  • Patent number: 9258203
    Abstract: A system and method for managing performance metric information is provided. Baseline performance metrics, such as network bandwidth capabilities, of various client computing devices may be obtained. The baseline performance metrics can be used to separate client computing devices into one or more groups. Based on the groupings, subsequent performance metrics associated with the one or more monitored groups can be collected in a manner to mitigate performance latencies associated with the baseline performance metric. The subsequent performance metrics can be processed to determine which metrics correspond to a potential performance problem.

  • Publication number: 20150329841
    Abstract: The present invention relates to a cellulose-degrading enzyme composition comprising one or more cellobiohydrolase and/or endoglucanase enzyme, and an effective amount of an isolated GH16 polypeptide, where the presence of the isolated GH16 polypeptide in the enzyme composition increases the rate or extent of degradation of a cellulosic substrate compared to an equivalent dosage of a corresponding cellulose-degrading enzyme composition lacking the at least one isolated GH16 polypeptide. The present invention also relates to a method for producing fermentable sugars from a cellulosic substrate using the above cellulose-degrading enzyme composition and to genetically modified microbes for produced the above cellulose-degrading enzyme composition.

  • Publication number: 20150175980
    Abstract: The present invention relates to novel polypeptides and enzymes (e.g., thermostable proteins and enzymes) having activities relating to biomass processing and/or degradation (e.g., cell wall deconstruction), as well as polynucleotides, vectors, cells, compositions and tools relating to same, or functional variants thereof. More particularly, the present invention relates to secreted enzymes that may be isolated from the fungi, Scytalidium thermophilum strain CBS 625.91, Myriococcum thermophilum strain CBS 389.93, and Aureobasidium pullulans strain ATCC 62921. Uses thereof in various industrial processes such as in biofuels, food preparation, animal feed, pulp and paper, textiles, detergents, waste treatment and others are also disclosed.

  • Patent number: 8345068
    Abstract: The present invention is directed to a method and system for continuously displaying image pages of digital content which are available over a network. More specifically, the method and system enables a user to view image pages in a continuous manner while a limited number of image pages are being downloaded at a given time. Several image pages which are adjacent to the image page(s) the user is currently viewing may be stored in temporary memory. The image pages in the temporary memory are utilized so that, within the image pages, the user can move the displayed image pages up and down without experiencing any discontinuation. In order to ensure continuous display throughout the entire digital content, the next possible set of image pages is constantly determined and obtained to update the current set of image pages in the temporary memory.

  • Patent number: 8234302
    Abstract: A system and method for controlling access to electronic content stored on a content provider's server is provided. A content provider may control and restrict unauthorized access to electronic content through an identified user account by limiting a number of devices from which requests to access the content through the account have been received. A content provider may also collect usage information of interest by monitoring authorized access to electronic content.

  • Publication number: 20120151334
    Abstract: The present invention is directed to a method and system for verifying a user for copying or printing a limited portion of digital content while allowing the user to view the digital content. The digital content may have image portions that are digital images generally scanned from a printed page of the content and text portions that are digital texts including all forms of letters, characters, symbols, etc. An interactive image document displaying image portions of the digital content is provided for secure data access to text portions. A user can request and obtain a limited text portion of the digital content or view the image portions of the digital content via user interactions within the interactive image document. While the text portions can be reproduced, copied, or printed, the image portions can not be re-used or manipulated by the user due to their non-text accessible format.
