  • Patent number: 10473548
    Abstract: A device for detecting presence of a fluid is described, and includes a resistive sensing element including a first conductive element proximal to a second conductive element, wherein the first conductive element is electrically isolated from the second conductive element, and a controller disposed to monitor electrical conductivity between the first conductive element and the second conductive element. The controller includes an instruction set that is executable to periodically monitor a signal associated with the electrical conductivity between the first conductive element and the second conductive element. A baseline value for the electrical conductivity between the first conductive element and the second conductive element can be determined based upon the periodically monitored signal, and a signal waveform can be determined based upon the periodically monitored signal. The signal waveform can be characterized, and presence of a fluid can be detected based upon the characterized waveform.
