Abstract:
1. A short-range wireless communication apparatus comprising: a magnetic field strength detector detecting magnetic field strength from a carrier wave by extracting direct-current potential from the carrier wave used for short-range wireless communication; a magnetic field strength notification device notifying a user of the magnetic field strength detected by the magnetic field strength detector, the magnetic field strength notification device including a light-emitting device which emits light with a brightness proportional to a detected magnetic field strength, the light-emitting device including a first lighting element having a first color and a second lighting element having a second color, and the magnetic field strength notification device increasing a duty cycle of the first lighting element in proportion to the detected magnetic field strength and decreasing a duty cycle of the second lighting element in proportion to the detected magnetic field strength; a communication detector detecting signal communication from a carrier wave used for short-range wireless communication, the light-emitting device blinking the first lighting element and the second lighting element during an entire time that the communication detector detects signal communication with a duty cycle in proportion to the detected magnetic field strength; and a magnetic field strength notification signal generator generating a magnetic field strength notification signal for operating the magnetic field strength notification device in accordance with the magnetic field strength detected by the magnetic field strength detector, the magnetic field strength notification signal generator converting the magnetic field strength detected by the magnetic field strength detector into a brightness adjustment signal for the light-emitting device and providing the brightness adjustment signal of the magnetic field strength notification signal to the light-emitting device.
