Abstract: The invention relates to a mobile electronic device, and in particular, to a mobile electronic device with a camera ring serving as an antenna. A mobile electronic device comprises an RF module, a camera lens, and a camera ring. The RF module disposed inside of the mobile electronic device is utilized to process an RF signal. The camera ring disposed on a peripheral of the camera lens and connected with the RF module is utilized to transmit or receive the RF signal to the RF module.

Abstract: The invention utilizes an audio signal line of an earphone jack in an electronic system to charge a portable electronic device. By using an audio/charging module in the electronic system and another audio/charging module in the portable electronic device, a charging mode is established in which a first audio signal line of earphone jack carries a power signal to charge the portable electronic device.

Abstract: A series of novel phosphorus-containing cured benzoxazine resins, which are synthesized from dihydrobenzoxazine resins with reactive phosphorus-containing compounds. The cured benzoxazine resins have desired flame retardancy and high glass transition temperature, and are suitable for the fabrication of printed circuit board and the semiconductor encapsulant applications.

Abstract: A portable electronic device and a video conference system integrated with the portable electronic device are described. The video conference system has a portable electronic device, a computer, and a display. The portable electronic device generates first video data. The computer receives second video data and second voice data from a remote electronic device. The computer receives the first video data through a transmission interface. The computer has an audio-receiving device for receiving an audio signal and generating first audio data. The display receives and displays the second video data. The computer displays the second audio data and sends the first video data and the first audio data to the remote electronic device through a network transmission medium, so that a video conference is conducted.

Abstract: A portable electronic device equipped with multi-function high speed bus and the relevant method is provided in the invention. The portable electronic device includes a main electronic apparatus for connecting to an expansion device through an expansion pack. The central processing unit (CPU) of the main electronic apparatus is connected to the host controller by a first system bus. The host controller is connected to the expansion pack by a multi-function high speed bus. The first system bus is electrically connected to the CPU and includes P signal lines; the multi-function high speed bus includes Q signal lines, where Q<P. The host controller bridges the signals from P signal lines of the first system bus and the signals from the Q signal lines of the multi-function high speed bus. The host controller receives the signals from the first system bus in M clock cycles and outputs the signals to the multi-function high speed bus in N clock cycles, where N>M.

Abstract: A serial/parallel data transformer module has a first serial/parallel data transformer having a parallel port and a serial port, a second serial/parallel data transformer having a parallel port and a serial port, and a control unit for selectively connecting the parallel ports or the serial ports of the first serial/parallel data transformer and the second serial/parallel data transformer.

Abstract: A connection-converting device (300) is used to connect an expansion card (110) to a portable electronic product (20), for example, a personal digital assistant which has a circuit board (100) and a card socket (120) mounted on the board. The expansion card is implemented with an M number of signal terminals (415), and the card socket is implemented with an N number of pins (150), wherein, the number of signal terminals is greater than the number of pins. The board is provided a P number of contact pads (250) thereon, wherein P is equal to M minus N. The connection-converting device (300) has an M number of signal pins (315) electrically engaging with the signal terminals (415), an N number of receptacle terminals (335) electrically connecting with the pins (150) and a P number of external contact terminals (350) electrically connecting with the contact pads (250).
