| 20120079895 | DEVICE AND METHOD FOR GENERATING AND/OR ARRANGING SEQUENCES OF ONE OR MORE FLUID SAMPLES IN A CARRIER FLUID - The invention relates to a device for generating and/or arranging sequences of a fluid sample in a carrier fluid. The invention comprises a microchannel having an inlet, an outlet and a nozzle opening therebetween leading into the microchannel. The invention further relates to a delivery unit, which pumps in the carrier fluid using a feed volume flow and suctions off the carrier fluid using a discharge volume flow. In a sample container, the nozzle opening is in contact with the fluid sample. By means of a control unit, the ratio between feed volume flow and discharge volume flow is varied. The cross-section of the nozzle opening is selected such that no carrier medium exits from the nozzle opening when the feed volume flow equals the discharge volume flow and that a fluid sample enters the nozzle opening when the discharge volume flow is greater than the feed volume flow. The invention further relates to a method for generating and/or arranging sequences of a fluid sample in a carrier fluid. | 04-05-2012 |

| 20110055985 | DEVICE AND METHOD FOR AN ATOMIC FORCE MICROSCOPE FOR THE STUDY AND MODIFICATION OF SURFACE PROPERTIES - The invention relates to a device for an atomic force microscope (AFM) for the study and/or modification of surface properties. The device comprises a cantilever (flexible bar) having an integrated, piezoresistive sensor, an integrated bimorphic actuator, and a measuring tip. The measuring tip carries at least two metal electrodes, which can be activated via electrical terminals. The measuring tip and/or the cantilever have at least one nanoscopic hole through which synchrotron radiation or laser light is directed onto the material surface to be studied. Furthermore, the invention relates to a method for the study and modification of surface properties and surface-proximal properties, which can be executed using such a device. To this end, atomic force microscopy (AFM), surface enhanced Raman scattering (SERS), photo emission spectroscopy (XPS, XAS), and material modification by local exposure are executed in sequence or simultaneously using the same device. | 03-03-2011 |

| 20100103690 | Headlight for a Motor Vehicle having a Masking Apparatus - The present invention relates to a headlight for a motor vehicle having a light source, which is arranged in a reflector, for emission of light beams in a light outlet direction, having a masking apparatus ( | 04-29-2010 |
| 20100054113 | Method for Selection of an Optimized Number of Subscribers in Mobile Radio Systems - 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. It is based on a novel interpretation of the ZF principle with the aid of orthogonal projection matrices, which allow the channel quality to be estimated with much less computation complexity, based on use or the transmission method. The possible subscriber combinations are sorted efficiently with the aid or a tree-like search algorithm. The method makes use of perfect channel knowledge or alternatively averaged channel statistics. Quality of service requirements for the subscriber as well as fairness criteria can be taken into account. | 03-04-2010 |
