20120106746 | Technique for Estimating Particular Audio Component - Candidate frequencies per unit segment of an audio signal are identified. First processing section identifies an estimated train that is a time series of candidate frequencies, each selected for a different one of the segments, arranged over a plurality of the unit segments and that has a high likelihood of corresponding to a time series of fundamental frequencies of a target component. Second processing section identifies a state train of states, each indicative of one of sound-generating and non-sound-generating states of the target component in a different one of the segments, arranged over the unit segments. Frequency information which designates, as a fundamental frequency of the target component, a candidate frequency corresponding to the unit segment in the estimated train is generated for each unit segment corresponding to the sound-generating state. Frequency information indicative of no sound generation is generated for each unit segment corresponding to the non-sound-generating state. | 05-03-2012 |
20120106758 | Technique for Suppressing Particular Audio Component - A coefficient train processing section, which sequentially generates per unit segment a processing coefficient train for suppressing a target component of an audio signal, includes a basic coefficient train generation section and coefficient train processing section. The basic coefficient train generation section generates a basic coefficient train where basic coefficient values corresponding to frequencies within a particular frequency band range are each set at a suppression value that suppresses the audio signal while coefficient values corresponding to frequencies outside the particular frequency band range are each set at a pass value that maintains the audio signal. The coefficient train processing section generates the processing coefficient train, per unit segment, by changing, to the pass value, each of the coefficient values corresponding to frequencies other than the target component among the coefficient values corresponding to the frequencies within the particular frequency band range. | 05-03-2012 |

20090245460 | Mammography System And Method Employing Offset Compression Paddles, Automatic Collimation, And Retractable Anti-scatter Grid - A mammographic imaging system is optimized for use with a single fixed size flat panel digital image receptor. It accommodates compression devices (paddles) of varying sizes, and positions them properly in the field of view of the image receptor. When a compression paddle with size smaller than the field of view of the image receptor is used, the compression paddle can be shifted laterally in the direction parallel to the chest wall, so as to facilitate different views of different size breasts, and permit the image receptor to image as much of the desired tissue as possible. An automatic x-ray collimator restricts the x-ray illumination of the breast in accordance with compression paddle size and location in the field of view. An anti-scatter grid, mounted inside the image receptor enclosure, just below the top cover of the enclosure, can be retracted out of the field of view of the image receptor for use in magnification imaging. | 10-01-2009 |
20090297006 | Diagnostic system for multimodality mammography - A method includes acquiring first imaging information of a region of interest, said first imaging information providing data correlated to three spatial dimensions of a reference frame including said region of interest; acquiring second projection imaging information of said region of interest, said second imaging information providing data correlated to said reference frame but is lacking information concerning at least one spatial dimension; and processing said first and second imaging information such that said first imaging information is registered with said second imaging information. An apparatus includes a first imaging system for acquiring imaging information of a region of interest, said first imaging information providing data correlated to three spatial dimensions of a reference frame including said region of interest; a second imaging system for acquiring second imaging information of said region of interest, said second imaging information providing data correlated to said reference frame but is lacking information concerning at least one spatial dimension; and a processor for processing said first and second imaging information such that said first imaging information is registered with said second imaging information. | 12-03-2009 |
