Objetives

The objective of the project is to explore solutions to data reduction techniques for monitoring applications in the scope of the applications focused by partners of the USES² consortium, i.e., with a focus on acoustic/ultrasonic sensors. Through tight interaction with the corresponding partners, a thorough comprehension of the relevant sensor modalities should be established so that a clear understanding of relevant and irrelevant parts of the measurement signals is achieved. Based on this, concepts and architectures for data reduction should be researched. This process follows three basic steps: (a) software-based data reduction (post acquisition), (b) on board data reduction close to the sensor (e.g. FPGA-based), (c) on-chip data reduction (via suitable custom electronic design). The concept will be evaluated using concrete applications within the USES² consortium.
