    摘要: Text is rendered to a television screen using only the alpha channel. This is accomplished by delaying blending with underlying video until the end of the process to thereby preserve the alpha channel information. Glyphs are used to graphically represent character data in the text to be rendered. Glyphs can be stored in a character texture. In addition, the glyphs can be contained in rectangles having identifiable locations in the character texture. The rectangles can have sizes dependent upon the glyph the rectangle contains.

    摘要: A contrast medium injector for injecting a patient with contrast medium for a CT scan is programmed to provide an injection protocol that is a representation of an ideally defined exponential curve with an initial injection rate decaying at an exponential rate. This has been found to produce a uniform vascular enhancement for the scanning of a patient's blood vessels. The particular exponential decay coefficient which has been found to be optimal is directly proportional to the cardiac output divided by the patient's weight and is approximated at 0.01 for a typical human.

    摘要: A system and method for testing a set top box includes a test manager module in communication with the set top box having a test script including a bitstream. A bitstream player in communication with the test manager module receives the bitstream and communicates the bitstream to the set top box. The test manager module receives a screen image from the set top box that is generated in response to the bitstream. An optical character recognition module performs optical character recognition to obtain a test text string from the screen image. The test manager module compares the test text string with an expected text string. A report module generates a report in response to comparing.
