    Abstract: A method for producing hydrogen includes providing a feed stream comprising water; contacting at least one proton conducting membrane adapted to interact with the feed stream; splitting the water into hydrogen and oxygen at a predetermined temperature; and separating the hydrogen from the oxygen. Preferably the proton conducting membrane comprises a proton conductor and a second phase material. Preferable proton conductors suitable for use in a proton conducting membrane include a lanthanide element, a Group VIA element and a Group IA or Group IIA element such as barium, strontium, or combinations of these elements. More preferred proton conductors include yttrium. Preferable second phase materials include platinum, palladium, nickel, cobalt, chromium, manganese, vanadium, silver, gold, copper, rhodium, ruthenium, niobium, zirconium, tantalum, and combinations of these. More preferably second phase materials suitable for use in a proton conducting membrane include nickel, palladium, and combinations of these. The method for generating hydrogen is preferably preformed in the range between about 600° C. and 1,700° C.

    Abstract: A surround signal processing apparatus and method can realize sound image localization and have reverberation effects. In the apparatus, left and right impulse measuring sections measure left and right impulses of a head related transfer function for an input audio signal based on a number of a plurality of lattices defined in a three dimensional space, horizontal and vertical angles defined by a center of a dummy head and the plurality of lattices. Left and right convolution operators convolve left and right channel signals of input audio signal with left and right impulses of head related transfer function, respectively, in order to localize sound image for input audio signal at an objective localization position. Left and right reverberators impart first and second reverberant sounds to left and right channel signals, respectively. According to the apparatus and method, it is possible to reproduce two pseudo surround signals from a pair of virtual rear speakers by use of a pair of actual front speakers; that is, to construct a 4-channel surround system by use of only two speakers. Further, they provides a listener with a feeling of presence as if he is listening to the music in a different sound field such as a spacious concert hall, church or stadium notwithstanding the fact that he is actually in an ordinary room, a listening room, or a vehicle.
