WIRELESS COMMUNICATION TERMINAL SUPPLYING DIRECTION INFORMATION BY USING MAGNETO-IMPEDANCE SENSOR AND METHOD THEREOF - THE TERMINAL PROVIDES EXACT DIRECTION INFORMATION REGARDLESS OF THE STATE OF A WIRELESS COMMUNICATION NETWORK AND CAN BE EASILY INTERWORKED WITH A NAVIGATION SYSTEM

摘要

PURPOSE: A wireless communication terminal supplying direction information by using a magneto-impedance sensor is provided to enable a magneto-impedance sensor to detect the strength of a magnetic field to convert an analog signal into a digital signal, and to transmit the digital signal to a CPU, thereby supplying exact direction information by using the magneto-impedance sensor. CONSTITUTION: A CPU(12) drives and controls a wireless communication terminal, controls a magneto-impedance sensor(19) according to a direction information request signal, receives a signal corresponding to the strength of a magnetic field, and generates direction information. A storage(14) stores a program for driving the wireless communication terminal and a program for calculating the direction information. The magneto-impedance sensor(19) detects the strength of the magnetic field, and transmits the corresponding signal to the CPU(12). A voice output device(15) outputs the direction information.
