  • Impedance testing with alternating current frequency control
    Patent number: 10495594
    Abstract: A controller outputs control signals controlling a frequency source to selectively apply different nonzero frequencies of alternating current at different times to an electric sensor within a microfluidic channel.
    Type: Grant
    Filed: January 30, 2015
    Date of Patent: December 3, 2019

  • Fluid testing system
    Patent number: 10473605
    Abstract: A fluid testing system comprises controlling hardware that serves to control an electric sensor on a fluid testing cassette. In one implementation, the controlling hardware is part of a cassette interface. In another implementation, the controlling hardware is part of the portable electronic device. In one implementation, the fluid testing system applies two different frequencies of alternating current are applied to two different electric sensors.
