Abstract
A ranging system for use with a projectile launching device is provided. The ranging system includes an alignment marker visible with an optical sight device. The position of the alignment marker is adjusted based at least on a determined range to a target.
Claims42
A method of indicating the expected location of a projectile relative to a target object with an optical sight, the method comprising the steps of:
- supporting an optical sight on a projectile launcher, the optical sight including a window;
- coupling an identification device of the window to a controller;
- identifying a parameter of the window from the identification device;
- determining a range to the target object;
- providing an alignment marker within the window of the optical sight;
- calibrating a position of the alignment marker based on a profile including the parameter of the window;
- and
- altering the position of the alignment marker within the window of the optical sight based at least on the range to the target object.
A ranging system for use with a projectile launching device to aim at a target object, the ranging system comprising:
- a rangefinder supported by the projectile launching device and configured to determine a range to the target object;
- an optical sight supported by the projectile launching device and including an identification device for providing a parameter of the optical sight, the optical sight further including a field of view, the target object being viewable through the field of view;
- at least one optical source which provides an alignment marker within the field of view of the optical sight, the alignment marker indicating a position that a projectile of the projectile launching device will hit at the location of the target object;
- a controller operably coupled to the rangefinder and the at least one optical source and
- an interface supported by the projectile launching device and configured to couple the identification device of the optical sight with the controller, wherein the controller determines a position of the alignment marker within the field of view of the optical sight based at least on the range to the target object and the parameter from the identification device.
A ranging system for use with a projectile launching device to aim at a target object, the ranging system comprising:
- a rangefinder supported by the projectile launching device and configured to determine a range to the target object;
- an optical sight supported by the projectile launching device;
- the optical sight including a mount, a window supported by the mount, and a coupler removably coupling the window to the mount, the window including an identification device for providing a parameter of the window, the optical sight permitting the viewing of the target object through the window;
- an optical source providing an alignment marker within the window of the optical sight, the alignment marker indicating a position that a projectile of the projectile launching device will hit at the location of the target object;
- an interface supported by the mount and operably coupled to the identification device of the window;
- and
- a controller operably coupled to the rangefinder, the interface, and the optical source, the controller determining a position of the alignment marker within the window of the optical sight based at least on the range to the target object and the parameter of the optical window.
