  • Publication number: 20150165322
    Abstract: A video server is configured to provide streaming video to players of computer games over a computing network. The video server can provided video of different games to different players simultaneously. This is accomplished by rendering several video streams in parallel using a single GPU (Graphics Processing Unit). The output of the GPU is provided to graphics processing pipelines that are each associated with a specific client/player and are dynamically allocated as needed. A client qualifier may be used to assure that only clients capable of presenting the streaming video to a player at a minimum level of quality receive the video stream. Video frames provided by the video server optionally include overlays added to the output of the GPU. These overlays can include voice data received from another game player.

  • Patent number: 9031451
    Abstract: An example toner cartridge includes a reservoir for containing toner and an exit port in fluid communication with the reservoir. A shutter is positioned at the exit port and movable between an open position and a closed position. A first linkage member is operatively connected to the shutter to open the shutter upon being actuated by a first engagement feature. A second linkage member is pivotally attached to a side wall of the housing and biased toward a home position. A third linkage member is movable with the second linkage member. When the second linkage member is in the home position, the third linkage member is in a blocking position preventing the first linkage member from opening the shutter. When the second linkage member pivots away from the home position, the third linkage member moves to a non-blocking position permitting the first linkage member to open the shutter.
