An inductive power supply system for providing power to one or more inductively powered devices. The apparatus also receives from the external apparatus a response signal indicating whether the external apparatus will accept transmission of the target image data in accordance with the data amount information, the information of priority order, and a free storage capacity to store the target image data in the external apparatus. The residual frequency error is small after correcting for the frequency error and allows the receiving station to perform coherent accumulationintegration over a longer time interval to detect for a packet transmission. By means of a on-photolithographic mask having mask sections aligned with the trench capacitors, trench-insulator structures are provided in each case between a sidewall gate section of a word line and the adjoining trench capacitor, said trench-insulator structures decoupling the respective trench capacitor from the traversing word line. The method is directed to ensure that for a required level of protection, derived from a maximum risk level allowed, no segments in the protection path, when taken together with any segment of the main path, presents a risk higher than the maximum risk level allowed.
