The Americans with Disabilities Act (ADA) specifies guidelines covering the securement system and environment for wheeled mobility device (WhMD) passengers on the public bus system in the United States, referred to as the wheelchair tiedown and occupant restraint system (WTORS). The misuse or disuse of the WTORS system can be a source of injury for WhMD passengers riding the buses. The purpose ...

The motorized microdrive was designed primarily by Michale Fee. My contributions to the design of the instrument include work on the split connector that allows the motor assembly to be removed from the microdrive barrel, the lateral positioner that provides limited xy positioning of the electrodes, and some of the electrical modifications to the Sutter MP-285 that is used to remotely position ...

Mopeds are not subject to the same laws and jurisdiction as cars or motorcycles, including the requirement of a driver's license. We undertook this study to examine the influence of alcohol (ETOH) on moped crashes. We retrospectively reviewed adult moped injuries compared with motor vehicle crashes (MVCs) and motorcycle crashes (MCCs) from 1995 through 2006. Demographics, severity of injury, mo...

We have developed fully motorized optical-resolution photoacoustic microscopy (OR-PAM), which integrates five complementary scanning modes and simultaneously provides a high imaging speed and a wide field of view (FOV) with 2.6 μm lateral resolution. With one-dimensional (1D) motion-mode mechanical scanning, we measured the blood flow through a cross section of a blood vessel in vivo. With two-...

A robotic manipulator has been mounted to an electric wheelchair to assist people with disabilities. Particular emphasis has been given to the constraints and requirements for wheelchair mounting.

BACKGROUND The goal of this observational study was to determine factors predictive of the type of powered mobility prescribed to veterans with disability. MATERIAL/METHODS A retrospective chart review was conducted for all veterans (n=170) who received powered mobility from a designated power mobility clinic. Logistic regression analysis was used to determined factors predictive of the type ...

PURPOSE The aim was to investigate outcomes of powered wheelchair and scooter interventions after 4-months and 1-year use regarding need for assistance when moving around, frequency of mobility-related participation, easiness/difficulty in mobility during participation, and number of participation aspects performed in everyday life. METHOD The study was a prospective cohort study, using an in...

As one of the leading method of electric wheelchairs, platoon driving using Adaptive Cruise Control (ACC) has been proposed to keep constant time-headway. The platoon driving system has been widely used assuming straight roads that has good visibility, but has not been used in narrow corridor. While, the gross weight of wheelchair changes drastically depending on passenger’s weight. In this pap...

Active travel (AT) has the potential to integrate with, or in some cases substitute for, trips taken by motorized transportation. In this paper we review relevant research on AT outcomes address of and emerging data sources supporting transport paradigm shift toward AT. Our analysis identifies physical, mental, built physical environmental, monetary, societal outcomes. Traditional methods used ...
