    • An adaptive receiver for base stations of CDMA mobile wireless systems corresponding to the IS-95 Standard. The receiver is designed as an incoherent rake receiver and includes an antenna array. The receiver is capable of analyzing a plurality of components of the same signal transmitted by a mobile station arriving at the antenna array via different propagation paths and from different directions with a time offset. To form virtual antenna directivity patterns for individual rake processing paths, which are adjusted to the directions of incidence of the signal paths to be analyzed, direction signature vectors are calculated and made available to the processing paths together with a signal propagation time that is required for synchronizing the signal components. The direction signature vectors are calculated iteratively from the antenna correlation matrices formed recursively for all possible signal delay times from pulse responses of the antenna arrays. The signal components associated with the processing paths are selected according to the average path powers determined for the individual signal delay times, and the path powers are also calculated from the antenna correlation matrices.

    • A ceramic consisting substantially of Al.sub.2 O.sub.3 as ceramic support, ceramic cover layer and/or ceramic supporting structure for heating conductors is described, which is electrochemically stable, which, in other words, does not decompose on application of a heating voltage, even in long-term operation at temperatures above 600.degree.. Such a ceramic exhibits a very small alkali metal content, of less than 0.2% by weight Na.sub.2 O and K.sub.2 O respectively. Particularly favorable processing, in particular pressing properties are exhibited by such a ceramic if it has 2.5 to 10% by weight of barium silicate or strontium silicate fluxes, the proportions of Na.sub.2 O, K.sub.2 O, CaO and MgO together make up less than 1% by weight, and the BaO or SrO:SiO.sub.2 molar ratio is between 2:1 and 1:12.5. Such a ceramic with a BaO:SiO.sub.2 ratio of 2.6:1 parts by weight is electrochemically stable up to approximately 1400.degree. C., and at 1300.degree. C. still exhibits a bending strength of approximately 300 N/mm.sup.2.

    • A device for controlling the exchange of energy between an electrical power network and a load includes a stationary charging station for establishing an energy connection between the electrical power network and a supply point. The charging station has an LS controller for sending and receiving control signals via a signal transmission path, and includes a SIM station installed on the load side having a SIM controller. The SIM controller sends a SIM identifier of the SIM station to the LS controller via a signal transmission path at time intervals, wherein the LS controller adds an amount of energy exchanged between the electrical power network and the load to an energy amount counter associated with the SIM identifier. The amount of energy exchanged between the electrical power network and the load via the energy connection in a time interval is below a specified measurement resolution of the energy amount counter.
