Abstract:
An antenna structure is configured to transmit and receive signal for a wireless communication device. The antenna structure includes a base board, a radiating unit, and a feed unit. The radiating unit and the feed unit are formed on the base board. The feed unit partially overlaps on the radiating unit to form a number of signal feed paths.
Abstract:
An exemplary earphone detecting circuit includes a signal input terminal, a voltage dividing circuit, a detecting circuit, and a signal output terminal connected electronically in that order. The signal input terminal is connected to an earphone jack of a portable electronic device. The signal output terminal is connected to a microcontroller of the portable electronic device. When the portable electronic device receives a call, the signal input terminal receives a signal and transmits the received signal to the detecting circuit through the voltage dividing circuit, the detecting circuit processes the signal transmitted to the signal output terminal to be constant.
Abstract:
A wire arrangement structure includes a first fixed rod, a second fixed rod, a movable rod, a wire, and an elastic member. The elastic member is connected to the movable rod. When the second fixed rod slides relative to the first fixed rod, the elastic member provides a force to move the movable rod to adjust the length of the wire.
Abstract:
In a method for selecting objects of an electronic device, a touch operation performed on a touch screen of the electronic device is detected. A selection region on the touch screen is determined according to a touch operation that is detected from the touch screen. The selection region is scaled according to one or more predetermined ratios when contact points of the touch operation move on the touch screen. Objects displayed on the touch screen are selected according to the determined selection region.
Abstract:
A wireless communication device includes a body, an antenna, a first baseband microchip, a second baseband microchip, and a diplexer. The antenna is telescopically assembled to the body to receive a first wireless signal and a second wireless signal. The diplexer is electronically connected to the antenna, the first baseband microchip, and the second baseband microchip. When the antenna is in a retracted state, the antenna receives the first wireless signal, and the diplexer transmits the first wireless signal to the first baseband microchip. When the antenna is in an extended state, the antenna receives the second wireless signal, and the diplexer transmits the second wireless signal to the second baseband microchip.
Abstract:
A multifunctional case is configured for receiving or supporting a portable electronic device. The case includes a first layer and a second layer. The second layer is connected to the first layer by the edges. A receiving space is formed between the first and second layers for receiving the portable electronic device. The second layer is provided with a base portion, a main supporting portion, two side supporting portions and two remaining portions are formed on the second layer. The two side supporting portions and the remaining portions are symmetrically positioned at two sides of the main supporting portion. When the case is folded up as a support, the main supporting portion is angled with the base portion. The remaining portions are stacked on the base portion. The side supporting portions are perpendicular to the remaining portions and the main supporting portion.
Abstract:
A method for managing an electronic phone book is used in a communication device which includes a universal subscriber identity module (USIM), a system for executing the method, a storage device, and a processor. The USIM includes elementary files. The system and the method identify information updated by users for saving the electronic phone book, a contact name, a contact phone number, and a contact email address according to link information of each elementary file. The system and the method update the contact information of USIM according to the information updated by the users. The contact information of USIM can be quickly updated by utilizing the method and the system.
Abstract:
In a near-field communication (NFC) service protection method of the mobile device, the mobile device includes an NFC controller, one or more security elements, a global positioning system (GPS) and a storage system. The method sets a security code for an NFC service of each of the security elements according to the geographic location of the mobile device as acquired by the GPS, and stores a security protection of the NFC service corresponding to each of the NFC services into the storage system. After an NFC service is selected from one of the security elements, and the NFC service is performed by executing an NFC application corresponding to the NFC service through the NFC controller. In addition, the method deletes the security code of the NFC service to disable the security protection of the NFC service when the NFC service needs to disable the security protection.
