An improved structure of a card reader is provided, which comprises of a sideway card ejection switch and a sliding housing. The method includes recording first measurement data relating to at least one measurement variable with the at least one measurement device with a first measurement data resolution within a first measurement cycle, transmitting the recorded first measurement data to the bus system at a first measurement frequency within the first measurement cycle. Each power regulator comprises a current supply module and voltage regulator module. The system includes a component for configuring at least a portion of the light path such that a subset of the plurality of potential target points are included in the light path. The conductive layer and the blocking insulating layer in the first and second peripheral regions are removed to expose at least a portion of the substrate in the first and second peripheral regions, while leaving the conductive layer and the blocking insulating layer in the cell region. The scaled motion search section includes a downscaling module that downscales the plurality of pictures to generate a plurality of downscaled pictures, wherein the downscaling module includes a horizontal downscaling filter and a vertical downscaling filter, and wherein the vertical downscaling filter generates downscaled pixels for a macroblock pair using only pixels from the macroblock pair.
