Abstract: The present invention relates to a method for operating a mobile navigation device, including the following process steps: a) approaching a parking space with a vehicle in which the mobile navigation device is disposed; b) identifying the current position of said vehicle as a parking space; c) automatically storing the arrival time at the parking space and/or a resulting arrival time derived from the arrival time at the parking space.

Abstract: A routing method for calculating a route between a first route endpoint (03), particularly a starting point, and a second route endpoint (04), particularly a destination, utilizes an electronically stored road map.

Abstract: A bearingless motor/generator comprises a rotatable part and a stationary part. The rotatable part is adapted to be rotated about an axis of rotation with respect to the stationary part. The stationary part has one or more windings for producing a drive field and a control field. The drive field is adapted to exert a torque on the rotatable part to transfer energy between the rotatable part and the stationary part. The control field is adapted to exert a force on the rotatable part to levitate the rotatable part. The force is adapted to be directed at an angle greater than 0° and less than 90° relative to the axis of rotation of the rotatable part.

Abstract: An electromagnetic suspension and rotary drive system comprises at least one conical bearingless motor/generator. Each conical bearingless motor/generator comprises a rotatable part and a stationary part. The rotatable part has an axis of rotation with respect to the stationary part. The stationary part has one or more windings for producing a drive field and a control field. The drive field is provided for exerting a torque on the rotatable part to transfer energy between the rotatable part and the stationary part. The control field is provided for exerting a force on the rotatable part to levitate the rotatable part. The force exerted by the conical bearingless motor/generator is adapted to be directed at an angle greater than 0° and less than 90° relative to the axis of rotation of the rotatable part.
