Patent number: 11137320Abstract: The aim of the invention is to economically produce a pressure measuring sensor element, and relates, according to one aspect, to a method for producing a pressure sensor measuring element for a pressure sensor which comprises at least one membrane and a covering protecting the membrane, the pressure sensor element being produced in a layer-by-layer generative production method. This makes it possible to, for example, easily construct a combination sensor for detecting pressure and an additional parameter. It is also possible to structures for reinforcement or for influencing resonant frequency or for influencing heat conduction.Type: GrantFiled: December 7, 2017Date of Patent: October 5, 2021Assignee: Trafag AGInventors: Ulrich Staiger, Daniel Stark, Pahlke Achim, Dieter Zeisel

Patent number: 8984949Abstract: A pressure sensor measuring element for a pressure sensor operates to detect pressure in a combustion space of an internal combustion engine. The pressure sensor measuring element includes a separating diaphragm, a plunger for the transmission of deflections of the separating diaphragm to a force measuring element, and with a sleeve which receives the plunger. The sleeve is closed by the separating diaphragm at a first end intended to face the combustion space and is designed to hold the force measuring element at the opposite second end. Accordingly, the pressure sensor measuring element can be produced more cost-effectively. Furthermore, the plunger can be produced in one piece with the separating diaphragm as a diaphragm/plunger unit, and the sleeve and the diaphragm/plunger unit can be formed from the same metal material.Type: GrantFiled: June 10, 2010Date of Patent: March 24, 2015Assignee: Trafag AGInventors: Ulrich Staiger, Peter Dias-Lalcaca, Peter Hauri, Dieter Zeisel

Patent number: 8079252Abstract: An adapter for pressure sensors for monitoring long-term cylinder pressures in internal combustion engines comprises a housing with a gas duct, a connection to a cylinder cover of an internal combustion engine, a rear opening of the gas duct from the housing with an apparatus for closing this rear opening in a gastight manner, and a connection for inserting a pressure sensor with a sensor membrane. The transition line of the opening in the gas duct, which is reached by the sensor membrane in the inserted state in order to be exposed to the gas pressure in the gas duct, is on a plane. The transition line forms the transition from the contour of the gas duct to the connection to the sensor. There is a continuous transition from the sensor membrane to the contour of the gas duct.Type: GrantFiled: December 5, 2007Date of Patent: December 20, 2011Assignee: Kistler Holding, AGInventors: Alex Weber, Ulrich Staiger, Paul Engeler

Patent number: 8074524Abstract: A piezoelectric measuring element comprises at least one bar with transverse effect which can be used with two conductor technology. Poles comprising the metallizations, electrodes and lines in the measuring element are embodied with one or more piezoelectric bars with transverse effect such that the electric capacitances thereof with respect to the housing are identical. There can be a completely symmetrical design of the poles. A capacitor from one pole to the housing can correspond to the difference in capacitance of both poles to the environment.Type: GrantFiled: May 2, 2007Date of Patent: December 13, 2011Assignee: Kistler Holding, AGInventors: Ulrich Staiger, Paul Engeler, Claudio Cavalloni

Publication number: 20100065013Abstract: The invention relates to an adapter for pressure sensors for monitoring long-term cylinder pressures in internal combustion engines, said adapter comprising a housing 1 with a gas duct 2, a connection 3 to a cylinder cover of an internal combustion engine, a rear opening 11 of the gas duct 2 from the housing 1 with an apparatus 12 for closing this rear opening 11 in a gastight manner, and a connection 4 for inserting a pressure sensor 5 with a sensor membrane 6. The idea underlying the invention is that the transition line 8 of the opening 7 in the gas duct 2, which is reached by the sensor membrane 6 in the inserted state in order to be exposed to the gas pressure in the gas duct 2, is on a plane. The transition line 8 forms the transition from the contour of the gas duct 2 to the connection to the sensor 5. This enables a continuous transition from the sensor membrane 6 to the contour of the gas duct 2.Type: ApplicationFiled: December 5, 2007Publication date: March 18, 2010Applicant: Kistler Holding AGInventors: Alex Weber, Ulrich Staiger, Paul Engeler

Patent number: 5379082Abstract: A method of automatically focusing glass-mounted and glassless slides, permitting quick and reliable focusing as a function of the thickness of the glass mount. According to the invention, the multiple IR radiation images of a mask aperture reflected from glass-mounted slides are focused onto a CCD line sensor. Number and spacings of the images are subsequently electronically detected with respect to their sequence on the CCD line sensor, the second image detected being projected onto a predetermined cell of the line sensor by shifting an autofocusing device and projection lens carrier by means of an electromechanical adjusting apparatus, the cell corresponding to a focused projection image of a glassless slide. Simultaneously, a signal is electronically produced corresponding to the spacing between a first and a second aperture image and cause the projection lens to be shifted by the adjusting apparatus within the autofocusing device carrier by the spacing determined.Type: GrantFiled: September 14, 1993Date of Patent: January 3, 1995Assignee: Eastman Kodak CompanyInventor: Ulrich Staiger

Patent number: 5309329Abstract: The invention relates to a flash device, preferably for transferring a dye matrix which by means of a high-energy light flash is transferred from a radiation-absorbing carrier film by interleaving a mask onto a receiver element. This requires substantially perpendicular irradiation of the transfer plane with a high-energy radiation and a high uniformity of irradiance distribution of the light flash. To achieve this, one or two linearly extending plasma discharge tubes are provided which to concentrate radiation are enclosed by two separate aspheric-cylindrical reflectors, the concentrated radiation being directed through a lamellar louver element arranged downstream of the reflector and impinging on the predetermined transfer plane in a substantially parallel and perpendicular manner.Type: GrantFiled: September 9, 1992Date of Patent: May 3, 1994Assignee: Eastman Kodak CompanyInventors: Reinhold Thiel, Ulrich Staiger, Olaf Kosanke, Volker Gericke

Patent number: 5204820Abstract: A vehicular headlight, in particular an automobile headlight, including a reflector (1) having a reflecting surface, is capable of illuminating a flat target surface to be illuminated with a desired light distribution by optimal utilization of the light source of the headlight. Therefore the optically effective surface of the headlight is characterized by point asymmetry in substantially all planes cutting said reflecting surface. This can be realized by using a method for producing said optical surface comprising the steps of:mathematically representing said surface by creating a spline from bivariate tensor product of polynomials; deriving mathematical data in computer input format from said mathematical representation; and inputting said data to a computer for controlling an apparatus by which the mathematical representation of said optical surface is reproduced in physical form.Type: GrantFiled: October 24, 1991Date of Patent: April 20, 1993Assignee: Eastman Kodak CompanyInventors: Joseph R. Strobel, Ulrich Staiger, Peter E. Castro
