“…Besides, the thrust performance directly relates to the accuracy of manufacture. Research indicates that the maximum thrust could decrease by ~17% when the manufacture errors are over 10% [ 5 ]. The first is that the key to accomplish precise manufacture of three-dimensional micro structures begins with solving the three-dimensional microscale sensing problems [ 1 ].…”

Three-dimensional micro-scale sensors are in high demand in the fields of metrology, precision manufacturing and industry inspection. To extend the minimum measurable dimension and enhance the accuracy, a tapered four-cores fiber Bragg grating (FBG) probe is proposed. The sensing model is built to investigate the micro-scale sensing characteristics of this method and the design of the tapered stylus is found to influence the accuracy. Therefore, a π/2 phase-shift point is introduced into the FBGs comprised in the probe to suppress spectrum distortion and improve accuracy. Then, the manufacturing method based on capillary self-assembly is proposed to form the probe and the critical length to form a square array for four cylindrical fibers is verified to be effective for the tapered fibers. Experimental results indicate that the design of the tapered stylus can extend the minimum measurable dimension by twofold and has nearly no influence on its sensitivity. The three-dimensional measurement repeatability is better than 31.1 nm and the stability is better than 200 nm within once measuring process. Furthermore, the measurement precision of the three-dimensional micro-scale measurement results is less than 150 nm. It would be widely used in measuring micro-scale features for industry inspection or metrology.

“…The quality-fault tolerance problem can also be looked as checking whether the given system is failbounded [5], [13]. [14] evaluates the dependability of a failbounded jet engine control system with respect to single event upsets (SEUs) by injecting single bit-flip faults. Most of the previous work is not applicable during early design phases such as operation level and also does not consider simultaneous faults at multiple locations in the design which is necessary due to the independent nature of their causes.…”

This work presents a static-analysis based method for analyzing the robustness of a given embedded control system design, in the presence of quality-faults in sensors, software components, and inter-connections. The method characterizes the individual components of the system by storing the relations between the precision of inputs and the precision of outputs in what we call, lookup tables (LUTs). A network of LUTs thus formed which represent the given control system is converted into a satisfiability modulo theory (SMT) instance, such that a satisfying assignment corresponds to a potential counterexample (the set of quality-faults which violate the given fault-tolerance requirements) or hot-spot in the design. Hotspots obtained in this manner are counter-verified through simulation to filter the false-positives. Experimental results on the fault-tolerant fuel controller from Simulink automotive library demonstrate the efficacy of the proposed approach.
