Assistive robotics are playing a vital role in advancing the quality of life for disable people. There exist wide range of systems that can control and guide autonomous mobile robots. The objective of the control system is to guide an autonomous mobile robot using the movement of eyes by means of EOG signal. The EOG signal is acquired using Ag/AgCl electrodes and this signal is processed by a m...

we find an explicit expression of the tutte polynomial of an $n$-fan. we also find a formula of the tutte polynomial of an $n$-wheel in terms of the tutte polynomial of $n$-fans. finally, we give an alternative expression of the tutte polynomial of an $n$-wheel and then prove the explicit formula for the tutte polynomial of an $n$-wheel.

A tetraplegic patient was able to induce midcentral localized beta oscillations in the electroencephalogram (EEG) after extensive mental practice of foot motor imagery. This beta oscillation was used to simulate a wheel chair movement in a virtual environment (VE). The analysis of electrocardiogram (ECG) data revealed that the induced beta oscillations were accompanied by a characteristic heart...

We have been developing Robotic Travel Aid (RoTA) “HARUNOBU” to guide the visually impaired in the sidewalk or campus. RoTA is a motor wheel chair equipped with vision system, sonar, differential GPS system, dead reckoning system and a portable GIS. We estimate the performance of RoTA in two viewpoints, the viewpoint of guidance and the viewpoint of safety. RoTA is superior to the guide dog in ...

Information and knowledge management were introduced in the engineering field to help product developers avoid "reinventing the wheel". As PDM and DMS systems manage the whole information about a developed product, no software systems for capturing, managing and analysis of the product development processes are available. This information is usually stored only in the mind of the involved engin...

The Center for Self-Organizing and Intelligent Systems at Utah State University has been engaged in a two year project to investigate the application of virtual reality and associated technologies as a means for assisting the disabled to steer and control motorized wheelchairs. There have already been several interesting investigations aimed at steering virtual wheelchairs in virtual, computer ...

On examination he had swollen, unstable, painless right elbow with weakness in hand. Active flexion was possible from 25 to 100 degrees with palpable and audible crepitation. Range of supination and pronation was severly restricted. There was weakness of the interosseous muscles and digital flexors of the ipsilateral hand. A sensory examination revealed loss of touch sensation in the area of ul...

Duchenne muscular dystrophy (DMD) is the most common hereditary neuromuscular disease affecting all races and ethnic groups, with a sex linked inheritance pattern of 1 in 3500 male births. The underlying genetic defect results in the loss of a structural protein called dystrophin that normally serves to provide mechanical stability during muscle contraction. As a result of this loss, there is e...
