Predictive maintenance predicts the system health, based on the current condition, and defines the needed maintenance activities accordingly. This way, the system is only taken out of service if direct evidence exists that deterioration has actually taken place. This increases maintenance efficiency and productivity on one hand, and decreases maintenance support costs and logistics footprints on the...
Atomic force microscopes (AFM) provide high resolution images of surfaces. In this paper, we focus on an interferometry method for estimation of deflections in arrays of cantilever in quasi-static regime. We propose a novel complete solution with a least square based algorithm to determine interference fringe phases and its optimized FPGA implementation. Simulations and real tests show very good results...
Atomic force microscopes (AFM) provide high resolution images of surfaces. In this paper, we focus our attention on an inter ferometry method for deflection estimation of cantilever arrays in quasi-static regime. In its original form, spline interpolation was used to determine interference fringe phase, and thus the deflections. Computations were performed on a PC. Here, we propose a new complete...
We focus here on the optimization of a sensing system based on SAW resonators inserted in an oscillation loop for very high accuracy measurements. We use single-port SAW resonators built on AT Quartz, inserted in a Colpitts oscillator loop operating near 434 MHz. A reciprocal counter then is implemented on a FPGA platform which communicates the counting result to the ZigBee transmission system using...
