Abstract:
Provided is a method for predicting battery health in consideration of a temperature of a battery management system, the method including: measuring the voltage, current, and temperature of the battery and calculating the initial state of charge (SOC) of the battery by an internal control unit when the operation of the battery management system (BMS) is started; checking whether the battery is in the charged state or in the discharged state by the control unit; calculating the current amount of accumulated discharge by the control unit if the battery is in the discharged state; calculating an accumulated discharge rate capacity by the control unit if the battery is in the charged state and if the amount of accumulated discharge is calculated; calculating the capacity reduction rate of the battery depending on the average usage temperature of the battery by the control unit; calculating a currently available battery capacity ratio by using the capacity reduction rate and the accumulated discharge rate capacity value by the control unit; and calculating and outputting the state of health (SOH) of the battery, which corresponds to the temperature change of the battery, by the control unit based on the battery capacity ratio.

Abstract:
Provided is a method for offloading data traffic by a Mobility Management Entity (MME) in a wireless communication system. The method includes determining a Packet Data Network (PDN) to connect to for providing a service requested by a User Equipment (UE), upon receiving a connection request message requesting connection between the UE and the PDN from the UE, selecting a gateway disposed closest to a Radio Access Network (RAN), sending a permit message permitting a request for connection between the UE and the PDN to the UE, and setting an Evolved Packet Service (EPS) bearer for transmission and reception of data traffic related to a service requested by the UE between the UE and the gateway.
Abstract:
An augmented reality (AR) system includes a data generator configured to generate three-dimensional (3D) data corresponding to a press mold product, and an AR terminal configured to convert the 3D data into AR data. The AR terminal includes a data inputter configured to receive the 3D data and display information corresponding to location information of each node of the 3D data. The AR terminal also includes a data processor configured to convert the 3D data into a form of polygon mesh according to a type of form information of the 3D data and generate AR data in a form of 3D virtual model through matching with the display information. The AR terminal additionally includes a data augmentation part configured to augment and match the AR data on a real product displayed on a camera image, and augment and display the display information for each node, through a user interface (UI).
