A cooling mechanism to dissipate thermal energy generated by the active electronic components of a graphics card assembly. The filter medium is supported at least on one side on a supporting tube. An adhesive structure adheres on outer sidewall of the microphone chip. Current pulses of a certain profile are used to enhance the rate, intensity andor power of inductive heating delivered by the heating element or coil andor to enhance the lifetime or reduce the cost of the inductive heating system. When and where to display private information using alternate frame sequencing can be determined using environmental sensors. It is also the aim of the invention to provide for a sufficient hardness of the areas of the bow which form the roller trolleys.
