High-speed CMOS magnetic angle sensor based on miniaturized circular vertical Hall devices

Radivoje Popovic, Mirjana Banjevic

We present a high-speed CMOS integrated magnetic angle sensor consisting of two 8-contact circular vertical Hall devices (CVHD). The biasing and sensing of the Hall voltage is rotated clockwise for the first device, and counter clockwise for the second one ...

A Multi-Site Campaign To Measure Solar-Like Oscillations In Procyon. Ii. Mode Frequencies

We have analyzed data from a multi-site campaign to observe oscillations in the F5 star Procyon. The data consist of high-precision velocities that we obtained over more than three weeks with 11 telescopes. A new method for adjusting the data weights allow ...

Ray tracing study for non-imaging daylight collectors

Jean-Louis Scartezzini, Jérôme Henri Kämpf, Friedrich Linhart

This paper presents a novel method to study how well non-imaging daylight collectors pipe diffuse daylight into long horizontal funnels for illuminating deep buildings. Forward ray tracing is used to derive luminous intensity distributions curves (LIDC) of ...

Integrating sphere for the optical analysis of luminescent materials

Frédéric Gumy

An integrating sphere for measuring quantum yield comprises a sample holder, for example a capillary (7) adapted to be placed in a quartz tube (12) comprised in the sphere, an inlet opening for introducing an excitation beam (10), and an outlet opening for ...

Non-Gaussianity analysis on local morphological measures of WMAP data

Pierre Vandergheynst, Yves Wiaux

The decomposition of a signal on the sphere with the steerable wavelet constructed from the second Gaussian derivative gives access to the orientation, signed-intensity and elongation of the signal’s local features. In the present work, the non-Gaussianity ...

Circular Hall transducer for angular position sensing

Radivoje Popovic, Pavel Kejik

We developed a new integrated magnetic sensor based on the Hall effect, suitable for the application in magnetic contactless 360° absolute angle sensors. The device consists of a narrow n-well ring with a chain of 64 contacts equally distributed around the ...

About the influence of friction and polydispersity on the jamming behavior of bead assemblies

Thomas Liebling, Lionel Pournin, Marco Ramaioli

We study the jamming of bead assemblies placed in a cylindrical container whose bottom is pierced with a circular hole. Their jamming behavior is quantified here by the mean critical diameter, that is the diameter of the hole for which the jamming probabil ...
