  • Publication number: 20250118072
    Abstract: Provides is a method for detecting a complex target in pedestrian re-identification video streams based on an event-related potential (ERP). According to the method, video streams of a complex target in different scenarios are collected, and are made into experimental paradigms, and electroencephalogram (EEG) data of a subject during watching of a video content is collected. Then brain electrical activity mapping (BEAM) is analyzed, and ERP features are marked, including P300 and P300-D, which correspond to target emergence and target disappearance respectively. Positive and negative sample pairs are constructed, and essential features between classes are obtained based on a method of contrastive representation learning and a method of spatial-temporal feature attention extraction, so as to solve the extreme class imbalance problem of samples and the problem of how to distinguish between two similar classes in a video paradigm.

  • Publication number: 20250001174
    Abstract: An electric stimulation method based on inspiration of healthy side lower limb muscle synergy and a system thereof are provided. A motion process of a healthy side limb of an individual is analyzed, and in combination with an electromyographic signal and a motion posture signal, a muscle motion model which is more in line with coordination of an individual's own limb is established, and the healthy side limb muscle motion model is used to guide the affected limb to move. Inspired by the healthy side limb of an individual, the electromyographic signal and the motion posture signal of the healthy side limb are acquired, and the motion model of the healthy side limb is established. The change relationship of the muscle synergy activation degree with the time is mapped as the change relationship of the muscle synergy activation degree with the angle, which eliminates time-varying interference.

  • Patent number: 9943875
    Abstract: A water valve and a drinking device are provided. The water valve includes an upper support, a lower support, a valve spool, a sealing member, a spring and a water outlet. The upper support is provided with a water inlet. The lower support is provided with a water outlet and a vent hole. The valve spool has a first end connected with the upper support and a second end fixedly connected with the lower support, and the valve spool is movable relative to the upper support, to switch on or off a communication between the water inlet and the water outlet. When the water valve is at a state of discharging water, an interior of the water outlet pipe is not communicated with atmosphere; when the water valve is at a state of not discharging water, the vent hole communicates the interior of the water outlet pipe with the atmosphere.
