  • Publication number: 20080158654
    Abstract: According to one embodiment of the present invention, a method of displaying an image includes alternating an active state of each of a plurality of light sources. The light sources each generate a light beam when active. The alternating includes deactivating an active light source before an output of a light beam from the active light sources falls below a first predetermined threshold. The alternating further includes activating an inactive light source only after an output of the inactive light source reaches a second predetermined threshold. The method further includes receiving each of the light beams at a modulator. The modulator includes an array of micro-mirror devices.

  • Publication number: 20080159415
    Abstract: A novel and useful baseline wander correction mechanism for use with transformer coupled baseband communication receivers. Parametric estimation of the transformer model is used estimate and cancel the baseline wander effect. A parametric model is used to model the baseline wander impairment created by the transmitter and receiver transformers as a high pass filter having an exponential decay parameter alpha. A correction signal for both the far end and echo signal paths are calculated and summed to generate a total correction signal. The total correction signal is partitioned into an analog correction signal that is applied to the analog portion of the communications receiver and into a digital correction signal that is similarly applied to the analog portion of the communications receiver.
