In an aircraft galley, a power network distributes power from a source to electrical consuming devices (oven, water boiler, coffee machine, trash compactor, etc.). A control unit is connected to and can individually address each of the devices via a databus. The control unit compares the actual existing power consumption to a prescribed maximum value. If the actual consumption reaches the maximum value, the control unit calls up a power reduction procedure from a catalog in a database, and provides corresponding control signals to one or more of the devices to reduce the power consumption below the maximum value. The individual devices receive power in a time-sharing, power-sharing, or time-staggered manner. An intelligent distribution of available power resources avoids power overloads, and allows optimal utilization of all galley devices without limiting the normal catering process.

In a method and magnetic resonance (MR) apparatus for MR image reconstruction, an image reconstruction algorithm is used that operates on one calibration matrix that is formed by reorganizing a number of individual, undersampled k-space data sets respectively acquired by multiple reception coils in a parallel MR data acquisition from a subject exhibiting motion. The motion causes the k-space data sets to exhibit errors. In order to use the calibration matrix in the reconstruction algorithm, it is subjected to an iterative rank reduction procedure in which, in each iteration, a residual is calculated for each data point that represents how poorly, due to motion-induced corruptions, that data point satisfies the low rank constraint, and non-satisfying data points are removed from the data point for the next iteration. The resulting low rank matrix at the end of the iterations is then used to produce images with fewer motion-induced errors.
