    Abstract: For the transmission of an MBMS content to a plurality of user equipment units, the use of a p2m channel may only be beneficial if the number of joined user equipment units exceeds a threshold. However, counting is made difficult due to the fact that idle mode UE, also a non joined UE, may reply to the notification, and hence pretend a higher number of UEs which are ready and able to receive the MBMS content. According to the present invention, when joining the MBMS service, a number which is only known to the user equipment unit, as well as to those RNCs which will deliver the MBMS service for which the UE has joined, is provided to the UE. Whenever the UE replies to a service notification, it uses this number. The RNC determines a corresponding number and in case the number received from the UE matches the number determined by the RNC, the UE is counted. Advantageously, an integrity protection may be provided for the notification reply for joined UEs which are still in the idle mode.

    Abstract: An electroluminescent light source includes a substrate and a layer structure applied to the substrate for emitting light at least on the side facing away from the substrate. The layer structure includes an electroluminescent layer between two electrodes. A partially transparent encapsulation device forms a closed volume around the layer structure, and is filled with a dielectric fluid which is substantially chemically inert with respect to the layer structure. The fluid contains particles for absorbing parts of the light emitted by the layer structure and for re-emitting light of a different wavelength. The density of the particles is selected such that the particles in the dielectric fluid are in the suspended state in the operational state of the light source.

    Abstract: Conventional transformers with fractional turns have pre-manufactured cores usually with a complicated structure. According to the present invention, a method is provided of manufacturing a planar transformer where a ferrite polymer compound is laminated to a PCB for forming the core of the transformer. Advantageously, this may allow for the provision of a cheap and robust transformer.
