Abstract: A device for preparing a supply voltage contains an input for receiving the supply voltage and a voltage converter for transforming an input voltage present at an input of the voltage converter into an output voltage to be output at an output of the voltage converter. A voltage limiter is provided for limiting a backwards voltage dropping from the output to the input of the voltage converter. This enables a high level of safety of the voltage converter and a high reliability of the device to be guaranteed, especially against a short circuit condition at the output of the voltage converter.

Abstract: A method and system for specifying, in a schema mapping framework, a mapping between a source schema and a target schema. The source and target schemas are schemas included in respective groups of registered, heterogeneous schemas. The source and target schemas may be of different types. Serialized versions of the source and target schemas include source objects and target objects, respectively. A mapping model is serialized into mapping objects that include logical references representing the source objects and logical references representing the target objects. The logical references are resolved to the source objects and target objects, thereby storing pointers to the source objects and to the target objects. After resolving the logical references, the mapping model includes the logical references and the pointers to the source and target objects.

Abstract: A method and system for generating a query implementing a schema mapping. A mapping M is provided from a schema S to a schema T, where M relates S to T, and M includes a plurality of constraints. Schemas S and T each include one or more elements, and T includes at least one set type element. Mapping M is expressed in terms of at least one nested tuple-generating dependency. A query Q is generated where Q is capable of applying M to an input instance I to result in an output instance J, where I conforms to S, J conforms to T, and I and J satisfy the plurality of constraints. Instance J is in partitioned normal form (i.e., satisfies minimal union semantics) and includes no duplicate element instances.

Abstract: A circuit configuration controls an inductive consumer, especially protecting the consumer from being accidentally turned on. The circuit configuration contains a free-wheeling circuit for reducing energy stored in the consumer. In order to prevent the consumer from being accidentally turned on when a grounding wire between an energy store and the circuit configuration is interrupted, the free-wheeling circuit is interrupted after a given period of time once the consumer has been turned off such that the consumer is prevented from being charged by a current flowing from the positive pole of the energy store via the electronics of the circuit configuration and the free-wheeling circuit.

Abstract: Techniques are provided for viewing mappings between objects. A main view is displayed, wherein the main view shows one or more source objects, one or more target objects, and zero or more mappings between the one or more source objects and the one or more target objects. Input selecting a type of view to be displayed in the main view is received, wherein each type of view provides a different amount of detail regarding the mappings. In response to receiving the input, the selected type of view is created, and the created view is displayed. Additionally, techniques are provided for viewing objects. One or more objects along with mappings between the one or more objects are displayed. View filters are provided that may be applied to the one or more objects, wherein the view filters enable hiding at least one of mapped or unmapped objects. Moreover, techniques are provided for viewing nodes. A structure is displayed that includes one or more nodes.

Abstract: Various embodiments of a method, system and article of manufacture to discover relationships among a first set of elements and a second set of elements are provided. At least one metric algorithm is identified based on a metric selection parameter. A raw result is determined based on the at least one metric algorithm, a first specified structural description of the first set of elements and a second specified structural description of the second set of elements. The raw result comprises a plurality of relationship measurements and the raw result is ordered. In some embodiments, a balanced result is produced based on the raw result and a matching strategy algorithm. In other embodiments, the matching strategy algorithm is identified based on a matching strategy selection parameter.

A voltage limiter is provided for limiting a backwards voltage dropping from the output to the input of the voltage transformer.

Abstract: The semantic integration problem for merging multiple databases of very large size, the merge/purge problem, can be solved by multiple runs of the sorted neighborhood method or the clustering method with small windows followed by the computation of the transitive closure over the results of each run. The sorted neighborhood method works well under this scheme but is computationally expensive due to the sorting phase. An alternative method based on data clustering that reduces the complexity to linear time making multiple runs followed by transitive closure feasible and efficient.
