Audio data structure for lossy and lossless encoded extension data
Lossless audio coding performs decorrelation and encodes the transformed signal. The encoded bit stream comprises de-correlation parameters and the lossless representation data of the transformed signal. However, in the case of lossy based lossless coding, the additional amount of information exceeds the base layer amount of data. Therefore the additional data cannot be packed completely into the base layer e.g. as ancillary data. The data streams resulting from the combination of lossy coding format with a lossless coding extension are the base layer containing the lossy coding information and the enhancement data stream for rebuilding the mathematically lossless original input signal. Every higher layer depends on the lower layers and can only be reasonably decoded in combination with these lower layers. According to the invention, a special combination of one-time header information with repeated header information in a block structure is used. Assignment information data identify the different layers. |

The identified locations within a presentation stream may be utilized to identify boundaries of segments within the presentation stream, such as segments of a show and interstitials of the show. Processing is then performed to determine whether the identified boundaries possess specific characteristics. If the identified boundaries do not possess the identified characteristics, then additional processing is performed to identify other locations, temporally near the identified boundaries, which correspond with boundaries of the portion of the audio/video stream identified by the autonomous location information. |

Auto exposure techniques for variable lighting conditions
Systems, methods, and a computer readable medium for performing auto exposure (AE) techniques that are beneficial in variable lighting conditions—and particularly applicable to handheld and/or mobile videoconferencing applications—are disclosed herein. Handheld and/or mobile videoconferencing applications—unlike their fixed camera counterparts—are often exposed to a wide variety of rapidly changing lighting and scene conditions, and thus face a difficult trade-off between adjusting exposure parameter values too frequently or not frequently enough.

Mobility between access domains in an Internet Protocol (IP) network can be supported by introducing a so-called Mobility Manager (MM) that maintains a database of currently attached devices and their current access domain location.

Sliding hinge and a portable electronic device with the same
A sliding hinge is mounted between a cover and a body of an electronic device and has a bracket, a linking panel, a slide and a connecting wire. The bracket is attached securely to the cover. The linking panel is attached securely to the body and is mounted slidably on the bracket. The slide is mounted slidably on the bracket. The connecting wire is wound around a fulcrum of the bracket and respectively connects to the linking panel and the slide. The cable of the electronic device is mounted through the slide. When the cover slides relative to the body, the slide and the linking panel relatively move in opposite directions. Therefore, the cable is folded to keep taut. |

Laminated ceramic electronic component and method for manufacturing the same
A plurality of ceramic green sheets having printed strip inner electrodes patterns, each including a thick portion at a width-direction center and thin portions at respective width-direction sides of the thick portion, are laminated so that the thin portions overlap and the thick portions do not overlap to form an unfired mother laminated body. This unfired mother laminated body is cut along predetermined cut lines that are vertical to each other to obtain a plurality of unfired ceramic element assemblies. By applying ceramic paste to cover exposed portions of inner electrode patterns exposed to lateral surfaces, side gap areas are formed between a first inner electrode pattern and first and second lateral surfaces of the unfired ceramic element assembly and between a second inner electrode pattern and the first and second lateral surfaces. |

Printed wiring board feed-through capacitor
A feed-through capacitor is constructed in a printed wiring board using alternating layers of metal capacitive layers and plastic dielectric layers of the printed wiring board. The large number of layers, the avoidance of ceramic layers and the flexible geometry of this device allow it to be used in many applications, particularly in those involving high power high current. Also, because it utilizes a printed wiring board, the capacitor can be made in numerous sizes and shapes. |
