  • Patent number: 12159227
    Abstract: Disclosed are a system for predicting optical properties of molecules based on machine learning and a method thereof. More particularly, the system for predicting optical properties according to an embodiment includes a preprocessor that receives molecular information of a target molecule and surrounding molecules, and vectorizes the molecular information of a target molecule and surrounding molecules; a feature extractor that receives the vectorized information of the target molecule and surrounding molecules and extracts the features of the target molecule and surrounding molecules; an integrated feature extractor that receives both features of the target molecule and surrounding molecules and extract the integrated features of the target molecule and surrounding molecules by using an algorithm; and an optical property predictor that receives the integrated features of the target molecule and surrounding molecules and predicts optical properties of the target molecule affected by surrounding molecules.

  • Patent number: 11498477
    Abstract: A rotation center decoupling type aiming lamp applied to a vehicle includes an aiming device in which an aiming axis spaced apart from an aiming point reference line of an aiming point axis at a distance of an aiming adjustment height is operated as a rotation center of the reflector, and an aiming angle is changed through an aiming point axis to which the reflector is attached by a reflector bracket, such that the rotation center of the reflector adjusting a light radiation direction may be formed at a position above or ahead of the aiming point reference line, thereby reducing an occupation space of the aiming device and securing stability of the aiming driving, and particularly, a sufficient rear shock absorption space may also be secured in the aiming lamp, thereby securing structural robustness while satisfying low-speed collision regulations.
