Abstract: A method for monitoring a recumbent patient to obtain information on a body position of the patient comprises the steps of emitting electromagnetic waves by a sender (11) arranged in a distance from the patient, receiving electromagnetic waves reflected by the patient by a receiver (12, 13, 14) arranged in a distance from the patient, determining a movement activity level from an amplitude and/or phase of the received electromagnetic waves, classifying the activity level into at least one high activity level class and into at least one low activity level class and analyzing the amplitude and/or phase of the received electromagnetic waves relating to an activity level classified in the at least one low activity level class to obtain the information on the body position of the patient.

Abstract: In a method for analyzing the distribution of objects in a free queue, proceeding from position information, firstly a monitoring region comprising the free queue is subdivided into a plurality of positions. Proceeding from the position information, objects assigned to the free queue are identified. Said objects are subsequently tracked. At least for a portion of the identified objects, a current waiting time in the free queue is tracked. At least for a portion of the positions of the monitoring region, the current waiting time of one or a plurality of the identified objects situated at the corresponding positions is assigned. Furthermore, the positions with assigned waiting times are classified into a plurality of classes, wherein each of the classes corresponds to a continuous waiting time range.

Abstract: In a method for determining the spatial extent of a free queue, proceeding from position information, firstly a monitoring region comprising the free queue is subdivided into a plurality of positions. Proceeding from the position information, objects assigned to the free queue are identified and tracked. A current position of at least a portion of the tracked objects is periodically stored. An average speed of at least a portion of the objects is determined, wherein the average speed of an object is determined on the basis of a plurality of the stored positions of the respective object. Finally, a first map is created, which records, in relation to the positions in the monitoring region, an occurrence density of objects at the corresponding positions, Objects having an average speed outside a predefined range are not taken into account when creating the first map.

Abstract: A method for processing image data representing a three-dimensional volume, the data comprising image values for a three-dimensional grid of voxels, comprising: starting from a given voxel building up a vector path along a first dimension of the three dimensional volume, connecting a number of voxels of two-dimensional slices of the grid adjacent in the first dimension, the connected voxels representing a spatial neighborhood of the given voxel, including structurally related voxels of the three-dimensional grid; averaging the image values of the voxels of the vector path to obtain a first averaged value, assigned to the given voxel position; repeating the aforementioned steps for a number of voxels; repeating the aforementioned steps on the first averaged values, employing vector paths along a second dimension being different from the first dimension, obtaining second averaged values; and on the second averaged values repeating the aforementioned steps, employing vector paths along a third dimension being di
