    摘要: Disclosed is a technique for localizing a sound source. In the technique, a sound pressure signal measured by microphones is acquired using a spherical microphone array sensor where the microphones are fixedly arranged on a surface of a spherical body. A sound pressure distribution on the surface of the spherical body is obtained by a controller from a sound pressure calculation formula for calculating a sound pressure at a certain location of a spherical surface using the sound pressure signal measured by the microphones as an input value. A location of the sound source is estimated from the obtained sound pressure distribution.

    摘要: The present invention relates to a method for synthesizing highly dispersed supported platinum catalyst. More particularly, the present invention relates to a method of synthesizing highly dispersed supported platinum catalyst comprising: dissolving a reducing agent in a solvent to produce a solution, dissolving a platinum chloride to the same solvent; adding a carbon support and platinum in a predetermined ratio to the above mixed solution, agitating the mixture, performing ultrasonic treatment, and performing heat treatment; and adding a HCl solution, agitating the mixture, separating the precipitates via filtration to produce a catalyst, and then washing the catalyst with distilled water, thereby obtaining an active highly dispersed supported platinum catalyst which has excellent electric charge activity, uniformly-sized platinum particles and relatively high specific surface area.

    摘要: An apparatus and method for controlling an audio/video (AV) device. A first AV device is adapted to receive a remote control signal, selectively modulate the received remote control signal, and transfer the modulated remote control signal along with an audio signal over an audio line. A second AV device is adapted to receive the modulated remote control signal transferred along with the audio signal over the audio line, separate the received remote control signal from the received audio signal, demodulate the separated remote control signal, and perform an operation corresponding to the demodulated remote control signal. Therefore, it is possible to normally control an AV device even though a user involuntarily operates a remote controller of the AV device toward the screen of a TV under the condition that the AV device is placed far from the TV or the angle defined by the TV, user and AV device is large.

    摘要: The present invention provides an apparatus for effectively preventing carbon corrosion from occurring at the cathode of a fuel cell. The present apparatuses include an air blower supplying air from an air supply source to a fuel cell; a fuel cell receiving air from the air blower to generate electricity by a chemical reaction; an air discharge pipe through which residual air remaining after oxygen of the air is consumed for chemical reaction in the fuel cell is discharged; a pressure sensor provided in the air discharge pipe for detecting air pressure in the fuel cell; an air discharge solenoid valve provided in the air discharge pipe for controlling air flow of the air discharge pipe; and a controller controlling operation of the air blower and the air discharge solenoid valve by receiving a signal detected by the pressure sensor wherein the controller detects the air pressure through the pressure sensor to allow the air blower to supply air to the fuel cell until the air pressure reaches a predetermined pressure and then closes the air discharge solenoid valve until the oxygen in the fuel cell is completely exhausted, thereby preventing the formation of hydrogen/oxygen interface at the anode of the fuel cell.
