Patent number: 9643737Abstract: Method, apparatus, and computer program product for providing a cause of a scent and/or sound detected during operation of a vehicle are provided. In the event a vehicle operator hears a sound or smells a scent while operating a vehicle, a microphone can sample the sound and/or an electronic nose can sample the scent. A sound and/or scent profile is generated from the sampled sound and/or sampled scent. The generated sound and/or scent profile are compared to known sound and/or scent profiles stored in a data structure. In the event the generated sound and/or scent profile matches a known sound and/or scent profile, the data structure is checked for correspondences between the matched, known sound and/or scent profile and a cause of the sound and/or scent. In the event a correspondence to a cause exists, then the cause is output to a user to identify the cause of the sound and/or scent.Type: GrantFiled: August 19, 2015Date of Patent: May 9, 2017Assignee: THE BOEING COMPANYInventors: Nima Barraci, Jendrick Westphal, Niels-Holger Stark, Merian Kindermann
