  • Patent number: 10878747
    Abstract: Methods and systems for compensating a display of an electronic device using internal sensing and external compensation.

  • Patent number: 10795322
    Abstract: With regard to a learning method for a smartwatch to prevent a metal hand from lightening the screen by unintended touch, a mainboard chip firstly finds and learns points which unintendedly touch the screen. Then, the mainboard chip reserves the time Tm which leads to unintended touch on the screen. The mainboard chip judges the present state: at the reserved time Tm, if the display screen is in an ON state, the display screen will keep the ON state. If the display screen is in an OFF state, the display screen will keep the OFF state.

  • Publication number: 20200234170
    Abstract: A method for classifying eco-geological environment types based on coal resource exploitation solves the problem in the prior art of a lack of combined consideration of different geological and ecological environments on the surface in a to-be-mined area before coal mining. Based on surveys of ecological, hydrological, and geological information of the area, and by means of a Fuzzy Delphi Analytic Hierarchy Process (FDAHP) and weighted fuzzy C-means clustering, the present invention determines different eco-geological environment types. According to the existing ecological, hydrological, and geological information, the present invention can rapidly and effectively classify the different eco-geological environment types, and further determine eco-geological features and their sensitivity to coal resource exploitation.

    Abstract: A scalable universal space vector pulse-width modulation (SVPWM) scheme for multilevel inverters is disclosed. In the disclosed SVPWM scheme, the modulation triangle is quickly identified based on a coordinate transformation from an ?-? coordinate system to a 120° oblique coordinate system. Then, the duty cycles and switching states of the three vertices of the modulation triangle are determined by simple algebraic computations. In a switching period, any vertex of the modulation triangle can be flexibly selected as the start point to optimize the switching sequence with flexibly adjustable duty cycle(s) for the redundant switching state(s) according to specific applications.
