Patent number: 11954379Abstract: The location of a printing device is determined. Environmental conditions in which the printing device operated when printing a print job are determined based on the determined location. An environmental adjustment factor for the printing device is determined based on the determined environmental conditions. A predicted print material usage of the printing device in printing the print job is adjusted based on the determined environmental adjustment factor.Type: GrantFiled: May 26, 2020Date of Patent: April 9, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jeffrey H.

Patent number: 11927909Abstract: An image forming apparatus includes a development cartridge having a developing roller. A coupler for the image forming apparatus includes a shaft and a coupling structure to rotate the developing roller. The coupling structure is disposed at an end part of the shaft, is movable along an axial direction of the shaft and coupleable with another coupling structure of a print engine of the image forming apparatus. The coupling structure includes a body, a magnet disposed in the body to cause the coupling structure to be attracted to the another coupling structure so that the coupling structure is aligned with the another coupling structure, and a plurality of protrusions which protrude from the body in the axial direction to engage with the another coupling structure, the plurality of protrusions having at least one side with an inclined face.Type: GrantFiled: September 28, 2020Date of Patent: March 12, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Elizabeth A. Swanson, Gabriel S. McDaniel, Jeffrey H. Luke

Patent number: 11927905Abstract: In response to detecting that a remaining supply of print material of a first cartridge has reached a first threshold, a printing device transmits a request. In response to detecting that a second cartridge has replaced the first cartridge, the printing device determines whether the remaining supply had reached a second threshold and whether a token permitting usage of the second cartridge was received responsive to the request. In response to determining that the remaining supply had reached the second threshold and that the token was received, the printing device prints with print material from the second cartridge.Type: GrantFiled: May 26, 2020Date of Patent: March 12, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jeffrey H. Luke, Gabriel S. McDaniel, Scott K Hymas

Publication number: 20240070421Abstract: The number of days until a consumable item of a printing device reaches end of life is predicted based on a usage scenario of the printing device. An expected fulfillment time period is subtracted from the predicted number of days to determine a number of days until a fulfillment event occurs. A threshold remaining life of the consumable item is correlated with the number of days until the fulfillment event occurs. That the remaining life of the consumable item has reached the threshold remaining life is detected, and fulfillment of a replacement consumable item to replace the consumable item is responsively initiated.Type: ApplicationFiled: January 15, 2021Publication date: February 29, 2024Inventors: Scott K. Hymas, Jeffrey H. Luke, Gabriel S. McDaniel

Patent number: 7507274Abstract: The disclosed invention relates to a process and apparatus for separating a first fluid from a fluid mixture comprising the first fluid. The process comprises: (A) flowing the fluid mixture into a microchannel separator in contact with a sorption medium, the fluid mixture being maintained in the microchannel separator until at least part of the first fluid is sorbed by the sorption medium, removing non-sorbed parts of the fluid mixture from the microchannel separator; and (B) desorbing first fluid from the sorption medium and removing desorbed first fluid from the microchannel separator. The process and apparatus are suitable for separating nitrogen or methane from a fluid mixture comprising nitrogen and methane. The process and apparatus may be used for rejecting nitrogen in the upgrading of sub-quality methane.Type: GrantFiled: March 2, 2006Date of Patent: March 24, 2009Assignee: Velocys, Inc.Inventors: Anna Lee Tonkovich, Steven T. Perry, Ravi Arora, Dongming Qiu, Michael Jay Lamont, Deanna Burwell, Terence Andrew Dritz, Jeffrey S. McDaniel, William A. Rogers, Jr., Laura J. Silva, Daniel J. Weidert, Wayne W. Simmons, G.
