Encoding device and decoding device

Abstract: An encoding device (200) includes an MDCT unit (202) that transforms an input signal in a time domain into a frequency spectrum including a lower frequency spectrum, a BWE encoding unit (204) that generates extension data which specifies a higher frequency spectrum at a higher frequency than the lower frequency spectrum, and an encoded data stream generating unit (205) that encodes to output the lower frequency spectrum obtained by the MDCT unit (202) and the extension data obtained by the BWE encoding unit (204). The BWE encoding unit (204) generates as the extension data (i) a first parameter which specifies a lower subband which is to be copied as the higher frequency spectrum from among a plurality of the lower subbands which form the lower frequency spectrum obtained by the MDCT unit (202) and (ii) a second parameter which specifies a gain of the lower subband after being copied.

From local structure to nanosecond recrystallization dynamics in AgInSbTe phase-change materials

Abstract: Phase-change materials are key components in rewritable optical disks and are promising for non-volatile electronic memories. The very different structure and ultrafast recrystallization dynamics of another class of phase-change materials, Sb–Te-based alloys, now suggests their use in future memory applications.

Power-line carrier communication apparatus

Abstract: The invention provides a power-line carrier communication apparatus including a transmission unit with a signal point mapping device for mapping a plurality of bit streams produced from transmission data, a wavelet inverse transforming device for modulating the respective sub-carriers by wavelet waveforms which are orthogonal to each other for producing temporal waveform series data, and a D/A converter for converting the temporal waveform series data into an analog temporal waveform series signal; and a reception unit with an A/D converter for obtaining sampling-series waveform data from a power-line communication signal, a wavelet transforming device for wavelet-transforming the sampling-series waveform data into signal point data of the respective sub-carriers, and a symbol judging device for judging bit streams mapped by the signal point mapping device by inverse-mapping a plurality of these signal point data, and for synthesizing the judged bit streams with each other as a reception data series.

Parking assistance system

Abstract: A parking assistance system is mounted in a vehicle, and has an image pick-up with a single camera, an image processing device, a display, a steering angle sensor, a wheel speed sensor, and a pulse counter. An A/D converter subjects two analog images picked up by the image pick-up at different locations to A/D conversion, and sends the results to frame memories. A CPU uses the digital image data and the transition data of the vehicle to calculate object data and a distance from the vehicle to the 3D object. An image thus obtained is then converted into a view from the above. The view from the above is stored in a frame memory, and outputted to the display under the control of a controller for display.

Peer-to-peer (P2P) connection despite network address translators (NATs) at both ends

Abstract: Methods of operating a first endpoint device (ED) facilitate the making of a peer-to-peer (P2P) connection between the first ED and a second ED despite intervening network address translators (NATs) at both ends. The P2P connection extends across a system compliant with the internet protocol (IP) whose architecture that includes a first network (having at least the first ED and a first NAT), a second network (having at least the second ED and a second NAT) and a third network. The first ED connects to the third network via the first NAT while the second ED connects to the third network via the second NAT. A first such method includes: providing the second ED with the first IP-address/port pair; and providing the second ED with first type-information regarding the type of the first NAT.
