Patent number: 11073436Abstract: A sensor device including a deflectable membrane made of a 2D nanomaterial, a first optical waveguide for guiding light, disposed adjacent to the membrane and extending along the surface of the membrane at least in a first section, as well as a measuring device for measuring, within the first section the influence of the membrane on an evanescent wave range of the light guided along the first optical waveguide. The influence of the membrane on the light guided in the optical waveguide, in particular on the evanescent wave range of the light, can be measured interferometrically by detecting phasing differences or phase shifts. This allows for a force-free readout of the membrane deflection. By using very thin 2D nanomaterials, the membrane can also react to very quick changes in force.Type: GrantFiled: December 9, 2019Date of Patent: July 27, 2021Assignees: FRAUNHOFER-GESELLSCHAFT zur Förderung der angewandten Forschung e.V., IHP GmbH Leibniz-Institut für innovative MikroelektronikInventors: Giannino Dziallas, Lars Zimmermann, Tolga Tekin, Ha Duong Ngo

Patent number: 6343076Abstract: The spacer has a cell memory, means for allocating a theoretical emission time to each cell, means of control for managing the cell memory, with the aid of an associated pointer memory, in such a way that the cell memory includes, for each virtual connection for which it contains cells, a list of locations where these cells are stored in first-in first-out mode, sorting means for ordering data elements each comprising a virtual connection identity and a sort key consisting of the theoretical time of emission of the cell contained in the start of list relating to said virtual connection, and for selecting at least one data element having a minimum sort key. Each cell emitted is contained in the start of list relating to a virtual connection identified in a data element selected by the sorting means.Type: GrantFiled: May 8, 1998Date of Patent: January 29, 2002Assignee: METInventors: Tuan Ha-Duong, Serafin Soares Moreira

Patent number: 6246686Abstract: When establishing a virtual connection, a pair of identifiers VPI-VCI of Lp+Lc bits is adopted, and data (Id_Cx) relating to said virtual connection is stored in a table in relation to its identifier pair. At the arrival of each ATM cell whose header includes the identifier pair of one of the virtual connections, the data relating to said virtual connection is read from the table. The table includes p.2m storage areas organized as 2m rows and p columns. The data relating to a virtual connection are stored in an area of the table whose row is labelled by an m-bit index calculated by applying a systematic cyclic code, having a generating polynomial of degree m, to a binary word extracted from a sequence of Lp+Lc bits which consists of the bits of one of the identifiers arranged in order of decreasing significance, followed by the bits of the other identifier arranged in order of increasing significance.Type: GrantFiled: February 2, 1998Date of Patent: June 12, 2001Assignee: FihemInventors: Tuan Ha-Duong, Mark Bassham

Patent number: 6181678Abstract: In order to sort data elements each including a sort key, storage means are organized according to a binary tree of 2n−1 nodes which are each able to contain an element and are distributed in n successive stages numbered from 0 to n−1, stage q containing nodes 2q to 2q+1−1. The elements are dispersed within the tree in such a way that each element contained in a node i has a smaller sort key than those of the elements contained in nodes 2i and 2i+1. The trees managed by m successive controllers each associated with a stage or with several consecutive stages of the tree (2≦m≦n), with n−1 interface registers between successive stages, among which those located between the controllers are pipeline registers allowing parallel working of the controllers so as to modify the contents of the tree upon exchange or insertion command propagated from stage 0 to stage n−1.Type: GrantFiled: May 8, 1998Date of Patent: January 30, 2001Assignee: METInventors: Tuan Ha-Duong, Serafin Soares Moreira
