  • Publication number: 20240085211
    Abstract: Embodiments of the present disclosure are directed to various systems, methods and apparatuses for performing simultaneous localization and mapping (SLAM) for a wearable device, including without limitation, a head-mounted wearable device that optionally includes a display screen. Such embodiments enable accurate and quick localization of a wearable device within a dynamically constructed map, optionally through computations performed with a computational device (including those having limited resources). A non-limiting example of such a computational device is a smart cellular phone or other mobile computational device.

  • Publication number: 20070009259
    Abstract: An OSNR reducer adds a prescribed noise spectrum at a prescribed power level to an input optical signal. The OSNR reducer employs at least one optical amplifier to generate the noise and an optical combiner to combine the input optical signal with the noise. Optionally, the OSNR reducer may have a tunable filter that selects a desired wavelength range of the noise and a controller that varies the power level of the noise generated.

  • Publication number: 20060039278
    Abstract: A method and system for maximizing wavelength reuse in an optically protected wavelength-division-multiplexed (WDM) network, the WDM network supporting a plurality of service connections, includes associating service connections supported by non-overlapping paths to form respective service channel groups, and for each service channel group, assigning at least one common wavelength channel for establishing the service connections. In addition, for each of said groups, at least one common wavelength channel is assigned for establishing a shared protection path for the service connections of each of said groups. In addition, the wavelength channels assigned for establishing the shared protection paths for each of the groups may be used for providing service connections for the WDM network when not in use as shared protection paths. However such provisional service connections are dropped when the wavelength channels are needed to establish shared protection paths.
