Abstract: The invention relates to a method for providing a terminal MS2 of a communications system with coded still image signals. In order to enable a further content adaptation for multimedia messages, it is proposed that the method comprises receiving coded video signals at a network element of said communications system, converting at least a part of said received coded video signals in said network element to coded still image signals, and delivering said coded still image signals to a terminal MS2 of said communication system. The computation required for said conversion can be minimized by exploiting the commonalities of video and still images compression methods that are based on the Discrete Cosine Transform scheme. Thus it is rendered possible to provide excerpts of transmitted video clips also to terminals not capable of handling at least this particular video clip. The invention equally relates to a corresponding communications system, network element and module for a network element.

Abstract: A method in reception of a multiplex signal, comprising one or more data units, and at least one framing data block in each multiplex signal. The method comprises: searching for said framing data block from a received multiplex signal; demultiplexing said one or more data units according to the information in said framing data block; generating one or more demultiplexed signals from said demultiplexed data units, and forwarding said demultiplexed signals for decoding (50). At multiplexing possible invalidity of demultiplexed video data units is detected (51), and as a response to a detected invalidity in a demultiplexed video data unit, an error indication to the demultiplexed video data signal is added (52).

Abstract: The invention relates to an electronic device having a housing, which has a housing wall with openings for control elements and/or display elements. An external wall element, which at least partially covers the housing wall, is detachably connected to the housing. The external wall element has openings which are aligned with the openings in the housing wall. As a result, by using different external wall elements the external appearance of the electronic device can be easily modified.

Abstract: A process of telecommunication between a plurality of subscriber stations in accomplished under control of a switching center which stores call numbers of the respective subscriber stations. Each of the subscriber stations requests registration with an additional subscriber identification at the switching center. The switching center assigns the additional subscriber identification to the respective call number. In addition, the switching center transfers to each of the subscriber stations at least the subscriber identifications of all of the other subscriber stations so that one of the stations can be selected.

Abstract: In accordance with the invention the channel equalization factors in a communication system can be calculated at a base station and transmitted to a mobile station in order to effect the equalization at reception. Alternatively, the channel equalization can be effected at the base station also in connection with the transmission to the mobile station, in addition to the normal equalization made at reception. The construction of the mobile station is simplified when the channel equalizer or the calculation of the equalization factors can be omitted.

Abstract: A satellite communication system has at least one satellite (1) with an antenna that generates a moving beam pattern on the surface of the earth. The beam pattern (3) is comprised of a plurality of sub-beams (4). A method of this invention determines an attitude correction signal for the satellite by the steps of: (a) providing at least one reference transmitter (10) at a known location on the surface of the earth; (b) transmitting at least one signal from the at least reference transmitter into at least one of the sub-beams; (c) receiving the at least one signal with the satellite antenna and transponding the received at least one signal to a ground station (8).

Abstract: A system uses a portable carrier for transporting multiple semiconductor wafers in a substantially particle free environment. A cassette freely received within the carrier for supporting the wafers in spaced generally stacked relationship is delivered to an environmentally clean load lock. A mini-environment defines an interior region adjacent the load lock for the engageable reception of the carrier and sealingly isolates the load lock chamber and the interior of the carrier from the surrounding atmosphere. Transfer mechanisms serve to retrieve the cassette from the carrier and move the carrier into the load lock chamber while maintaining it in a particle free environment. A first transport mechanism within the mini-environment retrieves the cassette from the carrier and moves it into its interior region and a second transport mechanism within the load lock retrieves the cassette from the interior region and moves it into the load lock chamber.

Abstract: Telephone numbers along with alphanumerical identifications representing them are stored in a memory of a mobile phone. The number is selected with quick dialing so that the user first scrolls the identification corresponding to the required number on the display (11), after which the call is initiated by pressing the activation key. In the method of this invention the display is a touch-sensitive display, and a field (24) representing an identification on the display is divided into two or more sections (25, 26, 27) each of which corresponds to a different telephone number, e.g. to work (21), home (22) or to mobile phone (23). The required number is selected by pressing the column corresponding to the required section.

Abstract: Method and apparatus for igniting an air/fuel spray (26) comprised of fuel droplets. The apparatus includes a coherent optical source (12) for introducing at least one pulse of coherent radiation into the air/fuel spray. The pulse generates free electrons and initiates a development of a plasma within the air/fuel spray. The coherent source maintains the pulse of coherent radiation and pumps the developing plasma to higher energies. The pulse is terminated at a time after the plasma has reached a predetermined energy and before ignition of the air/fuel spray. The non-linear ignition system of the invention employs a gas/vapor interface region at a fuel droplet surface and an electric field that extends from and exists outside of a fuel droplet. Free electrons are accelerated to higher energies by the electric field surrounding the fuel droplet. The accelerated electrons initiate a breakdown near adjacent fuel droplets and the liberation of further free electrons.

Abstract: Flexible translucent electroconductive plastic film electrodes are produced by perforating a normally nonconductive translucent plastic film, and then applying to both surfaces of the film thin layers of a conductive metal oxide such as indium-tin oxide. The conductive layers communicate through the perforations to form an electroconductive film electrode useful with an electroluminescent layer and a rear electrode to form lights, signs and similar electroluminescent laminates.
