  • Publication number: 20090275265
    Abstract: A computer implemented method includes obtaining at least one current spectrum with an in-situ optical monitoring system, comparing the current spectrum to a plurality of different reference spectra, and determining based on the comparing whether a polishing endpoint has been achieved for the substrate having the outermost layer undergoing polishing. The current spectrum is a spectrum of light reflected from a substrate having an outermost layer undergoing polishing and at least one underlying layer. The plurality of reference spectra represent spectra of light reflected from substrates with outermost layers having the same thickness and underlying layers having different thicknesses.

  • Patent number: 7613756
    Abstract: An apparatus and a method are provided for generating a random number, wherein the randomness of the random number is derived from thermal noise present across a pair of resistors. Each of the pair of resistors is defined to receive a respective input voltage and add a respective noise component to the input voltage. The output from each resistor in the pair of resistors is amplified to generate a noisy analog voltage that includes a representation of the random noise components added by the pair of resistors. The randomly varying noisy analog voltage is used to control a voltage controlled oscillator (VCO). The VCO generates a random digital signal based on the randomly varying noisy analog voltage. The random digital signal generated by the VCO is used to set a number of bits for defining a random number.

  • Patent number: 7612270
    Abstract: A digital inverter formed by three carbon nanotubes (CNTs) extending vertically from a substrate, one CNT functioning as first source (S1) and having a first logic signal applied to it, another CNT functioning as second source (S2) and having a second logic signal applied to it, a third CNT functioning as gate (G), and disposed between the two sources (S1, S2). A drain (D) contact is associated with the gate (G). A logic signal applied to the gate (G) causes one or the other of the sources (S1, S2) to deflect, contacting the drain (D) and transferring its logic signal thereto—such as logic “0” on the gate resulting in logic “1” (from one of the sources) being transferred to the drain (D), and logic “1” on the gate resulting in logic “0” (from the other of the sources) being transferred to the drain (D).

  • Patent number: 7613692
    Abstract: Systems and methods that facilitate persona-based application personalization are disclosed. A persona is a conglomeration of a group of archetypal users that represent the personalization needs of many users and is based on observed behavior and patterns associated with the group of users. Users can be grouped into personas, and the personas can be analyzed to facilitate application personalization at a person level. Individual users can then be mapped to personas based on correlations of their respective individual behaviors and/or usage patters to the usage patterns of the persona as a whole.

  • Publication number: 20090266059
    Abstract: An exhaust system for use with a combustion engine is disclosed. The exhaust system may have an exhaust passageway, a reduction catalyst, a reductant injector, and a controller. The controller may have a NOX/reductant relationship map, and be configured to receive a first input relating to an amount of NOx within the exhaust passageway upstream of the reduction catalyst, and reference the NOX/reductant relationship map to determine an initial amount of reductant that should be directed into the exhaust passageway based on the first input. The controller may also be configured to receive a second input relating to performance of the reduction catalyst, determine an adjustment to the initial amount of reductant based on the second input, and regulate operation of the reductant injector to direct an adjusted amount of reductant into the exhaust passageway. The controller may further be configured to update the NOX/reductant relationship map based on the determined adjustment.
