    The invention relates to an artificial skin (10, 12, 14), and relates to a patient simulator (100) comprising the artificial skin. The artificial skin is a layered structure comprising a translucent cover layer (20) configured for imitating human or animal skin, and comprising a light emitting layer (30, 32, 34) being configured for emitting light from a surface of the light emitting layer through the translucent cover layer for adapting the color of the artificial skin into a predefined color of the artificial skin, a lateral dimension of the light emitting layer being configured to closely imitate a real-life coloring of the artificial skin. The light emitting layer may, for example, extend substantially parallel to at least a part of the translucent cover layer for substantially following an outer topography of the artificial skin. The light emitting layer may also comprises a lateral shape (L, Lx, Ly) substantially corresponding to a shape of an area of the human or animal skin being changeable to the predefined color. The effect of the artificial skin according to the invention is that a real-life coloring effect is achieved in the artificial skin which provides excellent training quality

    Design of a Magnetic Bearing

    A popular approach to nano-positioning requirements in precision engineering in general and micro-lithography in particular is to subdivide the stage positioning architecture into a coarse positioning module with micrometer accuracy (Long Stroke), onto which a fine positioning module (Short Stroke) is cascaded. The latter is responsible for correcting the residual error of the coarse positioning module to the last nanometers. High accuracy positioning in 6 Degrees Of Freedom put severe constraints on the actuators and/or bearing systems. Actuators are used for generating a varying force being part of a control loop. Bearing systems should generate a force as constant as possible in the bearing direction, but the force perpendicular to that direction should be as low as possible. Actuators could serve as a bearing system, but on the one hand this would require the actuators to be large and thus heavy and on the other hand a substantial amount of heat is continuously dissipated in order to generate the static forces. Such heat generation does not contribute to the positioning performance of the actuators, but significantly affects the thermal stability of the application. The latter implication will be overcome if the bearing system is established by a system with permanent magnets

    The present invention relates to a patient simulator comprising an elongated flexible conduit for simulating a human or animal fluid conduit. The patient simulator to that end comprises detection means for detecting local deformation of the cross-section of the conduit. The present invention further relates to a method for simulating constriction of a human or animal fluid conduit in a patient simulato

    Dit artikel behandelt concepten die nodig zijn om een integratie van het ontwerp en de fabricage van discrete produkten te realiseren. Deze concepten zorgen ervoor dat de ontwerper al in de ontwerpfase wordt geconfronteerd met fabricagebeperkingen. De grote voordelen van deze methode zijn dat een kortere doorlooptijd van ontwerp tot en met gefabriceerd produkt kan worden gerealiseerd. dat een betere produktkwaliteit wordt bereikt. dat het ontworpen produkt inderdaad gemaakt kan worden en dat de gefabriceerde produkten direct vanaf het begin voldoen aan de ontwerpspecificaties. De beschreven concepten zijn geïmplementeerdmet behulp van deACI5 solid modeller op een PC
