BTech News and Recent Project Updates:

July 2014: BTech Acoustics announces it has received orders for its widely adopted BT-2RCL and 2RCL-OS underwater acoustics modem transducers. The Woods Hole Oceanographic Institute (WHOI) and Ocean Server Inc placed orders for integration with their micromodem and Iver2 vehicles respectively.

July 2014: BTech Acoustics wins a development/demonstration contract for its new design of a Deep Water USBL (Ultra-Short Base-Line) directional receiver. BTech Engineers are working closely with acoustics group at Woods Hole Oceanographic Institute (WHOI) and will field test a prototype late this summer. The new directional USBL sensor will extend operation at depth and the company is working on devices with full-ocean depth capability.

June 2014: SBIR Phase I awarded to BTech Acoustics LLC for (N141-026) Innovative Velocity Sensors

The Office of Naval Research (ONR) has award a Phase I SBIR contract to BTech Acoustics for the design and development of an improved Acoustic Accelerometer for naval applications. The researchers at BTech have 15 years of experience working on Pressure Gradient and Acoustic Motion Sensors (PGAMS) and accelerometers for hull and towed applications. The company is also exploring commercial applications of these highly sensitive sensors. BTech is improving the sensor technology with innovative improvements in sensor design and investigation of alternative piezoelectric materials including single crystal PMN-PT.

May 2014: SBIR Phase I awarded to BTech Acoustics LLC for (N141-066) Shear-Mode SONAR Transducer for Deep Submergence

The Office of Naval Research (ONR) has award a new Phase I SBIR contract to BTech for the design and development of improved Shear-Mode SONAR transducers for naval applications. The researchers at BTech are working on depth/pressure compensation designs to extend operational depth of the novel shear mode acoustic projectors with alternative piezoelectric materials including single crystal PMN-PT.

May 2014: BTech founder David A. Brown was inducted as a Fellow of the Acoustical Society of America (ASA) on May 7th in Providence, RI. His citation read for "contributions to fiber-optics and piezoelectric transduction science and leadership in acoustics education." Dr. Brown is Founder of the sonar development company BTech Acoustics LLC, Associate Editor of the Journal of the Acoustical Society of America (JASA), and a Professor of Engineering at the University of Massachusetts Dartmouth,.  The ASA, founded in 1929, is an international non-profit society dedicated to the advancement of Acoustics and all its disciplines (www.acousticalsoicety.org) and is affiliated with the American Institute of Physics.
