  • Publication number: 20120159566
    Abstract: A system and method for flexible access controls access be setting access permissions at the object element or subject level. An access control framework (ACF) may be implemented to control access to business objects, business object nodes, business object queries, actions, attributes, associations, instances, or other identifiable elements. The access control configurations for a user or object may be set at the system level with static configuration settings. In an embodiment, a user may temporarily reconfigure access permissions for a subject or object for a limited session with dynamic configuration settings.

  • Publication number: 20110033275
    Abstract: The invention relates to a device for moving and positioning an object in space, having at least three actuator arms each connected to a motor/drive unit and pivotable about a motor/drive axis. The free end of each actuator arm is jointedly connected by connecting rods to a support element having at least one gripping device that can be connected to a vacuum source via a vacuum hose. The gripping device is provided with a suction opening for suctionally gripping the object. According to the invention, the vacuum hose is guided by the support element to the motor/drive axis of one of the motor/drive units, and can be connected to the vacuum source by a rotatable hose joint disposed substantially in the motor/drive axis and rotatable about the motor/drive axis.

  • Patent number: 6825048
    Abstract: The present invention relates to a method for the wet chemical preparation of materials libraries consisting of a large number of solids, the solids being deposited from reaction mixtures in microreaction chambers onto a bottom plate which simultaneously serves as the library substrate. Depending on the material selected for the library substrate, the solids can subsequently be examined non-destructively, for example, by reflecting or penetrating microarea X-ray diffraction.
