    Abstract: A throttle quadrant system for an aircraft includes: a first throttle handle to control a first engine of the aircraft, the first throttle handle having a first activatable visual indicator integrated therein; a second throttle handle to control a second engine of the aircraft, the second throttle handle comprising a second activatable visual indicator integrated therein; and at least one controller to control activation and operation of the first activatable visual indicator and the second activatable visual indicator. The at least one controller responds to first engine data related to operating status of the first engine to selectively activate the first activatable visual indicator. The at least one controller also responds to second engine data related to operating status of the second engine to selectively activate the second activatable visual indicator.

    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: To reduce engine noise in the cabin of an aircraft a plurality of error microphones is deployed at predetermined locations within the cabin to produce error microphone response signals associated with the engine noise in the cabin. Engine vibration inputs are obtained from sensors coupled to the aircraft engines. A processor is used to code the error microphone response signals into an encoded modal response in the cabin through a coding matrix. A processor is used to apply an adaptive filter to determine a plurality of modal signals needed to cancel the encoded modal response in the cabin. A processor is used to decode the modal signals into speaker input signals through a decoding matrix. Speaker input signals are then sent to a plurality of speakers to reduce the engine noise in the cabin.

    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: An aircraft includes a fuselage, a main wing coupled with and extending outward from the fuselage, and a collision avoidance system coupled with the fuselage adjacent the main wing. The collision avoidance system includes first and second laser rangefinders and a detection circuit. The first and second laser rangefinders are configured to generate laser beams laterally outward of the fuselage and include diverging lenses spreading the laser beams in a vertical dimension. The detection circuit is coupled with the first laser rangefinder and the second laser rangefinder to: detect an object within a collision risk zone adjacent to the main wing based on input from at least one of the first laser rangefinder and the second laser rangefinder; and generate an alert that the object is at risk of colliding with the main wing.

    Abstract: A flight guidance panel for an aircraft includes a subpanel display, a joystick, rotary encoders, a deflection sensor, and a processor. The subpanel display indicates autopilot modes and flight value goals and has a top-level state and a subpanel control state. The joystick is for user interaction with the subpanel display. The rotary encoder is coupled with the joystick to receive rotation inputs from a user of the joystick. The deflection sensor is coupled with the joystick to detect a deflection input from the user of the joystick. The processor is programmed to: change a state of the subpanel display to the subpanel control state corresponding to a selected subpanel in response to receiving the deflection input while the subpanel display is in the top-level state; and change the flight value goals in response to receiving the rotation inputs while the subpanel display is in the subpanel control state.
