Embodiments of the present invention provide end-to-end frame time synchronization designed to improve smoothness for displaying images of 3D applications, such as PC gaming applications. Traditionally, an application that renders 3D graphics functions based on the assumption that the average render time will be used as the animation time for a given frame. When this condition is not met, and the render time for a frame does not match the average render time of prior frames, the frames are not captured or displayed at a consistent rate. This invention enables feedback to be provided to the rendering application for adjusting the animation times used to produce new frames, and a post-render queue is used to store completed frames for mitigating stutter and hitches. Flip control is used to sync the display of a rendered frame with the animation time used to generate the frame, thereby producing a smooth, consistent image.

Systems and methods for frame time smoothing based on modified animation advancement and use of post render queues

A raster unit is configured to generate different sample patterns for adjacent pixels within a given frame. In addition, the raster unit may adjust the sample patterns between frames. The raster unit includes an index unit that selects a sample pattern table for use with a current frame. For a given pixel, the index unit extracts a sample pattern from the selected sample pattern table. The extracted sample pattern is used to generate coverage information for the pixel. The coverage information for all pixels is then used to generate an image. The resultant image may then be filtered to reduce or remove artifacts induced by the changing of sample locations.

Enhanced anti-aliasing by varying sample patterns spatially and/or temporally

Electrical power unit

An electrical connector including first and second connector parts configured for mating together, and with one of the connector parts having a sensory feedback member that moves between an extended position and a retracted position as a result of magnetic interaction with an actuation element in the other connector part during mating of the connector parts. The movement of the sensory feedback member causes a sensory feedback indication, such as an audible sound or a tactile vibration.

Electrical connector with haptic feedback

A portable electrical power unit includes a housing defining an interior region that receives a power source, such as a rechargeable battery or capacitor, and one or more electrical connectors that are accessible at or through outer surfaces of the housing. The housing includes a substantially flat base for resting atop generally horizontal surface, and may include a power switch for selectively energizing the outlets. Optionally, a charging indicator provides a visual indication of the current capacity or charge level of the onboard power source. The power unit may receive or convey electrical power via direct-contact electrical terminals or via inductive power transmission, and may include additional features such as a location-detecting circuit operable to detect and generate a signal in the event that the power unit is moved out of a predefined area.

Electrical power unit for a work surface

A branched electrical system is adapted for providing multiple users with access to high and/or low voltage electrical power in work areas or high density seating areas, such as stadium or theater seating, work rooms, lecture halls, and public transportation vehicles. The system includes a main line and a plurality of branch lines, each branch line having at least one high voltage or low voltage electrical receptacle that is accessible to a user located at the seating, such as for powering a portable electronic device. The branch lines may be coupled to the main line via a splice or other electrical-mechanical connection.

Branched electrical system

An electrical receptacle assembly is mountable at an opening in a work surface to provide convenient access to electrical power and/or data. The assembly includes a main housing and a housing shell. The main housing defines an interior cavity for receiving a lower portion of an electrical or data outlet, and has an outlet opening in which a face of the electrical or data outlet is supported. The housing shell is coupled to the main housing and surrounds at least a portion of the interior cavity. Respective outer surfaces of the main housing and the housing shell cooperate to form an outer surface of the two-piece housing that is insertable into the opening in the work surface. A fastener, which may be an internally threaded collar, engages the two-piece housing, which may be externally threaded, and also engages the work surface, to secure the assembly to the work surface.
