Method and apparatus enabling archery practice
First Claim
1. A method providing archery practice simulating a dynamic target scene as in an animal hunt, wherein an arrow is shot toward a screen, comprising the steps of:
- providing a screen having a front and a back;
providing an arrow having a tip, wherein penetration of said screen by said arrow tip is avoided when said arrow tip hits said screen;
projecting target scenes in sequence on said front of said screen for viewing as a dynamic target by an archer;
determining an arrow hit location relative to said screen showing a first target scene using said arrow shot by the archer;
permitting said arrow to fall from said screen between the archer and said front of said screen; and
informing the archer of said arrow hit location.

Abstract
An archery practice device projects a moving hunt scene on a screen. In one embodiment of the invention, a continuous plane of IR light is located prior to the screen, an arrow carrying a reflector is detected as it penetrates this light plane, and IR illumination is reflected back toward the archer and a full-screen radiation detector. In another embodiment, a piezoelectric motion detector senses impact of an arrow on the screen, an IR source is momentarily triggered by the motion detector, and IR illumination is reflected by the arrow toward the full-screen radiation detector. The detector generates a full-screen signal indicating the point of arrow impact on the screen. Upon detecting the arrow, the moving scene is frozen on the screen. The visual content of the frozen scene is coordinated to the full-screen signal from the detector, whereupon a hit zone image is projected on the screen to indicate the arrow impact point relative to the frozen scene. The arrow does not penetrate the screen, and drops vertically downward adjacent to the bottom of the screen at a location between the front of the screen and the archer.

9. Apparatus for simulating a moving hunt scene for an arrow shot by an archer, comprising:
-
a screen having a front and a back; means projecting a sequence of visual frames comprising said moving hunt scene onto said front of said screen for presenting at least one hunt object visible to the archer; means for determining an arrow hit location relative to said screen showing a first visual frame using an arrow shot by the archer; and means for informing the archer of said arrow hit location; wherein said screen is constructed and arranged to avoid penetration thereof by the arrow and the arrow falls from said screen between the archer and said front of said screen. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. Apparatus providing a visual moving scene toward which an arrow shot by an archer is directed, comprising:
-
a screen having an imaging and arrow stopping surface; an arrow having a leading end that is constructed and arranged so as to not penetrate said surface; means projecting a sequence of visual scenes onto said surface, said sequence of visual scenes presenting at least one moving target for an arrow; sensing means for sensing the position of an arrow as it approaches said surface and a given scene projected thereon; determining means responsive to said sensing means for determining an arrow hit location on said surface; means responsive to said sensing means for freezing said given scene on said surface for viewing by an archer; and means responsive to said determining means for projecting said determined arrow hit location on said surface for viewing by an archer along with said given scene.

23. Apparatus simulating an archery hunt scene having at least one moving object, comprising:
-
a screen having an arrow stopping surface of a size simulating a hunt area normally viewed by an archer; an arrow having a nonpenetrating leading end; means projecting a sequence of visual hunt scene frames onto said arrow stopping surface for viewing by the archer; sensing means responsive to an arrow approaching said arrow stopping surface for determining a subsequent arrow hit location on said arrow stopping surface; means responsive to said sensing means for freezing a visual hunt scene frame on said arrow stopping surface for viewing by the archer; and means responsive to said sensing means for projecting said determined arrow hit location on said arrow stopping surface for viewing by the archer. - View Dependent Claims (24, 25, 26, 27, 28)
