US07884276B2 Music transcription
Methods, systems, and devices are described for automatically converting audio input signal data into musical score representation data. Embodiments of the invention identify a change in frequency information from the audio signal that exceeds a first threshold value; identify a change in amplitude information from the audio signal that exceeds a second threshold value; and generate a note onset event, each note onset event representing a time location in the audio signal of at least one of an identified change in the frequency information that exceeds the first threshold value or an identified change in the amplitude information that exceeds the second threshold value. The generation of note onset events and other information from the audio input signal may be used to extract note pitch, note value, tempo, meter, key, instrumentation, and other score representation information.
US07884273B2 Method and use of warm-up instructional video for wind instrument
An instructional system and method for students of wind instrument that include audio/video depictions for viewing by users of the system and method an instructor performing steps on a wind instrument, an animated breathing bar presented at least during a time period over which a user is to attempt to replicate the steps demonstrated by the instructor, such breathing bar to visually command a user to alternatively inhale or exhale (while producing tones on his or her wind instrument), and visual indicia instructing in textual form the step or steps to be carried out by a user. A system can include one or many steps being demonstrated and prompted for recreation by a user, as well as additional presentations, such as metronomes, interactive tuners, and the like.
US07884261B2 Nucleotide sequences and corresponding polypeptides conferring modulated plant growth rate and biomass in plants
The present invention relates to isolated nucleic acid molecules and their corresponding encoded polypeptides able confer the trait of modulated plant size, vegetative growth, organ number, plant architecture, growth rate, seedling vigor, growth rate, fruit and seed yield, tillering and/or biomass in plants. The present invention further relates to the use of these nucleic acid molecules and polypeptides in making transgenic plants, plant cells, plant materials or seeds of a plant having plant size, vegetative growth, organ number, plant architecture, growth rate, seedling vigor and/or biomass that are altered with respect to wild type plants grown under similar conditions.

This invention is in the field of neurology. Specifically, the invention relates to the discovery and characterization of molecular components that play a role in neuronal demyelination or remyelination. In addition, the invention relates to the generation of an animal model that exhibits hypomyelination. The compositions and methods embodied in the present invention are particularly useful for drug screening and/or treatment of demyelination disorders.
US07884259B2 Absorbent article
An absorbent article including a fiber aggregate formed by opening the tow, a super absorbent polymer particle, and a sheet covering these components. The super absorbent polymer particle are bonded to the sheet with an adhesive that is applied in a continuous plane to the entire surface or the substantially entire surface at least at the portion to be provided with the super absorbent polymer particle in this sheet.
US07884254B2 Dehydrochlorination of hydrochlorofluorocarbons using pre-treated activated carbon catalysts
The present disclosure provides methods for pre-treating activated carbon before it is used in a dehydrochlorination process. The methods can comprise mixing the activated carbon with an acid, an oxidizing agent in a liquid phase, or an oxidizing agent in a gas phase. Activated carbons undergoing one or more of these methods can exhibit improved stability during the dehydrochlorination process.
US07884253B2 Methods and apparatus for selectively producing ethanol from synthesis gas
The invention provides methods and apparatus for selectively producing ethanol from syngas. As disclosed herein, syngas derived from cellulosic biomass (or other sources) can be catalytically converted into methanol, which in turn can be catalytically converted into acetic acid or acetates. Finally, the acetic acid or acetates can be reduced to ethanol according to several variations. In some embodiments, yields of ethanol from biomass can exceed 100 gallons per dry ton of biomass.
US07884251B2 Industrial process for separating out by-produced alcohols
It is an object of the present invention to provide a specific industrial separation process that enables an alcohol to be separated out efficiently and stably for a prolonged period of time from a large amount of a low boiling point reaction mixture containing a by-produced alcohol when mass-producing aromatic carbonates on an industrial scale by subjecting a dialkyl carbonate and an aromatic monohydroxy compound to transesterification reaction in a reactive distillation column in which a catalyst is present. Although there have been various proposals regarding processes for the production of aromatic carbonates by means of a reactive distillation method, these have all been on a small scale and short operating time laboratory level, and there have been no disclosures whatsoever on a specific process or apparatus enabling mass production on an industrial scale to be carried out stably for a prolonged period of time. Moreover, there have been no disclosures on a specific process or apparatus enabling the alcohol by-produced when producing aromatic carbonates the an industrial scale using a reactive distillation system to be separated out efficiently and stably for a prolonged period of time on an industrial scale of not less than 200 kg/hr. According to the present invention, there is proposed a specific process using a continuous multi-stage distillation column having a specified structure enabling the above object to be attained.
