    摘要： Microswitch, comprising a base element (G) with a contact surface (KG) and an electrode (EG), and a switching element (S) with a contact surface (KS) and an electrode (ES) disposed opposite the electrode (EG) of the base element (G) at a distance (g). The switching element (S) is provided with a spring constant and is connected at least with a part of its edge portion with the base element (G) in a fixed manner. The contact surfaces (KG, KS) form a switching contact which is closable against a reaction force caused by the spring constant by means of a voltage applied to the electrodes (EG, ES). The base element (G) and the switching element (S) each comprise an auxiliary electrode (HG, HS) at a distance (a) from the electrode (EG, ES), to which a voltage can be applied. For opening the switching contact the electrodes (EG, ES) have a first voltage potential (U1) and the auxiliary electrodes have a second voltage potential (U2) of the voltage. The voltage potentials (U1, U2) effect an accumulation of positive and negative charge carriers on the surface portions of the electrodes (EG, ES) and the auxiliary electrodes (HG, HS) such that surface portions with positive and negative charge carriers are opposite each other in a lateral direction and surface portions with the same charge carriers are opposite each other in an orthogonal direction.

    摘要： A receiver and a method are applied in a wireless communication system for detecting interference with a coexisting radar system. A signal received from an antenna (100) is fed through an analog part (200) and a subsequent digital part (300) of said receiver. The receiver comprising an element (240, 260) with a-priori known attenuation values for a predefined set of frequencies, a first branch-off element (230, 252) for deriving a first detection signal (S10, S22) from the signal before said element (240, 260) and a second branch-off element (251, 270) for deriving a second detection signal (S21, S30, S20) from the signal after said element (240, 260). Further, the receiver comprising processing means (400) for processing the first (S10, S22) and the second (S21, S30, S20) detection signal such that a difference between the first (S10, S22) and second (S21, S30, S20) detection signal is comparable with a threshold value, wherein the threshold value depends on the a-priori known attenuation values of the element (240, 260). Depending on the comparison result, a frequency is identified as interfering or not a co-existing radar system.

    摘要： The application relates to a controllable filter (1) that is placed between an antenna on the one side and a receiver and transmitter on the other, where the receiver branch can be switched between two filter characteristics. In this way, a simple device for allowing simplex reception in the transmission band can be provided. This filter is preferably applied as a frontend filter (FP) in the fixed part of a cordless telephone system and/or in a mobile station to thereby provide said mobile station with walkie-talkie capabilities.
