Abstract
According to the invention, impact sensors are repeatedly interrogated during a polling mode and have to actively reply by emitting current pulses. If a sensor does not reply it is selectively addressed and can at that point signal a desired message. The master unit has full communications control over the bus so that data collisions can be avoided and very rapid transmission of the sensor signal is achieved. The master unit can change the communication priorities at any time.
