| 20100202633 | SOUND SYSTEM, SOUND REPRODUCING APPARATUS, SOUND REPRODUCING METHOD, MONITOR WITH SPEAKERS, MOBILE PHONE WITH SPEAKERS - The present invention relates to an apparatus for reproducing sound, a method for reproducing sound, a monitor with speakers, and a mobile phone with speakers. An apparatus according to the present invention is an apparatus for reproducing sound from original source signals, and comprises a control means, a first speaker, and a second speaker. The control means receives first and second original source signals, and controls magnitudes and phases of the received first and second original source signals so that a sound pressure level in a pre-determined zone is higher than a sound pressure level in zone other than the pre-determined zone, and outputs first and second controlled source signals. The first speaker receives the first controlled source signal and reproduces sound. The second speaker receives the second controlled source signal and reproduces sound. The apparatus according to the present invention can provide the sound environment in which only the person using the sound system enjoys the sound. | 08-12-2010 |

| 20110090507 | APPARATUS FOR DETECTING FOREIGN MATERIAL IN POUCH TYPE BATTERY - An apparatus and method for detecting a foreign material within a pouch type battery by performing a light scattering method on a surface of a battery case are provided. The apparatus for detecting a foreign material within a pouch type battery includes: a light source irradiating linear light to a surface of a battery case at a pre-set incident angle; a sensor unit sensing light reflected from the battery case; and a foreign material detection unit detecting the presence or absence of a foreign material and the position of the foreign material within a battery through the reflected light sensed by the sensing unit. A foreign material within a battery can to be quickly and accurately detected. | 04-21-2011 |
| 20110123399 | DEVICE FOR MEASURING PROTEINS USING BIOSENSOR - A sensor for measuring a protein with a measurement speed improved from a conventional impedance measurement, using a biosensor is provided. The sensor is capable of efficiently and accurately measuring impedance generated by a selective binding to the protein by Fourier-transforming an electric current signal which is obtained by applying a potential signal of a delta function waveform. | 05-26-2011 |
| 20110136215 | APPARATUS FOR STIMULATING CELL - An apparatus for stimulating cell includes a cell culture chamber, a control device, and first and second exciters. The cell culture chamber includes cell and culture medium. The control device receives first and second exciting signals, and controls magnitudes and phases of the received first and second exciting signals so that a sound pressure level in a focused zone is higher than a sound pressure level in a zone other than the focused zone, and outputs first and second controlled exciting signals. The first and second exciters receive the first and second controlled exciting signals and excite the cell culture chamber. | 06-09-2011 |

| 20090093243 | RADIO LINK PARAMETER UPDATING METHOD IN MOBILE COMMUNICATION SYSTEM - A radio link (RL) parameter updating method of a high speed downlink packet access (HSDPA) system in a mobile communication system is disclosed. According to a radio channel situation of a terminal, an RL parameter applied to transmission and reception of control information between the terminal and a base station is dynamically controlled. For this purpose, the RL parameter updating method includes: a step in which the base station determines whether to update an HSDPA related parameter and transmits the parameter update information to the RNC to trigger updating of the RL parameter; and a step in which the RNC updates the HSDPA related parameter and transmits it to the terminal. The parameter update information is delivered through an RL parameter update response message, and the RNC is a serving RNC. | 04-09-2009 |
