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.

An apparatus for sorting objects is described, and which provides high-speed image data acquisition to fuse multiple data streams in real-time, while intentionally creating and utilizing known signal interference to enhance contrasts when individual sensors or detectors are utilized in providing data regarding features of a product to be inspected.

A system and a method of sorting scrap particles is provided. A moving conveyor containing scrap particles is imaged using a vision system to create a vision image corresponding to a timed location of the conveyor, and is sensed using a sensing system to create a sensing matrix corresponding to the timed location. The sensing system has at least one array of analog proximity sensors. A control system analyzes the vision image as a vision matrix of cells, and generates a vision vector containing vision data from the vision matrix for the particle. The control system analyzes the sensing matrix, and generates a sensing data vector containing sensing data from the sensing matrix for the particle. The control system classifies the particle into one of at least two classifications of a material as a function of the vision data vector and the sensing data vector.

A method and apparatus for sorting is described, and which includes an arrangement for controllably and operably coupling to a controller, and then selectively energizing each of a background element; laser scanner; first and second electromagnetic radiation detectors; line scan imaging assembly; and selectively energizable radiators, so as to improve the detection of individual products and/or other objects of interest forming a product stream by increasing the contrast of the respective products or specific characteristics thereof, and/or objects of interest in a multiplicity of electrical signals which are received, and then processed by the controller, as the product stream passes through an inspection station.

A system for sorting objects is provided. For instance, the system includes a first and second sensor for observing the objects before and after sorting and a controller having an action agent module and a learning agent module. The controller updates, by the learning agent module, a policy matrix after sorting previously sorted objects. The policy matrix includes state data of the previously sorted objects including sensor data, an action performed by the sorting actuator, and a sorting score. The controller actuates the sorting actuator, calculates a specific sorting score based on a specific action performed by the sorting actuator, and updates the policy matrix to create an updated policy matrix including updated sorting rules. The updated policy matrix is used in sorting subsequent objects. In another example, the controller loads a policy matrix that was determined incrementally during sorting of previously sorted objects.

An object detection method includes an electromagnetic radiation emitter, and an electromagnetic radiation detector on a first side of an inspection zone, a reflective background on a second side of the inspection zone and a controller operably connected to the emitter and the detector to measure/determine a first time of travel for emitted electromagnetic radiation waves/pulses to travel from the emitter, to the reflective background, and return to the detector, and to measure/determine a second time of travel for emitted electromagnetic radiation waves/pulses to travel from the emitter of electromagnetic radiation to objects of interest passing through the inspection zone along an unsupported path of travel and to be reflected to the electromagnetic radiation detector, and any determined time of travel which varies from the first time of travel is evidence there is an object within the inspection zone and between the emitter and the reflective background.
