Title: The Innovative Contributions of Joseph V Chatigny
Introduction
Joseph V Chatigny is a notable inventor based in Wayne, Pennsylvania, who has made significant contributions to the field of technology through his innovative patents. With a total of four patents to his name, Chatigny has focused on developing advanced solutions that enhance functionality and efficiency in various applications.
Latest Patents
One of his latest inventions is the "Reflective Mode Ultrasonic Touch Sensitive Switch." This innovative touch-sensitive switch is designed using a substrate that features a touch region on one surface and a piezoelectric element on the opposite surface. The piezoelectric element generates ultrasonic waves that are transmitted into the substrate, reflecting back and forth. A touch alters the reflectivity at the first surface, impacting the impedance of the transducer assembly, which consists of the piezoelectric element and the substrate.
Another significant patent is the "Traffic Sensor Having Piezoelectric Sensors Which Distinguish Lanes." This traffic sensor utilizes piezoelectric sensors with varying polarities across different lanes of a roadway. This design allows for the discrimination of traffic data from multiple lanes based on the polarity of the received signals. By employing unique combinations of output polarities, the invention can differentiate traffic data from up to eight lanes using only two piezoelectric sensors, simplifying installation by allowing the sensors to be housed in parallel or concentrically within the same cable.
