Patent number: 11954124Abstract: A follower system and a leader system store records for a plurality of users. Each of the follower system and the leader system stores at least a record for a user. Each of the follower system and the leader system stores a private log and a public log. The public log is periodically synchronized across the follower system and the leader system. The private log of each system is maintained independent of the other system. The follower system transmits information stored in the public logs to the leader system for synchronizing the public logs of the follower system and the leader system in response to updating the public logs with information describing the second set of transactions.Type: GrantFiled: April 18, 2022Date of Patent: April 9, 2024Assignee: WEALTHFRONT CORPORATIONInventors: Austin Douglas McKee, Julien Daniel Wetterwald

Patent number: 10683617Abstract: A wall covering, a method of producing it and a method of covering a wall. The wall covering comprises a planar substrate, such as a nonwoven base substrate, having a front, and a back facing opposite the front. There is a barrier layer on the back of the substrate and an adhesive layer superimposed on the barrier layer. The adhesive layer comprises a first polymer component, a second polymer component, the first polymer component being a non crosslinked polymer and said second polymer component being a crosslinked polymer exhibiting properties of superabsorbency. The adhesive exhibits when exposed to water, a strength sufficient for binding to a wall substrate and a glide resistance low enough for allowing repositioning of the wall cover by sliding the wallcover on the wall without having to lift it up over a period of time of at least 5 minutes.Type: GrantFiled: May 15, 2015Date of Patent: June 16, 2020Assignee: Ahlstrom-Munksjö OyjInventors: Douglas McKee Benton, Erkki Laiti, Hootan Farhat, Noah Tremblay, Madeline Vara, Xinhua Li, Olivier Schueller

Patent number: 9345194Abstract: A farm vehicle includes a crop gathering mechanism to convey harvested crop material to a crop flow path passing internally through at least part of the vehicle. The vehicle includes a vehicle data bus and a plurality of control modules operatively connected to the vehicle data bus and configured to monitor information on the vehicle data bus and to act according to such information. An electronic operator module is configured to monitor the states of operator controls and to broadcast information on the vehicle data bus specifying such states. Additionally, video cameras positioned within the vehicle face the crop flow path and are operably connected to a graphic display. A graphic display control module includes a processor configured to control the display of images on the graphic display for selective display of images from the video cameras based upon information from the vehicle data bus.Type: GrantFiled: September 30, 2009Date of Patent: May 24, 2016Assignee: CNH Industrial America LLCInventors: Jay David Schroeder, Daniel Lynn Renaud, John Michael King, Kevin Douglas McKee

Patent number: 9162280Abstract: A hybrid ceramic/sand casting method of manufacturing a metal part. The method is especially suitable for manufacturing engine cylinder blocks or cylinder head, which have very small internal passages or other very small internal features. These parts are formed using a hybrid core having at least one ceramic section and at least one sand section, with the ceramic section being used to create the internal feature. A mold cavity is created for the part, and the hybrid core is positioned in the mold. Molten metal is introduced into the mold, and after the metal cools, the core is removed, thereby forming the part with the internal feature.Type: GrantFiled: July 23, 2013Date of Patent: October 20, 2015Assignee: SOUTHWEST RESEARCH INSTITUTEInventors: Barry E. Westmoreland, Douglas A. McKee, Marc C. Megel, Mark A. Tussing, Thomas E. Reinhart, David P. Branyon

Patent number: 8899207Abstract: A cylinder head for an engine is provided comprising a monolithic structure forming an upper deck, a fire deck, at least one coolant jacket and a cavity to accommodate a fuel injector or an ignitor therein, the cavity defined by a wall connecting the fire deck with the upper deck. The wall connecting the fire deck with the upper deck, as well as other features of the cylinder head, are preferably arranged to support the fire deck against a deflection thereof by transmitting a mechanical load introduced on a flame face of the fire deck to the upper deck. A method of increasing the stiffness of the cylinder head is also provided.Type: GrantFiled: October 14, 2009Date of Patent: December 2, 2014Assignee: Southwest Research InstituteInventors: Marc C.

Patent number: 8267148Abstract: A hybrid ceramic/sand casting method of manufacturing a metal part. The method is especially suitable for parts having one or more very small internal gaps, such as might occur with a linear passage or round opening. These parts are formed using a hybrid core having at least one ceramic section and at least one sand section, with the ceramic section being used to create the internal gap.
