Un aparato electroestimulador de baja frecuencia para la prevención y curación de heridas crónicas que resultan de un padecimiento diabético u otra patología, por medio del cual se aplican estímulos eléctricos en forma de señal cuadrada bipolar y señal cuadrada bipolar pausada en al menos un canal de salida y a frecuencias y tiempos de terapia diferentes que dependerán de las necesidades específicas del paciente.

A method to determine real time image complexity in video streaming, IPTV and broadcast applications using a statistical model representing channel bandwidth variation and image complexity that considers scene content changes. Available channel bandwidth is distributed unevenly among multiple video streams in proportion to bandwidth variation and image complexity of the broadcast video stream. The distribution of available channel bandwidth is determined based upon an image complexity factor of each video stream as determined from probability matrices considering bandwidth variations and image complexity.

The invention relates to an oil well pipe for pipe expansion which is to be expanded in a well. The oil well pipe has both a chemical composition which contains by mass C: 0.05 to 0.08%, Si: 0.50% or below, Mn: 0.80 to 1.30%, P: 0.030% or below, S: 0.020% or below, Cr: 0.08 to 0.50%, N: 0.01% or below, Al: 0.005 to 0.06%, Ti: 0.05% or below, Cu: 0.50% or below, and Ni: 0.50% or below with the balance being Fe and impurities and a structure having a ferrite content of 80% or above. Further, the oil well pipe exhibits a yield strength of 276 to 379MPa and a uniform elongation of 16% or above, thus being excellent in pipe expandability.

The invention relates to a panel, particularly a floor panel (1, 2), comprising a core made of wood material or a wood material-plastic mixture (17), a top (18) and a bottom (19). On at least two opposing side edges (I, II), the panel has profiles that correspond to each other such that two identically configured panels (1, 2) can be connected to and interlocked with each other by a substantially vertical joining movement in the horizontal (H) and vertical (V) directions, wherein the interlocking in the vertical direction (V) can be brought about by at least one spring element (3) that can be moved in the horizontal direction (H), said element latching behind an interlocking edge (4) extending substantially in the horizontal direction (H) during the joining movement. The panel is characterized in that the spring element (3) is formed as one piece from the core (17).

An oil well pipe for expansion which is expanded in a well. The oil well pipe is made of a two-phase stainless steel which has a chemical composition containing, in terms of mass%, 0.005-0.03% carbon, 0.1-1.0% silicon, 0.2-2.0% manganese, up to 0.04% phosphorus, up to 0.015% sulfur, 18.0-27.0% chromium, 4.0-9.0% nickel, up to 0.040% aluminum, and 0.05-0.40% nitrogen, with the remainder being iron and impurities, and has a structure having an austenite content of 40-90%. The oil well pipe for expansion has a yield strength of 276-655 MPa and a uniform elongation more than 20%. The oil well pipe has excellent expansibility.

An audio decoding method and apparatus and an audio encoding method and apparatus which can efficiently process object-based audio signals are provided. The audio decoding method includes receiving a downmix signal and object-based side information, the downmix signal comprising at least two downmix channel signals; extracting gain information from the object- based side information and generating modification information for modifying the downmix channel signals on a channel-by-channel basis based on the gain information; and modifying the downmix channel signals by applying the modification information to the downmix channel signals.

An audio decoding method and apparatus and an audio encoding method and apparatus which can efficiently process object-based audio signals are provided. The audio decoding method includes receiving a downmix signal, which is obtained by downmixing a plurality of object signals, and object side information, extracting metadata from the object-side information and displaying an information regarding the object signals based on the metadata.

An audio decoding method and apparatus and an audio encoding method and apparatus which can efficiently process object-based audio signals are provided. The audio decoding method includes receiving first and second audio signals, which are object-encoded; generating third object energy information based on first object energy information included in the first audio signal and second object energy information included in the second audio signal; andgenerating a third audio signal by combining the first and second object signals and the third object energy information.

One or more devices on a network may be configured to provide firewall services for other devices on the network. Each of the firewall service suppliers may publish its capability with respect to firewall services and the service receivers may publish their requirements for firewall services. A manager function may broker the requests and offers to match services and requirements. A default firewall service may be provided to devices not publishing their requirements. Network topologies may be re-configured to first route traffic addressed to a device to its corresponding firewall service provider.
