  • Publication number: 20240171416
    Abstract: Devices, systems and methods are provided for low-power and high-sampling rate of analog signals received from sensors transported by host devices. The devices, systems and methods may be adapted to utilize GPS and PPS signals for synchronization with digitized signals generated based on the sampling of the analog signals that are simultaneously received and processed by multiple channels. Synchronized data packets may be recorded by the disclosed data acquisition systems, and may be further transmitted to host devices and remote devices.

  • Publication number: 20140072955
    Abstract: The present invention provides methods and devices for the knowledge-based discovery and optimization of differences between cell types. In particular, the present invention provides visual servoing optical microscopy, as well as analysis methods. The present invention provides means for the close monitoring of hundreds of individual, living cells over time; quantification of dynamic physiological responses in multiple channels; real-time digital image segmentation and analysis; intelligent, repetitive computer-applied cell stress and cell stimulation; and the ability to return to the same field of cells for long-term studies and observation. The present invention further provides means to optimize culture conditions for specific subpopulations of cells.
