Abstract: A method is described for controlling an electric motor having a rotor. The method is carried out after a shutdown of the motor has been initiated. The method includes starting a timer in a motor controller, performing regenerative braking to recapture kinetic energy from the rotor as electrical energy, and using the recaptured electrical energy from the regenerative braking to power the motor controller. If the timer in the motor controller exceeds a predetermined timer value, a flag is set in memory in the motor controller to indicate that the motor has stopped.

Abstract: A resource allocation method for network slicing and an orchestrator, comprising: uniformly incorporating resources originally bundled statically with the base station into a dynamic resource pool; allocating, by an orchestrator, resources from among the dynamic resource pool for the network slicing based on different network slicing requirements. A static corresponding/mapping relationship between the hardware/radio resources and the base station is broken, such that hardware/radio resources (e.g., radio access network Virtual Network Function (RAN VNF), baseband unit (BBU), RRH (Remote Radio Head) as well as antenna) that originally corresponded to different base stations will be organized as an integrated and dynamic hardware/radio resource pool and reported to the orchestrator, such that the orchestrator will centrally manage all hardware/radio resources in this pool and then sufficiently utilize and dynamically orchestrate these hardware/radio resources based different needs from the network slicing.

Abstract: Described herein are techniques for removing control of a display from an operating system. The disclosed techniques decouple operation of the physical display device from control of the operating system so that the display device may be powered down while not needed during streaming. The device driver for the graphics card, into which a display device cable is plugged, simulates operation of the display but allows the display to be powered down. Simulating the display involves properly responding to queries or commands from the operating system, and generating the signals that would be expected from the display device by the operating system. While simulated in this manner, whether the display device is actually powered down does not matter to the operation of an application being streamed, because the operating system still “believes” the display device is powered on. Thus application streaming is not interrupted by powering down the display device.
