10 Awards Won

Phase 1 SBIR

Agency: Defense Health Program
Topic: OSD11-H11
Budget: 12/08/11 - 07/08/12

Tinnitus, along with hearing loss, are the two top service-related disabilities for veterans. It has been estimated that together the cost to the Veterans Administration is $1.5B annually. While hearing loss can readily be quantified, measures of tinnitus have remained highly subjective making quantitive assessments of occurrence and severity ...

Phase 1 SBIR

Agency: Navy
Topic: N111-066
Budget: 05/09/11 - 03/09/12

Acentech proposes to develop an underwater sound projector source that can be used for Low Frequency Long Range Acoustic Communications, and which is operational down to a depth of 1000 m. This transducer design incorporates new high output magnetostrictive materials that are robust, malleable and machinable, and which are arranged in ring fashi...

Phase 2 SBIR

Agency: Navy
Topic: N08-191
Budget: 06/09/10 - 06/08/11

The goal of this Phase II will be a full scale demonstration of an acoustic metamaterial cloak on a UUV-like vehicle. The design will be based on the Cummer-Schurig cylindrical solution for a perfect 2-D cloak surrounding a rigid cylindrical object. The first effort will be a theoretical task in conjunction with KSU to evaluate important issues ...

Phase 1 SBIR

Agency: Navy
Topic: N091-024
Budget: 05/06/09 - 11/06/09

The rejection of transient and broadband gunshot noise signals in the presence of speech has the problem that speech is also transient and broadband. Although adaptive filtering and/or matched filter rejection will have some application, additional characteristics that separate gunfire from speech are needed for optimal noise cancellation. This ...

Phase 1 SBIR

Agency: Navy
Topic: N08-191
Budget: 10/27/08 - 02/08/10

Acoustic cloaking the ability to direct sound completely around an object is an exciting possibility. Potential military applications include making underwater objects invisible to threat sonar and creating quiet zones where, for example, otherwise noisy manned underwater operations can be safely carried out or where battlefield noise can be...

Phase 2 SBIR

Agency: Navy
Topic: N07-076
Budget: 09/24/08 - 02/24/10

This proposal is concerned with two important aspects of sound as it affects divers; the ability to receive and send communications ( comms ), and the effects of ambient noise, particularly in construction and demolition activity. SCUBA divers wear a breathing apparatus and their ears are often flooded so that systems that occlude the ear canal...

Phase 1 SBIR

Agency: Navy
Topic: N07-076
Budget: 06/18/07 - 03/18/08

This proposal is concerned with the use of single crystal PMN-PT as a transducer element in underwater communication systems. The high sensitivity and strain capability of these materials makes them unusually appropriate for the demands of small size and high output needed in this application. Developments already underway as an element in activ...

Phase 2 STTR

Institution: Northeastern University

Agency: Army
Topic: A05-T025
Budget: 08/31/06 - 08/30/07

Knowing the kind(s) of machinery and equipment contained in a building and its approximate location prior to having to enter the building is a valuable asset to military operations, particularly in urban situations. The proposed system, called BIMLI (Bui

Phase 1 SBIR

Agency: Department of Health & Human Services
Topic:
Budget: 09/12/05 - 03/11/07

DESCRIPTION (provided by applicant): The project's long-term objective is to provide a capsule that will permit functional magnetic resonance imaging (fMRI) to be carried out on test animals conveniently without subjecting these animals to the stresses associated with the acoustic noise produced by MRI equipment. Such a capsule will facilitate ...

Phase 2 SBIR

Agency: Air Force
Topic: AF95-030
Budget: 07/10/96 - 07/10/98
PI: Hal Amick

This proposal would continue the effort that was initiated under the SBIR Phase I Contract F41624-95-C-9013. This previous study, which was completed in December 1995, investigated the feasibility of using a thin piezoelectric film bonded to the inner surface of an animal noise monitor (ANM) enclosure as an acoustic transducer capable of p...
