Abstract: A radiation module capable of resisting reverse flow of hot fluid includes a fan, a radiator and a retaining tool. The fan provides an inlet and an outlet. The radiator is connected to the outlet of the fan. The retaining tool secures the radiator to a heat generation part. At least a baffle is provided in the radiation module. The fluid enters the fan via the inlet and flows toward the radiator via the outlet to cool the heat-generating component and the hot fluid moving outward the radiator is resisted entering the inlet with the baffle part so as to enhance heat dissipation efficiency.

Abstract: A method of accessing and processing a file stored in a sub-memory of a portable terminal including the sub-memory and an internal memory capable of storing mass storage data. The method includes storing a file system menu of the sub-memory in the internal memory during a boot-up operation, displaying the file system menu when shifting into a file access mode for the sub-memory from a waiting mode, accessing file data selected from the file system menu and buffering the file data in the buffer of the internal memory until the file data have a size corresponding to a predetermined upper limit value, processing the buffered file data, buffering data of the sub-memory in the buffer until the data have a size corresponding to the upper limit value when a quantity of buffered data becomes lower than a predetermined lower limit value while processing the buffered file data, and repeating data processing and buffering procedures until a closing command is generated.

Abstract: Disclosed is a method of controlling a mobile phone capable of processing incoming call signals, alert sounds and speech signals from a caller, comprising setting modes to be implemented in an audio signal sending mode for outputting audio signals and alert sounds to an external audio player equipped with a radio, modulating an audio signal or an alert sound generated during a mode implemented in the audio signal sending mode to a wireless signal having a predetermined frequency and sending the modulated signal or sound to the radio in the external audio player, and outputting an audio signal or an alert sound generated during a mode that is not implemented in the audio signal sending mode through a speaker of the mobile phone.

Abstract: A mobile communication terminal with a multi-input device and a method of using the same is provided. The mobile terminal performs an entry function and a search function using a multi-entry unit. The multi-entry unit includes a light-emitting sheet having a variety of colors, and being illuminated with designated colors according to character categories during a touch-entry mode for a key entry function; a sense pad for detecting a key entry signal during the touch-entry mode, and detecting a selection signal generated by rotation during the wheel mode; a transparent ground sheet for separating the sense pad from the light-emitting sheet; and an injection material in which characters displayed during the touch-entry mode are differently formed according to their categories, and the characters are illuminated with their unique colors through the light-emitting sheet so that desired characters are displayed.
