Patent number: 11976730Abstract: Systems and assemblies are provided for sealing an interface between a cylinder and a manifold corresponding to the cylinder. The cylinder comprises at least one port. A manifold interface is arranged adjacent to the at least one port. A seal is located inside of a circumferential pocket, wherein the circumferential pocket comprises at least a portion of the manifold interface. A spring is configured to preload the seal radially inward so that the seal stays in contact with the outer surface of the cylinder.Type: GrantFiled: November 15, 2021Date of Patent: May 7, 2024Assignee: Mainspring Energy, Inc.Inventors: Kevin Walters, Michael Buchman, Cameron Wylie, Kaley Boyce, John Laporga, David DeGraaff

Patent number: 11562360Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for conducting cardless payment transactions. One of the methods includes receiving, in association with a payment transaction, a message from a customer device that includes data from an optical scan of a code displayed at a merchant point-of-sale. A request to authorize a payment for the payment transaction is received from a merchant computer. Customer and merchant accounts are identified and payment data previously associated with the customer account is accessed. The payment is authorized using the payment data, and notification of authorization is sent to the merchant device or customer device.Type: GrantFiled: April 29, 2022Date of Patent: January 24, 2023Assignee: Block, Inc.Inventors: Daniel Neighman, Eric Firestone, Daniel Spencer, Cameron Walters, Sophia Huang

Patent number: 11455633Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for conducting cardless payment transactions. One of the methods includes receiving from a first device of a first user a first message requesting a payment transaction with a second user. Using an identifier of the second user provided by the first device, sending a second message to a second device of the second user requesting approval of the transaction, wherein the second message includes an approval code. A third message is received from the second device. If the third message includes the provided approval code and is received within a threshold amount of time, the payment transaction is processed using account information received in the first message.Type: GrantFiled: July 31, 2019Date of Patent: September 27, 2022Assignee: Block, Inc.Inventors: Daniel Neighman, Eric Firestone, Daniel Spencer, Cameron Walters, Sophia Huang

Patent number: 10438202Abstract: Processing cardless payment transactions is described. In an example, a server system can receive a message from a mobile device of a user that includes a code identifying a merchant and can verify the identities of the merchant and the user based at least in part on account data stored in association with the server system. The server system can provide, to a merchant computer of the merchant, user information associated with the user account and can receive from the merchant computer, a request to authorize the cardless payment transaction. The server system can obtain authorization for the cardless payment transaction using account information associated with the merchant account and/or the user account, and can provide, to the merchant computer, notification of the authorization of the cardless payment transaction.Type: GrantFiled: November 21, 2014Date of Patent: October 8, 2019Assignee: Square, Inc.Inventors: Daniel Neighman, Eric Firestone, Daniel Spencer, Cameron Walters, Sophia Huang

Patent number: 9604322Abstract: Method of assembling a rotor assembly of a gas turbine engine having a plurality of components. The method comprises in one aspect calculating the bending forces due to the mass distribution along the rotor. In another aspect, an optimization routine iterates different rotor arrangements, comparing the calculated bending moments to determine a set of component positions that minimizes the bending forces. In another aspect, mass corrections are optimized to balance the rotor assembly.Type: GrantFiled: December 11, 2013Date of Patent: March 28, 2017Assignee: PRATT & WHITNEY CANADA CORP.Inventor: Cameron Walters
