Patent number: 11783601Abstract: A driver fatigue detection method based on combining a pseudo-three-dimensional (P3D) convolutional neural network (CNN) and an attention mechanism includes: 1) extracting a frame sequence from a video of a driver and processing the frame sequence; 2) performing spatiotemporal feature learning through a P3D convolution module; 3) constructing a P3D-Attention module, and applying attention on channels and a feature map through the attention mechanism; and 4) replacing a 3D global average pooling layer with a 2D global average pooling layer to obtain more expressive features, and performing a classification through a Softmax classification layer. By analyzing the yawning behavior, blinking and head characteristic movements, the yawning behavior is well distinguished from the talking behavior, and it is possible to effectively distinguish between the three states of alert state, low vigilant state and drowsy state, thus improving the predictive performance of fatigue driving behaviors.Type: GrantFiled: August 18, 2020Date of Patent: October 10, 2023Assignee: Nanjing University of Science and TechnologyInventors: Yong Qi, Yuan Zhuang

Patent number: 11239746Abstract: A two-stage converter, a method for starting the two-stage converter, an LLC converter, and an application system are provided. A controller of the LLC converter of the two-stage converter first controls a main circuit of the LLC converter to perform hiccup charging on a direct current bus of a later-stage converter at a preset interval, so that the direct current bus voltage of the later-stage converter gradually increases, until an auxiliary power supply of the later-stage converter starts to operate, to supply power to the controller of the later-stage converter. After the controller of the later-stage converter reports the detected direct current bus voltage, the controller of the LLC converter determines whether the output voltage of the LLC converter increases to a hiccup starting voltage. If so, the controller of the LLC converter controls the main circuit to operate in a hiccup voltage stabilization phase.Type: GrantFiled: February 6, 2020Date of Patent: February 1, 2022Assignee: Sungrow Power Supply Co.
