  • Patent number: 11313599
    Abstract: A refrigerator cooling system, comprising a pipe forming a loop and, sequentially provided on the pipe, a compressor, a condenser, a refrigerant amount regulator, a capillary tube, and an evaporator. The refrigerant amount regulator comprises a storage device and an adjustor provided within the storage device. The storage device is provided therein with a storage cavity for holding a refrigerant. The storage device is provided with an opening for the storage cavity to be in communication with the pipe. The adjustor comprises a sealer used for opening or closing the opening.

  • Publication number: 20210224119
    Abstract: Adjusting an operating frequency of a CPU includes setting the operating frequency for a current operating cycle based on a CPU load in a prior operating cycle and a target CPU load. A current CPU load associated with the current processing cycle is detected. The CPU operating frequency is adjusted to a new operating frequency based on a difference between the target CPU load and the current CPU load. The operating frequency is adjusted based on minimizing the difference between the target CPU load and the detected load. A CPU load error is determined based on the current CPU load and the target CPU load. The target CPU load is adjusted based on the determined CPU load error and a threshold load error. A prediction is generated on whether to perform a new adjustment of the operating frequency of the CPU prior to expiration of a threshold time duration.

  • Patent number: 10257090
    Abstract: A computer-implemented method classifies a packet received from a network. The method comprises receiving the packet having header information and a rule-set that indicates a plurality of actions to perform on the packet. A geometric representation of the rule-set is constructed having a plurality of dimensions and rule boundaries. At least one rule boundary and dimension of the geometric representation is split to form a search structure having a plurality of nodes. Each node in the plurality of nodes is constrained to a predetermined memory threshold. The search structure is searched using the header information to obtain a rule in the rule-set that indicates an action to take on the packet.
