ABSTRACT:
An assembly for identifying the results of a specimen analysis wherein such specimen analysis occurs in an array of discrete cells. The assembly includes a housing having top, bottom, end walls, and sidewalls. An array receiving recess is provided on the top wall for receiving and holding in a fixed position the array of the discrete cells. An ultrasonic signal producing stylus is provided for selectively producing an ultrasonic signal adjacent a cell in the array in which the results of the analysis are to be identified. A first ultrasonic signal transducer is provided on the top wall for converting the ultrasonic signal from the ultrasonic signal generator to a first electrical signal. A second ultrasonic signal transducer is provided on the top wall for converting the ultrasonic signal from the ultrasonic signal generator to a second electrical signal. A microprocessor is provided electrically operatively connected to the first ultrasonic signal transducer, the second ultrasonic signal transducer, and the ultrasonic signal producing stylet. The microprocessor compares the first and second electrical signals received and identifies such signals to the cell above which the ultrasonic signal was produced.
