  • Publication number: 20250247260
    Abstract: Devices, systems, methods, and processes for transmitting power and managing power transmission are described herein. A device may be configured to transmit power to multiple user devices. The device can receive, from a licensing server, a power utilization license indicative of a power consumption threshold. The device can transmit power to the user devices based on the power utilization license. The device may monitor a power consumption of the user devices. The device can identify a license gap based on a difference in measured power consumption of the user devices and the power consumption threshold. The device may transmit a signed utilization signal indicative of the measured power consumption and the license gap. The licensing server can provide a temporary power utilization license by way of a synchronization response signal. The device can thereby transmit power to the one or more user devices based on the temporary power utilization license.

  • Patent number: 10801726
    Abstract: The present disclosure is directed to a combustor assembly for a gas turbine engine. The combustor assembly includes a deflector wall, an annular axial wall, and an annular shroud. The deflector wall is extended at least partially along a radial direction and a circumferential direction relative to an axial centerline and adjacent to a combustion chamber. A fuel nozzle opening is defined through the deflector wall, and a nozzle centerline is extended through the fuel nozzle opening along a lengthwise direction. The annular axial wall is coupled to the deflector wall and extended through the fuel nozzle opening. The axial wall is defined around the nozzle centerline. The annular shroud is defined around the nozzle centerline and extended co-directional to the axial wall. The axial wall and the annular shroud are each coupled to a radial wall defined upstream of the deflector wall. The annular shroud, the axial wall, and the radial wall together define a cooling plenum therebetween.

  • Patent number: 8423674
    Abstract: A method and apparatus for process sync restart is described. A computer implemented method comprises receiving a first set of data from a network process, determining death of the network process, clearing the first set of data if a time period expires, and synchronizing the first set of data with a second set of data if the time period does not expire, the second set of data received from the network process after the network process restarts.
