  • Patent number: 11928473
    Abstract: An instruction scheduling method and an instruction scheduling system for a reconfigurable array processor. The method includes: determining whether a fan-out of a vertex in a data flow graph (DFG) is less than an actual interconnection number of a processing unit in a reconfigurable array; establishing a corresponding relationship between the vertex and a correlation operator of the processing unit; introducing a register to a directed edge, acquiring a retiming value of each vertex; arranging instructions in such a manner that retiming values of the instruction vertexes are in ascending order, and acquiring transmission time and scheduling order of the instructions; folding the DFG, placing an instruction to an instruction vertex; inserting a register and acquiring a current DFG; and acquiring a common maximum subset of the current DFG and the reconfigurable array by a maximum clique algorithm, and distributing the instructions.

  • Publication number: 20230396097
    Abstract: A wireless power transmitting device includes a surface adapted to support a container containing a wireless power receiving device and further includes a wireless power transfer coil positioned to couple with a wireless power receiving coil of the wireless power receiving device when the container is placed on the surface. The wireless power transmitting device detects a presence of the wireless power receiving device when the container containing the wireless power receiving device is placed on the surface and determines whether the wireless power receiving device permits wireless power transfer while it is inside the container. Using the wireless power transfer coil, the wireless power transmitting device wirelessly transmits power to the wireless power receiving device through the container to charge a battery of the wireless power receiving device, in accordance with determining the wireless power receiving device permits wireless power transfer while it is inside the container.

  • Publication number: 20220000327
    Abstract: A cleaning robot and an automatic cleaning method thereof, to implement automatic cleaning. The cleaning robot includes a lifting mechanism and a cleaning base, where the cleaning base includes a base body, a scraping mechanism disposed on the base body, and a spraying assembly provided with nozzles. The nozzles are arranged along a mopping component of the cleaning robot and formed into a structure for spraying water or mist to the mopping component. The scraping mechanism includes a scraper, and the scraper comes into contact with and moves relative to the mopping component, to scrape off the attachment on the mopping component while squeezing out the water. The lifting mechanism causes the mopping component to lift or move down by causing the mopping component to come into contact with or separate from the scraper.
