摘要:
A method of joining at least one first metal sheet and a second metal sheet by laser welding includes at least partially stacking the at least one first metal sheet and the second metal sheet on top of one another to form an overlap region and welding together the at least one first metal sheet and the second metal sheet in the overlap region along an oscillating line. Welding along an oscillating line creates a longer weld seam in comparison to welding along a straight line, thereby increasing the strength of the weld seam.

A structure includes a first part provided in a first plane and second and third parts provided in a second plane located under the first plane. The second and third parts are welded together at a welded seam. The first part has at least one recess configured to receive a welding mechanism that forms the welded seam on the second and third parts. Another structure includes an “n” number of layers, n being at least three. Adjacent layers are in contact with one another and are connected by a welded seam. The structure also includes an outer surface. The layers between the outer surface and the respective welded seam define a recess through which a welding mechanism is configured to be passed as far as the respective layers to be welded to produce the welded seam.

A method for navigating instructional video presentations is disclosed. The method includes determining a pause mode of a video presentation, and playing the video presentation on a display device. The video presentation has one or more predetermined pause positions. The method also includes, while playing the video presentation, determining that the video presentation has reached one of the one or more pause positions. The method further includes, in accordance with a determination that the video presentation is in a first pause mode, pausing the video presentation at the one of the one or more pause positions and maintaining a display of a paused frame of the video presentation, and, in accordance with a determination that the video presentation is in a second pause mode distinct from the first pause mode, continuing to play the video presentation through the one of the one or more pause positions.

A dynamic load balancing system is described that determines the load of resources in a hosted environment dynamically by monitoring the usage of resources by each customer and determines the number of customers hosted by a server based on the actual resources used. The system receives a performance threshold that indicates when a server is too heavily loaded and monitors the resource usage by each customer. When the load of an overloaded server in the hosted environment exceeds the received performance threshold, the system selects a source customer currently hosted by the overloaded server to move to another server.

Various methods, systems, and computer program products for deferring transmission of data related to collapsing a collapsible display panel are presented. The collapsible display panel may be collapsed. State data that indicates the collapsible display panel has been collapsed may be generated. A determination that no non-state change data corresponding to the collapsible display panel needs to be transferred to a server may be made. In response, the state data may be stored at least until non-state data is to be transmitted to the server. At some time after storing the state data, non-state data that is to be transmitted to the server may be identified. In response to identifying the non-state data that is to be transmitted to the server, the state data and the non-state data may be transmitted to the server together.

A search system generates a plurality of pseudo-documents for a set of documents. Each pseudo-document includes a representation one or more documents from the set of documents that would be retrieved in response to executing a respective basis query over the set of documents. The search system generates an index of the plurality of pseudo-documents. The index provides an indication, for a plurality of respective documents from the set of documents, of the pseudo-documents that include a representation of the respective document. After generating the index, the search system receives a document-query that includes a representation of a first document; and in response to receiving the document-query, the search system identifies one or more pseudo-documents that include representations of at least one document having a predefined relationship to the first document; and generates a result that is based on the first set of one or more pseudo-documents.
摘要:
The present invention is based on the realization that the bonds between a target molecule, or a target molecule attached to a particle, and a surface, can be ruptured by mechanically oscillating the surface at increasing amplitude, leading to detachment of the target molecule or particle from the surface. The required acceleration, and hence force, will depend on a variety of factors, including the mass of the molecule or particle, the nature of the bond to the surface and the geometric shape or size of the target molecule or particle. The present invention may therefore be used to separate or to size different target molecules, or to detect their presence.
摘要:
A system and method for identifying query-related keywords in documents found in a search using latent semantic analysis. The documents are represented as a document term matrix M containing one or more document term-weight vectors d, which may be term-frequency (tf) vectors or term-frequency inverse-document-frequency (tf-idf) vectors. This matrix is subjected to a truncated singular value decomposition. The resulting transform matrix U can be used to project a query term-weight vector q into the reduced N-dimensional space, followed by its expansion back into the full vector space using the inverse of U. To perform a search, the similarity of qexpanded is measured relative to each candidate document vector in this space. Exemplary similarity functions are dot product and cosine similarity. Keywords are selected with the highest values in qexpanded that are also comprised in at least one document. Matching keywords from the query may be highlighted in the search results.

摘要:
A folding seat arrangement comprising a first carrying structure (2) having a backrest (3) and guiding elements (11) for the removable attachment in guide rails (9) to a vehicle floor, a second carrying structure (5) pivotally mounted to the first carrying structure (2) and having a seat cushion (4), and a supporting structure (6; 31), on which in a first end region guiding elements (10) are provided for the removable attachment in guide rails (9) and which in a second region is mounted a carrying structure (2; 5) in an articulated manner such that the seat arrangement in the folded setting requires the least amount of space in the lower region of the expanded luggage compartment. This is achieved in that the guiding elements (11) on the first carrying structure (2) and the supporting structure (6; 31) can be moved relative to one another to pivot the supporting structure (6; 31).
