  • Optical network terminal (ONT) wavelength tuning and correpsonding calibration procedure
    Patent number: 9780908
    Abstract: Tuning an optical network unit (ONU) to an appropriate communication wavelength may be performed by initiating an activation procedure responsive to receiving a wavelength configuration message, and identifying an instruction in the wavelength configuration message to modify a present wavelength used by the network unit to a different wavelength. The process may also provide assigning an optical network unit identifier (ONU-ID) to the network unit, modifying the present wavelength to the different wavelength, and transmitting subsequent data messages from the network unit at the different wavelength.

  • Videoconferencing Technique
    Publication number: 20140002577
    Abstract: An videoconferencing technique comprises a display substrate occupying less than an entirety of a viewing area; an actuator configured to move the display substrate over the viewing area; a camera having a field of view at least partially overlapping the viewing area and configured to capture a camera image through the viewing area. A transmitter is configured to transmit, through a transmission medium, a signal comprising videoconferencing data; a receiver is configured to receive the signal from the transmission medium and at least a portion of the transmission medium comprises a free space transmission region.
