Abstract: A method for providing a user agent (UA) with service identification data. The method includes an application server (AS) transmitting Session Initiation Protocol (SIP) data. The SIP data comprises an identifier of the AS and a service identifier for at least one service supported by the AS. The method further includes the UA receiving the SIP data.

Abstract: Systems and methods are provided for cross-border network messaging. An example computer-implemented method includes receiving, from a sending institution, a transfer request for a real time transfer from a sender to a recipient, where the transfer request includes an amount to be transferred and an identifier unique to the recipient. The sending institution is in a first zone having a first domestic currency and the recipient is in a second zone having a second domestic currency, and the amount is in the second domestic currency. The method also includes confirming that a liquidity of the sending institution in the first currency is sufficient and, in response to the confirmation, transforming the transfer request based on a rule specific to the second zone. The method includes transmitting the transformed transfer request to a core computing device in the second zone.

Abstract: A method for performing initial registration is provided. The method includes receiving a server timeout message, the server timeout message including at least a field set to a value equal to a value received during a first registration. The method further includes initiating restoration procedures by performing an initial registration.

Abstract: A display system may include a light source that emits input light having a wavelength within a source wavelength range and an array of color conversion units overlapping a display area. A first set of color conversion units of the array of color conversion units may include a first color conversion medium that converts the input light to a first color of light having a wavelength within a first wavelength range that is different than the source wavelength range. The display system may also include a waveguide having an out-coupler that directs the input light from the light source toward the array of color conversion units. Various other devices, systems, and methods are also disclosed.

Abstract: According to one implementation of the present disclosure, a method for bill presentment is disclosed. At a computing device associated with a consumer, the computing device having one or more processors, memory, and a display, the method includes: receiving, at a network integrator interface on a digital messaging system, authentication or transaction data from the consumer on the computing device; matching, by the network integrator interface, authentication or transaction data of the consumer with billing data of one or more biller systems associated with the consumer; and providing, by the network integrator interface, the billing data to the consumer.

Abstract: The disclosure relates to a deferred real-time payment (RTP) in a trusted and secure system environment to pay for a deferred fulfillment order. The deferred fulfillment order includes products or services that may be fulfilled in part or in full after authorization of the deferred RTP. To facilitate trust and security, a deferred payment system may digitally sign certificates issued to various entities in the system environment. Devices in the system environment may transmit and receive messages to create and later settle deferred RTPs that are trusted based on authentication of the digitally signed certificates, which mitigate against security threats such as man-in-the-middle attacks in a communication network.

Abstract: A payment card system including: an artificial intelligence (AI) platform configured to: identify a first payment card account of a cardholder; receive, via a message or messenger-based channel, an inquiry related to a purchase the cardholder desires to make using the first payment card account; interactively communicate with the cardholder via the message or messenger-based channel using artificial intelligence; determine a cost of the purchase relative to the balance of the first payment card account; if the cost of the purchase exceeds the balance of the first payment card account, identify a second payment card account of the cardholder; and initiate creation of a third payment card account that combines at least a portion of the balance of the first payment card account and at least a portion of a balance of the second payment account. The payment card system also includes one or more entities of a bank-related network.

Abstract: A payment card system comprising an artificial intelligence (AI) platform configured to: acquire, via a first communication channel, payment card information associated with a user; identify a payment card account of the user based on the payment card information; receive from the user, via the first communication channel, a command related to a function to be performed with respect to the payment card account; and transmit the command, via a second communication channel, to a remote device in a bank-related network; and the remote device of the bank-related network. The payment card system also comprises a remote device. The remote device comprises: a memory; a receiver configured to receive the command transmitted from the AI platform; and a processor coupled to the memory, the processor configured to: authenticate the user in the bank-related network, wherein the first communication channel is different from the second communication channel.

Abstract: A prepaid spending card for the storage of funds, the prepaid spending card comprising a single primary account number. The prepaid spending card further comprises a first purse identified by a first pseudo DDA, the first purse authorized to received funds from any available funding source, and a second purse identified by a second pseudo DDA, the second purse authorized to send and receive funds only from restricted sources. The first pseudo DDA is used to route incoming funds to the first purse and the second pseudo DDA is used to route incoming funds to the second purse. Moreover, the first purse receives funds from any available funding source and the second purse receives from restricted funding sources.

Abstract: A low-loss waveguide that can be curved aggressively, that is, curved with a radius of curvature that is substantially zero, in the plane of propagation, without radiating, is formed by a slab of dielectric material having four metal plates, two on each opposite surface of the slab and mutually spaced to define in the dielectric slab between the four metal plates a confinement zone. In use, electromagnetic radiation injected in one end of the zone by suitable input means will propagate throughout the zone to an extraction means. Lower loss and better confinement of the radiation may be obtained by providing plugs of dielectric material adjacent the inwardly-facing edge of each of the metal plates. Embodiments of the invention can be used to implement integrated optical devices and circuits for routing or processing light signals.
