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: Interposer assemblies may be inserted between a traditional shelf and traditional supports for the shelf. Each of the interposer assemblies may be configured to generate signals corresponding to changes in loading on the traditional shelf, and information regarding the changes may be determined to identify items placed onto or removed from the traditional shelf, and locations at which the items were placed or from which the items were removed. The interposer assemblies may include one or more load cells, such as strain-gage load cells, and analog signals generated by the load cells may be processed to determine a mass of an item placed on the shelf or removed therefrom. The item, and a location corresponding to the item, may be determined based on the mass and according to standard equilibrium procedures.

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.
