Abstract: An indirect time of flight sensor includes a matrix of pixels, wherein each pixel includes at least two controllable transfer devices. First conductive lines transmit first control signals to the transfer devices, these first signals being provided by a first circuit. A device is provided for illuminating a scene that is divided into at least two first areas. The device successively illuminates each first area. The matrix is similarly divided into at least two second areas. The matrix and illumination device are disposed such that each first area corresponds to one second area. The first circuit provides different first signals to the different second areas.

Abstract: Control over the operation of a dimmable light is supported by an interface circuit between the dimmable light and a near-field radio frequency communication controller. The interface circuit includes a first circuit that receives at least one control set point through a near-field radio frequency communication issued by the near-field radio frequency communication controller. A second circuit of the interface generates one or more electric signals in pulse width modulation based on the control set point.

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.
