Abstract: Optical data is collected from an optical sensor of a dual wavelength, and in order to detect the fire from the collected optical data, an average value of a first wavelength, an average value of a second wavelength, and a ratio of the average values of the two wavelengths are calculated, and an amount of change of a slope of the ratio is used to detect the fire and determine the fire occurrence time. From the determined fire occurrence time, fire features are extracted from the optical data in real time according to defined rules to configure a data set. The data set may be used for learning and inference techniques to identify a fire or non-fire, a fire source, a combustion material, and the like.

Abstract: A transmission leakage signal offset apparatus of a radio frequency identification (RFID) reader is disclosed. The transmission leakage signal offset apparatus may include a signal divider to divide a received signal of the RFID reader, the received signal including a transmission leakage signal, and to transmit the divided received signal to a signal combiner and an injection locked oscillator (ILO); a signal synchronizer to synchronize a phase of the ILO with a phase of the transmission leakage signal; a phase controller to control a phase difference between the received signal of the RFID reader and an output signal of the ILO; and a signal combiner to combine the received signal of the RFID reader and the output signal of the ILO, between which the phase difference is controlled.
