  • Publication number: 20220364990
    Abstract: Methods and systems for analyzing oscillatory fluorescence representing an oscillatory ion flux associated with one or more biological cells. An illustrative method of analysis may comprise detecting fluorescence from one or more biological cells to produce a series of data points describing an oscillation pattern. A series of slopes may be calculated for the oscillation pattern. For example, a sliding window may be used to define subsets of the series of data points from which the series of slopes are calculated. Peaks of the oscillation pattern may be identified using the series of slopes. Primary peaks and secondary peaks, if any, in the oscillation pattern may be identified and characterized by multiple measurements. An aspect of the secondary peaks may be determined. Appearance of secondary peaks may indicate a potential risk of cardiotoxicity or neurotoxicity.

  • Patent number: 9869667
    Abstract: A data acquisition system coupled to a mains power source and a method of operating the data acquisition system are disclosed. A test probe is configured to be coupled to a subject, and an analog to digital converter converts a signal from the test probe to samples. A noise replica generator generates estimates of noise in the samples, and a noise removal block removes from each sample an estimate of noise therein. When the subject is undergoing stimulation, the samples are provided to only the noise removal block. When the subject is not undergoing stimulation, the samples are provided to both the noise replica generator and the noise removal block.
