Abstract: The method of determination of a depth map of a scene comprises generation of a distance map of the scene obtained by time of flight measurements, acquisition of two images of the scene from two different viewpoints, and stereoscopic processing of the two images taking into account the distance map. The generation of the distance map includes generation of distance histograms acquisition zone by acquisition zone of the scene, and the stereoscopic processing includes, for each region of the depth map corresponding to an acquisition zone, elementary processing taking into account the corresponding histogram.

Abstract: System, method, and circuitry for generating content for a programmable computing device based on user-selected configuration information. A settings registry is generated based on the user's selections. The settings registry and the user selected configuration information is utilized to generate the content, such as code, data, parameters, settings, etc. When the content is provided to the programmable computing device, the content initializes, configures, or controls one or more software and hardware aspects of the programmable computing device, such as boot sequence configurations, internal peripheral configurations, states of the programmable computing device, transitions between states of the programmable computing device, etc., and various combinations thereof.

Abstract: The present disclosure concerns an electronic device connected to an antenna. The electronic device delivers a first amplitude-modulated analog signal of a signal captured by the antenna, the capture signal associated with an electromagnetic field exhibiting intervals at a minimum level. The electronic device includes a first circuit, a second circuit, and a third circuit. The first circuit delivers a second analog signal by rectification and filters the first analog signal. The second circuit delivers a first binary signal based on the demodulation of the second analog signal. The third circuit couples the antenna to a resistor during each pause. The resistance value of the resistor depends on the maximum amplitude of the electromagnetic field before the pause.

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.
