Abstract: A multi-modal adaptive fusion deep clustering model based on an auto-encoder includes an encoder structure, a multi-modal adaptive fusion layer, a decoder structure and a deep embedding clustering layer. The encoder is configured to enable a dataset to be respectively subjected to three types of nonlinear mappings of the auto-encoder, a convolutional auto-encoder and a convolutional variational auto-encoder to obtain potential features, respectively. The multi-modal adaptive feature fusion layer is configured to fuse the potential features into a common subspace in an adaptive spatial feature fusion mode to obtain a fused feature. The decoder is configured to decode the fused feature by using a structure symmetrical to the encoder to obtain a decoded reconstructed dataset. The deep embedding clustering layer is configured to cluster the fused feature Z and obtain a final accuracy ACC by comparing a clustering result with a true label.

Abstract: The invention discloses a regulating system and method for multilayer shading film of plastic greenhouse with adjustable shading rate. The upper film of the sunshade is a fully transparent film, while the middle film and the lower film are printed with dots, which are interlaced. Through the measurement and comparison of the warm light in the greenhouse, the combined control of the sunshade film is realized. Not only can it adjust its light blocking rate, but it also has a heat insulating effect when there is a certain amount of air in the film.

Abstract: A design of optical testing device or system for fiber arrays is disclosed. According to one aspect of the invention, an array of light sources and an array of detectors are disclosed. One of the light sources is controlled to be turned on to test a designated fiber in an array of fibers being tested for connection issues. A microcontroller is configured to determine which one of the detectors is detecting a light beam from one of the light sources, and mark a channel of the array of fibers accordingly depending on if the one of the detectors is supposed to detect the light beam; if another one of the detectors detects the light beam; or if none of the detectors detects the light beam.

Abstract: A variable optical attenuator is provided. The variable optical attenuator includes an input optical fiber, an output optical fiber, a non-attenuating, transmission-type diffracting prism and a prism positioning system. The input optical fiber, the non-attenuating, transmission-type diffracting prism and the output optical fiber are optically arranged such that an optical path from the input core of the input optical fiber to the output core of the output optical fiber passes through the non-attenuating, transmission-type diffracting prism. The non-attenuating, transmission-type diffracting prism diffracts an optical signal propagating from the input optical fiber to the output optical fiber such that an input portion of the optical path is non-linear with an output portion of the optical path. The prism positioning system changes a pose of the non-attenuating, transmission-type diffracting prism within the optical path thereby attenuating the optical signal.
