Abstract: A time series of face images of a human during a human activity are captured. A first artificial neural network (ANN) processing pipeline processes the captured time series of face images to provide a first attention level indicator signal. An electrophysiological signal indicative of the level of attention of the human during the activity is also captured. A second ANN processing pipeline processes the sensed electrophysiological signal to providing a second attention level indicator signal. A risk indicator signal is then generated based on at least one of the first attention level indicator and second attention level indicator. A user circuit is then triggered as a result of the risk indicator reaching or failing to reach at least one attention level threshold.

The actuation structure includes driving arms with piezoelectric material, elastically coupled to the tiltable structure by decoupling elastic elements that are stiff to out-of-plane movements but compliant to torsional movements. The tiltable structure is elastically coupled to the fixed structure at the first rotation axis using elastic suspension elements, while the fixed structure forms a frame surrounding the cavity with supporting elements. A lever mechanism is coupled between a supporting element and a driving arm.

Abstract: A system and method for determining handedness in a device. The system including a first electrode, a second electrode, a sensor, and a processing circuit coupled to each other. The first electrode is placed at a first location, and the second electrode is placed at a second location on the device—the first location is different from the second location. The electrodes are configured to sense a variation in an electrostatic field in response to a user interacting with the device. The sensor detects a differential potential between the first electrode and the second electrode, and the processing circuit determines whether the user is interacting with the device using a left hand or a right hand. The determining is based on data received from the sensor corresponding to the differential potential.

Abstract: An electronic device includes an integrated circuit (IC) with its second face bonded to a first surface of a first support. A conductive clip has a first portion that is elongate and extends across the IC, having its second surface bonded to a first face of the IC by a solder layer. A second portion of the clip extends from the first portion away from the IC toward a second support with the second surface bonded to a first surface of the second support. A first surface of the clip has a pattern formed therein including a depressed floor with fins extending upwardly therefrom. Through-holes extend through the depressed floor to the second surface of the clip. An encapsulating layer covers portions of the first and second supports, IC, and clip while leaving the first surface of the first portion exposed to permit heat to radiate away therefrom.

Abstract: A method for controlling a MOS transistor compares a first voltage between a drain and a source of the MOS transistor to a second controllable threshold voltage. When the first voltage is smaller than a third voltage, a fourth control voltage is applied to the MOS transistor that is greater than a fifth threshold voltage of the MOS transistor. When the first voltage is greater than the second voltage, the fourth control voltage applied to the MOS transistor is smaller than the fifth voltage. The second voltage is equal to a first constant value between a first time and a second time, and is equal to a second variable value between the second time and a third time. The second value is equal to a sum of the first voltage and a sixth positive voltage. The third time corresponds to a time when the first voltage inverts.

The resistance of the second resistor is adjusted by generating a second resistance trimming code based on the first resistance trimming code and writing the second resistance trimming code to a second register.

Abstract: A memory array includes sub-arrays with memory cells arranged in a row-column matrix where each row includes a word line and each sub-array column includes a local bit line. A control circuit supports a first operating mode where only one word line in the memory array is actuated during memory access and a second operating mode where one word line per sub-array is simultaneously actuated during an in-memory computation performed as a function of weight data stored in the memory and applied feature data. Computation circuitry coupling each memory cell to the local bit line for each column of the sub-array logically combines a bit of feature data for the in-memory computation with a bit of weight data to generate a logical output on the local bit line which is charge shared with the global bit line.

The PN junction is formed between a first region doped with the first type of dopant and a second region doped with a second type of dopant opposite to the first type of dopant. The first doped region is shaped so as to incorporate local variations in concentration of dopants that are configured, in response to a voltage between the second doped region and the semiconductor well that is greater than or equal to a level of a breakdown voltage of the PN junction, to generate a monotonic variation in the electrostatic potential between the first doped region and the semiconductor well.
