Abstract: Noise in a communication channel is estimated by, in the absence of transmitted information packets, obtaining a plurality of sets of signal samples, and estimating noise power levels associated with the sets of signal samples and allotted to respective noise power classes. In the presence of at least one transmitted information packet, an information packet power level is estimated. A set of signal-to-noise ratios computed between the information packet power level and the noise power levels in the respective noise power classes are compared against a signal-to-noise threshold and partitioned into a first subset and a second subset of signal-to-noise ratios failing to exceed/exceeding, respectively, the threshold. One or more resulting impulsive noise parameters are computed as a function of impulsive noise parameters indicative of noise power levels in the signal-to-noise ratios in the first subset while disregarding impulsive noise parameters indicative of noise power levels in the second subset.

Abstract: A pulsed signal generator generates a pulsed signal having a pulse width intended to be equal to a given fraction of a pulse width of a reference clock. A reference current source outputs current having a reference magnitude, and a comparison current source outputs current having a magnitude that is a function of the reference magnitude and the given fraction. A comparison circuit compares a total current output by one of the reference current source and the comparison current source during pulses of the reference clock to a total current output by the other of the reference current source and the comparison current source during pulses of the pulsed signal equal in number to the pulses of the reference clock in order to determine whether the pulse width of the pulse signal is less than or equal to the given fraction of the pulse width of the reference clock.

Abstract: An HEMT includes: a heterostructure; a dielectric layer on the heterostructure; a gate electrode, which extends throughout the thickness of the dielectric layer; a source electrode; and a drain electrode. The dielectric layer extends between the gate electrode and the drain electrode and is absent between the gate electrode and the source electrode. In this way, the distance between the gate electrode and the source electrode can be designed in the absence of constraints due to a field plate that extends towards the source electrode.

Abstract: A MOSFET transistor device includes a functional layer of silicon carbide, having a first conductivity type. Gate structures are formed on a top surface of the functional layer and each includes a dielectric region and an electrode region. Body wells having a second conductivity type are formed within the functional layer, and the body wells are separated from one another by surface-separation regions. Source regions having the first conductivity type are formed within the body wells, laterally and partially underneath respective gate structures. Modified-doping regions are arranged in the surface-separation regions centrally thereto, underneath respective gate structures, in particular underneath the corresponding dielectric regions, and have a modified concentration of dopant as compared to the concentration of the functional layer.

Abstract: A multi-axis MEMS gyroscope includes a micromechanical detection structure having a substrate, a driving-mass arrangement, a driven-mass arrangement with a central window, and a sensing-mass arrangement which undergoes sensing movements in the presence of angular velocities about a first horizontal axis and a second horizontal axis. A sensing-electrode arrangement is fixed with respect to the substrate and is set underneath the sensing-mass arrangement. An anchorage assembly is set within the central window for constraining the driven-mass arrangement to the substrate at anchorage elements. The anchorage assembly includes a rigid structure suspended above the substrate that is elastically coupled to the driven mass by elastic connection elements at a central portion, and is coupled to the anchorage elements by elastic decoupling elements at end portions thereof.

Abstract: A leadframe includes a pattern of electrically-conductive formations with one or more sacrificial connection formations extending bridge-like between a pair of electrically-conductive formations. The sacrificial connection formation or formations are formed at one of the first surface and the second surface of the leadframe and have a thickness less than the leadframe thickness between the first surface and the second surface. A filling of electrically-insulating material is molded between the electrically-conductive formations of the leadframe, with electrically-insulating material molded between the connection formation(s) and the other surface of the leadframe. The sacrificial connection formation(s) counter deformation and displacement of parts during formation and pre-molding of the leadframe.

Abstract: A device has memory and processing circuitry coupled to the memory. The processing circuitry generates a resonant axis drive signal to drive a Micro Electro Mechanical System (MEMS) mirror system at a resonance frequency, and generates a linear axis drive signal to drive the MEMS mirror system at a linear frequency corresponding to a video frame rate. Generating the linear axis drive signal includes generating, using interpolation, a current set of shape values based on a stored set of shape values and an indication of the video frame rate. The linear axis drive signal is generated using the current set of shape values.

Abstract: An electronic device for detecting the presence of an occupant on board a vehicle includes an audio sensor to acquire sound-sensing signals on board the vehicle. A movement sensor acquires movement-sensing signals associated with movement of the vehicle and an environmental sensor acquires environmental-sensing signals on board the vehicle. A processing unit is coupled to the audio sensor, movement sensor, and environmental sensor processes the respective sound-sensing signals, movement-sensing signals, and environmental-sensing signals to monitor the presence on board the vehicle of the occupant and the absence of a responsible person to determine a situation of danger and to activate a corresponding alarm warning.

Abstract: 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.
