摘要： PROBLEM TO BE SOLVED: To improve determination accuracy of inside and outside of an area in area limited radio using a magnetic field.SOLUTION: A mobile terminal device 1 compares Vrcv1 with Vth1 (S3) when the Vrcv1 and Vrcv2 are detected, and if Vrcv1≤Vth1 (S3: NO), it determines that "the mobile terminal device 1 is outside of a radio communication area R1" and returns to a standby state (S1). If Vrcv1>Vth1 (S3: YES), the mobile terminal device 1 compares the Vrcv2 and Vth2 (S5), and if Vrcv2≥Vth2 (S3: NO), it determines that "the mobile terminal device 1 is outside of the radio communication area R1" and returns to the standby state (S1). If Vrcv2

摘要： PROBLEM TO BE SOLVED: To accurately obtain positional information of a mobile phone, using optical wireless communication by means of illumination light.
SOLUTION: In Figure, an emergency light or a guiding light (a lighting device) 10, which is turned on 24 hours a day, emits a visible light (illumination light) modulated, based on the information of its location. The mobile phone 20 with a visible light receiving unit (for example, camera or the like) can obtain positional information, by receiving and demodulating the visible light. When an emergency call is placed (for example, a call to police dial 110 or to fire station dial 119), the positional information obtained is automatically added to voice information as data communication.

摘要： PROBLEM TO BE SOLVED: To suppress increase of consumption current when a radio communication function and an infrared communication function are simultaneously executed. SOLUTION: It is judged whether a radio communication function part 104 is in the middle of radio communication or not and driving current of a light emitting element of an infrared communication function part 102 is controlled based on the judgment. Since the driving current of the light emitting element of infrared communication is controlled in association with operation of the radio communication function part 104, a condition that the infrared communication is possible can be relieved. In a limit of output of the light emitting element, the driving current of the single light emitting element is controlled, the plural light emitting elements different in the outputs is selected and driven.

摘要： PROBLEM TO BE SOLVED: To increase a battery operating time by setting an optimal infrared ray transmission intensity at a communication terminal having an infrared ray port when conducting infrared ray communication with an external terminal. SOLUTION: A CPU 40 controls a level control section 46c to increase an infrared ray transmission intensity of a frame for each opposite terminal find-out procedure that is repeated for each prescribed time until an opposite terminal on an infrared ray interface is found out prior to voice or data communication with an external terminal and fixes the infrared ray transmission intensity of the frame to a prescribed value after the procedure of finding out the opposite terminal by using the infrared ray transmission intensity when the opposite terminal is found out for a reference intensity. Since the infrared ray transmission intensity for infrared ray communication with the external terminal is optimally fixed, the operating time of the mobile communication terminal is extended through the extended service life of the battery of the mobile communication terminal.

摘要： PROBLEM TO BE SOLVED: To allow even a physically handicapped person or a small child to readily use the system and at low cost. SOLUTION: When a terminal 10 connected to a telephone line 1 in this telephone system receives infrared rays outputted from the communication equipment 30, a coding circuit 26 extracts a voice signal and a data signal from the received signal separately and sends them to the telephone line 1, a decoding circuit 27 separately encodes the voice signal and the data signal received from the telephone line 1, and an infrared-ray signal modulated by the coded signal is outputted to the infrared ray communication equipment 30.
