Abstract: A method of driving an electronic device includes displaying a plurality of fingerprint recognition icons on a display device configured to perform fingerprint recognition, and releasing a lock state of the display device through a fingerprint authentication process upon determining at least one first fingerprint recognition icon among the plurality of fingerprint recognition icons is touched. The plurality of fingerprint recognition icons include at least one first fingerprint recognition icon configured to support the fingerprint recognition and at least one second fingerprint recognition icon configured to not support the fingerprint recognition.

Abstract: A negative electrode active material as well as a method of preparing a negative electrode active material which includes preparing a silicon-based compound including SiOx, wherein 0.5<x<1.3; disposing a polymer layer including a polymer compound on the silicon-based compound; disposing a metal catalyst layer on the polymer layer; heat treating the silicon-based compound on which the polymer layer and the metal catalyst layer are disposed; and removing the metal catalyst layer, wherein the polymer compound includes any one selected from the group consisting of glucose, fructose, galactose, maltose, lactose, sucrose, a phenolic resin, a naphthalene resin, a polyvinyl alcohol resin, a urethane resin, polyimide, a furan resin, a cellulose resin, an epoxy resin, a polystyrene resin, a resorcinol-based resin, a phloroglucinol-based resin, a coal-derived pitch, a petroleum-derived pitch, a tar and a mixture of two or more thereof.

Abstract: A radio frequency identification (RFID) reader includes an RFID module configured to generate a radio frequency (RF) signal, a power divider configured to divide the generated RF signal into a plurality of RF signals having a same power, at least one antenna configured to transmit the divided RF signals, and a sensor configured to detect an object within a predetermined area and transmit a result of the detection of the object to the RFID module.
