Abstract: An apparatus and a method stabilize a charging current when recharging a battery in a device that uses a rechargeable battery. The device includes a charge module and a controller. The charge module provides a charging current to the battery, and operates in at least one of a Constant Current (CC) mode that maintains the charging current at a fixed value while the battery is charged, and a Constant Voltage (CV) mode that maintains a battery voltage at a reference value. The controller controls the charge module to operate in the CC mode when starting charging, controls the charge module to operate in the CV mode when the battery voltage reaches the reference value, and controls the charge module to operate in the CC mode for at least one time duration after the battery voltage reaches the reference value.

Abstract: A portable terminal includes a charging control system. The system supplies electric power to the battery. If the battery is charged completely, the system stops charging the battery temporarily, adjusts the termination current, and then charges the battery to the preset second charge capacity. The system can recharge the battery if the battery of the second charge capacity under goes a natural discharge for a certain time period by a certain rate of the second charge capacity, for example, 1%, or if the maximum voltage corresponding to the second charge capacity drops by 1% of the maximum voltage. Therefore, the system can retail the maximum charged state of the battery.

Abstract: The present invention is related to electronic equipment having a controlling unit and a subordinate unit, and more particularly, to an apparatus for controlling power and signal of electronic equipment having a controlling unit and a subordinate unit which can reduce power consumption by turning off power to an unused subordinate unit at a certain period of time, and effectively reducing leakage current that flows from the controlling unit to the subordinate unit in the apparatus for extending battery usage time, and prevent distortion of waveforms of the subordinate unit's input end being sent from the controlling unit.

Abstract: A circuit and method of processing malfunction of a hall effect switch used for recognition of an open/close state of a flip or folder of a terminal. The circuit includes an output terminal of the hall effect switch for outputting a first-state or second-state signal that indicates the open/close state of the flip or folder by sensing change of a magnetic field according to opening/closing of the flip or folder, a flip/folder-state input terminal for transferring the first-state or second-state signal to a control section of the terminal, a first pull-up resistor connected to the flip/folder-state input terminal, a ripple-removing capacitor connected to the flip/folder-state input terminal, and a second resistor of which one terminal is connected to the output terminal of the hall effect switch and the other terminal is connected to a connection point of the first resistor and the capacitor.

Abstract: An apparatus and method for correctly sensing the state of a 4-pole earmicrophone having two receiver terminals and two common terminals for a microphone and a switch in a mobile terminal. The mobile terminal senses a switch-on of the earmicrophone by mechanical connection between an earmicrophone jack and a jack connector during an earmicrophone connection. The mobile terminal stores information about an earmicrophone state detected by the jack connector. Upon detection of the switch-on of the earmicrophone, the mobile terminal reads the earmicrophone state information from the memory. If the read earmicrophone state indicates earmicrophone disconnection, the mobile terminal mutes transmission and reception, determining that the switch-on is a transient phenomenon.

Abstract: A method is provided for recognizing a key in a terminal apparatus having a key matrix structure. The method according to the invention includes the steps of recognizing pushing of and detaching from a key by using a difference between a previous key status value on the key matrix and a current key status value according to a change of the key status, and obtaining a positional value of an inputted key on the key matrix by using a relational expression considering difference values between adjacent rows in each line and between adjacent lines in each row and a difference between the previous key value and the current key value.
