Publication number: 20240169140Abstract: Methods, systems, apparatuses, devices, and computer program products are described. A group-based communication system may support automatic layout updates for a document space. If a user adds an object into the document space, the system may generate a card representing the object. The card may include a link to a resource external to the document space and a preview image for the object, where the preview image may be rendered based on unfurling the link. The system may update a layout of the document space to include the generated card and may send, for display in a user interface (UI) of a user device, the updated layout. In some examples, a user may select to reposition the card within the UI (e.g., by dragging-and-dropping the card within the document space). The system may further update the layout of the document space based on the repositioning of the card.Type: ApplicationFiled: November 21, 2022Publication date: May 23, 2024Inventors: Greg Joseph Gauthier, Aubrey Elizabeth Logan-Terry, James Barnes, Michael Hahn

Patent number: 11622910Abstract: A ball roller assembly may include an inner sphere that is constructed from a thermal-sensitive material. The ball roller assembly may also include an outer sphere that is constructed from a thermal-conductive material. The inner sphere may be disposed within the outer sphere and thermal transfer may occur between the inner sphere, the outer sphere, and a user of the ball roller assembly. The ball roller assembly may further include a housing constructed from a thermal-insulative material, and the outer sphere and the inner sphere may be disposed within the housing. The inner sphere may be selectively removable from the outer sphere and the outer sphere may be selectively removable from the housing.Type: GrantFiled: August 5, 2018Date of Patent: April 11, 2023Assignee: KT Health, LLCInventors: Jeremy John Newns, Greg Hahn

Patent number: 11542942Abstract: In some examples, a scroll compressor may include an orbiting scroll and a fixed scroll having spiral involutes intermeshed together. A slider block may be disposed on the eccentric portion of a main shaft and the slider block may be attached to a compliant counterweight. The counterweight may be supported by a counterweight guide plate that is supported by the main shaft. The counterweight guide plate may also have an arm securing a top portion of the counterweight thereby securing the slider block. In some implementations, a spring assembly may be provided between an outer edge of the counterweight and the counterweight guide plate. These components may, in part, allow for a constant involute contact between the fixed scroll and orbiting scroll involutes at high speeds thereby achieving high compression efficiency.Type: GrantFiled: July 7, 2020Date of Patent: January 3, 2023Assignee: HITACHI-JOHNSON CONTROLS AIR CONDITIONING, INC.Inventors: Greg Hahn, Joe Hill, Jianhui Peng, Gene Fields

Patent number: 6966759Abstract: A compressor diagnostic system incorporates a control which receives a plurality of data streams about various operational features of the compressor. As an example, both temperature and pressure of the suction and discharge refrigerant are taken and sent to the control. Moreover, information with regard to the power being supplied to the motor is taken and stored. All of this information is utilized at a control which compares the information to expected values and determines a fault based upon the evaluation. Moreover, in another feature of this invention, much of this data is stored, and maintained at the compressor. In the event of a compressor failure, this stored information will provide a maintenance worker with a good indication of why the compressor failed.Type: GrantFiled: December 9, 2004Date of Patent: November 22, 2005Assignee: Scroll TechnologiesInventors: Greg Hahn, Zili Sun, Carlos Zamudio, Jason Hugenroth, Thomas Barito, James W.

Patent number: 6964558Abstract: Low voltage electrical power is supplied to a diagnostic control device in a sealed compressor. Electrical power is tapped from a high voltage power line and transformed to low voltage power that in turn operates the diagnostic control device. The diagnostic control device and the electric voltage transforming system are housed within the sealed compressor shell, thus eliminating the need for additional openings in the compressor shell. Other low voltage devices can be powered in this way.Type: GrantFiled: August 29, 2003Date of Patent: November 15, 2005Assignee: Scroll TechnologiesInventors: Greg Hahn, Zili Sun, Carlos Zamudio, Jason Hugenroth, Thomas Barito, James W.

Patent number: 6599109Abstract: A number of improvements increase the flow of lubricant within a scroll compressor. A centrifugal oil separator is mounted on the discharge port to remove oil from the refrigerant. The oil is returned through a leak path such that the oil can easily return back to a suction pressure chamber. The leak path is preferably upstream of a check valve. Thus, at shutdown, the leak path will not allow upstream components to also equalize in pressure with the suction pressure chamber of the compressor. Further, a number of embodiments include ways of resisting flow of refrigerant through the leak path, while still allowing oil flow. A number of valve elements are described which perform this function. Alternatively, labyrinth flow paths, or positioning of the return paths such that it will be closed when the compressor is shut down are disclosed.Type: GrantFiled: October 2, 2001Date of Patent: July 29, 2003Assignee: Scroll TechnologiesInventors: Carlos Zamudio, Zili Sun, Jason Hugenroth, Greg Hahn, Thomas Barito, James W.

Patent number: 6547543Abstract: A scroll compressor has a non-orbiting scroll axially secured within an end cap without being mechanically fixed to the end cap. The compressor is of the sort wherein the back pressure chamber is defined behind the orbiting scroll. In one embodiment a spring biases the non-orbiting scroll toward the orbiting scroll. In other embodiments the non-orbiting scroll is force fit within the end cap.Type: GrantFiled: June 28, 2002Date of Patent: April 15, 2003Assignee: Scroll TechnologiesInventors: Zili Sun, Greg Hahn
