Patent number: 10618522Abstract: An in-vehicle monitoring and intervention system for detecting whether a driver in a vehicle is drowsy by monitoring a plurality of physiological signals of the driver is provided. The in-vehicle monitoring and intervention system includes at least a processor and an apparatus, the apparatus can be integrated into a seat belt or attached thereto as a discrete hardware apparatus, which includes at least an ECG sensor, a respiratory sensor, an acceleration sensor, a filtering system, and an intervention module. The filtering system further comprises one or more filters for suppressing noise and reducing motion artifacts. The processor is configured to compare the detected physiological signals with the signals stored in a learning module of the in-vehicle monitoring and intervention system for determining the drowsiness state. If the driver is determined to be drowsy, a warning signal is outputted to alert the driver.Type: GrantFiled: March 22, 2019Date of Patent: April 14, 2020Assignee: Hong Kong Productivity Council (HKPC)Inventors: Yin Bo Liu, Chi Hang Louie, Man Kit Bryan So, Tin Yan Chan, Wu Ming Lai, Ka Yin Leung, Yuk Sum Wong

Patent number: 8253393Abstract: The present disclosure related to a method and a controller for controlling an AC generator which is used in connection with a wind turbine having a variable speed. The multi-phase generator is connected to a controllable converter and is controlled to provide a desired power or a desired torque. An AC reference signal is generated, which would provide the desired power or torque. A P+Resonant converter may be used to control an electrical characteristic of the generator in view of the reference, by applying control signals to the controllable converter. Thereby, the need to transform the electrical characteristic into a rotating frame may be eliminated which provides for a less complex controller.Type: GrantFiled: August 28, 2009Date of Patent: August 28, 2012Assignee: Vestas Wind Systems A/SInventors: Yin Bo, Heng Deng, Kim B.
