Abstract: The present disclosure provides a wearable device that can be attached to or detached from a user. The wearable device includes a first display having a first size, a processor, and a memory storing instructions thereon that, when executed, allow the processor to display, through the first display, a user interface for obtaining a text input, transmit, to an external device that includes a second display having a second size, a request for obtaining the text input through the external device, receive, from the external device, input information related to the text input obtained through the external device, and display the received input information in the user interface.

Abstract: Provided are a semiconductor package and a method of fabricating the same. The semiconductor package includes: a package substrate; a semiconductor chip mounted on the package substrate and electrically connected to the package substrate; a first protective layer covering the semiconductor chip and having flexibility controlled by at least one of a material type, a thickness, a material composition ratio and viscosity of the first protective layer; and a second protective layer arranged on the first protective layer and having flexibility controlled by at least one of a material type and a thickness of the second protective layer, wherein the first protective layer comprises a first binder resin, a first hardener, and a first hardening catalyst. According to the semiconductor package of the inventive concept, protective layers protecting the semiconductor chip have flexibility, and thus, the semiconductor package may be bent.

Abstract: The present invention relates to an apparatus and method for calculating a length of a carbon grounding electrode module, which calculates a grounding electrode module length with the smallest grounding impedance variation depending on frequency variation, with respect to the grounding electrode module having a coaxial structure and being filled therein with a carbon-containing filler, wherein the present invention comprises: configuring two distributed constant circuits into two layers to configure a grounding electrode circuit; receiving the resistivity and relative dielectric constant of ground, the resistivity and relative dielectric constant of the filler, and the inside and outside diameters of the grounding electrode module, as dummy variables; selecting a plurality of frequencies within a frequency variation range; simulating a grounding electrode circuit with the dummy variables with respect to each selected frequency to calculate grounding impedances corresponding to lengths of a grounding electrode

Abstract: An apparatus and method for downloading an update file using a Firmware Over The Air (FOTA) service of a portable terminal are provided. The apparatus includes a controller and a command analyzer. The controller processes to receive a device management command from an update server, the device management command including information indicating the execution or non-execution of update and checksum information for delta information, and performs the firmware update. The command analyzer analyzes the received device management command, and if update execution is necessary, the command analyzer determines if the delta information is information valid for the portable terminal based on the checksum information, before receiving the delta information.

Abstract: The present invention relates to an electrolyte composition for a lead storage battery, which can maintain the performance of a storage battery at low temperature by enhancing the performance and life of a storage battery. It can also be fully charged in a short period of time due to a greater current efficiency. The present invention can extend the life of a storage battery due to its effect of removing white-colored lead sulfate without corrosion at the electrode plates, and may lead to recycling of waste storage batteries ruined by white-colored lead sulfate.
