Patent number: 11536507Abstract: A chilled water distribution system includes a chilled water loop in fluid communication with a plurality of buildings and also in fluid communication with a plurality of chiller stations. A monitoring and control system communicates with one of the chiller stations, hereinafter referred to as a “controlled” chiller station because it is configured with one or more variable frequency drives that are controlled by the monitoring and control system to modulate the speed of at least one chiller station component such as, but not limited to, a pump or a fan. By way of this modulation process, a differential pressure of the chilled water loop may be maintained in a “sweet spot” so as to optimize chiller station output while minimizing chiller station energy consumption.Type: GrantFiled: December 16, 2019Date of Patent: December 27, 2022Assignee: Optimum Energy, LLCInventors: Ben Erpelding, Ian Dempster

Patent number: 11473796Abstract: A controller is configured to exchange information with a building automation system and includes various executable programs for determining a real time operating efficiency, simulating a predicted or theoretical operating efficiency, comparing the same, and then adjusting one or more operating parameters on equipment utilized by a building's HVAC system. The controller operates to adjust an operating efficiency of the HVAC system. An adjustment module utilized by the controller may modify the HVAC equipment parameters based on the likelihood that various HVAC equipment operates in parallel and on-line near its natural operating curve. In addition, the adjustment module may include a self-learning aspect that permits the controller to more efficiently make similar, future adjustments as needed.Type: GrantFiled: August 15, 2019Date of Patent: October 18, 2022Assignee: Optimum Energy LLCInventors: Ian Dempster, Ben Erpelding, James Hanna

Patent number: 10556239Abstract: An example method for operating a plant, which has at least one assembly with a rotating surface that wears to an increasing extent during the operation of the plant, may involve evaluating a wear state of the rotating surface of the assembly. Based on the wear state of the rotating surface, a manner in which the plant is operated may be modified to prolong the running time of the assembly until, for instance, a next-scheduled service or maintenance interval. The modified manner of operating the plant may be adapted to the wear state of the rotating surface. Several examples of such modifications include changing a quantity of water sprayed onto material to be comminuted, changing a quantity of grinding additive added to material to be comminuted, and/or changing a contact pressure of a grinding roll of the assembly.Type: GrantFiled: September 29, 2014Date of Patent: February 11, 2020Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS AGInventors: Reinhard Giesemann, Richard Erpelding, Uwe Bendig, Dirk Dilly, Dirk Schefer

Patent number: 10497000Abstract: In one embodiment, a point of return device can be configured to gather information related to a return request and a returning customer. Upon providing the information to an authorization server, the server can identify historical transaction data of the returning customer from data stored in a repository. Based on the historical transaction data and on the return request, the authorization server determines a return authorization decision based on an item-level return policy, another decision based on customer-specific return privileges, and optionally, another authorization decision based on registry-related return privileges. Upon processing the return request based on a selected return authorization decision, data representative of the processed return request is optionally stored in the repository to update the previously identified customer transaction data.Type: GrantFiled: May 10, 2017Date of Patent: December 3, 2019Assignee: TARGET BRANDS, INC.Inventors: David Barstad, Thomas William Branham, Julie Lynne Wegmiller, Jamie Ann Person, Lara Erpelding, Jayachandran Chandrashekaran, Koteswara R.
