Abstract: A sensor of a reflected light signal for acquiring a depth map of the scene. Each depth pixel of the sensor includes at least one pair of photosites. Each pair of photosites incudes a first photosite of a first semiconductor substrate and a second photosite of a second substrate having the first substrate stacked thereon. Each pixel is configured to acquire, for each pair of photosites of the pixel, at least one sample of charges simultaneously photogenerated in photosensitive elements of the photosites of said pair.

Abstract: A device of acquisition of a depth image of a scene by detection of a reflected light signal. The device includes a stack of a first sensor and of a second sensor. The first sensor includes first depth photosites configured to acquire at least one first sample of charges photogenerated during first time periods. The second sensor includes second depth photosites arranged opposite the first photosites, the second photosites being configured to acquire at least one second sample of charges photogenerated during second time periods offset with respect to the first time periods by a first constant phase shift. The first sensor or the second sensor further includes third photosites configured to acquire at least one third sample during third time periods offset with respect to the first time periods by a second constant phase shift.

Abstract: This two-dimensional Fourier transform ultrasound imaging method includes by controlling transmitting and receiving transducers: obtaining M matrices MRm, 1≤m≤M, of sampled ultrasonic time signals; two-dimensional Fourier transforming each matrix MRm to obtain M spectral matrices FTMRm; converting each spectral matrix FTMRm to obtain M spectral images FTIm; combining the M spectral images FTIm and two-dimensional inverse Fourier transforming the resulting spectral image FTI to obtain an ultrasound image I. The conversion includes taking into account a change of propagation mode during a backscatter, by adding a parameter characterizing this change of mode in equations (SYS) of change of reference frame, and/or taking into account a reflection against a wall, by adding a phase shift term in a relation (REL) of matrix transformation.

Abstract: The present method of providing element a random for a cryptographic algorithm is implemented by an electronic calculator comprising a core and a set of memory/memories, the set of memory/memories including a reference memory having an intrinsic randomness in a predefined state of generating randoms.
The method comprises:
reading a reference message in a first memory zone, the first memory zone being included in the reference memory, the reading step being performed in the state of generating random elements of the reference memory;
writing the reference message in a second memory zone, distinct from the first memory zone, the second memory zone being included in the set of memory/memories;
subsequent reading of the reference message in the second memory zone, the reference message read in the second memory zone forming the random element for the cryptographic algorithm.-
