Abstract: An approximation of a DCT and a quantization are to be applied subsequently to digital data for compression of this digital data. In order to improve the transform, a predetermined transform matrix is simplified to require less operations when applied to digital data. In addition, elements of the simplified transform matrix constituting irrational numbers are approximated by rational numbers. These measures are compensated by extending a predetermined quantization to include the operations which were removed in the simplification of the predetermined transform matrix. The included operations are further adjusted to compensate for the approximation of elements of the simplified transform matrix by rational numbers. If the simplified transform matrix and the extended quantization are used as basis for implementation, a fast transform with a good resulting quality can be achieved. An approximation of an IDCT employed in decompression of compressed digital data can be simplified correspondingly.

Abstract: A method and device for changing input states of an electronic device, the device comprising an input portion and being capable of carrying out user operations, the input states comprising a locked state, where the use of the input portion is significantly restricted, and an unlocked state, where the use of the input portion is not restricted, the locked and unlocked states being respectively enterable by a locking and unlocking input. A further input state is an intermediate unlocked state in which a limited operational use of the input portion is possible; which method comprises entering the intermediate unlocked state from the locked state, based on user input; detecting termination of a user operation in the intermediate unlocked state, and entering the locked state, in response thereto. There is also provided an input controller, a keypad and a mobile electronic device implementing these features.

Abstract: The present invention relates to a method, device and computer program product for exchanging and processing image data within the context of playing a wireless network based game. A first object is a reference object which is provided by a first party. At least one second object is a comparison object which is provided by at least one second party and the first party and the at least one second party are involved in a comparison procedure over a communication network. Information is established which is indicative of the first object and a task is generated which relates to the first object which is available to the at least one second party. The first party receives the at least one second object from the second party. The second object is compared to the first object, with a value generated based upon the comparison.

Abstract: A method for synchronizing an event in a first datastore and a second datastore. The method comprises the steps of selecting a first datastore comprising a plurality of events, selecting a second datastore, and providing a synchronization setting for an event in the plurality of events so as to indicate how synchronization between the first datastore and the second datastore is to be performed with respect to the event. The synchronization setting may indicate that a corresponding event in the second datastore is to be synchronized with the event in the first datastore, or that the event in the first datastore is to be synchronized with the corresponding event in the second datastore, or the synchronization setting may indicate that the first datastore obtains from the second datastore an update to the information of the event, adds the update to the event, and synchronizes the event based on the updated event.

Abstract: In one aspect thereof this invention provides a system and a method to operate a network node to facilitate conveying rights to digital content. The method includes forming a record in a collection of records of an occurrence of an acquisition of rights to a certain digital content by a first party and, in response to a receipt of a request through the network from a second party to obtain rights to the certain digital content, to examine the records and, if the record is found, to contact the first party through the network to solicit the first party to relinquish at least some remaining rights to the digital content, if any, held by the first party.

Abstract: The present invention relates to a method for activating actions. The method comprises the steps of defining an action, a portable device (9) related to it and, as a condition for activating the action, at least one item of position data, and determining the position of the portable device (9). When the position of the portable device (9) corresponds to the position data defined in an action, said action is activated. In the method, the information about actions is processed in a server (2), from which a data transmission connection can be set up to the device, in which the action data is transmitted from the server (2), to be activated.

Abstract: This invention describes a method for packaging and delivering secure internet-mail (I-mail) content reliably within a communication system (e.g., a mobile communication system) using a business model. The invention enables a business model of courier services like DHL or UPS for e-mail applications. The basic idea of the invention is to provide a packaging application at the user's terminal, but after the content has been packaged, to leave the delivery of the package to an operator-assisted system. For example, the transfer of the package from the terminal to the network, address resolution, making sure the receiver is able to read the content, security and charging are taken care by the system operators.

Abstract: One or more personalized models of one or more of a user's organs, systems, and/or the like may, for example, be run, and/or biological measurement data may, for instance, be obtained for the user. Comparison and/or the like of model output and obtained biological data may, for instance, be performed. A condition of the user may, for example, be deduced.
