Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
Environmental information combined with satellite driven observations and ground observations to create a predictor for wildfire at high spatial resolution. Temperature and precipitation are bias corrected using modeling and processing techniques driven from reanalysis datasets. Such techniques can be used to provide projections of future climate risk data at high temporal cadence over individual addresses or over large regions using spatial aggregation using polygon processing techniques.
Abstract:
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.
Abstract:
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).
Abstract:
In accordance with the present invention there is provided a bi-stable oscillator circuit for detecting a load imparted to a surface. The bi-stable oscillator comprises an electrical amplifier, at least one resonator comprising an electrical transducer having a resonant frequency, a surface of the resonator forming the surface on which the load is to be detected and an impedance network having a resonant frequency. The resonator is arranged to be exposed to an environment under test, and the resonator and the impedance network are connected in parallel with the electrical amplifier such that when a load imparted to the surface exceeds a pre-determined threshold value the oscillator circuit oscillates at the resonant frequency of the impedance network and when a load imparted to the surface is less than the threshold value the oscillator circuit oscillates at the resonant frequency of the resonator, switching of the circuit oscillation frequency being indicative of the load crossing the predetermined threshold value.
Abstract:
Systems and methods for automating digital file classification are described. The systems and methods include generating a plurality of classifiers from a plurality of first features of a plurality of first digital files, each of the plurality of first digital files having one or more associated annotations. A plurality of second features extracted from a plurality of second digital files is sorted according to the plurality of classifiers. A distance vector is determined between the second features and respective first features for the corresponding ones of the classifiers and the determined distances are ranked. A subset of matched files is selected based on the ranking. The subset of matched files correspond to respective one or more associated annotations. One or more annotations associated with the subset of matched files are associated to subsequently received digital files using the corresponding ones of the classifiers.
Abstract:
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.
Abstract:
Embodiments of the present invention introduce a user navigation interface that allows a user to monitor/navigate video streams captured from multiple cameras. It integrates video streams from multiple cameras with the semantic layout into a 3-D immersive environment and renders the video streams in multiple displays on a user navigation interface. It conveys the spatial distribution of the cameras as well as their fields of view and allows a user to navigate freely or switch among preset views. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
