Abstract: A multichannel sensor unit includes: a multichannel sensor detecting at least one physical variable and outputting sensor data representing the detected physical variable; a main memory storing the sensor data of at least two sensor channels; and at least one additional memory. Instantaneous sensor data are stored in response to a trigger signal in the main memory. The sensor unit outputs first sensor data of a first sensor channel, which are stored in the main memory, in response to a first read command, and stores the additional sensor data in the at least one additional memory in response to the first read command. The sensor unit outputs the sensor data stored in the at least one additional memory in response to a second read command, such that the sensor unit outputs the sensor data from the main memory and the additional memory asynchronously.

Abstract: A connecting element is proposed for weight measurement in a vehicle seat, which has connecting means and bus communications means. The connecting means make possible connecting to a single-wire bus. Furthermore, a method is proposed for making possible the bus communications between a control unit as master and at least one connecting element as slave. In this context, an address is assigned to the connecting element for the bus communications as a function of the serial number of the connecting element. Furthermore, a bus system is proposed having a control unit for activating personal protective means as a master, and at least two connecting elements which are configured for weight measurement in a vehicle seat. The bus system is developed as a single-wire bus.
