    摘要: The present invention relates to fluorescence imaging. In order to enhance compatibility with multiple fluorescence channels for calibrating a fluorescence microscope, a calibration slide is provided that comprises a substrate and a pixel layout. The pixel layout comprises a plurality of spaced apart metal nanostructures arranged on a surface of the substrate. The metal nanostructures are arranged to produce plasmon resonances that allow absorbing light at an excitation wavelength to produce photo-luminescence and/or fluorescence light for generating a fluorescent image. The fluorescent image comprises a plurality of pixel intensity values that are provided for calibration of a fluorescence microscope.

    摘要: A breast pump device (1) is equipped with or used in conjunction with an acoustic milk expression assessment system (6) for the purpose of obtaining an indication about a fat content of expressed milk. The acoustic milk expression assessment system (6) includes an acoustic sensor (61) and a processor (62) configured to process an acoustic signal received from the acoustic sensor (61) during operation of the breast pump device (1) when a milk receptacle (4) is used with the device (1). By recording sound during a pumping session, it is possible to determine a frequency shift in the sound of droplets falling down in the receptacle (4) and hitting a surface of the milk contained by the receptacle (4) with respect to a reference situation of a liquid having 0% fat content, which can be taken as a factor in estimating a value related to the fat content of the milk.
