Abstract: The present disclosure provides a display device for inspecting image data that may include a data processing device configured to generate first cyclic redundancy check (CRC) data for a partial area among areas of image data included in a first frame to transmit the image data of the first frame and the first CRC data and a data driving device configured to receive the image data of the first frame and the first CRC data from the data processing device to generate second CRC data for a partial area among areas of the image data included in the first frame on the basis of the image data of the first frame and to compare the first CRC data with the second CRC data to determine whether there is an error in the partial area among areas of the image data included in the first frame.

Abstract: Disclosed is a coded-aperture-based dual particle image fusion apparatus that simultaneously fuses a real-time site image of a radiation source and a reaction image of gamma rays and neutrons to perform nuclide discrimination through the position of radiation, dose per second, and spectrum information, to provide numerical information of dose, and to visualize position information of gamma rays and neutrons through GPS information, whereby it is possible to secure worker safety, and that has a compact size so as to be easily carried, whereby it is possible to create a radiation distribution map based on location movement.

Abstract: A PET-MRI device and a manufacturing method thereof are disclosed. The PET device includes a magnetic resonance imaging (MRI) machine comprising a solenoid coil and a magnetic-field correction coil, wherein the MRI machine has a cylindrical structure or a dipole structure; and a positron emission tomography (PET) machine comprising a PET image sensor, wherein PET image sensor electrodes are formed on one and the other ends of the PET image sensor that have a doughnut shape, and the PET machine has a cylindrical structure or a lattice structure, wherein the PET machine is formed in the MRI machine to allow a direction of an electric field of the PET machine to be parallel to a direction of a magnetic field of the MRI machine.

Abstract: Disclosed is a suspension using continuous and variable leverage, in which a lever serves as a substitute for an air spring. First, a fulcrum located at the center of the lever is connected to a chassis of a vehicle. An impact transmission plate, which has a convex shape toward the lever and is connected to the upper end of a supporter connected integrally with a non-rotating wheel shaft of a wheel, is located under one end of the lever, and transmits an impact from the wheel to the lever. A spring connected to the other end of the lever absorbs the impact transmitted through the lever. The stronger the impact transmitted from the wheel is, the higher the impact transmission plate pushes up the lever. Then, since the upper surface of the impact transmission plate has a convex shape toward the lever, a pressure point, i.e., a contact point between the lever and the impact transmission plate, is shifted toward the fulcrum of the lever.

Abstract: Disclosed is a shock absorber which includes a shock transmission part having a lower end integrally coupled with a non-rotation wheel shaft of a tire and an upper end extending upward, a lever that is in contact with the impact transmission part at its one end and has a support pin at its center, and a shock attenuating part connected to the other end of the shock transmission part to attenuate impact applied to the lever through the shock transmission part during vertical movement of a vehicle. Therefore, an impact press point is moved to a center support pin of the lever as impact from the tire of the vehicle to a spring is increased. As a result, a spring constant is increased in proportion to movement of the pressing contact point, namely, by setting a small spring constant to the small impact, and a large spring constant to the large impact.

Abstract: Disclosed is a noise reduction device, including a pipe-shaped body having an inlet and an outlet, and walls provided in the body to filter noise propagating from the inlet to the outlet, whereby the noise intensity exiting the outlet is less than the noise intensity entering the inlet, the quantity of walls and angle provided between the walls and body being variable to change the performance of noise reduction.
