    • The present invention relates to a light, biodegradable, organic pigment and filler, and a method of manufacturing it. According to the present invention, a solution comprising a starch derivative is first prepared by dissolving the starch derivative into a suitable solvent, and, after that, the solution is brought into contact with a non-solvent to precipitate the starch derivative from the solvent, and, as a result, a dispersion is obtained, one which comprises a precipitate consisting of starch derivative and a liquid phase formed of the solvent and the non-solvent, after which the solvent is removed from the liquid phase and the precipitate is separated from the non-solvent and recovered. The present invention can be used to manufacture both a product comprising 100-300 nm spherical particles, which is suitable for use as a pigment, and a coral-like, porous product which is particularly suitable as a filler.
    • 本发明涉及轻质,可生物降解的有机颜料和填料,及其制造方法。 根据本发明,首先通过将淀粉衍生物溶解在合适的溶剂中制备包含淀粉衍生物的溶液,然后使溶液与非溶剂接触以从溶剂中沉淀淀粉衍生物, 结果得到分散体,其中包含由淀粉衍生物和由溶剂和非溶剂形成的液相组成的沉淀物,然后从液相中除去溶剂,并将沉淀物从 非溶剂并回收。 本发明可以用于制造包含适合用作颜料的100-300nm球形颗粒的产品和特别适合作为填料的珊瑚状多孔产品。

    • A monitoring apparatus comprising a multichannel pressure sensing sensor for measuring a ballistocardiographic signal of a human body is provided. The monitoring apparatus comprises a manner for selecting a time window for heart inter beat interval including two consecutive heart beats to be estimated, defining a spectrum for the signal averaging between at least two measurement channels of the sensor, a cepstrum from the logarithm of the spectrum, and a heart inter beat interval. A method for defining a heart inter beat interval is also provided, where a ballistocardiographic signal of a body is measured with a multichannel pressure sensing sensor, a time window for heart inter beat interval including two consecutive heart beats to be estimated is selected, a spectrum for the signal averaging between at least two measurement channels of the sensor, a cepstrum from the logarithm of the spectrum, and a heart inter beat interval are defined.
