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: A method for reading or writing data at an address of a memory is disclosed. The data includes a number of consecutive words that each has a plurality of bits. The words are transferred to or from the memory in synchronization with a clock signal so that each word is transferred in one cycle of the clock signal. The bits are scrambled or unscrambled by applying a logic function to the bits of each word. The logic function is identical for the scrambling and the unscrambling and makes use of a bit-key that is dedicated to the word and is identical for the scrambling and the unscrambling. Each bit-key comes from a pseudo-random series generated based on the address.

Abstract: A stepper motor is driven according to step driving modes including a full-step driving mode, a half-step driving mode and micro-stepping modes. The stepper motor may also be driven in an acceleration phase. A method of controlling the stepper motor includes controlling the current step driving mode of the motor by a processing unit. During the acceleration phase of the stepper motor and the stepper motor being in driven in a current step driving mode other than the full-step driving mode, the processing unit tests, after each speed increase, if a remaining computing power of the processing unit is sufficient for control of the stepper motor to remain in the current step driving mode, and if not the processing unit, in presence of a first switching condition, switches control of the stepper motor to the driving mode having the closest coarser step.

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: The lighting of a person via incident light radiation is controlled to address dazzling. The light radiation originates from a source of light and passes through a medium of variable and controllable opacity. The position of the source of light relative to the person can vary. A zone of the eyes of the person and a position of the zone of the eyes relative to the medium is detected. A incidence of dazzling of the zone of the eyes is detected. In response to the detection, the direction of incidence of the light radiation is determined. From this determination, from the position of the zone of the eyes, a region of said medium is identified that has a projection on the face of the person which includes said zone of the eyes. The opacity of the region of the medium is then modified in a controlled manner to preclude dazzling.

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.

An adjustment of the control frequency is then made according to the received information. The modulation detection involves detecting variations in the control frequency.
