Sorting device and sorting method

TL;DR: In this paper, a conveyor belt is used to carry a stream of randomly-arranged post-consumer plastic articles made of PVC and PET to an irradiation area where they are irradiated with ultraviolet light that induces the postconsumer articles of PVC to emit fluorescent light that persists after the irradiation ends.

TL;DR: In this article, a method and system for identifying a molded container such as a glass bottle with its mold of origin, and a corresponding container is presented. But the method is based on the assumption that a source of diffused light energy is reflected by the container heel, with such energy having an intensity gradient at predetermined orientation with respect to the container axis.

TL;DR: In this article, a line detector is used to measure the level of the directly reflected light at the surface of a tomato moving in the direction x-x through a scanning zone.

TL;DR: In this article, a light sensor module (1) comprises a plurality of light sensing elements (2) arranged on a substrate (4), where each element is arranged to make electrical connection (8) to the substrate through the opposed surface (18), leaving the sides (19) of the element substantially free.
