Abstract: Apparatus for translating audio signals and producing a visual color display that portrays music. Circuits responsive to audio signal amplitude cause the display brightness to vary in accordance with the loudness of the music source. Circuits responsive to audio signal frequency content cause the color of the display to vary in accordance with the frequency spectrum of the music source. The audio frequency spectrum is evaluated by circuits which divide the spectrum into multiple contiguous frequency bands without the use of traditional filtering techniques. A palette of preselected light colors is assigned to the frequency bands such that each band is displayed as a unique color. The display apparatus is comprised of multiple colored light sources enclosed within a curved translucent light diffusion globe. Light sources are activated singly or in combinations of two adjacent light sources to produce the most attractive color blending to appear on the surface of the globe.

Abstract: Disclosed is a combined flight data recorder data aquisition circuitry (10) and airborne integrated data circuitry (12) that can be variously packaged to supplement and update existing aircraft systems or serve as a standalone flight data recording and/or airborne integrated data system. The flight data recorder system circuitry (10) and airborne integrated data system circuitry (12) are separately programmed microprocessor based systems that are capable of processing aircraft parametric signals provided by a variety of aircraft signal sources. In the disclosed arrangement, the airborne integrated data system circuitry (12) is arranged and programmed to automatically monitor engine start and shutdown procedures, aircraft takeoff and cruise and to provide a landing report that indicates fuel consumption and landing weight.
