Abstract: PURPOSE: A method for displaying residual amount of a battery of a mobile station is provided to timely exchange the battery being used by subdividing residual amount of the battery, thereby improving the reliability of using the mobile station. CONSTITUTION: A mobile station activates telecommunication terminals for performing communications with a current flow counter of a battery, sets up the residual battery amount as a reference value with setting up reference value setting time as reference time(301). The mobile station receives charged current flow, discharged current flow of a cell for temporarily storing in a memory, and calculates elapsed time until receiving charging time or discharging time for temporarily storing in the memory(302). The mobile station confirms whether the charged current flow is more than the discharged current flow(303). If the charged current flow is more than the discharged current flow, the mobile station judges that the cell is in charging state and enables a user to confirm the charging state by displaying the charging state in a liquid crystal screen(304). If the discharged current flow is more than the charged current flow, the mobile station judges that the cell is in discharging state and enables the user to confirm the discharging state by displaying the discharging state in the liquid crystal screen(305). The mobile station calculates current residual amount of the battery by using charged current flow, discharged current flow, error compensated value, and elapsed time(306). The mobile station displays the residual amount of the battery by using Icon or figures(307) and stores the calculated residual amount of the battery and elapsed time from reference time to battery residual amount calculation(308).

Abstract: PURPOSE: A tone generating circuit of an exchange system is provided to generate a tone signal in order that a bus collision is not generated. CONSTITUTION: A clock generator(202) inputs an FS(Frame Sync) signal and a predetermined clock signal, and generates a clock signal for controlling tone data and break-make ratio of a tone kind. An address bus selector(203) selects an address accessing PCM(Pulse Code Modulation) tone data and an address accessing cadence data. A memory access address generator(201) receives the clock signal, and generates the address for accessing the tone data or the cadence data. An idle pattern generator(204) generates an idle pattern signal for inserting the tone data into a corresponding time slot during an off time of the cadence data. A memory(100) reads out the tone data or the cadence data for outputting. A parallel/serial converter(205) converts the tone data and the cadence data into serial data, and inserts the tone data into a corresponding time slot according to a pattern generated from the idle pattern generator(204). The parallel/serial converter(205) decides break-make ratio by the converted cadence data, and outputs the tone data.
