Abstract: A stand is for a medical imaging system. In an embodiment, the stand includes an X-ray tube; a driver to adjust the X-ray tube in at least three spatial degrees of freedom; at least one environmental sensor to acquire at least one environmental parameter; and a controller to control an adjustment movement of the X-ray tube by generating control signals for the drive unit and to adapt the adjustment movement based on the at least one environmental parameter.

Abstract: The invention relates to a process for obtaining isobutene from an isobutene containing C4-hydrocarbon mixture (1) in a plant comprising an etherification unit (3), a first distillation unit (5), an ether cleavage unit (10) and a second distillation unit (12), the process comprising: (a) contacting the C4-hydrocarbon mixture (1) with a primary alcohol (2) and reacting the mixture with the primary alcohol in the presence of an acidic catalyst to form the corresponding alkyl tert-butyl ether in the etherification unit (3); (b) distilling the reaction mixture (4) from the etherification unit (3) in the first distillation unit (5), a C4-hydrocarbon raffinate being withdrawn as the overhead product (6), and the alkyl tert-butyl ether being withdrawn as the bottom product (7); (c) vaporizing the bottom product from the first distillation unit (5) in an evaporator (8) obtaining a vapor stream (9); (d) reacting the vapor stream (9) of step (c) in the presence of an acidic catalyst obtaining isobutene and the primary

Abstract: The invention relates to a process for obtaining isobutene from an isobutene containing C4-hydrocarbon mixture (1) in a plant comprising an etherification unit (3), a first distillation unit (5), an ether cleavage unit (8) and a second distillation unit (10), the process comprising: (a) contacting the C4-hydrocarbon mixture (1) with a primary alcohol (2) and reacting the mixture with the primary alcohol in the presence of an acidic catalyst to form the corresponding alkyl tert-butyl ether as an intermediate product and diisobutene as a by-product in the etherification unit (3); (b) distilling the reaction mixture (4) from the etherification unit (3) in the first distillation unit (5), a C4-hydrocarbon raffinate being withdrawn as the overhead product (6), the alkyl tert-butyl ether and diisobutene being withdrawn as the liquid or vaporous bottom product (7), and vaporizing the bottom product (7) if it is withdrawn as a liquid; (c) reacting the vaporous bottom product (7) in the presence of an acidic catalyst

Abstract: The invention relates to a process for starting up a plant for removing isobutene from an isobutene-containing C4-hydrocarbon mixture, the plant comprising an etherification unit containing moist acidic ion exchange resin, a first distillation unit, an ether cleavage unit, and a second distillation unit. The invention further relates to a process for shutting down the plant from a stationary operation mode.

Abstract: A control system for a medical installation, wherein the control system is configured to control a motorized movement of an installation component. The control system includes a control path and a protection path. The control path is configured to control the motorized movement. The protection path is independent of the control path and configured to monitor the control path with regard to compliance with a safety criterion for the motorized movement. The protection path includes at least one freely programmable microcontroller.

Abstract: Some embodiments are directed to a container builder (110) for building a container image for providing an individualized network service based on sensitive data (122) in a database (121). The container builder (110) retrieves the sensitive data (122) from the database (121), builds the container image (140), and provides it for deployment to a cloud service provider (111). The container image (140) comprises the sensitive data (122) and instructions that, when deployed as a container, cause the container to provide the individualized network service based on the sensitive data (122) comprised in the container image (140).

Abstract: An apparatus for examining components comprising laid fiber composite fabrics or woven fiber composite fabrics which comprise a number of thin plies with in part different alignment, comprises a measuring device for carrying out a non-destructive measurement to collect volumetric data of the component and comprising an evaluation device for evaluating the collected data of the component, wherein the evaluation by the evaluation device comprises selecting a first analysis region in the collected data of the component, determining a local coordinate system of the first analysis region, successively establishing local material properties layer-by-layer at predetermined distances in a direction perpendicular to the lateral extent of the first analysis region, detecting ply boundaries along the established material properties, and averaging the local material properties in each detected ply.

Abstract: A driver circuit for light emitting diodes (LEDs) and a driving method for LEDs. The driver circuit comprises a single stage DC-DC converter with multiple output channels, the converter comprising one set of switches on a primary side of the converter, a rectifier and voltage multiplier component at the secondary side; and a dimming control component configured to control the respective switches on the primary side of the converter for controlling an output current in the multiple output channels.
