  • Patent number: 9286382
    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: A non-volatile memory of a complementary type includes sectors of memory cells, with each cell formed by a direct memory cell and a complementary memory cell. Each sector of the non-volatile memory is in a non-written condition when the corresponding memory cells are in equal states and is in a written condition wherein each location thereof stores a first logic value or a second logic value when the memory cells of the location are in a first combination of different states or in a second combination of different states, respectively. A sector is selected and a determination is made as to a number of memory cells in the programmed state and a number of memory cells in the erased state. From this information, the condition of the selected sector is identified from a comparison between the number of memory cells in the programmed state and the number of memory cells in the erased state.

  • Patent number: 9263942
    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.

  • Patent number: 9258139
    Abstract: Transmission of data frames over a channel in a communications network takes place on a slotted time base. A method comprises an evaluation, by at least one node of the network having a frame available for transmission, of whether the channel is available for transmission. If the channel is available for transmission, the available frame is transmitted over the channel in a subsequent slot of the slotted time base. If the channel is not available for transmission, owing to a frame (having a certain temporal length) being transmitted over the channel at a certain time, the slotted time base of the node is resynchronized as a function of the frame being transmitted. The resynchronization includes identifying, as a function of the certain temporal length, an interval of delay to evaluate again at a future time whether the channel is available for transmission.

  • Patent number: 9257996
    Abstract: An oscillator circuit may include a local oscillator to generate a carrier signal having a tunable frequency, a first modulator and a power amplifier coupled in cascade to the local oscillator to generate an output signal. The first modulator may be activated from a first modulating signal having a first frequency alternatively defining ON and OFF states of the first modulator. An estimator unit may receive the carrier signal during a time window and detect an estimated frequency variation of the carrier signal during the ON and OFF states. A compensation unit may include a second modulator to generate a compensation signal proportional to the estimated frequency variation and modulated with a second modulating frequency. The second modulating frequency may be substantially the same as the first modulating frequency, and the compensation signal may be added to a bias signal of the local oscillator to tune the tunable frequency.
