The disclosure relates generally to an apparatus for generating targets; specifically, an apparatus generating vitals targets that measure accuracy for a plurality of different distances.
Marksmanship is vital in a number of different sports. Whether it be hunting, shooting, air guns, or archery, marksmanship is used to measure skill and prowess. Marksmanship is also used to prepare for ethical hunting expeditions.
Individuals practicing marksmanship may do so at a practice range allowing for practice at a known distance. Practice ranges may not include the distance required during a hunting expedition. Individuals may estimate the skill needed for an ethical hunting expedition as it correlates to the distance available for a practice range.
When an individual is not sufficiently practiced to be accurate at the distance used in the hunting expedition the animal hunted may not be ethically harvested.

The image of an animal indicating an animal that may be hunted is disclosed. Each of the plurality of vital zones indicates the vital zone of an animal to strike for a humane hunt. The amulets may be the area between two vital zone outlines. The amulets may represent the difference in grouping size used for an ethical hunt.
A more particular description of the invention briefly described above is made below by reference to specific examples. Several examples are depicted in drawings included with this application. An example is presented to illustrate, but not restrict, the invention.
A detailed description of the claimed invention is provided below by example, with reference to examples in the appended figures. Those of skill in the art will recognize that the components and steps of the invention as described by example in the figures below could be arranged and designed in a wide variety of different configurations, without departing from the substance of the claimed invention. Thus, the detailed description of the examples in the figures is merely representative of an example of the invention and is not intended to limit the scope of the invention as claimed.
In some instances, numerical values are used to describe features such as spreading factors, angle, trajectory, and distances. Though precise numbers are used, one of skill in the art recognizes that small variations in the precisely stated values do not substantially alter the function of the feature being described. In some cases, a variation of up to 50% of the stated value does not alter the function of the feature. Thus, unless otherwise stated, precisely stated values should be read as the stated number, plus or minus a standard variation common and acceptable in the art.
For purposes of this disclosure, the modules refer to a combination of hardware and program instructions to perform a designated function. Each of the modules may include a processor and memory. The program instructions may be stored in the memory and cause the processor to execute the designated function of the modules.
Identifying and targeting a vital zone is a valued skill for marksmen and hunters. The vital zone for any animal may be shaped in three dimensions. While the vital zone may be irregularly shaped, it may be represented by a circle, triangle, rectangle, oval, oblong, or other shapes including irregular shapes within the vital zone area that provides proper shot placement for an ethical hunt. Scoring of a target may include that all shots are placed within a vital zone.
A purpose of the claimed apparatuses, methods, and systems is to facilitate and enhance the use of a computing device. One example of the apparatus is a computer with a printer used to generate vitals targets that can be used at a marksmanship range when the apparatus is not present. Another example is a computer program product used to generate vitals targets that are used at a marksmanship range. Yet another example is an apparatus for training marksmanship that includes a target. The target includes an image of an animal, a plurality of vital zones, and a number of amulets. The target can be used at a known distance to simulate the accuracy needed for an ethical hunt at a different distance.
As used in the present specification, projectile refers to an object being propelled from a device, such as a firearm, air gun, or a bow and arrow, toward a target.
As used in the present specification, ammunition refers to a projectile, a powder charge, and an ignition source. When the ignition source is activated it ignites the powder charge which causes the projectile to be expelled from a firearm.
As used in the present specification, modern ammunition refers to ammunition that has a projectile, a powder charge, a case, and a primer. The primer is the ignition source for the powder that is activated by pressure. The primer ignites the powder charge. The ignited powder charge is contained by the case, causing the expanding gases to propel the projectile out of a firearm.
As used in the present specification and in the appended claims, ballistics coefficient refers to a numerical value effecting the flightpath of a projectile.
As used in the present specification and in the appended claims, vitals zone refers to a target area of an animal representing the vital organs. If the vital zone of an animal is hit by a projectile, it is most likely to cause the quick death of the animal which prevents the animal from suffering unnecessarily.
As used in the present specification and in the appended claims, muzzle refers to the end of a barrel of a firearm from whence a projectile is expelled.
