Abstract: A controller and a method for a hybrid drive, which includes an internal combustion engine and an electrical machine are provided. The internal combustion engine includes adjustment devices that deactivate the intake and exhaust valve opening actuation. The controller is designed in such a way that, in the case of at least one specified condition (such as regeneration during unfired overrun or in the case of electric travel, in particular in the case of operation with high activation frequency of the internal combustion engine, e.g., in charge sustaining or HEV operation), the intake and exhaust valves are kept at least approximately (preferably completely) closed at least approximately simultaneously while the internal combustion engine is unfired. The internal combustion engine must be connected to the electrical machine. If there is a disconnect clutch, the disconnect clutch is brought into the closed state or remains closed.

The compute scaling adjustment indicates an adjustment to a number of compute instances of the cloud computing system. The compute scaling application provides the compute scaling adjustment to the cloud computing system. The cloud computing system adjusts a number of allocated compute instances.

Abstract: An implantable electrode lead having proximal and distal ends, comprising an electrode lead body and a pulling element. The pulling element has first and second ends. At the first end, the pulling element is connected to the distal end of the electrode lead or in the vicinity of the electrode lead distal end; referred to as the distal region of the electrode lead. Proceeding from the joining site between the first end of the pulling element and the electrode lead, the pulling element extends from the first end thereof toward the second end thereof to the proximal end of the electrode lead. The pulling element, proceeding from the joining site, extends outside the electrode lead body. A tensile force exerted onto the second end of the pulling element exerts a bending moment onto the electrode lead distal region. This bending moment results in bending of the electrode lead distal region.

In a fourth step, the departure from the recuperation phase is completed.
