20110036974 | GUIDING SPRAY DROPLETS INTO AN INLET CAPILLARY OF A MASS SPECTROMETER - Charged droplets are guided along a defined path from a droplet source to a droplet sink. A focusing pseudopotential distribution generated by audio frequencies on electrodes of a guiding device guide the charged droplets from the droplet source to the droplet sink with low loss. The droplets can be driven along the droplet guide by a gas flow, an axial electric field or a combination of both. For example, charged droplets from a spray capillary of an electrospray ion source at atmospheric pressure may be introduced into the inlet capillary leading to the vacuum system of ion analyzers, a procedure similar to that used up to now in nanoelectrospraying, but with substantially higher flow rates. In the guiding device, the droplets can be manipulated in different ways, for example evaporated down to a desired size. The introduction of small droplets into gas-aspirating capillaries is of interest because it is possible to keep the droplets on axis by Bernoulli focusing and to guide them in large quantities and with low loss through the capillary. The ability to guide the droplets makes it also possible to install a segmented inlet capillary with intermediate pumping, which allows pumping capacity to be saved. Advantageously, the sensitivity of ion analyzers such as mass spectrometers or ion mobility spectrometers by at least one order of magnitude. | 02-17-2011 |
20120181423 | KINGDON ION TRAPS WITH HIGHER-ORDER CASSINI POTENTIALS - An electrostatic Kingdon ion trap in which ions can oscillate harmonically in the longitudinal direction, decoupled from their motions in the transverse direction is formed from at least three inner electrodes located inside a hollow outer housing electrode. The inner surface of the housing electrode and the outer surfaces of the inner electrodes are formed so that when a potential is applied between the housing and the inner electrodes, the potential distribution inside the housing contains not only a term for a harmonic potential well in the axial direction, but also a term for the potential distribution in the radial direction, that contains, independent of the axial coordinate, the equations for a family of Cassini curves of at least the third order. | 07-19-2012 |
20130037711 | INTRODUCTION OF IONS INTO ELECTROSTATIC ION TRAPS - Ions are introduced into a Kingdon ion trap in which the ions can oscillate harmonically in a potential well in the longitudinal direction, essentially decoupled from their transverse motion by a Kingdon ion guide, which can consist of a drill-hole through the wall of the ion trap housing electrodes and a central wire. An injection potential is first applied to the wire, but once the heaviest ions of interest have been injected into the trap, the potential of the wire is switched to the potential of the housing electrodes, to trap the ions in the trap. The ions introduced into the Kingdon ion trap may come from a small ion cloud, located in a Paul trap. | 02-14-2013 |

20110029574 | METHOD AND DEVICE FOR RECOGNIZING STRUCTURES IN METADATA FOR PARALLEL AUTOMATED EVALUATION OF PUBLICLY AVAILABLE DATA SETS AND REPORTING OF CONTROL INSTANCES - In a method for simultaneous observation and analysis of a plurality of data sets, in particular from webcams or sensors published over the Internet, atypical situations can be detected from a plurality of data sets of mostly low quality by producing metadata that are investigated for critical structures. Moreover, atypical situations can be recognized by comparing actual object mass properties of a data set with the target object mass properties of a data set.

20110191078 | Calibration of Stream Models and Stream Simulation Tools - Every year people die at mass events when the crowd gets out of control. Urbanization and the increasing popularity of mass events, from soccer games to religious celebrations, enforce this trend. Thus, there is a strong need to gain better control over crowd behavior. Simulation of pedestrian streams can help to achieve this goal. In order to be useful, crowd simulations must correctly reproduce real crowd behavior. This usually depends on the actual situation and a number of socio-cultural parameters. In other words, what ever model we come up with, it must be calibrated. Fundamental diagrams capture a large number of the socio-cultural characteristics in a very simple concept. Accordingly, a method to calibrate a pedestrian stream simulation tool is described to reproduce arbitrary fundamental diagrams (e.g. Waldmann diagram) with high accuracy. That is, it correctly reproduces a phenomenon (e.g. a given dependency of pedestrian speed on the crowd density). | 08-04-2011 |

Thus, conventional methods for simulation of object flows are improved. The method is suitable in particular for flows of persons. | 10-13-2011 |
