1. A combined range finder and sighting apparatus for a weapon having a barrel having an axis, said combined range finder and sighting apparatus comprising:
- an optical range finder for calculating a distance to a selected target, said optical range finder including an optical emitter for sending an optical signal to the target and an optical detector for detecting the signal reflected from the target;
a sight assembly rotatably attached to said optical range finder;
a processor coupled to said optical range finder, said processor operably coupled to a memory storing program instructions configured to calculate a trajectory angle of the weapon based on the calculated distance to the selected target; and
a controller coupled to said processor and said sight assembly, said controller operable to control an angle of rotation of the sight assembly relative to the axis of the barrel of the weapon, such that the barrel of the weapon will be aligned with the trajectory angle when the sight assembly is aligned with the target.

17. A method of aligning a barrel of a weapon with a trajectory angle relative to a line of sight to a selected target that corresponds to a calculated distance to the selected target, said method comprising:
-
providing a combined range finder and sighting apparatus, said combined range finder and sighting apparatus including;
an optical range finder for calculating a distance to a selected target, said optical range finder including an optical emitter for sending an optical signal to the target and an optical detector for detecting the signal reflected from the target;
a sight assembly rotatably attached to said optical range finder;
a processor coupled to said optical range finder, said processor operably coupled to a memory storing program instructions configured to calculate a trajectory angle of the weapon based on the calculated distance to the selected target; and
a controller coupled to said processor and said sight assembly, said controller for operable to control an angle of rotation of the sight assembly relative to the axis of the barrel of the weapon, such that the barrel of the weapon will be aligned with the trajectory angle when the sight assembly is aligned with the target;using the optical range finder to determine a calculated distance to the selected target; using the processor to calculate the trajectory angle based on the calculated distance; and using the controller to automatically control a degree of rotation of said sight assembly so that the barrel of the weapon is aligned with the trajectory angle when the sight assembly is directed toward the selected target. - View Dependent Claims (18)
