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.
Abstract:
Techniques for media segmentation are disclosed. A number of measures used to generate similarity values are compared. Two different approaches to calculate feature vectors based on pairwise frame similarity in combination with different kernel functions are disclosed. A supervised classification method is used with the feature vectors to assess segment boundaries.
Abstract:
Music videos are automatically produced from source audio and video signals. The music video contains edited portions of the video signal synchronized with the audio signal. An embodiment detects transition points in the audio signal and the video signal. The transition points are used to align in time the video and audio signals. The video signal is edited according to its alignment with the audio signal. The resulting edited video signal is merged with the audio signal to form a music video.
Abstract:
Systems and methods in accordance with the present invention can be applied to generate a personal media library of media segments from a media stream. A method in accordance with one embodiment can comprise receiving the media stream, identifying one or more novelty points within the media stream and creating a plurality of media segments based on said one or more novelty points. The method can further be applied to compile a playlist or substitute media stream organizing such stream as desired, eliminating redundant media clips and discarding advertisements.
Abstract:
A method for forming letters using a template by grouping letters based on similarities in the direction of muscle movement which takes advantage of the similar hand movements used with-in particular groups of letters. The learning of these letters is organized so that after one letter is mastered, another letter is learned based on the similarities of hand movements used in printing a learned letter and the next letter being taught. The handwriting method facilitates learning how to read and write in new languages.
Abstract:
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.
Abstract:
Automatic system upgrades are provided to a customer by a service provider based on the customer's preferences and parameters. The automatic upgrade system may manage customer preferences for the scheduling of automatic upgrades according to parameters such as date, time, and capacity. The upgrade system may automatically provide system upgrades to customer systems according to the customer preferences taking into account system health and status, customer parameters, and customer priority as determined by the service provider.
