  • Publication number: 20110033032
    Abstract: A method and corresponding apparatus are provided to detect false answer supervision by determining false answer supervision as either as a function of a number of completed calls of short duration or as a function of a distribution of differences between timestamps of alert signals and timestamps of connect signals used to complete calls, detecting false answer supervision based on the indicator of false answer supervision determined by either functions separately or in combination, and affecting a decision in response to the detecting.

  • Publication number: 20100220591
    Abstract: A decision about provider quality based on a quality metric observed says little about the quality of the provider. Further, the decision may be biased by a variation in customer contributions to the quality metric observed or by a variation in a number of completed calls received by a provider. Accordingly, a method and corresponding apparatus are provided to evaluate quality and to correct bias by determining a standard that accounts for at least one source of bias, comparing an observed measure of a provider against the standard to produce an evaluation of the observed measure of the provider, and affecting a decision about the quality of the provider based on the evaluation. As a result, an unbiased decision, for example, to scrub a provider can be made and in some instances, a provider may be rescued from being scrubbed.

  • Patent number: 7623594
    Abstract: An SDARS receiver for use with at least two antennae, each of which receives bitstreams from a first satellite, bitstreams from a second satellite, and bitstreams from a terrestrial repeater, including demodulators configured to switch between demodulating bitstreams from the satellites and to switch between demodulating bitstreams from the terrestrial repeater, and a processor coupled to the demodulators, the processor being configured to switch the demodulators according to a variety of algorithms.

  • Publication number: 20090222931
    Abstract: A newly identified oncogene with kinase-domain (NOK) and its encoded polypeptide, and vectors, fusions, host cells and transgenic animals comprising the said nucleotide sequence. Furthermore, the present invention also describes the methods for diagnosing diseases including tumor and the methods for screening agents capable of inhibiting the occurrence and/or metastasis of tumor.

  • Patent number: 6156465
    Abstract: A method of crosstalk correction comprises producing a calibration image having different printed image densities in grayscale, measuring the printed image densities at the different light exposure values to obtain a correlation of printed density in grayscale as a function of light exposure value over a range of light exposure values, obtaining experimental analytical density values for a selected light exposure value within the range of light exposure values and using the correlation of printed density as a function of light exposure value and the experimental analytical density values to correct for crosstalk.
