Abstract: A blended positive electrode material includes a first positive electrode active material containing a first lithium transition metal oxide and a second positive electrode active material containing a second lithium transition metal oxide, wherein the first lithium transition metal oxide and the second lithium transition metal oxide each have a nickel content of 70 mol % or greater with respect to of all metals excluding lithium, the first positive electrode active material has a greater D50 than the second positive electrode active material, and EELS analysis results for particle surfaces of both the first positive electrode active material and the second positive electrode active material satisfy Equation 1. A method for preparing the blended positive electrode material is also provided.

Abstract: An aerosol generating system according to one embodiment includes a cigarette having a first color band of which color changes in response to humidity, and an aerosol generating device including a main body including an accommodation passage for accommodating the cigarette, a heater for heating the cigarette, a color sensor arranged on one side of the accommodation passage and detecting a color of the first color band, and a controller for determining a humidity state of the cigarette, based on a detected color of the first color band.

Abstract: An apparatus for detecting a vehicle seat position is disclosed. The apparatus includes a hall sensor for detecting a target position according to a flux variation; a first power-supply unit for activating the hall sensor in an active period of a received drive-voltage pulse; and a second power-supply unit for providing an auxiliary power-supply signal to activate the hall sensor in an inactive period of the drive-voltage pulse. Therefore, the apparatus can effectively address two-pin hall sensor's problems caused by hysteresis characteristics.
