Abstract: A sound pickup transducer array, deployed within an enclosed area, is coupled to a sound recorder. A processor, coupled to the sound recorder, provides a button or speech recognizer through which a person in the enclosed area issues a command signifying the occurrence of a sound for which categorizing is requested. The processor is programmed to respond to the issued command by extracting and storing an audio snippet copied from the audio recorder, in a digital memory, where the snippet corresponds to sound captured before, during and after the issued command. The processor communicates the stored audio snippet to an artificial intelligence system trained to categorize sounds as to what produced them. The artificial intelligence system may employ trained model feature extraction, a neural network categorization system, and/or direction of sound arrival analysis.

Abstract: The pilot communication system employs an acoustic transducer disposed on the flight deck and positioned to emit sound waves in the direction of the at least one pilot seating location. A modulator circuit is coupled to receive an audio signal from the avionics communication system and is also coupled to drive the acoustic transducer. The modulator circuit supplies to the acoustic transducer an electrical signal having an ultrasonic carrier frequency modulated by the audio signal, thereby causing the acoustic transducer to deliver a beam of ultrasonic acoustic energy, through the acoustic space, in the direction of the at least one pilot seating location, which beam of ultrasonic acoustic energy is demodulated naturally by traversal through air molecules between the transducer and the pilot seating location, thus rendering the audio signal audible by human hearing at the at least one pilot seating location.

Abstract: An aircraft includes a turbine engine, a vibration sensor, and a processor. The vibration sensor is attached to the turbine engine and is configured to output a vibration sensor signal. The processor is programmed to determine whether the vibration sensor signal indicates that fan case liner damage has occurred due to icing conditions. The processor is further programmed to indicate that a fan case inspection should be conducted in response to the vibration sensor signal indicating that fan case liner damage has occurred.

Abstract: The pilot communication system employs a transducer array of individual spaced apart speakers and/or microphones for deployment within the cockpit. A signal processing circuit interfaces with the transducer array and also with the aircraft avionics communication system, and selectively applies different time delays to the individual speakers and/or microphones to create in the array an acoustic beam having steerable coverage within the acoustic space of the cockpit. By adjusting the time delays the signal processing circuit directs and focuses sound from the speakers to the pilot and similarly focuses the microphones on the pilot's mouth. In this way the pilots can communicate with each other and with air traffic control without the need to wear headsets. The system also significantly reduces flight deck warnings from being introduced into the cabin environment.

Abstract: An aircraft includes a fuselage, a cabin surface, and a first chamber. The cabin surface is disposed within the fuselage and defines a first aperture and at least part of a cabin air mass having a first acoustic mode. The first chamber is acoustically coupled with the aperture and has a length that is one quarter of a wavelength of sound at the first acoustic mode.

Abstract: The aircraft intercom employs beam steerable microphone arrays and speaker arrays deployed in each of a plurality of zones within the aircraft. A speech recognizer generates recognition text from utterances picked up by the microphone arrays. A direction control processor analyzes the arrival time of signals from the microphone arrays to identify utterance location, which is then used to control the beam direction of at least one steerable speaker array. A dialogue manager processor coupled to the speech recognizer and to each of the plurality of microphone arrays and plurality of speaker arrays responds to a set of predefined keywords to selectively route a voiced communication from a first selected zone to a second selected zone using the microphone array and speaker array disposed in each of the first and second selected zones.

Abstract: The improved active noise cancellation system for forced air heating or cooling systems onboard aircraft employs a duct having a proximal end coupled to the fan unit to entrain the airflow stream in the direction of a distal end of the duct. A reference sensor is positioned within the proximal end of the duct. A means is provided for injecting an audio frequency control signal into the airflow stream in a manner that does not substantially impede the airflow stream. An error sensor is positioned at the distal end of the duct where it is responsive to sounds carried by the airflow stream, including the audio frequency control signal. An electronic circuit coupled to the reference sensor and to the error sensor supplies a noise abating control signal to energize the control transducer and thereby substantially reduce at least one noise harmonic of the fan unit through destructive interference.

Abstract: Sealers and methods for making a sealer are provided. In one example, the sealer includes an exterior wall extending in a longitudinal direction and at least partially surrounding a first channel. A first plurality of interior walls are spaced apart from each other and are disposed in the first channel transverse to the longitudinal direction to subdivide the first channel into a first plurality of cells.

Abstract: Audio content is controllably directed to or from an aircraft occupant, such as the pilot or a passenger using a microphone array of at least two transducers, positioned onboard an aircraft to pick up utterances of the aircraft occupant. An electronically steerable transducer array coupled to an onboard an aircraft audio system, such as an avionics communication system or in-flight entertainment system supplies audio content to the aircraft occupant. A signal processor coupled to the microphone array processes utterances sensed by the transducers using a time of arrival algorithm to determine an utterance originating direction. A controller circuit then supplies a pointing direction control signal to the steerable beamforming speaker array or microphone array based on the utterance originating direction to cause the steerable transducer array to direct the audio content in the direction of the sensed utterance and thereby direct the audio content to or from the aircraft occupant.
