20090266316 | Rotary Piston Engine - The rotary reciprocating piston engine as a rotor rotatably journaled in a housing and a plurality of pistons movable in radial direction in the rotor between outer and inner dead points. Each piston has a piston rod mounted on a transverse shaft carrying at each end a sliding element which is displaceable in radial grooves formed in the rotor on both sides of the piston. The sliding elements are each provided on the outer side thereof facing away from the piston with a pin received in a housing-fixed star-shaped endless guide groove. The guide groove extends about the axis of rotation of the rotor and controls the movement of the pistons in radial direction between the inner and outer deadpoints. | 10-29-2009 |

20090179303 | Vertical Bipolar Transistor - A vertical heterobipolar transistor comprising a substrate of semiconductor material of a first conductivity type and an insulation region provided therein, a first semiconductor electrode arranged in an opening of the insulation region and comprising monocrystalline semiconductor material of a second conductivity type, which is either in the form of a collector or an emitter, and which has a first heightwise portion and an adjoining second heightwise portion which is further away from the substrate interior in a heightwise direction, wherein only the first heightwise portion is enclosed by the insulation region in lateral directions perpendicular to the heightwise direction, a second semiconductor electrode of semiconductor material of the second conductivity type, which is in the form of the other type of semiconductor electrode, a base of monocrystalline semiconductor material of the first conductivity type, and a base connection region having a monocrystalline portion which in a lateral direction laterally surrounds the second heightwise portion, which is further towards the substrate interior as viewed from the base, of the first semiconductor electrode, and which rests with its underside directly on the insulation region. | 07-16-2009 |
20090206335 | Bipolar complementary semiconductor device - The invention relates to a BiCMOS device comprising a substrate having a first type of conductivity and a number of active regions that are provided therein and are delimited in a lateral direction by flat field-insulating regions. Vertical npn bipolar epitaxial base transistors are disposed in a first partial number of the active regions while vertical pnp bipolar epitaxial base transistors are arranged in a second partial number of the active regions of the BiCMOS device. One transistor type or both transistor types are provided with both a collector region and a collector contact region in one and the same respective active region. In order to improve the high frequency characteristics, an insulation doping region that is configured so as to electrically insulate the collector and the substrate is provided between the collector region and the substrate exclusively in a first transistor type in which the type of conductivity of the substrate corresponds to that of the collector region. In addition, the collector region of the first transistor type or both transistor types is laterally delimited by the flat field-insulating regions. | 08-20-2009 |

20120029370 | METHOD AND APPARATUS TO DETERMINE THE OVERALL FITNESS OF A TEST SUBJECT - A procedure and apparatus to determine the overall fitness of a test subject. For this purpose the qualitative and temporal progression of the heart rate under constant physical stress of the subject is prescribed with at least one parameter dependent on the subject. The heart rate of the subject is measured under constant physical stress during a period of time. The parameter(s) are determined from the measured values, and the maximum heart rate and/or the initial heart rate and/or the increase characteristic of the heart rate are determined from the function and the measured values by numerical procedures. The apparatus can measure the heart rate of the subject, record a temporal progression of the heart rate under physical stress, and determines numerically from the temporal progression of the heart rate, the maximum heart rate and/or the initial heart rate without physical stress and/or the increase characteristic of the heart rate. | 02-02-2012 |

20100292623 | POLYETHYLENIMINE NANOPARTICLE-CONTAINING MICROBICIDAL ELECTROSPUN POLYMER FIBERS FOR TEXTILE APPLICATIONS - The present invention relates to a process for producing electrospun fibers comprising polyethyleneimine nanoparticles (PEIN). The use of PEIN permits the antibacterial finishing of electrospinnable polymers, provided that these polyethyleneimine nanoparticles are particles of derivatized polyethyleneimine (PEI), since pure underivatized PEI has no antibacterial action. Preference is given to using quaternized polyethyleneimine. The electrospinnable polymers can be coated with PEIN during and/or after the electrospinning. The polymeric fibers obtainable by the process according to the invention can be used for textile fibers, for example for the production of fibers for functional apparel or for fibrous nonwoven webs or fibrous mats for cell culture substrates. | 11-18-2010 |
