Abstract: A method for evaluating a shallow water influence on a motor vessel driven by a drive output, including the continuous sequence of steps: determination of the water depth adjacent to the motor vessel and of a set-point speed in deep water that is expected from the predetermined drive output; calculation of the expected speed loss from the set-point speed as a function of the determined water depth; determination of the necessary output difference in the drive output that is needed in order to compensate for the expected speed loss; and display of the expected speed loss and the necessary output difference on a display unit.

Abstract: A method in which a user first receives from a Trust Center a generated, personalized, and certified key pair as well as components for producing encryption pairs. The user at any time himself produces an encryption key pair, marks the public part of this pair using the secret signature key relinquished to him, and transmits the result to the Trust Center, where the result is assigned to the user using the certified public part of the signature key pair.

Abstract: A rear mounting bracket or mount for center guide type drawer guides is universally adjustable relative to the cabinet in which it is mounted. A base attaches one side of the mounting bracket to a mounting surface. A drawer guide attaching member connects the other side of the mounting bracket to a furniture-type drawer guide. An adjusting structure forms the interface between the base and guide attaching member and allows positional adjustment of the drawer guide. The structure includes friction-creating ribs which resist movement between the base and the guide attaching member. The use of an external force is consequently required to move the guide attaching member relative to the base. Once the correct position of the guide attaching member has been established, the adjusting structure increases the resistance to adjustment of the rear end of the drawer guide.
