Abstract: Disclosed herein are visual display systems and methods capable of having shifted bit-weights in neutral density filtering (NDF) applications. In one embodiment, a method (200) of displaying an image comprises transmitting light through an optical filter (17) comprising at least one high transmissivity portion configured to output light at an initial intensity, and at least one low transmissivity portion configured to output light at a lower intensity than the initial intensity, where the initial intensity and lower intensity output light illuminates a spatial light modulator (14). The method also includes providing a plurality of data bits (non-ND) from a predetermined number of data bits (B0–B7), where each of the plurality comprises a pulse-width longer than a load-time for operating the spatial light modulator (14).

Abstract: An interactive television that combines the video/audio content, delivered by existing broadcast methods, with the interactive Internet capabilities, delivered by existing network methods. In this approach, mixed media, including fall frame-rate high definition video, audio, text, and graphics are delivered via mixed transmission mediums, both traditional broadcast and the Internet. This provides for personalized content, both video and Internet, and allows interactive content to be developed by third parties.

Abstract: The present invention includes a method and apparatus for performing intrusive testing upon a microprocessor to ensure the absence of errors or defects in performance-enhancing features and related control circuitry which affect the results of software instructions being executed by the microprocessor. In the intrusive testing method, an intrusive testing unit capable of generating logic signals is coupled between a computer system motherboard and a microprocessor. The microprocessor is then caused to execute a test software program. As the microprocessor executes the test software program, the intrusive testing unit generates logic signals (alternate control signals) at regular intervals. Control signals generated by system hardware on the motherboard in response to program execution are logically combined with alternate control signals generated by the intrusive testing unit. Resulting output control signals are applied to the control signal pins of the microprocessor.
