  • Patent number: 11954965
    Abstract: Technology for managing a player session at a gaming table is disclosed. A table management system receives identifying information of a player seated at the gaming table transmitted by a mobile device associated with the player. The identifying information includes a seating position of the player at the gaming table, the seating position determined by the mobile device through interaction with a locating device placed at the seating position at the gaming table. The table management system generates the player session for the player for playing a wagering game at the gaming table using the identifying information of the player transmitted by the mobile device.

  • Publication number: 20240099564
    Abstract: An imaging system for use in a patient is provided. The system includes an imaging probe, a rotation assembly, and a retraction assembly. The imaging probe collects image data from a patient site and includes an elongate shaft with a proximal end and a distal portion, with a lumen extending therebetween. A rotatable optical core is positioned within the elongate shaft lumen and an optical assembly is positioned in the elongate shaft distal portion. The optical assembly directs light to tissue at the patient site and collects reflected light from the tissue. The rotation assembly connects to the imaging probe and rotates the optical assembly. The retraction assembly connects to the imaging probe and retracts the optical assembly and the elongate shaft in unison.

  • Publication number: 20240086919
    Abstract: Various embodiments of the present disclosure provide techniques for facilitating a credential-less exchange over a network using a plurality of identifier mappings, member interfaces, and security code tuples that are tailored to an ephemeral key. The techniques may include receiving a secured interaction request and issuing or enabling a previously issued universally unique ephemeral key (UUEK) in response to the secured interaction request. The techniques may include validating a user, instrument, or UUEK and, in response, storing a secured event for the user, instrument, or UUEK and providing a secured interaction response indicative of the secured event. The techniques may include subsequently receiving an exchange request for executing a value-based exchange using the UUEK and facilitating the exchange request based at least in part on the secured event.

  • Patent number: 11859208
    Abstract: This disclosure relates to compositions and methods of reversing senescence in T cells by interrupting vasoactive intestinal peptide (VIP) signaling and/or inhibiting phosphatidylinositol-3-kinase (PI3 kinase) inhibitor signaling and uses in managing cancer and chronic viral infections. In certain embodiments, the disclosure contemplates methods of reversing T cell senescence by mixing T cell in vitro with an agent that prevents VIP from interacting with VIP receptors and/or a PI3 Kinase inhibitor. In certain embodiments, the disclosure contemplates the expansion of senescent T cells by mixing with a PI3 kinase inhibitor, an agent that block VIP and VIP receptor signaling, a VIP degrading enzyme, and combinations thereof.
