Abstract: The present invention relates to accessing, distributing, and presenting hypermedia documents (5, 6). In particular the invention relates to a method for a hypermedia communication system comprising the steps of generating a hypermedia by presenting the hypermedia in a hypermedia description at a hypermedia server, requesting the hypermedia at a hypermedia client, deploying the hypermedia description from the server to said hypermedia client, presenting the hypermedia by translating the hypermedia description, where said hypermedia description comprising expression means for a reference (70) from an atemporal hypermedia object to a referred hypermedia object, where said method comprises the steps of generating, requesting, deploying, and presenting hypermedia, uniformly, using a hypermedia description comprising further expression means for a reference from a temporal hypermedia object (5) to a referred hypermedia object (5,6).

Abstract: The invention relates to the characterization of tunable lasers. One particular method of characterizing a semiconductor laser is useful for a laser having first and second tuning sections controlled by respective first and second tuning currents. The method includes measuring power output from the laser as a function of the first and second tuning currents, and creating an image of power as a function of the two tuning currents. The image is analyzed to determine different modes, each mode corresponding to limited ranges of the first and second tuning currents. A preferred combination of the first and second tuning currents is determined for each mode and an acceptable operating region is defined for each mode.

Abstract: The invention relates to an accounting advisor method for guiding a user of a mobile providing a service choice and invoking a selected service (P3), and account processing (P5, P6) at a subscriber's mobile telecommunication device that is enabled for processing multiple accounts and advising a user by further recording user behavior (P2), retrieving accounting information (P1), analyzing service and tariff constraints (P4, P5) based on recorded user behavior and retrieved accounting information, and deriving a recommended service and account selection (P7) based on said analyzing with respect to optimization criteria and optionally negotiating service and tariff characteristics (P6). The invention further relates to a mobile telecommunication device, a base station, and a computer software product.

Abstract: Gypsum-based composite boards or shaped bodies can be manufactured from a mixture comprising calcium sulfate dihydrate and water, and optionally reinforcement materials or fillers, and conventional additives, by shaping the mixture to a raw form and hardening the raw form with water at a pressure exceeding the saturation pressure of calcium sulfate dihydrate.
