To achieve adaptive control, fault diagnostics, sampled data of machine performance and tool wear, modern machine tools require reliable sensing of one or more of six force components (x,y,z,torque, a&b moments) acting on the tool. present force sensing method either have insufficient resolution… More

Present thrust sensing methods on rocket engine ground test stands either have insufficient resolution and time response, are costly to install, calibrate and replace or result in \require significant added structural complaince. a revolutionary method of accurately sensing small forces applied to… More

The audio mechanical transducer (amt) communication system will significantly improve the environment of workers in high-ambient-noise conditions by providing a new method of communicating. the system will attach directly to most forms of hearing protection without modification of the protector. it… More
