Abstract: A network switch having a plurality of ports may be configured with a plurality of wake domains, which may be independently transitioned between at least a wake state and a sleep state. For example, one or more wake domains may transition between a wake state and a sleep state while one or more other wake domains do not change state. The ports included in each of the wake domains may be dynamically configurable. In this way, power may be conserved by operating a subset of the plurality of ports in the wake state, while other ports remain in the sleep state. In some embodiments, the wake domains may be prioritized, such that, upon a simultaneous command, a higher-priority wake domain may be awakened before a lower-priority wake domain. In this way, high-priority ports may be awakened in less time than would be required to awaken the entire network switch.

Abstract: The disclosed embodiments relate to a system that provides power for a touch-enabled display, wherein the touch-enabled display cycles between a display mode and a touch mode. During the display mode, the system drives a display-mode voltage to the touch-enabled display through a power output, wherein the power output is coupled through a display-mode capacitor CD to ground. Next, during a transition from the display mode to the touch mode, the system couples the power output through a touch-mode capacitor CT to ground, wherein CT was previously charged to a touch-mode voltage, which causes the power output to rapidly transition to the touch-mode voltage. Then, during the touch mode, the system drives the touch-mode voltage through the power output.
