  • Publication number: 20240103215
    Abstract: An advance in the art is made according to aspects of the present disclosure directed to methods for earthquake sensing that employ a supervisory system of undersea fiber optic cables. Earthquakes and other environmental disturbances are detected by monitoring the polarization of interrogation light instead of its phase. More specifically, our methods monitor the transfer matrix rather than just polarization and isolate disturbance location by monitoring eigenvalues of the polarization transfer matrix. From results obtained we have demonstrated experimentally that we can monitor disturbances that affect signal polarization on a span-by-span basis using High Loss Loop Back (HLLB) paths. It is shown that by measuring the polarization rotation matrix and determining the polarization rotation angle we can identify the span where the disturbance occurred with 35 dB extinction with no limitation on the magnitude of the disturbance and the number of affected spans.

  • Patent number: 11915093
    Abstract: Disclosed herein are methods and systems for encoding data in composite patterns such that the encoded data is perceptible in one or more infrared spectral ranges while significantly imperceptible in visible light spectral range by encoding the data in one or more first partial patterns and/or in one or more second partial patterns of the composite pattern where the first partial pattern(s) is painted using a first print material and the second partial pattern(s) is painted using a second. The first and second paint materials are characterized by reflecting substantially similar light in the visible light spectral range and significantly different light in the infrared spectral range(s) such that the first and second patterns are indistinguishable in the visible light spectral range while highly distinguishable in the infrared spectral range(s). further disclosed are methods and systems for decoding the composite patterns to decode and extract the encoded data.

  • Patent number: 11900695
    Abstract: Disclosed herein are methods and system for detecting road marking expressed using alternating infrared reflective tiles comprising high infrared reflective tiles and low infrared red reflective tiles painted on a road surface using paint material(s) characterized by: (1) reflecting light in visible light spectral range deviating less than a first value from the light reflected by the road surface and (2) reflecting light in an infrared spectral range deviating more than a second value from the light reflected by the road surface. Infrared image(s) and visible light image(s) of the road surface which are registered to each other may be analyzed to compute an infrared reflective value and a luminance value for each pixel respectively. A ratio may be computed between the infrared reflective value of and the luminance value of corresponding pixels to identify high and low infrared reflective tiles in pixels having a ratio exceeding a third value.
