    • Disclosed is a method of preparing a sensor for the analysis of a sample fluid, said sample fluid containing one or more target molecules. The method comprises the step of introducing said sample fluid into a chamber equipped with a porous substrate, one or more probe molecules being applied to said porous substrate and said probes being able to specifically bind to said one or more target molecules. The method further comprises the step of moving said substrate and said chamber relatively to each other in order to force said sample fluid through the pores of said porous substrate and to capture the one or more target molecules with the one or more probe molecules. Also disclosed is a sensor for the analysis of a sample fluid.

    • The present invention provides a reaction vessel (20) for a PCR device. The reaction vessel (20) comprises a sample vial (32) defining a reaction chamber (33) for performing PCR and a storage vessel (62) defining a storage chamber (63) for optical detection. The reaction chamber (33) is in fluid communication with a liquid supply port (34) for supplying a liquid sample containing at least one target DNA to the reaction chamber (33). The reaction chamber (33) and the storage chamber (63) are in fluid communication via a spacer element (42) and a porous membrane (51) for hybridization of the at least one target DNA within the liquid sample onto specific immobilised hybridization probes. The lower end of the spacer element (42) extends into the reaction chamber (33), but does not reach the bottom thereof. The upper end of the spacer element (42) is located in proximity of the porous membrane (51), which is made from a material having different physical properties in a dry state and a wet state. In the dry state the porous membrane (51) allows air as well as liquid to pass therethrough. In the wet state the porous membrane (51) still allows the passage of liquid therethrough, but not of air, such that during a PCR the liquid sample remains in the reaction chamber (33) and after the PCR the reaction vessel (20) is configured to force the liquid sample via the spacer element (42) to the porous membrane (51) for hybridization and detection of the at least one target DNA in the liquid sample. Moreover, a PCR device comprising such a reaction vessel (20) as well as a method for performing PCR are described.

    • Determining the fetal heart rate comprises irradiating an ultrasound beam in the direction of the fetal heart. The moving parts of the fetal heart cause a Doppler shift which is used to determine the fetal heart rate via an autocorrelation function. Moving parts of the fetal heart with different velocities and Doppler shifts originating from other physiological sources generate secondary maxima in the autocorrelation function, so that an accurate heart rate determination becomes nearly impossible. This problem is overcome by parallel processing of the demodulated ultrasound signal in various pass-bands, for which purpose the signal is fed to filters (28, 30) of different frequency characteristics. The output of the pass band with the better result is used for fetal heart rate circulation.
    • 确定胎儿心率包括在胎儿心脏的方向照射超声波束。 胎心的运动部分引起多普勒频移,用于通过自相关函数确定胎心率。 以不同速度运动的心脏心脏部分和源自其他生理源的多普勒频移在自相关函数中产生二次最大值,从而几乎不可能进行准确的心率测定。 通过在各种通带中解调的超声信号的并行处理来克服这个问题,为此,信号被馈送到具有不同频率特性的滤波器(28,30)。 胎儿心率循环使用带通效果较好的输出。
