    摘要: A computer priority interrupt system minimizes the computer time required to service the request of peripheral equipment. The interrupt system is priority structured with an interrupt identifier circuit which identifies the peripheral requesting service without requiring polling of all peripheral units. Priority interlocked gates, one associated with each peripheral unit, are connected in series in the order of priority. Request signals from lower priority peripheral units are passed through the interlock gate when the gates are enabled. Bistable circuitry associated with each peripheral unit blocks transmission of request signals from equal or lower priority units when the bistable circuitry is set. An encoder generates a code identifying the peripheral unit being serviced. This obviates the requirement for polling to determine which unit is being serviced.

    摘要: In an automated blood cell identification system a high resolution microscope and a split path optical system produce a blue filtered image and a yellow filtered image of an eosinophil blood cell. These images are converted into digital histograms representing the optical density of points in each image. The histograms are compared one to the other. An eosinophil cell is identified if the optical density of the histogram of the blue image is greater than the optical density of the yellow image.
