An electronic device which guides the perforating equipment during stamp manufacture. This is accomplished by heavy ink dashes in the selvage, which are used for detection and alignment. FDCs of EE stamps must have the selvage with dashes attached to the stamps.
In 1933, starting with the two-cent stamp, Scott 634, the Bureau of Engraving and Printing began experiments to improve the perforation process. The plate block at right is from one of the first electric eye plates ever printed. Note the position of the plate number, it's not in the corner as rotary press plate numbers normally are. The electric eye makes use of a photovoltaic cell employing a beam of light to aid in perforation accuracy. Although the experimental sheets had a series of dashes down the very center of the sheet and a single dash in the center of the left margin, the electric eye markings we are familiar with were not added to the sheet margins until 1939. The philatelist may note that many stamps after 1940 always seem to be well-centered. The electric-eye had a large part in this.
1.) a device which employs a beam of light to facilitate more accurate perforation of stamps during the manufacturing process. 2.) the markings (see Electric Eye Dashes, Electric Eye Margin Line, Electric Eye Gutter Bar, and Electric Eye Frame Bars) in the margins and gutters of sheets of stamps that enable the electric eye device to accomplish its purpose of more of accurately perforating stamps. Stamps with electric eye markings were first sold in 1935.
A device that creates a light beam, the interruption of which will activate a relay switch for control of a desired animation.
Electric Eye is a compilation DVD by Judas Priest released in 2003.
Electric eye is a somewhat dated term used to describe a simple electrical means of sensing something. An example is the door safety system used on garage door openers that use a light transmitter and receiver at the bottom of the door to prevent closing if there is any obstruction in the way that breaks the light beam.
Electric Eye is a song from Judas Priest's 1982 album Screaming for Vengeance.
