Publication number: 20250093822Abstract: A multi-chain measurement circuit is disclosed. The measurement circuit includes first and second chains of serially-connected buffer circuits coupled in parallel, each of which propagates an input signal. A set of storage circuits is configured to store logic values generated by the first and second sets of buffer circuits in response to the transitioning of a clock signal. The logic values stored in the storage circuits result in a digital value indicative of a total number of serially-connected storage circuits through which the input signal has propagated at the time of the transition of the operating clock signal.Type: ApplicationFiled: November 21, 2024Publication date: March 20, 2025Inventors: Bo Zhao, Joao Pedro da Silva Cerqueira, Pangjie Xu, Steven Lu

Patent number: 12234003Abstract: A device for supporting a propulsor on a marine vessel. The device includes a base that is fixable to the marine vessel and a pivot arm for coupling the propulsor to the base. An actuator is configured to pivot the pivot arm relative to the base into and between a retracted position and a deployed position. A fastener is engageable to couple the actuator to the pivot arm, where when the fastener is engaged the pivot arm is prevented from pivoting other than by the actuator, and where applying a predetermined force on the pivot arm disengages the fastener to allow the pivot arm to pivot other than by the actuator.Type: GrantFiled: September 8, 2023Date of Patent: February 25, 2025Assignee: Brunswick CorporationInventors: Jeremy J. Kraus, Andres Perdomo Tornbaum, Tom Geng, Steven Lu, Matthew Z. Seta, Keith W. Schmidt, James E. Erickson, Ronald L. Hall

Patent number: 12221618Abstract: A pH-modulating poly(glycerol sebacate) composition includes poly(glycerol sebacate) and at least one pH-modulating agent associated with the poly(glycerol sebacate). A process of making a pH-modulating poly(glycerol sebacate) composition includes forming a poly(glycerol sebacate) by a water-mediated reaction from glycerol and sebacic acid and associating at least one pH-modulating agent with the poly(glycerol sebacate). A process of modulating a pH of a buffered aqueous solution includes placing a pH-modulating poly(glycerol sebacate) composition in a buffered aqueous solution. The pH-modulating agent is released into the buffered aqueous solution during degradation of the poly(glycerol sebacate) to reduce a decrease in pH of the buffered aqueous solution caused by degradation of the poly(glycerol sebacate).Type: GrantFiled: August 18, 2021Date of Patent: February 11, 2025Assignee: THE SECANT GROUP, LLCInventors: Peter D.

Patent number: 11932369Abstract: A device for coupling a propulsor to a marine vessel. The device includes a mounting bracket configured for attachment to the marine vessel. A support frame has a carriage and is configured for the propulsor to be coupled thereto, where the carriage is configured to slidably engage with the mounting bracket into a fixed position. A member is manually engageable to prevent the carriage from sliding out of the fixed position. The propulsor is coupled to the marine vessel by sliding the carriage into the fixed position and engaging the member, where the propulsor is operable to propel the marine vessel in water when the carriage is in the fixed position, and where the propulsor is configured for decoupling from the marine vessel by disengaging the member and sliding the carriage out of engagement with the mounting bracket.Type: GrantFiled: July 16, 2021Date of Patent: March 19, 2024Assignee: Brunswick CorporationInventors: Andres Perdomo Tornbaum, Tom Geng, Steven Lu, Matthew Z.
