Publication number: 20240166910Abstract: A photonic device including a first waveguide and a second waveguide is provided. The device includes an interconnect coupled with the first waveguide and the second waveguide. The interconnect includes a substrate. The interconnect includes a film including a refractive index contrast (RIC) polymer and a core. The core includes a first domain having a first refractive index. The core includes a second domain adjacent to the first domain and having a second refractive index. The second refractive index is less than the first refractive index. The core includes a third domain adjacent to the second domain and having a third refractive index. The third refractive index is less than the second refractive index. The second domain is disposed between the first domain and the third domain. The refractive index of the substrate is less than the first refractive index, the second refractive index, and the third refractive index.Type: ApplicationFiled: April 8, 2022Publication date: May 23, 2024Applicant: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Robert Norwood, Dong-Chul Pyun, Stanley Pau, Roland Himmelhuber, Linan Jiang, Thomas Koch, Kyungjo Kim, Sasaan Showgi, Tristan Kleine, Abhinav Nishant, Julie Frish

Publication number: 20170243851Abstract: The invention relates to an apparatus for especially thermally joining micro-electromechanical parts (2, 3) in a process chamber (8), comprising a bottom support plate (11) for holding at least one first (2) of the parts (2, 3) to be joined, and a pressing device (15) for applying pressure to at least one second (3) of the parts (2, 3) to be joined in relation to the at least one first part (2). The pressing device (15) is equipped with an expandable membrane (19) provided for entering in contact with the at least one second part (3). Fluid pressure, in particular gas pressure, can be applied to said membrane (19) on the side thereof facing away from the parts (2, 3) to be joined.Type: ApplicationFiled: August 14, 2015Publication date: August 24, 2017Applicant: ATV TECHNOLOGIE GMBHInventors: Ventzeslav RANGELOV, Siegfried KOWALSKY, Walter PORT, Roland KOCH

Patent number: 8790094Abstract: A diaphragm vacuum pump has an electrically operated drive unit and a vacuum diaphragm, which separates a pump chamber into a drive-side part and a drive-remote part and which can be deflected by means of a movable part of the drive unit. The drive unit is an electromagnetic drive unit and the vacuum diaphragm is deflected in the direction of a linear movement generated electromagnetically in the drive unit. Preferably, a ventilation valve is also actuated the movable part. The vacuum pump is relatively small and compact and operates quietly. The vacuum pump is suitable in particular for “hands-free” applications of breastpumps.Type: GrantFiled: September 15, 2011Date of Patent: July 29, 2014Assignee: Medela Holding AGInventors: Armin Felber, Beda Weber, Roland Koch, Etienne Furrer

Patent number: 7389632Abstract: Small objects are loaded into blisters of a passing packaging film in a fill station of a packaging machine. An apparatus for distributing the objects to the blisters has a pair of generally parallel rods extending along respective axes and having inner and outer ends. Respective guides support the rods for movement parallel to their axes, and a bar extends transversely between the outer ends. An actuator mechanism periodically synchronously rotating the rods. Respective couplings between each of the outer ends and the bar transversely shifting the bar relative to the rods on rotation of the rods.Type: GrantFiled: June 11, 2007Date of Patent: June 24, 2008Assignee: Uhlmann Pac-Systeme GmbH & Co. KGInventors: Martin Seiffert, Harald Litke, Diana Zugenmaier, Roland Koch

Patent number: 7285960Abstract: A device and a method for locating partial discharges in a conductor rod of a dynamo-electric machine are provided, the conductor rod being provided with an exterior electrical insulation. A first and a second sensor are embodied so as to detect a signal which is generated by the partial discharge and spreads along the conductor rod. The first and second sensor are disposed at a distance from each other on the conductor rod in order to emit a partial discharge output signal that represents a specific moment of detection. The partial discharge output signals of the first and second sensor are fed to an evaluation unit which is embodied so as to locate the partial discharge on the conductor rod.Type: GrantFiled: April 19, 2004Date of Patent: October 23, 2007Assignee: Siemens AktiengesellschaftInventors: Roland Koch, Jürgen Weidner

Patent number: 4500764Abstract: Apparatus for internal welding of pipes is provided with an external mechanism for rotating a pipe to be treated and a car insertable into the pipe and operable within the pipe. The car which carries a welding equipment is rigidly mounted to a central shaft which is freely pivotally mounted by means of bearings in two subframes each of which carries a number of tread rollers which can be locked against the inner surface of the pipe, so that the subframes during the operation are rotated together with the pipe whereas the car hangs downwardly within the pipe.Type: GrantFiled: August 9, 1983Date of Patent: February 19, 1985Assignee: VEB Gaskombinat Schwarze PumpeInventors: Erich Girodi, Gunter Bornowski, Eberhard Dejmek, Andreas Knabe, Roland Koch, Bernd Urbach, Arnold Weisselberg
