  • Current-based status monitor for electronic controller of multiple fluid line heaters
    Patent number: 10254010
    Abstract: An electronic module housing having a rounded stylized dog-bone-type shape and an equatorial partial light bar. The shape provides a view of parts of the light bar from many locations. The controller circuitry can detect a malfunction among one or more of a plurality of current-drawing components by detecting that the total cumulative current drawing by all the components falls outside a predetermined nominal range.
    Type: Grant
