  • Patent number: 11171488
    Abstract: A solar power system may include a solar panel set, a lithium battery set, a first controller, and a second controller. A single-contact switch is electrically connected between the solar panel set and the lithium battery set. When the first controller detects that the generated voltage of the solar panel set reaches a preset threshold value, the first controller is adapted to trigger the first awakening of the lithium battery set by electrically conducting the single-contact switch, thereby brought the lithium battery set out of the low potential protection state. Also, when the second controller detects the voltage of the lithium battery set is not rising after the first awakening of the lithium battery set, the first controller is driven by the second controller to process the second awakening of the lithium battery set through the single-contact switch.

    Abstract: A method and apparatus of video coding using history-based candidate derivation are disclosed. According to one method, a current block is inside a Shared Merge candidate list Region (SMR) or a history-based parallel processing region is received. The current block is encoded or decoded using a Merge candidate list. Only if the current block is one of first-coded N (N?0) blocks, one of last-coded N blocks, or one of selected N blocks, the history-based candidate list is updated after the current block is encoded or decoded. In one embodiment, Merge candidate list is pre-generated for the current block in the SMR and is separately generated for the current block in the history-based parallel processing region. In another method, if the current block is inside the SMR or the history-based parallel processing region, the current block is encoded or decoded using a history-based candidate list associated with the root CU.
