiving a first valid sample, the circuit multiplies it with accumulated coefficients before resuming normal coefficient processing. The architect...
