Abstract: Monocular depth prediction machine learning models may be trained to receive imaging data of inventory holders having translucent bands that at least partially occlude portions of compartments and items of the inventory holders. The monocular depth prediction models may process the imaging data to generate accurate and reliable depth maps for the inventory holders, while substantially ignoring or disregarding the translucent, partially occlusive bands. Further, the depth maps may be utilized by various occupancy correction models to improve determinations related to available storage space within compartments of the inventory holders, thereby improving the accuracy and efficiency of various material handling processes.

Abstract: A method for synthesizing a crystalline molecular sieve SSZ-13, characterized in that the method comprises bringing the following raw materials into contact in water under a crystallization condition: at least one tetravalent silicon source, at least one trivalent aluminum source, at least one alkali metal compound, choline cations and/or SSZ-13 seed crystals, and hydroxide ions. The method avoids using benzyl trimethyl quaternary ammonium ions (BzTMA+) or N,N,N-trimethyl-1-amantadine cations as structure-directing agents, and obtains high-quality crystal molecular sieve SSZ-13. Due to the use of a low-cost nontoxic structure-directing agent, the method has low production price by employing a low-cost nontoxic template, and can be popularized for application.
