| 20110275930 | SYSTEMS AND METHODS FOR IDENTIFYING AND LOCATING AN IMPLANTED DEVICE - A system for identifying an attribute of an implanted medical device, such as an access port is disclosed. In one embodiment, the identification system comprises a marker included with the implanted medical device, wherein the marker relates to an attribute of the implanted medical device. An external detection device is also included, comprising a signal source that emits an incident electromagnetic signal for impingement on the marker of the implanted medical device, a detector that detects a return signal from the marker resulting from impingement of the incident electromagnetic signal, and a user interface for conveying information relating to the attribute based on detection of the return signal. In the case of an implantable access port, for instance, the described system enables information, such as the ability of the port to withstand power injection of fluids therethrough, to be ascertained even after the port has been subcutaneously implanted within the patient. | 11-10-2011 |

| 20100076352 | APPARATUS USING FOCUSED ULTRASOUND WAVE BY CONTROLLING ELECTRONIC SIGNALS AND USING METHOD THEREOF - The present invention relates to an extracorporeal High Intensity Focused Ultrasound (HIFU) necrosis apparatus through the control of an electronic signal, including oscillation elements for generating ultrasonic beams, an ultrasonic oscillator array having the oscillation elements fixed on a plane and oriented toward a life, delay circuits respectively connected to the oscillation elements for delaying ultrasonic oscillation by a delay time, and control means for controlling the delay time so that the ultrasonic beams are focused, and a method of employing the same. According to the present invention, waved surfaces with a variety of directions and curvatures can be formed using several oscillation elements and several delay circuits disposed on a plane, and a focus can be formed at any desired place. Accordingly, there are advantages in that installation is convenient, and a tissue, such as tumor, which is a target tissue, can be necrotized without damage to normal tissues necrosis. Further, there is no damage to normal tissues other than a target tissue. Accordingly, there are advantages in that a recovery speed of a patient can quicken, a symptom after recovery can be mitigated, and so on. | 03-25-2010 |

| 20090154711 | MULTI-PARTY KEY AGREEMENT METHOD USING BILINEAR MAP AND SYSTEM THEREFOR - The present invention provides an efficient method and system in which a plurality of participants share a secret key in a communication environment that is not ensured. According to an embodiment of the invention, each of the participants is assigned with a secret key from a key generation party, generates exchange information, and transmits its own exchange information to the other participant to exchange the exchange information with each other. Each of the participants generates a shared key on the basis of the exchange information and its own secret key. | 06-18-2009 |
| 20100138399 | METHOD FOR DATA ENCRYPTION AND METHOD FOR DATA SEARCH USING CONJUNCTIVE KEYWORD - The present invention relates to a method for data encryption and a method for data search using a conjunctive keyword and more particularly to, a method for searching data stored in a server by using a conjunctive keyword after storing an index table for the conjunctive keyword and encrypted data in the server. According to an embodiment of the present invention, since keywords and relevant data do not need to be searched one by one by performing a conjunctive keyword search by using a linked tree structure modifying a linked list, it is possible to perform a rapid and efficient conjunctive keyword search. | 06-03-2010 |
| 20100153403 | METHOD FOR DATA ENCRYPTION AND METHOD FOR CONJUNCTIVE KEYWORD SEARCH OF ENCRYPTED DATA - A server provides the user's desired data without the server knowing the contents or keywords of data by using a method of searching the desired data without decrypting the encrypted data, such that the privacy for the important data of the user can be secured. Also, the present invention shortens the operation time when searching the encrypted data, such that it can prevent the degradation in efficiency due to excess operation involved in the previous existing methods based on the pairing operation. | 06-17-2010 |
