20090002379 | Video decoding implementations for a graphics processing unit - Video decoding innovations for multithreading implementations and graphics processor unit (“GPU”) implementations are described. For example, for multithreaded decoding, a decoder uses innovations in the areas of layered data structures, picture extent discovery, a picture command queue, and/or task scheduling for multithreading. Or, for a GPU implementation, a decoder uses innovations in the areas of inverse transforms, inverse quantization, fractional interpolation, intra prediction using waves, loop filtering using waves, memory usage and/or performance-adaptive loop filtering. Innovations are also described in the areas of error handling and recovery, determination of neighbor availability for operations such as context modeling and intra prediction, CABAC decoding, computation of collocated information for direct mode macroblocks in B slices, reduction of memory consumption, implementation of trick play modes, and picture dropping for quality adjustment. | 01-01-2009 |
20100036292 | OPTIMIZATION AND FEEDBACK CONTROL OF HIFU POWER DEPOSITION THROUGH THE ANALYSIS OF DETECTED SIGNAL CHARACTERISTICS - A system and method for adjusting or selecting the treatment parameters for HIFU signals to treat a target treatment site, and/or to aid in visualizing the likely degree and location of HIFU effects on patient tissue. The system transmits one or more test signals into patient tissue and receives signals created in response to the test signals. The signals are analyzed to determine a response curve of how a characteristic of the signal varies with the one or more test signals. The response curve of the detected signals is used to select a treatment parameter. | 02-11-2010 |
20100106019 | METHOD AND APPARATUS FOR FEEDBACK CONTROL OF HIFU TREATMENTS - HIFU therapy to a desired tissue site is controlled based on detected changes in one or more characteristics of a received backscatter signal resulting from exposure of the tissue to HIFU or other interrogation signals. In one embodiment, the bloom of backscatter signals outward from a treatment region (e.g., towards the HIFU transducer) is detected and monitored. Once the bloom reaches a predetermined location, treatment is stopped. Other signal characteristics such as angular distribution of frequency components in the backscatter signal, changes in reflection, power required to saturate a tissue characteristic, changes in attenuation and changes in a cumulative energy distribution function of the backscatter signal that change as a result of the application of HIFU power are also used to control the delivery of HIFU signals in accordance with other embodiments of the disclosed technology. | 04-29-2010 |
20100228126 | ULTRASOUND TREATMENT AND IMAGING APPLICATOR - An ultrasound treatment system includes an applicator in which a therapeutic ultrasound transducer is surrounded by an annular imaging transducer. Illumination signals generated by the therapy or imaging transducer are sequentially or simultaneously delivered to tissue in a viewing space to create corresponding echo signals that are received by the elements of the annular imaging transducer. These echo signals are analyzed with a processor to produce an image of tissue in the viewing space. | 09-09-2010 |
20130095008 | TUBE AND FLOAT SYSTEMS AND METHODS OF USING THE SAME - This disclosure is directed to systems for analyzing target materials of a suspension. In one aspect, the systems include a tube and a float that is at least partially coated with a coating having a high affinity for target analytes of a suspension. The coating provides an adhesion or an attraction force with the target analytes through chemical means. In another aspect, the coating can be a changeable material that when stimulated by application of an appropriate stimulus attracts and/or attaches the target analytes to the coated surface of the float. In another aspect, a coating applied to the float may also be used to form a sealing engagement between the float and the inner surface of the tube in order to inhibit fluids from flowing past the coated float in the tube. | 04-18-2013 |
20130344507 | SYSTEMS AND METHODS FOR SEPARATING COMPONENT MATERIALS OF A SUSPENSION USING IMMUNOMAGNETIC SEPARATION - This disclosure is directed to systems and methods for immunomagnetic separation of a target analyte of a suspension from the other component materials of the suspension. The system may be composed of a tube, a magnetizable float, and a magnet. The magnetizable float is configured to propagate or introduce a magnetic field. In one aspect, the magnet is included in the magnetizable float. In another aspect, the magnet is external to the magnetizable float. The system may also include a solution containing a particle to conjugate with the target analyte to form a target analyte-particle complex. The particle is capable of being attracted by the magnetic field or magnetic gradient introduced by the magnet. The target analyte-particle complex may be attracted to the magnetizable float. | 12-26-2013 |
