Abstract: A method for notifying a subset of users of a messaging channel may include publishing one or more shadow channels for the messaging channel. Each shadow channel is configured to prevent transmission of an event notification to one or more unregistered user devices. The method may also include broadcasting one or more event notifications to one or more registered user devices when an event associated with the one or more shadow channels is triggered. The one or more registered user devices are subscribers to the one or more shadow channels.

Abstract: During a video conference meeting, a virtual assistant may provide in-meeting assistance responsive to verbalized group intent. The virtual assistant may automatically perform actions, such as recording notes, creating calendar events, and obtaining information derived from previous meetings, in response to the detected group intent. The virtual assistant may also provide pre-meeting assistance.

Abstract: Embodiments are described for provision of a brute force attack protection service to a middleware service, for example in the context of a distributed computing system receiving requests for connection from remote client devices. The brute force attack protection service may avoid relying upon presenting a Turing challenge at client devices for identifying and handling malicious requests for access or resources at the middleware service.

Abstract: An audio/video stream may include an audio stream and a video stream. The video stream may be decomposed into a plurality of face streams. Each of the face streams may include a cropped version of the video stream and be focused on the face of one of the individuals captured in the video stream. Facial recognition may be used to associate each of the face streams with an identity of the individual captured in the respective face stream. Additionally, voice recognition may be used to recognize the identity of the active speaker in the audio stream. The face stream associated with an identity matching the active speaker's identity may be labeled as the face stream of the active speaker. In a “Room SplitView” mode, the face stream of the active speaker is rendered in a more prominent manner than the other face streams.

Abstract: According to a first aspect, there is provided a cross-border payment server comprising: at least one processor; at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the cross-border payment server at least to: that receive, from an account, an indication of a fund amount to finance cross-border transactions; calculate assets purchased by the fund amount; supply the account with the purchased assets; update the assets held in the account resulting from assets traded during each cross-border transaction involving the account; and effect a return of funds in response to sale of the assets held in the account.

Abstract: Embodiments are described for provision of video conferencing with, for example, a virtual whiteboard for displaying annotations and streaming of a physical whiteboard, indexing of physical whiteboard content, and compositing and projection of remote whiteboard content onto a local whiteboard.

Abstract: Embodiments are described for customizing a video conferencing user experience using a virtual assistant, and/or assisting a user in diagnosing issues concerning a video conferencing user experience. The virtual assistant may address issues based on automatically detected meeting quality measures as well as issues verbally communicated to the assistant by a user at an endpoint.

Abstract: System and method for facilitating purchase of products from a plurality of different merchants. The system includes a payment processor module that is in communication with a first e-commerce platform associated with a first merchant and a second e-commerce platform associated with a second merchant. The payment processor module is configured to receive data comprising: first product information relating to a first product to be purchased by a customer through the first e-commerce platform; and second product information relating to a second product to be purchased by the customer through the second e-commerce platform. The data is received in real-time without delay after the customer provides an indication of intent to purchase the first and the second products. The payment processor module is further configured to initiate a single transaction based on the data that is received, wherein the single transaction corresponds to the purchase of the first and the second products by the customer.

Abstract: A totem pole power factor correction (PFC) converter is disclosed. The totem pole PFC converter includes a first transistor having a first current terminal coupled to a first node, a first control terminal, and a second current terminal. Also included is a second transistor having a third current terminal coupled to the second current terminal at a second node, a second control terminal, and a fourth current terminal coupled to a third node. A first rectifier is coupled to the first node and a first current sense resistor is coupled between the first rectifier and a fourth node. A second rectifier is coupled to the third node and a second current sense resistor coupled between the second rectifier and the fourth node. A current sense voltage for an analog controller is generated by current alternately flowing through the first current sense resistor and the second current sense resistor.

Abstract: A method for immutability of review verifications includes: storing a blockchain comprised of blocks; receiving a review submission including a reviewer identifier, entity identifier, and review data comprising feedback; identifying a review identifier unique to the review submission; generating a new review block comprising a block header and data values, the data values including the review submission including the review identifier; receiving verification submissions including a different reviewer identifier, the review identifier, and verification data indicating positive or negative verification of the review submission; and generating verification blocks, each comprising a block header and data values, wherein each of the verification submissions are included in the one or more data values.
