Patent number: 12061970Abstract: Systems and methods of the present disclosure may receive, from a user computing device, a user-provided data record query including a natural language request for information associated with one or more data sources. User persona attributes of the user may be determined, such as a user role or security parameters or both. Based on the user persona attributes a context query may be generated to obtain context attributes associated with the user-provided query. The natural language request and the context attributes are input into the model orchestration large language model (LLM) to output instructions to machine learning (ML) agents based on the context attributes. The ML agents output responses associated with the user-provided data record query based on the instructions, and the responses are input into the model orchestration LLM to output to the user computing device a natural language response based on the context attributes.Type: GrantFiled: October 6, 2023Date of Patent: August 13, 2024Assignee: Broadridge Financial Solutions, Inc.Inventors: Joseph Lo, Fitim Kryeziu, James Kwiatkowski

Patent number: 9556875Abstract: A centrifugal compressor assembly for compressing refrigerant in a 250-ton capacity or larger chiller system comprising a motor, preferably a compact, high energy density motor or permanent magnet motor, for driving a shaft at a range of sustained operating speeds under the control of a variable speed drive. Another embodiment of the centrifugal compressor assembly comprises a mixed flow impeller and a vaneless diffuser sized such that a final stage compressor operates with an optimal specific speed range for targeted combinations of head and capacity, while a non-final stage compressor operates above the optimum specific speed of the final stage compressor. Another embodiment of the centrifugal compressor assembly comprises an integrated inlet flow conditioning assembly to condition flow of refrigerant into an impeller to achieve a target approximately constant angle swirl distribution with minimal guide vane turning.Type: GrantFiled: January 13, 2014Date of Patent: January 31, 2017Assignee: TRANE INTERNATIONAL INC.Inventors: Paul F. Haley, Dennis R. Dorman, Frederic Byron Hamm, Jr., David M. Foye, James A. Kwiatkowski, Rick T. James, Randall L. Janssen, William J. Plzak

Publication number: 20150013360Abstract: A coaxial economizer for use in a chiller system comprising an inner housing and an outer housing having a common longitudinal axis. The outer housing has an inlet for receiving a fluid from a upstream compressor stage of a multistage compressor and an outlet for conveying a fluid to a downstream compressor stage of a multistage compressor. A flow chamber forms a fluid flow path about the inner housing. A flash chamber is coterminous with the flow chamber and flashes fluid in a liquid state to a gas state. A flow passage between said flash chamber and the flow chamber for conveying a flashed gas from the flash chamber to the flow chamber; wherein the flashed gas conveyed from the flash chamber and the fluid received from the inlet of the outer housing mix along the fluid flow path toward the outlet of the outer housing.Type: ApplicationFiled: September 30, 2014Publication date: January 15, 2015Inventors: Paul F. Haley, Dennis R. Dorman, Frederic Byron Hamm, David M. Foye, James A. Kwiatkowski, Rick T. James, Randall L. Janssen, William J. Plzak

Publication number: 20070201995Abstract: A refrigerant motor/compressor employs both a serviceable shaft-grounding device and a ceramic coating to protect a rolling element bearing that could otherwise be damaged by high frequency induced common mode voltage and current originating from an inverter that includes a plurality of IGBTs (insulate gate bipolar transistors). The shaft-grounding device includes a stranded copper wire brush that rides against an axial end of the shaft and a high frequency stranded grounding wire that conducts the induced current away from the shaft. The shaft-grounding device is sized and positioned so that it can be momentarily removed for inspection without having to evacuate the refrigerant. The ceramic coating provides an electrical insulating surface on a bearing bracket and other parts that support the bearing. The coating comprises titanium dioxide and aluminum oxide to provide a surface that is sufficiently hard and tough to resist damage during assembly, thereby maintaining the coating's integrity.Type: ApplicationFiled: February 24, 2006Publication date: August 30, 2007Inventors: Michael Harstad, Joel Duga, Gregory Fiegen, Brian Sullivan, James Kwiatkowski, Peter Kotlarek, Richard Heiden
