For reducing the inconsistency of sensors' characteristics in laboratory and working conditions, calibration of an accelerometer with multicomponent inputs is introduced. After a review of current equipments which are capable of producing combined accelerations, we introduced a different apparatus which can offer simultaneous harmonic and constant linear accelerations. It consists of a vibration exciter...
This paper details the design and development of a device that can, through the mechanism of biofeedback, assist individuals undergoing rehabilitation for leg injuries. The device consists of two plates, a base plate which is fixed and a top plate on which the user stands and can be tilted. The two plates are separated by an automotive ball joint and four springs which provide a damping force. A high...
An approach suitable for calibrating the transverse sensitivity of accelerometer at low-frequency is presented in this work. The method proposed here employs the double turntable centrifuge as the apparatus to provide standard reference accelerations. Numerical simulation and experimental investigation are done to validate the method. Testing results of a single-axis inertial accelerometer are consistent...
Early warning systems (EWS) for the structural monitoring of buildings and structures have a notable impact for the safety of the same structures and of the populations. These systems have significantly increased with the availability of wireless sensor networks (WSNs) which represent a low cost, but a reliable solution, to perform the real-time monitoring task. The main goal of this work is the realization...
Functional electrical stimulation is a considerably new technology for stroke rehabilitation therapy of paralyzed limbs by actively stimulating the muscular nerve endings using controlled electrical impulses to produce meaning movements. This project involves development of a software system for complex control of the stimulation system. It is integrated with the feedback from motion sensors to produce...
This paper presents the design and implementation of a system of accelerometer-based hand gesture recognition. This system will be embedded within a modern remote control to improve human-machine interaction in the context of digital TV of Argentina. As the recognition of hand gestures is a pattern classification problem, two techniques based on artificial neural networks are explored: multilayer...
