Abstract: A display includes a display panel and a circuit. The circuit controls the display panel according to at least one control mode such as a pulse width modulation control mode. A method for determining a state of the display includes: acquiring samples from a channel of an ambient light sensor disposed below the display panel; supplying the samples to a processing circuit; detecting, by the processing circuit and based on said samples, whether the display panel is controlled in pulse width modulation; and following detecting the pulse width modulation control mode, calculating by the processing circuit a duty cycle from the samples.

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: An integrated circuit includes a computer unit configured to execute the neural network. Parameters of the neural network are stored in a first memory. Data supplied at the input of the neural network or generated by the neural network are stored in a second memory. A first barrel shifter circuit transmits data from the second memory to the computer unit. A second barrel shifter circuit delivers data generated during the execution of the neural network by the computer unit to the second memory. A control unit is configured to control the computer unit, the first and second barrel shifter circuits, and accesses to the first memory and to the second memory.

Abstract: A method is for detecting one or more objects in a detection zone using a time-of-flight sensor. The method includes emitting optical radiation via the emission circuitry of the sensor and subsequently capturing the reflected optical radiation using the reception circuitry. This captured radiation is quantified in terms of photons, and measurement circuitry determines both the amount of these photons and the distance from the sensor to the object(s). An analysis of the photon count, combined with the calculated distance, is used to determine the presence or absence of objects within the detection zone.

Abstract: An optoelectronic device includes an emitter of light rays and a receiver of light rays. The emitter is encapsulated in a transparent block. An opaque conductive layer is applied to a top surface and a side surface of the transparent block. The receiver is mounted to the opaque conductive layer at the top surface. An electrical connection is made between the receiver and the opaque conductive layer. A conductive strip is also mounted to the side surface of the transparent block and isolated from the opaque conductive layer. A further electrical connection is made between the receiver and the conductive strip.

Abstract: A method includes receiving a selection signal from a third-party device and a status signal from the third-party device. A data signal from the third-party device is latched when both the selection signal and the status signal are active. In addition, a second selection signal and a second status signal can be received from a second third-party device and a second data signal latched when both the second selection signal and the second status signal are active.
