    摘要: A method is provided for estimating the size of a computer network such as the Internet. A computer generates a random sample of potential network addresses and then determines whether those sample addresses are currently allocated to computers on the network. Using samples taken at multiple points in time, the computer statistically models the growth of the network. The model has unknown parameters, and values of the parameters are estimated using previously sampled data. Using the estimated parameter values in the model, the computer estimates the number of computers on the network at historical points in time. The computer also uses the model to forecast the number of computers on the network at future points in time.

    摘要: A multiuser scheme allowing for a number of users, sets of user, or carriers to share one or more channels is provided. In the invention, the available channel bandwidth is subdivided into a number of equal-bandwidth subchannels according to standard OFDM practice. A transmitter transmits data on a set of OFDM subchannels that need not be contiguous in the spectrum or belong to the same OFDM channel. A receiver receives and decodes the data and detects errors on subchannels. The receiver then broadcasts the identity of those subchannels on which the error rate exceeds a specific threshold, and the transmitter may select different subchannels for transmission based on this information.

    摘要: The subject disclosure is directed towards a hybrid stereo image/motion parallax system that uses stereo 3D vision technology for presenting different images to each eye of a viewer, in combination with motion parallax technology to adjust each image for the positions of a viewer's eyes. In this way, the viewer receives both stereo cues and parallax cues as the viewer moves while viewing a 3D scene, which tends to result in greater visual comfort/less fatigue to the viewer. Also described is the use of goggles for tracking viewer position, including training a computer vision algorithm to recognize goggles instead of only heads/eyes.

    摘要: A shared concept of time, called “graph time,” is agreed upon by all nodes within a graph. Each node maintains its own local delta representative of a difference in the node's system clock and graph time. Upon connecting to a neighbor node in a graph, a node is sent graph time as perceived by the neighbor node. In accordance with an embodiment, the node assumes that the lag time in receiving the graph time from the neighbor node is one-half of the lag time between the request for the connection and the receipt of the graph time. Graph time as sent by the neighbor node is added to one-half of the total delay and the sum is subtracted from the node's system time to calculate the delta for the node requesting connection.

    摘要: An ad-hoc discovery protocol improves reliability, security and scalability of multicast and server-based discovery. In switching from multicast to server-based discovery, the discovery client is made responsible for multicast suppression, and not discoverable devices with services. Messages include message identifier and time-to-live parameters to detect recast queries and avoid duplicating replies. A device's announcement message includes endpoint identifier, configuration number and stateless boot time parameters to detect changed device configuration and rebooted state for refreshing cached device and service descriptions. Paging parameters allow a discovery client to control the number of discovery responses returned at a time from a discovery server.
