Tomorrow's Technologies
Biomimetics refers to manmade systems that mimic biology. Our patented acoustic processing technology is based on signal processing algorithms for human hearing. The algorithms can be realized in both hardware and software for various applications. The algorithms have been implemented in discrete analog, analog VLSI, and several digital platforms. The current implementation of BioMimetic Systems' Acoustic Direction Finding (ADF) technology is a hybrid of analog and digital circuitry. Full custom, low power, analog VLSI implementations are being explored as university research through the Electrical and Computer Engineering (ECE) department at Boston University.
The
algorithms can be programmed to discriminate multiple classes of
acoustic signatures. The system can detect sound sources, both
continuous or transient, over a broad range of frequencies. The
algorithms selectively localize specific sound sources in azimuth and
elevation based on acoustic signatures. The biomimetic aspects of the
hardware and algorithms enable the system to detect and localize in
high background noise and reverberant environments with robust
performance. Currently, there are research projects at Boston
University using these algorithms to improve hearing aid design and
cochlear implant performance. (Visit www.bu.edu/vnns

Applications
There are many applications for acoustic recognition and direction finding. In the military and law enforcement sectors the sensors can be deployed on many platforms to provide mission specific information. Some uses include unmanned ground sensors, helmet mounted sniper detection, robotic platforms, vehicle mounted sensors, and urban gunshot detection.
The next generation of sensors will lower the size and power requirements, enabling many more platform possibilities.
