  • Patent number: 8847925
    Abstract: Arrangement (202) for a user input device, such as a touchscreen or a touchpad, comprising a substrate (206), such as an optically substantially transparent flex film or a multilayer film, said substrate comprising support electronics (212) for providing power, control and/or communications connection to further electronic components (210), a number of emitters and detectors (210) arranged to said substrate into contact with the support electronics, for emitting and detecting light, respectively, and a lightguide (208) provided, such as laminated, onto the substrate such that said emitters and detectors are optically coupled to the lightguide material, the properties of the lightguide including the refractive index of the lightguide material being selected and the emitters and detectors being configured so as to enable, when in use, total internal reflection (TIR) -type propagation of light within the lightguide between the emitters and detectors, and recognition of a touch on the basis of a drop in the TIR p

  • Patent number: 6985567
    Abstract: A communications network system and a corresponding method for starting an AoC service of a user are disclosed. The system comprises a control means for sending a protocol message comprising a MIME indication of an AoC application to a user equipment (UE). The user equipment receives the protocol message and activates the AoC application by using the MIME indication.
