Patent number: 11081863Abstract: An optical device comprises a light input, a light modulating means and a light output. The optical device further comprises an optical amplification device arranged to amplify light travelling between said light modulating means and said output. The optical amplification device comprises first and second serially connected post SOA (Semiconductor Optical Amplifier) units, each comprising at least one respective serially connected post SOA segment, which device is arranged to vary a light amplification by varying respective SOA bias voltages across said post SOA segments. A total SOA length of the first post SOA unit is relatively longer than a total SOA length of the second post SOA unit, which is relatively shorter. The optical device is arranged to, during operation using a particular operation program, always keep respective SOA bias voltages across each of the post SOA segments of the first post SOA unit at +0.5 V or more.Type: GrantFiled: April 13, 2018Date of Patent: August 3, 2021Assignee: FINISAR SWEDEN ABInventors: Jan-Olof Wesström, Per Granestrand, Martin Anders Isak Stattin, Staffan David Hellström

Patent number: 10480948Abstract: A method performed by a boundary estimation system for estimating a boundary of a road on which a vehicle is positioned and which comprises at least a first lane marking. The system monitors surroundings of the vehicle, detects one or more positions of the at least first lane marking, and approximates a geometrical representation of the at least first lane marking based on one or more of the detected positions of the at least first lane marking. The system further detects one or more positions of a road boundary of the road, approximates a relative lateral offset between the geometrical representation of the at least first lane marking and the detected road boundary, and defines a fictive outer boundary of at least a section of the road based on laterally shifting at least a section of the geometrical representation of the at least first lane marking the relative lateral offset.Type: GrantFiled: March 3, 2017Date of Patent: November 19, 2019Assignee: VOLVO CAR CORPORATIONInventors: Claes Olsson, Anders Dahlback, Martin Anders Karlsson

Patent number: 10041891Abstract: A system for radiographic inspection of welds from at least a portion of a vertical wall such as the wall of a storage tank for gas or oil wherein the wall comprising a plurality of metal plates connected by means of the welds, the system comprising a frame comprising a first sub frame arranged to be positioned, in use, on a first side of the portion of the wall and a second sub frame arranged to be positioned, in use, on a second side of the portion of the wall which lays opposite to the first side of the portion of the wall. The system comprises a radiation source which is attached to the first sub frame for transmitting electromagnetic radiation towards the weld and a radiation detector which is attached to the second sub frame for detecting radiation which has traveled through the weld for carrying out the inspection.Type: GrantFiled: February 26, 2015Date of Patent: August 7, 2018Assignee: RONTGEN TECHNISCHE DIENST B.V.Inventors: Marcel Meijlom Molenaar, Martin Ander Hartwigsen, Bernardus Norbertus Mulder
