Event-Based Sensing and Signal Processing in the Visual, Auditory, and Olfactory Domain: A Review

Mohammad-Hassan Tayarani-Najaran, Michael Schmuker
2021 Frontiers in Neural Circuits  
The nervous systems converts the physical quantities sensed by its primary receptors into trains of events that are then processed in the brain.  ...  The key principle pursued in neuromorphic sensing is to shed the traditional approach of periodic sampling in favor of an event-driven scheme that mimicks sampling as it occurs in the nervous system, where  ...  Future research is therefore expected to focus on developing machine learning techniques that are specifically designed for event-based systems.  ...

2004 ACM Transactions on Embedded Computing Systems  
This analysis is done using different transmission workloads, whose control parameters include the interframe spacing, density of nodes, transmit power level, transmitter-receiver distance, area of deployment  ...  Because ultra-wideband signals have much higher signal bandwidth than narrow-band signals, they can penetrate through walls and other obstacles, thereby avoiding non-line-of-sight conditions.  ...  The aim of this experiment is to isolate and study the impact of beacon density on the Random, Max and Grid beacon placement algorithms. At low densities (  ...
