Abstract: A printing system is disclosed. The printing system includes a color management unit including optimization logic to generate a multi-dimensional color management lookup table derived from an input color to output color mapping, wherein the multi-dimensional color management lookup table has a non-uniform spacing of grid points specifying a correspondence between each of a plurality of input color space dimensions and output color space dimensions, and a color engine to receive an input color in an input color space, perform a multi-dimensional interpolation via the multi-dimensional color management lookup table to map the input color to an output color in an output color space; and return the output color.

Abstract: A thin profile surface mount LED lighting apparatus includes a housing, an LED board including multiple uniformly distributed LEDs, and a lens. The lens has a back side facing the LED board and a front side that provides a downward facing surface when the LED lighting apparatus is installed in an opening of a ceiling. The lens is disposed with respect to the LED board such that the LEDs illuminate the back side of the lens. A first spacing of the LEDs causes resulting light from the downward facing surface of the lens to be substantially uniform during operation of the apparatus. In one example, a thin front edge of a sidewall of the housing, forming a perimeter around the lens, is flush with the lens and is appreciably thin (e.g., a thickness of less than three millimeters), and a depth of the sidewall housing is less than one inch.

Abstract: A densified, high-strength metallic component is manufactured by: binder jet additive manufacture (BJAM) printing a powder blend to form a printed part; and super solidus sintering the printed part to form the metallic component, which may then be heat treated. The powder blend comprises a blend of water atomized base iron powder and a high-carbon master ferroalloy powder. The high-carbon ferroalloy powder introduces high concentrations of carbon into a powder blend that is readily BJAM printable.

Abstract: A firearm holster and a method of making the firearm holster is disclosed. The firearm is wholly or partially molded of ballistic material in such a way that a bullet that is discharged into the holster is retained within the holster or deflected so that it doesn't cause damage to the user of the firearm or other persons or property.

Abstract: A method for greatly reducing data storage requirements of autonomous robots capable of product inventory is described. Instead using high resolution images for label identification and position tracking, a lower resolution map can be searched. Human or machines can identify position of labels, and via a reverse mapping, the corresponding position of a label on the high resolution image can be identified. Except for those portions of the high resolution image showing a label, most of the high resolution image can be discarded. Further processing on the limited image subset can be used to read the labels.

Abstract: A printing system is disclosed. The printing system includes a color management unit including one or more color caches to store input colors and corresponding output colors and a color engine (CE) to receive input colors and perform Force-K transformations to map near black input colors into pure black output colors by dynamically identifying the near black input colors based on chroma values and effective output values.

Abstract: A printing system is disclosed. The printing system includes a color management unit having a common color engine (CCE) to map input colors matching one of more criteria into output colors having a single color component to generate Preserve-X colors and a color cache to store the Preserve-X colors. The Preserve-X colors include the corresponding pairs of input colors and output colors.

Abstract: One embodiment comprises a system that stores a pre-defined color conversion table and a hash table. The system receives user-defined color conversions for a print job, stores them in first locations in the hash table, and marks the first locations as persistent. The system processes the print job utilizing the color conversion table to convert colors in the print job to the output color space, and responsive to encountering colors in the print job that do not have color conversions in the color conversion table, interpolates between color conversions in the color conversion table to generate new color conversions, stores the new color conversions in second locations in the hash table, and marks the second locations as non-persistent. The system determines that the hash table is to be re-initialized, allows reuse of the second locations in the hash table, and prevents reuse of the first locations in the hash table.

Abstract: A system for building a product library without requiring a planogram includes an image capture unit operated to provide images of items. Taking data from a shelf label detector and depth map creation unit, a processing module can be used to compare detected shelf labels to a depth map, define a product bounding box, and associate the bounding box with an image provided by the image capture unit to build image descriptors. The system can include one or more autonomous robots for supporting and moving the image capture unit and other components.

Abstract: A manually assisted robot inventory monitoring method provides for detecting and reading shelf labels using an autonomous robot. Bounding boxes around possible products in a panoramic image can be taken with at least one camera associated with the autonomous robot. Products in the bounding boxes are automatically identified, with those that are not being later manually identified.

Abstract: Embodiments described herein provide for the reuse of some locations in a hash table of color conversions during processing of a print job, while preventing the reuse of other locations. If a determination is made that the hash table is to be re-initialized, then the locations in the hash table that are marked as non-persistent are marked as saved to allow them to be reused, while the locations in the hash table that are marked as persistent are prevented from being reused. During processing of the print job subsequent to re-initialization of the hash table, if a color in the print job does not have a color conversion, then a location in the hash table is identified that is marked as saved. If the location stores the color conversion for the color, then the non-persistent mark is restored for the location to bypass performing a color conversion for the color.
