  • Publication number: 20220209973
    Abstract: The present invention discloses a power supply method having power management mechanism that includes the steps outlined below. Power request information of power requesting devices is retrieved to generate a to-be-powered device list and a requested power. Whether a current requesting device satisfy a power stable criteria and a power sufficient criteria is determined, The power stable criteria is satisfied when the power requesting devices each having a priority higher than that of the current requesting device all operate in a powered mode or when the power requesting devices that operate in the powered mode enter a stable operation status. The power sufficient criteria is satisfied when a stable system remained power of a power supply system is not smaller than an individual requested power of the current requesting device. When the criteria are satisfied, the current requesting device is operated in the powered mode to update the requested power.

  • Patent number: 10432468
    Abstract: In one embodiment, a method includes receiving an indication of an occurrence of a triggering event for one or more notifications relevant to one or more users. The notifications are sent to one or more of the users through one or more of a number of notifications channels, and each notification channel is associated with one or more software applications. The method also includes accessing a number of notification policies associated with the software applications. Each of the software applications has at least one associated notification policy. At least one of the notification policies associated with a first one of the software applications is interrelated with at least one other notification policy associated with a second one of the software applications. The method also includes sending one or more notifications to one or more users through one or more of the number of notification channels.
