Latest Patents
Chao's latest patents include an "Electronic Torque Realization Apparatus" and an "Absolute Mass Balance." The electronic torque realization apparatus provides torque realization via electrical measurements that are traceable to the revised International Standard of Units (SI). This invention allows for the conversion of a linear mechanism of a Kibble balance to a rotational mechanism. The apparatus features a rotor for holding permanent magnets, a stator for characterizing physical aspects of a torque tool, and a base plate for mounting components. The design also includes a cantilever for supporting the rotor and a bearing assembly for facilitating its motion.
The absolute mass balance is designed to determine the absolute mass of an object. It includes a dual diameter wheel with a balance fulcrum and a balance beam. The system features a main mass receiver, a main magnet system, and a displacement measuring system that provides a null position of the dual diameter wheel. Additionally, it incorporates a driving motor with an eddy current damper to ensure a constant velocity of the main mass receiver.
