Abstract: A portable electronic device includes a housing and a chip card holder. The chip card holder includes a base fixed to the housing, a drawer slidably fixed to the base. The drawer includes at least two stacked receiving grooves, each receiving groove receives one of the chip cards.

Abstract: A chip card holder for holding at least one chip card is disclosed. The chip card holder includes a base, a drawer slidably attached to the base and a cover. The drawer defines at least one receiving space, each receiving space for receiving a chip card. The cover is detachably latched to the base to retain the drawer in the base or allow the drawer to be slid out of the base. After the cover is detached from the base, the drawer can automatically partially or completely slide out of the cabinet to expose it from the base, thereby facilitating grasping chip cards out of the receiving spaces or putting the chip cards in the receiving spaces.

Abstract: In a method for optimizing music using an electronic device, music genres and optimization parameters of each of the music genres are preset. The method classifies songs stored in a storage device of the electronic device according to the music genres. When a song is playing using a music player of the electronic device, a music genre of the song is determined. The method further optimizes the song using an equalizer of the music player according to the optimization parameters corresponding to the determined music genre.

Abstract: In a method for switching between applications of an electronic device, a switch mode and an activation condition of the switch mode are set. The method displays a switch menu on a current user interface when the switch mode is activated, the switch menu includes icons of running applications of the electronic device. The method determines a selected icon in response to receiving a touch signal on the selected icon in the switch menu, and determines one of the running applications corresponding to the selected icon. The current user interface is switched to a software interface of the determined running application.

Abstract: In a wireless control method, functional components that can be wirelessly controlled in an electronic device are set to be remote control components. A wireless control means of each of the remote control components and functions of each of the remote control components are preset. The method determines a remote control component that is currently working in the electronic device. The method further receives a wireless control signal by the electronic device, and executes a function of the determined remote control component, when the received wireless control signal is used to perform the wireless control means of the determined remote control component.

Abstract: In a file management method of an electronic device, multi-touch operations on a touch screen of the electronic device is detected in real-time. File attributes of operating objects of the electronic device that are selected by a multi-touch operation are acquired, and a file type is determined for each of the operating objects according to the file attributes of each of the operating objects, wherein the file type is a file or a folder. The operating objects are managed according to the file type of each of the operating objects.

Abstract: A global positioning system antenna includes a radiator. The radiator includes a base section, an extension section connected to an edge of the base section, a first curved section connected to an edge of the extension section, and a second curved section connected to a distal end of the first curved section. The first curved section and the base section define a slot therebetween. The second curved section defines a first gap and a second gap thereon. The first gap and the second gap face each other.

Abstract: In a method of an electronic device for arranging icons of applications of the electronic device, a starting time and an ending time of each of the applications is recorded in a storage system of the electronic device each time that the applications are run. A number of time intervals within a day are fixed, and a sample period is set, so that if a user of the electronic device selects an applications menu displayed on a display screen of the electronic device, the icons of each of the applications are arranged in the applications menu according to the counted running time of each of the applications.

Abstract: In a method for editing text using a mobile phone, a user via a touch screen of the mobile phone selects a target text displayed on the touch screen. Handwritten data input by the user via the touch screen is recognized by a handwriting recognition system of the mobile phone. A predetermined editing operation corresponding to the handwritten data is performed on the target text. The editing operation is a cut operation, a copy operation, or a paste operation.

Abstract: An electronic device that can enable OMTP headsets and standard headsets to be compatible includes a switch unit. The switch unit includes two switches. Each of the two switches includes a moving contact and two stationary contacts. A standard headset or an OMTP headset can be applied on the electronic device by switching between the moving contact and the two stationary contacts of the two switches.

Abstract: An electronic device with antenna switch comprises a first antenna, a first proximity sensor, a second antenna, a detection module, a determination module and a control module. The first proximity sensor is located with the first antenna at a first side portion of the electronic device. The detection module detects an approach signal from the first proximity sensor. The determination module determines whether the strength of the approach signal is stronger than a threshold value in real time. The control module initiate the second antenna to receive signals through the switch if the strength of the approach signal is stronger then the strength of the threshold value.

Abstract: A wireless communication device receives a message periodically broadcast by a wireless broadcast device placed within a location, and determines a type of the location and a broadcast period of the message. The wireless communication device sets a check period for periodically checking whether the wireless communication device receives the message, and checks if a present alert mode of the wireless communication device is suitable for the type of the location in a present check period. When the present alert mode of the wireless communication device is not suitable, the wireless communication device automatically switches the present tone mode to a new tone. When the wireless communication device does not receive the message within a next check period, the wireless communication device is determined as having left the location and automatically switched back to the present alert mode from the new alert mode.
