Patent number: 10088443Abstract: Carriers for biomaterials, for polyelectrolyte materials, for electrically polarizable atoms, ions, molecules are provided wherein the material of the carriers is compatible with materials that are used in microelectronics. The arrangement of the biomaterials or biomolecules and optionally of biomolecules, biomaterials, biological functional units or cells adsorbed thereon can be affected with the carrier in a specific manner. Complex molecular machines can be built and tested by the carriers.Type: GrantFiled: August 31, 2012Date of Patent: October 2, 2018Assignees: HELMHOLTZ-ZENTRUM DRESDEN-ROSSENDORF E.V., LEIBNIZ-INSTITUT FÜR POLYMERFORSCHUNG DRESDEN E.V.Inventors: Heidemarie Schmidt, Christine Baumgart, Ilona Skorupa, Manfred Helm, Oliver G. Schmidt, Martin Müller

Patent number: 7926871Abstract: The invention relates to a headrest (10) for a vehicle seat, in particular for a backrest for a motor vehicle seat, said headrest essentially comprising a headrest frame or headrest casing (14) and a foam base body (356) that surrounds the headrest frame or casing (14). In the event of a rear impact on the motor vehicle, the headrest remains fixed in relation to the backrest (conventional headrest) or at least part of the headrest is immediately displaced towards the vehicle occupant (active headrest). According to the invention, the head of a vehicle occupant can be brought into contact with the headrest (10) at least at two different heights (k1z, k2z), (two-point contact), to reduce or neutralize a torque (My) about a y-axis (y-y) in the vicinity of the vertebral column and to prevent accident-related injuries to the seat occupant, in particular to prevent cervical spine syndrome or a whiplash injury in the event of a front and/or rear impact.Type: GrantFiled: May 24, 2006Date of Patent: April 19, 2011Assignee: Volkswagen AktiengesellschaftInventors: Armin Meixner, Manfred Helm, Andreas Hoffmeister, -Ing Dirk Pförtner, Peter Schmuda von Trzebiatowski, Horst Rademacher, Ralf Lühring

Patent number: 7848376Abstract: A quantum cascade laser structure in accordance with the invention comprises a number of cascades (100), each of which comprises a number of alternately arranged quantum wells (110a to 110j) and barrier layers (105 to 105j). The material of at least one quantum well (110a to 110j) as well as the material of at least one barrier layer (105 to 105j) is under mechanical strain, with the respective strain being either a tensile strain or a compression strain. The quantum wells (110a to 110j) and barrier layers (105 to 105j) are engineered in the quantum cascade laser structure in accordance with the invention so that existing strains are largely compensated within a cascade (100). In the quantum cascade laser structure in accordance with the invention, each material of the quantum wells (110a to 110j) has only one constituent material and the material of at least one barrier layer (105d, 105e, 105f) has at least two constituent materials (111a, 111b, 112a, 112b, 113a, 113b).Type: GrantFiled: July 10, 2008Date of Patent: December 7, 2010Assignees: Humboldt-Universtaet Zu Berlin, Forschungszentrum Rossendorf e.V.Inventors: William Ted Masselink, Sebastian Dressler, Mykhaylo Petrovych Semtsiv, Nikolai Georgiev, Manfred Helm, Thomas Dekorsy, Mathias Ziegler
