Voice coil actuator direct-drive resonant system

An unmanned aerial vehicle (UAV) equipped with sensor modules and mobile devices (including smartphone, tablet) running intelligent software for autonomous navigation, onboard computer vision, communication, and robotic social networks, is disclosed herein.

Mobile device enabled robotic system

A method controls an angular speed of an induction motor by measuring a stator current and a stator voltage of the induction motor to determine an estimated stator current, an estimated rotor flux amplitude, and an estimated rotor speed. A first virtual control signal is based on a reference rotor speed and the estimated rotor speed. A second virtual control signal is based on the first virtual control signal and an estimated electromagnetic torque. A third virtual control signal is based on a reference rotor flux reference and the estimated rotor flux amplitude. A fourth virtual control signal is based on the third virtual control signal and an estimate of the third virtual control signal. Then, control input voltages are applied to the induction motor based on the second virtual control signal and the fourth virtual control signal.

Method and system for controlling angular rotor speeds of sensorless induction motors

Methods for the detection and screening of esophageal adenocarcinoma (EAC) patients and for the monitoring of EAC treatment using a panel or panels of small molecule metabolite biomarkers are disclosed. In other aspects, methods for detection and screening for the progression of high-risk conditions (BE and HGD) to EAC and to monitoring treatment using a panel or panels of small molecule metabolite biomarkers are disclosed. The biomarkers are sensitive and specific for the detection of EAC, and can also be used to classify Barrett's esophagus (BE) and high-grade dysplasia (HGD), which are widely regarded as precursors of EAC.
