Patent number: 9769915Abstract: The invention relates to a drive arrangement in a spacecraft, comprising several drive units (TW1,TW2,TW3), several individually controllable drive units that can be continuously applied to a common, constant voltage potential (HV), and a control of the axial thrust in the respective drive units is achieved due to the fact that the production of plasma in the respective drive units is individually controlled. In particular, the time-variable control of the production of plasma occurs by the time-variable control of the flow of neutral working gas (AG) in the ionization chamber (IK).Type: GrantFiled: September 12, 2008Date of Patent: September 19, 2017Assignee: Thales Electronic Systems GmbHInventors: Hans-Peter Harmann, Norbert Koch, Guenter Kornfeld

Patent number: 9291650Abstract: A voltage sensor includes an insulator with mutually insulated electrodes embedded therein. The electrodes are coaxial and cylindrical and overlap axially along part of their lengths. They are mutually staggered and control the surfaces of electric equipotential such that there is a substantially homogeneous electric field outside the insulator and a substantially homogeneous but higher field within a sensing cavity within the insulator. A field sensor is arranged within the sensing cavity to measure the field. This design allows for the production of compact voltage sensors for high voltage applications.Type: GrantFiled: December 6, 2012Date of Patent: March 22, 2016Assignee: ABB RESEARCH LTDInventors: Stephan Wildermuth, Klaus Bohnert, Norbert Koch, Jan Czyzewski, Sergio Vincenzo Marchese
