Abstract: An embodiment of a device for generating a note signal upon a manual input includes an operator to enable a user of the same as an input to define one or several points as an input signal, and a controller which is implemented to receive the input signal and to generate a note signal based on the input signal and an allocation function. The allocation function allocates one single or no tone to each point of a two-dimensional definition amount with a tone quality axis and a frequency axis. The definition amount has a plurality of base points. Here, exactly one tone is allocated to each of the base points.

Abstract: The invention relates to a waveguide system for distributing high-bandwidth signals in a multilayer circuit carrier. The waveguide system comprises at least one coplanar waveguide (2) and one or more ground wires (3, 4). The coplanar waveguide (2) is disposed with the ground wires (3, 4) associated therewith between at least two insulating layers (5, 6) of the circuit carrier. The surface of the two insulating layers oriented away from the plane of the waveguide (2) has electrically conductive layers (7, 8). Electrically conductive plated through-holes (9, 10) extend along the waveguide (2) substantially perpendicular to the plane of the waveguide. The ground wires (3, 4), the electrically conductive layers (7, 8), and the plated through-holes (9, 10) are electrically connected to ground potential. The waveguide system serves particularly for the three-dimensional distribution of high-bandwidth signals.

Abstract: This invention comprises a method of little complexity for selection of an optimized number of subscribers for transmission in wire-free message transmission systems having a plurality of antennas at the base station and having one or more antennas at the receivers, as well as space-division multiple access (SDMA) in conjunction with multiple access in the time domain or frequency domain. Subscribers with channels with little spatial correlation art selected for operation in the same time slot or frequency slot. In order to increase the throughput of the SDMA transmission method, with the relationship between the group size and the mean transmission power being taken into account. The invention interacts both with SDMA methods which do not allow any interference (Zero Forcing) and with methods with residual interference.

Abstract: The invention relates to a device and a method for the micromechanical positioning and handling of an object. The aim of the invention is to provide a device and an associated method for the micromechanical positioning and handling of objects by means of which the scanning speed can be increased and the positional accuracy be improved so that real time images or video rate images (ca. 25 images per second) having a lateral and vertical resolution in the nanometer range can be achieved. According to the invention, a monolithic component, preferably made of silicon, comprises a support element, an object carrier, a plurality of guide elements and elements for transmitting the movement, the preferably piezoresistive drive elements and the preferably piezoresistive position detectors being integrated into said monolithic component; Said micromechanical positioning device can be used, for example, in scanning probe microscopy and in nanopositioning and nanomanipulation technology.
