Abstract: A device for detecting ovulation using saliva according to the present invention comprises: a device body having a lens disposed in the inner space thereof and a pinhole formed through a side opposite to the lens; a scattering unit coupled to one side of the device body, which has the pinhole formed therein, and configured to scatter light to be supplied to the pinhole; and a sample plate which is separably mounted in the device body so as to be located between the lens and the pinhole and on which saliva is placed, wherein the pinhole is configured to convert light, which passed through the scattering unit, into point light so as to uniformly supply the light to the sample plate, so that saliva crystals formed by drying of the saliva will form a striking contrast with the surrounding portions when the light is scattered by the saliva crystals.

Abstract: An X-ray apparatus includes a control unit configured to acquire orientation information of an X-ray radiation unit and orientation information of X-ray detectors, select an X-ray detector among the X-ray detectors whose orientation information complements or matches the orientation information of the X-ray radiation unit, and generate a control signal; and a communication unit configured to transmit, to the X-ray detector which has been selected, the control signal generated in the control unit so that the selected X-ray detector becomes paired with the X-ray radiation unit for an X-ray imaging of an object.

Abstract: An X-ray apparatus includes an X-ray radiation unit configured to radiate X-rays to an object; and a main control unit configured to acquire orientation information of the X-ray radiation unit and orientation information of an X-ray detector and select the X-ray detector based on the orientation information of the X-ray radiation unit and the orientation information of the X-ray detector.
