A method and a system provide a feedback data indicating quality of a food processing performed by an operator. The method and system involve acquiring at least one image data of a food product from an operator; and processing the acquired image data. The processing includes detecting whether undesired objects are present in the food product, obtaining, in case undesired objects are detected, position data of the undesired objects within the food product, and utilizing the position data in issuing a feedback indicator indicating a position where the detected undesired objects are present within the food product processed by the operator.

Additive manufacturing can involve dispensing a powdered material to form a layer of a powder bed on a support surface of a build platform. A portion of the layer of the powder bed may be selectively melted or fused to form one or more temporary walls out of the fused portion of the layer of the powder bed to contain another portion of the layer of the powder bed on the build platform.

An additive manufacturing system including a two-dimensional energy patterning system for imaging a powder bed is disclosed. Improved optical systems supporting beam combining, beam steering, and both patterned and unpatterned beam recycling and re-use are described.

The automated assembly and manufacture of a sandwich includes a number of robots that are used to slice, open, and add inputs to a roll of bread. The inputs may be sliced and portioned at individual stations and then the inputs can be delivered to the bread or the bread can be conveyed to the inputs. In either sense, the selected inputs are added to the bread, based on the type of sandwich to be assembled. The assembled sandwich is then conveyed to a packaging station, where the sandwich is packaged, labeled, and prepared for shipment.

The present disclosure relates to a method, apparatus, device and storage medium for information processing. Specifically, a method is proposed for information processing. In the method, multiple samples associated with multiple ordinal data in an application system are obtained, each sample among the multiple samples comprising multiple dimensions, a dimension among the multiple dimensions corresponding to ordinal data among the multiple ordinal data. Based on the multiple samples, a first causal structure and a second causal structure representing the causality between the multiple ordinal data are provided, the second causal structure being obtained based on the first causal structure. Further, there is provided an apparatus, device and storage medium for information processing. With example implementations of the present disclosure, the first causal structure and the second causal structure are provided based on the multiple samples, the causality may be determined in a simple and effective way, and the credibility of the causality may be increased.

An apparatus and a method for powder bed fusion additive manufacturing involve a multiple-chamber design achieving a high efficiency and throughput. The multiple-chamber design features concurrent printing of one or more print jobs inside one or more build chambers, side removals of printed objects from build chambers allowing quick exchanges of powdered materials, and capabilities of elevated process temperature controls of build chambers and post processing heat treatments of printed objects. The multiple-chamber design also includes a height-adjustable optical assembly in combination with a fixed build platform method suitable for large and heavy printed objects.

A monitoring device monitors a status of a process in a production line in separate unit tasks. The production line includes a plurality of processes. The unit tasks form the process. The monitoring device includes an operational condition acquisition section, a determination section, and an output section. The operational condition acquisition section acquires, on a per-unit task basis, operational conditions of a device being used in the tasks. The determination section determines whether or not the acquired operational conditions are appropriate based on preset reference values. The output section outputs, on a per-unit task basis, information as to whether or not the process is being appropriately performed, based on results of the determination.

Methods and apparatuses for determining a property of a structure fabricated on a substrate, by: determining a measured characteristic from pixels of a measured pupil image of the structure, the measured characteristic having less information than the measured pupil image; generating an initial simulated characteristic corresponding to the measured characteristic and based on a candidate model of the structure; comparing the measured characteristic to the simulated characteristic in an iterative method until a difference therebetween is less than a coarse threshold; generating an initial simulated pupil image based on the coarse model as the candidate model; comparing at least a portion of the measured pupil image to at least a portion of the simulated pupil image in an iterative method until a difference therebetween is less than a fine threshold.
