An Orthogonal Fluxgate-Type Magnetic Microsensor

Radivoje Popovic, Pavel Kejik, Franck Vincent, Ozge Zorlu

In this paper, we present a new microfabricated orthogonal fluxgate sensor structure. The sensor consists of an electroplated copper excitation rod surrounded by an electroplated permalloy layer and has planar pick-up coils for signal detection. The use of ...

Portable optical microscope-on-a-chip

Demetri Psaltis

In this paper, we present a novel high resolution optical imaging device on chip. It is based on a line of nano holes defined in an optically opaque aluminum film on a CMOS imaging sensor chip. Because it's free of bulky optical elements and compatible to ...

CMOS pixels for subretinal implantable prothesis

Mihai Adrian Ionescu, Philippe Renaud, Marco Mazza

This work reports on the design, fabrication, and characterization of CMOS pixels for subretinal implants, which seems to be an effective way to recover visual capabilities in some types of blindness. Two possible approaches are presented for CMOS pixel im ...

Nanostencil technique and its applications to Nanoelectronics

Jürgen Brugger, Oscar Vazquez Mena

The Nanostencil technique is an emerging nanopatterning method based on shadow mask evaporation. Micro and sub-micron apertures (down to 100-nm scale) are patterned in 100-500 nm thick low-stress silicon nitride membranes. The membrane is brought in close ...

Application of CMOS image sensors in optical sectioning and polarization microscopy

Jelena Mitic

In this thesis new imaging approaches for optical microscopy are proposed and studied. They are based on the use of dynamic structured illumination in combination with a demodulation detection concept employing CMOS image detectors. Two particular implemen ...

Integrated fluxgate compass for portable applications

Predrag Drljaca

Modern applications in industry, navigation and medicine demand small and sensitive magnetic field sensors. In this thesis we have developed a new planar micro fluxgate magnetometer. High resolution, low power consumption and orthogonal fields detection ma ...

New support vector algorithms for multicategorical data applied to real-time object recognition

Silvio Borer

Humans have the ability to learn. Having seen an object we can recognise it later. We can do this because our nervous system uses an efficient and robust visual processing and capabilities to learn from sensory input. On the other hand, designing algorithm ...

CMOS image sensors for subretinal implant system

Mihai Adrian Ionescu, Philippe Renaud, Marco Mazza

Visual capabilities recovery for some kind of illness is possible through subretinal implantable device stimulation. Two possible approaches for retinal pixel are proposed, fabricated in 0.35mum CMOS, tested and compared including electronic response on a ...

Efficient ASIC implementation of a real-time depth mapping stereo vision system

Andreas Peter Burg, Simon Karl Moser

This paper presents a fast and area-efficient implementation of a real-time stereo vision algorithm for spatial depth mapping. The design combines two well-known area-based approaches to stereo thatching and includes an occlusion detection method. Hardware ...
