Patent number: 7486394Abstract: A measuring head (4) according to the invention comprises the combination of a zone lens (26), which is preferably a diffractive lens, with a hemispherical lens (23) or a GRIN lens (33). This represents a concept capable of miniaturization, resulting in very slender measuring heads (4) having a high numeric aperture and, accordingly, leads to the best resolution capacity. Such measuring heads are insensitive to angular errors as concerns the orientation of the measuring head to the surface to be measured or to an oblique positioning of the surface relative to the optical axis of the measuring head.Type: GrantFiled: September 2, 2006Date of Patent: February 3, 2009Assignee: Carl Mahr Holding GmbHInventors: Peter Lehmann, Peter Lücke, Jürgen Mohr, Carlos Javier Moran-Iglesias, Wolfgang Osten, Aiko Ruprecht, Sven Schönfelder

Patent number: 7483150Abstract: A measuring device (1) for measuring the shape, contour and/or roughness of a workpiece is based on a contact-less optical probe having a large numeric aperture. The probe has at least two different focal points with which at least two photo receptors are associated. The latter generate a differential signal for controlling a positioning device (13) for tracking the optical probe in such a manner that the workpiece surface is maintained within the measuring range of the probe. The differential signal is proven to result in a rapid and accurate tracking of the position of the sensor arrangement (3).Type: GrantFiled: April 20, 2005Date of Patent: January 27, 2009Assignee: Carl Mahr Holding GmbHInventor: Peter Lehmann

Patent number: 7287748Abstract: A method and apparatus for producing selectively collated print products employ a production section, a control device, a transfer-out device for transferring out defective print products, a detection device that detects and records gaps resulting from the transfer out of defective print products, and a transfer-in device. Initially, a line of print products are processed in a production section; a predetermined number of print products are diverted from the production section and supplied to a product buffer. If the print products are not diverted, the line of print products continue in a conveying section and gaps between the print products are detected and recorded via the detection device. A number of print products are removed from the product buffer based on a control signal from the control device to fill detected gaps between print products in the conveying section; and the removed print products are inserted into the recorded gaps.Type: GrantFiled: October 14, 2004Date of Patent: October 30, 2007Assignee: Müller Martini Holding AGInventors: Rémy Maeder, Peter Lehmann

Publication number: 20070165240Abstract: An interferometric measuring method for detecting shapes is based on the interferometric observation of an object surface subjected to narrow-band lighting. A movement of the interferometer (1) relative to the object surface (2) generates a measuring signal on a suitable photo receiver, for example a camera circuit (5), from which two extremely closely positioned signal frequencies (f0) and (f0+?f) are extracted. The phase difference between the two signal components is used for determining the distance and/or the change in the distance. The method has a large unambiguousness range, thus making it possible to have a large depth measurement range. The method can also be used for workpieces having offset areas on the surface, wherein the measurement is not disturbed along the edges and the offset areas of the body.Type: ApplicationFiled: May 25, 2005Publication date: July 19, 2007Applicant: CARL MAHR HOLDING GMBHInventor: Peter Lehmann

Publication number: 20070148704Abstract: The present invention relates to a method aiding in the assessment of rheumatoid arthritis. The method especially is used in the differential diagnosis of rheumatoid arthritis in vitro. The method is for example practiced by analyzing biochemical markers, comprising measuring in a sample both the concentration of anti-CCP and of antinuclear antibodies (ANA) correlating the concentrations determined to the diagnosis of rheumatoid arthritis. To further improve the assessment of RA in a method of this invention the level of one or more additional marker may be determined together with anti-CCP and ANA and be correlated to the absence or presence of RA. The invention also relates to the use of a marker panel comprising anti-CCP and ANA in the diagnosis of rheumatoid arthritis and it teaches a kit for performing the method of the invention.Type: ApplicationFiled: October 3, 2006Publication date: June 28, 2007Inventors: Ursula Klause, Hans-Peter Lehmann, Iris Fuehling, Susanne Schmolke, Werner Zolg

Publication number: 20070035744Abstract: The apparatus according to the invention comprises an object lens which can operate in at least two different measuring modes. In a first, interference mode a workpiece is measured by means of interference optometry. In a second, imaging measuring mode an optical image is produced, for example, on a camera-like detector array and may be applied to an image processing routine. Switching between the two measuring modes is performed by the type of illumination of the object lens and an element which is disposed preferably in the reference beam path of an interferometer and which activates or deactivates the reference beam path dependent on the spectral composition of the utilized light. In this manner a simple and rapid changeover between the two measuring modes is provided, without the need for replacing or even for moving the object lens.Type: ApplicationFiled: October 24, 2006Publication date: February 15, 2007Inventors: Peter Lehmann, Norbert Steffens

Publication number: 20060286681Abstract: The present invention relates to a method for establishing a diagnosis if an individual has suffered from or a prognosis if an individual is at risk of suffering from a coronary heart event, which method comprises determining the concentration of sCD40L in a body fluid of the individual; determining the concentration of a proximal inflammatory marker, preferably PAPP-A or Lp-PLA2 comparing the values obtained with reference values; and establishing the diagnosis or the prognosis in respect to the cardiovascular event. The combination according to the invention can be used with further markers selected from further inflammatory markers, anti-inflammatory markers and/or neurohumoral markers.Type: ApplicationFiled: May 8, 2006Publication date: December 21, 2006Inventors: Hans-Peter Lehmann, Iris Fuehling, Charles Cant, Klaus Hallermayer

Patent number: 6418591Abstract: The present invention relates to a tightening fastener, in which a clip band is bent in the shape of a ring or a spiral, as well as a tension locking system, wherein the clip band can be used to fasten elongated objects such as cables or pipes in pipeworks and mainly pipes which cannot be accessed. A series of radially protruding holders may be attached to the clip band. These holders are positioned to receive cables, pipes, or other elongated objects. The tension locking system may include a stop member which can, for example, be made in the shape of a stop bolt and which may be maintained in a stop position by a stop frame. When the stop bolt is disengaged from its stop position, the tension locking system partially expands and transmits the tightening force to the clip band, thus tightening the clip band.Type: GrantFiled: October 31, 2000Date of Patent: July 16, 2002Assignees: KA-TE System AGInventors: Reinhard Hecht, Karl Manstorfer, Peter Lehmann, Heinz Maag, Hans Wyder, Hans Bunschi, Marco Weingarten
