  • Patent number: 10367371
    Abstract: An intelligent charging system comprises a first switching element, a phase detecting device, a current detecting device and a controller. The first switching element is turned on or off based on a first control signal. The phase detecting device is configured to determine an allowable phase time interval of a phase of a power source. The current detecting device is connected to the first switching element. The current detecting device is configured to detect a first turned on time point when the first switching element is turned on. The controller is connected to the phase detecting device and the current detecting device. The controller is configured to determine whether the first turned on time point is within the allowable phase time interval. If the first turned on time point is not within the allowable phase time interval, the controller resets a first control parameter of the first control signal.

  • Patent number: 10186865
    Abstract: An intelligent charging device has a control unit and multiple power strips respectively connected to and simultaneously charging multiple sets of digital devices. Each power strip has a relay connected to the control unit. When acquiring load signals of the power strips and a maximum load threshold, the control unit performs a charging schedule configuration to generate a charging demand sequence, and then calculates a charging time for each charging schedule of a charging cycle according to the charging demand sequence and the load signals of the multiple power strips for charging time allocation and instructs each power strip to charge for a corresponding charging time in a corresponding charging schedule, thereby allowing the power strip with the maximum charging demand to charge first and achieving the goal of efficiency charging.

  • Patent number: 10056768
    Abstract: A charging cabinet and a control method thereof are disclosed. The charging cabinet includes a controller, a power supply, switches, a charging detector, a status detector, and sockets electrically connected to devices. The switches are selectively tuned on to connect a current path between one of the sockets and the power supply. When a current value of the current path is smaller than a preset current value, the charging detector products a first detection signal. The status detector produces a second detection signal after counting up to more than a preset time period, during which the charging cabinet stays at a suspension status. The controller turns on at least part of the switches after counting up to more than an idle time period, during which the switches in the charging cabinet at the suspension status are tuned off according to the first and second detection signals.

  • Patent number: 9608457
    Abstract: A charging device for commonly charging multiple digital electronic devices has a housing, a charge control unit and multiple outlet strips. The charge control unit is mounted inside the housing and has multiple relays. The outlet strips are electrically connected to the charge control unit with each outlet strip electrically connected to one of the relays. A charging method corresponding to the charging device is performed by the charge control unit without the need of users' configuration during a charge cycle. The charge method automatically determines if the outlet strips can simultaneously supply power to charge during each charge schedule of the charge cycle. At least one outlet strip supplies power to charge during each charge schedule, and each outlet strip supplies power to charge once, thereby achieving optimization for the charging process with automatic determination and enhancing charging efficiency and users' operational convenience.

    Abstract: An apparatus and a method for eliminating glare are disclosed, wherein this method includes steps as follow. First, a first image is captured from an object when a first light source radiates light and a second light source is turned off, and a second image is captured from the object when the first light source is turned off and the second light source radiates light, wherein the first and second light sources are separate from each other. Then, a first glaring area is removed from the first image to create a first modified image, and a second glaring area is removed from the second image to create a second modified image. Then, the first and second modified images are merged to create a merged image.
