With the advent of device-assisted enteroscopy (DAE) in early 2000s, endoscopic access to entire small bowel is possible nowadays (1). And yet, there still room for improvement. Total remains a time-consuming procedure, often combining antegrade (oral) and retrograde (anal) approach with only reasonable chance obtain complete endoscopy (2). Therefore, aim go faster, deeper perform more advanced...

Active and sustainable commuting has a positive impact not only on the environment but also individuals’ health. A shift from using unsustainable motorized transport modes to active alternatives (cycling, walking public transport) is desirable. To enable such shift, it important raise awareness call for joint efforts by individuals, employers, planning practitioners decision-makers. In ActNow...

An understanding of adverse incidents and injuries sustained by active wheelchair riders, who live and work in the mainstream of society, is needed to improve safety via wheelchair design, selection, and configuration. We interviewed 109 riders who had experienced incidents, in order to identify the causes of incidents and injuries they suffered. Participants reported n = 253 incidents (53% in ...

Power wheelchair users may present secondary impairments that inhibit effective joystick control. Accordingly, driving assessments are needed to ensure the safety of both the drivers and their surroundings. We introduce a quantitative method to evaluate power wheelchair driving performance using the Markov decision process. Our dynamic, stochastic approach supplements previous quantitative eval...

Eyes base Electric Wheel Chair Control: EBEWC is proposed. The proposed EBEWC is controlled by human eyes only. Therefore disabled person can control the EBEWC by themselves. Most of the computer input system with human eyes only consider in specific condition and does not work in a real time basis. Moreover, it is not robust against various user races, illumination conditions, EWC vibration, a...

OBJECTIVES To determine the driving characteristics of electric-powered wheelchair users during unrestricted community activities and to compare the activity levels among an active group and a group of regular users. DESIGN Multisite engineering evaluation of electric-powered wheelchair driving activity during unrestricted community mobility. SETTING Data were collected in the communities o...

Service robotics is a new, emerging domain in robotics, characterised by enthusiasm, diverseness, and emerging industry. The paper presents modular and interacting obstacle avoidance, and navigation subsystems. The obstacle avoidance system is older, so there are practical experiences of its application to electric wheelchairs, which are explained. Ongoing work with the navigation unit is revie...

Assistive technology (AT) devices enable people with disabilities to function in multiple contexts and activities. The usability of such devices is fundamentally indicative of the user's level of participation in multiple roles and occupations. Seventy people who used power wheelchairs were interviewed using a novel tool, the Usability Scale for Assistive Technology (USAT). The USAT uses a huma...

This study determined the driving characteristics of wheelchair users during power wheelchair soccer games. Data for this study were collected at the 28th and 29th National Veterans Wheelchair Games. Nineteen veterans who were 18 years or older and power wheelchair soccer players completed a brief demographic survey and provided information about their power wheelchairs. A customized data-loggi...

An Ackerman steering linkage for short wheelbase, four-wheel vehicles has been developed. The linkage coordinates the steering angle of each wheel through a range of 180 degrees with minimal misalignment between wheels. Control of steering angles is accomplished using a single linear actuator. Control complexity is lower compared to four-wheel systems using individually controlled steering actu...
