US Patent:

8219391, Jul 10, 2012
Filed:

Nov 6, 2006
Appl. No.:

11/593836
Inventors:

Robert David Preuss - Sagamore Beach MA, US
Darren Ross Fabbri - Arlington MA, US
Daniel Ramsay Cruthirds - Cambridge MA, US
Assignee:

Raytheon BBN Technologies Corp. - Cambridge MA
International Classification:

G10L 11/06
G10L 19/00
G10L 21/02
G10L 15/20
G10L 15/06
G10L 21/04
US Classification:

704214, 704219, 704223, 704226, 704227, 704228, 704233, 704243, 704244, 704500, 704501, 704502, 704503
Abstract:

Presented herein are systems and methods for processing sound signals for use with electronic speech systems. Sound signals are temporally parsed into frames, and the speech system includes a speech codebook having entries corresponding to frame sequences. The system identifies speech sounds in an audio signal using the speech codebook.

US Patent:

8320217, Nov 27, 2012
Filed:

Dec 2, 2009
Appl. No.:

12/629761
Inventors:

James Edwin Barger - Winchester MA, US
Richard James Mullen - Needham MA, US
Daniel Ramsay Cruthirds - Cambridge MA, US
Ronald Bruce Coleman - Arlington MA, US
Assignee:

Raytheon BBN Technologies Corp. - Cambridge MA
International Classification:

G01S 3/80
US Classification:

367127
Abstract:

The systems and methods described herein relate to an airborne shooter detection system having a plurality of sensors coupled to the body of an aircraft such as a helicopter. The sensors are arranged to receive shockwave-only signals. The received signals are analyzed to determine an unambiguous shooter location. The analysis may include measuring the arrival times of the shockwaves of projectiles at each of the sensors, determining the differences in the arrival times among sensors, computing a set of ambiguous solutions corresponding to a shooter, and clustering this set of solutions to determine the unambiguous shooter location. The systems and methods described herein may also be used to determine if multiple shooters are present, and subsequently determine the shooter locations for each of the multiple shooters.

US Patent:

20060184362, Aug 17, 2006
Filed:

Feb 15, 2006
Appl. No.:

11/355777
Inventors:

Robert Preuss - Sagamore Beach MA, US
Darren Fabbri - Arlington MA, US
Daniel Cruthirds - Cambridge MA, US
Assignee:

BBN Technologies Corp. - Cambridge MA
International Classification:

G10L 15/20
US Classification:

704233000
Abstract:

Presented herein are systems and methods for generating an adaptive noise codebook for use with electronic speech systems. The noise codebook includes a plurality of entries which may be updated based on environmental noise sounds. The speech system includes a speech codebook and the adaptive noise codebook. The system identifies speech sounds in an audio signal using the speech and noise codebooks.
