Abstract: Systems and methods are described for streaming data between a user device and a remote computing environment via a “switchboard” service that enables interaction without the user device or the remote computing environment establishing additional connections. A first routing device receives a connection from a user device that requests routing a data stream to or from a remote computing environment. The first routing device processes the request by generating a token, which is passed to the remote computing environment along with the request. The remote computing environment passes the token to a second routing device, which decodes the routing token to identify the first routing device. The second routing device then passes the request token to the first routing device, which responds by establishing a route for streaming data between the connection made with the user device and the remote computing environment via the routing devices.

Abstract: Systems and methods are described for communications between computing devices via an ephemeral data stream routing service, which allows the devices to establish a single-use connection for streaming arbitrary amounts of data. A computing device may request an ephemeral data stream from the ephemeral data stream routing service, which may respond by creating an endpoint and providing a single-use URL that locates the endpoint. The sending and receiving computing devices may then use the single-use URL to connect to the endpoint, which may be implemented on a single routing device or a pair of routing devices within the ephemeral data stream routing service. The service then relays a data stream from the sender to the receiver, and may forward the data stream from one routing device to another within the service as needed. The ephemeral data stream routing service then removes the endpoint and invalidates the single-use URL.

Abstract: A system for the detection of blood vessels includes an image sensor coupled to generate video data including a sequence of images of the blood vessels, and a heart rate monitor to measure a heart rate of a patient and to generate heart rate data. A controller is coupled to the image sensor to receive the video data, and coupled to the heart rate monitor to receive the heart rate data. The controller includes logic that when executed by the controller causes the controller to perform operations including isolate localized motion of the blood vessels in the video data using the heart rate data. The controller also computes a blood vessel mask (that includes differences between the video data and the localized motion of the blood vessels) and combined video data (that includes the video data and the blood vessel mask).
