Provided are a training data creation method and device, and a defect inspection method and device capable of securing the accuracy of defect inspection even though the number of samples of a defect to be used in creating training data is small. The training data creation method includes acquiring a training-use image including a received light image created based on reflected light or transmitted light from an inspection object having a defect obtained by irradiating the inspection object with light rays or radiation, executing frequency distribution analysis on the training-use image, receiving an input of a parameter for designating a frequency bandwidth, selecting a frequency bandwidth signal from an analysis result of the frequency distribution analysis according to the frequency bandwidth designated by the parameter, acquiring defect information indicating a defect for an image corresponding to the frequency bandwidth signal, and creating training data to be used in learning of a defect inspection device, which inspects a defect of the inspection object, based on the defect information.

A method for in-ova fertilisation determination and gender determination on a closed egg. The aim is to specify a method for the in-ovo fertilisation determination and gender determination on a closed egg. This aim is achieved by a method in which a closed egg is positioned, candled and/or illuminated, next an image of the closed egg is recorded, then the captured data are evaluated and the position of the cardiovascular system located in the egg is calculated. A detection unit is adjusted via the calculated position of the cardiovascular system by means of a positioning unit and subsequently the blood is stimulated, then the blood-specific and blood-foreign absorption spectra are detected and selected, the fertilisation is ascertained and then the spectra containing blood-foreign information are compensated by a compensation method and the spectra are classified for sex determination.

A substrate and a covering structure coupled to the substrate form a chamber. The chamber houses an emitter configured to emit a radiation, a resonant reflector, a detector, and a fixed reflector. First and second windows extend through the covering structure. The emitter, the first reflector and the second reflector are reciprocally arranged such that radiation emitted from the emitter is reflected by the fixed reflector towards the MEMS reflector for further reflection towards the first window to form an output signal. The detector and the second window are reciprocally arranged such that an incoming radiation passing through the second window is received by the detector. The electronic module can be used for a 3D sensing application.
