Abstract: A cooling system comprises a heat sink that bears on an electronic component (120) on a printed circuit board, and a cooling channel for a coolant. The cooling channel has a cavity for the heat sink, and the heat sink is designed to be placed in the cavity based on a distance between the component and the printed circuit board such that the printed circuit board can be placed on the cooling channel at a predetermined spacing thereto, such that the component bears on the heat sink.

Abstract: A device and a method for frequency analysis. The frequency of an output signal is divided, and an auxiliary signal with a known frequency is subtracted from the low-frequency signal to define a low-frequency differential signal. The output frequency is determined on the basis of the frequency of the low-frequency differential signal.

Abstract: A method and a device are for converting a digital input signal to an analog output signal, for example in vehicle safety systems. In the method, a first and a second pulse-width modulated signal is used for generating a first and a second analog intermediate signal. The second intermediate signal is converted to a third intermediate signal, wherein this conversion is controlled by a third pulse-width modulated signal. A fourth analog intermediate signal is generated from the third intermediate signal. The analog output signal is then generated from the first intermediate signal and the fourth intermediate signal. The first, second and/or third pulse-width modulated signal is preferably but not necessarily derived from the same digital input signal.
