TECHNOLOGY TRANSFER OPPORTUNITY --Acoustic Beamforming Array: LAR-17985-1

NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a microphone array that identifies the locations and strengths of acoustic sources using sensors that are "self-calibrated" with closed-loop feedback control. This results in an array that can be considered "self-matching." Beamforming microphone arrays typically consist of tens to hundreds of microphones. The location of an acoustic source can be determined by exploiting the acoustic wave propagation delays from the source to each of the microphones. For the system to be accurate each microphone must be calibrated to account for varying magnitude and phase frequency responses. Manual calibration is time-consuming and may need to be repeated regularly to take into account effects such as heat and humidity. This innovation removes such time-consuming calibration and provides more accurate results. NASA is seeking to license this technology commercially. US Patent 8,848,942. To express interest in this opportunity, please respond to [email protected] with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information. Please also provide the nature of your interest in the technology along with a brief background of your company. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at http://technology.nasa.gov/ . These responses are provided to members of NASA Langley’s Office of Strategic Analysis and Business Development “OSACB” for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, OSACB will follow the required formal licensing process of posting in the Federal Register. No follow-on procurement is expected to result from responses to this Notice.
