TODAY’S PATENT -LUMINOUS DOT SIGHTING INSTRUMENT
In today’s patent, we will discuss Alfred C. DePaoli (Woburn, MA)’s invention, “Luminous Dot Sighting Instrument” (US5205044A), which was patented by the USPTO on April 26, 1993.
This following invention relates to such instruments which are used in connection with a telescope as an aid to sighting the firearm on a target. Here the dot is generally created inside the instrument and it does not need light from the view rather it can be as bright as per the requirements of the user. Under the following invention dots of different colors are created with the help of different mirror coatings that reflect different wavelengths of light from a single diode or several diodes of the same color, or from different color. In some occasions the two separate images of the source imposed on the target view image are of different colors or different brightnesses of the same color. The separate images can thereby used by the marksman to sight on the target at different ranges and the position or the brightness or the color of the luminous dot can be representative of range to the target. The luminous dot sighting instrument with variable dots enables the marksman to have additional options for sighting more quickly and accurately on a target.
