  • Publication number: 20110102598
    Abstract: A device for illuminating a target comprises a laser which produces a light beam, a viewing medium which receives electromagnetic radiation in an acceptance band, a beam-splitter which splits the light beam into a first beam and a second beam, and an imaging assembly. The imaging assembly comprises a light conversion medium and an element responsible for image creation comprising one of a light focusing medium and a light reflective medium. The first beam is directed along a travel path from the beam-splitter to the element and then to the light conversion medium, wherein the light conversion medium converts the first beam into electromagnetic radiation within the acceptance band. A spot object distance between the light conversion medium and the element is less than a target distance. The target distance is between the target and the beam-splitter less a distance between the beam-splitter and the element.

  • Publication number: 20090180636
    Abstract: In a communication machine room wideband noise suppression system, a sensing unit detects a noise source produced by a fan during the operation thereof and generates a noise input signal and a feedback signal, which are sent to a signal amplifying unit for signal amplification. The amplified signals are then sent to a signal converting unit and converted into digital signals. A multi-channel hybrid controller receives the digital signals and makes corrections and conduct rapid convergence algorithm to derive a reverse digital signal, which is sent to the signal converting unit and converted into a reverse analog signal. The reverse analog signal is sent to the signal amplifying unit for power amplification to generate a control signal for driving a loudspeaker unit to produce interfering acoustic wave, so as to cancel out the noise source and achieve the purpose of eliminating wideband noise.
