Abstract: Methods, apparatus, systems, and computer-readable media are provided for providing context specific schema files that allow an automated assistant to broker human-to-computer dialogs between a user and an application that is separate from the automated assistant. The context specific schema file can provide the automated assistant with sufficient data to be responsive to user queries without necessarily communicating with a remote device, such as a server. Multiple different context specific schema files can be made available to the automated assistant according to a context in which a user is interacting with the automated assistant. In this way, latency otherwise exhibited by the automated assistant can be mitigated by providing the automated assistant with the information needed to respond to a user without continually retrieving the information over a network.

Abstract: Techniques for resource-based network traffic management are described. A service of a cloud provider network receives a traffic policy, the traffic policy identifying a path to a gateway to an external network, the path identifies at least one network function in the path by a resource identifier of the cloud provider network. Traffic policy association data is received, the traffic policy association data associating the traffic policy with one or more virtual networks hosted by the cloud provider network. A network configuration of the cloud provider network is updated to route network traffic from a first virtual network to the gateway to the external network through the network function.

Abstract: A system for sharing visual data from a medical device includes: a first user terminal configured to obtain medical device visual data, a sharing device connected to the first user terminal, configured to receive the medical device visual data from the first user terminal and communicate it to a server, and a remote user device. The sharing device is operable to receive a command to share the medical device visual data, and in response to receiving that command, to communicate the medical device visual data to the server. The remote user device is operable to receive a communication from the server including the medical device visual data, and to display the medical device visual data via its respective display.

Abstract: We provide an imaging system for use in a fluoroscopy procedure carried out on a subject, the imaging system being configured to receive images of a portion of the subject from an image acquisition device, the imaging system comprising an interface module for displaying images received from the image acquisition device to a user, and an optimisation module for determining, based on an image received from the image acquisition device, one or more properties of the image, wherein the optimisation module is configured to output a control routine.

Abstract: The present disclosure relates generally to the assessment and treatment of vessels, including for percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). For example, some embodiments of the present disclosure are suited for identifying the available intervention technique(s) suitable to achieve a desired outcome selected or input by a user. For example, in some implementations a method comprises receiving pressure measurements obtained by one or more intravascular pressure-sensing instruments positioned within a vessel of a patient; receiving an input from a user regarding a desired pressure value for the vessel of the patient; identifying an available treatment option based on the received pressure measurements and the desired pressure value; and outputting, to a display device, a screen display including a visual representation of the available treatment option. Related devices and systems are also described.

Abstract: Systems and methods are provided to enable packets of network traffic to be routed to a network appliance. Bidirectional flows of network traffic can be routed to the same network appliance based on flow information of the corresponding packets. A network device may intercept the packet corresponding to a first flow and route the packet to a specific network appliance based on the first flow information. The network device may generate a direction agnostic tuple value based on data groups of the first flow information. The network device may propagate the direction agnostic tuple value across availability zones to a second network device in a different availability zone to store the direction agnostic tuple value for use for subsequent packets. The second network device can receive a second packet and transmit the second packet to the same network appliance based on the direction agnostic tuple value.
