| 20090150582 | Hardware assisted endpoint idleness detection for USB host controllers - In some embodiments, an electronic apparatus comprises at least one memory module, and a universal serial bus (USB) host controller coupled to the memory, wherein the USB host controller implements hardware assisted idleness endpoint detection. | 06-11-2009 |
| 20090216981 | POWER EFFICIENT FLOW CONTROL MODEL FOR USB ASYNCHRONOUS TRANSFERS - Embodiments comprising a memory and a USB host controller coupled to the memory. The power efficiency of a USB during asynchronous transfers is increased by limiting usage of an asynchronous schedule stored in the memory when servicing a scheduled asynchronous transfer endpoint. Other embodiments may be described and claimed. | 08-27-2009 |
| 20100083013 | Various Methods and Apparatuses for Power States in a Controller - Various methods, apparatuses, and systems are described in which a chipset controller has circuitry to control communications with a peripheral device in a computing device. The chipset controller has logic configured 1) to detect a plug-in event when the peripheral device connects to the chipset controller and 2) to transition the chipset controller from a low power consumption state to a higher power consumption state based on the logic detecting the plug-in event. | 04-01-2010 |
| 20110078344 | HARDWARE ASSISTED ENDPOINT IDLENESS DETECTION FOR USB HOST CONTROLLERS - In some embodiments, an electronic apparatus comprises at least one memory module, and a universal serial bus (USB) host controller coupled to the memory, wherein the USB host controller implements hardware assisted idleness endpoint detection. | 03-31-2011 |
| 20110078475 | Transitioning a Computing Platform to a Low Power System State - A method which includes initiating a power management policy based on a processing element for a computing platform entering a given power state. The power management policy includes a determination as to whether an input/output (I/O) controller and a memory controller for the computing platform are substantially quiescent. The computing platform may then be transitioned to a low power system state from a run power system state based on a determination that both the I/O controller and the memory controller are substantially quiescent and an indication that the computing platform is capable of entering the low power system state. According to this method, the low power system state includes entering one or more devices responsive to the computing platform in a power level adequate to retain a configuration state that enables the one or more devices to transition back to the run power system state in a manner that is substantially transparent to an operating system for the computing platform. Other implementations and examples are also described in this disclosure. | 03-31-2011 |

| 20090249103 | PLATFORM POWER MANAGEMENT BASED ON LATENCY GUIDANCE - Embodiments of a system for receiving power management guidelines from a first plurality of components of a system, and developing a power management policy to manage one or more of a second plurality of components of the system based at least in part on the received power management guidelines. Other embodiments are described. | 10-01-2009 |
| 20110096048 | DISPLAY BRIGHTNESS ADJUSTMENT - Embodiments of the present invention can receive a data point defining an ambient light level associated with a display and a corresponding brightness adjustment of the display with respect to a reference brightness. The embodiments can then define a brightness response model for the display based on the data point and at least one additional data point. | 04-28-2011 |
| 20110157198 | Techniques for aligning frame data - Techniques are described that can used to synchronize the start of frames from multiple sources so that when a display is to output a frame to a next source, boundaries of current and next source are aligned. Techniques are useful to avoid visual distortions when changing from a first video source to a second video source. | 06-30-2011 |
| 20110157202 | Techniques for aligning frame data - Techniques are described that can used to synchronize the start of frames from multiple sources so that when a display is to output a frame to a next source, boundaries of current and next source are aligned. Techniques attempt to avoid visible glitches when switching from displaying a frame from a first source to displaying frames from a second source even though alignment is achieved by switching if frames that are to be displayed from the second source are similar to those displayed from the first source. | 06-30-2011 |
