Abstract: A lithium secondary battery includes a cathode including a cathode active material that contains lithium metal oxide particles, an anode facing the cathode, and a non-aqueous electrolyte solution including a non-aqueous organic solvent that contains a fluorine-based organic solvent and a lithium salt. A ratio of the number of moles of lithium contained in each of the lithium metal oxide particles to the total number of moles of metals excluding lithium contained in each of the lithium metal oxide particles is 1.05 or more. A content of the fluorine-based organic solvent is in a range from 5 vol % to 60 vol % based on a total volume of the non-aqueous organic solvent.

Abstract: A cathode active material for a lithium secondary battery according to an embodiment includes lithium metal oxide particles containing lithium and nickel, and containing a small amount of cobalt or no cobalt. An average particle diameter, a modulus and a hardness of the lithium metal oxide particles are adjusted to satisfy a desired relation.

Abstract: Disclosed are a method and apparatus for manipulating an object in virtual or augmented reality based on a hand motion capture apparatus providing haptic feedback. The method of manipulating an object in virtual or augmented reality based on a hand motion capture apparatus providing haptic feedback includes receiving a value of a sensor at a specific position in a finger from the hand motion capture apparatus, estimating a motion of the finger based on the value of the sensor and adjusting a motion of a virtual hand, detecting contact of the adjusted virtual hand with a virtual object, and upon detecting the contact with the virtual object, providing feedback to the user using the hand motion capture apparatus, wherein the virtual hand is modeled for each user.

Abstract: An electronic apparatus is provided. The electronic apparatus includes a memory configured to store content schedule information for each content provider, a transceiver and a processor configured to receive content identification information from an external apparatus and time information regarding a time when the content identification information is obtained through the transceiver, identify a content provider corresponding to the content identification information based on the content identification information, the time information and the content schedule information, obtain content schedule information corresponding to the identified content provider from the memory and provide the content schedule information to the external apparatus.

Abstract: A method for performing occlusion queries is disclosed. The method includes steps of: (a) a graphics processing unit (GPU) using a first depth buffer of a first frame to thereby predict a second depth buffer of a second frame; and (b) the GPU performing occlusion queries for the second frame by using the predicted second depth buffer, wherein the first frame is a frame predating the second frame. In accordance with the present invention, a configuration for classifying the objects into the occluders and the occludees is not required and the occlusion queries for the predicted second frame are acquired in advance at the last of the first frame or the first of the second frame.
