Abstract:
Disclosed herein is an electric generating system using a solar cell, including: a DC/DC converter that converts output voltage generated from a solar cell into DC voltage and has a converter switching device; a snubber device that has a snubber switch clamping voltage applied to the converter switching device; and a control device that detects the voltage applied to the converter switching device and controls an operation of the snubber switch according to a detected voltage level applied to the converter switching device, thereby increasing the efficiency of the electric generating system using a solar cell while reducing switching loss and conduction loss.
Abstract:
The present invention relates to a method for writing a newly recognized image. The method includes the steps of: (a) comparing pre-stored image in the image database with a queried image; (b) storing the queried image onto a database for unrecognized images if there is no image similar to the queried image; (c) grouping the images in the database for unrecognized images based on degrees of similarity thereamong; and (d) comparing, if a specific image and its tag information are inputted, the specific image with some images included in a specific set of images among the organized sets of the images, determining whether there is any image in the specific set of images which has a degree of similarity exceeding the pre-set value and allowing images determined to have degrees of similarity exceeding the pre-set value with the tag information to be automatically written onto the image database.
Abstract:
A device and method for transmitting data can conveniently perform data transmission between two portable terminals. The device preferably includes a first portable terminal transmitting data on which a drag operation has occurred to a second portable terminal when the second portable terminal is coupled to the first portable terminal using a time and a moving speed of the drag operation when the drag operation occurs from the first terminal to the second portable terminal. The second portable terminal receives the data from the first portable terminal using the time and the moving speed of the drag operation when the drag operation occurs from the first portable terminal to the second portable terminal coupled to the first portable terminal through near field communication.
Abstract:
The present invention relates to a method for providing information on an object by using viewing frustums. The method includes the steps of: (a) specifying at least two viewing frustums whose vertexes are visual points of respective user terminals; and (b) calculating a degree of interest in the object by referring to the object commonly included in both a first viewing frustum whose vertex is a visual point of a first user terminal and a second one whose vertex is a visual point of a second user terminal.
Abstract:
A Second Generation Digital Video Broadcasting via Satellite (DVB-S2) system is provided. More particularly, a method and apparatus for maintaining synchronization of a signal by changing an Adaptive Coding and Modulation (ACM) method that is used for a conventional DVB-S2 system are provided. In the apparatus and method, an FEC frame of a variable length is formed by turbo encoding rather than Bose-Chaudhuri-Hocquenghem (BCH) and Low Density Parity Check (LDPC) encoding, and a Physical Layer (PL) frame of a specific length is formed regardless of a modulation method, so that a satellite terminal receives a signal transmitted at a specific length regardless of a modulation method or a coding rate to easily maintain synchronization without interruption and efficiently transmit the signal.
Abstract:
Provided are a heat radiating substrate and a method of manufacturing the same. The heat radiating substrate includes a substrate having a via-hole, an anode oxide layer formed on the entire surface of the substrate having the via-hole through an anodizing process, a first circuit pattern formed on the substrate on which the anode oxide layer is formed, and a second circuit pattern formed at a lower part of the via-hole to be connected to the via-hole. Therefore, it is possible to simplify a circuit forming process and readily manufacture the heat radiating substrate by applying a metal anodic bonding process, without using a conventional adhesion layer and metal seed when the heat radiating substrate is manufactured.
Abstract:
The present invention relates to a method for performing an image matching process for panoramic images. The method includes the steps of: (a) creating a connection(s) among images of a specific object respectively included in at least two panoramic images, if some objects included in the at least two panoramic images are recognized as the specific object by referring to information on shooting places of multiple panoramic images and information on directions of respective objects on the multiple panoramic images; and (b) matching an image of a certain object inputted as a query with at least one of images included in a specific connection and providing a search result for the query by referring to a result of the image matching process and the specific connection.