As used in the present specification and in the appended claims, trajectory refers to the flightpath of a projectile between the time it is released from a device and its position during flight. The trajectory may be affected by the speed of the projectile, the ballistic coefficient, and gravity.
As used in the present specification and in the appended claims, a number refers to a whole number of the value one or greater, zero, not being a number, but rather being the absence of a number.
As used in the present specification and in the appended claims, plurality refers to two or more of an item.
As described above, an apparatus for generating a vitals target allows for a marksman to practice a plurality of distances at a shorter distance for receiving feedback as to the accuracy required for longer distance. Additionally, a marksman may measure improvement over time and identify a distance where the marksman can engage in an ethical hunt. By being able to readily practice a variety of distances and vital targets, marksmen may improve their skill for ethical hunting. Ethical hunting may improve the survival rates of a number of species effected by ethical hunts. An ethical hunt may reduce the burden of one species on an area of land, which allows for other species to flourish. An ethical hunt may be used to reduce predators in an area, allowing an endangered species to grow and populate an area.
For example, if there are too many deer in an area, the deer may over consume vegetation resulting in insufficient vegetation for other species. Additionally, the overconsumption of vegetation may cause the deer in an area to become ill or sickly due to the unavailability of food. The overconsumption of vegetation may cause erosion due to the lack of vegetation, which may have permanent and lasting effects on land usage. An ethical hunt may control the population of the species, to allow other species, and/or even that species to populate the area.
Marksmen may find it easier to practice accuracy and learn vital targets at a structured shooting range, where marksmanship is practiced and measured under known conditions and known distances. A marksman may choose the practice arena, as it allows for greater frequency of shots and better feedback on each individual shot. Thus, over time a marksman may improve faster in a structured practice area than in a hunt. Additionally, a marksmen that engages in practice is less likely to cause pain and suffering for an animal through a missed or poorly placed shot.
Additionally, some marksmen prefer to show off their accuracy and prowess without engaging in hunting. Such simulated activities may provide for entertainment and enjoyment while measuring a valuable skill, whether or not that skill is actually used in hunting.
The disclosed target may be adapted to simulate the relative vital size of different animals at different distances. For example, an animal with a vital size of substantially ten inches when viewed from 100 yards may appear to be substantially five inches when viewed from 200 yards.
In the preferred embodiments, the target may have multiple rings. In the preferred embodiments the target may have six concentric rings with a bullseye located at the center of each of the rings. The outer ring may be the ring with the longest diameter, the second ring may be the ring with the second longest diameter, the third ring may be the ring with the third longest diameter, the fourth ring is the ring with the fourth longest diameter, the fifth ring is the fifth ring with the fifth longest diameter, and the sixth ring is the sixth ring with the sixth longest diameter. The target may have anywhere between one ring and one hundred rings.
In some embodiments, the outer ring may correspond to a ten inch vital diameter and may have a length correction equal to ten inches divided by 1.047. In some embodiments the length correction is determined by dividing by 1.047. The 1.047 figure may be determined by using an angle subtended multiplied by 0.95493. An inverted or reciprocal of “1 MOA” at 100 yards, which is 1/1.047, may be used to confirm the diameter or dimensions of the ring representing the area of an animal's vitals as viewed from 100 yards; a bullet spread calculation may be used to confirm that the concentric rings reflect the shooters accuracy at the long distances.
In the preferred embodiments, a target also has one or more horizontal lines to provide a guide. In the preferred embodiments, a target may have three horizontal lines; the first line may represent a 2 inches sight mark; the second line may represent a 3 inch sight mark; the third line may represent a 4 inch sight mark. In some embodiments, a first horizontal line is positioned 2 inches below the horizontal center line of the target; in other embodiments, a second horizontal line is paced 3 inches below the horizontal center line of the target; in some embodiments a third horizontal line is placed 4 inches below the horizontal center line of the target; in some embodiments, a target may have a first horizontal line, a second horizontal line, and a third horizontal line. For one or more of the horizontal lines, a vertical line may be positioned perpendicular to the corresponding horizontal lines. This vertical-horizontal line may allow a shooter to align his or her scope both horizontally and vertically. This vertical-horizontal line may be useful to the shooter so that the shooter may aim at the target without having to tilt his or her scope since tilting may impact the shooter's accuracy. The target may be used by a shooter made to measure one's accuracy and may also be used by a shooter to improve the shooter's accuracy. A hunter with a gun sighted to be 2 inches high at 100 yards may then aim for the 2 inch horizontal mark and may be more likely to hit the target substantially near the center of the bullseye. The 2 inch horizontal mark is positioned so that a hunter with the gun sighted to be 2 inches high at 100 yard should, if all other factors are controlled, may then be more likely to hit the target substantially near the center of the bullseye.
