Abstract: An autonomous spontaneous deployment deployable mast includes at least one elementary structural unit having a longitudinal deployment axis X and two platforms parallel to a plane YZ orthogonal to the axis X. The elementary structural unit includes N stages stacked above one another parallel to the longitudinal deployment axis X, where N is greater than 1. Each stage includes at least three longitudinal flexible tape-springs, the N stages being fixed to one another two by two by means of connecting platforms parallel to the plane YZ and two contiguous lower and upper stages being offset angularly relative to each other by rotation about the deployment axis X, the tape-springs of the lower stage being interleaved between the tape-springs of the upper stage.

Abstract: An image compression method comprises the following steps applied to at least one image: decorrelating the image by applying thereto a mathematical transform to obtain a set of coefficients, decomposing the image into blocks and, for each block of the image, quantizing the coefficients using a dead-zone uniform scalar quantizer having a semi-dead zone of size T and a quantization step size Δ, and coding the quantized coefficients, the size T of the semi-dead zone of the scalar quantizer being determined by minimizing the difference between an estimated quantization distortion D(T), dependent at least on size T, and a target quantization distortion Dc.

Abstract: A method for producing a mirror comprising a plurality of optical surfaces, the method comprises: a step of producing elements, step of assembling the elements with each other from the rear, a step of fixing the elements from the rear onto a supporting structure of the mirror, and a step of polishing subsequent to the step of fixing the elements in order to obtain the optical surfaces of the mirror and correct the residual positioning defects of the optical surfaces and polish them.
