US Patent:

7164768, Jan 16, 2007

Filed:

Jun 21, 2001

Appl. No.:

09/886868

Inventors:

J. Richard Aylward - Ashland MA, US
Erik E. Anderson - San Mateo CA, US

Assignee:

Bose Corporation - Farmingham MA

International Classification:

H04R 5/00

US Classification:

381 22, 381307, 381 17

Abstract:

A method for processing and transducing audio signals. An audio system has a first audio signal and a second audio signal that have amplitudes. A method for processing the audio signals includes dividing the first audio signal into a first spectral band signal and a second spectral band signal; scaling the first spectral band signal by a first scaling factor proportional to the amplitude of the second audio signal; and scaling the first spectral band signal by a second scaling factor to create a second signal portion. Other portions of the disclosure include application of the signal processing method to multichannel audio systems, and to audio systems having different combinations of directional loudspeakers, full range loudspeakers, and limited range loudspeakers.

Inventors:

Erik Ossian Anderson - Tumwater WA, US
Wade Andrew Pfeiffer - Mercer Island WA, US

Assignee:

SHTC Holdings LLC - Montesano WA

International Classification:

G06F 15/173

Abstract:

A method and apparatus to compare a control article against a test article to support a product or service is disclosed. A client indicates a selection of the test article to be compared with the control article. The articles are fed to multiple end users in response to requests from the end users. The requests or responses are tracked to determine whether the control article or test article has more negative or positive responses. The control article may then be replaced with the test article as a primary article to support the product or service if the test article has a predetermined amount of positive or negative responses when compared with the control article to increase efficiency in supporting the product or service.
