An audio signal decorrelator for deriving an output audio signal from an input audio signal has a frequency analyzer for extracting from the input audio signal a first partial signal descriptive of an audio content in a first audio frequency range and a second partial signal descriptive of an audio content in a second audio frequency range having higher frequencies compared to the second audio frequency range. A partial signal modifier for modifies the first and second partial signals, to obtain first and second processed partial signals, so that a modulation amplitude of a time variant phase shift or time variant delay applied to the first partial signal is higher than that applied to the second partial signal, or for modifying only the first partial signal. A signal combiner combines the first and second processed partial signals, or combines the first processed partial signal and the second partial signal, to obtain an output audio signal.

Embodiments of the invention generally relate to a method for etching in a processing platform (e.g. a cluster tool) wherein robust pre-etch and post-etch data may be obtained in-situ. The method includes the steps of obtaining pre-etched critical dimension (CD) measurements of a feature on a substrate, etching the feature; treating the etched substrate to reduce and/or remove sidewall polymers deposited on the feature during etching, and obtaining post-etched CD measurements. The CD measurements may be utilized to adjust the etch process to improved the accuracy and repeatability of device fabrication.

This invention provides a process for producing an epoxy resin composition having core/shell rubber particles (rubber-like polymer particles) dispersed in an epoxy resin, wherein an epoxy resin composition excellent in the dispersed state of rubber-like polymer particles in an epoxy resin with a reduced amount of contaminants is produced easily and efficiently. The epoxy resin composition having rubber-like polymer particles dispersed well in an epoxy resin with less contaminant is obtained by bringing an aqueous latex of rubber-like polymer particles (B) into contact with an organic medium (C) showing partial solubility in water, then bringing an organic medium (D) having lower partial solubility in water than that of the organic medium (C) into contact therewith to separate water substantially, to remove the rubber-like polymer particles as a dispersion (F) having the polymer particles dispersed in the organic medium, and mixing it with an epoxy resin (A), followed by distilling volatile components away.

A system and method for repairing an area of defective tissue reduces the removal of healthy tissue at the margins of the defect. During excision of diseased or damaged tissue, the system tracks the movement and function of a tissue resection tool within a monitored surgical space. This movement is continuously recorded to create a three-dimensional set of data points representative of the excised volume of tissue. This data set is then communicated to a custom implant forming device which creates a custom implant sized to fit the void created by the excision. The system and method of the present disclosure allows a surgeon to exercise intraoperative control over the specific shape, volume and geometry of the excised area. Moreover, the surgeon may utilize a “freehand” resection method to excise only that tissue deemed to be diseased and/or damaged, because the custom-formed implant will accommodate an irregularly-shaped resection volume.

An insert for a siamese-type internal combustion engine that separates a water jacket surrounding the cylinders into an upper portion and a lower portion. Below a predetermined engine speed coolant flows primarily in the upper water jacket portion so as to provide enhanced cooling at the upper portions of the cylinders. Above a predetermined engine speed coolant is introduced into the lower water jacket portion from the upper water jacket portion so as to provide improved cooling of the lower cylinder portions, without compromising cooling of the upper cylinder portions or the conjoined cylinder wall portions. The water jacket insert enhances coolant flow velocity at the siamesed or conjoined portions of the cylinder walls, and directs incoming initially coolant over the exhaust-side of the cylinders. Use of the insert reduces circumferential and axial intra-cylinder temperature deviations as well as inter-cylinder temperature deviations.
