Abstract
Abstract A visual display unit adapted to graphically create the illusion of flow through a biological image such as the heart or nervous system. The illusion of flow is created by means of one or more rows of lamps which are adapted to be lighted in sequence along the rows. The rows are mounted behind a translucent panel on which the image is carried, and are positioned in a predetermined relationship with respect to the image so as to accurately reflect the flow pattern through the image. Thus when the flashing lamps are viewed through the image, the flow pattern will be apparent to the observer. Where more than one row of lamps is employed, means may be provided for independently actuating each row whereby different flow patterns may be illustrated.

Claim 1
Independent Claim
327 words
An educational display apparatus for graphically illustrating the flow of blood through the heart during a cycle of operation thereof and comprising, a translucent panel, means on said panel for defining a translucent image of the heart a plurality of lamps, a second panel disposed closely adjacent and parallel to said translucent panel, means mounting said lamps on said second panel in at least three rows with a first row disposed in predetermined fixed alignment behind said image defining means and in correlation with the pattern of blood flow during the resting interval of the heart cycle, a second row disposed in predetermined fixed alignment behind said image defining means and in correlation with the pattern of blood flow during ventricular contraction of the heart, and a third row disposed in predetermined fixed alignment behind said image defining means and in correlation with the pattern of blood flow during ventricular recovery of the heart, means for sequentially illuminating the lamps along each of said rows to create the illusion of movement along said rows and flow through the heart when the heart image on the translucent panel is viewed from the side opposite said second panel, means for independently actuating said illuminating means of said rows in an automatic sequence whereby the blood flow during the three portions of the heart cycle may be independently and sequentially illustrated, a second translucent panel, means on said second panel for defining a translucent image of an EKG trace, first lighting means operatively connected with said illuminating means for illuminating the resting segment of the EKG trace when said first row of lamps is lighted, second lighting means operatively connected with said illuminating means for illuminating the ventricular contraction segment of the EKG trace when said second row of lamps is lighted, and third lighting means operatively connected with said illuminating means for illuminating the ventricular recovery segment of the EKG trace when said third row of lamps is lighted.

An educational display apparatus for graphically illustrating the flow of blood through the heart during a cycle of operation thereof and comprising, a translucent panel, means on said panel for defining a translucent image of the heart a plurality of lamps, a second panel disposed closely adjacent and parallel to said translucent panel, means mounting said lamps on said second panel in at least three rows with a first row disposed in predetermined fixed alignment behind said image defining means and in correlation with the pattern of blood flow during the resting interval of the heart cycle, a second row disposed in predetermined fixed alignment behind said image defining means and in correlation with the pattern of blood flow during ventricular contraction of the heart, and a third row disposed in predetermined fixed alignment behind said image defining means and in correlation with the pattern of blood flow during ventricular recovery of the heart, means for sequentially illuminating the lamps along each of said rows to create the illusion of movement along said rows and flow through the heart when the heart image on the translucent panel is viewed from the side opposite said second panel, means for independently actuating said illuminating means of said rows in an automatic sequence whereby the blood flow during the three portions of the heart cycle may be independently and sequentially illustrated, a second translucent panel, means on said second panel for defining a translucent image of an EKG trace, first lighting means operatively connected with said illuminating means for illuminating the resting segment of the EKG trace when said first row of lamps is lighted, second lighting means operatively connected with said illuminating means for illuminating the ventricular contraction segment of the EKG trace when said second row of lamps is lighted, and third lighting means operatively connected with said illuminating means for illuminating the ventricular recovery segment of the EKG trace when said third row of lamps is lighted.
Claim 3
Dependent Claim
79 words
The educational display apparatus as defined in claim 1, wherein the means for sequentially illuminating the lamps along each of said rows is adjustable to vary the rate of sequential illumination of the lamps such that the speed of the illusion of movement along the rows may be varied, and said means for independently actuating the illuminating means of said rows in an automatic sequence is adjustable such that the speed of the illustrated heart cycle may be varied.
