  • Publication number: 20250092635
    Abstract: A fatigue life optimized modular bucket assembly for a work machine and a method of manufacturing thereof are disclosed. The bucket assembly includes a bucket core having a pair of side sections, a continuous wrapper, a supporting element, and a receptacle; and an extension module having a pair of side bars, a guard module, an edge module, and, optionally, a set of extension plates. The method includes prebuilding the bucket core, receiving an order, providing parts for the extension module, and assembling the bucket core and the extension module parts. The bucket assembly may include universal and customizable components without exhibiting reduction to fatigue life commonly associated with weld seams.

  • Patent number: 11734433
    Abstract: A method and system for remediating vulnerable code libraries, including open source libraries, in a software application. An application, that uses code libraries, and information regarding known library vulnerabilities are received, then it is determined if one or more libraries in the application are vulnerable based upon the information. For each of the one or more vulnerable libraries, a library version that minimizes risk is determined. The determined library version is incorporated into the application to form a test application, and an application test is performed on the test application. If an application test score on the test application is below a predetermined threshold, the determined library version is incorporated into a final application precursor. A final application can be determined from the final application precursor for each of the one or more vulnerable libraries.

  • Patent number: 10465359
    Abstract: An implement system includes a linkage and a bucket coupled with the linkage and movable between a dump position and a racked position. The bucket has a compound back section that forms a profile having a basin shape to assist in distributing material within the back section when the bucket is curled, and nesting the bucket close to the linkage. Related methodology is disclosed.
