Abstract: Embodiments are directed to measuring, on a periodic basis by a hearing device, one or more transfer functions, each of the one or more transfer functions comprising a receiver-to-microphone acoustic transfer function of the hearing device. A plurality of health indicators of the hearing device are calculated over time using a measured characteristic of each of the measured transfer functions and a nominal characteristic of each of the measured transfer functions. Using the plurality of health indicators, degradation or failure of any of the receivers, any of the microphones, or a component in an acoustic path between one or more receivers and one or more microphones is detected. One or both of recommended actions and warnings are generated in response to detecting degradation or failure of any of the receivers, any of the microphones, or the component.

Abstract: A mixer assembly for mixing, in a mixing tube of an exhaust aftertreatment system, a reductant with an exhaust gas from an internal combustion engine may include a mixer and an electrically heated heating element. The mixer may be positioned in proximity to the reductant injector. The electrically heated heating element may be positioned in proximity to an impingement surface of the mixer. The reductant may directly impinge, after being injected, on the impingement surface causing the reductant to vaporize and mix with the exhaust gas forming a vaporized reductant and exhaust gas mixtures that flows along a flow path defined by the mixing tube. The vaporized reductant and exhaust gas mixture may be heated and further mixed by the electrically heated heating element.
