Patent number: 9166694Abstract: The invention relates to an optical coupling unit for an arrangement for sending optical signals, including a base unit, a light path formed between a light input and a light output of the base unit and configured to transmit light received via the light input to the light output, an outer light path section included in the light path, which section extends outside the base unit and into which the light transmitted along the light path emerges from the base unit via a light exit and from which the light after passing through the outer light path section enters again into the base unit via a light entry, and a light decoupling element, which is formed in the light path by means of at least one beamsplitting surface coating and configured to decouple a portion of the light transmitted along the light path. Furthermore the invention relates to an arrangement for sending optical signals and to an optical transceiver.Type: GrantFiled: December 20, 2011Date of Patent: October 20, 2015Assignee: FCIInventors: Sven Otte, Kai Schamuhn, Andreas Krink, Juergen Blank, Nicola Iwanowski

Patent number: 8668490Abstract: The invention relates to a method and an arrangement for igniting a gas flow by means of remote control. The aim of the invention is to maintain the current consumption so low that an integratable voltage source can be used. To this end, a thermoelectric safety pilot valve (17) is opened and the escaping gas ignited by the actuation of an electronic control unit (5) fed by a voltage source. Said thermoelectric safety pilot valve (17) is maintained open by a safety pilot magnet (18) by means of a holding current from the voltage source until a thermocouple (22) provides the required holding current once the gas flow has been ignited or a defined holding time is exceeded.Type: GrantFiled: February 11, 2004Date of Patent: March 11, 2014Assignee: Mertik Maxitrol GmbH & Co. KGInventors: Barbara Happe, Jürgen Blank

Patent number: 7919732Abstract: The invention relates to a method and a circuit for igniting a gas flow in a fully automatic manner. The aim of the invention is to maintain the necessary current consumption so low that an integratable voltage source can be used. To this end, once an electronic control unit has been activated, a thermoelectric safety pilot valve (2) is opened by an electromagnet which is temporarily excited by a rush of current, is maintained in the open position by a safety pilot magnet (6) by means of a holding current provided by a voltage source (10), and the escaping gas is ignited. Once a thermoelectric couple (4) is provided for the necessary holding current, the voltage source (10) is switched off. In the event of damage, the method is automatically interrupted.Type: GrantFiled: February 12, 2004Date of Patent: April 5, 2011Assignee: Mertik Maxitrol GmbH & Co., KGInventors: Jürgen Blank, Barbara Happe

Patent number: 7891972Abstract: The aim of the invention is to create a gas regulating fitting which, once a gas stove has been successfully started up, can switch the pilot burner into the off position when the main burner is in the off position, in order to maintain the power consumption of the gas stove as low as possible. The aim of the invention is also to provide the gas regulating fitting with as simple a structure as possible. To this end, the gas regulating fitting comprises a sensor (34) by which means the operating state of the main burner (33) can be detected. The sensor (34) is connected to a thermoelectric safety pilot valve (17) in such a way that, when the operating state of the main burner (33) is switched from the on position into the off position by a signal emitted from the sensor (34), the thermoelectric safety pilot valve (17) assumes the closed position thereof. The gas regulating fitting can be used to ignite and to regulate a gas flow flowing to a burner.Type: GrantFiled: March 10, 2005Date of Patent: February 22, 2011Assignee: Mertik Maxitrol GmbH & Co.

Patent number: 7137061Abstract: A method and a configuration produce a fault signal that is suitable for identifying transmission faults when using differential signaling. A first mid-level signal whose potential is in the area of the mid-point between the signal level on a first signal line and a signal level on a second signal line, when a logic “1” is transmitted is compared with a second mid-level signal formed when a logic “0” is transmitted. The fault signal is produced if the discrepancy between the two mid-level signals is greater than a predetermined threshold value.Type: GrantFiled: August 15, 2003Date of Patent: November 14, 2006Assignee: Infineon Technologies AGInventor: Jürgen Blank

Patent number: 7007145Abstract: A control apparatus and a method for controlling access to a memory in an integrated circuit for an electronic module is provided. The invention includes a memory which is split into a plurality of memory areas which contain data relating to the module. The invention also includes a password register which contains at least one password for the manufacturer of the module and at least one password for a user. An access control means stipulates certain conditions for at least one of the memory areas, such as the extent to which the memory area is readable or writeable, where at least one of the following conditions can be stipulated for portions of a memory area: a memory area is readable when the manufacturer password is input; a memory area is readable when the user password is input; a memory area is readable without a password; a memory area is writeable when the manufacturer password is input; a memory area is writeable when the user password is input; a memory area is writeable without a password.Type: GrantFiled: August 11, 2003Date of Patent: February 28, 2006Assignee: Finisar CorporationInventors: Karl Schrödinger, Jürgen Blank

Patent number: 6956408Abstract: A drive device for a light-emitting component including a reference source, which generates a current specification signal specifying a desired current through the light-emitting component, a current mirror circuit, which generates a current equal to a fraction of the actual current through the light-emitting component, and a regulating device having a first input and a second input, the first input being connected to the current mirror circuit and the second input being connected to the reference source. In this case, the regulating device generates a regulation signal that regulates the current through the light-emitting component in such a way that the deviation between the desired current and the actual current becomes minimal.Type: GrantFiled: January 26, 2004Date of Patent: October 18, 2005Assignee: Infineon Technologies AGInventors: Karl Schrödinger, Jürgen Blank

Patent number: 6647183Abstract: To ensure laser safety, also in the case of a largest possible coupled optical power, during the direct optical coupling of a light-emitted component to an optical waveguide, an optical system includes coupling the light through a fiber end configured as a multimode step index optical waveguide having a numeric aperture larger than the half-width value of the angular distribution of the radiation emitted from the radiation source. To distribute the radiation fed into the actual optical waveguide over the largest possible angular range with regard to the luminous power, the coupling of the light beam into the fiber end is effected such that the coupled light beams are inclined in relation to the geometric axis of the optical core of the fiber end at a defined angle.Type: GrantFiled: July 25, 2002Date of Patent: November 11, 2003Assignee: Infineon Technologies AGInventors: Jürgen Blank, Georg Jeiter, Detlef Kuhl, Volker Plickert, Karsten Drögemüller, Jörg-Reinhardt Kropp, Lars Leininger, Herwig Stange

Patent number: 6512620Abstract: A transmission device contains a plurality of laser transmitters that can be driven individually with a driving current and output optical signals and whose operating point is set via a respective bias current. Each bias current has an individual correction current impressed on it. The correction currents are dimensioned such that, for the same bias current, the laser transmitters have an identical or essentially more uniform average optical output power at the desired operating point.Type: GrantFiled: September 13, 1999Date of Patent: January 28, 2003Assignee: Siemens AktiengesellschaftInventors: Jürgen Blank, Volker Plickert, Torsten Wipiejewski
