For the detection of the position and/or velocity of microparticles which move from dispensers of a dispensing head (30) to a target, a detector target with two linear bound, electro-acoustic or electro-optic interactive areas which fix a target plane is used. When microparticles impact on the interactive...http://www.google.fr/patents/US6467328?utm_source=gb-gplus-shareBrevet US6467328 - Process and device for detecting microparticle movement