A hunter with a gun sighted to be 3 inches high at 100 yards may then aim for the 3 inch horizontal mark and may be more likely to hit the target substantially near the center of the bullseye. The 3 inch horizontal mark is positioned so that a hunter with the gun sighted to be 3 inches high at 100 yard should, if all other factors are controlled, may then be more likely to hit the target substantially near the center of the bullseye.
A hunter with a gun sighted to be 4 inches high at 100 yards may then aim for the 4 inch horizontal mark and may be more likely to hit the target substantially near the center of the bullseye. The 4 inch horizontal mark is positioned so that a hunter with the gun sighted to be 4 inches high at 100 yard should, if all other factors are controlled, may then be more likely to hit the target substantially near the center of the bullseye.
The targets may have a written explanation for how to measure one's effective range using a five shot parameter for the number of shots needed to determine a true shooting pattern and use this as a measurement system. A method of use may include shooting a certain percentage of bullets into a certain ring to help determine ethical effective range of the shooter and shooting position.
In some embodiments, an outer ring of the target has a diameter; the diameter of the outer ring of the target may be associated with a shooting distance such as 100 yards at which a shooter may shoot from to simulate shooting at the vital area of a certain species of animal. For example, the diameter of a ring of the target may equal ten inches; the diameter of a ring of the target may simulate the relative size of an antelope's vital area as viewed by a shooter who is located substantially 100 yards from the target. Additional distances may be associated with different diameters of different rings.
Referring now to the figures,
The computer system (101) may include a processor (102), memory (104), a network interface card (106), and an output device card (108) that are communicatively connected through a communication bus (110) with a non-transitory storage medium (120).
The non-transitory storage medium (120) may include a number of modules (121). The number of modules may include a combination of software, hardware, or both to perform a particular task. In this example, the non-transitory storage medium (120) may include a target distance module (121-1), a target animal module (121-2), a vital zone module (121-3), a first distance module (121-4), a target calculate module (121-5), an output generate module (121-6), a second distance module (121-7), a direction determine module (121-8), and a trajectory calculate module (121-9).
The target distance module (121-1) calculates a distance at which the vital zone target may be used at. The target distance module may generate a target based on a common distance for practicing marksmanship. For example, in handgun marksmanship, popular distances may include 7 yards, 10 yards, 15 yards, 17 yards, or 25 yards. Similar distances may be calculated using metric values. In another example, in rifle marksmanship popular distances may include 25 yards, 50 yards, 100 yards, and 200 yards. The target distance module (121-1) identifies one target distance where the target is designed to be used.
The target animal module (121-2) identifies an animal for which a vital zone will be selected. For example, the target animal module (121-2) may identify a wild boar as the target animal. In another example, the target animal module (121-2) may identify an elk, deer, bear, turkey, elephant, lion, mountain lion, or other animal which may be targeted.
The vital zone module (121-3) identifies the vital zone of the animal identified by the target animal module (121-2). Each animal may have a different vital zone. Further, the vital zone may actually be representative of a three-dimensional space in the animal where the vital organs are most likely to be. Identifying the vital zone may require identifying an angle at which the target animal may be presenting itself in relationship to the marksman. The vital zone module (121-3) may use infrared sensors to determine the vital zone based on heated areas of an animal. A three-dimensional vital zone may be represented in two dimensions by showing the outline of the vital zone from a desired perspective.
The first distance module (121-4) may identify a first distance to be emulated at the target distance. For example, a target distance of 50 yards may be identified. The first distance module (121-4) may identify a target distance of 100 yards. The target generator (100) may then use various calculations to represent the accuracy needed at 50 yards in order to hit the vitals zone at 100 yards.
