Apparatus and method for displaying and storing impact points of firearm projectiles on a sight field of view
First Claim
1. Apparatus for sighting a target for an actual or simulated firearm by means of simulating the impact point of a projectile discharged from the same, said apparatus comprising:
- a) trajectory calculating unit on or adjacent to said firearm programmed to calculate the effect of trajectory modifying conditions on a location of at least one projectile impact point in relationship to the zero-range reticle calibration;
b) a display unit for displaying images;
c) means for providing a zero-range reticle on a display unit image;
d) an optical image conversion unit on said firearm for converting an optical image viewed by said optical image conversion unit to electronic signals, said optical image conversion unit sending said electrical signals to an appropriately interfaced display unit on or adjacent to said firearm, said display unit responsive to said electronic signals for displaying a field of view image;
e) image means coupled to the display unit and responsive to said trajectory calculating unit for superimposing at least one impact point reticle on said field of view; and
storage means for storing said electronic signals including electronic signals representing said reticle in response to activation of a firearm trigger, wherein said trajectory calculating unit determines a time of flight of said projectile after said firearm trigger activation, said storage means storing second field of view from said optical image conversion unit after a time equal to said time of flight.

Abstract
Apparatus and method for determining and recording a calculated impact point of one or more projectiles discharged from a firearm include a sighting mechanism with a field of view display unit, sensor elements, a recording unit, and a trajectory calculating microprocessor unit, the microprocessor unit for storing parameter data and for responding to sensor and/or manual data input signals and modifying the image presented by the field of view display unit. The trajectory calculating microprocessor unit, in response to the sensor data and parameter data, determines the trajectory of a projectile. The calculated impact point of the projectile is used to superimpose an indicia, namely an impact point-reticle on the image of the field of view of the display unit relative to the zero-range reticle or standard cross-hair setting.

13. The method for sighting a firearm, the method comprising the steps of:
-
converting an optical image of a firearm sighting field of view into electrical image signal when a firearm trigger is activated; processing parameter data signals to determine trajectory electrical signals for a projectile fired from said firearm, said trajectory electrical signals determining a projectile impact point; combining said image electrical signals and said trajectory electrical signals to provide combined electrical image signals; storing said combined electrical image signals; converting an optical image of said firearm sighting field into second electrical image signals at a time of projectile impact; storing said second electrical image signals; and displaying a combined image provided by displaying said combined electrical image signals simultaneously with said second electrical image signals, a comparison of said combined image determining a firearm sighting accuracy. - View Dependent Claims (14, 15, 16, 17, 18, 19)
