Abstract: A device for handling sensitive data comprises a first integrated circuitry forming a first trust zone and a second integrated circuitry forming a second trust zone. The first circuitry comprises a secure processing unit adapted for processing sensitive data, the second circuitry comprises a persistent memory area within its trust zone for storing sensitive data. The second integrated circuitry is separated from the first integrated circuitry, the processing unit of the first circuitry transfers sensitive data from the first trust zone to the second trust, the second circuitry transfers sensitive data stored in its persistent memory area to the processing unit of the first trust zone. The first and the second integrated circuitry comprise crypto means for securely transferring sensitive data based on a symmetrical crypto method using a secure key. The second integrated circuitry comprises means for initiating a new key generation to replace the active secure key.

Abstract: The present invention relates to a mixer truck with a water system and a water pump for generating the required water pressure in the water system and with further energy consumers, wherein the water pump and/or at least one further load is driven by an electric motor.

Abstract: The present disclosure relates to a belt conveyor for agitator vehicles consisting of a plurality of elements which are each connected to one another, pivotably to one another, by means of joints and which have driven transport belts for the transport of transport material such as concrete, sand, stone chippings or round gravel from the agitator vehicle to a pre-determined point, for example on a building site. In accordance with the present disclosure, the belt conveyor consists of four elements, of which the second and/or third element can be telescoped and the last element is not changeable in its length.
