Publication number: 20240142626Abstract: A system and method receive a first beam pattern from an optical source that includes optical beams transmitted towards a target. The system and method measure a first vertical angle between at least two of the optical beams along a first axis relative to the FMCW LIDAR system. The system and method calculate a second beam pattern based on the first vertical angle and a pivot point. The second beam pattern produces a second vertical angle between the two optical beams. The system and method adjust one or more components from a first position that forms the first beam pattern to a second position that forms the second beam pattern for transmission towards the target. The system and method receive one or more return optical beams from the target, based on the second beam pattern, to produce a plurality of points to form the point cloud.Type: ApplicationFiled: April 27, 2023Publication date: May 2, 2024Inventors: Cameron Howard, Sawyer Isaac Cohen, Keith Gagne, Bradley Scot Levin, Pierre Hicks

Patent number: 7001497Abstract: A spent anode is replaced with a new anode in an electrolysis cell having an anode bus bar and an anode rod contacting the bus bar. A desired distance (D4) from the bus bar to a reference point on or adjacent to an anode rod for the new anode is calculated, the spent anode is replaced with a new anode so that the reference point on the new anode rod is spaced from the bus bar by an actual distance (D5), and the actual distance (D5) is measured at least once by means of a vision system. The actual distance (D5) is preferably adjusted using a feedback control loop in a computer so that D5 approaches the desired distance (D4).Type: GrantFiled: April 25, 2003Date of Patent: February 21, 2006Assignee: Alcoa,Inc.Inventors: Jean Pierre Gagné, Gilles Dufour, Bertrand St-Laurent, Claude Gauthier, Jacques Denis, Robin Boulianne, Pierre Bouchard, Jacques Pelletier
