Abstract: Provided is an artificial intelligence system. The system includes a first sensor configured to generate a first sensing signal during a sensing time, a second sensor disposed adjacent to the first sensor and configured to generate a second sensing signal during the sensing time, a pre-processing unit configured to select valid data according to a magnitude of a differential signal generated based on a difference between the first sensing signal and the second sensing signal, and an artificial intelligence module configured to analyze the valid data to generate result data.

Abstract: A transceiver includes a transmission module for generating an output signal, a controller for controlling the transmission module to allow an output signal to have one of a first frequency and a second frequency, a reception module for controlling the controller to allow a control signal to be outputted based on completion information received from the outside. The transmission module outputs an output signal having a first frequency to perform human body communication. When the reception module receives completion information, the transmission module outputs an output signal having a second frequency in response to the control signal in order to perform wireless communication. The first frequency is lower than the second frequency.
