The Untied States Department of Energy is engaged in the research, development and deployment of PHEV technology through the “Advanced Vehicle Testing Activity.” In this program, data has been collected from a Prius PHEV converted by Hymotion using industry standard dynamometer testing procedures and from in-use operation of fleets. Differences in fuel-only consumption rates observed in the on-...

OBJECTIVE The objective was to determine the reliability of a portable forearm strength hydraulic dynamometer with a doorknob handle and assess its validity compared with a Cybex 6000 (Cybex International, Inc., Medway, MA) isometric torque assessment. METHOD Eighteen volunteers (with a total of 30 forearms) participated in this one-session methodological study to determine the intra- and int...

This paper addresses the problem of electronic emulation of both linear and nonlinear mechanical loads using a vector-controlled induction machine dynamometer. It is shown that a basic emulation scheme where the dynamometer torque demand is derived from the inverse dynamics of the emulated load is not generally viable, especially if the emulated load is part of a closed-loop speed control syste...

[Purpose] This study aimed to determine the reliability and validity of our standing balance assessment index using a hand-held dynamometer (the hand-held dynamometer assessment index) in stroke patients. [Subjects and Methods] The participants were 60 stroke patients with impaired standing balance. Intrarater and interrater reliabilities were evaluated employing the intraclass correlation coef...
