The Development of the Differential MEMS Vector Hydrophone
To solve the problem that MEMS vector hydrophones are greatly interfered with by the vibration of the platform and flow noise in applications, this paper describes a differential MEMS vector hydrophone that could simultaneously receive acoustic signals and reject acceleration signals. Theoretical and simulation analyses have been carried out. Lastly, a prototype of the differential MEMS vector ...
متن کاملResearch of DOA Estimation Based on Single MEMS Vector Hydrophone
The MEMS vector hydrophone is a novel acoustic sensor with a "four-beam-cilia" structure. Based on the MEMS vector hydrophone with this structure, the paper studies the method of estimated direction of arrival (DOA). According to various research papers, many algorithms can be applied to vector hydrophones. The beam-forming approach and bar graph approach are described in detail. Laboratory tes...
متن کاملDesign, fabrication, and preliminary characterization of a novel MEMS bionic vector hydrophone
According to the auditory principle of fish’s lateral line organ, a novel microelectromechanical systems (MEMS) bionic vector hydrophone used for obtaining vector information of underwater sound field is introduced in this paper. It is desirable that the application of MEMS-based piezoresistive effect and bionics structure may improve the low-frequency sensitivity of the vector hydrophone as we...
متن کاملA Bio-Inspired Integration Method for Object Semantic Representation
We have two motivations. Firstly, semantic gap is a tough problem puzzling almost all sub-fields of Artificial Intelligence. We think semantic gap is the conflict between the abstractness of high-level symbolic definition and the details, diversities of low-level stimulus. Secondly, in object recognition, a pre-defined prototype of object is crucial and indispensable for bi-directional percepti...
متن کاملA H∞ loopshaping approach for autonomous bio-inspired visual navigation in three-dimensional urban environments
The insect visuomotor system combines a lightweight and high bandwidth sensor with fast processing algorithms for efficient information extraction that enables autonomous navigation in complex, obstacle laden environments. In this paper, an H∞ loop shaping controller synthesis framework is introduced to analyze an information extraction approach from patterns of optic flow based on analogs of w...
