ELECTRONIC ARCHERY SIGHTING SYSTEM AND BORE SIGHTING ARROW
First Claim
1. A sighting system for positioning a ballistic weapon such that a projectile leaving the weapon at a known speed will strike a target downrange, the system comprising:
- a bore-sight laser configured to project a laser dot downrange along an axis, such that when the bore sight laser is resting within the weapon, the laser dot indicates the attitude of the weapon;
a housing held in adjustably fixed position relation to the weapon, including;
a rangefinder to generate a target distance signal indicative of a target distance between the weapon and the target; and
a memory to store a bow speed datum, a first known reticule position based upon a first known target distance, and a second known reticule position based upon a second known target distance;
a processor to receive the target distance signal from the rangefinder; and
a display configured to depict a reticule in a reticule position relative to the target and the eye of a user, the processor generates the reticule position in response to the target distance signal, the bow speed datum, the first known reticule position, and the second known reticule position, such that the user may see the reticule overlaid on an image of the target, the reticule being positioned to indicate an attitude of the weapon necessary for the projectile to strike the target; and
a mount to hold the housing in the adjustably fixed position relation to the weapon, the adjustably fixed position being selected based upon the position of the laser dot when the bore sight laser is resting in the weapon.

Abstract
An archery sighting system and method for placing a reticule on a display. The system includes a housing mounted in fixed relation to a bow. The housing includes a rangefinder to generate a target distance signal indicative of a target distance between the bow and a target. A display is configured to depict a reticule. A chronograph generates a bow speed indicating a bow speed at which an arrow leaves the bow. A processor receives a bow speed signal from the chronograph, a range signal from the rangefinder. In response to the signals, the processor generates a reticule pattern on the display, the reticule is positioned to indicate an attitude of the bow necessary for an arrow released from the bow at the bow speed to strike a target at the target distance.

11. A method for aiming a projectile to strike a target positioned downrange, the projectile being emitted ballistically from a weapon at a bow speed, the method comprising:
-
retrieving a bow speed datum from a memory; retrieving a first known reticule position based upon a first known distance and a second known reticule position based upon a second known distance; determining a distance from the weapon to the target; extrapolating a reticule position based upon the bow speed datum and the first known reticule position, the first known distance, the second known reticule position and the second known distance; generating a reticule at the reticule position on a display such that a user can view the reticule overlaid upon a view of the target, the reticule position indicative of an attitude of the weapon suitable to have the projectile strike the target. - View Dependent Claims (12, 13, 14, 15, 16)

17. An apparatus for generating a reticule on a display at a reticule position, the reticule position being selected to indicate an attitude for the bow, the apparatus comprising:
-
the display mounted on the bow in an adjustably fixed relation; a memory including, in machine readable storage, a bow speed datum, a first reticule position for displaying a reticule on the display such when a user views the target at a first known target distance and elevates the bow such that the reticule overlays the target, the arrow released from the bow at the bow speed strikes the target, and a second reticule position for displaying the reticule on the display such that when the user views the target at a second known target distance and elevates the bow such that the reticule overlays the target, the arrow released from the bow at the bow speed strikes the target; a rangefinder for determining a target distance between the bow and the target; and a processor for extrapolating a reticule position for distances distinct from the first known target distance and the second known target distance based upon the bow speed, the first known target distance, the first reticule position, the second known distance, and the second reticule position. - View Dependent Claims (18, 19, 20)
