  • Publication number: 20130328542
    Abstract: A voltage generator includes a first transistor, a second transistor, an operational amplifier, a capacitor, a third transistor, a fourth transistor and a first resistor. The operational amplifier includes a first terminal coupled to a second terminal of the first transistor, and a second terminal coupled to a second terminal of the second transistor. The capacitor is coupled between an output terminal of the operational amplifier and a ground terminal. The third transistor is coupled to the first transistor and the output terminal of the operational amplifier. The fourth transistor is coupled to the second transistor, the output terminal of the operational amplifier and the ground terminal. The first resistor is utilized for generating a complementary to absolute temperature voltage according to a voltage difference between a gate-source voltage of the third transistor and a gate-source voltage of the fourth transistor.

  • Publication number: 20120273167
    Abstract: A loop heat pipe structure includes an evaporator and a first pipe. The evaporator has a first chamber, a first wick layer, and a bottom. The first wick layer is provided in the first chamber. The first pipe includes a first inlet and a first outlet communicably connected to the evaporator. The first inlet internally defines a second chamber communicable with the first wick layer. By providing the second chamber outside the evaporator, the evaporator can have a reduced overall height without creating very high vapor pressure in the evaporator, enabling the loop heat pipe structure to have upgraded heat dissipation efficiency.

  • Publication number: 20060224879
    Abstract: A method for starting an operating system rapidly by a hotkey includes the steps of: setting a hotkey for each operating system; executing a BIOS power on self test program; determining whether any hotkey has been pressed during execution of the power on self test program; activating a disk partition section which stores an operating system corresponding to a hotkey if the hotkey has been pressed; loading a master boot record; starting the operating system stored in the activated disk partition section.

  • Publication number: 20060089999
    Abstract: Various embodiments are described to provide wireless download services that are more robust than those currently available. Signaling between and among the user equipment (UE) (101) obtaining download service, one or more IMS (IP multimedia subsystem) servers (151), and the download server (161) from which the content is obtained enable an improved level of service. Some improvements that may be realized include guaranteed QoS levels for content downloads, user selection of QoS (in real-time and per content request, possibly), flexible pricing options (e.g., per session, content-based, QoS-based billing), and authentication on a per-content basis.

  • Publication number: 20060055601
    Abstract: A laminated dielectric block (3) is formed by laminating dielectric sheets (31) each having a conductive film formed on its one surface so as to constitute at least one filter (2). A radiation element (1) is provided so as to fix to the laminating dielectric block, wherein one electrode of the filter is electrically connected to the radiation element. The other electrode (22) of the filter is connected to a feeding terminal electrode (4) provided mounting face B (a face opposing to a circuit board) of the laminated dielectric block through a via-contact (33) and a wiring (34), not being exposed to the side face. As a result, an antenna with built-in filter of the structure where even if it is mounted on a circuit board, interference between an electronic circuit on the circuit board and the feeding terminal electrode of the antenna is prevented to improve the isolation characteristic and transmitting or receiving characteristic.

  • Patent number: 6917613
    Abstract: A method of delivering data and real-time media from a first mobile terminal to a second mobile terminal when the data is transferred through a packet-switched network, and the real-time media is transferred through a circuit-switched network. The real-time media is passed from the first mobile terminal to the second mobile terminal in a circuit-switched call, and the data is passed in a packet-switched data session. The second mobile terminal associates the circuit-switched call with the data session using binding information, such as an identifier of the first mobile terminal, passed to the second mobile terminal from the first mobile terminal. The real-time media and the data are then presented simultaneously to a user of the second mobile terminal.

  • Patent number: 6574469
    Abstract: A system, method and access gateway for minimizing the number of transcodings of a speech signal during a Voice-over-IP (VoIP) conference call in a packet-switched network in which Tandem Free Operation (TFO) is utilized. The system includes a first gateway connecting the first mobile subscriber to the network, a second gateway connecting the second subscriber, and a third gateway connecting the third subscriber. The second gateway sends a message to the first gateway indicating a speech coding mode being utilized between the second gateway and the second subscriber. The third gateway sends a message to the first gateway indicating a speech coding mode being utilized between the third gateway and the third subscriber. When a three-way conference call is initiated, the first gateway encodes the call path to the second subscriber with the speech coding mode being utilized between the second gateway and the second subscriber.

  • Publication number: 20020122401
    Abstract: A system and method in a wireless telecommunication network for placing on hold an ongoing circuit-switched voice call between a first party and a second party, and conducting a packet-switched data session between the second party and a third party. An enhanced Gs interface between a Serving GPRS Support Node (SGSN) in a packet-switched network and a Mobile Switching Center (MSC) in a circuit-switched network enables messages to be passed that enable the second party to place the first party on hold and either accept an incoming data session from the third party or originate a data session to the third party. When the data session is completed, the MSC is notified, and the voice call is resumed between the first party and the second party.

  • Patent number: 6421007
    Abstract: The invention provides a method and apparatus for determining the direction of a signal such as for example a received radio signal in a cellular mobile communication system. At lest two antenna arrays (10, 12) are connected to associated processors (14, 16) for extracting the desired signal and two independent direction of arrival estimates are determined in associated direction estimators (18, 20). A similarity testing unit (22) determines the direction of arrival and the accuracy of this estimate from the difference between the two estimates. A feature of the invention is controlling the beam form of a downlink signal in response to the direction estimate and the determined accuracy.
