Abstract: Ejection device for fluid, comprising a solid body including: first semiconductor body including a chamber for containing the fluid, an ejection nozzle in fluid connection with the chamber, and an actuator operatively connected to the chamber to generate, in use, one or more pressure waves in the fluid such as to cause ejection of the fluid from the ejection nozzle; and a second semiconductor body including a channel for feeding the fluid to the chamber, coupled to the first semiconductor body, in such a way that the channel is in fluid connection with the chamber. The second semiconductor body integrates a damping cavity over which extends a damping membrane, the damping cavity and the damping membrane extending laterally to the channel for feeding the fluid.

Abstract: A method for real-time calibration of a gyroscope, configured for supplying a value of angular velocity that is function of a first angle of rotation about a first angular-sensing axis that includes defining a time interval, acquiring from an accelerometer an equivalent value of angular velocity that can be associated to the first angle of rotation; calculating a deviation between the value of angular velocity and the equivalent value of angular velocity; iteratively repeating the previous steps through the time interval, incrementing or decrementing an offset variable by a first predefined value on the basis of the values assumed by the deviations during the iterations, and updating the value of angular velocity as a function of the offset variable.

Abstract: A demodulator for demodulating the in-phase component of an input signal which is in-phase and quadrature modulated. The demodulator includes a register storing a phase calibration value and a temperature sensor that performs a plurality of temperature sensings. A compensating stage generates for each temperature sensed a corresponding first sample on the basis of the difference between the sensed temperature and a calibration temperature and a compensation function indicative of a relationship existing between the phase of the input signal and the temperature. A combination stage generates a plurality of second samples, each second sample being a function of the phase calibration value and a corresponding first sample. A generating stage generates a demodulating signal having a phase which depends on the second samples and a demodulating stage demodulates the input signal by means of the demodulating signal.

Abstract: A light-emitting device may include a semiconductor body having a first conductivity type, with a front side and a back side. The light-emitting device may also include a porous-silicon region which extends in the semiconductor body at the front side, and a cathode region in direct lateral contact with the porous-silicon region. The light-emitting device may further include a barrier region of electrically insulating material, which extends in direct contact with the cathode region at the bottom side of the cathode region so that, in use, an electric current flows in the semiconductor body through lateral portions of the cathode region.

Abstract: In an embodiment, a device may include a first sensor configured to generate first sensor data during a first time period and a second time period; a second sensor configured to be disabled during the first time period, the second sensor further being configured to generate second sensor data during the second time period; and a processor configured to determine a characteristic of the first sensor data during the first time period. The device may further include a classifying circuit configured to determine, during the first time period, whether the device has changed state based on the characteristic of the first sensor data, the classifying circuit further being configured to cause the second sensor to be enabled in response to a change in a state of the device.

Abstract: A driver circuit for driving, for example, ultrasonic transducers in medical equipment, such as ultrasound scanning equipment. The driver circuit includes first inputs receptive of a pulsed signal, second inputs receptive of an analog signal, an output for applying a pulsed drive signal or an analog drive signal to a load. A pair of output transistors of complementary polarities are positioned with their current paths in series between opposing supply lines with a connection point intermediate between the transistors of the pair of transistors. The connection point between output transistors is coupled to the output of the circuit. The control terminals of the output transistors, which are coupled together, may be coupled to the first inputs with the driver functioning as a pulser, or else coupled to the second inputs with the driver functioning as a linear driver.

Abstract: A laserbeam light source is controlled to avoid light sensitive regions around the laserbeam light source. One or more laserlight-sensitive regions are identified based on images of an area around the laserbeam light source, and indications of positions corresponding to the laserlight-sensitive regions are generated. The laserbeam light source is controlled based on the indications of the positions. The laserbeam light source may be controlled to deflect a laserlight beam away from laserlight-sensitive regions, to reduce an intensity of a laserlight beam directed towards a laserlight-sensitive region, etc. Motion estimation may be used to generate the indications of positions corresponding to the laserlight-sensitive regions.
