Patent number: 11806185Abstract: A computer-implemented method is for determining at least one main acquisition parameter determining a dose of x-rays to be emitted from an x-ray emitter during image acquisition using an x-ray emitter and an x-ray detector. A first image data of a first preparatory image is evaluated to determine if a repeat condition is fulfilled and/or to determine the main acquisition parameter and/or at least one second preparatory acquisition parameter. The first preparatory image is acquired by the x-ray detector using at least one first preparatory acquisition parameter to control the x-ray emitter. In all cases or when the repeat condition is fulfilled, the main acquisition parameter is determined depending on second image data of a second preparatory image, acquired by the x-ray detector after the first preparatory image while at least one second preparatory acquisition parameter is used to control the x-ray emitter.Type: GrantFiled: January 7, 2021Date of Patent: November 7, 2023Assignee: Siemens Healthcare GmbHInventors: Andre Gebhardt, Sebastian Glawion, Thilo Hannemann, Carsten Illenseer, Daniel Lerch, Thomas Pfeiffer, Stefan Schaffert, Peter Scheuering, Bastian Schmidt, Thomas Weber, Wei He, Sven-Martin Sutter, Zhi Ming Yang

Patent number: 9464456Abstract: A system for protecting stored goods in a storage room, having one or more storage constructions formed by one or more pesticide treated nets (30, 31), capable of enclosing the stored goods, where the storage construction further includes a support frame, means for suspending the support frame, means for opening and closing at least one section of the storage construction while the support frame is in a suspended state, and means for avoiding an overall structural collapse if a net gets entangled. The system is particularly useful for the storage of tobacco, coffee, dried fruits, cocoa, nuts, tea, cereals and spices.Type: GrantFiled: June 26, 2012Date of Patent: October 11, 2016Assignee: BASF SEInventors: Jürgen Weiser, Daniel Bihlmeyer, Claus Kaiser, Michael Faber, Agustin Izquierdo, Stefan Schaffert, Nils Stello, Torsten Gröschl, Udo Schmidt

Publication number: 20080223360Abstract: The invention relates to a method for producing modified lignocellulosic materials. Said method consists of the following steps a) the lignocellulosic material is impregnated with an aqueous composition which contains i) at least one cross-linkable nitrogen compound and ii) at least one substance which catalyses the cross-linking, b) the impregnated lignocellulosic materials are treated at higher temperatures in order to remove the water and to cross-link the cross-linkable nitrogen compound. In step b) the impregnated lignocellulosic material is treated with overheated steam. The invention also relates to lignocellulosic materials which are obtained according to said method.Type: ApplicationFiled: October 2, 2006Publication date: September 18, 2008Applicant: BASF SEInventors: Arend Jouke Kingma, Franz Weingart, Stefan Schaffert, Holger Militz, Andreas Krause, Falko Wepner
