Patent application numberDescriptionPublished
20110197678ACCELERATION SENSOR HAVING AN ELECTRODE BRIDGE - A capacitive micromechanical acceleration sensor has a substrate and a micromechanical functional layer situated above the substrate. A seismic mass, a suspension and fixed electrodes are situated in the micromechanical functional layer. The fixed electrodes are electrically connected to one another on a first and second side, respectively, of the suspension using buried conductor tracks. The fixed electrodes are connected to one another between the first and second side of the suspension using first and second conductors in the micromechanical functional layer.08-18-2011

20110068419MICROMECHANICAL SYSTEM - A micromechanical system includes a substrate, a first conductive layer situated above the substrate and a second conductive layer situated above the first conductive layer. The first conductive layer and the second conductive layer are conductively interconnected by a connecting element. The connecting element has a conductive edge surrounding a nonconductive region.03-24-2011
20110079863Micromechanical structure, method for manufacturing a micromechanical structure, and use of a micromechanical structure - A micromechanical structure which includes a substrate having a main plane of extension, and a seismic mass which is movable relative to the substrate. The micromechanical structure includes a fixed electrode which is connected to the substrate, and a counterelectrode which is connected to the seismic mass. The fixed electrode has a first fixed electrode region and a second fixed electrode region which is connected in an electrically conductive manner to the first fixed electrode region. The counterelectrode is partially situated between the first and the second fixed electrode region, perpendicular to the main plane of extension.04-07-2011
20110083506Micromechanical structure and method for manufacturing a micromechanical structure - A micromechanical structure includes: a substrate; a seismic mass movable relative to the substrate along a first direction parallel to a main plane of extension of the substrate; a first electrode structure is connected to the substrate; and a second electrode structure connected to the substrate. The seismic mass includes a counterelectrode structure having finger electrodes situated between first finger electrodes of the first electrode structure and second finger electrodes of the second electrode structure, along the first direction. The first electrode structure is fastened to the substrate by a first anchoring element in a central region of the micromechanical structure, and the second electrode structure is anchored to the substrate by a second anchoring element situated in the central region.04-14-2011

20080313613Method for statically checking an object-oriented computer program module - A method for statically checking an object-oriented computer program module includes the step of identifying objects within a computer program module, at least one of the objects having a plurality of references thereto, possibly from multiple clients. A discipline of permissions is imposed on the objects identified within the computer program module. The permissions enable tracking, from among a discrete set of changeable states, a subset of states each object might be in. A determination is made regarding whether the imposed permissions are violated by a potential reference to any of the identified objects. The results of the determination are output to a user.12-18-2008

20100171037COMPACT SCANNING ELECTRON MICROSCOPE - A compact electron microscope uses a removable sample holder having walls that form a part of the vacuum region in which the sample resides. By using the removable sample holder to contain the vacuum, the volume of air requiring evacuation before imaging is greatly reduced and the microscope can be evacuated rapidly. In a preferred embodiment, a sliding vacuum seal allows the sample holder to be positioned under the electron column, and the sample holder is first passed under a vacuum buffer to remove air in the sample holder.07-08-2010
20100194874User Interface for an Electron Microscope - A user interface for operation of a scanning electron microscope device that combines lower magnification reference images and higher magnification images on the same screen to make it easier for a user who is not used to the high magnification of electron microscopes to readily determine where on the sample an image is being obtained and to understand the relationship between that image and the rest of the sample. Additionally, other screens, such as, for example, an archive screen and a settings screen allow the user to compare saved images and adjust the settings of the system, respectively.08-05-2010
20100230590Compact Scanning Electron Microscope - A compact electron microscope is robust, simple to operate, and preferably requires no special utilities. Imaging can begin shortly after a sample is inserted. A preferred simplified design includes permanent magnets for focusing, lack a vacuum controller and vacuum gauge, and uses a backscattered electron detector and no secondary electron detector.09-16-2010

20100149522METHOD FOR SIMULATING THE TRANSMISSION CHARACTERISTICS OF OPTICAL MULTIMODE WAVEGUIDES - A method for determining optical characteristics of a channel waveguide by way of beam tracking by calculating a profile of sample beams using geometrical optics, in which first the profile is determined as a curve by projection into a two-dimensional area, then a three-dimensional area is determined by the curve, in which area the three-dimensional profile is determined as a substantially two-dimensional problem. A device or installation and a software product which use the method are also provided.06-17-2010
