Design and Synthesis of 6α-Corticosteroid Haptens and Their Bovine Serum Albumin (BSA) Conjugates

Chinese Chemical Letters 2003年第3期14卷 259-262页

The site of attachment of protein carrier to corticosteroids has great influence on the specificity of produced antibody. In order to obtain highly specific and accurate antibodies for bioimmunoassay determination of cortisol, different tether lengths of 6-corticosteroid haptens and their BSA conjugates were designed and synthesized.

Power-Assisted Cart Control Method with Motor Torque Limiter Based on Prediction of Torque Saturation

引用

Journal of Energy and Power Engineering 2012年第8期6卷 1349-1357页

作者： norihiro kobayashi Takayuki Tanaka Shun' ichi Kaneko Graduate School of Information Science and Technology Hokkaido University Sapporo 060-0814 Japan

In this article, a method to control power-assisted carts with motor torque limiter that achieves the desired load-reduction ratio even if torque saturation occurs, is proposed to reduce the size and power consumption of power-assist systems. This method uses the ratio of the assist-force impulse to the operator-force impulse as an indicator for evaluating proposed method. Proposed method predicts the needs of the operator and delivers the desired load-reduction ratio by predicting operation. The results show that the target load-reduction ratio can be obtained with proposed control method and indicate that the target load-reduction ratio can be obtained with 80% force. By applying our proposed method, short available time of power-assisted carts will be improved.
