Abstract: An optoelectronic device includes a substrate with a light emitter and a photodetector supported by the substrate. The light emitter and photodetector are stacked one on top of the other. At least one of the light emitter and photodetector is formed by a stack including the following order of layers: a first electrode layer, a hole transport layer, a quantum nano-structure layer (for example, a semiconductor nanoparticle layer, a quantum dot layer, a quantum rod layer or quantum well layer), an electron transport layer and a second electrode layer. An insulating layer is positioned between the light emitter and photodetector in the stack.

Abstract: In an embodiment a method for measuring ambient light includes successively synchronizing optical signal acquisition phases with extinction phases of a disruptive light source, wherein the disruptive light source periodically provides illumination phases and the extinction phases, accumulating, in each acquisition phase, photo-generated charges by at least one photosensitive pixel comprising a pinned photodiode, wherein an area of the pinned photodiode is less than or equal to 1/10 of an area of the at least one photosensitive pixel, transferring, for each pixel, the accumulated photo-generated charges to a sensing node, converting, for each pixel, the transferred charges to a voltage at a voltage node and converting, for each pixel, the transferred charges to a digital number

Abstract: A device includes a printed circuit board substrate, an antenna connected to the printed circuit board substrate, an amplifier connected to the printed circuit board substrate, and a matching track having a first end electrically connected to an input of the amplifier and a second end electrically connected to an output of the antenna. The matching track has an outgrowth that is symmetrical along a median axis of the outgrowth. The matching track is rectilinear and has a constant width over an initial part extending between the widening area and the first end. A median axis of the initial part and the median axis of the outgrowth form an angle comprised between 60 and 120°.

Abstract: A register bank of a channel of a direct memory access circuit is initialized. Transfer cycles are executed as configured by the register bank, and updates are made to the registers from a memory. At each transfer cycle, an operation is performed in accordance with a first field of the register bank to either: carry on the execution or generate a first signal and suspend the execution. In response to each reception of the first signal by a central processing unit, an operation is performed to either: generate a second signal or modify the content of the register band and/or record into the memory a first item representative of a next update of the register bank. A second signal is then generated.

Abstract: The system comprising a slave module and a master module. The master module comprises a master control module (CONTRM). The slave module comprises a determination module (DETER). The determination module (DETER) is configured to determine a value of a physical quantity of the slave module. The determination module (DETER) is configured to receive, from the master control module (CONTRM), a command to start counting and a command to end counting. The determination module (DETER) is configured to determine a number of oscillations, between reception of the command to start counting and reception of the command to end counting, of an oscillating signal of which a frequency depends on the value of the physical quantity.
