Publication number: 20080175536Abstract: An optical two-channel rotary joint that is also suitable for coupling of single-mode fibers comprises two housing parts that are rotatable relative to each other. Each of these housing parts accommodates a light-waveguide for supplying light and a light-waveguide for withdrawing light. The arrangement has two optical paths adapted to operate in opposite directions, with each light-waveguide for supplying light being coupled with a light-waveguide for withdrawing light via an added biconvex lens. Furthermore, one focuser is disposed on each of the light-waveguides for supplying light, which focuses the light of the light-waveguide onto the corresponding light-waveguide for withdrawing light.Type: ApplicationFiled: January 22, 2008Publication date: July 24, 2008Applicant: SCHLEIFRING UND APPARATEBAU GMBHInventor: Nils Krumme

Patent number: 7379503Abstract: A device for receiving digital signals comprising at least one receiving antenna, a measuring means for determining parameters of relevance to signal quality, a digitizer, and a signal-processing unit. The signal-processing unit is controlled to optimize the reception of the digital signals on the basis of the parameters determined by the measuring means. A signal-processing unit processes signals from the receiving antenna and a digitizer converts the processed signals so that the converted processed signals can be measured to determine their relevance signal quality; a transmitter conductor array coupled to the receiving unit can be controlled therefrom. Controlling the signal quality occurs using a dielectric or ferromagnetic materials, impedance elements, or actuators between the receiving antenna and the transmitter conductor array.Type: GrantFiled: September 3, 2003Date of Patent: May 27, 2008Assignee: Schleifring und Apparatebau GmbHInventors: Nils Krumme, Harry Schilling, Georg Lohr
