摘要： An augmented reality (AR) device and a method of predicting a pose in the AR device is provided. In the augmented reality (AR) device inertial measurement unit (IMU) values corresponding to the movement of the AR device are obtained at an IMU rate, intermediate 6-degrees of freedom (6D) poses of the AR device are estimated based on the IMU values and images around the AR device via a visual-inertial simultaneous localization and mapping (VI-SLAM) module, and a pose prediction model for predicting relative 6D poses of the AR device is generated by performing learning by using a deep neural network.

摘要： The present disclosure relates to a technical idea of reducing the surface temperature of a material or temperature under a material by emitting heat under a device to the outside by absorbing and emitting long-wavelength infrared light corresponding to the wavelength range of the atmospheric window while minimizing absorption of light of the solar spectrum. More particularly, the present disclosure relates to a technology for providing a radiative cooling device having a multilayer structure that is capable of increasing sunlight reflection through differences in the refractive indexes of the device-forming materials while performing selective emission over the wavelength range of the atmospheric window using a radiative cooling device having a multilayer structure composed of polymers and inorganic materials.

摘要： The present invention relates to thermally and chemically stable quantum dots encapsulated with functional polymeric ligands, a thermally stable quantum dot optical film using the encapsulated quantum dots, and a method for preparing the encapsulated quantum dots. The coating of the surface of the quantum dots with the polymer stabilizes the quantum dots and improves the durability and dispersibility of the quantum dot optical film, achieving markedly improved efficiency of photoluminescent quantum dot devices. Therefore, it is anticipated that the present invention will pave the way for practical use of quantum dots in a variety of light-emitting applications, particularly in high power light-emitting sources, to find commercial application in various fields, including displays, bioimaging, lightings, and photovoltaic cells.
