Abstract: A memory stores a program to be executed by a microprocessor. The program includes a first program part and a second program part. An authenticator is configured to authenticate the program and includes a module that is external to the microprocessor and configured to authenticate said first program part when the microprocessor is inactive. The authenticator further activates the microprocessor to execute the first program part and authenticate said second program part using instructions of the first program part if the module has authenticated the first program part. The microprocessor then executes the second program part if the microprocessor has authenticated said second program part.

Abstract: An embodiment method executes instructions, each corresponding to switching a signal, a delay, and a condition selected among first, second, or third conditions. Each execution includes performing, after the delay, switching the signal if the condition is the first condition, if the condition is the second condition and a flag is in an active state, or if the condition is the third condition and the flag is in an inactive state, or not switching the signal if the condition is the second condition and the flag is in the inactive state, or if the condition is the third condition and the flag is in the active state. A first instruction represents a first switching of a first signal, a first delay, and the second condition, and is immediately followed by a second instruction representing the first switching of the first signal, a second delay, and the third condition.

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: A method for vehicle parking assistance during a parking maneuver of the vehicle includes detecting an obstacle in a detection space outside the vehicle. Successive measurements are taken of the distance or distances separating the vehicle and the obstacle and the position or positions of the obstacle relative to the vehicle. Depending on the results of the measurements, human speech voice messages are generated that provide parking assistance. The voice messages are broadcasted in the passenger compartment of the vehicle.

Abstract: Contactless power transfer from a transmitter to a receiver is managed. A magnetic field is generated by the transmitter from a command at a control frequency for a switching resonant circuit. The receiver communicates information to the transmitter through modulation of the magnetic field. The modulation is detected by the transmitter so as to extract the information. An adjustment of the control frequency is then made according to the received information. The modulation detection involves detecting variations in the control frequency.
