Abstract: A process for loading a secure memory image for a startup procedure of a microcontroller from an external non-volatile memory has the microcontroller configured to assume a locked state in which execution of any program is prevented pending a restart of the microcontroller when a data section of a secure memory image is faulty. The process includes the following steps: detection of the locked state of the microcontroller by a controller located outside of the microcontroller, institution of precautionary measures that lead to modified read data values of the memory image in a subsequent attempt by the microcontroller to read the memory image; and initiation of a restart of the microcontroller to cancel the locked state, and thus initiation of a renewed attempt to load the memory image. An assembly including a microcontroller, an external non-volatile memory and a controller implements such a process.

Abstract: A triggering device for a horn system of a motor vehicle is integrated in a steering wheel (2) of the motor vehicle. In order to prevent a relative movement of components associated with the steering wheel in relation to each other, but still enable a secure and reliable actuation of the triggering device of the horn system while at the same time allowing an optically compact and appealing design of the steering wheel (2), the invention proposes for the triggering device to comprise a first triggering unit (7), with which a parameter inherent in intended activation of the horn is detected. When such a parameter is detected, a first triggering signal can be emitted. The invention comprises a second triggering unit (11), with which a further parameter inherent in an intended activation of the horn is detected and a second triggering signal can be emitted.