The target calculate module (121-5) may calculate the size of the target based on a combination of the target distance, the vital zone, and the direction an animal is being emulated stand. The target calculate module (121-5) may consider the trajectory of a projectile in identifying the target size.
The target calculate module (121-5) may calculate the size of the target at the by taking a point from whence the projectile may be released to a figurative vital zone target at the simulated distance. Geometric calculations may then measure the angle from the point of release to the outer edges of a two-dimensional vital zone. Mathematical formulas, such as the Pythagorean Theorem, may be used to calculate the size of the target at the target distance.
The output generate module (121-6) may create output that a marksman may use for marksmanship practice. In one example, the output generate module (121-6) may cause a printer associated with the computer system (101) to print a target that may be used by the marksman. In another example, the output generate module (121-6) may control an input and output device that causes a target to be projected in front of a marksman while measuring a simulated projectile from the marksman. In yet another example, the output generate module (121-6) may control an output device that projects a virtual target in front of the marksman. A sensor may be used to read where an actual projectile from the marksman strikes the projected target.
A second distance module (121-7) may calculate a second distance for which a vital zone may be represented on a single target. For example, a target distance of 50 yards may have a vital zone presentation for both 50 yards and 100 yards. Additional distances may be identified by the second distance module (121-7).
A direction determine module (121-8) may determine the presentation direction of a target animal in relation to the marksman. The direction the animal is facing may determine the two-dimensional shape of the vital zone as presented to the marksman. For example, the direction determine module (121-8) may determine that an animal is looking straight at the marksman. The animal looking straight at the marksman may present a particular shape of the vital zone. In another example, the animal is facing away from the marksman at a 90° angle in what is called a broadside shot. This may present a different shape of the vital zone.
The target generator (100) may use a trajectory calculate module (121-9) which considers the trajectory of a projectile. The trajectory calculate module (121-9) may consider the variance in angle from which a projectile is expelled. The trajectory calculate module (121-9) may consider the ballistic coefficient of the projectile. The trajectory calculate module (121-9) may consider the effects of gravity on the projectile over time during the flight of the projectile.
An overall example according to
A target animal is identified by the target generator (100) using the target animal module (121-2). A target animal of a male white-tail deer is identified.
A vital zone is identified by the target generator (100) using the vital zone module (121-3). A three-dimensional understanding of the vital zone of a male white-tail deer may be identified.
A first distance at the first distance when being shot at the target distance. The first distance may be the target distance or the first distance may be different than the target distance. In this example, the first distance module (121-4) identifies 50 yards as the first distance being simulated.
A second distance is identified by the target generator (100) using the second distance module (121-7) to determine the size of the vital zone as though the vital zone is at the second distance when being shot at the target distance. In this example, the second distance module (121-7) identifies 100 yards as the second distance being simulated.
A direction of the target animal may be identified by the target generator (100) using a direction determine module (121-8). In this example, the direction determine module (121-8) identifies that the animal is facing to the right of the marksman, providing a broadside shot.
A projectile trajectory may be calculated by the target generator (100) using the trajectory calculate module (121-9). The projectile trajectory may be used in calculating the size and placement of the target.
A target shape and size may be determined using the target calculate module (121-5). In this example, the target calculate module calculates a vital zone target for 50 yards and 100 yards as sized to be aimed at 50 yards. The projectile trajectory may be used to place the targets to account for the gravitational drop and projectile angle as varied between 50 yards and 100 yards.
In this example, a number of vital zone targets (2300) are illustrated. In this example, the vital zone targets (2300) are concentric and may represent the accuracy needed by a marksman to hit a vital zone at a given distance. The area between vital zones may be referred to as an amulet. The size of the amulet may be measured in the distance between a plurality of vital zones. The distance between vital zones may vary significantly depending on the distance the vital zone represents. An overall example using
Each of the vital zone targets (2300) may represent a vital zone at a given distance. In this example, the vital zone target (2300) is being presented at 25 yards. The first vital zone (230-1) may represent the vital zone at 25 yards. The second vital zone (230-2) may represent the accuracy needed by the marksman for an effective shot at 50 yards. The difference in the targets may create an amulet distance (231-1) that represents the increased accuracy needed to hit the vital zone target (2300) at the longer distance.
