Patent number: 11373401Abstract: Various techniques are disclosed for the detection of discrepancies between imaged maritime vessels and received identification information. In one example, a method includes capturing an image of a maritime vessel and processing the image to extract information associated with the vessel. The method also includes receiving automatic identification system (AIS) data, comparing the extracted information to the AIS data, and generating an alarm in response to a discrepancy detected by the comparing. Additional methods, systems, and devices are also provided.Type: GrantFiled: June 4, 2019Date of Patent: June 28, 2022Assignee: FLIR Systems ABInventors: Stefan F.

Patent number: 7578905Abstract: Methods for achieving even transverse distribution and propagation of a flowing medium are disclosed in which the flowing medium is supplied through a conduit and is deflected during diverging propagation in at least one distribution gap. The method includes deflecting the flowing medium during diverging propagation along the distribution gap in which the medium is conveyed through a passage to an outlet gap having a larger depth than the depth of the distribution gap. The medium is conveyed over an edge of the passage extending transverse to the direction of the flow, and the edge is designed to obtain a propagation along the flowing path of the diverging medium that provides a substantially even and parallel flow of the medium along the outlet gap. Apparatus for achieving this method is also disclosed.Type: GrantFiled: January 13, 2005Date of Patent: August 25, 2009Assignee: Metso Paper, Inc.Inventors: Jörgen Lundberg, Olof Melander
