Abstract: A method for positioning a mobile patient couch relative to a stationary medical device, comprises: capturing, by an optical sensor, a first optical marker in an image; providing the image to a controller; determining, by the controller, a position and/or orientation of the mobile patient couch relative to the stationary medical device based on the image of the first optical marker and/or of the first optical marker comprised by the image; and positioning the mobile patient couch by controlling the drive unit and/or the steering unit based on the position and/or orientation of the mobile patient couch relative to the stationary medical device.

Abstract: In a method for operation of a docking arrangement, position information is determined that describes a position of the patient table, including detecting, sensor data corresponding to: the position of the patient table relative to the docking arrangement, and/or to an environment feature describing a movement trajectory to the docking arrangement. The method may further include performing, in response to a switchover condition indicative of a handover situation and a purely manual operation of the patient table by an operator, a switch into an assistance operating mode of the docking arrangement. In the assistance operating mode, at least one guidance measure may be determined for the patient table and a functional component of the patient table may be controlled to assist the operator.

Abstract: A method for determining items of object information in at least one of a medical examination or treatment arrangement with at least one object is provided. The at least one object is captured via at least one camera and an item of object information includes at least one of identification information or positional information relating to the at least one object. The item of object information is determined via a control device by evaluating camera data from at least one camera image obtained by the at least one camera, and the at least one object is equipped with a tracking device. The method comprises: determining, via the tracking device, an item of pose information describing at least one of a position or an orientation of the at least one object; and using the item of pose information to determine the item of object information.

Abstract: A mobile medical device is driven by a chassis. The movement is brought about, or at least supported by, at least one drive. A direction influencing device varies the direction of movement. Both the drive and the direction influencing device may be activated by a control device. End stations and paths leading to the end stations, as well as a current position of the device, are known to the control device. The control device accepts a drive request from an operator and establishes an at least approximate desired direction of the movement. The control device activates the drive while accepting the drive request and activates the direction influencing device to drive the device on one of the paths while accepting the drive request and while the current position of the device is approximately on the path. Furthermore, the control device continuously updates the position of the device during movement.

Abstract: A computer implemented method of assembling a state space model system for controlling a movement of a component of a mechatronic system comprises specifying a set of input parameters and a set of output parameters for an initial set of state space models, which is determined by mapping multiple sets of values of the specified set of input parameters to multiple associated sets of values of the specified set of output parameters. The determined initial set of state space models is optimized by identifying approximately linear regions, which comprise regions in a parameter space of the initial set of state space models, and selecting one state space model per approximately linear region. The parameter space comprises the input parameters and the output parameters. The selected state space models are assembled for obtaining the state space model system.
