  • Patent number: 11934290
    Abstract: Certain aspects involve providing automated performance monitoring of statistical models. For example, a processing device is used for performing a statistical analysis on information in an archive to extract historical data, scores, and attributes. The processing device calculates performance metrics based at least in part on the historical data, scores, and attributes. The processing device pre-calculates summary performance data based at least in part on the performance metrics. The summary performance data is stored in files with predefined layouts, which are stored in a non-transitory, computer-readable medium. Segmented data is presented from a file to a user through a graphical user interface (GUI). In some aspects, various reports of the segmented data are presented interactively by detecting a selection by the user of a segmentation and displaying the corresponding segmented data.

  • Publication number: 20060006947
    Abstract: An electronic circuit includes a current mirror bias circuit and a power amplifier that has a power transistor for amplifying radio frequency signals such that the output collector current of the power transistor is approximately constant over a wide range of varying power supply voltages. The power transistor is biased by a current mirror biasing circuit that has a reference voltage that maintains the quiescent DC collector current at an approximately constant value. The reference voltage may be varied to provide control of the output power of the power amplifier.

  • Patent number: 5851602
    Abstract: A plasma enhanced chemical vapor deposition process for depositing conformal silicon oxide thin films useful to make thin film transistors which have stable electrical properties and low charge centers onto a substrate comprising flowing a precursor gas mixture of silane and nitrous oxide, the latter at a high rate, at a pressure of at least about 0.8 torr and a temperature of from about 250.degree. to 350.degree. C. The effective volume of the reaction region between the gas manifold inlet and the substrate during processing is kept small.
