Patent number: 11864494Abstract: Systems and methods are disclosed herein for detecting impurities of harvested plants in a receptacle of a harvester. In an embodiment, a harvester controller receives, from a camera facing the contents of the receptacle, an image of the contents. The harvester controller applies the image as input to a machine learning model. The harvester controller receives, as output from the machine learning model, an identification of an impurity of the harvested plants. The harvester controller transmits a control signal based on the impurity.Type: GrantFiled: December 12, 2019Date of Patent: January 9, 2024Assignee: Landing AIInventors: Dongyan Wang, Andrew Yan-Tak Ng, Yiwen Rong, Greg Frederick Diamos, Bo Tan, Beom Sik Kim, Timothy Viatcheslavovich Rosenflanz, Kai Yang, Tian Wu

Patent number: 11790270Abstract: A process and a system for creating a visual guide for developing training data for a classification of image, where the training data includes images tagged with labels for the classification of the images. A processor may prompt a user to define a framework for the classification. For an initial set of images within the training data, qualified human classifiers are prompted to locate the images within the framework and to tag the images with labels. The processor determines whether the tagged images have consistent labels, and, if so, the processor adds images to the training data. The processor may add the images by providing a visual guide, the visual guide including tagged images arranged according to their locations within the framework their labels, and prompting human classifiers to tag the additional images with labels for the classification, according to the visual guide.Type: GrantFiled: October 13, 2021Date of Patent: October 17, 2023Assignee: Landing AIInventors: Dongyan Wang, Gopi Prashanth Gopal, Andrew Yan-Tak Ng, Karthikeyan Thiruppathisamy Nathillvar, Rustam Hashimov, Pingyang He, Dillon Anthony Laird, Yiwen Rong, Alejandro Betancourt, Sanjeev Satheesh, Yu Qing Zhou

Patent number: 11412657Abstract: Systems and methods are disclosed herein for optimizing harvester yield. In an embodiment, a controller receives a pre-harvest image from a front-facing camera of a harvester. The controller inputs the pre-harvest image into a model, and receives as output from the model a predicted harvest yield. The controller receives, from an interior camera of the harvester, a post-harvest image including the plants as harvested. The controller inputs the post-harvest image into a second model and receives, as output, an actual harvest yield of the plants as-harvested. The controller determines that the predicted harvest yield does not match the actual harvest yield, and outputs a control signal.Type: GrantFiled: December 12, 2019Date of Patent: August 16, 2022Inventors: Dongyan Wang, Andrew Yan-Tak Ng, Yiwen Rong, Greg Frederick Diamos, Bo Tan, Beom Sik Kim, Timothy Viatcheslavovich Rosenflanz, Kai Yang, Tian Wu

Patent number: 11189601Abstract: A mounting substrate has a patterned metal layer defining a plurality of top metal bond pads for bonding to bottom metal bond pads of LED dies. A solder mask layer is formed over the mounting substrate, where the mask has openings that expose the top metal bond pads and protects metal traces on the substrate. The mask layer is a highly reflective white paint. The exposed top metal bond pads are then wetted with solder. The LED dies' bottom metal bond pads are then soldered to the exposed top metal bond pads, such that the mask layer surrounds each LED die to reflect light. A reflective ring is affixed to the substrate to surround the LED dies. A viscous phosphor material then partially fills the ring and is cured. All downward light by the LED dies and phosphor is reflected upward by the ring and solder mask layer.Type: GrantFiled: February 5, 2019Date of Patent: November 30, 2021Assignee: Lumileds LLCInventors: Yiwen Rong, Frederic Stephane Diana, Ting Zhu, Gregory Guth
