20160028343 | FAULT TOLERANT CONTROL SYSTEM FOR MULTI-PHASE PERMANENT MAGNET ASSISTED SYNCHRONOUS RELUCTANCE MOTORS - A fault tolerant control system for a multi-phase permanent magnet assisted synchronous reluctance motor utilizes vector control to provide safe operation under various phase loss fault conditions. Specifically, the vector control of the present invention utilizes a fault tolerant algorithm that receives a torque input and an electrical current feedback signal from the motor. Thus, in the presence of a fault condition, the vector control applies the optimal torque angle to the motor, while reducing the phase currents to an optimized value to lessen the saturation effect in the motor, so as to ensure that the motor delivers maximum torque output in the presence of such faults. As such, the control system allows the motor to operate safely with high reliability, which is highly desirable, such as in electric vehicles and the aerospace industry. | 01-28-2016 |

20130153497 | VACUUM MEMBRANE DISTILLATION (VMD) USING ASPIRATOR TO GENERATE VACUUM PRESSURE - A VMD system and method uses an aspirator to generate a vacuum pressure for drawing permeate from a membrane module. The aspirator generates the vacuum pressure by receiving and passing a circulating liquid and combines the permeate with the circulating liquid such that the permeate condensates in the circulating liquid. Using an aspirator (e.g., instead of a vacuum pump) allows a more efficient and cost-effective operation of the VMD system and method, particularly in a desalination application. A VMD system and method using an aspirator may be used in desalination and other applications including, without limitation, environmental cleanup (e.g., removal of volatile organic chemicals from water) and food and medical applications. | 06-20-2013 |
