  • Patent number: 4274149
    Abstract: An apparatus for providing superimposed readout of digital information onto the field of view in binoculars, with said digital information typically being related to elapsed time. A chronometer device of the type commonly employed in electronic watches having an LED display is mounted internally of a conventional housing for binoculars (or a similar optical instrument). The chronometer device measures elapsed time in a conventional manner; and, the switches for controlling the chronometer device are preferably mounted on the right barrel of the binoculars, where they may be activated by either the thumb or index finger of a person's right hand. An LED digital display is mounted internally of one of the barrels, preferably the right barrel, where the display may be seen when a viewer looks through the binoculars. The digital display is biased so as to always remain immediately next to the eyepiece of one barrel, in order that it will remain in focus when any focusing adjustment is made by the viewer.
