  • Patent number: 7924026
    Abstract: A method for determining input tones required to produce a desired output includes the step of extracting a linearization of a spectral map representing a device under test (DUT) that i) is under drive of a large signal having one or more fundamental frequencies with associated amplitudes and phases, and ii) produces an approximation of a desired output having at least one unwanted spectral component. The method includes the further step of using an inverse of the extracted linearization to determine the input tones required to produce the desired output under a given load condition.

  • Publication number: 20040167822
    Abstract: A transaction system conducts online transactions between a community of users associated with an organization and off-site vendors. Each user has an account for use in on-site transactions and other activities. The transaction system displays online items offered for sale by off-site vendors. The system can receive an order from a user for an item offered by an off-site vendor. The system determines if sufficient funds exist in the account of the user for the order and, if so, charges the account of the user for the order and transmits the order to the off-site vendor for order fulfillment. The system then pays the off-site vendor for the order.

  • Publication number: 20040033038
    Abstract: Methods for fabricating a non-linear optical (NLO) film and a NLO film structure produced thereby are provided. The methods include depositing an alignment layer material on at least one surface of a substrate, aligning the molecules of the alignment layer material in a substantially uniaxial direction, and depositing a NLO film on the alignment layer material. The methods may be advantageous in that they tend to produce NLO films having relatively strong NLO properties. The methods may be further advantageous in that they are relatively simple and may be applied to a wide range of organic NLO materials.
