Abstract: Disclosed is a hybrid system in which a solid oxide electrolyzer cell (SOE), a solid oxide fuel cell (SOFC), and a carbon capture system (CCS) are coupled to each other, and more particularly to an SOE-SOFC-CCS hybrid system configured such that a solid oxide electrolyzer cell, a solid oxide fuel cell including a burner configured to burn off-gas, and a carbon capture system are systematically operated and such that by-products and waste heat generated as the result of operation thereof are recycled, whereby consumption of hydrogen and a fuel necessary for power production is minimized.

Abstract: A camera module is provided. The camera module includes a first lens module including at least one lens and having light incident thereinto, a second lens module including at least one lens, and a reflection module having a reflective member configured to guide light that has passed through the first lens module to the second lens module, and perform an optical image stabilization operation. A light blocking member is disposed between the first lens module and the reflection module, and the first lens module is coupled to the reflection module and is configured to move together with the reflection module.

Abstract: A communication apparatus includes a data collecting unit for obtaining log information about a state of a battery from a battery management system that manages the battery, a first storing unit including reference log information for determining abnormality of the battery, and a diagnosing unit for diagnosing abnormality of the battery by comparing the log information about the state of the battery with the reference log information.

Abstract: According to at least one aspect, the present disclosure provides a piston pump comprising: a piston unit configured to reciprocate by driving of a motor cam; a sleeve unit disposed to surround at least a part of the piston unit and having a space in which brake oil is stored; and a check valve unit facing the sleeve unit and discharging the brake oil to an outside of the sleeve unit when a pressure of the brake oil increases, wherein the piston unit includes a first piston having a first end in contact with the motor cam and reciprocating, a second piston having a first end coupled to a second end of the first piston and configured to press the brake oil, and a spring cap coupled to a second end of the second piston and disposed to accommodate an inlet spring therein.

Abstract: A piston pump for a brake may include: a piston moved by rotation of a motor cam, and movably installed in a piston housing; a sleeve installed in a shape to cover an end of the piston, and having an inner space for storing brake oil moved from the piston; an airtight mounting part coupled to the end of the piston, and blocking brake oil from moving between the piston and the sleeve; a return spring having both sides contacted with the sleeve and the airtight mounting part, and elastically pressing the airtight mounting part toward the motor cam; an inlet ball pressed toward the piston by an inlet spring, and installed in contact with the airtight mounting part; and a check valve installed at a position facing the sleeve, and discharging brake oil to the outside of the sleeve when the pressure of the brake oil rises.
