Method and interface for sending vertex data output from a vertex processing unit to memory is described. Conventionally, the vertex data output is not output directly to memory via a dedicated write interface, but is instead passed through downstream computation units in a graphics processor and written to memory via the write interface normally used to write pixel data. When the downstream computation units are configured to pass the vertex data output through unmodified, processing of the ver...

A method and system implemented in an application programming interface (API) and an object model allows program code developers to interface in a consistent manner with a scene graph data structure to output graphics. Via the interfaces, program code writes drawing primitives such as geometry data, image data, animation data and other data to visuals that represent a drawing surface, including validation visual objects, drawing visual objects and surface visual objects. The code can also specif...

A detector system that contains two inlet port coupled to a photoionization chamber. One inlet port allows for the introduction of a test sample. The test sample may contain contaminants, drugs, explosive, etc. that are to be detected. The other port allows for the simultaneous introduction of a standard sample. The standard sample can be used to calibrate and/or diagnose the detector system. Simultaneous introduction of the standard sample provides for real time calibration/diagnostics of the d...

A modified universal asynchronous receiver transmitter (UART) device is provided with an auxiliary high speed parallel channel using supplementary FIFO buffers for the exchange of data. The auxiliary parallel channel is separate from the normal lower speed serial channel which is retained in unmodified form. The retained serial channel provides full compatibility with and support for the National Semiconductor 16550 standard, while the auxiliary parallel channel allows for rapid transfer of larg...

A system and a method are disclosed for identifying pixels belonging to moving objects in a series of images by using a signed difference operation. A first signed difference is determined between a first image and a second image. A second signed difference is determined between a second image and a third image. Pixels that change from a positive sign in the first signed difference to a negative sign in the second signed difference belong to the moving object in the second image.

One or more methods and systems of resynchronizing or dynamically retuning a clock signal over a high speed clocked data interface are presented. In one embodiment, the system and method utilizes first and second delay lines, a first pair of digital logic devices to generate a first data sequence, a second pair of digital logic devices to generate a second data sequence, a memory, a set of software instructions resident in the memory, a processor, and a user interface. The first and second data ...

A system and method provides visualization and layout schemes for a circular graphical user interface using global and local polar coordinate systems to display images. The system gives a user of the interface the full capability to relocate, re-orient, scale and layout images in the circular interface. Further, methods are provided to layout images in the Cartesian coordinate system, minimizing overlapping and crowding of images, and supporting users' focus in a group setting for group collabor...

Affordable methods and apparatus are disclosed for inputting position, attitude (orientation) or other object characteristic data to computers for the purpose of Computer Aided Design, Painting, Medicine, Teaching, Gaming, Toys, Simulations, Aids to the disabled, and internet or other experiences. Preferred embodiments of the invention utilize electro-optical sensors, and particularly TV Cameras, providing optically inputted data from specialized datum's on objects and/or natural features of obj...

A method in a computing device for identifying interfaces related to a service provider includes receiving a call identifier as an explicit parameter in a call or as an implicit parameter contained within input data to request a service provided by the service provider, the call identifier representing a version of the service.
