Patent number: 7635834Abstract: Systems and method for optically imaging objects and in particular optical patterns or codes onto a detection device by a pinhole aperture are described. According to an embodiment of the invention these systems have optical attenuation elements between the illumination devices and the object which substantially compensate the system-inherent imaging detects caused by the pinhole aperture and in particular the system-inherent peripheral decrease in brightness of an image of the object formed by a pinhole aperture on the detection device. According to an embodiment of the invention, the optical attenuation elements change the illumination intensity of the object in such a manner that the central areas of the object are illuminated at a lower light intensity than its peripheral areas. As a result of the subsequent imaging of the object by a pinhole aperture, the central areas of the object are imaged onto the detection device at a higher light intensity than the peripheral areas of the object.Type: GrantFiled: July 3, 2007Date of Patent: December 22, 2009Assignee: Roche Diagnostics Operations, Inc.Inventors: Manfred Augstein, Joerg Dreibholz, Dieter Falk, Uwe Kass, Heinz Macho

Patent number: 6258531Abstract: A method of isolating a biological material by a) providing a biological material which is bound to a porous matrix (C11), and b) compressing the matrix under conditions where the biological material is released from the surface of the matrix into an elution liquid. brings about the advantage that the emission of aerosols into the environment is greatly reduced. It is also possible to obtain highly concentrated and minute amounts of solution. The method is also easy to automate.Type: GrantFiled: March 26, 1996Date of Patent: July 10, 2001Assignee: Roche Diagnostics GmbHInventors: Gerhard Bienhaus, Michael Fritz, Jürgen Schwab, Edda Geisler, Herbert Harttig, Heinz Macho

Patent number: 6024138Abstract: Dispensing device for dispensing small quantities of fluid comprising a compressible balloon with an end-to-end capillary inserted within the walls of the balloon in such a way that the one end of the capillary communicates with the interior of the balloon and the other end of the capillary communicates with the exterior space. The balloon has at least one opening through which the interior space of the balloon communicates with the exterior space. The at least one opening has a flow resistance that is designed so that a fluid contained in the capillary is expelled when the balloon is compressed. The present invention also comprises a system and method for the metered dispensing of fluids.Type: GrantFiled: April 17, 1998Date of Patent: February 15, 2000Assignee: Roche Diagnostics GmbHInventors: Michael Fritz, Heinz Macho, Helmut Rinkel, Jurgen Schwab, Georg Arras, Klaus Oswald, Alfred Schaffner

Patent number: 4592893Abstract: An analysis test strip and a process for the production of analysis test strips with a longitudinal carrier upon which is fixed at least one test field. The test field material is produced batchwise in an amount sufficient for a plurality of test strips, and thereafter, in a chronologically separate working step, is continuously fixed in the form of at least one band onto a parallel-running substantially wider band of test strip carrier material. The band as a whole is cut up transversely to its longitudinal direction into a plurality of test strips. Prior to the cutting up, a bar code is applied to the carrier band running parallel to the edges thereof of such high information density that it is suitable as a store of batch-specific information necessary for the quantitative evaluation of the reaction which has previously been obtained by investigation of the test field material of one batch.Type: GrantFiled: May 8, 1984Date of Patent: June 3, 1986Assignee: Boehringer Mannheim GmbHInventors: Werner Poppe, Rainer van Rijekevorsel, Uwe Ruppender, Heinz Macho
