摘要： The present technology discloses a three-phase and single-phase two-way charger. According to a specific example of the present invention, a battery charger having a single-stage structure for a combined use of single-phase and three-phase is implemented without an electrolytic capacitor which lowers the reliability and charging efficiency, to enable a compatible use of single-phase and three-phase external power sources, and to improve charging efficiency and the performance in a wide input/output voltage range by a reduced number of switching elements and a soft switching operation of the switching elements and thus improve the reliability and lifetime. A lightweight charger can be realized by integrating, into a core, at least two of an inductor for removing ripples of the battery charger, a primary side and a secondary side of a transformer, and an inductor for removing noise.

摘要： Disclosed are a 4D printing method using thermal anisotropy and thermal transformation, and the resulting product. The method includes (a) artificially planning transverse printing paths and longitudinal printing paths on a specimen to impose a thermal anisotropy to the specimen, (b) sequentially and alternately forming transversely printed layers and longitudinally printed layers on the specimen by printing a thermoplastic polymer in transverse and longitudinal directions to build a 3D printed product, (c) heating the 3D printed product so that the 3D printed product thermally transforms in a specific direction, and (d) controlling heating time to obtain a 4D printed product having a desired final shape which is formed through the transformation of the 3D printed product over the heating time.

摘要： Provided is a method for creating a virtual reality content, storing the virtual reality content in a transmission buffer, and after that, managing the transmission buffer. A server creates the virtual reality content based on user's motion information, stores the virtual reality content in the transmission buffer and is allowed to modify the virtual reality content stored in the transmission buffer based on subsequently received user's motion information, so that the most recent user's motion information can be appropriately reflected in the virtual reality content. It is possible to provide a more immersive virtual reality service.
