Abstract: In general, in one aspect, a laptop computer includes two planes of orthogonal proximity sensors that are utilized to create a three dimensional user interface. The planes of proximity sensors are provided in the display and the keyboard. The intersections of the proximity sensors along three axis defines a plurality of coverage areas. An object (e.g., users finger, pointer) is determined to be within a coverage area if the corresponding intersecting proximity sensors indicate presence of the object. A user may identify an item on the display for selection by placing an object within an appropriate coverage area and select the item by moving the object toward the display. A user may identify an action to be taken on the display by moving an object through one or more of the coverage areas. A 3D image of an object may be generated based on the coverage areas indicating the object is located therein. The 3D image may utilized to authenticate a user.

Abstract: An apparatus may include a processor and first logic operable on the processor to output a direct memory access (DMA) activity indicator to indicate a current state of activity of direct memory access data transfer operations. The apparatus may further include second logic operable on the processor to determine scheduled DMA activity to be performed; and third logic operable on the processor to output a pre-wake indicator to a controller before the scheduled DMA activity is to be performed, to satisfy both Quality of Service (QOS) and Power saving needs. Other embodiments are disclosed and claimed.
