  • METHOD AND APPARATUS FOR DETECTING RELATIVE LOCATION BETWEEN DEVICES
    Publication number: 20240094330
    Abstract: A method and an apparatus for detecting a relative location between devices is disclosed. The detection method includes: obtaining a first target audio signal obtained by a first microphone of a device B; determining a first audio segment and a second audio segment based on a first target moment and the first target audio signal, where the first target moment is a moment determined in the first target audio signal based on a target amplitude; separately searching for the first audio segment and the second audio segment to obtain a first arrival moment and a second arrival moment; and determining a relative location between a device A and the device B based on the first arrival moment and the second arrival moment.

  • Smart outlet system with fast frequency tracking for power system frequency control using distributed appliances
    Patent number: 11114893
    Abstract: Systems and methods are disclosed to control the power grid frequency by capturing the frequency change using an extended Kalman filter method with the distributed smart outlet devices at the low-voltage distribution level; and locally control the relay that provides power to the appliance by comparing the captured frequency with the threshold sent from the cloud control center.
