Abstract: Medical tubes and methods of manufacturing medical tubes are disclosed, such as in positive airway pressure (PAP), respirator, anaesthesia, ventilator, and insufflation systems. The tube may be a composite structure made of two or more distinct components spirally wound to form an elongate tube. One of the components may be a spirally wound elongate hollow body, and the other component an elongate structural component spirally wound between turns of the spirally wound hollow body. Alternatively, the tube need not be made from distinct components. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or have other medical uses.

Abstract: A system and method are described for managing the state of an online video game. A method includes initiating a new online video game in response to user input from a client device, the online video game being in a first state on a first server when initiated; executing the online video game on the server, thereby causing the online video game to enter a second state; pausing or terminating the online video game; determining differences between the first state and the second state and generating difference data containing the differences; transmitting the difference data over a network to a second server; and recreating the second state from the difference data and the first state in response to user input indicating that the user wishes to resume the online video game and in response to the second server being selected as the server on which to execute the video game.

Abstract: An electronic game server receives a request from a client device to establish a real-time interactive gaming session, determines a device capability of an output device associated with the client device, determines a connection capability of the network connection, determines one or more target quality parameters for the real-time interactive gaming session based on the device capability and the connection capability, selects a first virtual machine of the plurality of virtual machines based on the one or more target quality parameters, establishes the real-time interactive gaming session with the client device, and provides to the real-time interactive gaming session, in accordance with the resource profile of the first virtual machine, resources for processing inputs from the client device and generating gameplay outputs in accordance with the processed inputs within the real-time interactive gaming session.

Abstract: A system includes a video source device connected to a video destination device via a network. The video source device includes a network interface and an encoder coupled to the network interface. The encoder is configured to encode a first stream of rendered video frames having a first frame rate to generate a second stream of encoded video frames for transmission over the network via the network interface, wherein the second stream has a second frame rate greater than the first frame rate. As part of this encoding process, the encoder is configured to selectively encode multiple instances of at least one video frame of the first stream for inclusion in the second stream to compensate for the difference between the first frame rate and the second frame rate.
