  • Publication number: 20090119291
    Abstract: A system and method of crawling at least one website comprising at least one URL includes maintaining a lookup structure comprising all of the URLs known to be on a website; calculating a hub score for each webpage of the website to be recrawled, wherein the hub score measures how likely the to be recrawled webpage includes links to fresh content published on the website; sorting all the to be recrawled pages by their hub scores; and crawling the to be recrawled pages in order from highest hub scores to lowest hub scores. The calculating comprises computing a first value equaling a percentage of a number of new relative URLs on the to be recrawled page; computing a second value equaling a percentage of a previous hub score of the to be recrawled page; and computing the hub score as a sum of the first and the second values.

  • Patent number: 7475069
    Abstract: A system and method for prioritizing a fetch order of web pages. The method comprises extracting by a web crawler a set of candidate web pages to be crawled. Each web page in the set of candidate web pages is associated with a website in a computer network. A determination is made to determine if a first website score for the website is in a website score database. The first website score is associated with web pages in the set of candidate web pages if the first website score exists in the website score database. The set of candidate web pages is prioritized with respect to an associated website score for each web page in the candidate set of web pages. Content is retrieved from the set of candidate web. Hyperlinks are extracted from the content. The hyperlinks are stored in a memory unit.

  • Publication number: 20080276020
    Abstract: Apparatus and methods allocate I/O bandwidth of an electrical component, such as an IC, by configuring an I/O interface into various types of interfaces. In an embodiment of the present invention, an I/O interface is configured into either a bi-directional contact, unidirectional contact (including either a dedicated transmit or dedicated receive contact) or a maintenance contact used in a maintenance or calibration mode of operation. The I/O interface is periodically reconfigured to optimally allocate I/O bandwidth responsive to system parameters, such as changing data workloads in the electronic components.

  • Publication number: 20070039140
    Abstract: An apparatus for preventing removal of, or tampering with, a construction fitting includes two construction element engaging components and a fastener for connecting the two construction element engaging components to one another. The fastener includes a bolt extending between the two construction element engaging components and a nut for tightening on the bolt rigidly connecting the two engaging components with a gap therebetween. A body portion, for at least partially covering a nut, prevents access thereto by an unfastening tool with the body portion extending from the nut to a position alongside the bolt within the gap. A locking device is able to be moved relative to the body portion between a first position, in which the apparatus is removable from the construction fitting, and a second position in which the apparatus is prevented from being removed from the construction fitting with the locking device extending, in the second position, from the body portion in a direction toward the bolt with the gap.

  • Publication number: 20060022724
    Abstract: A method and circuit for achieving minimum latency data transfer between two mesochronous (same frequency, different phase) clock domains is disclosed. This circuit supports arbitrary phase relationships between two clock domains and is tolerant of temperature and voltage shifts after initialization while maintaining the same output data latency. In one embodiment, this circuit is used on a bus-system to re-time data from receive-domain, clocks to transmit-domain clocks. In such a system the phase relationships between these two clocks is set by the device bus location and thus is not precisely known. By supporting arbitrary phase resynchronization, this disclosure allows for theoretically infinite bus-length and thus no limitation on device count, as well as arbitrary placement of devices along the bus. This ultimately allows support of multiple latency-domains for very long buses.

  • Publication number: 20050237094
    Abstract: An output driver has an output multiplexor and an output current driver. The output multiplexor receives a data signal and outputs a q-node signal. The output current 5 river receives the q-node signal and drives a bus based on the q-node signal. The output multiplexor processes the data signal in various ways to generate the q-node signal. The output current driver is responsive to current control bits to select a amount of output drive current. In addition, the output multiplexor is controlled such that the output impedance of the output current driver is maintained within a predetermined range.

  • Publication number: 20050099218
    Abstract: A system including an integrated circuit memory device. The integrated circuit device comprises a register to store a value representative of an output voltage setting. A circuit holds a value representative of an adjustment to the output voltage setting. An output driver outputs a drive voltage during a calibration operation, wherein a signal is generated based on a comparison between a signal derived from the drive voltage and a reference voltage. The signal updates the value representative of the adjustment to the output voltage setting.

  • Publication number: 20050083104
    Abstract: A method of operating a memory system that includes an integrated circuit memory device is provided. A value representing an output voltage setting of an output driver of the memory device is stored in a register. The output driver outputs the drive voltage. A signal derived from the drive voltage is compared to a reference signal to generate a signal that indicates an adjustment to the output voltage setting. The output voltage setting of the output driver is adjusted using a counter that holds a count value representing an update to the output voltage setting. The count value is updated in accordance with a signal that indicates the adjustment to the output voltage setting.
