摘要:
A method and appertaining system operate on digital images that are grouped into a plurality of image groups. Each digital image is subjected to a two-dimensional intra-image wavelet transformation. Further, the digital images of each image group are subjected to an inter-image wavelet transformation. The digital images are encoding using the intra-image wavelet transformation coefficients and the inter-image wavelet transformation coefficients are formed.

The invention relates to a magnetic levitation vehicle (11) and to a method for lifting said magnetic levitation vehicle (11) and to lowering said magnetic levitation vehicle onto a roadway. According to the invention, the carrier magnetic units (38) of the magnetic levitation vehicle (11) are not all activated or deactivated at the same time but at different times in order to keep the current energy requirement from an external energy supply or main power supply to a minimum.

A method for operation of a magnetic levitation railway which contains vehicles with a plurality of supporting magnets (20a . . . 20j) and supporting runners (26) associated with them. In the event of a malfunction, the braking of the vehicle with the drive and braking systems switched off is brought about or assisted until a preselected destination stopping point is reached solely in that, even before the destination stopping point is reached, at least one of the supporting magnets (for example 20f, 20g) is switched off, and the magnetic levitation vehicle is placed on the track path (3) by means of the associated supporting runner (26), and is brought to rest at the destination stopping point by making use of the friction forces that occur as a result. A magnetic levitation vehicle is provided and operated in this way.

The invention relates to a magnetic bearing and to a method for operation thereof. The magnetic bearing contains a ferromagnetic, movably mounted bearing element (1) and at least two magnetic devices (3o, 3u) arranged on opposing sides of the bearing element (1) and equipped with windings (6), wherein during operation of the magnetic bearing, electric currents are conducted through the windings (6) and these currents are regulated such that in an equilibrium state between the bearing element (1) and the two magnetic devices (3o, 3u), bearing gaps (10o, 10u) of predetermined size (So, Su) form. According to the invention, the temperatures produced in the magnetic devices (3o, 3u) during operation are measured and the regulation of the currents takes place such that in the equilibrium state, regardless of the load situation, the same temperatures appear in the magnetic devices (3o, 3u) or in the windings (6) thereof (FIG. 1).

摘要:
Disclosed is a linear synchronous motor comprising an elongate stator extending in a longitudinal direction and having a plurality of coil windings, and a runner having a multiplicity of successive magnets disposed along the length thereof the longitudinal direction. The elongate stator has a plurality of elongate-stator segments arranged successively in the longitudinal direction, with each elongate-stator segment separated from the next successive elongate-stator segment by a gap. A total section length of one elongate-stator segment and an adjacent gap is a constant value over a plurality of successive elongate-stator segments, wherein a runner length measured in the longitudinal direction across all magnets successively disposed on the runner, is an integer multiple of the total section length.
