  • Publication number: 20260008542
    Abstract: Disclosed is a flying vehicle comprising a first rotor assembly, a second rotor assembly and a second rotor assembly pylon arranged to mount the second rotor assembly to the remainder of the flying vehicle. The first rotor assembly and the second rotor assembly are located so that they are spaced in a longitudinal direction of the flying vehicle and so they are substantially on a vertical plane that is parallel to a vertical plane aligned with a longitudinal axis of the flying vehicle. The first rotor assembly comprises a tilt-rotor arranged to tilt between delivery of substantially vertical flight thrust and substantially conventional flight thrust. The second rotor assembly comprises a stacked plurality of substantially vertical thrust rotors mounted to the pylon so as to be substantially to the same side of the pylon.

  • Publication number: 20250272373
    Abstract: In some implementations, a user device may receive, from a user of the user device, a request to initiate an application session that is associated with an application. The user device may provide, to a server device based on receiving the request, an optical code associated with the server device establishing the application session. The user device may output the optical code via an output component. The user device may receive, from the server device, a notification that an agent device has joined the application session via a scan of the optical code from the output component. The user device may enable a function of the application based on the notification indicating that the agent device is capable of facilitating a service via the application session, wherein the service is associated with the function.

  • Patent number: 12354101
    Abstract: Disclosed embodiments may include a method that includes scanning a machine-readable element, by a second user device, generated by a first user device and embedded with a tracking identifier and a product identifier and recognizing the link embedded in the machine-readable element. Responsive to recognizing the link, the method may include transmitting, by the second user device, a verification request to acquire the product to a server, wherein the verification request comprises the tracking identifier and product identifier. Responsive to receiving in-person status credentials at the second user device, the method may include rendering a description of the product on a display of the second user device, receiving a second user input confirming intent to acquire the product, and transmitting, to a server, instructions to acquire the product in response to receiving the first user input.

  • Patent number: 12299089
    Abstract: In some implementations, a user device may receive, from a user of the user device, a request to initiate an application session that is associated with an application. The user device may provide, to a server device based on receiving the request, an optical code associated with the server device establishing the application session. The user device may output the optical code via an output component. The user device may receive, from the server device, a notification that an agent device has joined the application session via a scan of the optical code from the output component. The user device may enable a function of the application based on the notification indicating that the agent device is capable of facilitating a service via the application session, wherein the service is associated with the function.

  • Patent number: 12231505
    Abstract: In some implementations, a system may receive, from a user device, a user-side request associated with establishing an application session, wherein the user-side request includes an optical code. The system may receive, from an agent device, an agent-side request associated with the agent device joining the application session, wherein the agent-side request includes authentication information that indicates that the agent device scanned the optical code from an output component of the user device. The system may send, to the user device, a notification to permit the user device to join the application session. The system may activate the application session to permit the user device and the agent device to communicate via the application session.

  • Publication number: 20220405727
    Abstract: In some implementations, a system may receive a record associated with an operation of the terminal. The system may determine that the operation is associated with a service involving a user of the terminal. The system may determine, based on the service and from location information in the record, a location of the terminal. The system may determine that an agent device is available in association with providing the service for the user, wherein the agent device is determined to be available based on a status of an application session of the agent device. The system may perform an action associated with the application session to enable the agent device to facilitate performance of the service for the user.
