  • Publication number: 20250167882
    Abstract: 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.

  • Publication number: 20240395114
    Abstract: 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.

  • Publication number: 20240341422
    Abstract: 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.

  • Publication number: 20240288749
    Abstract: 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.

  • Patent number: 12053064
    Abstract: 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.

  • Patent number: 12054328
    Abstract: 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.

  • Publication number: 20220324891
    Abstract: 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.
