    • The invention mainly relates to the mass spectrometric identification of pathogens in blood cultures from blood-stream infections (septicemia). The invention provides a method with which microbial pathogens can be separated in purified form from blood after a relatively brief cultivation in a blood culture flask, without any interfering human proteins or any residual fractions of blood particles such as erythrocytes and leukocytes, and can be directly identified by mass spectrometric measurement of their protein profiles. The method is based on the use of relatively strong tensides to destroy the blood particles by dissolving the weak cell membranes and most of the internal structures of the blood particles; in spite of the fact that tensides are regarded as strong ionization inhibitors in MALDI and other ionization processes required for mass spectrometric measurements. This method allows unknown pathogens to be obtained in their pure form by centrifuging or filtration and to be identified on the taxonomic level of species or subspecies. Problems with DNA from high levels of leukocytes can be resolved by special measures. After sufficient cultivation, the identification in a mass spectrometric laboratory takes only half an hour.
    • 本发明主要涉及血流感染(败血病)血液培养物中病原体的质谱鉴定。 本发明提供了一种在血培养瓶中比较短暂的培养后,将微生物病原体与血液分离的方法,其中没有任何干扰的人类蛋白质或血液颗粒如红细胞和白细胞的任何残留部分,并且可直接 通过其蛋白质谱的质谱测定来鉴定。 该方法基于使用相对较强的表面活性剂通过溶解弱细胞膜和血液颗粒的大部分内部结构来破坏血液颗粒; 尽管在MALDI和质谱测量所需的其他电离过程中,表面活性剂被认为是强电离抑制剂。 该方法允许通过离心或过滤以其纯形式获得未知的病原体,并根据物种或亚种的分类级别进行鉴定。 通过特殊措施可以解决高水平白细胞DNA的问题。 在充分培养后,质谱实验室的鉴定只需半小时。

    • A dual-stage method is provided for identifying a microbe by, for example, its species or its subspecies. The method includes measuring a mass spectrum of the microbe using a mass spectrometer, calculating indicators for similarities between reference mass spectra in a library and the measured mass spectrum, selecting a group of reference mass spectra similar to the measured mass spectrum, determining a distinguishing weight for each mass signal of the reference mass spectra in the group, where the distinguishing weights emphasize differences between the reference mass spectra in the group, and calculating indicators for similarities between the reference mass spectra in the group and the measured mass spectrum as a function of the distinguishing weights.

    • In a method for reliably monitoring the speed of a moveable coordinate measuring device, a first value of the speed is calculated from measured values of the coordinate measurement system. The measured values contain information on positions of the coordinate measuring device. The measured values are further used to determine the coordinates of a measurement object. A second value of the speed is ascertained from measurement signals of at least one additional movement sensor. The measurement signals can also be used for controlling a drive device of the coordinate measuring device. A fault signal can be generated if the first value and/or the second value deviate from one another, from a predetermined value and/or a limit value according to a predefined criterion.
    • 在可靠地监视可移动坐标测量装置的速度的方法中,根据坐标测量系统的测量值来计算速度的第一值。 测量值包含关于坐标测量装置位置的信息。 测量值进一步用于确定测量对象的坐标。 速度的第二值由至少一个额外的运动传感器的测量信号确定。 测量信号也可用于控制坐标测量装置的驱动装置。 如果第一值和/或第二值根据预定标准从预定值和/或极限值彼此偏离,则可以产生故障信号。

    • An eating utensil with a spoon shell fastened to a handle enables handicapped people, who have, e.g., only one usable hand, to reduce in size pieces of food, e.g., meat, by cutting into bite-sized pieces. To achieve this, the spoon shell (1, 31) and the handle (6) are of a two-part design. The spoon shell (1) has a first shell part (2) with a first handle shaft (4) and a second shell part (3) with a second handle shaft (5). The respective shell parts (2, 3) and handle shafts (4, 5), which are rigidly connected to one another, are connected to one another by a scissor hinge (7) and can be moved against one another in a scissor-like manner. The shell parts (2, 3) have cutting edges (8, 9) cooperating in a scissor-like manner.
