    Abstract: The present invention relates to an internal heat exchanger of the coaxial tubular type for a motor vehicle air-conditioning circuit, comprising two, low-pressure and high-pressure, portions through which a coolant flows, and to a corresponding air-conditioning circuit incorporating same. This exchanger (E), of the coaxial tubular type, defines at least one radially internal passage (11), preferably for the low-pressure fluid inside an internal tube (10) and a radially external passage (21), preferably for the high-pressure fluid, formed between this internal tube and an external tube (20).

  • Patent number: 7944974
    Abstract: A method and apparatus for processing or compressing an n-dimensional digital signal by constructing a sparse representation which takes advantage of the signal geometrical regularity. The invention comprises a warped wavelet packet transform which performs a cascade of warped subband filtering along warping grids of sampling points adapted to the signal geometry. It also comprises a bandeletisation which decorrelates the warped wavelet packet coefficients to produce a sparse representation. An inverse warped wavelet packet transform and an inverse bandeletisation reconstruct a signal from its bandelet representation. The invention comprises a compression system which quantizes and codes the bandelet representation, a decompression system, a restoration system which enhances a signal by filtering its bandelet representation, and a feature vector extraction system for pattern recognition applications of a bandelet representation.

  • Publication number: 20100220783
    Abstract: For compressing a video signal, a local multiscale transform is applied to a frame of the video signal to obtain coefficient blocks. The coefficients of each block are distributed into a plurality of coefficient groups, and for at least one of the groups, a common exponent is determined for encoding the coefficients of the group, and respective mantissas are determined for quantizing the coefficients of the group in combination with the common exponent. Coding data including each exponent determined for a coefficient group and the mantissas quantizing the coefficients of the group in combination with this exponent are stored in an external frame buffer.

  • Patent number: 7327893
    Abstract: The invention concerns a method for compressing data, in particular images, by transform, in which method this data is projected onto a base of localized orthogonal or biorthogonal functions, such as wavelets. To quantize each of the localized functions with a quantization step that enables an overall set rate Rc to be satisfied, the method includes the following steps: a probability density model of coefficients in the form of a generalized Gaussian is associated with each subband, the parameters ? and ? of this density model are estimated, while minimizing the relative entropy, or Kullback-Leibler distance, between this model and the empirical distribution of coefficients of each subband, and from this model, for each subband, an optimum quantization step is determined such that the rate allocated is distributed in the various subbands and such that the total distortion is minimal.

  • Patent number: 7282803
    Abstract: An electronic circuit includes a substrate. A capacitor and at least one semiconductor component are supported by a surface of the substrate. A substantially planar screen, oriented parallel to the surface of the substrate and made of metallic material, is placed between the capacitor and the semiconductor component. Preferably, the semiconductor component is placed in proximity to the surface of the substrate and several superposed layers of insulating material cover the surface of the substrate and the semiconductor component. The capacitor is then placed within at least one layer of insulating material above the semiconductor component, and the screen is placed within an intermediate layer of insulating material between the layer incorporating the capacitor and the surface of the substrate.
