Objects Localization and Differentiation Using Ultrasonic Sensors 521 Objects Localization and Differentiation Using Ultrasonic Sensors

The most crucial problem for the mobile robot navigation is obstacles detection and their localization. The determination of obstacle position should be as accurate as possible in order to support robot self-localization procedures. In order to increase its efficiency the recognition of some feature of obstacles shapes should be done. The most advanced systems use laser range-finder and vision ...

Arbitrary Strain and Temperature Distribution Sensing Using Two FBG Pairs

We use two pairs of FBGs to perform simultaneous strain and temperature field measurements. The first pair of FBGs, comprising one uniform FBG and one chirped FBG, measures the strain and temperature fields, while the second pair of FBGs, also comprising one uniform FBG and one chirped FBG, measures the temperature field only. A genetic algorithm is applied to reconstruct the arbitrary strain a...

3D Gesture Acquisition Using Ultrasonic Sensors

Research and musical creation with gestural-oriented interfaces have recently seen a renewal of interest and activity at Ircam. In the course of several musical projects, issued either by from young composers enrolled in the Cursus of Composition and Computer Music or by guests artists, the Pedagogy and Creation departments of Ircam have proposed various solutions for gesture-controlled sound s...

Collaborative Sensing Using Sensors of Uncoordinated Mobility

Wireless sensor networks are useful for monitoring physical parameters and detecting objects or substances in an area. Most ongoing research consider the use of either fixedly deployed stationary sensors or sensors on mobile platforms traversing controlled paths, which incur substantial costs in either equipments or coordination efforts. In this paper, we consider a different sensing model usin...
