  • Patent number: 9854540
    Abstract: A mobile communication device and a radiated power adjusting method thereof are provided. The mobile communication device includes an antenna, a signal measurement module, a proximity sensing module and a controlling module. The antenna receives a radio-frequency signal, and the signal measurement module is coupled to the antenna and measures a signal parameter of the radio-frequency signal. The proximity sensing module is switched between an activation mode and an original detection mode according to existence of an object, wherein a sensing conductor is configured adjacent to an adjusted antenna. The controlling module is coupled to the signal measurement module and the proximity sensing module, and the controlling module adjusts the radiated power of the adjusted antenna. When the signal parameter decreases more than a threshold value and the proximity sensing module is in the activation mode, the controlling module reduces the radiated power of the adjusted antenna.

  • Patent number: 9575654
    Abstract: A touch device and a control method thereof are provided. In the control method, a sensing signal generated by a sensor is received. When an operating object is present, a touch screen is configured for touchable regions and untouchable regions, wherein the untouchable regions cannot generate a response through a touch by the operating object. A gesture is received on the untouchable regions of the touch screen, a processor determines whether the gesture is conformed to a default gesture setting, and the processor decides whether or not to adjust part or all of the untouchable regions to the touchable regions according to the determining result. Accordingly, the touch device and the control method thereof of the embodiments of the invention can prevent or lower the occurrence of an accidental touch by a user and enhance the operating convenience of the user.

  • Patent number: 8777637
    Abstract: A connector for connecting a coaxial cable and a circuit board is disclosed. The connector includes a main body, a first holding portion, a second holding portion and a fixing structure. The first holding portion extends from a first end portion of the main body for holding a first insulation layer of the coaxial cable. The second holding portion extends from the main body in a position located between a second end portion opposite to the first end portion and the first holding portion for holding a braid layer of the coaxial cable. The fixing structure extends from the second end portion of the main body in a direction away from the second holding portion for disposing through at least one hole on the circuit board, so as to fix the coaxial cable on the circuit board.

  • Patent number: 8269678
    Abstract: An antenna module for a tablet personal computer is disclosed. The tablet personal computer comprises a main body and a housing with a screen, and the housing is pivotally connected to the main body. The tablet personal computer is capable of being switched to a tablet mode. The antenna module comprises an antenna device, a first magnetic element, and a second magnetic element. The antenna device is located concealably in the housing. The first magnetic element is coupled to an end of the antenna device. The second magnetic element is located in the main body. The second magnetic element is positioned corresponding to the first magnetic element in the tablet mode such that an end of the antenna device can be moved outside the housing due to a magnetic force between the first magnetic element and the second magnetic element.

  • Publication number: 20100188295
    Abstract: An antenna module for wireless signal transmission of an electronic device is disclosed. The antenna module comprises a main body and a feed point. The main body is a rectangular metal sheet and comprises a hollow portion. The hollow portion extends inwardly from one side of the main body. The main body may be separated by the hollow portion to form a first radiating portion, a second radiating portion, and a third radiating portion. The feed point is connected to a feed line, and is used for feeding an electrical signal to the main body, such that the first radiating portion forms a first current path, the second radiating portion forms a second current path, and the third radiating portion combined with the second radiating portion forms a third current path so as to generate different operating bands.
