The aim of this qualitative study was to gain an understanding of what people who use wheeled mobility devices (WMDs; e.g., manual and power wheelchairs, and scooters) identify as environmental barriers to community participation in cold weather climates, and to explore recommendations to overcome environmental barriers to community participation. Researchers conducted an online asynchronous fo...

The objective of this work is to model the pilotvehicle system made up of a person with disability and of an electric wheelchair. This modelling must induce an objective analysis method of the pilot-wheelchair couple in order to help to personalize the parameters of the vehicle on the one hand and to evaluate the interest of new functionalities on the other hand. After a review of the literatur...

PURPOSE To explore the experiences of using an electric wheelchair in daily living. METHODS Fifteen participants, eight women and seven men, living in different parts of a Nordic country were interviewed. The interviews were conducted in the home or at the workplace. Open-ended questions were used. The data were collected and analyzed according to the grounded theory. RESULTS Analysis resul...

A new infinitely variable automatic transmission called the RESATRAN that automatically changes its speed ratio in response to load torque being transmitted is presented. A prototype has been built and tested on a conventional three-wheeled electric motor propelled wheelchair. It is shown theoretically that more than 50 percent reduction in power during hill climbing may be expected when a tran...

A sustainable transport system must meet the mobility and accessibility needs of people by providing safe and environmentally friendly modes of transportation. This is a complex and difficult task in the mega-cities of developing countries because the needs of people belonging to various income groups are not only different, but also often conflicting in nature. For example, if a large section ...

We present a miniature motorized endoscopic probe for Optical Coherence Tomography with an outer diameter of 1.65 mm and a rotation speed of 3,000-12,500 rpm. This is the smallest motorized high speed OCT probe to our knowledge. The probe has a motorized distal end which provides a significant advantage over proximally driven probes since it does not require a drive shaft to transfer the rotati...

Original scientific paper Reducing the manufacturing time is the trend of high precision manufacturing, and the precision of a work-piece is very important for the manufacturing industry. The high-speed motorized spindle is the most critical part and becoming more widely used in the machine tool at present, and its precision may affect the overall performance of high-speed cutting. Most of the ...

A simple test rig was developed to measure the capacity of the lead-acid gel-electrolyte batteries used to power wheelchairs. Results of 166 tests revealed a wide scatter of battery life with different users and also showed that, in many cases, the two batteries used in a wheelchair became unequal in charge capacity after some time in use. It is recommended that pairs of batteries should be cha...

OBJECTIVE The objective of this study was to systematically review the literature to assess the efficacy of nonsurgical spinal decompression achieved with motorized traction for chronic discogenic lumbosacral back pain. DESIGN Computer-aided systematic literature search of MEDLINE and the Cochrane collaboration for prospective clinical trials on adults with low back pain in the English litera...
