Abstract: Method and apparatus of the present invention include an image-capturing device coupled to a computer system. An image captured by the image-capturing device is analyzed using a face tracking technique to learn behaviors of the user. This may include determining if the user is paying attention. The attention may be toward a display of the computer system. When the user does not pay attention, power consumption of one or more components of the computer system is reduced.

Abstract: Method and Apparatus of the present invention provides innovative real-time system power management with respect to user presence by using an image-capturing device and computer vision technology. The image-capturing device is to capture an image that includes an area in front of a computer system. The image is to be analyzed to determine the user presence. When it is determined that the user is not present, one or more components of the computer system is placed in a power saving mode.

Abstract: A computer is power managed by detecting the presence of a user. A camera is associated with the computer and the output from the camera is analyzed to determine if the user is present. If the user is present, then the computer is maintained in its non-power manage state. When the user leaves, however, the user's presence is no longer detected by the camera, and the power managed state can be quickly entered.

Abstract: In accordance with one embodiment, the invention provides a method comprising monitoring a power consumption of a processor in executing a program while running in a speculative execution mode wherein instructions are speculatively executed; and turning off said speculative execution mode if said power consumption is above a predetermined threshold. According to another embodiment the invention provides a processor comprising a speculative mode wherein instructions are speculatively executed; a non-speculative execution mode wherein instructions are executed non-speculatively; and a speculation control mechanism to selectively cause said processor to operate in said non-speculative mode based on a power consumption criterion.

Abstract: A method and apparatus to identify an occurrence of a predetermined event, and reduce power consumption of a display controller in response to the predetermined event. Identifying the occurrence of the event includes identifying a display is in a reduced power mode.

Abstract: A computer system may include a camera to perform various video imaging functions. The camera may also be used to measure ambient light. The brightness of the display screen of the computer system may be adjusted in response to this measurement of ambient light. For example, the display screen brightness may be increased if the ambient light increases, and decreased if the ambient light decreases. In addition, in accordance with one embodiment of the present invention, the position of the user may be determined, and the ambient light may be measured in the vicinity of the user.

Abstract: A power management apparatus includes a sensor and a display coupled with the sensor. The display is powered off when the sensor detects absence of a user and the display is powered on when the sensor detects presence of the user.

Abstract: A power management apparatus includes a sensor and a display. For one embodiment, power to the display may be decreased when the sensor detects absence of a user, and the power to the display may be increased when the sensor detects presence of the user.

Abstract: A circuit for executing a logical majority operation in a computing system. The logical majority operation operates on multiple operands to determine the majority value of the operands. The circuit of the present invention includes circuitry for receiving multiple operands, logic for executing a logical majority operation in one clock cycle and circuitry for outputting a result of the logical majority operation.
