Title: Innovations of Xiaoqi Bao: Pioneering Ultrasonic Technologies

Introduction

Xiaoqi Bao, based in San Gabriel, CA, is an accomplished inventor with a remarkable portfolio of 22 patents. His innovative contributions primarily focus on advancing ultrasonic and sonic actuator technologies, which have far-reaching applications in various industries.

Latest Patents

Among his latest innovations is the "Dual frequency ultrasonic and sonic actuator with constrained impact mass." This invention features a distinctive design where the displacement of the impact mass is constrained by a cavity, a spring, or a flexure, allowing for the conversion of ultrasonic stress into lower frequency sonic stress. The sonic stress can then be coupled to different transmitting elements, such as a longitudinal probe, a drill bit, or a thumper, facilitating the transmission of elastic waves through surfaces.

Another significant patent is the "Multi-stack piezo actuator." This technology incorporates increased radiating surfaces provided by multiple piezoelectric stacks, each compressed by a bolt against a common backing structure. The design aims for amplitude uniformity of displacement, enhancing the actuator's efficiency. The radiating surface is symmetrically shaped, allowing for optimal performance within specified operational wavelengths.
