Abstract: In an embodiment an apparatus includes a scanning photographic sensor configured to acquire an image, according to an integration time of the sensor, of a scene illuminated with periodically emitted light pulses by a source, so that the image has a regular succession of bands with different luminosities when the integration time of the sensor is different from a period of the light pulses, a processor configured to generate a signature vector representative of the regular succession of bands with different luminosities being present in the image acquired by the photographic sensor, wherein the signature vector is independent of a reflectance of an objects of the scene and of a level of light in the scene, determine a frequency of the bands in the image on basis of the generated signature vector and determine the period of the pulses of the source on basis of the determined frequency of the bands in the image, and a controller configured to adjust the integration time of the photographic sensor so that the integration time is a multiple of the determined period of the light pulses of the source.

Abstract: System, method, and circuitry for generating a linker model for use by a toolchain associated with a programmable computing device. One or more regions in the memory resources available to the programmable computing devices is defined for used by an application executing on the programmable computing device. One or more sections is defined for those regions for use by the application. Resource boundaries are generated for the application based on the defined regions and the defined sections. A user is enabled to modify the defined regions or the defined sections or the generated resource boundaries. A linker model is then generated based on the available memory resources, the defined regions, the defined sections, and the generated resource boundaries. This linker model is then utilized to generate a linker script for the programmable computing device based the linker syntax compatible with a toolchain linker for the programmable computing device.

Abstract: In one embodiment, an object can communicate contactlessly with a reader using active load modulation. The method includes detecting a sensing magnetic field emitted by the reader, initializing a phase-locked loop of the object, detecting a stopping of the sensing magnetic field emitted by the reader before initializing the phase-locked loop of the object is complete, calibrating an oscillator of the phase-locked loop on the basis of an internal clock of the object, detecting a new sensing magnetic field of the reader after calibrating the oscillator, and implementing the phase-locked loop to adjust the phase of the oscillator after detecting a new sensing magnetic field.

Abstract: The method for processing a matrix of pixels each containing an original red, green, blue, or infrared component, comprises at least one interpolation of an interpolated component different from the original component of a pixel of interest from the components of a group of pixels neighboring the pixel of interest. The interpolation comprises: a calculation of the sum of the components of reference pixels weighted by a respectively assigned weight, the reference pixels being pixels of the group having the same original component as the interpolated component, an evaluation of the spatial uniformity of an environment, within the group of each reference pixel, a calculation of the weights assigned to the reference pixels at values which are normalized and proportional to the respective spatial uniformity.

Abstract: An embodiment method for estimating a missing or incorrect value in a table of values generated by a photosite matrix comprises a definition of a zone of the table comprising the value to be estimated and other values, referred to as neighboring values, and an estimation of the value to be estimated based on the primary neighboring values and the weight associated with these primary neighboring values, wherein a weight of each neighboring value, referred to as primary neighboring value, of the same colorimetric component as that of the missing or incorrect value to be estimated, is determined according to differences between neighboring values disposed on an axis and neighboring values disposed parallel with this axis and positioned in relation to this axis on the same side as the primary neighboring value for which the weight is determined.

Abstract: An electronic device includes a near-field communication module and a powering circuit for delivering a power supply voltage to the near-field communication module. When the near-field communication module is in a low power mode, the powering circuit is configured for an operational mode where it is periodically started to provide the power supply voltage.
