20100268610 | ONLINE ADVERTISING METHOD AND ONLINE ADVERTISING SYSTEM - The present invention relates to an online advertising method and an online advertising system, and more particularly, relates to an online advertising method and an online advertising system using a knowledge providing service system which enables knowledge to be provided through questions and answers between users. | 10-21-2010 |
20100306051 | SYSTEM AND METHOD FOR SELECTING SEARCH LISTING IN AN INTERNET SEARCH ENGINE AND ORDERING THE SEARCH LISTINGS - Provided is a keyword advertising system for extracting search listings in response to a search request. The system comprises a memory for storing a search information database; a bid control module selecting a predetermined number of search listings primarily according to the bid amount and an estimated advertising period; a ranking module generating an ordered search result list; and a computation control module computing the advertising period for the received bids. The ranking module orders the selected search listings in the search result list according to the selected search listings' respective bid amounts and the estimated advertising period and the computation control module estimating advertising costs uses the bid amount of the advertiser and average number of clicks information during a predetermined previous period. The computation control module further calculates the estimated advertising period using deposit from the advertiser and the estimated advertising costs. The search information database stores at least one bid received from advertisers, the at least one bid being associated with a cost per click advertising, the each bid being associated with a keyword, a bid amount and a search listing. | 12-02-2010 |

20090003128 | Method of Acquiring an Ultrasound Image - The present invention relates to a method of acquiring an ultrasound image in an ultrasound imaging system having an array transducer, comprising: a) setting an image point at a predetermined depth on an ultrasound image acquired based on a reference speed of sound for a target object; b) setting a range of speed of sound with reference to the reference speed; c) setting a plurality of speeds of sound in a predetermined interval within the range of speed of sound; d) acquiring ultrasound images at each speed of sound; e) calculating an amplitude of an image point set at a predetermined depth of each ultrasound image; f) determining a real speed of sound in the target object based on the calculated amplitude; and g) acquiring an ultrasound image based on the determined real speed of sound in the target object. | 01-01-2009 |
20090112093 | ULTRASOUND DIAGNOSTIC DEVICE AND METHOD FOR FORMING SCAN LINE DATA - There is provided an ultrasound diagnostic device including receiving data a transmission lines between scan line data forming units and channels and a method of forming scan line data. The ultrasound diagnostic device includes a plurality of channels for providing receiving data and a scan line data forming unit including a plurality of sub-scan line data forming groups and a data summing unit, wherein the sub-scan line data forming group forms partial data of scan lines, and wherein the data summing unit forms scan line data of the scan lines by summing the partial data. The sub-scan line data forming group includes a plurality of sub-scan line data forming units for forming the partial data of the scan lines by using the receiving data and providing a transmission path of the receiving data, first data lines for transmitting the receiving data between at least one of the sub-scan data forming unit and the channels and second data lines for transferring the receiving data between the sub-scan line data forming units. | 04-30-2009 |
20090131797 | Ultrasound Diagnostic Device Having Transducers Facing Each Other - The present invention relates to an ultrasound diagnostic device. The ultrasound diagnostic device comprises a pair of transducers operable to transmit/receive ultrasound signals. The transducers are arranged to face each other. The transducers may be an array transducer including a plurality of elements, which are linearly arranged. | 05-21-2009 |
20090137903 | Transmit Apodization Using A Sinc Function In An Ultrasound System - The present invention relates to transmit apodization using a sinc function in an ultrasound system. The ultrasound system includes: a transmission unit operable to generate transmit pulse signals with transmit apodization applied by using a sinc function; a probe operable to generate ultrasound signals based on the transmit pulse signals to thereby form a transmit beam and transmit the transmit beam along a predetermined scan line among a plurality of scan lines in a target object, the probe being further operable to receive ultrasound echoes reflected from the target object; and a reception unit operable to form receive signals corresponding to a plurality of scan lines based on the ultrasound echoes. | 05-28-2009 |
20090318811 | ULTRA SOUND SYSTEM FOR FORMING STRAIN IMAGES WITH INSTANTANEOUS FREQUENCY - There is provided an ultrasound system for forming strain images by decreasing decorrelation of receive signals, which vary with time or space. More specifically, the decorrelation between the receive signals obtained without and with applying stress to a target object is reduced to decrease an error, which occurs during the calculation of a delay. Also, a center frequency, which varies with depth of a target object, is compensated to form the strain image. | 12-24-2009 |
20090326378 | Formation Of An Enhanced Elastic Image In An Ultrasound System - There are disclosed embodiments for forming an enhanced elastic image in an ultrasound system. An elastic image of a target object may be formed by scanning N scan lines. A control unit divides the N scan lines into M scan lines groups by using an acquisition period necessary for transmitting and receiving ultrasound signals to acquire ultrasound data. An ultrasound data acquiring unit transmits ultrasound signals to a target object and receives the ultrasound signals reflected from the target object at a predetermined transmission/reception sequence for each of the M scan line groups. This forms ultrasound data corresponding to each of the M scan line groups while a pressure is applied to the target object. An elastic image forming unit forms at least one sub elastic image corresponding to each of the M scan line groups based on the ultrasound data. The elastic forming unit sums M sub elastic images corresponding to the respective M scan line groups to thereby form an elastic image of the target object. | 12-31-2009 |
