Publication number: 20240380615Abstract: An IoT device according to an embodiment encrypts IoT data using a peripheral device and transmits the IoT data to a server, and a user device requests and obtains necessary IoT data from the server, thereby achieving real-time IoT data sharing. The IoT device performs only relatively low-performance operation of attribute-based encryption to encrypt IoT data collected through a sensor and outsources the remaining high-performance operations of attribute-based encryption to the peripheral device providing external communication network connection to the IoT device to generate a final ciphertext. A user device generates an attribute bloom filter using an access policy thereof, requests and obtains IoT data encrypted according to attribute-based encryption. A cloud server receives and stores IoT data encrypted by the IoT device and the peripheral device according to attribute-based encryption and transmits IoT data retrieved using the attribute bloom filter as a query to the user device.Type: ApplicationFiled: September 16, 2022Publication date: November 14, 2024Inventors: Woo Jin JEON, Dong Hyeon YU, Hsu RUEI-HAU, Je Min LEE, Ji Woong CHOI

Patent number: 8674261Abstract: The present invention relates to a method and apparatus for manufacturing a solar cell module using a laser. In the present invention, a tabbing process for bonding a solar cell and metal electrodes is performed by a local irradiation with a laser, so that the heating area can be localized only to a required zone (bonding area) for the tabbing process, thereby minimizing a direct heating zone which occurs in the process. Therefore, it is possible to reduce the damage such as cracks and breakage due to thermal expansion/contraction of a solar cell which is conventionally configured to have a multi-layered structure made of different materials, to improve the bonding strength and the bonding uniformity, and to reduce the processing time, thereby improving the production efficiency.Type: GrantFiled: November 18, 2008Date of Patent: March 18, 2014Assignee: LG Hausys, Ltd.Inventors: Dong Hun No, Dong Sik Jang, Je Min Yu
