  • Publication number: 20200412167
    Abstract: The disclosure provides a method for fast reconfiguration of power supply grid in tens of milliseconds after power grid failure. The master station of fast reconfiguration of power grid concentrates the network status information from the client stations at transformer substations or power plants, and compares it with the built-in control strategy table which deals with possible faults. When an expected power gird disconnection fault is detected, the pre-start switch-on instruction is sent to the client stations with multiple breakers which can reconnect the grid. When the fault is cleared, the client stations shall identify the fault clearing time according to the local information, and send the instruction of synchronous switch-on to the corresponding local breakers which can reconnect the separated grids.

  • Publication number: 20200344754
    Abstract: Disclosed herein are related to a system and a method of remotely rendering artificial realty. In one approach, a console determines an expected transmission end time of a first session for wireless transmission of image data indicating an image of artificial reality to a head wearable display. In one approach, the console determines an expected process end time of generating additional data associated with the image of the artificial reality. In one approach, the console compares the expected transmission end time and the expected process end time. The console may transmit, to the head wearable display in the first session, the additional data together with the image data, in response to the expected process end time being less than the expected transmission end time.
