In this paper we propose a pattern adaptive keypad interface for in-vehicle information system. The keypad interface recommends the estimated input sequence to fit the user’s preference based on individual model of operation pattern. Pattern (shape) of button switches corresponding to the estimated input sequence is actively reformed. Button switches are displayed tactilely and visually. Finger image is shown on the monitor in real-time in order to guide input operation on the tactile input devi(..)

AN EMBEDDED WIRELESS SYSTEM FOR ESTIMATING THE EXPOSITION RISK IN FIRST EMERGENCY MANAGEMENT

Cesare Alippi/ Cristian Galperti

In this paper we propose the design of a wearable embedded system1 for wirelessly delimiting an hazardous area during emergency, alerting the rescue operators when entering in it and measuring the consequent exposition time. (The dangerous area is previously identified, e.g., through suitable instrumentation). The suggested approach, which is identically effective in indoor and outdoor environments, significantly extends existing solutions by not requiring any absolute position information for d(..)

CO2 sensing characteristics of Sm1-xBaxCoO3 (x = 0, 0.1, 0.15, 0.2) nanostructured thick film

G.N. Chaudhari/ P.R. Padole/ S.V. Jagatap/ M.J. Pawar

SmCoO3 gas sensor has been developed with high sensitivity for CO2 gas by doping Ba. Nanostructured SmCoO3 and Sm1-xBaxCoO3 (x = 0, 0.1, 0.15, 0.2) were obtained by EDTAGlycol method. The operation temperature falls and sensitivity increases from 425 to 370OC when Ba concentration in SmCoO3 changes from x = 0 to x = 0.1. Ag impregnation over Sm0.9Ba0.1CoO3 sensor, on exposure to CO2 at about 360OC showed an increased sensitivity as well as the response time also decreases. The possible CO2 sensi(..)

PV Maximum Power Point Tracking Through Pyranometric Sensor: Modelling and Characterization

A. Lay-Ekuakille/ G. Vendramin/ A. Fedele/ L. Vasanelli/ A. Trotta

Solar trackers represent apparatuses that may significantly improve electric power production of photovoltaic panels. For detecting solar position, the trackers use different sensors (e.g. photoresistor, photodiode receiver, phototransistor, etc..). This research proposes an alternative way, the use of the sensor par excellence for retrieving solar radiation; the pyranometer. A design and tests have been performed in order to show the improvements. A comparison has been made between this alterna(..)

TIME-VARYING-GEOMETRY OBJECT SURVEILLANCE USING A MULTI-CAMERA ACTIVE-VISION SYSTEM

Matthew Mackay/ Robert G. Fenton/ Beno Benhabib

This paper presents a novel, agent-based sensing-system reconfiguration methodology for the recognition of time-varying-geometry targets (objects or subjects). A multi-camera active-vision system is used to improve form-recognition performance by selecting near-optimal viewpoints along a prediction time horizon. The proposed method seeks to maximize the target visibility in a cluttered, dynamic environment. Simulated experiments clearly show a tangible potential performance gain.

COOPERATIVE MULTI TARGET TRACKING USING MULTI SENSOR NETWORK

Ahmed M. Elmogy/ Fakhreddine O. Karray

Sensors provide a key feedback link allowing robotic and autonomous systems to react to their environments. Without this feedback, robotic and autonomous systems will operate in an uncontrolled manner, since they don’t have the ability to perceive and respond to their environments. The limited capabilities of static sensors especially in complex applications and environments force the use of multiple sensors operating dynamically. This paper addresses the development of multiple objects tracking(..)

HUMANITARIAN DEMINING ROBOT GRYPHON CURRENT STATUS AND AN OBJECTIVE EVALUATION

Edwardo F. Fukushima/ Marc Freese/ Toshiaki Matsuzawa

Mechanical systems or robots to assist landmine detection are expected to greatly improve quality of humanitarian demining tasks. These new systems could provide: i) safer operation; ii) advanced methods for automatic target recognition and discrimination; iii) consistent performance with less influence of “human-factors”; iv) better detection performance, i.e., higher probability of detection (POD) and lower false alarm rate (FAR); among others. However, despite many research/development effort(..)

RAILWAY WHEELSET PARAMETER ESTIMATION USING SIGNALS FROM LATERAL VELOCITY SENSOR

H. Selamat/ A. J. Alimin/ Y. M. Sam

A type of parameter estimation technique based on the linear integral filter (LIF) method, the least-absolute error with variable forgetting factor (LAE+VFF) estimation method, is proposed in this paper to estimate the railway wheelset parameters modelled as a time-varying continuous-time (C-T) system. The inputs to the parameter estimator are the control signal and the railway wheelset system output, which is the wheelset’s lateral velocity. The algorithm includes an instrumental variable (IV) (..)

MEASURING DYNAMICS OF SCATTERING CENTERS IN THE OCULAR FUNDUS

Luigi Rovati/ Stefano Cattini/ Francesco Viola/ Giovanni Staurenghi

The study is focused on the analysis of the diffusing-wave-spectroscopy signal recorded invivo on the ocular fundus of a rabbit eye. The motion of the scattered sites was measured as a function of the pressure exerted by a Goldmann contact lens and during the moderate temperature increase induced by a therapeutic laser diode. Temporal fluctuations of the signal revel motion of molecules and thus changes in tissues temperature and chorioretinal blood velocity. Experimental results show the abilit(..)
