  • Gas bubble sensor
    Patent number: 11850344
    Abstract: Systems, devices, and methods are provided for sensing gas bubbles within a liquid flow line, such as within a medical device. The systems, devices, and methods can measure a change in capacitance across a pair of conductive plates to calculate a volume of gas in a flow line. If a calculated volume of gas exceeds an established threshold, an alert can be sent and/or changes made to operation of the device.
    Type: Grant

  • SYSTEMS AND METHODS FOR DEVICE-INDEPENDENT COLOR MEASUREMENTS FOR COLORIMETRIC SENSING
    Publication number: 20230175972
    Abstract: A calibration method and related systems for colorimetric chemical assay and a fluid sensor apparatus using the same are provided. Reference measurements are taken from both a digital camera and a spectrometer. The digital camera is installed in the fluid sensor apparatus. Subsequently, color measurements from the digital camera are then converted and compared to prior spectrometric measurements to perform a colorimetric analysis.
