    Abstract: In an automated analyzer that measures concentration of samples by comparing changes in a detector response caused by said samples to a calibration curve or factor based on one or more different calibration standards stored in the analyzer, a replacement calibration standard is validated automatically by processing a portion of said replacement calibration standard as a sample prior to accepting the new calibration standard as a valid standard.

    Abstract: A reflectometric method of measurement for a 2-channel reflectometer, wherein in connection with the calibration, the standard sample is placed in the measruing channel (4), the dimming of the measuring channel is set to a random position and the light intensities detected both in the measuring channel and the reference channel (14) are adjusted into balance by adjusting the dimming of the reference channel by aid of the measuring diaphragm (17), and the measuring of the sample is carried out by setting the intensities into balance, likewise by aid of the measuring diaphragm of the reference channel. The reflectance value of the sample under measurement is calculated from the reflectance value of the standard, by aid of the set value of the measuring diaphragm obtained in the measurement and on the basis of the set value of the measuring diaphragm obtained in the calibration measurement.

    Abstract: An automatic analyzing apparatus and method transfers a sample to be examined to a sampling position, fractionally injects the sample into a reaction vessel by using sampling means, adds a reagent to the reaction vessel holding therein the sample fractionally injected to cause reaction, and measures absorbance of the reaction solution at predetermined time intervals using a photometer. A first check for checking whether an abnormality is present in the measurement result of each measurement item is made, followed by a second check for checking whether an abnormality is present on the basis of a change in the rate of absorbance measured after the reagent is added to the sample in the reaction vessel. Then, a third check computes correlation of measured absorbance data and checks whether an abnormality is present on the basis of the result of computation. Finally, a determination is made, with respect to the sample in accordance with an abnormal item when it is judged that an abnormality is present in the result of the first, second or third check, whether remeasurement is necessary, and for selecting, in case of remeasurement, either remeasurement under the same conditions or remeasurement with a reduced sample quantity as compared with that of the first measurement conditions. When remeasurement is determined, the sample is carried to the sampling position.

    Abstract: An image processing method and apparatus determines a proliferation index of a cell sample by staining the cells with a chromogen for a proliferation substance and a counterstain for the cell nuclei. The chromogen is activated by an antibody-enzyme conjugate which binds to the proliferation substance to produce a stained cell sample. The stained cell sample is examined with an optical microscope, forming a portion of the apparatus, which produces a magnified cell sample image. The apparatus optically filters the cell sample image and produces a pair of optically enhanced proliferation substance and cell nuclei images. The enhanced images are electronically analyzed to determine the amounts of cell nuclei and proliferation substance appearing in the images, respectively. The amounts are then compared to yield a proliferation index for the portion of the cell sample appearing in the cell sample image.

    Abstract: Sensing apparatus for remote sensing of quantities such as blood oxygen concentration using a phosphorescent material located at one end of an optical fiber. The phosphorescent material emits a relatively long-lived luminescence when exposed to energy in a predetermined wavelength range. The sensing apparatus includes a light source for generating an incident pulsed energy signal within the predetermined wavelength range and a detector subsystem for selectively detecting the long-lived luminescence from the phosphorescent material. The light source and the detector subsystem are coupled to the other end of the optical fiber along a common optical path. The detector subsystem includes dual channels for detecting a measuring wavelength and a reference wavelength in the long-lived luminescence. The detector subsystem is inhibited during the incident pulsed energy signal to provide low noise operation. The detected signals are integrated and averaged to improve accuracy. A calibration source is provided for calibrating the detection subsystem.

    Abstract: An image apparatus for measuring true mass characteristics of the specimen in real time is provided with means for controlling the amount and intensity of background light so that the amount of light is held substantially constant and at a level providing reduced background and scattered light so that evaluations at different times on the same or on different image analysis apparatus of the same manufacture result in substantially identical measurements of mass. The light control for the conventional light microscope used with the image analysis apparatus includes four variables which are the light intensity of the light bulb, the size of the field iris, the size of the condenser iris, and the movement the condenser lenses in a vertical or "Z" direction for focus. Preferably, a fixed aperture means in the form of a cup attachment is secured to the condenser iris optics to provide a fixed size iris for the condenser. The controls for the variable condenser iris are opened wide so that the less size aperature in the fixed condenser iris is that which is controlling of the light passing through the condenser optics. The preferred attachment device is a cup-shaped member of one piece metal which is attached by a threaded fastener in a non-invasive manner to the bottom of the condenser iris and optics. A monitor displays the intensity of the background light as a numerical value and the intensity of the light bulb is adjusted to provide a substantially constant background light transmitted to a CCD sensor or camera.

    Abstract: A transmissometer includes electronic shutters for interrupting the transmitted and reference light beams at selected locations and at selected time intervals for establishing the various modes of operation of the transmissometer. The electronic shutters take the form of liquid crystal displays that are selectively energizable to either a clear or an opaque condition. The transmissometer also includes an electronic stepwise light attenuator located in the path of the light beams. The attenuator includes a body and multiple liquid crystal display segments uniformly distributed throughout the body, with the segments being independently energizable to provide stepwise opacity.
