Abstract: A shelter usage alter system includes a wall having an access opening positioned therein. A door is mounted on the wall and is positionable in a closed position or an open position. A locking mechanism is positioned on the door and is actuated from an interior of the shelter for selectively locking the door. The locking mechanism is actuated to a locked position or an unlocked position. A control circuit is operationally coupled to the locking mechanism and the control circuit receives a locked signal when the locking mechanism is in the locked position. A sound emitter is operationally coupled to the control circuit and is positioned outside of the shelter. The sound emitter emits an audible alarm sound when the control circuit receives the locked signal. The sound emitter is positioned adjacent to the shelter.

Abstract: A method and a system of test case reduction in application binary interface (ABI) compatibility testing are provided. The computer-implemented method includes generating test cases consisting of called functions with random numbers and types of arguments, validating that the arguments are correctly passed to the called functions, and, where it is found that arguments are not correctly passed, iteratively narrowing down the set of arguments required to find the minimal number and types of arguments to demonstrate an error in the ABI implementation.

Abstract: Some embodiments of the present invention provide a system that renders graphics in a computing system that includes a plugin associated with a web browser in the computing system and a web application configured to execute in the web browser. During operation, the web application specifies a graphics model and provides the graphics model to the plugin. Next, the plugin generates a graphics-processing unit (GPU) command stream from the graphics model. Finally, the plugin sends the GPU command stream to a GPU of the computing system, which renders an image corresponding to the graphics model.

Abstract: A solar-powered crosswalk warning system is disclosed. The crosswalk warning system comprises two or more crosswalk warning beacons, located on opposite sides of the road. Each beacon comprises a solar panel to recharge a battery, a battery back, a control unit to charge the battery pack during daylight hours, a communication unit to communicate to the second crosswalk beacon, a traffic signal lamp ton warn oncoming traffic, and a triggering means by which the pedestrian can activate the beacons.

Abstract: An application binary interface includes a descriptor specifying a binary shader for each pass of a multi-pass shader. The application binary interface also includes a graphics state of a graphics object for each pass of the multi-pass shader. The graphics state for the first pass is an initial graphics state of the graphics object. The graphics state for each subsequent pass specifies a change from the graphics state of a previous pass. The application binary interface further includes parameters for the binary shaders. The application binary interface links the binary shaders together based on the parameters. Further, the parameters of the binary shaders may be modified at run time to configure the multi-pass shader. The binary shader of each pass is then executed based on the graphics state and parameters of the pass to render the graphics object.

Abstract: A method for calculating a lighting function for an object to be rendered using a basis function is provided. The method includes calculating a transfer function approximation of the lighting function through a stream processor. A method for presenting lighting characteristics associated with a display object in real-time and a method for determining secondary illumination features for an object to be displayed are also provided. A computer readable medium and a computing device having a graphics processing unit capable of determining lighting characteristics for an object in real time are also included.

Abstract: A method for rendering an image with high resolution lighting characteristics is provided. The method initiates with generating a texture map associated with the image. The texture map is defined by texels. Then, a value representing a lighting characteristic for each of the texels is calculated. Next, the value is stored. Then, a coordinate space of the texture map is associated with a display screen coordinate space. Next, the image is rendered on a display screen using the stored value. A method for incorporating the lighting characteristics of an image into a texture map is also provided. A computing device and integrated circuit both configured to present real time shadowing effects are also provided.
