  • Patent number: 11942867
    Abstract: A method of controlling a multi-phase power converter having a plurality of power stage circuits coupled in parallel, can include: obtaining a load current of the multi-phase power converter; enabling corresponding power stage circuits to operate in accordance with the load current, such that a switching frequency is maintained within a predetermined range when the load current changes; and controlling the power stage circuits to operate under different modes in accordance with the load current, such that the switching frequency is maintained within the predetermined range when the load current changes.

  • Publication number: 20230403235
    Abstract: Load aware load balancing may be provided. Flow duration data associated with a plurality of flows associated with a plurality of servers may be obtained. Then a plurality of queue lengths respectively associated with the plurality of servers may be obtained. Next, a Shortest Expected Delay (SED) score may be determined for each of the plurality of servers based on the flow duration data and the plurality of queue lengths. A flow may then be assigned to a one of the plurality of servers having the lowest SED score.

  • Patent number: 10849087
    Abstract: Systems and methods are provided for implementing a coexistence coordinator in an access point (AP) operating in a Internet of Things (IoT) network. The coexistence coordinator coordinates transmission of both IoT-related data from an IoT radio and WiFi data from a WiFi radio, the IoT radio and the WiFi radio coexisting in the AP. The coexistence coordinator synchronizes time between the WiFi radio and the IoT radio so that times during which IoT-related data is to be sent from the IoT radio (in accordance with Time-Division Multiple Access (TDMA) channel access method) can be determined. Operation of the WiFi radio is suspended during those times when the IoT-related data is transmitted from the IoT radio.
