  • Patent number: 11915529
    Abstract: A processing unit includes a first communication interface that is designed for communication with a server device and/or a mobile device. The processing unit also has a second communication interface, which is designed for communication with the mobile device. The processing unit further has an internal communication interface of the processing unit, which is designed for communication with a vehicle bus network of the vehicle. The processing unit is designed to receive vehicle access data, which is representative of an access authorization of a driver to the vehicle via the second communication interface. The processing unit is also designed to determine depending on the vehicle access data a release signal for enabling a use of the vehicle and to provide it to the internal communication interface. The processing unit is also designed to receive vehicle analysis data via the internal communication interface.

  • Patent number: 7862020
    Abstract: Signatures are successively conveyed one after another by a conveying system from a printing press to a stack-forming device, in which the signatures are separated into stacks by a separating device. A remaining number of non-stacked signatures of a current production is counted with a counting device. The separating device separates the remaining number of signatures of the current production into standard stacks of a varying length between a minimum length and a maximum length based on the number of the counted remaining signatures.

  • Patent number: 7168910
    Abstract: A device is used for transporting a horizontal stack from a stack support to an intermediate deposit, where the stack is formed in a gathering device with upright, lined-up signatures. The device is comprised of a horizontally and vertically displaceable clamp arranged above the stack support, wherein the clamp compresses the stack at the ends and transfers a strapped stack from the stack support to an adjacent intermediate deposit.

  • Patent number: 6568672
    Abstract: A device for forming a stack of successively arranged printed sheets has a stack support with support elements and a conveying device supplying printed sheets, arranged in an imbricated arrangement, in a vertical direction to the stack support. The printed sheets formed stacks on the stack support in a stack forming direction and the support elements define a leading end and a trailing end of the stacks. A controllable insertion device correlated with the stack support moves end plates into an intermediate position between the support elements and the leading and trailing ends of the stack, respectively. The insertion device has an insertion member arrangement with passages allowing the support elements to pass through and has a drive for moving the insertion member arrangement perpendicularly to the stack support for inserting the end plates. The insertion device has at least one interstice for receiving end plates.
