    摘要: An immersive video projection system for a virtual reality simulator includes a plurality of imaging units each configured to project a video image upon a plurality of respective first surface mirrors. The video images reflected off of each of the first surface mirrors are then incident upon a panoramic display having a radius of curvature that matches the radius of curvature of the first surface mirrors, so as to provide a high-fidelity image with reduced artifacts for use in simulating motion of various activities. The immersive video projection system may also utilize an interface system that is configured to provide highly realistic control arrangements that provide realistic levels of feedback thereto, so as to impart a highly realistic and immersive experience to the user of the virtual reality simulator.

    摘要: An apparatus precisely adjusts the delay of a clock signal so as to reduce clock skew. The electronically programmable skew adjustment can be self-contained within a single IC package. The apparatus has an input for receiving a signal to be delay adjusted, delay elements including capacitive delay elements for providing multiple signal paths of various delays, delay selection circuitry for selecting the signal paths so as to select a delay amount, and an output to provide the delay adjusted signal to a load.

    摘要: An apparatus for adjusting signal delay includes an input for receiving a signal to be delay adjusted. A delay circuit is connected to the input means for providing a plurality of selectable signal paths for various delay amounts for producing a delay adjusted signal therefrom. A delay selection circuit is connected to the delay circuit for selecting the signal path so as to select a delay amount and an output provides the delay adjusted signal to a load. Skew compensation is employed on the input and individually on each output to compensate for clock distribution network skew and intracircuit skews, respectively.

    摘要: A method of adjusting clock skew for a computer system, wherein the computer system includes a clock generator for generating a clock signal, at least one logic module and a clock distribution network for carrying the clock signal from the clock generator to the logic modules, includes deskewing each of the logic modules and also deskewing the distribution network between the clock generator and the logic modules. Deskewing is performed by measuring a delay for the clock signal between a clock input and a test point on the logic module, comparing the measured delay to a desired delay, calculating an amount of adjustment needed to cause the measure delay to equal a desired delay and programming a skew compensator on the logic module with a calculator to mount adjustment.
