20090260597 | FUEL INJECTOR AND FUEL-INJECTION SYSTEM - A fuel injector, especially for the direct injection of fuel into a combustion chamber of an internal combustion engine, includes a nozzle body able to be inserted into a recess of a cylinder head, a valve housing, a plug abutting the valve housing, and at least one fixation element, which fixes the nozzle body in its position in the recess, the fixation element extending from a connection region ( | 10-22-2009 |
20130062441 | Fuel Injector - The fuel injector provides an oncoming flow, that is uniform and stable in time, of the spray-discharge orifices is produced and consequently, and a reduction in variance in the spray and flow-through characteristics variables. The fuel injector includes at least one excitable actuator and a valve element that is movable along a longitudinal valve axis, which collaborates in a sealing manner with a valve seat. Upstream of the valve seat, circumferentially a plurality of flow-through regions are provided, between which there are guidance regions for the valve element. The spray-discharge orifices downstream from the valve seats, whose number differs from the number of the flow-through regions, discharge the fuel finely atomized. At least two flow-through regions differ in size, such as circumferential width and/or radial depth, and/or contour. The fuel injector directly injects fuel into a combustion chamber of an engine using compression of a fuel/air mixture and spark ignition. | 03-14-2013 |
20150013644 | DECOUPLING ELEMENT FOR A FUEL INJECTION DEVICE - A decoupling element for a fuel injection device has a low-noise construction. The fuel injection device includes at least one fuel injector and one receiving bore in a cylinder head for the fuel injector and the decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element has a nonlinear progressive spring characteristic as a solid-state joint, at least one bearing collar including a valve contact surface, which is designed to be spherical, i.e., convex, extending upward from a flat annular area, the flat annular area being supported on a supporting base, and the inside of the annular area has a smaller inside diameter D than the bearing collar and the supporting base, which is supported on the wall of the receiving bore. | 01-15-2015 |
20150090913 | Valve for metering fluid - A valve for metering fluid is reported which has a valve housing having a valve opening and a valve seat, a valve needle, which is provided for the alternating closing and opening of the valve using a closing member cooperating with the valve seat, a resetting element that acts on the valve needle for closing the valve and an electromagnet that is able to have current applied to it, having a magnet armature that is drivable to a lift motion, which sits axially displaceably on the valve needle and carries along the valve needle in the lift direction for opening the valve via a driving flange situated on it. To simplify production and the assembly of the valve while achieving the advantages characteristic in valves having a prestroke spring and an armature free path, the magnet armature is supported on the valve housing using a diaphragm spring. | 04-02-2015 |

20100067621 | Feed Forward Detector for Pattern Dependent Noise Prediction - Various embodiments of the present invention provide systems and methods for processing data. As one example, a circuit is disclosed that includes a digital input signal that is provided to a pre-detector that detects an estimated pattern in the digital input signal. In addition, the digital input signal is provided to a summation element that subtracts the estimated pattern from the digital input signal to yield a noise estimate. The noise estimate is provided to a data dependent noise prediction filter that is statically tuned to detect a highly correlated noise pattern, and provides a filtered noise estimate. In some cases, the circuit further includes a post-detector that performs a data detection process on the digital input signal reduced by the filtered noise estimate. | 03-18-2010 |
20100067628 | Adaptive Pattern Dependent Noise Prediction on a Feed Forward Noise Estimate - Various embodiments of the present invention provide systems and methods for processing data. As one example, a circuit is disclosed that includes a pre-detector that detects an estimated pattern in a digital input signal, and a summation element that subtracts the estimated pattern from the digital input signal to yield a noise estimate. The circuit further includes a data dependent noise prediction filter that is adaptively tuned to detect a noise pattern, and that filters the noise estimate to provide a filtered noise estimate. | 03-18-2010 |
20120107921 | MODEL BASED CONTROLS FOR USE WITH BIOREACTORS - Embodiments of the present invention include model-based controls to control photobioreactor operation and the growth of algae for use as a biofuels feedstock. In some embodiments, the model-based control can accounts for future conditions such as weather, product pricing, customer demands and/or other variables to operate the reactors in a manner that optimizes product revenues, minimizes costs or energy, maximizes photosynthetic or energy balance efficiency, and/or any combination of the aforementioned factors. | 05-03-2012 |
