LinoSPAD: a time-resolved 256x1 CMOS SPAD line sensor system featuring 64 FPGA-based TDC channels running at up to 8.5 giga-events per second

Edoardo Charbon, Claudio Bruschini, Samuel Burri

LinoSPAD is a reconfigurable camera sensor with a 256x 1 CMOS SPAD (single-photon avalanche diode) pixel array connected to a low cost Xilinx Spartan 6 FPGA. The LinoSPAD sensor's line of pixels has a pitch of 24 pm and 40% fill factor. The FPGA implements ...

Dual Langmuir-probe array for 3D plasma studies in TORPEX

Ambrogio Fasoli, Ivo Furno, Marcelo Baquero Ruiz, Rémy Jacquier, Fabio Avino, Oulfa Chellaï, Fabian Manke

We have designed and installed a new Langmuir-probe (LP) array diagnostic to determine basic three-dimensional (3D) features of plasmas in TORPEX. The diagnostic consists of two identical LP arrays, placed on opposite sides of the apparatus, which provide ...

Reaching millikelvin resolution in Raman distributed temperature sensing using image processing

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

Image processing is proposed and experimentally demonstrated to improve the capabilities of Raman distributed optical fibre sensors. The here reported technique consists in stacking consecutive one-dimensional Raman Stokes and anti-Stokes traces in two-dim ...

Broadband electronically tunable reflection-based phase shifter for active-steering microwave reflectarray systems in Ku-band

This document provides the design of an electronically reconfigurable microwave phase shifter for reflectarray systems. The phase shifter is based on a hybrid coupler with reflective circuits in three ports. Each reflective circuit introduces a phase varia ...

Using pot-magnets to enable stable and scalable electromagnetic tactile displays

Herbert Shea, Juan José Zarate

We present the design, fabrication, characterization and psychophysical testing of a scalable haptic display based on electromagnetic (EM) actuators. The display consists of a 4x4 array of taxels, each of which can be in a raised or a lowered position, thu ...

High-resolution, large-area fabrication of compliant electrodes via laser ablation for robust, stretchable dielectric elastomer actuators and sensors

Herbert Shea, Samuel Rosset, Oluwaseun Adelowo Araromi

A key element in stretchable actuators, sensors and systems based on elastomer materials are compliant electrodes. While there exist many methodologies for fabricating electrodes on dielectric elastomers, very few succeed in achieve high-resolution pattern ...

Flutter Suppression of a Bridge Section Model Endowed with Actively Controlled Flap Arrays

Alcherio Martinoli, Klara Maria Boberg

In this work, we investigate active flutter control of a bridge section model equipped with arrays of flaps. We consider three simple control algorithms based on an amplitudegain and a phase-shift for actuating the flaps and stabilizing the section model. ...

Enhancing Design Space Exploration by Extending CPU/GPU Specifications onto FPGAs

Paolo Ienne, Andreas Peter Burg, David Novo Bruna, Georgios Karakonstantis, Gabriel Falcao Paiva Fernandes, Madhura Purnaprajna

The design cycle for complex special-purpose computing systems is extremely costly and time-consuming. It involves a multiparametric design space exploration for optimization, followed by design verification. Designers of special purpose VLSI implementatio ...

Room temperature concurrent formation of ultra-dense arrays of ferroelectric domain walls

Alexander Tagantsev, Nava Setter, Ludwig Feigl, Petr Yudin, Konstantin Shapovalov, Mahamudu Mtebwa

Properties of ferroelectric domain walls are attractive for future nano- and optoelectronics. An important element is the potential to electrically erase/rewrite domain walls inside working devices. Dense domain wall patterns, formed upon cooling through t ...

LDPC Codes for 2D Arrays

Mohammad Amin Shokrollahi

Binary codes over 2D arrays are very useful in data storage, where each array column represents a storage device or unit that may suffer failure. In this paper, we propose a new framework for probabilistic construction of codes on 2D arrays. Instead of a p ...
