Publication number: 20160221228Abstract: A method for the self-assembled production of a topographically surface structured cellulose element. First, a mold is provided having on one side a first surface which is in a complementary manner topographically structured and which is permeable to oxygen. Next, a liquid growth medium containing cellulose producing bacteria is provided. Then, the mold is placed to form a interface such that the side of the mold with the first surface is in direct contact with the liquid growth medium, and an opposite side is facing air or a specifically provided oxygen containing gas surrounding. This allows bacteria to be produced and deposit cellulose on the first surface and developing on the interface a surface structured surface complementary thereto, until a cellulose layer with a thickness of the element of at least 0.3 mm is formed. Finally; the element is removed from the mold.Type: ApplicationFiled: September 18, 2014Publication date: August 4, 2016Applicant: ETH ZÜRICHInventors: Tobias LENDENMANN, Maximilian FISCHER, Simone BOTTAN, Aldo FERRARI, Dimos POULIKAKOS, Bernhard WINKLER, Martin GRAPOW

Patent number: 9343278Abstract: Systems and methods are disclosed for quantitating detectable compounds of a sample. Sample product ion spectra are received for each mass selection window for each time step.

Patent number: 9293531Abstract: A tensile strain state in semiconductor components is adjusted. A pretensioned (tensile strain) layer is applied to a substrate (FIG. 1, (A)). Bridge structures (FIG. 1, (B)) are introduced in the layers by lithography and etching. The bridges are connected to the layer on both sides and are thus continuous. The geometric shape of the bridges, formed with a cross-section modulation, is determined by the windows (FIG. 1 (C)) in the layer. When the substrate is etched selectively, the bridge is undercut through the windows. The geometric structuring of the cross-section (FIG. 1, (D)) causes a redistribution of the originally homogeneous strain when the bridges are detached from the substrate, with the larger cross-sections relaxing at the expense of the smaller cross-sections, where the pretension is increased. Only a multiplication of stresses (or strain) originally present in the sample is possible, with the multiplication factor determined by lengths, widths and depths, and/or the relationships thereof.Type: GrantFiled: May 4, 2012Date of Patent: March 22, 2016Assignees: PAUL SCHERRER INSTITUT, ETH ZUERICHInventors: Jerome Faist, Gustav Schiefler, Hans Christian Sigg, Ralph Spolenak, Martin Süss

Patent number: 9237331Abstract: A closed-loop control system for stereoscopic video capture is provided. At least two motorized lenses are positioned in accordance with specified parameters to capture spatially-disparate images of a scene. The motorized lenses focus light on a corresponding one of the at least two sensors, which generate image streams. One or more processors execute instructions to provide a stream analyzer and a control module. The stream analyzer receives the image streams from the sensors and analyzes the image streams and the specified parameters in real time; the stream analyzer then modifies the image streams and generates metadata. The control module then receives and analyzes the image streams and metadata and transmits updated parameters to a control mechanism that is coupled to the at least two motorized lenses. The control mechanism then modifies operation of the at least two motorized lenses in real time in accordance with the updated parameters.Type: GrantFiled: April 8, 2011Date of Patent: January 12, 2016Assignees: DISNEY ENTERPRISES, INC., ETH ZÜRICH (EIDGENÖESSISCHE TECHNISCHE HOCHSCHULE ZÜRICH)Inventors: Simon Heinzle, Pierre Greisen, Aljoscha Smolic, Wojciech Matusik, Markus Gross

Patent number: 8791410Abstract: A mass spectrometry system based on the general principle of accelerator mass spectrometry (AMS) is disclosed. An ion source (10) generates a beam (B) of ions having a negative charge state. A first mass analyzer (20) transmits only ions having a predetermined mass. The ions are passed through a stripper target (80) comprising helium and/or hydrogen as a stripping gas to change the charge state of said ions from negative to positive charge and to dissociate molecular ions by collisions. A second mass analyzer (110, 130) transmits ions in charge state 1+ having the predetermined mass, which are detected by a detector (140). By using helium and/or hydrogen gas and detecting ions in charge state 1+, it becomes possible to use kinetic energies below 200 keV without excessive transmission losses due to angular straggling. At sufficiently low energies, no additional acceleration is required after ions have been extracted from the ion source.Type: GrantFiled: April 7, 2011Date of Patent: July 29, 2014Assignee: Eth Zürich, Eth TransferInventors: Hans-Arno Synal, Tim Schulze-König, Martin Suter
