Abstract: An optical modulator includes an optical waveguide including at least a first PN junction phase shifter and a second PN junction phase shifter. A driver circuit drives operation of the first and second PN junction phase shifters in response to a pulse amplitude modulated (PAM) analog signal having 2n levels. The PAM analog signal is generated by a digital to analog converter that receives an n-bit input signal. In an implementation, the optical waveguide and PN junction phase shifters are formed on a first integrated circuit chip and the driver circuit is formed on a second integrated circuit chip that is stacked on and electrically connected to the first integrated circuit chip.

Abstract: A strained semiconductor layer is produced from a semiconductor layer extending on an insulating layer. A thermal oxidization is performed on the semiconductor layer across its entire thickness to form two bars extending in a direction of a transistor width. Insulating trenches are formed in a direction of a transistor length. A strain of the strained semiconductor layer is induced in one implementation before the thermal oxidation is performed. Alternatively, the strain is induced after the thermal oxidation is performed. The insulating trenches serve to release a component of the strain extending in the direction of transistor width. A component of the strain extending in the direction of transistor length is maintained. The bars and trenches delimit an active area of the transistor include source, drain and channel regions.

Abstract: Various embodiments provide an optimized image filter. The optimized image and video obtains an input image and selects a target pixel for modification. Difference values are then determined between the selected target pixel and each reference pixel of a search area. Subsequently, a weighting function is used to determine weight values for each of the reference pixels of the search area based on their respective difference value. The selected target pixel is then modified by the optimized image filter using the determined weight values. A new target pixel in an apply patch is then selected for modification. The new target pixel is modified using the previously determined weight values reassigned to a new set of reference pixels. The previously determined weight values are reassigned to the new set of reference pixels based on each of the new set of reference pixels' position relative to the new target pixel.

Abstract: A method determines a movement of an apparatus between capturing first and second images. The method includes testing model hypotheses of the movement by for example a RANSAC algorithm, operating on a set of first points in the first image and assumed corresponding second points in the second image to deliver the best model hypothesis. The testing includes, for each first point, calculating a corresponding estimated point using the tested model hypothesis, determining the back-projection error between the estimated point and the second point in the second image, and comparing each back projection error with a threshold. The testing comprises for each first point, determining a correction term based on an estimation of the depth of the first point in the first image and an estimation of the movement between the first and second images, and determining the threshold associated with the first point by using said correction term.

Abstract: A method estimates an ego-motion of an apparatus between a first image and a second image of a succession of images captured by the apparatus, in a SLAM type algorithm containing a localization part including the ego-motion estimating and a mapping part. The ego-motion comprises a 3D rotation of the apparatus and a position variation of the apparatus in the 3D space, and the ego-motion estimating comprises performing a first part and performing a second part after having performed the first part, the first part including estimating the 3D rotation of the apparatus and the second part including, the 3D rotation having been estimated, estimating the position variation of the apparatus in the 3D space.

Abstract: An integrated image sensor may include adjacent pixels, with each pixel including an active semiconductor region including a photodiode, an antireflection layer above the photodiode, a dielectric region above the antireflection layer and an optical filter to pass incident luminous radiation having a given wavelength. The antireflection layer may include an array of pads mutually separated by a dielectric material of the dielectric region. The array may be configured to allow simultaneous transmission of the incident luminous radiation and a diffraction of the incident luminous radiation producing diffracted radiations which have wavelengths below that of the incident radiation, and are attenuated with respect to the incident radiation.

Abstract: A method for securing a data processing system having a processing unit is disclosed. At least a group of N1 digital words of m1 bits is selected from among the set of M1 digital words. N1 is less than M1. These words are selected in such a way that each selected digital word differs from all the other selected digital words by a number of bits at least equal to an integer p which is at least equal to 2. The group of N1 digital words of m1 bits form at least one group of N1 executable digital instructions. The processing unit is configured to make it capable of executing each instruction of the at least one group of N1 executable digital instructions.
