  • Patent number: 12584500
    Abstract: Integrally geared centrifugal compressor systems are described that include eccentric cartridges that house bearings and seals to maintain rotor concentricity for a variety of pinons integrated in a fixed gearbox design to provide multiple impeller speeds with a single gearbox design. In an aspect, a system includes, but is not limited to, a pinion configured to be rotated by a bull gear about a rotational axis; a rotor coupled to the pinion; and an eccentric cartridge configured to house a bearing assembly through which the rotor extends to support rotation of the rotor, the eccentric cartridge having an outer surface and an inner surface, wherein the inner surface is eccentric relative to the outer surface to align the rotational axis with a center axis of the bearing assembly.

  • Publication number: 20250321808
    Abstract: A method for performing computer-based tasks using computer applications and a machine learning model (MLM) includes identifying, within input data, a set of requests for performing corresponding computer-based tasks, utilizing the MLM. This identification process includes determining a computer application for executing the request and determining a programming instruction. The programming instruction includes a call to the computer application using an application programming interface (API) associated with the computer application. For the set of requests, the method includes generating computer instructions outlining a sequence for executing a set of programming instructions. Each instruction corresponds to the determined programming instruction and is configured with the associated API to accept input parameters generated from identified information within the input data, output parameters from the execution of any of the set of programming instructions, or a combination thereof.

  • Publication number: 20250272068
    Abstract: The computer-implemented method for processing text data includes receiving text data, receiving a set of descriptions for editing the text data, and generating a set of functions corresponding to the set of descriptions. The process of generating the set of functions for each description in the set of descriptions includes generating a computer code representing a function from the set of functions for processing the text data using a machine learning language model. Further, the method includes applying each one of the set of functions to the text data to generate output text data.

  • Patent number: 11941345
    Abstract: A computer-implemented process is programmed to process a source input, determine text enhancements, and present the text enhancements to apply to the sentences dictated from the source input. A text processor may use machine-learning models to process an audio input to generate sentences in a presentable format. An audio input can be processed by an automatic speech recognition model to generate electronic text. The electronic text may be used to generate sentence structures using a normalization model. A comprehension model may be used to identify instructions associated with the sentence structures and generate sentences based on the instructions and the sentence structures. An enhancement model may be used to identify enhancements to apply to the sentences. The enhancements may be presented alongside sentences generated by the comprehension model to provide the user an option to select either the enhancements or the sentences.
