Abstract: Footprint data of an item that is representative of a boundary of the item and where that boundary is located is obtained using occlusion of a projected line. Line projectors are arranged at opposite sides of a conveyor belt and at an angle that is acute with respect to a plane of the conveyor belt and produce lines on the conveyor belt within a measurement area. As an item moves past the measurement area, the sides of the item occlude a portion of the projected lines. Cameras acquire a series of images as the object moves with respect to the measurement area. The images are processed to determine where the projected lines were occluded. An edge point is then determined representative of that location. One or more lines may be fitted to a plurality of edge points to determine the boundary of the item.

Abstract: An ink that is detectable using infrared (IR) light may be used to apply machine readable codes, such as a barcode. The indicia, once applied, may be either invisible or difficult to detect with visible light, such as with the human eye. The ink may include one or more materials such as titanium dioxide (TiO2), particles of acrylonitrile butadiene styrene (ABS), metals, and so forth. These materials may be used to enhance one or more of the reflectivity to IR light or the fluorescence of the ink under IR light. The fluorescent ink may be deposited in a single pass, or as part of a two-pass process in which a reflective substrate, such as a resin with encapsulated TiO2, is applied and then the fluorescent ink is deposited atop the substrate. The markings are machine readable even when overprinting markings that are readable under visible light.

Abstract: This disclosure describes, in part, techniques for identifying facility status updates using opportunistic data gathering from independently controlled devices operated by users within the facility. For instance, system(s) may determine first status information for inventory and/or locations within the facility and determine associated freshness scores. In response to a freshness score being below a threshold level, the system may determine imaging locations for the independently controlled devices to be positioned at to capture image data to update information on the inventory or locations. The system may receive uploaded image data from a fleet device after it opportunistically reaches the imaging location and captures image data. The system may then update the facility status information and the freshness score for the particular location.
