Title: Method for converting metadata for sharing metadata
Inventor: KIM JUNG IL
IPC: G06F17/00
Filed: 2002-12-31
Abstract: PURPOSE: A method and a system for sharing metadata and exchanging data for information integration are provided to offer a consistent information exchange mechanism between diverse standards on a data level in order to realize the information integration of all systems having diverse standardization mechanisms and methodologies. CONSTITUTION: Individual standard data storages(125,165) store the data element written in a preset standard to be recognized/applied to the first or the second information system(110,150). Common standard data storages(127,167) store the standardized data element commonly applied to the information systems regardless of a sort or a construction time. Delta value extractors(130,170) extract the discordance in a meaning, a structure, and expression between the individual standard data element and the common standard data element. Converters(140,180) convert the individual standard data element into the common standard data element. Transceivers(145,185) transceive the common standard data element converted in the converters with the information systems.

Title: Bulk accoustic wave filter
IPC: H03H9/58
Filed: 2001-06-07
Abstract: A ladder filter comprises series and shunt resonators (2, 4). The or each shunt resonator (4) has a static capacitance which is more than four times the static capacitance of the input or output series resonators (2i, 2o). This provides increased shunt resonator capacitance which reduces the effective coupling across the a series-shunt section, thereby enabling a smaller number of series-shunt filter sections to used to achieve good stop-band rejection, while still providing good performance in the pass-band. The invention is based on the recognition that filter bandwidth can be traded for improved out-of-band rejection.
