Abstract: A measurement of the rotation speed of an object is made using a time-of-flight sensor configured to detect a passing of one or more of elements of the object through a given position. The time-of-flight sensor is further mounted on a one-person vehicle configured to protect the one-person vehicle against collisions through the making a time-of-flight measurement of a relative speed between the one-person vehicle and an obstacle.

Abstract: A voltage source device includes a voltage converter configured to generate a supply voltage at an output node of the voltage converter. A current source is configured to apply a current to a first output terminal of the voltage source device in order to detect a cable voltage drop. A compensation circuit is configured to generate a feedback signal based on a voltage at the first output terminal. The supply voltage is generated based on the feedback signal.

Abstract: A device for assembling at least two shots of a scene acquired by at least one sensor includes a memory and processing circuitry. The processing circuitry is configured to save, in the memory, a first data set contained in a first signal generated by each pixel of the sensor and indicative of a first shot of the scene, and a second data set contained in a second signal generated by each pixel of the sensor and indicative of a second shot of the scene. The processing circuitry is further configured to assemble the first and second shots on the basis of the content of the first and second data sets of a plurality of pixels in order to form a resulting scene.

Abstract: A charge pump generates an output voltage. A first circuit generates a pulse width-modulated signal as a function of a deviation between the output voltage and a setpoint voltage. A second circuit receives a periodic signal and conditions the supply of the periodic signal to a control input of the charge pump as a function of the state of the pulse width-modulated signal.

Abstract: An electronic device includes a carrier substrate having a front face and an electronic chip mounted on the front face. An encapsulation cover is mounted above the front face and bounds a chamber in which the chip is situated. A front opening is provided in front of an optical component of the chip. An optical element, designed to allow light to pass, is mounted on the cover in a position which covers the front opening of the cover. The optical element includes a central region designed to deviate light and a positioning pattern that is visible through the front opening. An additional mask is mounted on the encapsulation cover in a position which extends in front of the optical element. A local opening of the additional mask is situated in front of the optical component.

Abstract: A microcontroller includes distinct electronic functions and an interconnection circuit capable of transmitting in wireless fashion data between the functions. The microcontroller can be operated by writing configuration characteristics into a memory of the interconnection circuit for electronic functional circuits that do not have configuration characteristics contained in the memory and erasing configuration characteristics from the memory for electronic functional circuits that have configuration characteristics contained in the memory but are determined to not be able to wirelessly communicate with the interconnection circuit. Data can be wirelessly transmitted between the interconnection circuit and electronic functional circuits having configuration characteristics contained in the memory.

Abstract: A support substrate has first electric contacts in a front face. An electronic component is located above the front face of the support substrate and has second electric contacts facing the first electric contacts of the support substrate. An electric connection structure is interposed between corresponding first and second electric contacts of the support substrate and the electronic component, respectively. Each electric connection structure is formed by: a shim that is made of a first electrically conducting material, and a coating that is made of a second electrically conducting material (different from the first electrically conducting material). The coating surrounds the shim and is in contact with the corresponding first and second electric contacts of the support substrate and the electronic component.
