摘要： Method to provide a TOF estimate by a TOF device. The method comprises: generating an electric echo signal indicative of an ultrasonic echo signal returned by a target body by the ultrasonic source signal; determining an envelope signal indicative of an envelope of the electric echo signal; generating a first TOF estimate by processing the electric echo signal; determining an envelope signal portion of the envelope signal based on a non-PSOA hyperparameter; and generating a second TOF estimate by processing the envelope signal portion through PSOA, the second TOF estimate having a measurement accuracy value greater than that of the first TOF estimate. PSOA is optimized based on a PSOA hyperparameter set. The non-PSOA hyperparameter and the PSOA hyperparameter set are selected among a plurality of choices based on the first TOF estimate, so as to obtain the second TOF estimate which has greater accuracy than the first TOF estimate.

摘要： A process for manufacturing a MEMS device includes forming a first structural layer of a first thickness on a substrate. First trenches are formed through the first structural layer, and masking regions separated by first openings are formed on the first structural layer. A second structural layer of a second thickness is formed on the first structural layer in direct contact with the first structural layer at the first openings and forms, together with the first structural layer, thick structural regions having a third thickness equal to the sum of the first and the second thicknesses. A plurality of second trenches are formed through the second structural layer, over the masking regions, and third trenches are formed through the first and the second structural layers by removing selective portions of the thick structural regions.

摘要： A DC-DC boost converter includes an inductor coupled between an input voltage and an input node, a diode coupled between the input node and an output node, and an output capacitor coupled between the output node and ground such that an output voltage is formed across the output capacitor. A switch selectively couples the input node to ground in response to a drive signal. Control loop circuitry includes an error amplifier to generate an analog error voltage based upon a comparison of a feedback voltage to a reference voltage, the feedback voltage being indicative of the output voltage, a quantizer to quantize the analog error voltage to produce a digital error signal, and a drive voltage generation circuit to generate the drive signal as having a duty cycle based upon the digital error signal.

摘要： In an embodiment, a method of processing an electrophysiological signal includes collecting the electrophysiological signal that is indicative of a level of attention of a human; filtering the electrophysiological signal via joint low-pass and high-pass filtering using a set of filtering parameters including low-pass filters parameters and high-pass filters parameters having a set of low-pass cut-off frequencies and a set of high-pass cut-off frequencies respectively. The method further includes applying artificial neural network processing to the filtered electrophysiological signal to extract therefrom a set of features of the electrophysiological signal. The method further includes applying classifier processing to the set of features extracted from the filtered electrophysiological signal and producing a classification signal indicative of the level of attention of the human. The method further includes generating a trigger signal to trigger a user circuit based on the classification signal.

摘要： A sensor device includes a passive infrared sensor, a control circuit, and a lens that directs infrared radiation onto the passive infrared sensor. The lens includes an obstruction that asymmetrically blocks transmission of infrared radiation through the lens. The control circuit is configured to determine the direction of crossing of individuals passing in front of the sensor device based on sensor signals from the passive infrared sensor.

摘要： A method forms an HEMT transistor of the normally off type, including: a semiconductor heterostructure, which comprises at least one first layer and one second layer, the second layer being set on top of the first layer; a trench, which extends through the second layer and a portion of the first layer; a gate region of conductive material, which extends in the trench; and a dielectric region, which extends in the trench, coats the gate region, and contacts the semiconductor heterostructure. A part of the trench is delimited laterally by a lateral structure that forms at least one first step. The semiconductor heterostructure forms a first edge and a second edge of the first step, the first edge being formed by the first layer.

摘要： A device includes a set of processing circuits arranged in subsets, a set of data memory banks coupled to a memory controller, a control unit, and an interconnect network. The processing circuits are configurable to read first input data from the data memory banks via the interconnect network and the memory controller, process the first input data to produce output data, and write the output data into the data memory banks via the interconnect network and the memory controller. The hardware accelerator device includes a set of configurable lock-step control units which interface the processing circuits to the interconnect network. Each configurable lock-step control unit is coupled to a subset of processing circuits and is selectively activatable to operate in a first operation mode, or in a second operation mode.

摘要： A light-emitter device comprising: a body of solid-state material; and a P-N junction in the body, including: a cathode region, having N-type conductivity; an anode region, having P-type conductivity, extending in direct contact with the cathode region and defining a light-emitting surface; and a depletion region around an interface between the anode and the cathode regions. The light-emitting surface has at least one indentation that extends towards the depletion region. The depletion region has a peak defectiveness area, housing irregularities in crystal lattice, in correspondence of said at least one indentation. The defectiveness area, which includes point defects, line defects, bulk defects, etc., is generated as a direct consequence of the formation of the indentation by an indenter or nanoindenter system. In the defectiveness area color centers are generated.