The third vital zone (230-3) may represent the vital zone at 100 yards. The amulet distance (232-2) between the second vital zone (230-2) and the third vital zone (230-3) may represent the increased accuracy needed to strike the vital zone at 100 yards.
The shooting position (309) may represents the barrel of a firearm. The path of the projectiles may be determined by slight variances in the barrel and the muzzle of the firearm. Minor variances at the shooting position (309) may have significant effects over a long distance. For example, a non-discernible variation in the shooting position may be unmeasurable at 7 yards, but may provide for a target miss at distances over 1000 yards.
The angle of movement (311) of the shooting position (309) may cause these variations. The angle of movement is a two-dimensional angle that includes both left and right and up and down components. One may think of the angle of movement as creating a cone in which the projectile will travel when released. Marksmen spend a great deal of time and effort reducing the size of the angle of movement (311). Additionally, the device used, such as a firearm, may affect the angle of movement. Some marksmen will expend significant time, money, and resources minimizing the angle of movement.
The measurement of the angle of movement may be measured in minute of angle, or MOA. An MOA represents a movement of 1/60th of a degree.
At close distances, the angle of movement may have minor effects. For example, the size of the target zone at a known first distance (320-2) may create a target zone (322-1). At a longer distance (320-3), a larger target zone (322-2) occurs. At a still longer distance (320-4) an even larger target zone (322-3) occurs.
The first target (340-1), second target (340-2), and third target (340-3) may be presented as shaded or line art on paper for a target. In this example the outline of the first target (340-1) is illustrated as a ring (441-1). The outline of the second target (340-2) corresponds to a different ring (441-2). The outline of the third target (340-3) corresponds to yet a different ring (441-3). The number of rings create a number of amulets, which may have different distances between them. The different distances represent the improved level of accuracy necessary to strike the fixed size target at the varying distances. Additionally, the rings may or may not be circular, but may also represent the outline of the vital zone that has been selected by the target generator (100). The rings may be a circle, triangle, rectangle, oval, oblong, or other geometric shapes including irregular shapes.
The target generator (100) may consider the effects of the trajectory and drop of the projectile in creating the vital zone target (2300).
The animal silhouette (970) may be used to identify the vital zones (230) of the animal being targeted. The animal silhouette (970) may also illustrate the simulated angle of the animal in relationship to the marksman. The animal silhouette (970) may illustrate the placement of the vital zone (230) in relationship to the animal. The vital zone (230) may be to scale with the animal, or the animal may be at a different scale than the vital zone targets.
The number of amulets (933) may vary in size and area, based on the illustrated distance of the vital zones (230). The amulets (933) may be shaded or colored to illustrate which vital zone is appropriate for which distance.
The non-transitory storage medium (1010) includes a target distance identifier (1021-1), a target animal identifier (1021-2), a vital zone determiner (1021-3), a first distance identifier (1021-4), a second distance identifier (1021-5), a direction determiner (1021-6), a target calculator (1021-7), a trajectory calculator (1021-8), and an output generator (1021-9).
The target distance identifier (1021-1) identifies a distance at which the target may be used at. The target distance will affect the size of the target presented to a user.
The target animal identifier (1021-2) identifies an animal for which a vital zone will be simulated.
The vital zone determiner (1021-3) identifies the three-dimensional attributes of the vital zone of the animal which will be simulated.
The first distance identifier (1021-4) identifies a first distance to be simulated at the target distance for the vital zone of the animal identified.
The second distance identifier (1021-5) identifies a second distance to be simulated at the target distance for the vital zone of the animal identified.
The direction determiner (1021-6) identifies the direction of the animal identified in relationship to the marksman that will be using the target. For example, the direction determiner (1021-6) may identify the animal as looking to the left, right, at a 45° angle, or straight at the marksman.
The target calculator (1021-7) calculates the shape of the vital zone at the angle determined for the animal identified at the distance simulated for the target distance.
The trajectory calculator (1021-8) may calculate the trajectory of a projectile to determine the placement of a number of vital zone targets.
