    Abstract: A method for monitoring an activity of a connected object including a monitoring device, includes: performing, by a measurement stage of the monitoring device, a first periodic measurement of an internal signal representative of an activity of the connected object; performing, by a computation stage of the monitoring device, a first non-cryptographic computation of an activity parameter representative of the activity from the internal signal measured during the first periodic measurement; comparing, by a comparison stage of the monitoring device, between the activity parameter on completion of the first non-cryptographic computation and a range of settings of corresponding to the activity parameter; and triggering, by a control stage of the monitoring device, a safety action in response to a determination that the activity parameter is outside of the range of settings.

    Abstract: A method for transmitting power includes providing power using a contactless power transfer from a transmitter to a receiver that is mutually coupled with the transmitter. The method also includes managing and regulating the contactless power transfer being provided, where the managing and regulating are integrally and autonomously performed by the transmitter

    IPC: G06F13/42

    Abstract: Some embodiments include a method of communication between a master device and N slave devices on a synchronous data bus. The method includes selecting a slave device from among the N slave devices using a selection channel, where the master device and the N slave devices are coupled in series through the selection channel. The method also includes transmitting data between the master device and the selected slave device using a transmission channel, where the master device and the N slave devices are coupled in parallel through the transmission channel.

    Abstract: The receiver for a satellite positioning system includes at least one receive channel with an input stage configured to receive a satellite signals having different constellation frequencies belonging to one frequency band or to different frequency bands. The receive channel further includes a frequency transposition stage connected to the input stage (EE) and including a controllable local oscillator device configured to deliver different frequency transposition signals respectively adapted to the different constellation frequencies. A processing stage of the receive channel is connected to the frequency transposition stage and includes a control circuit configured to control the local oscillator device to sequentially and cyclically deliver the different frequency transposition signals.
