  • Patent number: 11932775
    Abstract: A curable coating composition is provided having multi-functionalized acrylic copolymer and silicone imine resin curing agents. The acrylic copolymer of the curable coating composition has, in polymerized form, epoxy functionalized groups and cure compatibility groups and the silicone imine forms an amino-functional silicone in the presence of water. The coating compositions are useful in the field of superior weatherable and durable coatings and are useful to replace isocyanate-containing polyurethane based coatings. Also provided are coated articles produced from the curable composition.

  • Publication number: 20240069874
    Abstract: Methods and apparatuses are described for intelligent imputation of missing data in a machine learning (ML) dataset comprised of a plurality of features. Each feature includes a plurality of values, where at least a portion of the values for one or more features are missing. A server analyzes the ML dataset to generate characteristics of the missing values in the ML dataset. The server selects an imputation algorithm for filling in the missing values based upon the identified characteristics. The server determines a computing environment in which the imputation algorithm is executed based upon one or more of a size of the ML dataset or the selected algorithm. The server generates code that comprises instructions for executing the imputation algorithm on the ML dataset in the computing environment. The server integrates the code into an ML platform that executes the code to assign replacement values to the missing values.

  • Publication number: 20210404231
    Abstract: A hinge for a door or window has a door or window and a frame. The hinge has a first and a second hinge leaf pivotably connectable to each other. The first hinge leaf is connectable to the door/window or frame. The second hinge leaf is adjustably connectable to a base in turn connectable to the other of said door/window or frame. The second hinge leaf extends from the base in a first direction and the hinge comprises an adjustment mechanism with a cam and follower configured so that rotating the cam moves the second hinge leaf, relative to the base, in the first direction.

  • Publication number: 20090140382
    Abstract: A polysilicon silicide electric fuse device, comprising: a substrate; a semiconductor material layer disposed on said substrate, said semiconductor material layer includes lead-out areas of the same doping type at both ends, and an intermediate area of non-doping or having dopant concentration lower than those of said lead-out areas at both ends; and one or more burn-out areas is/are provided in said intermediate area; and a metal silicide layer is provided on said semiconductor material layer. Through the application of said polysilicon silicide electric fuse device, the burning out of said fuse device is thus controlled to within said intermediate area of no doping or light doping, hereby increasing the mean value and reducing distribution area of electrical resistance after burning out of a fuse, and alleviating the overheating of surrounding areas as caused by a current during the burning out of a fuse.
