  • Publication number: 20120143463
    Abstract: A method for improving startability of a of a gasoline direct injection (GDI) engine by controlling an electric continuously variable valve timing (CVVT) may include determining whether the engine is running, calculating the phase angle of the camshaft and the difference between the position of the camshaft and the optimum position of the lobe of the high pressure pump, applying a duty to the drive motor to rotate the camshaft, calculating the difference between the current position of the camshaft after rotation and the target position of the camshaft, and comparing the difference with a predetermined value. When the difference is not smaller than a predetermined value, the duty is raised and applied to the drive motor to rotate the camshaft further until the difference is reduced and smaller than the predetermined value.

  • Patent number: 8121099
    Abstract: A voice over Internet protocol (VoIP) system. The system includes a first device and a second device. The first device is disposed in a wireless local area network (WLAN) and connected to an Internet, for performing voice communication with a remote device through the Internet. Additionally, the first device processes audio information received during the voice communication to generate at least a playback audio packet, sends out the playback audio packet through the WLAN, receives at least a captured audio packet through the WLAN, and processes the captured audio packet to generate audio information to be sent out during the voice communication. The second device is disposed in the WLAN, for receiving the playback audio packet through the WLAN, playing audio information contained in the playback audio packet, capturing outside audio information to generate the captured audio packet, and sending out the captured audio packet through the WLAN.

  • Publication number: 20110181284
    Abstract: A method based on pure phase encode FIDs that permits high strength gradient measurement is disclosed. A small doped water phantom (1˜3 mm droplet, T1, T2, T2*<100 ?s) within a microprobe is excited by a series of closely spaced broad-band RF pulses each followed by single FID point acquisition. Two trial gradient waveforms illustrate the technique, neither of which could be measured by the conventional microprobe measurement. The first is an extended duration gradient waveform while the other illustrates this method's ability to measure gradient waveforms with large net area and/or high amplitude. This method is a point monitor with simple implementation and low cost hardware requirements.

  • Publication number: 20110137908
    Abstract: Techniques are described for assigning, to target categories of a target scheme, items that have been obtained from a plurality of sources. In situations in which one or more of the sources has organized its information according to a source scheme that differs from the target scheme, the assignment may be based, in part, on an estimate of the probability that items from a particular source category should be assigned to a particular target category. Such probability estimates may be based on how many training set items associated with the particular source category have been assigned to the particular target category. Source categories may be grouped into clusters. The probability estimates may also be based on how many training set items within the cluster to which the particular source category has been mapped, have been assigned the particular target category.

  • Patent number: 7732770
    Abstract: Aspects described herein provide for the design and fabrication of a device with an enhanced pyroelectric response signal comprised of multi-capacitors that are connected in series. These capacitors are fabricated using multi-layers of materials such as lead zirconate titanate (PZT), BaxSr1-xTiO3 (barium strontium titanate) and Bi4Ti3O12 (bismuth titanate) films that exhibit pyroelectric affect and belong to the class of polar materials. By controlling the poling direction of the multi-layer integrated structure, the pyroelectric voltage can be aligned in one direction, and as a result, the voltage output from the single element is the total contribution from each capacitor.

  • Publication number: 20090044055
    Abstract: A method for guiding to solve system errors is applied to a computer system. The method of the invention includes the step of calling a debugging application software to check a system state of the computer system when a request for detecting errors inputted by a user is received. When a system error occurring in the computer system is detected, a client database is connected to determine whether a corresponding solution for the user to debug the computer system exists. When the solution corresponding to the system error is not searched out from the client database, a network is connected to transfer a detected error message to a client service terminal.

  • Publication number: 20090036099
    Abstract: A content providing method and system are disclosed that enable content producers to make a profit by providing contents encrypted by a mobile terminal. The content providing method includes: encrypting, by a mobile terminal, a content and registering the encrypted content in a content providing server; finding, by a communication terminal, the content registered in the content providing server and paying a use fee to use the content; and transmitting a valid authentication key associated with the content to the communication terminal after the payment. Accordingly, since content producers directly encrypt their contents, they can make a profit corresponding to the use of the contents.
