With a total of five patents to his name, Chadbourne's work addresses pressing technical challenges, particularly in audio jack functionalities.

Latest Patents

One of his latest patents focuses on "Audio jack insertion/removal fault detection." This document elaborates on circuits and methods designed to indicate the impedance between a detecting pin and a first signal pin of an audio socket. Using first and second comparators, this innovation determines the presence of moisture within the audio socket, thereby disabling communication between the audio processing unit and the audio socket if moisture is detected.

Moreover, Chadbourne has developed a detection circuit for "Detecting accessories on an audio or video jack." This circuit is engineered to receive a digital value from an identification register, evaluating the resistance at a conducting terminal of the audio or video jack plug. The detection circuit includes a current source that outputs a current based on the received digital value, complemented by a comparator that compares a reference voltage to the voltage produced across the resistance at the terminal. This system also features control logic designed to store digital values and manage the identification of accessory functions.
