  • Method and apparatus for non-invasive assessment of ripple cancellation filter
    Patent number: 10247795
    Abstract: A method that includes deriving a first power spectral density function of a signal input to a ripple cancellation filter; deriving a second power spectral density function of a signal concurrently output from the ripple cancellation filter; frequency shaping the first power spectral density according to a spectral rejection image of the ripple cancellation filter to obtain a test power spectral density; and indicating a degraded performance of the ripple cancellation filter in the event that the test and second power spectral density functions fail to match within pre-determined criteria.
    Type: Grant
    Filed: December 30, 2014
    Date of Patent: April 2, 2019
    Assignee: GENERAL ELECTRIC COMPANY
    Inventors: Louis Martin Frigo, Melissa Jean Freeman, Margaret Ann Wiza, Douglas Link, Michael Thomas Rose, Scott Richard Weber, Andrew John Panos
  • Method and apparatus for active load impedance monitoring
    Patent number: 10132852
    Abstract: An apparatus that includes a power amplifier; a load that is operatively connected to be electrically driven from the power amplifier; and an impedance monitor that is configured to in real-time identify a favorable segment within an output waveform of the power amplifier, model the baseline power spectral density of a load driven by the power amplifier during the identified segment of the output waveform, sample an empirical power spectral density of the load during the identified segment of the output waveform, and indicate a load fault in the event that the empirical power spectral density deviates from the baseline power spectral density beyond at least one pre-determined error criteria.
