摘要:
A wireless telecommunication system receives information from a wireless mobile unit and determines that the wireless mobile unit is within a designated region. Information specific to the designated region is received at a centrally located location-based message server. As the traveler enters the designated region, the wireless mobile unit then receives information specific to the designated region such as information relating to traffic problems or desired locations within the region. Alternatively, a problem is identified and designated as relating to a particular region, and wireless mobile units within the designated region are then identified so that information relating to the problem can be output thereto. As such, information specific to a region occupied to a traveler is received.
摘要:
A semiconductive conjugated copolymer comprises at least two chemically different monomer units which, when existing in their individual homopolymer forms, have different semiconductor bandgaps. The proportion of said at least two chemically different monomer units in the copolymer is selected to control the semiconductor bandgap of the copolymer so as to control the optical properties of the copolymer. The copolymer is formed in a manner enabling it to be laid down as a film without substantially affecting the luminescent characteristics of the copolymer and is stable at operational temperature.The semiconductor bandgap may be spatially modulated so as to increase the quantum efficiency of the copolymer when excited to luminesce, to select the wavelength of radiation omitted during luminescence or to select the refractive index of the copolymer.
摘要:
A method is provided for forming in a semiconductive conjugated polymer at least first and second regions having different optical properties. The method comprises: forming a layer of a precursor polymer and permitting the first region to come into contact with a reactant, such as an acid, and heat while permitting the second region to come into contact with a lower concentration of the reactant. The reactant affects the conversion conditions of the precursor polymer in such a way as to control the optical properties of at least the first region so that the optical properties of the first region are different from those of the second region.The precursor polymer may comprise a poly(arylene-1,2-ethanediyl) polymer, at least some of the ethane groups of which include a modifier group whose susceptibility to elimination is increased in the presence of the reactant.

摘要:
In a method for testing the thermally induced unbalance of a rotating machine part, in particular the rotor of a turbogenerator, the rotating machine part or the rotor balanced at normal temperature is brought in the demounted state first to nominal rotational speed and held at this, while its temperature is varied and, at the same time, the transient variations in oscillations of the rotating machine part or rotor which are caused are measured. During the test, the rotating machine part or the rotor is surrounded at least partially by a closed heating cell, a cooling medium flows around and/or flows through the rotating machine part or the rotor in the heating cell, and the heating of the rotating machine part or of the rotor takes place essentially due to the flow-dynamic losses arising from the interaction of the rotating machine part or of the rotor with the circulating cooling medium.
