  • Patent number: 11407595
    Abstract: Methods and apparatuses for performing article singulation are provided. An article singulator can include an intake conveyor, an out-take conveyor, and multiple intermediate conveyors. The intake conveyor can receive multiple articles and convey the articles to the multiple intermediate conveyors. Further, the out-take conveyor may convey singulated articles from amongst the multiple articles (e.g. to an outfeed). Further, the multiple intermediate conveyors may include successive conveyors to convey the articles and provide the singulated articles to the out-take conveyor. In some examples, each successive conveyor of the multiple intermediate conveyors may be positioned at a lower level than a preceding conveyor. Further, each successive conveyor can convey the articles in a different direction and at a different speed than a preceding conveyor such that the articles are singulated upon conveyance by the article singulator.

  • Patent number: 10674142
    Abstract: Sensor fusion is utilized in an electronic device such as a head mounted display (HMD) device that has a sensor package equipped with different sensors so that information that is supplemental to captured 2D images of objects or scenes in a real world environment may be utilized to determine an optimized transform of image stereo-pairs and to discard erroneous data that would otherwise prevent successful scans used for construction of a 3D model in, for example, virtual world applications. Such supplemental information can include one or more of world location, world rotation, image data from an extended field of view (FOV), or depth map data.
