Abstract: A positive electrode active material for a secondary battery includes a lithium composite transition metal oxide including nickel (Ni), cobalt (Co), and manganese (Mn), wherein the lithium composite transition metal oxide has a layered crystal structure of space group R3m, includes the nickel (Ni) in an amount of 60 mol % or less based on a total amount of transition metals, includes the cobalt (Co) in an amount greater than an amount of the manganese (Mn), and is composed of single particles.

Abstract: An automatic transmission fluid (ATF) warmer coolant circulation system may include an ATF warmer connected to an engine oil cooler, in which engine coolant is circulated to the ATF warmer to preheat automatic transmission fluid of a transmission below an operation temperature of the ATF warmer.

Abstract: An EGR cooling system for a vehicle may include an EGR cooler having an inlet at a first side and an outlet at a second side thereof, in which a gas channel may be disposed between the inlet and the outlet for heat exchange with coolant in coolant channels, and the outlet may be connected to a water pump, in an engine having a separable cooling system that includes the coolant channels individually formed in each of an engine head and an engine block of the engine, to control the supply of coolant.

Abstract: Provided is a pressure sensor for a touch panel, including a signal input member configured to have conductors patterned thereon in an interdigitated form on a substrate, a spacer disposed at a corner where the conductor patterns are not formed on the substrate of the signal input member, and a piezo film disposed over the spacer, spaced apart from the signal input member, and configured to have a resistance value varied depending on the amount of pressure applied to the piezo film, wherein an interval between the conductor patterns formed in the signal input member and disposed close to the spacer is smaller than an interval between the conductor patterns formed in the signal input member and disposed at the farthest place from the spacer.

Abstract: An automatic transmission fluid (ATF) warmer coolant circulation system may include an ATF warmer connected to an engine oil cooler, in which engine coolant is circulated to the ATF warmer to preheat automatic transmission fluid of a transmission below an operation temperature of the ATF warmer.

Abstract: A pressure sensor for a touch panel includes a signal input member having a conductor patterned on a substrate in an interdigitating shape; a spacer arranged on a brim where the conductor pattern on the substrate of the signal input means is not formed; and a piezo film arranged on the spacer to be spaced apart from the signal input member, a resistance value of which changes according to magnitude of pressure, in which a space (D1) of the conductor pattern of the signal input member placed in an area adjacent to the spacer is smaller than a space (D2) of the conductor pattern of the signal input member placed in an area farthest from the spacer, and an exhaustion hole exposed to outside is formed in an area in which the conductor of the signal input member is not patterned.

Abstract: A touch panel capable of recognizing a key touch includes key entry members touched by a user, a sound output member configured to output sounds, a sound control member electrically connected to the sound output member and the key entry members and configured to output a sound, corresponding to a specific key entry member, through the sound output member when a specific key entry member is entered, and a sound selection member electrically connected to the sound control member and configured to turn on or off the sound control member.

Abstract: A pressure sensor for a touch panel includes a signal input member configured to have conductors, where conductor patterns on one side of the signal input member are formed in parallel in a comb pattern and connected on the lower part, and conductor patterns on the other side of the signal input member are formed in parallel in a comb pattern, connected on the upper part, and arranged in such a way as to be interdigitated with the conductor patterns on the first side, spacers disposed at top and bottom corners in which the conductor patterns are not formed on the substrate of the signal input member, a left support disposed in some region of a corner on the left side in which the conductor patterns are not formed on the substrate of the signal input member, a right support disposed in some region of a corner on the right side in which the conductor patterns are not formed on the substrate of the signal input member.
