Abstract: A light regulation device includes at least one light sensor which provides at its output a real brightness value, at least one regulator to which a set brightness value can be supplied, besides the real value, and a number n of output connections, n being greater than or equal to two. Each output connection is coupled to the output of a regulator in order to modify the light flux which can be supplied to at least one of the lighting elements. The regulator is designed to determine a difference between set and real values, to verify whether this difference lies within or outside a predeterminable tolerance range, and, in the event that the difference lies outside the tolerance range, to modify accordingly the light flux from the lighting elements which can be connected to the n output connections. At least one limit of the tolerance range depends on the actual light flux value.

Abstract: The invention relates to a method for the sampling of biphase coded digital signals by reception means which have at least one signal input having switchable signal edge sensitivity or at least two signal inputs having different signal edge sensitivity for the reception of such signals. The signals to be received are sampled precisely once per data bit, namely during the transmission of the first half-bit. The signal edges (F1-F5) of each bit are utilized for synchronizing the signal input with the control signal and for detecting transmission errors. Each signal sampling (S1-S5) is followed by a time window (&Dgr;t) within which the reception of the signal edge of the present bit is expected and evaluated as permissible. The signal edge sensitivity of the at least one signal input is set as a function of the sampled logic level of the first half-bit of the respectively transmitted bit of the signal.
