Abstract: In one embodiment of the invention, an integrated device is described that employs a mechanism to control power consumption of a graphics memory controller hub (GMCH) through both voltage and frequency adjustment of clock signal received from a clock generator. The GMCH comprises a graphics core and a circuit to alter operational behavior, such as the frequency of a render clock signal supplied to the graphics core. The circuit is adapted to monitor idleness of the graphics core and reduce a frequency level of the render clock signal if the idleness exceeds a determined percentage of time.

Abstract: A down-hole well tool is disclosed for removing debris from a well utilizing low pressure/suction. More particularly, the tool is adapted to generate the low pressure within a well bore for removing debris while being interconnectable to the end of a single duct tubing that extends to the surface. Use of the low pressure/suction allows removal of debris without of forcing such debris into the permeable formations of the well. In one application, the tool may be utilized during open-hole completion processes. In another application, the tool may be utilized to clean existing wells.

Abstract: Methods and devices for power management of graphics or other computer subsystems are disclosed. In one embodiment, graphics software components are configurable in a manner that allows them to place the graphics subsystem is a “safe” state prior to a suspend event, and back into a “working” state after a resume event, without explicit support from an operating system (OS) power management driver. When operating in the absence of an OS-supplied driver, the graphics driver receives notification of power management events, and sends a message to a support application, which then causes the graphics to enter a quiescent state by taking exclusive ownership of the display and issuing standard device-independent OS graphics calls (for a power-down event) or to relinquish display ownership (for a power-up event). From within this quiescent state the graphics may be safely power managed without adverse effects to the graphics chips and without creating any instabilities in other graphics applications.
