  • Patent number: 12037064
    Abstract: An articulated chain assembly includes standard links, a master link, and pins pivotably coupling together the standard links and master link. The master link includes a first half link and a second half link, and bolt holes extending through the first half link and the second half link. A first bolt is within a first one of the bolt holes and has a necked-down bolt shank defining a lesser necked-down axial length. A second bolt is within a second one of the bolt holes and includes a necked-down bolt shank defining a greater necked-down axial length. The first bolt and second bolt may have unequal full axial lengths.

  • Publication number: 20240078189
    Abstract: The present disclosure provides systems, methods, devices, and computer program products for cache eviction enforcement and multi-tenant distributed cache architectures and operations. Systems, methods, devices, and computer program products may access a slab of a multi-tenant caching system, perform an eviction review by sequentially reaping through the slab, based on the class size, flag a first cache item by the eviction review based on a header of the first cache item, wherein the header comprises a prefix indicative of an expiry time, confirm expiration of the first cache item via a lock and lookup operation, and evict the first cache item from the slab. Significant optimization and efficiency benefits may be realized through the slab organization, cache architectures, and operations discussed herein.

  • Patent number: 11868959
    Abstract: Examples provide an item storage cart for verifying correct item placement into containers on the item storage cart. A cart manager component outputs planogram data identifying a location of a selected item. Weight data generated by one or more weight sensors associated with the set of item storage containers is analyzed to verify whether a correct item is placed in a given storage container on the cart and/or verify a selected item is placed into a correct storage container. The cart manager component determines if an unselected item is removed from a storage container and/or if an unselected item is added to a storage container. A notification is output if an incorrect item is added to a cart, an incorrect item is removed from the cart, an item is added to the wrong container or removed from the wrong container.

  • Publication number: 20230394727
    Abstract: Systems and techniques for dynamic color adjustment in augmented reality are described herein. An image of a user may be obtained from an imaging sensor. A variation between a baseline color calibration and the image of the user may be calculated. A transformation algorithm may be applied to variables of a color of an augmented reality overlay based on the variation to generate a color adjusted augmented reality overlay.

  • Patent number: 11820447
    Abstract: A shroud for a track shoe grouser protector includes an elongate shroud body having weld holes formed in a first shroud leg and a second shroud leg attached to a base in the elongate shroud body. The shroud may have a fore to aft profile having the form of a flat-crowned arch with the shroud legs flared outward to form a grouser opening for positioning the shroud upon a track shoe grouser in a ground-engaging track system. An inventory of shrouds includes long shrouds and short shrouds positionable in a plurality of different assembly combinations to shield grousers in track shoes having a range of sizes.

  • Publication number: 20220194495
    Abstract: An idler assembly includes a cylindrical hub defining an axis of rotation, a radial direction, and a circumferential direction. A stepped circumferential surface of the cylindrical hub has a first radially inner face, and a radially outer cylindrical face. Mounting holes extend radially into the radially outer cylindrical face. A first idler segment is attached to the cylindrical hub, and includes an at least partially flat body having a first planar chain link contacting surface. The cylindrical hub has a first set of metallurgical properties that is different than the second set of metallurgical properties of the first idler segment.

  • Patent number: 11025065
    Abstract: The present invention relates to a method of monitoring oscillations that are liable to interact in an electrical power network, in dependence on measurement of AC waveforms in the electrical power network. The method comprises receiving first waveform data corresponding to an electrical quantity in each phase of at least two phases of three-phase AC waveforms at a location in the electrical power network. The method further comprises applying a transformation to the first waveform data to provide therefrom second waveform data corresponding to an electrical quantity at the location in a single phase representation, the second waveform data depending on the at least two phases.
