Patent number: 10644759Abstract: The invention relates to a mobile communication system. The mobile communication system includes a first base station configured to transmit at least part of a first data set of data segments arranged in a first sequence to a user terminal, and a second base station configured to transmit at least part of the first data set of data segments arranged in a second sequence to the user terminal, the second sequence of the first data set being an inverse of the first sequence of the first data set. The invention also relates to a coordination component, base station and user terminal for use in this system and to a method of arranging data segments in sequences performed by the coordination component. The invention further relates to a method of transmitting an acknowledgement, performed by the base station or by the user terminal.Type: GrantFiled: December 14, 2016Date of Patent: May 5, 2020Assignees: KONINKLIJKE KPN N.V., NEDERLANDSE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK TNO, UNIVERSITY OF TWENTEInventors: Berksan Serbetci, Jasper Goseling, Ljupco Jorguseski

Publication number: 20200108391Abstract: The present invention describes a method and device for improving the capture and interrogation of a rare cell population in a biological fluid such as in circulating tumor cells (CTC) in blood or Diagnostic Leukapheresis. ReFLECT-CTC is designed to capture CTC in a continuous fashion and interrogate isolated individual CTC. ReFLECT-CTC has the advantage of sampling large volumes of a biological sample which is especially useful in assessing the heterogeneity of a CTC population. The invention has application in cancer diagnostics where assessing tumor cells found in individual cancer patients will determine which drugs are most likely to be effective for an individual.Type: ApplicationFiled: April 13, 2018Publication date: April 9, 2020Applicant: University of TwenteInventors: Michiel Stevens, Arjan G.J. Tibbe, Joska Johannes Broekmaat, Frederic Thomas NIJSINK, Leon W.M.M. Terstappen, Guus van Dallum

Publication number: 20200016591Abstract: The present invention discloses a device and methods for the analysis of secreted molecules from a single cell. As described herein, the invention incorporates individual microwells with a bottom surface capable of capturing a cell and allows the release of secreted molecules to be printed onto a capture surface. The device provides accurate identification of the cell source of the printed molecules by mapping the printed molecules to the cell source. The invention further employs spectrometry, immunoassay or label free Surface Plasmon Resonance imaging for detection of the secreted molecules in combination with a microwell array, where single cells are seeded in individual microwells and the secreted molecules are captured by the capture surface in an array print while the cell remains in the microwell for additional interrogation. The present invention has applications in medical research and diagnosis where individual target cells in a fluid sample are interrogated for the secreted products.Type: ApplicationFiled: December 14, 2017Publication date: January 16, 2020Applicant: University of TwenteInventors: Richard Schasfoort, Arjan Tibbe, Joska Johannes Broekmaat, Fikri Abali, Leon WMM Terstappen

Patent number: 10219118Abstract: The disclosure relates to a transmission node and a method for wirelessly providing a number of data packets to a plurality of receivers in a cell of a transmission node of a cellular telecommunications system. The method comprises the steps of storing a number of network coded data packets at the transmission node and cyclically transmitting the stored network coded data packets from the transmission node to the plurality of receivers. The number of transmitted network coded data packets in a cycle is at least equal to the number of data packets to be provided to each receiver of the plurality of receivers and each network coded data packet is a linear combination of two or more data packets to be provided to each receiver.Type: GrantFiled: December 14, 2016Date of Patent: February 26, 2019Assignees: KONINKLIJKE KPN N.V., NEDERLANDSE ORGANISATE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK TNO, UNIVERSITY OF TWENTEInventors: Jasper Goseling, Ljupco Jorguseski

Patent number: 9455689Abstract: A Silicon On Insulator current source array includes input control for receiving a control voltage, a first reference input for receiving a first reference voltage, and a second reference input for receiving a second reference voltage. A chain of several Silicon On Insulator MOS transistors, of the same type, have control electrodes all connected to the input control, first conduction electrodes are all connected to the first reference input, and second conduction electrodes are respectively connected to the second reference input through several load circuits respectively configured to be traversed by several currents when the several transistors are ON upon application of the control voltage on the input control. An input bias is coupled to a semiconductor well located below an insulating buried layer located below the chain of transistors for receiving a biasing voltage difference.Type: GrantFiled: November 19, 2014Date of Patent: September 27, 2016Assignees: STMICROELECTRONICS SA, UNIVERSITY OF TWENTEInventors: Andreia Cathelin, Bram Nauta

Publication number: 20140341874Abstract: The invention relates to a dextran-based tissuelette comprising platelet-rich plasma lysate (PRPL), which can be used for tissue repair. In particular, the tissuelette of the present invention can be adapted to display properties similar to natural cartilage, while having increased chondrocyte-attraction. Also, it has a tunable biostability that allows for degradation of the tissuelette material during natural tissue regeneration. In addition, the tissuelette displays full and covalent integration with the surrounding tissue when prepared directly at the site requiring tissue repair. The tissuelette of the present invention is primarily meant for use in cartilage repair, in particular cartilage repair upon degradation by osteoarthritis.Type: ApplicationFiled: November 14, 2012Publication date: November 20, 2014Applicant: University of Twente, Institute for Biomedical Technology and Technical Medicine (MIRA)Inventors: Liliana Sofia Moreira Teixeira, Pieter Jelle Dijkstra, Hermanus Bernardus Johannes Karperien
