    摘要: In a method to determine or regulate flows or flow rates of liquids such as those used in medical infusion systems, optical imaging means are used for real flow measuring. The increase in volume of drops hanging at an outlet and the increase of volume of liquid gathered in a container can be measured by image acquisition and image processing. This increase of volume represents a real time flow. As an example, signals obtained from these measurements can be used to control or adjust volume flow for medical treatment or medical diagnosis. An apparatus to carry out such a method can be composed of devices well known per se.

    摘要: For forming an array or series of elementary beams of charged particles, a beam exposure device includes a mirror system having a matrix of sub-mirrors. Using such a composite mirror, a multiple beam image is formed in a location which deviates from the position of the cross-over of principal rays of the elementary beams. Consequently, the elementary beams, which may alternatively be ion beams, can be separated modulated and controlled. For suitable imaging, such as the writing of patterns for a micro-electronic circuit element, the images and the cross-over of the principal rays of the elementary beams are combined. For this purpose, use is made of a second mirror whose sub-mirrors have an optical effect which opposes that of the first mirror.
