  • Publication number: 20240095661
    Abstract: A system and method for managing inventory for an electronic raffle is provided. The system may include an inventory database to store inventory data for one or more items to be sold via the electronic raffle, wherein the inventory data includes in-store inventory data and online inventory data, a mobile application configured to generate a raffle entry for the one or more items, a raffle database configured to store the inventory data and one or more raffle entries, and a middleware server configured to update the in-store inventory data stored in the raffle database based on the updated in-store inventory data obtained from the inventory database. The middleware server selects a first round winning raffle entry, transmits a notification to the mobile device associated with the first round winning raffle entry, and initiates a payment process upon determining that the first round winning raffle entry applies to the lightning round.

  • Publication number: 20240038504
    Abstract: A first edge ring for a substrate support is provided. The first edge ring includes an annular-shaped body and one or more lift pin receiving elements. The annular-shaped body is sized and shaped to surround an upper portion of the substrate support. The annular-shaped body defines an upper surface, a lower surface, a radially inner surface, and a radially outer surface. The one or more lift pin receiving elements are disposed along the lower surface of the annular-shaped body and sized and shaped to receive and provide kinematic coupling with top ends respectively of three or more lift pins.

  • Publication number: 20200402665
    Abstract: Techniques are described for predicting readmissions of patients to an inpatient healthcare facility. In an embodiment, a method comprises applying, by a system comprising a processor, applying, by a system operatively coupled to a processor, a readmission risk forecasting model to medical history data for a patient, wherein the readmission risk forecasting model comprises an attention-based graph neural network (A-GNN). The method further comprises, based on the applying, generating, by the system, a readmission risk score for the patient that reflects a probability of readmission of the patient following discharge from an inpatient healthcare facility. The method further comprises facilitating providing, by the system, the readmission risk score to at least one of the patient or a clinician involved in care of the patient.

  • Patent number: 10862163
    Abstract: Organosilicon electrolytes exhibit several important properties for use in lithium carbon monofluoride batteries, including high conductivity/low viscosity and thermal/electrochemical stability. Conjugation of an anion binding agent to the siloxane backbone of an organosilicon electrolyte creates a bi-functional electrolyte. The bi-functionality of the electrolyte is due to the ability of the conjugated polyethylene oxide moieties of the siloxane backbone to solvate lithium and thus control the ionic conductivity within the electrolyte, and the anion binding agent to bind the fluoride anion and thus facilitate lithium fluoride dissolution and preserve the porous structure of the carbon monofluoride cathode. The ability to control both the electrolyte conductivity and the electrode morphology/properties simultaneously can improve lithium electrolyte operation.

  • Patent number: 9919988
    Abstract: Processes and systems for making cyclopentadiene and/or dicyclopentadiene include converting acyclic C5 hydrocarbon(s) into CPD in a first reactor in the presence of a C1-C4 co-feedstock to obtain a product mixture, separating the product mixture in a separation sub-system such as compression train to obtain a C5-rich fraction comprising CPD and essentially depleted of hydrogen and C1-C4 hydrocarbons, dimerizing the C5-rich fraction in a dimerization reactor to obtain a product effluent comprising DCPD, followed by separating the product effluent to obtain a DCPD-rich fraction. Multiple-stage of dimerization and separation steps can be optionally used to obtain multiple DCPD-rich fractions of various degrees of purity and quantity. C5-rich fractions from various stages of the process may be recycled to the first reactor, or converted into mogas components after selective hydrogenation. C5-rich fractions and mogas components may be optionally separated to produce value-adding chemicals.

  • Publication number: 20140070626
    Abstract: The geometry of blumleins and how a switch is placed within the blumlein structure are considered. The thicker the switch, the higher the voltage it charged to without breaking down. A thicker switch can also provide a larger surface to illuminate. In one set of exemplary embodiments, the switch modules is displaced to the sides of the of the blumlein structures in a “necking” arrangement, where the switch region curves out a distance to the side. A stack of blumleins can then alternate sides, allowing for the switch region to each have a greater thickness. Another set of exemplary embodiments uses a tab structure: the top, middle and bottom conductors are all straight, but the top and middle conductors each include tabs, between which the switch is placed.
