Abstract: A method and apparatus for forming a thin solar cell having a substantially planar body comprising a first layer which includes at least one photoactive semiconductor layer. This first layer has a frontal light entrance face, a rear face, and side edge face. A second layer comprising an electrically conductive grid-shaped front contact and an anti-reflection layer is located on the frontal light entrance face. A third layer comprising a front cover glass is fastened substantially adjacent the anti-reflection layer and the front grid-shaped contact. A fourth layer, comprising an electrically conductive rear conductive contact, is located on the rear face of the first layer. Spaced apart from the first layer are two electrically interconnection pads. Each pad has a face suitable for an electrical interconnection.

Abstract: A method is disclosed for processing a signal having a monochromatic signal component with the aid of a digital filter. The method includes determining the real amplitude, phase and frequency of the monochromatic signal component of the signal. The signal is delayed for a time during which states of the digital filter are set to correspond to the determined real amplitude, the phase and the frequency of the monochromatic signal component. The signal is then applied to the input of the digital filter only after the states of the digital filter are set.

Abstract: The present invention relates to a signal processing method for a radar system. The transmitted signal here includes a polyphase code that is optimized to the desired range/Doppler range and that is repeated periodically over time.
