Patent number: 9021882Abstract: An ultrasound-based measuring device includes a measurement body, at least one ultrasonic transmitter for coupling ultrasonic measurement signals into the measurement body, and at least one ultrasonic receiver for detecting the ultrasonic measurement signals reflected at an end face of the measurement body. The at least one ultrasonic transmitter emits both a longitudinal and a transverse measurement signal. The influence of a physical disturbance variable on the measurement section traversed by the measurement signals during a determination of a measurement pressure prevailing at the end face and/or of a measurement temperature prevailing at the end face can be taken into account on the basis of the propagation times and a difference between the propagation times of the longitudinal and transverse measurement signals reflected at the end face.Type: GrantFiled: December 18, 2011Date of Patent: May 5, 2015Assignee: Robert Bosch GmbHInventors: Frank Schatz, Juergen Graf, Gottfried Flik, Georg Bischopink, Fabian Henrici

Publication number: 20040237658Abstract: A method for manufacturing a micromechanical pressure sensor and a pressure sensor manufactured using this method. The pressure is measured in the pressure sensor composed of at least two components via a capacitance measurement of a capacitor, the pressure sensor having at least one first electrode and one first diaphragm. The movement of the diaphragm causes a change in the capacitance of the capacitor which may be used in the capacitance measurement as a measure for the pressure variable to be measured. It is important that, prior to assembly, the first and the second components of the pressure sensor be processed separately. The first component has at least one semiconductor material and the first electrode, whereas the second component is made of metal, at least in part, and contains at least the first diaphragm.Type: ApplicationFiled: March 26, 2004Publication date: December 2, 2004Inventors: Torsten Ohms, Gottfried Flik, Gilbert Moersch, Oliver Stoll

Patent number: 6784792Abstract: A method of deciding with a high reliability whether an impact with the front side of a vehicle has been caused by a pedestrian is described. Two decision criteria are formed, and only if both decision criteria are met is it decided an impact with a pedestrian has occurred. The first decision criterion is determined by the fact that the pressures or deformations measured by a sensor on the bumper and a sensor in the area of the front edge of the engine hood are compared with reference quantities typical of impact with a pedestrian. The second decision criterion is determined by the fact that the changes in velocity and/or acceleration of the vehicle caused by an impact are determined, and then the changes in velocity and/or acceleration are compared with reference quantities which are typical of impact with a pedestrian.Type: GrantFiled: July 1, 2002Date of Patent: August 31, 2004Assignee: Robert Bosch GmbHInventors: Bernhard Mattes, Gottfried Flik

Patent number: 6695229Abstract: A swirl disk is composed of at least one metallic material, and is configured as having at least one intake area and at least one outlet orifice, the at least one outlet orifice being introduced in a lower base layer, and having at least two swirl channels emptying into a swirl chamber, the swirl chamber being provided in a central swirl-producing layer. An upper layer is configured as a cover layer, which over its entire cross-sectional surface represents a closed layer without orifice contours. All the layers of the swirl disk are directly built up on top of each other using electroplating metal deposition (multilayer electroplating). The swirl disk is suitable for a use in a fuel injection valve, in particular in a high-pressure injection valve for directly injecting the fuel into a combustion chamber of a mixture-compressing, external-ignition internal combustion engine.Type: GrantFiled: July 27, 2001Date of Patent: February 24, 2004Assignee: Robert Bosch GmbHInventors: Petra Heinbuch, Frank Schatz, Armin Glock, Ralf Trutschel, Gottfried Flik, Guenter Dantes, Detlef Nowak, Joerg Heyse, Thomas Schittny, Juergen Hackenberg, Ronald Glas
