20080312917 | METHOD AND APPARATUS FOR PREDICTIVELY QUANTIZING VOICED SPEECH - A method and apparatus for predictively quantizing voiced speech includes a parameter generator and a quantizer. The parameter generator is configured to extract parameters from frames of predictive speech such as voiced speech, and to transform the extracted information to a frequency-domain representation. The quantizer is configured to subtract a weighted sum of the parameters for previous frames from the parameter for the current frame. The quantizer is configured to quantize the difference value. A prototype extractor may be added to first extract a pitch period prototype to be processed by the parameter generator. | 12-18-2008 |
20090281796 | ENHANCED CONVERSION OF WIDEBAND SIGNALS TO NARROWBAND SIGNALS - Wideband speech signals must be converted to narrowband speech signals if the transmission medium or the destination terminal is constructed with narrowband constraints. A typical wideband-to-narrowband conversion method is the elimination of frequencies above 3400 Hz using a low pass filter and a down sampler. However, this method produces a muffled speech sound since the resulting narrowband signal has a flat frequency response. Methods and apparatus are presented herein to enhance the acoustic quality of a wideband-to-narrowband converted signal. A bandwidth switching filter is used to emphasize a mid-range frequency portion of the wideband signal so that the resulting narrowband signal has a non-flat frequency spectrum. | 11-12-2009 |
20100036668 | METHOD AND APPARATUS FOR IMPROVED DETECTION OF RATE ERRORS IN VARIABLE RATE RECEIVERS - A system and method for detection of rate determination algorithm errors in variable rate communications system receivers. The disclosed embodiments prevent rate determination algorithm errors from causing audible artifacts such as screeches or beeps. The disclosed system and method detects frames with incorrectly determined data rates and performs frame erasure processing and/or memory state clean up to prevent propagation of distortion across multiple frames. Frames with incorrectly determined data rates are detected by checking illegal rate transitions, reserved bits, validating unused filter type bit combinations and analyzing relationships between fixed code-book gains and linear prediction coefficient gains. | 02-11-2010 |

20100062961 | Good Foaming Creamy or Paste-Like Cleansers Comprising Floor Levels of Long Chain Lipids or Lipid Mimics - The present invention relates to compositions, especially pastes/creams which have high level of long chain lipids or lipid mimics. These help provide “creaminess”, a desirable rheological characteristic. This is seen from defined viscosity values which define the pastes. In addition, unpredictably, when used in combination with short chain phase inducers, foam values are adequate when it would be expected the lipids would decrease foam. The composition also retains stability from physical separation. | 03-11-2010 |

20110245124 | Personal Wash Cleanser Comprising Defined Alkanoyl Compounds, Defined Fatty Acyl Isethionate Surfactant Product and Skin or Hair Benefit Agent - The present invention relates to super mild surfactant systems used in combination with skin or hair benefit agent(s). Specifically, surfactant systems comprise a combination of specific alkanoyls or mixtures of alkanoyl surfactants with specifically identified fatty acyl isethionate product to provide synergy which reduces irritation (as measured by Patch Testing) so greatly that it is comparable to mildness which normally can be only achieved using very great amounts of benefit agent (e.g., emollient). Use of benefit agent reduces irritation even further. | 10-06-2011 |
20110245125 | Personal Wash Cleanser Comprising Defined Alkanoyl Compounds, Defined Fatty Acyl Isethionate Surfactant Product and Skin or Hair Benefit Agent Delivered in Flocs Upon Dilution - The present invention relates to super mild surfactant systems used in combination with skin or hair benefit agent. Specifically, surfactant systems comprise a combination of specific alkanoyls or mixtures of alkanoyl surfactants with specifically identified fatty acyl isethionate product to provide synergy which reduces irritation (as measured by Patch Testing) so greatly that it is comparable to mildness which normally can be only achieved using very great amounts of benefit agent (e.g., emollient). Use of benefit agent reduces irritation even further. | 10-06-2011 |
20110245126 | Personal Wash Cleanser with Mild Surfactant Systems Comprising Defined Alkanoyl Compounds and Defined Fatty Acyl Isethionate Surfactant Product - The present invention relates to super mild surfactant systems.

20100264364 | METHOD OF BUILDING VISCOSITY AND VISCOELASTICITY IN SURFACTANT SOLUTIONS BY ADDING NANOPARTICLES AND COMPOSITIONS THEREOF - The invention comprises a method of enhancing viscosity and/or viscoelasticity of surfactant solution using nanoparticles. The particle allow a formulator to tailor-make a solution of defined rheology (viscosity and/or viscoelasticity) using nanoparticles to control these properties. Further, the particles allow independent control of each of the variable and further allow the variable to be controlled without use of additional surfactants, polymer and other components traditionally used for this end. The invention also comprises compositions thereof. | 10-21-2010 |
20130150338 | ANTI-DANDRUFF SHAMPOO - The invention relates to an anti-dandruff shampoo comprising:—a) from 0.1 to 5 wt. % of an anti-dandruff zinc salt; b) from 1 to 8 wt. % of an alkyl glycinate and/or alkyl carboxyglycinate; c) from 2 to 16 wt. % of an alkyl sulphate and/or an ethoxylated alkyl sulfate anionic surfactant; and, d) from 1 to 10 wt. % of a fatty acyl isethionate product which product comprises 40 to 80 wt. % fatty acyl isethionate and 15 to 50 wt. % free fatty acid and/or fatty acid salt and to the use of a surfactant system comprising components b) to d) to provide an improvement to the skin stratum corneum barrier. | 06-13-2013 |
