    摘要: A system and method are described in which space-time coding techniques are used to transmit and receive multiple data streams within a near vertical incidence skywave (“NVIS”) communication system. Within the NVIS communication system, multiple independent data streams may be transmitted from a transmitting station at a high radiation angle, approaching or reaching 90 degrees. The data streams are reflected off of the ionosphere of the earth and received by one or more receiving stations. In one embodiment, the space-time coding techniques are multiple-input multiple-output (“MIMO”) signal communication techniques.

    摘要: A system and method are described for performing motion capture on a subject. For example, a computer-implemented method according to one embodiment of the invention comprise: creating a scalar field for the three-dimensional (3-D) capture volume of the subject; generating a surface mesh for the scalar field; retaining good vertices and removing bad vertices of the surface mesh; and storing the good vertices for use in subsequent reconstruction of the motion of the subject. Another computer-implemented method comprises: capturing a series of image frames of the subject over a period of time each frame each frame having a plurality of vertices defining a captured surface of the subject; establishing a reference frame having one or more of the plurality of vertices; performing frame-to-frame tracking to identify vertices within the N′th frame based on the (N−1)′th frame or an earlier frame; and performing reference-to-frame tracking to identify vertices within the N′th frame based on the reference frame to counter potential drift between the frames. Yet another computer-implemented method comprises: capturing motion capture data including a plurality of images of the N vertices during a motion capture session; retrospectively identifying X of the N vertices to track across the plurality of images where X

    摘要: An apparatus and method are described for retaining system state of an online application such as a video game. For example, a method according to one embodiment comprises: executing a application on a server in response to user input from a client; transmitting video generated by the application over a network connection from the server to the client; detecting that the network connection has become unusable or impaired; responsively pausing the execution of the application from a current point of execution; and resuming the execution of the application from the current point of execution upon detecting that the network connection has become usable or unimpaired.
