    Abstract: An invention is described which allows measurement of the concentration of fluorescent particles in a flowing (laminar) fluid by imaging the flow with a video camera. A beam of illumination is used to illuminate the target particles. Imaging optics are arranged to view the focal plane to form an image of the multiple fluorescent sample particles in the flow stream; a camera records the image formed by the imaging optics, and a counting algorithm enumerates the particles. Operational parameters of the system are adjusted according to an initial estimate of particle density, for example flow rate, exposure time, and sampling interval. In addition, the counting algorithm is selected according to the estimated particle density.

    Abstract: A method and apparatus for determining the number of particles or cells in a liquid sample. The method comprises a) determining the number of particles or cells in a first volume of the liquid sample, b) determining the statistical uncertainty of the determined number of particles in said first volume, c) if the determined uncertainty is larger than a pre-determined value, determining the number of particles or cells in a further volume of the liquid sample, d) adding the numbers of cells or particles determined in steps a) and c), e) determining the statistical uncertainty of the number of particles determined in step d), f) repeating steps d) and e) with a further volumes of the liquid sample, until the uncertainty determined in step e) is lower than said pre-determined value or until a pre-determined total volume of the liquid sample in which the number of cells or particles has been determined exceeds a pre-determined volume being larger than said first volume. In this way, the volume examined and the uncertainty of the measurement may be selected so that a suitable compromise between the uncertainty and the time required to perform the measurement can be obtained. The apparatus according to the invention comprises a liquid flow system allowing the measurement sequence to be interrupted as soon as the calculating means decide that the uncertainty of the actual cell count is small enough to rely on the present determination. The apparatus will then be ready to carry on with the next sample, thereby maintaining a high capacity while obtaining reliable cell counts.

    Abstract: To evaluate cleanliness of wafer accommodating members used for storing or transporting of silicon, gallium arsenide or like semiconductor wafers, pure water is poured into a vessel-like wafer accommodating member, such as a wafer case body, a top cover, etc., capable of containing liquid therein, and then low frequency vibrations or supersonic wave is applied to the member. Alternatively, inner wafer accommodating members accommodated in the wafer case body, such as a wafer basket, a wafer retainer, etc., are accommodated in a vessel containing poured pure water, and the low frequency vibrations or supersonic wave is applied to the members. Then, the quantity of particles in the water is counted. Particles that have been attached to the wafer case or to inner wafer accommodating members accommodated therein, such as a wafer basket, a wafer retainer, etc., are made readily separable into the water, thus permitting quantitative detection of generation of particles from the inner wafer accommodating members.

    Abstract: Apparatus for determining parameters of any number of selected regularly or randomly oriented particles, or images or image patterns thereof, of various size and shape lying within a discrete region. A scanning device is swept over the discrete region causing the generation of electrical signals in response to the interception of the boundaries of one or more of the particles. Apparatus, including, for example, a light pen, for use in cooperation with a display of the feature images is operated to best identify, select or prepare for analysis features of interest within the discrete region. In cooperation with such apparatus appropriate logic and electronic circuitry which is adapted to receive the initially generated signals provide, in response thereto, other signals related to the feature or features of interest and any particular parameter related to those features.

    Abstract: An automatic cell counter which includes a video camera for viewing a sample being scanned. The video output is quantized by means of a level detector which compensates for variations and non-uniformities of the background field and produces a signal identifying a cell as having a certain absorption relative to a preselected absorption level. The quantized signal from the level detector passes through a discriminator which produces an output flag for each cell having a predetermined size level. Thus, cells can be selected having a combination of predetermined size and absorption levels. By utilizing line to line comparison, a single flag is provided for each cell desired to be counted. The flags are counted and the entire video output is displayed with the flag superimposed upon each cell counted.

    Abstract: A method and apparatus is described for determining the susceptibility of a significant microorganism in a biological sample to different anti-microbial agents, and for providing its antibiotic susceptibility profile. Quotients of the biological sample are provided to a plurality of biological chambers, two of such chambers being used as internal ''''start'''' and ''''reference'''' controls. In the remaining biological chambers, proliferation of the significant microorganism is challenged by the addition of selected antibiotics. In the ''''start'''' control chamber the microorganisms are ''''killed'''' simultaneously with the addition of antibiotics to the biological chambers; after incubation, the microorganisms in the remaining biological chambers and, also, the ''''reference'''' control chambers are ''''killed'''' concurrently. Each of the biological chambers and the control chambers are sampled, and the total particulates, i.e., nonviable and ''''killed'''' microorganisms and, also, any dust or dirt particles, are counted in particular sequence, and the respective counts are logically related, so as to signify the susceptibility of the significant microorganism to each of the antibiotics. The results are graphically recorded, so as to provide an antibiotic susceptibility profile of the significant organisms.

    Abstract: Light from a localized source is projected through a transparent bacterial culture medium having a multitude of bacterial colonies formed on the surface thereof. The bacterial colonies serve as lenses for focusing images of the light source into a pattern of images which are projected into an image plane forming a pattern of light images corresponding to the pattern of bacterial colonies. A linear array of photodetectors is disposed in the projected image plane. The optical system is scanned relative to the bacterial colony culture such that adjacent scanning tracks overlap each other by approximately the track width of two photodetectors of the array of photodetectors. An output pulse, which is to be counted, from one detector inhibits counting output pulses from its nearest neighbors and the output pulses from the detectors at opposite ends of the array are not counted to form guard detectors, whereby colonies are accurately counted and colonies which overlap adjacent scanning tracks are counted but only once.
