Abstract: The present disclosure provides a method for realizing a new type of stay purpose estimation technology that can estimate the purpose of a user's stay regardless of a label data, departing from a method which predetermines a label data in order to estimate a stay purpose.

Abstract: A pressurizing system capable of actively varying and adjusting the pressure applied to a cell of an all-solid-state battery includes: a pressurizing mechanism provided to pressurize an all-solid-state battery and driven to adjust and vary the pressure applied to the all-solid-state battery; a driving device operated to drive the pressurizing mechanism; and a controller controlling the operation of the driving device so that the pressure to pressurize the all-solid-state battery can be adjusted and varied by the above pressurizing mechanism. When the all-solid-state battery is charged or discharged, the controller controls the operation of the driving device based on a pressure change rate so that the pressure for pressurizing the all-solid-state battery may be adjusted and varied according to the pressure change rate determined based on the state information of the all-solid-state battery.

Abstract: A pouch type all-solid-state battery including a reference electrode is disclosed. In the all-solid-state battery, a potential variation of each electrode is accurately measured because the ion transfer path between the reference electrode and a positive electrode/negative electrode is short. Accordingly, the all-solid-state battery secures a desired cell performance while having battery specifications similar to actual battery specifications.

Abstract: Disclosed are a motor hotspot location detecting device and a motor hotspot location detecting method using brainwaves, by which a location of a motor hotspot may be detected based on brainwaves, and a transcranial electrical stimulation device using the same. The motor hotspot location detecting device using brainwaves includes a plurality of brainwave measuring electrode that measures brainwaves generated in the target object at different locations and collects brainwave data, and a motor hotspot location detecting part that detects the location of the motor hotspot based on the brainwave data collected by the plurality of brainwave measuring electrodes.

Abstract: An all-solid-state battery system is disclosed, the system comprising an all-solid-state battery comprising a plurality of cells arranged in a closed inner space of a pressurization chamber and a pressurizing fluid filled in the closed inner space of the pressurization chamber, a state detector configured to detect state information of the all-solid-state battery, a controller configured to output a control signal configured for controlling a pressure applied to the plurality of cells by the pressurizing fluid in the inner space of the pressurization chamber based on the state information of the all-solid-state battery detected by the state detector, and a pressurizing device configured to control the pressure applied to the plurality of cells by the pressurizing fluid according to the control signal outputted by the controller.

Abstract: An all-solid-state battery, in which a cathode part and an anode part are coupled in a state of being folded in a zigzag form, is disclosed. The cathode part has a shape folded in a zigzag form such that the cathode part is divided into unit areas each corresponding to an area of a unit cathode. The anode part has a shape folded in a zigzag form such that the anode part is divided into unit areas each corresponding to an area of a unit anode. A protrusion portion of the cathode part may be inserted into a recessed portion of the anode part, and a protrusion portion of the anode part may be inserted into a recessed portion of the cathode part.

Abstract: The present disclosure relates to a pouch-type all-solid-state battery with a reference electrode inserted and a method for manufacturing the same. The pouch-type all-solid-state battery with a reference electrode inserted includes a unit cell including a negative electrode portion, a positive electrode portion, and a solid electrolyte portion interposed between the negative electrode portion and the positive electrode portion and having a sheet shape; an exterior material provided with a space capable of accommodating the unit cell therein; a reference electrode tap adjacent to the solid electrolyte portion, and formed inside the exterior material; and a reference electrode portion positioned between the solid electrolyte portion and the reference electrode tap, and formed inside the unit cell.
