  • Patent number: 11974105
    Abstract: A noise canceling audio in/out device includes an audible in/out transducer operable to convert an audible noise signal to a noise signal and convert an audio transmit (TX) signal to an audible output signal. A transducer signal of the audible in/out transducer generated by the audio TX signal is affected by the noise signal. The noise canceling audio in/out device further includes a noise canceling circuit operable to convert a digital TX signal to a TX reference signal, compare the transducer signal with the TX reference signal to produce an analog comparison signal, where the analog comparison signal includes a representation of the audio TX signal and the noise signal, and regulate the transducer signal to substantially match the TX reference signal to remove the effect of the noise signal on the transducer signal.

  • Publication number: 20240103664
    Abstract: A current reference operative drive-sense circuit (DSC) includes a current source operably coupled to a load and a voltage-mode analog to digital converter (ADC). When enabled, the current source is configured to drive a sinusoidal current reference signal to the load thereby generating a load voltage that is based on the sinusoidal current reference signal and an impedance of the load. The voltage-mode ADC is operably coupled the load and to the current source. When enabled, the voltage-mode ADC configured to perform digital sampling of the load voltage and to generate a digital signal that is representative of the load voltage. In some implementations, one or more processing modules is configured to execute operational instructions to process the digital signal that is representative of the load voltage in accordance with determining impedance of the load and/or change of impedance of the load.

  • Patent number: 11935397
    Abstract: A test system includes a test container array including a plurality of test containers and a plurality of electrodes integrated into the test container array. The test system further includes a plurality of drive-sense circuits coupled to the plurality of electrodes, where, when enabled, the plurality of drive-sense circuits detect changes in electrical characteristics of the plurality of electrodes. The test system further includes a processing module operably coupled to receive, from the drive-sense circuits, changes in the electrical characteristics of the plurality of electrodes, and interpret the changes in the electrical characteristics of the plurality of electrodes as impedance values representative of electrical characteristics of biological material present in the test container. The test system further includes a communication module operably coupled to communicate the electrical characteristics of the biological material.
