  • Publication number: 20080201188
    Abstract: System and methods of constructing and operating a network of advertising networks in support of the real-time selection and distribution of creatives to network connected client computer systems for composited presentation on Web pages served to client computer systems. The network of networks is constructed by associating a plurality of publisher sites with a plurality of advertising networks, with each publisher site associated with one or more advertising networks, and associating a plurality of advertising campaigns with the plurality of advertising networks, with each advertising campaign associated with one or more of the advertising networks and further defined by respective campaign criteria. A campaign prioritization list is produced for each publisher site, generated based on a competitive analysis of respective campaign criteria, including a normalized campaign buy basis, employing a past-performance-based projection of a competitive completion of the advertising campaigns.

  • Publication number: 20080023825
    Abstract: A DC-DC boost converter in multi-die package is proposed having an output Schottky diode and a low-side vertical MOSFET controlled by a power regulating controller (PRC). The multi-die package includes a single die pad with the Schottky diode placed there on side by side with the vertical MOSFET. The PRC die is attached atop the single die pad via an insulating die bond. Alternatively, the single die pad is grounded. The vertical MOSFET is a top drain vertical N-channel FET, the substrate of Schottky diode die is its anode. The Schottky diode and the vertical MOSFET are stacked atop the single die pad. The PRC is attached atop the single die pad via a standard conductive die bond. The Schottky diode die can be supplied in a flip-chip configuration with cathode being its substrate. Alternatively, the Schottky diode is supplied with anode being its substrate without the flip-chip configuration.

  • Patent number: 7152039
    Abstract: A computer-implemented method of categorizing a customer includes steps of selecting a measure on which the status of the customer is to be analyzed, selecting a calculation period and selecting a comparison method. A lifecycle factor may then be computed, the lifecycle factor being related to both the size and the growth of the customer according to the selected measure. Both the size and growth are determined over two selected calculation periods using the selected comparison method. Selected customers may then be categorized into one of a plurality of lifecycle stages by evaluating a plurality of categorization criteria, at least one of the plurality of categorization criteria including the computed lifecycle factor. For example, the lifecycle stages may include the stages of New, Growing, Stable, Declining, Defected and/or Insignificant.

  • Patent number: 6777929
    Abstract: A process, computer program product, and apparatus for detecting and quantifying crosstalk instability in a read/write mechanism are provided. A write current is varied in a write circuit for exciting the write head. Measurements are taken of a magnetoresistive impedance of a read current of a read circuit. Measurements are also taken of a signal amplitude in the read circuit. A bit error rate of the overall system is also measured. The read/write mechanism is failed if the signal amplitude changes by a predetermined amount during the varying of the write current. Likewise, the read/write mechanism is failed if the error rate changes by a predetermined amount during the varying of the write current. The write-to-read signal coupling of HGA (Head Gimbal Assembly) and HSA (Head Stack Assembly), including GMR sensor, suspension and flex cable on the actuator arm, can be evaluated at component design level. The methodologies successfully simulate GMR cross talk instability inside a drive on magnetic testers.
