Title: Innovations by Paulo Irulegui Gomes

Introduction

Paulo Irulegui Gomes is an accomplished inventor based in Redwood City, CA. He holds a total of four patents, showcasing his expertise in the field of acoustic touchscreens. His innovative contributions have significantly advanced touchscreen technology, making it more efficient and user-friendly.

Latest Patents

One of his latest patents is for an acoustic touchscreen having waveguided reflector arrays. This invention features transmitting transducers that generate acoustic signals, which are deflected across a touch-sensitive area by an array of partially acoustically reflective elements. When a user touches the touch-sensitive area, it causes a perturbation in the acoustic signals. The signals are redirected by another array of reflective elements towards receiving transducers, where the signals and any perturbations are sensed. This design accommodates touchscreens with narrow border regions by using acoustic waveguides to confine the signals to a narrow path while allowing deflection across the touch-sensitive area.

Another significant patent is the adaptive frequency touchscreen controller employing digital signal processing. This method and apparatus adapt an acoustic touchscreen controller to the specific operating frequency requirements of a touchscreen. The adaptive controller can utilize look-up tables or a multi-step process to determine and adjust the frequency characteristics of the touchscreen. In one embodiment, it compensates for global frequency mismatch errors using a digital multiplier to modify the output of a crystal reference oscillator. The controller can also be miniaturized to be mounted directly on a touchscreen substrate, enhancing its practicality.
