20090156039 | STRUCTURE OF POWER TERMINAL FOR ABS CONNECTOR - The present invention features a power terminal for ABS connector. Preferably, the power terminal for ABS connector is inserted into and secured to an insertion pipe of a male connector for an ABS and has a conductive terminal body. The conductive terminal body has, at one end thereof, a mounting element for mounting a first waterproofing member and a first barrel for securing a power wire, guide projections, projectedly formed at a middle portion thereof, for guiding insertion of the conductive terminal body, and, at the other end thereof, a hook for maintaining an inserted state of the conductive terminal body using an elastic property thereof. The portion of the conductive terminal body that is positioned between the guide projections and the hook is lengthened, a second waterproofing member is mounted to the portion, and a second barrel for securing one end of the second waterproofing member is formed on the conductive terminal body. | 06-18-2009 |

20130147835 | TECHNIQUE FOR LOCALIZING SOUND SOURCE - 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. | 06-13-2013 |
