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 disposed in the projectile configured to project a laser dot downrange along an axis of the projectile, such that when the projectile 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 and a known reticule position based upon a known target distance;
a processor to receive the target distance signal from the rangefinder; and
a display configured to depict the reticule and an electronic aiming indicator, the electronic aiming indicator replacing the reticule on the display and being located in a shifted position corresponding to the target distance signal and the eye of a user, the processor configured to generate the shifted position in response to the target distance signal, the bow speed datum and the known reticule position, such that the user sees the electronic aiming indicator overlaid on an image of the target in the shifted position indicating 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 projectile 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 hunting 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; displaying a reticule on a display operatively coupled to the weapon; storing in memory a reticule position based upon a known target distance; projecting from a bore-sight laser disposed in the hunting projectile a laser dot downrange along an axis of the projectile; determining a measured distance from the weapon to the target based upon the laser dot; extrapolating an aiming indicator position based upon the bow speed datum and the attitude of the weapon, the stored reticule positionand the known target distance; replacing the reticule on the display with an electronic aiming indicator positioned at the extrapolated aiming indicator reticule position on a display such that a user can view the electronic aiming indicator overlaid upon a view of the target, the extrapolated aiming indicator position indicative of an attitude of the weapon suitable to have the hunting projectile strike the target. - View Dependent Claims (12, 13, 14, 15, 16)

17. An apparatus for generating an electronic aiming indicator a reticule on a display at a calculated reticule position, the calculated position being selected to indicate an attitude for a bow, the apparatus comprising:
-
the display mounted on the bow in an adjustably fixed relation and configured to selectively display a reticule and the electronic aiming indicator; 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 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, the rangefinder projecting from a bore-sight laser disposed in the projectile, a laser dot downrange along an axis; and a processor for extrapolating the calculated position for distances distinct from the known target distance based upon the bow speed, the known target distance and the reticule position the reticule being replaced on the display with the electronic aiming indicator in the calculated position. - View Dependent Claims (18, 19, 20)
