Assessment methodology of counter-personnel high power electromagnetic millimeter wave effects

The group of NLW that arguably offers the largest amount of useful applications are based on high power electromagnetic millimetre wave technology. This group is often referred to as ‘Active Denial Systems’ (ADS), since they are primarily aimed at deterring and dispersing people out of an area. The effect mechanism involves radiating millimetre...

Cooperative competition for future mobility

In May 2011, the Grand Cooperative Driving Challenge (GCDC) was held, providing the possibility for teams to develop and compare their cooperative driving solutions in a competitive setting. The challenge was organized to further accelerate developments in the area of cooperative driving. Nine international teams challenged each other to handle...

Manufacturing of high precision aspherical and freeform optics

Aspherical and freeform optical elements have a large potential in reducing optical aberrations and to reduce the number of elements in complex high performance optical systems. However, manufacturing a single piece or a small series of aspherical and freeform optics has for long been limited by the lack of flexible metrology tools. With the...

Difuse optical reflectance spectrometry in thyroid and parathyroid surgery (abstract only)

INTRODUCTION: In thyroid and parathyroid surgery iatrogenic injury of the parathyroid glands or the recurrent laryngeal nerve (RLN) is a possible complication that needs to be prevented. The visible contrast between thyroid and parathyroid tissue is delicate to observe. The aim of this pilot study was to collect in vivo spectral reflectance...

Innovaties in 3D-beeldtechniek: Driedimensionaal meekijken met de chirurg

Met de intrede van minimaal invasieve chirurgie werd 3D-zicht minder vanzelfsprekend. Daar komt steeds meer verandering in. In de console van de Da Vinci-robot beschikt de chirurg inmiddels over 3D-zicht, maar de operatieassistenten moeten het nog met tweedimensionaal beeld doen. TNO werkt samen met urologen aan beeldtechnologie waarmee de...

Results of cooperative driving applications of the SPITS project

In this paper, the design and results of two cooperative driving applications are presented that both increase traffic flow on highways by reducing shockwave traffic jams and decrease the risk of head-on collisions. The first application is an advisory system based on vehicle-vehicle communication that showed positive results with a penetration...

Chatter control in the high-speed milling process using μ-synthesis

Chatter is an instability phenomenon in machining processes which limits productivity and results in inferior workpiece quality, noise and rapid tool wear. The increasing demand for productivity in the manufacturing community motivates the development of an active control strategy to shape the chatter stability boundary of manufacturing...

Meeting highest performance requirements for lowest price and mass for the M1 segment support unit for E-ELT

The largest optical telescope in the world will be the E-ELT. Its primary mirror will be 42m in diameter. This mirror will consist of 984 hexagonal segments that are all individually supported. Each mirror will be controlled in six DOF while local shaping of the segments is provided by so called warping harnesses. These will correct for focus,...

Nieuwe perspectieven in de robotchirurgie

A270 Demo Schokgolfdemping

In februari 2010 zijn een aantal grootschalige experimenten uitgevoerd op de A270 tussen Helmond en Eindhoven. Het doel van deze experimenten is om de potentie van coöperatieve systemen te demonstreren voor het dempen van schokgolven en daarmee de mobiliteit op de Nederlandse snelwegen te kunnen vergroten. De experimenten vinden plaats op een...

Cryogenic magnetic bearing scanning mechanism design for the SPICA/SAFARI Fourier Transform Spectrometer

TNO, together with its partners Micromega and SRON, have designed a cryogenic scanning mechanism for use in the SAFARI Fourier Transform Spectrometer (FTS) on board of the SPICA mission. The optics of the FTS scanning mechanism (FTSM) consists of two back-to-back cat's-eyes. The optics are mounted on a central "back-bone" tube which houses all...
