Abstract: The present invention relates to a positive electrode active material and a lithium secondary battery including the same, and more particularly, to a bimodal-type positive electrode active material including a first lithium composite oxide, which is a small particle, and a second lithium composite oxide, which is a large particle, these particles having different particle diameters, wherein the positive electrode active material makes it possible to prevent deterioration in electrochemical properties and stability thereof, which are generated due to non-uniform formation of a coating layer at least partially coating surfaces of the small and large particles, a positive electrode including the positive electrode active material, and a lithium secondary battery using the same.

Abstract: A stereo type distance recognition apparatus and method are provided. The stereo type distance recognition apparatus may include a plurality of sensors to generate a plurality of infrared (IR) signals, a communication unit to insert a set first pattern into each of the plurality of generated IR signals and to transmit the IR signals to an object, and a processor to extract a second pattern from each of signals reflected from the object by the plurality of IR signals, to cancel an interference signal from each of the reflected signals based on a result of a comparison between the first pattern and the second pattern, and to compute a distance from the object based on signals from which the interference signal is cancelled.
