Bow sight
First Claim
1. A sighting device for mounting on an archery bow for aiding an archer to fire an arrow toward a target at a distance from the bow, said device comprising a housing for mounting on the bow, electrical circuit means including an electrical circuit board carried by said housing, said electrical circuit means comprising a source of electrical energy, a plurality of light emitting elements mounted on said circuit board in an aligned array, a tilt sensor connected in said circuit means carried by said housing and having a substantially linear electrical output responsive to angular inclinations of said bow, electrically programmable memory, means for storing in said memory a pre-selected range of values representative of angular inclinations of the bow in a vertical plane extending from said bow toward said target, means for permitting a selective portion of said range of values to be assigned to correspond to each light emitting element selectively and for storing into said memory the selective portion of said range for each corresponding light emitting element, and means responsive to the output of said tilt sensor for comparing the angular inclination of the bow with the portions of the range in said memory to determine the portion of the range corresponding to the angular inclination of the bow and for lighting the light emitting element corresponding thereto.

Abstract
A bow sight includes a housing which is mounted on an archery bow and carries electronic circuitry including a series of aligned target LED'"'"'s which may be programmed by an archer to correspond to different respective target distances. The housing mounts a color separating dichroic filter sight glass positioned at an angle between upper and lower housing walls. The LED'"'"'s are positioned to overlay an elongated slot in the top wall so that a lighted LED reflects onto a surface of the glass and may be viewed for sighting a target. Two other LED'"'"'s, one on each side of the target LED'"'"'s, are included in the circuitry and may be programmed to light when the bow is tilted to a selected side-wise position, apertures in the top wall of the housing permitting reflection of each of these LED'"'"'s onto the sight glass. After each target LED have been programmed, the archer may sight through the sight glass and align the reflection of the lighted target LED onto the target.

15. A method of accurately firing an arrow from an archery bow toward a target at a distance from the bow, said method comprising providing a sighting device having an electrical circuit including a plurality of aligned light emitting elements, selecting one of said light emitting elements to light when said arrow is fired a first distance from said bow, storing in an electrically programmable memory corresponding to said one of said light emitting elements a value equal to the angular disposition of said bow in a vertical plane providing said first distance, repeating said selecting and said storing for each of the other light emitting elements in seriatim to store in said memory respective angular disposition values corresponding to respective distances, viewing the target through a sight glass on which a reflection of said light emitting elements may be seen when any of said light emitting elements are lighted, and thereafter aiming at said target and firing said arrow when one of said light emitting elements is seen on said glass in superposed relationship on said target.
