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.

A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that “virtualizes” a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server.

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 cladding (cover) element (32) includes a reception unit which is integrated therein. The reception unit contains a receiving coil (10) for the contactless transfer of electric energy and a plurality of flux-conducting elements (15a, 15b; 16a, 16b) that are associated with the receiving coil (10) for concentrating the field strength. The cover element (32) is made of a fiber-reinforced plastic. The flux-conducting elements (15a, 15b; 16a, 16b) and the receiving coil (10) are arranged in a base body (18) that is used to position the elements and coil and are embedded with the base body (18) in the cladding element (32). A process is also provided for producing the cladding element (32).

The invention relates to a method and a device for preventing fast changes of the atmospheric pressure in an enclosed room (1) induced by an external environment. According to the invention, the internal pressure in the room (1) is monitored by a sensor (3). Fast changes of the internal pressure are at least partially compensated for by the targeted supply or removal of air. The supply and removal of air preferably occurs with overpressure and underpressure containers (5, 6).

A magnetic levitation vehicle has at least one magnetic arrangement (27). The magnetic arrangement (27) contains a plurality of magnetic poles (27a . . . 27n) which are arranged one behind the other in the direction of travel and comprise windings (33) associated therewith. The magnetic levitation vehicle is also provided with a circuit for supplying the windings (33) with a direct current, said circuit containing switches for selectively switching the magnetic arrangement between a guiding function and/or a braking function.

Disclosed is a switch arrangement for magnetically levitated railways, comprising a support (1), which is bendable transversally to the direction of travel and is provided with track or component fittings, a rail arranged transversally to the direction of travel, a rack (23) arranged transversally to the direction of travel and a supporting frame (15) for receiving said support (1). The supporting frame is supported on the rail by a running wheel (16) and comprises a drive mechanism (18) with a toothed wheel (20) that engages in the rack (23) as well as a motor for the propulsion thereof. According to the invention, the support (1), the supporting frame (15) and the drive mechanism (18) form, as an entity, a firmly connected assembly which is arranged in such a manner that it can be displaced in the direction of travel and relative to the rail (17) and the rack (23).
摘要:
A method and an apparatus allows complete and efficient verification of cross-architecture ISA emulation. A random verification framework runs concurrently on two different computer architectures. The framework operates without regard to existing native applications and relies instead on binary instructions in a native ISA. The framework determines emulation errors at a machine instruction level. A random code generator generates one or more sequences of native machine instructions and corresponding initial machine states in a pseudo-random fashion. The native instructions are generated from an entire set of the native ISA. The instructions and the state information are provided to initialize a native computer architecture. The same instructions and state information are provided using standard machine-to-machine languages, such as TCP/IP, for example, to a target computer architecture. A binary emulator then translates the native instructions so that the instructions may be executed on the target computer. Alternatively, the binary emulator may be embodied as a software routine operating on a simulator, which in turn operates on the native computer architecture. The final states of the native and the target computer architectures are gathered, and a verification engine compares the results. Any differences may indicate an emulation error or failure. The random verification framework may be run continuously to test emulation of the complete set of instructions from the native ISA after the testing continues for an infinite length of time.

摘要:
The guideway support comprises at least one gliding surface (14, 19, 34) for magnetic levitation vehicles (4), which have at least one skid (8) designated for placement on the gliding surface (14, 19, 34), wherein the gliding surface (14, 19, 34) is provided with a low-friction, multi-layered coating having at least one ceramic layer (15, 22, 35, 36) arranged on the gliding surface (14, 19, 34). The guideway support is characterized in that at least one non-ceramic layer (17, 23, 37), produced in a thermal spraying process, is arranged on the ceramic layer (15, 22, 35, 36).
