Abstract:
A system and method may be configured to analyze audio information derived from an audio signal. The system and method may track sound pitch across the audio signal. The tracking of pitch across the audio signal may take into account change in pitch by determining at individual time sample windows in the signal duration an estimated pitch and a representation of harmonic envelope at the estimated pitch. The estimated pitch and the representation of harmonic envelope may then be implemented to determine an estimated pitch for another time sample window in the signal duration with an enhanced accuracy and/or precision.

An autonomic management component is implemented in firmware comprising a set of control algorithms. Response to reading system characteristics from a plurality of sensors, the autononmic management component selects at least one control algorithm from the set and the control algorithm adjusts the parameters of the system characteristic to optimize performance according to the optimization goal specified by the customer.
Abstract:
The invention pertains to a process for preparing chlorodifluoroacetyl fluoride (CDAF) by oxidation of chlorotrifluoroethylene (CTFE) in a solvent using a continuously stirred tank reactor. It provides a process for the production of chlorodifluoroacetyl fluoride by comprises reacting a solvent solution of chlorotrifluoroethylene with oxygen in a reactor to form a product which comprises chlorodifluoroacetyl fluoride. The reacting may be conducted in a continuous or batch mode.
Abstract:
A method of coating solid supports with reactive dyes to reduce background levels is presented. Protective steps, sometimes required to prevent interaction between the chemical body and the solid phase reactant, are also described.
Abstract:
A system and method are provided for processing sound signals. The processing may include identifying individual harmonic sounds represented in sound signals, determining sound parameters of harmonic sounds, classifying harmonic sounds according to source, and/or other processing. The processing may include transforming the sound signals (or portions thereof) into a space which expresses a transform coefficient as a function of frequency and chirp rate. This may facilitate leveraging of the fact that the individual harmonics of a single harmonic sound may have a common pitch velocity (which is related to the chirp rate) across all of its harmonics in order to distinguish an the harmonic sound from other sounds (harmonic and/or non-harmonic) and/or noise.
Abstract:
A system and method may be provided to segment and/or classify an audio signal from transformed audio information. Transformed audio information representing a sound may be obtained. The transformed audio information may specify magnitude of a coefficient related to energy amplitude as a function of frequency for the audio signal and time. Features associated with the audio signal may be obtained from the transformed audio information. Individual ones of the features may be associated with a feature score relative to a predetermined speaker model. An aggregate score may be obtained based on the feature scores according to a weighting scheme. The weighting scheme may be associated with a noise and/or SNR estimation. The aggregate score may be used for segmentation to identify portions of the audio signal containing speech of one or more different speakers. For classification, the aggregate score may be used to determine a likely speaker model to identify a source of the sound in the audio signal.

The connection device (50) may be authenticated prior to enabling a stacking feature. Authentication of a connection device may be used to ensure the quality and performance of the connection device (50) and the data modules.
Abstract:
A method for constructing a metal wire with embedded filaments or cavities therein for biomedical applications. The method includes first drilling nonconcentric apertures in a symmetrical pattern in a metal rod and then embedding filaments in the apertures. The metal rod is then drawn and thermally-treated to form a metal wire with embedded filaments therein. The filaments may advantageously provide fatigue resistance, radiopacity, and electrical conductance to the metal wire. The method optionally provides an additional step for withdrawing or removing the filaments using various methods to create cavities for cavity access within the metal wire. The metal wire may be finished to provide access to the cavities or filaments embedded therein. The cavities may then be filled with a therapeutic drug for elution inside the human body or used for passage of body fluids. An optional biocompatible coating may be disposed around the metal wire to prevent escape of the therapeutic drug before insertion into the human body. The cavities may also be filled with different materials as compared to the original filaments.
