Publication number: 20150208478Abstract: A method is provided for improving the illumination of an illuminated area (100), especially an operating area, of an illuminating device (10) with at least two light modules (20). The method includes the emission of an illuminant characteristic of the light module (20) with a preset amplitude from each light module (20). The reflected amplitudes of all characteristic light types are detected. The detected amplitudes for each light module (20) are compared. The light intensity of at least one light module (20) is varied on the basis of the comparison of the detected amplitudes for each light module (20).Type: ApplicationFiled: July 8, 2013Publication date: July 23, 2015Applicant: Dräger Medical GmbHInventors: Frank Sattler, Livio Fornasiero, Hartmut Stark

Patent number: 9035555Abstract: A medical lighting device has an operating area light (100), a central control station (11), a lighting control unit (7), a control unit (39), an image detection element (27), an image processing unit (29), reference elements (67, 69), an operating unit (200), a position sensor (25), an operating element (33) arranged at a handle (31), a marking and distance detection element (35) and a device for data transmission (13, 15, 17, 19, 21, 26, 28). A horizontal-vertical position (58) of the operating unit (200) in the room and a light marking position (38) on a reclining surface (99) are determined by the position sensor (25), the marking and distance detection element (35), the image detection element (27) combined with reference elements (67, 69) and image processing unit (29). The operating area light (100) is actuated such that an illuminated area (71) is illuminated on the reclining surface.Type: GrantFiled: September 23, 2011Date of Patent: May 19, 2015Assignee: Dräger Medical GmbHInventors: Livio Fornasiero, Maral Haar

Patent number: 8649012Abstract: An optical gas sensor with a light-emitting diode (2), a photosensor (8), a measuring section between the light-emitting diode and the photosensor, and a control and analyzing unit (16), which is set up to determine the concentration of a gas in the measuring section from the light intensity measurement by the photosensor. The control and analyzing unit (16) is set up to measure the forward diode voltage over the light-emitting diode at a constant current, to determine the temperature of the light-emitting diode from the detected forward diode voltage over the light-emitting diode by means of a preset temperature dependence of the forward diode voltage, and to apply a correction function as a function of the light-emitting diode temperature determined, with which the measurement is converted to that of a preset temperature of the light-emitting diode.Type: GrantFiled: January 8, 2013Date of Patent: February 11, 2014Assignee: Dräger Safety AG & Co. KGaAInventors: Udo Beckmann, Livio Fornasiero

Patent number: 8199326Abstract: A gas concentration-measuring device makes it possible to measure gas components in a gas sample. An interferometer, based on a dual-band Fabry-Perot interferometer (1), is provided with a transmission spectrum that can be set by a control voltage (38). The control voltage (38) of the dual-band Fabry-Perot interferometer (1) is synchronized over the course of time with the activation and deactivation of the radiation sources (11, 12).Type: GrantFiled: January 19, 2010Date of Patent: June 12, 2012Assignee: Drägerwerk AG & Co., KGaAInventors: Peter Dreyer, Günter Steinert, Alfred Kelm, Christian Jäger, Livio Fornasiero, Hartmut Stark, Ralf Buchtal, Burkhard Stock, Ralf Döring, Anja Künzel, legal representative

Patent number: 8050547Abstract: A device and a process are provided for uniformly lighting an operating area for performing the lighting of an operating area (2) of a bed (30) by means of a lighting unit (3) such that a selected lighting field (13) is lighted uniformly. The image signals of a camera (7) are sent to an image processing unit (17), in which the image signals are analyzed and the individual lighting elements (6) are switched via the control unit (18). A lighting situation is acquired in the process for initializing and operating this lighting system and a lighting field (13) of interest is selected. The image signals are analyzed during the operation and sent to the control unit (18) in order to switch the lighting elements (6) such that uniform lighting is obtained in the first lighting field (13).Type: GrantFiled: April 6, 2009Date of Patent: November 1, 2011Assignee: Dräger Medical GmbHInventor: Livio Fornasiero

Patent number: 6765661Abstract: The invention enables more objective defect evaluation of ophthalmic lenses, especially contact lenses, to take place through the combination of the schlieren method with the transmitted light method, with the result that the advantages of these two different systems are combined. The schlieren method is in a position to illustrate the edge of a contact lens and its ruptures, in high contrast, for the CCD camera. Likewise, tears and surface defects can be made visible. Using the transmitted light method, the bubbles may be suitably prepared for the camera.Type: GrantFiled: March 6, 2002Date of Patent: July 20, 2004Assignee: Novartis AGInventors: Roger Biel, Joachim Linkemann, Livio Fornasiero, Ingolf Braune
