Abstract: A system for providing operating or charging current supply in different modes of operation includes an electric machine including a rotor and a stator having stator windings, at least one charge storage device, such as a battery, and an inverter disposed between the charge storage device terminals and the electric machine. A contact arrangement modifies electrical interconnections between phases of the inverter and the stator windings. In a supply mode, the electrical interconnections are controlled so that each inverter phase is electrically interconnected with a stator winding set having windings separated from each other by stator windings in other winding sets for driving the rotor of the electrical machine. In a charge mode, however, these interconnections are controlled so that each inverter phase is electrically interconnected with a stator winding set having windings directly adjacent to each other and are not separated from each other.

Abstract: The present invention relates to a device functioning as an electric motor or actuator (100, 100?) comprising: a housing (110) encapsulating a rotating member (120, 120?), one or several arrangements (130, 130?) for generating a magnetic field due to electrical current, a displaceable shaft (140, 140?) at least partly having exterior grooves (141, 141?), said rotating member having a portion (121, 121?) with inner grooves (122, 122?) corresponding to grooves on said shaft (140, 140?). The device comprises at least one magnetic element (150, 150?) arranged on an outer surface of said rotating member (120, 120?) substantially perpendicular to extension direction of said grooves (122, 122?) for interaction with said arrangement (130, 130?) and rotating said rotating member.

Abstract: In an object oriented computer system, a framework mechanism defines an infrastructure for allowing a user to flexibly define keys and their corresponding attributes. A special type of key called a specification key allows combinations of attributes to be specified, as well as set and range capabilities. An attribute retrieval policy is defined by a programmer to specify an algorithm or criteria that is used to calculating the desired attribute value. An attribute key controller contains key/value pairings for the attribute, contains the attribute retrieval policy, provides a maintenance interface for changing the attribute values; and provides a client interface for retrieving the attribute according to the attribute retrieval policy. The framework thus allows a user great flexibility in defining a suitable key/attribute retrieval mechanism by defining a suitable policy, defining one or more specification keys, and defining an associated controller.

Abstract: The transmittal of digital information from a customer to a client via the Internet is organized by employing a mediator and a handler. A customer requests the instantiation of a template from a mediator and the creation of necessary infrastructure for all subsequent media is done under the covers. After the instantiation of the template is requested, the mediator receives a message from the customer requesting the registration of digital information. The mediator then makes digital information available to said handler and receives a media key from the handler identifying the digital information. Finally, the mediator sends the media key to the customer. Thus, customers are enabled to use rich media services without the burden previously required by just contacting a media e-utility provider offering media services.
