摘要:
An automatic high-speed pill counting apparatus comprising: a cylindrical pill hopper (3) having a pill exit (10) and a center hole in a base plate (2); a rotational separative feeder (5) mounted in the cylindrical pill hopper and removably fitted on a shaft (6) borne in the center hole of the base plate, the feeder including an upper diametrically smaller portion (5b) and a lower diametrically larger portion (5c) having an external diameter approximate to the internal diameter of the lower portion of the pill hopper, a multiplicity of vertically through holes (5c) being formed in the outer circumference of the lower diametrically larger portion and allowed to come into alignment with the pill exit for accommodating a plurality of pills vertically, the multiple vertically through holes (5d) being enlarged at their lower portions, a ring-shaped slit (8) being formed in such a position in the outer circumference of the lower diametrically larger portion as to accommodate substantially one pill from the bottom; and a pill separating plate (11) mounted on the cylindrical pill hopper (3) above the pill exit and having an inwardly projected tip fitted loosely in the slit (8).

The present invention relates to a method and apparatus for counting the number of microorganism colonies present on a disposable microorganism culturing device having a substantially planar substrate. The preferred apparatus (10) of the present invention includes an LED bar (20) illuminating the surface of the substrate and a linear array of SELFOC lenses (22) which focus the light reflected off of the substrate onto a linear CCD sensor array (24). The CCD sensor array (24) is connected to a microprocessor (32) which analyzes the raster-scanned data using the preferred algorithm. The preferred algorithm used the sigma-shaped neighborhood for image processing. The preferred algorithm passes the sigma region across the image in a raster-scanned order to detect object starts and merges which yield a colony count for a scanned microorganism culturing device.

Bei einem nach dem Abdunklungsverfahren arbeitenden Partikelzähler mit einer Lichtschranke, deren Lichtstrahl einen Meßkanal für ein Fluid quer zur Kanallängsrichtung durchdringt, und einer dem Empfänger der Lichtschranke nachgeschalteten Auswerteelektronik ist die Lichtaustrittsfläche der Lichtschranke durch die Endfläche einer Beleuchtungsfaser (17) und die Lichteintrittsfläche durch die Endfläche einer Empfängerfaser (19) gebildet. Die Endfläche der Beleuchtungsfaser (17) liegt in einer ersten Begrenzungsfläche des Meßkanals (12) und die konzentrisch zu dieser Endfläche angeordnete Endfläche der Empfängerfaser (19) in einer zur ersten Begrenzungsfläche parallelen zweiten Begrenzungsfläche des Meßkanales (12).
摘要:
A method of counting, in real time, articles supplied on a conveyor track in a random pattern is disclosed. The method comprises forming an image of the articles present in a counting zone by means of an image pick-up device, which counting zone corresponds to a periodic, elongated image of the image pick-up device, which image extends essentially transversely to the direction of movement of the conveyor track. The elongated image is converted into a binary image composed of a row of image elements, each with its own grey value, which binary image is obtained by assigning a first logic state to image elements having a grey value above a pre-determined threshold value and a second logic state to image elements below this threshold value. The invention is characterized by determining whether an article arrived in the counting zone, whether the article subsequently reaches a minimum width in the image, and whether the article leaves the counting zone again, whereby a count signal is produced when the article leaves the counting zone.

A computer-implemented method for use in determining the distribution of objects in a tubular structure is provided. The method comprises: receiving a representation of a cross-sectional slice of the tubular structure; based on the representation, determining a number of the objects in each of a plurality of circular sectors of the cross-sectional slice; and based on the number of objects in each of the plurality of circular sectors, outputting an indication of the distribution of the objects.
