  • Nano-reservoirs technology for use in bone and/or cartilage regeneration
    Patent number: 10034737
    Abstract: The present invention concerns a biomaterial comprising a nanofibrous scaffold made of polymers, such as poly(?-caprolactone) or collagen, coated with at least one layer pair consisting of a layer of polyanions and a layer of polycations, wherein said at least one layer pair incorporates a therapeutic molecule such as a growth factor. The biomaterial may optionally comprise living cells such as osteoblasts and/or chondrocytes.
    Type: Grant

  • Method and device for compressing digital data
    Patent number: 5768534
    Abstract: A data compression device having a decorrelation circuit (10), a circuit (12) for quantizing the decorrelated data and a control circuit (13) acting on the quantization step. The device includes is a circuit for calculating a histogram of the decorrelated data and for calculating the quantization step on the basis of this histogram (11) in order to force, in accordance with the coherence of the histogram, this quantization step. The latter is calculated on the basis of the distances between the local maximum values of the histogram.
