Patent number: 12004824Abstract: A modular energy system for use in a surgical environment includes a plurality of functional modules including at least an initial module, a functional module, and a terminal module. Each of the plurality of modules has a module control circuit, and a local data bus. An internal data bus is composed of a serial array of the local data busses of the modules. The local data bus may includes a communication switch, a first switch data path between the communication switch and the module control circuit, a second switch data path in communication with the communication switch, and a third switch data path in communication with the communication switch. The third switch data path of a module N is in communication with a second switch data path of a module N+1. The system further includes a termination unit in communication with the third data path of the terminal module.Type: GrantFiled: March 30, 2021Date of Patent: June 11, 2024Assignee: Cilag GmbH InternationalInventors: Daniel C. Herman, Joshua P. Morgan, Andrew W. Carroll, Jonathan T. Samuel, Joshua M. Henderson, James M. Vachon, Jeffrey L. Aldridge, Eitan T. Wiener

Patent number: 11998974Abstract: A casting core used in the manufacture of a cast engine component for a turbine engine, the cast engine component having a first area, a second area, a fluid passage wall separating the first area and the second area, and a connecting fluid passage extending through the fluid passage wall and interconnecting the first area and the second area. The connecting fluid passage having a turn with a radius (R). The casting core having a first core and a second core. The first core and the second core being defined by a set of geometric characteristics having a first minimum equivalent diameter (D1eqmin) of the first core and a second minimum equivalent diameter (D2eqmin) of the second core. A first flexible geometry factor (FGF1) being equal to: ( D ? 1 eq ? min D ? 2 eq ? min ) ? ( R D ? 2 eq ? min ) .Type: GrantFiled: August 30, 2022Date of Patent: June 4, 2024Assignee: General Electric CompanyInventors: Daniel Endecott Osgood, Zachary Daniel Webster, Craig Alan Gonyou, Daniel Lee Durstock, Kevin R. Feldmann, Kirk Douglas Gallier, William C. Herman, Nicholas Charles Gentilli

Patent number: 11963727Abstract: Mitigating a user interface display function of a modular energy system includes receiving formatted video data at a video data converter circuit, providing differential video signaling data to the display from the video data converter circuit, providing a copy of the differential video signaling data to a processor, and determining that the differential video signaling data is changing over time. Mitigating erroneous outputs from an isolated interface includes receiving a state of a first switch of a first footswitch coupled to a first comparator and a reference voltage coupled to the first comparator, receiving the state of the first switch coupled to the first duplicate comparator and the reference voltage coupled to the first duplicate comparator, comparing the output of the first comparator with the output of the first duplicate comparator, and determining activation or deactivation of a surgical instrument coupled to the controller based on the comparison.Type: GrantFiled: March 30, 2021Date of Patent: April 23, 2024Assignee: Cilag GmbH InternationalInventors: Joshua P. Morgan, Andrew W. Carroll, Jeffrey L. Aldridge, Joshua M. Henderson, James M. Vachon, Eitan T. Wiener, Daniel C. Herman, Jonathan T. Samuel, Jeffrey A. Bullock

Publication number: 20220313369Abstract: Various methods are disclosed. One method includes reading an RFID card that is associated with a surgical instrument when the RFID card is located proximal to an RFID reader and initiating a wireless pairing process with the surgical instrument by the header module. Another method includes receiving an accessory at an accessory port of a modular energy system, communicating via a flexible serial communication interface coupled between a processor and the accessory port, the flexible serial communication interface configured to support multiple communication protocols, and detecting, by a presence detection circuit coupled between the accessory port and the processor, presence of the accessory connected to the accessory port. Other methods include a flexible serial bus power configuration method for a modular energy system and a remote power control interface method for a modular energy system.Type: ApplicationFiled: March 30, 2021Publication date: October 6, 2022Inventors: Brendan J. Oberkircher, Cory G. Kimball, Matthew S. Corbin, Monica L. Z. Rivard, Joshua P. Morgan, Daniel C. Herman, Joshua M. Henderson, Andrew W. Carroll, Eitan T. Wiener, Jeffrey L. Aldridge
