Abstract
Abstract An initialization beacon for initializing a stationary vehicle, particularly for assisting the driving, operation, and maintenance of the stationary vehicle, comprises superposing cross-over structures Si, whereby each cross-over structure is made from a first electrical cable Ci1 and a second electrical cable Ci2. The first electrical cable Ci1, which mutually parallels with the second electrical cable over most of its length, crosses over the second electrical cable Ci2 to form a succession of magnetic nodes N. The magnetic nodes of each of the superposed cross-over structure form magnetic nodes Nij in the superposed cross-over structures. The magnetic nodes NiJ are staggered in a non-overlapping fashion according to a space period in each of the superposed cross-over structures. Pairs Pmn of the superposed cross-over structure Si can be successively powered at a clock frequency FH and a data frequency FD.
