Publication number: 20250167882Abstract: Consistent the present disclosure, a network or system is provided in which a hub or primary node may communication with a plurality of leaf or secondary nodes. The hub node may operate or have a capacity that may be greater than that of the leaf nodes. Accordingly, relatively inexpensive leaf nodes may be deployed that receive data carrying optical signals from and supply data carrying optical signals to the hub node. One or more connections may couple each leaf node to the hub node, whereby each connection may include one or more spans or segments of optical fibers, optical amplifiers, and optical add/drop multiplexer, for example. Consistent with an aspect of the present disclosure, optical subcarriers may be transmitted over such connections. The subcarriers may be generated by a combination of a laser and a modulator, such that multiple lasers and modulators are not required, and costs may be reduced.Type: ApplicationFiled: May 21, 2024Publication date: May 22, 2025Inventors: Amir Jafari, Kuang-Tsan Wu, David Welch, Steven Joseph Hand, Mohamed Osman

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: 20240288749Abstract: 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: 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
