Publication number: 20240395114Abstract: An electronic bingo gaming system enables the entertainment mechanisms in Class II gaming machines to mimic the look and feel of the Class III games on which those entertainment mechanisms are based. The system is constructed to minimize any wait times by players that commence a bingo game or join a bingo game already in progress. To create consistency in what players are hoping to see on their bingo cards, the bingo game may use a single interim prize pattern required to win an interim prize that is the same for all players.Type: ApplicationFiled: August 7, 2024Publication date: November 28, 2024Inventors: Keshav PITANI, Qiaofeng YANG, Brett GOTTIER, Thais JORDAN, Kellen DALE, David WELCH, Francois RINGUETTE

Publication number: 20240341422Abstract: A numismatic that can include embossed and debossed regions that are configured to allow the stable stacking of a series of numismatics, for the purpose of reducing plastic waste by providing storage modalities that preclude the need for plastic sleeve holders. The stackable numismatic may also include embossed and debossed formations that are coaxial, decorations, and/or script. Such stackable numismatics may be displayed within a balanced magnetic field of a decorative device.Type: ApplicationFiled: June 27, 2024Publication date: October 17, 2024Applicant: Asset Marketing Services, LLCInventors: William Gale, Robert Becka, David Welch, Bob Wilkie, Mike Esson, Peter Gu

Publication number: 20240291566Abstract: Consistent with the present disclosure, a transceiver is implemented as a photonic integrated circuit (PIC) that includes a transmitter and a receiver. A laser is also provided that provides light to a splitter, which supplies a first portion of the light to the transmitter and a second power of the light to the receiver. Semiconductor optical amplifiers (SOAs) are provided at one or more locations on the PIC. In one example, at least one SOA is provided in the transmitter so that the transmitted optical signal has a desired power, and at least another SOA is provided in the receiver so that the local oscillator signal has a desired power. In a further example, an SOA is provided in the receiver to boost the power of the received optical signal. Preferably, the transceiver, including the SOAs, is monolithically integrated on a substrate, such as a substrate including indium phosphide (InP). Moreover, the SOA can be readily controlled via a low voltage current source consuming minimal electrical power.Type: ApplicationFiled: December 29, 2023Publication date: August 29, 2024Applicant: Infinera CorporationInventors: Vikrant Lal, Peter Evans, David Welch, Mehrdad Ziari, Scott Corzine, Thomas Frost

Patent number: 12053064Abstract: A stackable form of a numismatic that includes a visible, centrally embedded magnet for the purpose of reducing plastic waste by providing storage modalities for such that preclude the need for plastic sleeve holders. The stackable magnetic numismatic may also include embossed and debossed formations, decorations, and/or script. Such stackable magnetic numismatics may be displayed within a balanced magnetic field of a decorative device.Type: GrantFiled: February 9, 2022Date of Patent: August 6, 2024Inventors: William Gale, Robert Becka, David Welch, Bob Wilkie, Mike Esson, Peter Gu

Patent number: 12054328Abstract: In a method of printing a product, a plate gap can be at least partially concealed, and the presence of any trap lines can be minimized. The background of each impression can be printed to include a gradient region along the leading and trailing edges of the background adjacent to the plate gap. An overprint ink/layer can be printed over the plate gap and at least a portion of the background gradient regions. The overprint ink/layer can be printed to include gradient regions along the leading and trailing edges of the overprint. The overlapping gradient regions of the background and of the overprint soften or obscure the appearance of any trap lines that would otherwise be more prominent in the overlapping areas.Type: GrantFiled: October 18, 2019Date of Patent: August 6, 2024Assignee: Printpack Illinois, Inc.Inventors: Stephen Jay Balschi, III, David Welch

Publication number: 20220324891Abstract: A method for preparing isotopologues and/or stereoisotopomers of cyclic and heterocyclic alkenes and dienes is described. The method provides regio- and/or stereospecific addition of hydrogen, deuterium, tritium and a variety of other substituents to arenes, heteroarenes, and alicyclic compounds that have multiple carbon-carbon double bonds, thereby providing discrete isotopologues and stereoisotopomers of cyclic and heterocyclic alkenes and dienes with high isotopic purity and in high enantiomeric excess. Also described are isotopologues and stereoisotopomers of cyclic and heterocyclic alkenes and dienes, such as isotopologues and stereoisotopomers of cyclohexene and tetrahydropyridine, as well as products thereof, such as isotopologues and stereoisotopomers of piperidines and piperidine-containing compounds, such as methylphenidate. In addition, a method of determining the absolute configuration of stereoisotopomers of cyclohexenes is described.Type: ApplicationFiled: June 17, 2020Publication date: October 13, 2022Inventors: Walter Dean Harman, Jacob Smith, Katy Wilson, Kevin David Welch, Justin H.

Patent number: 11428105Abstract: An airfoil assembly for a gas turbine engine according to an example of the present disclosure includes, among other things, an airfoil that has an airfoil section extending from a root section. The airfoil section extends between a leading edge and a trailing edge in a chordwise direction and extends between a tip portion and the root section in a radial direction, and the airfoil section defining a pressure side and a suction side separated in a circumferential direction. A platform includes a first and second platform portions attached to the root section. Each of the first and second platform portions includes a shoe section and a platform section extending in the circumferential direction from the shoe section to establish a gas path surface, and the shoe sections of the first and second platforms are circumferentially arranged on opposed sides of the root section to capture the root section in a root cavity established between the shoe sections. A method of assembly is also disclosed.Type: GrantFiled: April 13, 2020Date of Patent: August 30, 2022Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: David A. Welch, Michael Raymond LaFavor
