Abstract: A bulk sorting system for sorting objects in bulk is provided. The bulk sorting system includes: at least one radiation source arranged to radiate the objects, at least one optical sensor arranged to capture reflected radiation of the objects and acquire the reflected radiation as multi- or hyperspectral data; a processing circuit configured to analyze the reflected radiation of the objects by inputting the multi- or hyperspectral data into a convolutional neural network (CNN) with at least two convolutional layers in order to either detect and classify the objects in the multi- or hyperspectral data and/or semantically segment the multi- or hyperspectral data; and a mechanical sorter configured to sort the objects according to their classification and/or segmentation using the analysis of the processing circuit such that different overlapping and/or stacked objects are separated or treated as a single group of objects.

Abstract: A nozzle device for sorting objects by ejecting a gaseous media towards said object. The nozzle device nozzle device including: a nozzle unit including at least one nozzle; a nozzle bar including gas supply means for providing a gaseous media to said nozzle unit; and a nozzle fixation bracket adapted for holding said nozzle unit in place; said at least one nozzle including: an inlet for receiving the gaseous media; and having one outlet, having an outlet area, for ejecting the gaseous media towards an object to be sorted; a channel extending between said inlet and said outlet; an outlet portion surrounding at least said outlet, wherein said outlet portion including a flexible material, which deflects upon ejection of the gaseous media, received from said nozzle bar, through said outlet whereby said outlet area increases. Also, a system for sorting objects.

Abstract: A method for identifying the presence of partly liberated diamonds in a material stream. The method including illuminating a material with a multi-wavelength beam including at least one monochromatic SWIR laser beam, and at least one IR scatter-/anti-scatter laser beam. A sorting process including ejecting objects including material classified as diamond from a transportation direction of the material stream.

Abstract: A method for object classification, including: guiding a continuous stream of objects from a transport mechanism directly into an unsupported path, along which the object stream is fed through a detection region; illuminating the detection region with a radiation band in a first direction; optically scanning the detection region to detect electromagnetic radiation reflected by the at least one object in the detection region by viewing the detection region along a second direction, wherein the directions have a cross-section in the detection region and form an angle relative each other of 10°-80°; analyzing the information; and classifying objects in at least two different directions based on the analysis of the transparency information from the optical scanning; wherein the step of analyzing the information from the optical scanning includes analyzing the objects based on the intensity, spread and texture of the detected radiation from the optical scanning.

Abstract: A method for identifying the presence of partly liberated diamonds in a material stream. The method can include illuminating a material with a multi-wavelength beam including at least one monochromatic SWIR laser beam, and at least one IR scatter-/anti-scatter laser beam, capturing a portion of the at least one monochromatic SWIR laser beam after the monochromatic SWIR laser beam has been reflected and/or scattered by the material, producing a SWIR signal based on the captured portion of the at least one monochromatic SWIR laser beam, and capturing a first portion of the at least one IR scatter-/anti-scatter laser beam after the at least one IR scatter-/anti-scatter laser beam has been scattered and optionally reflected by the material.
