Improvement of control cable system of trans-humeral body-powered prostheses.
For the purpose of improving the efficiency of a body-powered prosthesis, a control cable system was developed which uses a pulley and a cable housing which includes a highly slippery plastic liner. Improvements were also made to the harness. In this paper, the mechanism of these systems is firstly described and then, the results of a clinical evaluation test of a practical model is presented a...
متن کاملHigh Cable Forces Deteriorate Pinch Force Control in Voluntary-Closing Body-Powered Prostheses
BACKGROUND It is generally asserted that reliable and intuitive control of upper-limb prostheses requires adequate feedback of prosthetic finger positions and pinch forces applied to objects. Body-powered prostheses (BPPs) provide the user with direct proprioceptive feedback. Currently available BPPs often require high cable operation forces, which complicates control of the forces at the termi...
متن کاملMyo-electric Control of Powered Prostheses.
The possibility of using myo-electric potentials for the control of powered prostheses is not a new one. It was probably first suggested as long ago as 1947 by the late Professor Norbert Weiner (1963), and was first achieved in Guy’s Hospital in 1955 by Battye, Nightingale and Whillis. More recently the idea has received considerable publicity because of the introduction in Russia of an electri...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولFatigue-free operation of most body-powered prostheses not feasible for majority of users with trans-radial deficiency
BACKGROUND Body-powered prostheses require cable operation forces between 33 and 131 N. The accepted upper limit for fatigue-free long-duration operation is 20% of a users' maximum cable operation force. However, no information is available on users' maximum force. OBJECTIVES To quantify users' maximum cable operation force and to relate this to the fatigue-free force range for the use of bod...
