    摘要: A wireless power transmitting apparatus converts rotational energy of an axle to electrical energy, transfers the electrical energy to a transmitting coil of the wireless power transmitting apparatus through a power transfer connection pin that connects the inside of the wheel and the outside of the wheel of a vehicle, and wirelessly transmits the electrical energy to the sensor using resonance between a transmitting coil of the wireless power transmitting apparatus and a receiving coil of the sensor in order to use it as a driving power source of a sensor that detects a state of a tire.

    摘要: A receiving apparatus for an RFID reader estimates channel coefficients for each of a plurality of receiving antennas based on tag response signals received via a plurality of receiving antennas, compensates the tag response signals received via the plurality of receiving antennas based on the channel coefficients estimated for each of a plurality of channel estimators, combines the compensated tag response signals for each of the plurality of receiving antennas to generate a combined signal, and detect bits in the combined signal.

    摘要: Provided are a multiwavelength photoelectric smoke detection apparatus and method, which reduce non-fire alerts by distinguishing smoke caused by actual fire occurrence and non-fire smoke occurring in daily life when a suspected fire event occurs. The multiwavelength photoelectric smoke detection apparatus includes a chamber in which a smoke inlet is formed, a light emitter for generating light with multiple wavelengths, a light receiver for detecting scattered light due to smoke particles, a controller for turning a light source of the light emitter on and off and detecting a scattered light signal from the light receiver, and a fire determination part for determining whether an amplitude of the detected scattered light signal exceeds a threshold value and generating an alarm.
