Patent number: 8167071Abstract: An engine hood for a motor vehicle has an outer planking and an inner part. Between the outer planking and the inner part, a supporting part is arranged, which reinforces the outer planking. In order to reduce the manufacturing costs for an engine hood while maintaining a favorable delay pattern in the event of a head impact, the supporting part has supporting elements which, in the event of an essentially vertical admission of force, permit a displacement of the outer planking relative to the inner part until the supporting part rests with its predominant surface against the inner part.Type: GrantFiled: November 7, 2008Date of Patent: May 1, 2012Assignee: Dr. Ing. h.c.F.

Publication number: 20090175546Abstract: In a method and apparatus for dynamics compression in images or signal series represented by individual amplitude values, input amplitude values EA of the images or signal series are subjected to a local spatial amplitude averaging, to generate locally spatially averaged input amplitude values <EA>. Differential function values are then formed based on differences between the input amplitude values EA and the locally spatially averaged input amplitude values <EA>, and output amplitude values AA of the images or signal series are generated from the formed differential function values. In forming the differential function, additional differential values are superimposed on the differences formed from the input amplitude values EA and the locally spatially averaged input amplitude values <EA>, which additional differential values are formed from the input amplitude values EA and a predefined reference value GA.Type: ApplicationFiled: March 7, 2007Publication date: July 9, 2009Applicant: EADS Deutschland GmbHInventors: Willi Platz, Gerald Sobotta, Dieter Wolf

Patent number: 5935405Abstract: Rigid or flexible circuits of electrically conductor tracks can be produced on flexible or rigid, non-conductive support materials bya) coating the surfaces of the support materials including existing drill holes with a primer and a conductive polymer, preferably poly-3,4-ethylendioxythiophene, which may contain binders,b) applying an electroplating resist in the form of the negative image of the conductor tracks,c) metallizing by electroplating the surface kept free by the electroplating resist, including existing drill holes, in the form of the positive image of the conductor tracks,d) removing the electroplating resist ande) removing the conductive polymer, which had been below the electroplating resist, or converting it to a non-conductive form, wherein the conductor tracks are electrically interconnected during the metallizing step by the layer of conductive polymer, thereby avoiding the need to individually contact each conductor track.Type: GrantFiled: September 9, 1997Date of Patent: August 10, 1999Assignee: Bayer AktiengesellschaftInventors: Gerhard-Dieter Wolf, Friedrich Jonas

Patent number: 5333591Abstract: A device to control a gas-fired appliance as a function of the composition of a gaseous fuel. The device includes a thermal conductivity sensor emitting a measurement signal dependent upon the thermal conductivity of the gaseous fuel. An analyzing unit receives the measurement signal and uses it to develop a control signal dependent upon the composition of the gaseous fuel. A control unit receives the control signal and uses it to control the operating parameters of the gas-fired appliance, in the case of a gas engine particularly the parameters of air/fuel ratio, output and angle of advance. The analyzing unit may include an input interface into which data on the type of gaseous fuel components may be entered, which are used for the generation of the control signal. Preferably the control signal is proportional to the available methane number of the gaseous fuel, whereby the operating parameters of the gas engine are controlled so that the methane number required is adjusted to the methane number available.Type: GrantFiled: March 10, 1993Date of Patent: August 2, 1994Assignee: Ruhrgas AktiengesellschaftInventors: Wilhelm Korsmeier, Dieter Wolf, Manfred Hoppe, Holns J.
