    • Peptides have been identified that bind with high affinity to body surfaces, such as, hair, skin, nails, teeth, gums, corneal tissue, and oral cavity surfaces. Peptide-based body surface reagents formed by coupling a body surface binding peptide to a benefit agent are described. The peptide-based body surface reagents include peptide-based hair conditioners, hair colorants, skin conditioners, skin colorants, nail colorants, and oral care reagents. The peptide-based hair conditioners and hair colorants are comprised of a hair-binding peptide coupled to a hair conditioning agent or a coloring agent, respectively. The peptide-based skin conditioners and skin colorants are comprised of a skin-binding peptide coupled to a skin conditioning agent or a colorant, respectively. The peptide-based nail colorants are comprised of a nail-binding peptide coupled to a coloring agent. The peptide-based oral care reagents are comprised of an oral cavity surface-binding peptide coupled to an oral care benefit agent. In all these compositions, the peptide may be directly coupled to the active agent or the coupling may be via a spacer. Personal care compositions containing these peptide-based body surface reagents are also described.
    • 已经鉴定出已经以高亲和力结合身体表面,例如头发,皮肤,指甲,牙齿,牙龈,角膜组织和口腔表面的肽。 描述了通过将身体表面结合肽偶联到有益剂形成的基于肽的体表试剂。 基于肽的体表试剂包括基于肽的头发调理剂,毛发着色剂,皮肤调理剂,皮肤着色剂,指甲着色剂和口腔护理试剂。 基于肽的护发素和毛发着色剂分别由与头发调理剂或着色剂偶联的毛发结合肽组成。 基于肽的皮肤调理剂和皮肤着色剂分别由与皮肤调理剂或着色剂偶联的皮肤结合肽组成。 基于肽的指甲着色剂由与着色剂偶联的指甲结合肽组成。 基于肽的口腔护理试剂由与口腔护理有益剂偶联的口腔表面结合肽组成。 在所有这些组合物中,肽可以直接与活性剂偶联,或者偶联可以经由间隔物。 还描述了含有这些基于肽的体表试剂的个人护理组合物。

    • A method and system of performing postfiltering in the frequency domain to improve the quality of a speech signal, especially for synthesized speech resulting from codecs of low bit-rate, is provided. The method comprises LPC tilt computation and compensation methods and modules, a formant filter gain computation method and module, and an anti-aliasing method and module. The formant filter gain calculation employs an LPC representation, an all-pole modeling, a non-linear transformation and a phase computation. The LPC used for deriving the postfilter may be transmitted from an encoder or may be estimated from a synthesized or other speech signal in a decoder or receiver. The invention may be implemented in a linked decoder and encoder. A separate LPC evaluation unit that is responsible for processing and or deriving the LPC may be implemented within the invention.
    • 提供了一种在频域中执行后置滤波以提高语音信号质量的方法和系统,特别是对于由低比特率的编解码器产生的合成语音。 该方法包括LPC倾斜计算和补偿方法和模块,共振峰滤波器增益计算方法和模块,以及抗混叠方法和模块。 共振峰滤波器增益计算采用LPC表示,全极建模,非线性变换和相位计算。 用于导出后置滤波器的LPC可以从编码器发送,或者可以从解码器或接收机中的合成的或其他语音信号来估计。 本发明可以在链接的解码器和编码器中实现。 负责处理和推导LPC的单独的LPC评估单元可以在本发明中实现。
