Long QT syndrome (LQTS) is characterized by abnormalities in cardiac repolarization that lead to prolongation of the electrocardiographic (ECG) QT interval. Mutations in the human ether-a-go-go-related gene (HERG, KCNH2) cause the chromosome 7-linked LQT2 form of congenital LQTS, which is characterized by a prolonged QT interval and a bifid T-wave with an(More)
In order to make full use of the ability of the low impact docking mechanism to reduce the contact force in the docking process, the impedance control strategy is designed. And then a kind of parameter adjusting flow is proposed for the impedance controller based on the influence rules of the target impedance. To perform a low impact docking mission unaware(More)
In order to solve the violent collision and energy consumption problems of conventional space docking mechanism in the docking process, we developed a set of low impact docking mechanism based on impedance control. The docking mechanism adopts the peripheral docking type, the active end of which is a 6-UPS parallel mechanism which is driven by six electric(More)
