  • Publication number: 20180262832
    Abstract: A sound signal processing apparatus including a plurality of microphones, where each microphone is configured to receive the sound signal from the target source, a processor configured to estimate a first power measure on the basis of the sound signal from the target source received by a first microphone of the microphones and a second power measure on the basis of the sound signal from the target source received by at least a second microphone of the microphones, which is located more distant from the target source than the first microphone, and the processor is further configured to determine a gain factor on the basis of a ratio between the second power measure and the first power measure, and an amplifier configured to apply the gain factor to the sound signal from the target source received by the first microphone.

  • Patent number: 9764508
    Abstract: The invention relates to a method for producing hollow bodies from thermoplastic material and to an apparatus for carrying out the method. The method comprises the molding of at least two sheet-like preforms in web form of thermoplastic material into two complementary shells in a multi-part tool, which in a closed position forms a mold impression, and the joining together of the shells to form an essentially closed hollow body, the preforms being brought between the parts of the tool in an opened receiving position of the parts of the tool and the preforms being placed into the part-cavities by applying differential pressure and being at least partially molded in them into shells. The shells are joined together to form an essentially closed hollow body by closing the tool to form a closed mold impression. The method is distinguished by the fact that the preforms are molded in the part-cavities while the parts of the tool are located in the opened receiving position.

  • Publication number: 20130228573
    Abstract: The invention relates to a method for the production of hollow bodies from thermoplastic plastic. The method comprises the extrusion of at least two sheet-like preforms consisting of thermoplastic plastic, the introduction of the preforms into a preferably multipart molding die with a molding cavity which at least partially defines the contour of the hollow body to be manufactured, and the shaping of the preforms inside the die, using a vacuum and/or gas pressure in the first heat of the material. The method is distinguished in that at least two preforms to be shaped into a hollow body and to be connected are extruded successively, that is to say sequentially, in time and are shaped simultaneously.

  • Patent number: 8315478
    Abstract: A coordinate system converter efficiently converts coordinates of one coordinate system to a different coordinate system. A base system library module provides a common platform where different algorithms based on different coordinate systems can “shake hands” or be integrated into an overall conversion process in a manner that is transparent to each other. The number of supported coordinate systems can be dynamically extended without changing software to support different tools.

  • Publication number: 20090106002
    Abstract: A process analysis and simulation framework is configured with several adaptable libraries that provide a user with the ability to select plug-in modules that are applicable to a particular process simulation. The user may add or remove modules to configure the framework with specific functionality and parameters according to the needs of a particular process simulation. The plug-in modules may execute individually or dependencies may be established between multiple plug-in modules. A simulation engine executes the process simulation to determine an optimized solution for the data. The data used in the execution of the process simulation may be manually input, provided by the plug-in modules, or retrieved from external sources. The output of the process simulation is displayed to the user and stored in a file or a database for future use. Thus, the stored output may be used in a subsequent process simulation to progressively refine an application.

  • Patent number: 7260483
    Abstract: An improved method and system of identifying individual aerosol particles in real time. Sample aerosol particles are collimated, tracked, and screened to determine which ones qualify for mass spectrometric analysis based on predetermined qualification or selection criteria. Screening techniques include one or more of determining particle size, shape, symmetry, and fluorescence. Only qualifying particles passing all screening criteria are subject to desorption/ionization and single particle mass spectrometry to produce corresponding test spectra, which is used to determine the identities of each of the qualifying aerosol particles by comparing the test spectra against predetermined spectra for known particle types. In this manner, activation cycling of a particle ablation laser of a single particle mass spectrometer is reduced.

  • Publication number: 20050142239
    Abstract: A thermoforming tool for producing cup-shaped molded parts from a heated film of plastic includes an upper tool and a lower tool, which are movable in relation to each other for clamping the film of plastic therebetween. At least one mold cavity for forming a molded part from the film of plastic is formed in the lower tool and at least one prestretching structure movable into a corresponding mold cavity is arranged in the upper tool inside a hold-down device. The prestretching structure includes at least two prestretching levers pivotable about an associated pivot axis, which lies in a plane running perpendicularly to the direction of movement of the prestretching structure. Each of the prestretching levers has a stretching arm extending downward, and a stop arm extending upward.
