Appl. No.:

12/266159

Inventors:

Gary L. Fox - Oro Valley AZ, US
Nicholas E. Kosinski - Tucson AZ, US
Shawn B. Harline - Tucson AZ, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

F16M 13/00

US Classification:

248560, 248603, 248605, 248618

Abstract:

Methods and apparatus for isolation system according to various aspects of the present invention comprise a plurality of elastic elements disposed in one or more planes between an equipment body and a mounting structure and are not symmetric about the center of gravity of the equipment body. The isolation system is configured to modally decouple vibration along one axis from other axes of vibration and provide an isoelastic mounting system in up to all six degrees of freedom.

Abstract:

A method of configuring a mount or of controlling sway in an object to be mounted includes configuring isolators of the mount to put a center of elasticity of the flexible mount at a desired height relative to a base of the mount. This desired distance may be at a location of expected minimum clearance between the object to be mounted and the structure expected to surround the object to be mounted and is the center of rotation of the flexible mount. The location of the center of elasticity also may be farther from the base than a center of mass or gravity of the object to be mounted. An equation relating the location of the center of elasticity as a function of isolator material properties and of angle between the isolators and the base may be used to analytically predict the location of the center of elasticity and the center of rotation.

Abstract:

An ultra-low distortion loudspeaker is described. The ultra-low distortion, on the order of 0.1% THD (total harmonic distortion) or less, is achieved by novel means. The signal from a typical preamplifier, i.e., line level signal, is fed into an ultra-low distortion, high order band-pass filter, the band-pass filter splitting the component frequencies into various bands. Secondly, the output of each band, or group of bands, is then input to an ultra-low distortion power amplifier, each driving an individual acoustic transducer. The band-pass filters, power amplifiers, and acoustic transducers, along with a suitable enclosure(s), comprise an ultra-low distortion integrated loudspeaker system.
