Abstract: The present invention relates to a method for the operation of an antenna group (1) having M?2 transmitters and N?2 receivers (3) for the digital beamforming. In the method, a coherent transmit signal is transmitted in a transmit-receive-cycle via each of the M transmitters (2) into an area to be monitored, and a coherent receive signal from the area is recorded by each of the N receivers (3) for each transmit signal so that M·N receive signals are obtained. To each receive signal, a combination of the respective transmitting transmitter (2) and the respective receiving receiver (3) is allocated. The M·N receive signals are processed by means of digital beamforming to obtain spatial information about objects in the area to be monitored.

Abstract: The invention relates to a method of determining material properties of a contact formed between a measurement tip of a microscopic probe and a sample surface of a sample material. According to the method, a distance modulation is applied for modulating a distance between a support of the microscopic probe end the sample surface in a direction essentially normal to the sample surface and wherein a normal force signal indicative of a normal force is measured and demodulated. In the method it is proposed that the material properties be determined using measurement data comprised in the demodulated normal force signal and related to a (concave) buckling deformation of the microscopic probe relative to and away from the sample surface.

Abstract: A gas phase process for the production of titanium dioxide powders having well-controlled crystalline and surface area characteristics is disclosed. In this process, which is preferably carried out in a laminar diffusion flame reactor, vapor phase TiCl.sub.4 and oxygen are mixed in a reaction area which is heated externally. The titanium dioxide powder formed is then collected. It is preferred that the heat source used be a hydrocarbon fueled (e.g., methane) flame. Optionally, a vapor phase dopant (such as SiCl.sub.4) may be added to the reaction mixture to desirably affect the physical properties of the titanium dioxide produced. In a particularly preferred embodiment, a corona electric field is positioned across the area where the combustion reaction takes place (i.e., the reaction area). High anatase, high surface area titanium dioxide powders made by this process are excellent photocatalysts. The products of this process and the use of those products as photocatalysts are also disclosed.

Abstract: An asymmetrical interferometer having two Josephson junctions with unequal contact areas. In accordance with the invention, the magnetic flux magnitudes of the control lines of the Josephson junctions are approximately equal in each Josephson junction. In a preferred embodiment, the length of the Josephson junctions along a direction parallel to the control line are equal to each other. Moreover, each Josephson junction is provided with a counterelectrode metalization, the counterelectrode metalizations having substantially equal widths measured in a direction orthogonal to the control line. The widths of the counterelectrode metalizations are larger than the width of an inductive connection between the Josephson junctions.

Abstract: A method for electroplating and mechanically honing surfaces of a light-ay workpiece is provided comprising placing the workpiece within a honing machine having honing stones and an electrolytic circuit including an electrolyte, applying to said workpiece a first coating by electrolytic deposition within said electrolyte with the honing stones disengaged from said surfaces, and effecting simultaneous honing and electrolytic deposition of a second coating by means of said electrolyte. In this manner the deposition of the necessary basic coating is combined with the procedural step of the simultaneous electroplating and mechanical honing in such a way that the basic coating is deposited in the hone-forming machine itself and with the same electrolytic fluid, so that there is no need for a preliminary plating in an additional unit that is separate from the hone-forming machine.
