  • Patent number: 11974966
    Abstract: A medical product includes a bladder, a filtration device, and a sterile product concentrate. The bladder has a perimeter seal and defining a sterile chamber. The filtration device includes a stem and a filter membrane disposed in line with the stem. The stem extends through the perimeter seal and has an inlet end accessible from outside of the perimeter seal and an outlet end in fluid communication with the sterile chamber. The filter membrane can have a nominal pore size in a range of approximately 0.1 ?m to approximately 0.5 ?m, wherein the filter membrane is shaped as a hollow fiber with a wall and pores residing in the wall of the fiber. The sterile product concentrate is disposed in the sterile chamber and adapted to be reconstituted by the introduction of a pharmaceutical fluid into the chamber through the filtration device.

  • Publication number: 20240104560
    Abstract: Systems and techniques for digitization of payment cards for Web 3.0 (“Web3”) and metaverse transactions are provided. The described systems and techniques allow for the use of non-fungible tokens (NFTs) to represent a payment token for making a payment inside a Web3 and Metaverse environment. Indeed, the described systems and techniques provide a financial NFT enabled representation of a payment card account as a token in a blockchain network, which can then be used to facilitate Web3 payments with real-time fiat to crypto exchanges.

  • Publication number: 20230368197
    Abstract: A method for mediating an atomic swap includes: receiving a swap request from a first computing device including a first address associated with a first blockchain and a network identifier associated with a second blockchain; identifying a second computing device using the network identifier and a second address associated with the second blockchain; generating a proof value and a hashlock using the proof value; transmitting (i) the hashlock and second address to the first computing device, and (ii) the hashlock and first address to the second computing device; verifying a first blockchain transaction on the first blockchain for transfer to the first address, and a second blockchain transaction on the second blockchain for transfer to the second address; and transmitting the proof value to blockchains node associated with the first and second blockchains.

  • Publication number: 20230092733
    Abstract: An access control method comprises: providing access profiles for users, wherein each access profile comprises an access profile identifier and at least one personal identifier mapped to one or more obfuscated payment numbers, and wherein each of the at least one personal identifiers is a non-payment identifier issued by an identity provider; receiving, from a terminal of a service provider, a request to validate permission for a user of a payment device to access a resource made available by the service provider, the request comprising an obfuscated payment number read by the terminal from the payment device; determining whether there is a match of the obfuscated payment number read by the terminal and one of the obfuscated payment numbers of the access profiles; and transmitting at least one of the identifiers of the matched access profile to the service provider for matching to a stored identifier associated with the resource.
