  • Patent number: 9106464
    Abstract: Distortions of both amplitude and phase along a transmission line are compensated for by a trace canceller inserted between a transmitter and a receiver. The trace canceller has an equalizer that compensates for a trace length between the transmitter and the trace canceller. A variable gain amplifier between the equalizer and an output buffer has its gain controlled by an automatic gain control circuit that compares low-frequency swings of the input and output of the trace canceller. The gain of the variable gain amplifier is reduced to prevent the output buffer from saturating and clipping peak voltages on its output. Thus both the variable gain amplifier and the output buffer remain in the linear region. Training pulses from the transmitter are passed through the trace canceller without clipping of peak voltages, allowing the transmitter and receiver to adjust transmission parameters to best match the transmission line.

  • Patent number: 9094245
    Abstract: A redriver chip is inserted between a transmitter chip and a receiver chip and re-drives differential signals from the transmitter chip to the receiver chip. The redriver chip has switched output termination that switches to a high value to detect far-end termination at the receiver chip, and to a low value for signaling. An output detector detects when the receiver chip has termination to ground and enables switched input termination to provide termination to ground on the lines back to the transmitter chip so that the far-end termination on the receiver chip is mirrored back to the transmitter chip, hiding the redriver chip. An input signal detector detects when the transmitter chip begins signaling and enables an equalizer, limiter, pre-driver, and output stage to re-drive the signals to the receiver chip. The input signal detector also causes the switched output termination to switch to the low value termination for signaling.

  • Publication number: 20150067185
    Abstract: According to the disclosure hereof, the functionality of a server can be extended to collect data on content streams that the server is delivering to clients, and to beacon certain data back an analytics system to facilitate monitoring of, reporting on, and analysis of the delivery of content streams. At various stages of the streaming process, a server can read and update state information (for example cookie data) on the requesting client reflecting, for example, status in playing a particular stream. Based on the client's requests and the state information at each stage, the server can beacon appropriate information about the stream and its playback status back to the analytics system. The teachings hereof are particularly useful, without limitation, in streaming media analytics and for segment-based streaming approaches, including over HTTP.

  • Publication number: 20150002167
    Abstract: An in-situ unplug detector circuit detects when a cable is disconnected or unplugged. Detection does not have to wait for normal signaling to pause, such at the end of a frame or timeout. Instead, detection occurs during normal signaling. When the cable is disconnected, the transmitter no longer drives the load at the far end of the cable, and thus can drive the near end to a higher high voltage and to a lower low voltage. The increased voltage swing is detected by a detector at the near end that amplifies the transmitter output to the cable. A fast detector has a higher bandwidth and faster response time than a slow detector, and generates a fast detect signal that crosses over a slow detect signal. When the cable is disconnected, the fast detect signal again crosses over the slow detect signal, and decision logic activates an unplug signal.

  • Publication number: 20140215455
    Abstract: A system for package pre-fetching for a remote program installation includes a service node having a processor, a computing node type database, and a cache, the service node being configured to receive at least one package request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node, and determine a package request sequence by which the computing node issues the at least one package request according to a type of the computing node. In another embodiment, a method includes receiving a package request from a computing node, and determining a package request sequence by which the computing node issues at least one package request according to a type of the computing node, so as to pre-read a subsequent package into a cache before the computing node issues a request for the subsequent package.

  • Patent number: 8670161
    Abstract: A printer driver enables a user to determine whether the features that are required to print a specified job are available to a selected network printer. The printer driver queries the selected printer to acquire the current status and other relevant information for each feature that is required to print the job, then provides the results of the query at a user interface. Accordingly, if any of the required features are unavailable to the selected printer, the user can print the job using another printer or take some other appropriate action.
