Abstract: An electrostatically actuated oscillating structure includes a first stator subregion, a second stator subregion, a first rotor subregion and a second rotor subregion. Torsional elastic elements mounted to the first and second rotor subregions define an axis of rotation. A mobile element is coupled to the torsional elastic elements. The stator subregions are electrostatically coupled to respective regions of actuation on the mobile element. The stator subregions exhibit an element of structural asymmetry such that the electrostatic coupling surface between the first stator subregion and the first actuation region differs from the electrostatic coupling surface between the second stator subregion and the second actuation region.

Abstract: A method of PWM regulating a motor through a half-bridge drive stage includes sampling the motor current to obtain sampled values during driving intervals or during current decay intervals, and comparing a last sampled value with a current threshold. The motor is coupled in a slow decay electrical path for the duration of a current decay interval if the last sampled value does not exceed the current threshold. Otherwise the motor is coupled in a fast decay electrical path for a portion of the duration of the current decay interval, and is coupled in the slow decay electrical path for a remaining part of the duration of the same current decay interval.

Abstract: A method for simultaneous playback of audio tracks from digital transceiver devices, which are adapted to define a communication network. The digital devices store audio tracks to be played. One of the digital devices is actuated as a Master device (M) and the remaining N digital devices as Slave devices. The master device generates a pilot signal by selecting a pilot audio track to be played from among stored audio tracks and by adding a synchronization frequency (fS) to the pilot audio track, having an assigned value that falls out of the sound wave frequency range. The Slave devices receive a pilot portion of the pilot signal and extract the synchronization frequency and the received part of the pilot audio track. The slave devices use the pilot to identify a stored track to be played using the synchronization frequency as a sampling frequency.

Abstract: An energy-scavenging interface receives an input signal from a transducer and supplies an output signal to a load. A switch is connected between the transducer and a reference node, and a diode is connected between the transducer and the load. A control circuit closes the switch for a time interval to permit energy storage in the transducer. A scale copy of a peak value of stored electric current is obtained. The switch is opened when the time interval elapses and the stored energy exceeds a threshold. The stored energy is then released to supply the load through the diode. The switch remains open as long as the value of current in the output signal exceeds the value of the scaled copy of the peak value.
