An efficient real-time speed limit sign recognition system could provide significant benefits for realizing advanced driver assistance systems (ADAS). This paper presents an approach for real-time recognition of U.S. speed limit sign. Detection of speed limit sign is carried out using shape and intensity information after identifying the candidate regions as maximally stable extremal regions (MSERs)...
Tense thin-film polycrystalline (poly-) Si torsion bars are advantageous in behaving as compliant springs against the twisting motion of electrostatically low-voltage-driven micromirrors. In this study, the nonlinear spring effect of the tense thin-film poly-Si torsion bar of a micromirror was characterised. The nonlinear spring effect of this torsion bar was explained theoretically, considering the...
The tense polycrystalline (poly-) Si torsion bar micromirror is advantageous to realize large rotation angle and stabilized temperature characteristics, simultaneously. In this paper, the hard spring effect of tense poly-Si torsion bar is characterized.
Realizing an optically flat surface during high-speed scanning is a crucial factor for the micromirror with large mirror plate. This paper presents the dynamic deformation analysis of stretched polycrystalline (poly-) Si membrane of flat and lightweight drum-type micromirror. The drum-type micromirror is realized using a tense poly-Si membrane across a rigid crystalline (c-) Si ring. The total peak-to-valley...
Currently, the concept of ergonomically designed workplace using 3D graphic mannequins is gaining wide acceptance among the design engineers. However, predicting the human operational feeling level (i.e., comfort or discomfort level) during an ergonomic analysis of a virtual work situation is still in immature level. The current study is an attempt in that direction. This paper presents an approach...
