Abstract: A heat pump boiler is disclosed. The heat pump boiler includes a compressor. The heat pump boiler further includes an exterior heat exchanger that is configured to transfer heat between refrigerant and exterior air. The heat pump boiler further includes an interior heat exchanger that is configured to transfer heat between refrigerant and water. The heat pump boiler further includes a channel change valve that is configured to provide refrigerant compressed by the compressor to the exterior heat exchanger or the interior heat exchanger. The heat pump boiler further includes a first boiler heat exchanger that is configured to heat water that has passed through the interior heat exchanger from heat generated through combustion. The heat pump boiler further includes a second boiler heat exchanger that is configured to transfer heat between refrigerant and gas discharged from the first boiler heat exchanger.

Abstract: A heat pump may include a compressor configured to compress a refrigerant, a first temperature sensor configured to detect an outdoor temperature, a second temperature sensor provided in heating pipes connected to a heating device that performs indoor heating and configured to detect a temperature of fluid flowing through the heating pipes, an outdoor heat exchanger configured to perform heat exchange between outdoor air and a refrigerant, a third temperature sensor configured to detect a temperature of the outdoor heat exchanger, and a controller. The controller may be configured to: control power to a boiler and/or to the compressor based on sensing values of the first, second, and third temperature sensors, calculate an expected efficiency of the heat pump based on the sensing value of the first temperature sensor and an initial target temperature, and control power to the boiler based on the expected efficiency.

Abstract: A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, an actuator, and a first sensor. The second body reciprocates relative to the first body along a first direction between a first position and a second position. The flexible display includes a first region and a second region. As the second body moves from the first position to the second position, the area of the second region, forming the same plane as the first region, increases. The actuator may be operated such that the second body is moved toward the second position in response to free fall being detected by the first sensor, and damage to the flexible display device due to impact with the ground may thereby be reduced.

Abstract: Disclosed herein is a mobile terminal switchable from a first state to a second state by extending in the first direction, including a first frame, a second frame movable from the first frame in the first direction or a second direction opposite to the first direction, a slide frame movable in the first direction or the second direction with respect to the second frame, and a support link having one end hinged to the first frame and an opposite end hinged to the second frame, the support link having a variable length. The mobile terminal may maintain a flat state regardless of change in the state of the mobile terminal by preventing the front surface from being separated or sagging.

Abstract: A mask apparatus includes a mask body having a fan module, a seal defining a breathing space, a pressure sensor sensing air pressure in the breathing space, a mask body cover coupled to the mask body, and a controller that controls a rotation speed of the fan module based on pressure values. The controller is configured to determine breathing information including a maximum pressure value and time point, and a minimum pressure value and time point, determine a breathing state of a user based on the breathing information, determine whether the breathing state is a steady state, determine a tidal volume of the user based on the breathing information, and control the rotation speed of the fan module based on the tidal volume.

Abstract: A mobile terminal includes a first frame, a second frame movable from the first frame in a first direction, a third frame movable in the first direction with respect to the second frame, a flexible display including a first region coupled to the first frame, a second region coupled to the third frame, and a third region bendably disposed between the first region and the second region, and a display frame bendably coupled to a rear surface of the third region. The second frame includes a side portion positioned facing in a third direction perpendicular to the first direction and a guide rail formed on the side portion. The display frame has a guide hook inserted into the guide rail. Even when the display is extended, the mobile terminal keeps the display flat such that the display unit is prevented from being separated or sagged from the frame.
