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: Disclosed herein is an optical module including a substrate, with an optical detector, laser emitter, and support structure being carried by the substrate. An optical layer includes a fixed portion carried by the support structure, a movable portion affixed between opposite sides of the fixed portion by a spring structure, and a lens system carried by the movable portion. The movable portion has at least one opening defined therein across which the lens system extends, with at least one supporting portion extending across the at least one opening to support the lens system. The optical layer further includes a MEMS actuator for in-plane movement of the movable portion with respect to the fixed portion.

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.

Abstract: A method for transmitting an IP data packet to an IP address associated with a host name is described. A first service message of a Short Message Service is transmitted to a Short Message Service gateway server. The first service message includes a host name resolution request for a host name. A second service message of the Short Message Service is received from the Short Message Service gateway server. The second service message includes an IP address associated with the host name. An IP data packet is transmitted to the IP address associated with the host name.

Abstract: A method for testing the hermetic seal of a packaged device, which includes: a package that delimits a device chamber; and a transducer device, which is arranged within the device chamber and generates an electrical signal indicating at least one physical quantity external to the package. The testing method includes the steps of: imposing a reference pressure in the device chamber; arranging the packaged device in a testing chamber in which a testing pressure is present, different from the reference pressure; and subsequently detecting possible pressure variations within the device chamber.

Abstract: In one example, a circuit includes a first node to receive an analog signal that is an amplitude modulated radio-frequency signal for a digital signal. An output node is configured to provide an output signal indicative of rising and falling edges of an envelope of the analog signal. The rising and falling edges are indicative of rising and falling edges of the digital signal. A first current path is disposed between a power supply node and the first node. The first current path includes a first transistor coupled between the first node and a first bias source. The first bias source is coupled between the first transistor and the power supply node. The output node is coupled to a first intermediate node in the first current path between the transistor and the first bias source. A control terminal of the first transistor is coupled to the output node via a feedback network.
