Because markers are associated with features in the physical space, they maintain their association with the physical space through various processes such as SLAM loop closures. Markers may specify locations in the physical space, such as navigation waypoints, navigation destinations such as a goal pose for exploring an unexplored area, as an observation target to facilitate exploration, and so forth. Markers may also be used to specify block listed locations to be avoided during exploration.Type: GrantFiled: December 3, 2019Date of Patent: December 6, 2022Assignee: AMAZON TECHNOLOGIES, INC.Inventors: James Charles Zamiska, David Allen Fotland, Roger Robert Webster, Mohit Deshpande, Robert Franklin Ebert, Nikhil Sharma, Rachel Liao, Chang Young Kim

Patent number: 11508257Abstract: There is described a method for controlling, in a display, a virtual image of a displaying object for which displaying is controllable. The method comprises providing a curved mirrored surface opposing the displaying object to produce the virtual image. The location of an observer is determined, with respect to the curved mirrored surface. A position of the virtual image can then be determined for the observer at the location, wherein this virtual image provides at least one of parallax and a stereoscopic depth cue. The displaying object is controlled to produce the virtual image as determined.Type: GrantFiled: March 6, 2018Date of Patent: November 22, 2022Assignee: 8259402 CANADA INC.Inventors: Jason Carl Radel, Fernando Petruzziello

Patent number: 11493908Abstract: An industrial safety zone configuration system leverages a digital twin of an industrial automation system to assist in configuring safety sensors for accurate monitoring of a desired detection zone. The system renders a graphical representation of the automation system based on the digital twin and allows a user to define a desired detection zone to be monitored as a three-dimensional volume within the virtual industrial environment. Users can define the locations and orientations of respective safety sensors as sensor objects that can be added to the graphical representation. Each sensor object has a set of object attributes representing configuration settings available on the corresponding physical sensor. The system can identify sensor configuration settings that will yield an estimated detection zone that closely conforms to the defined detection zone, and generate sensor configuration data based on these settings that can be used to configure the physical safety sensors.Type: GrantFiled: November 13, 2018Date of Patent: November 8, 2022Assignee: Rockwell Automation Technologies, Inc.Inventors: Chris John Yates, Maciej Stankiewicz, Jonathan Alexander, Chris Softley