The output generator (1021-9) causes the device to generate a vitals target. The output generator may generate a vitals target with a plurality of vital zones. The vital zones may have a plurality of different center points based on a trajectory calculation by the trajectory calculator (1021-8). The output generator may generate an overlay image of the animal corresponding to the vitals target. The overlay image may be used to identify the vitals target.
A shooter may want to simulate shooting from a determined distance and have the target circles represent the size of the vitals at the shooting distance determined for a set further distance for multiple animals. An example would be a target set at 100 yards with the circles representing the size of vitals at 200 yards. Each animal vital circle would be used starting with the largest vital circle to the smallest. The sizes of these vital circles are determined by Angle Subtended and 1/n formulas. Representative data is illustrated in
In the preferred embodiments when the outer ring is 10 inches and the outer ring corresponds with a 100-yard distance, then a division factor of 2 may be used for a second ring that may be associated with a 200 yard simulated shooting distance since 200 yards divided by 100 yards equals 2. Then, dividing the actual distance of the diameter of the outer ring by the multiplication factor of 2 may be calculated as follows: 10 inches/2=5 inches in diameter for the second ring. Other simulated distances may be used, and other diameters of associated rings may be used. Additionally, the diameter of the associated ring may also undergo a correction adjustment, such as being divided by 1.047, or multiplied by 0.95493. All references may be calculated using an angle subtended, such as with the following formula: diameter=2 arctan r/R. One may then convert to radians, degrees, or arcs. Thus, in the preferred embodiments, when a vital area of an animal is determined to be 10 inches, such as 10 inches, at a 100 yard simulated shooting distances, then the 10 inches may be divided by 1.047 (multiplied by 0.95493) for the actual diameter of the outer ring. The second ring may then be associated with a simulated shooting distance of 200 yard, the division factor would then be 2, and the diameter of the second ring would then be the adjusted size of 10 inches×0.95493 divided by 2.
The third ring may then be associated with a simulated shooting distance of 300 yard, the division factor would then be 3, and the diameter of the third ring may then be 10 inches/1.047/3. (10*0.95493/3). The 10 inches could be any length that is associated with the vital area of an animal that may be hunted legally or illegally by humans.
The fourth ring may then be associated with a simulated shooting distance of 400 yard, the division factor would then be 4, and the diameter of the second ring would then be 10 inches/1.047/4. (10*0.95493/4).
The fifth ring may then be associated with a simulated shooting distance of 500 yard, the division factor would then be 5, and the diameter of the second ring would then be 10 inches/1.047/5. (10*0.95493/5).
The sixth ring may then be associated with a simulated shooting distance of 600 yard, the division factor may then be 6, and the diameter of the second ring may then be 10 inches/1.047/6. (10*0.95493/6).
The reduction in size of a vital area by 1/1.047 may be determined by a bullet spread calculation. With the bullet spread calculation, one may determine the angle at 100 yards that one must shoot at to shoot a bullet within one of the rings and how this angle relates to the vital size of an animal at distances longer than 100. Using a measure of angle, the targets may be configured for bullet spread grouping. The bullet spread calculation using MOA at one hundred yards mathematically may match the Angle Subtended calculation and both follow the 11/N formula for the concentric rings. The bullet spread calculation sheet may allow one that is focused on MOA to confirm that the target circles are giving them the same results. See
A bullet spread calculation may use 1 MOA at 100 yards to confirm 100 yard target size then extrapolate the spread as yardage increases. This spread number may be compared to 100 yard target size. A shooter may then shoot a series of bullets at the target, such as 5 bullets. The shooter may then count the hit number, the hit number being the number of bullets that contact the target within a certain ring; the shooter may then compare that hit number to threshold data in a bullet spread column; when a hit number is equal or greater than the corresponding threshold data, a shooter may then confirm his or her ethical shooting range.
With the bullet spread calculation, one may determine the angle at 100 yards that one must shoot at to shoot a bullet within one of the rings and how this angle relates to the vital size of an animal at distances longer than 100.
In some embodiments the target has a bullet grouping not only defined by the largest distance between where the bullet hits on the target but also the largest difference from a bullseye to the furthest bullet hole. This measurement may be used when calculating bullet spread. See
In some embodiments, the concentric vital circles may be determined by Measurement of Angle bullet spread.
