A Lower Limb Powered Orthosis for Improved Rehabilitation Training
Physical training is often needed for patients to relearn how to walk after a stroke, or other neurological damage. However, the frequency and availability of physical training are limited by finite medical resources: most lower-limb rehabilitation orthoses are stationary and only available in a limited number of clinical settings, due to their large...

Virtual Body-Weight Support via Lower-Limb Exoskeleton
Summary:This is a novel control system for powered lower-limb exoskeletons (or orthoses) that provides body-weight support (BWS) for people who have sustained a stroke and other neurological injury. Patients are provided with BWS during conventional gait retraining to help them produce the coordinated muscle activities needed for walking. Although current...

High Torque Density Switched Reluctance Motors
Applications like aerospace, automotive and robotics require high torque to volume/weight ratio machines. Permanent Magnet Machines have been considered to be the sole candidates, however, the limitation of the operational temperature, relatively high price, and unstable overseas supply of permanent magnet material limits its massive applications. There...
