  • Figure 1 shows a unidirectional elliptical target that is created using concentric
  • the outer elliptical cylinder 101 is contiguous and is used to generate the first short circuit pulse need in determining the initial starting point of impact.
  • Each half of the inner elliptical cylinders are used to, in this orientation, determine the X location of impact. This is determined by looking at the time between the first and second impact of the inner elliptical cylinder. If the impact occurs in the center both halves of the inner elliptical cylinder will short simultaneously indicating an exact known X location. If the impact occurs between the outside of the inner elliptical sensor and inside the outer elliptical sensor then no pulses will be generated and the X position is either side of the target. By halving the outer elliptical cylinder similar to the inner elliptical cylinder the X position can be exactly determined.
  • the impact location is somewhere between the center and outer edge of the inner elliptical sensor then its X location can be determined by examining the time difference between the first and second pulse generated by the inner elliptical sensor.
  • the diagonal plate 103 is placed in such a way to generate a pulse needed to determine the Y location of impact. This is done by comparing the time difference between the first or second elliptical sensor pulse and comparing the predetermined velocity described above.
  • Figure 2 shows the top view of the unidirectional elliptical target.
  • the outer elliptical cylinder 201 and the inner elliptical cylinder 202 are spaced at a known distance.
  • the diagonal plate sensor 203 travels diagonally from the front side of the inner elliptical sensor to the back side of the inner elliptical sensor at the opposite end.
  • Figure 3 shows a timing diagram of how the pulses are used to derive the X-Y impact point.
  • the leading edge of the Outer Elliptical Sensor 301 and the leading edge of the Inner Elliptical Sensor 302 are used to determine the projectile's velocity.
  • the leading edge of the Diagonal Sensor 303 is used to determine the Y position of the impact.
  • the leading edge of the second pulse 304 on the Inner Elliptical Sensor is used to determine the X position of the impact. If you were to divide both the Inner & Outer elliptical sensor into smaller segments a more accurate X position as well as azimuth could be determined.
  • Figure 4 shows a Unidirectional target sensor system that is comprised of a front disk 401, a cone 402 segmented into four sections and a back disk 403.
  • the front disk and the back disk are spaced at a known distance and are used to determine the projectile's velocity.
  • the cone is used to determine both X and Y based on the time between the front disk pulse and the conic segment pulse.
  • the segment generating the pulse determines which quadrant the bullet hit and the time between the front disk and the conic segment pulses determines where within that segment that the projectile hit. Again if you were to divide the cone into smaller segments a more accurate X-Y location can be determined.
  • Figure 5 shows a top view of the Unidirectional Conic Target system.
  • FIG. 501 and the back disk 504 are placed at a known distance.
  • the upper left quadrant 502 and upper right quadrant 503 are positioned so that the projectile will enter and exit at a known angle making it easy to calculate both X and Y impact zone.
  • Figure 6 shows another embodiment of the same invention.
  • the front disk 601 has another disk 602 at a known distance behind it.
  • the conic sensor 603 is behind the second disk and determines the X-Y as in the previous embodiment.
  • Figure 7 shows the back view of the conic target system with four short circuit sensor segments upper right quadrant 701, upper left quadrant 702, lower right quadrant 703, and lower left quadrant 704.
  • Figure 8 shows an Omni-directional Cylindrical Target with contiguous outer 801 and inner 803 short circuit sensors placed at a known distance. Between both cylindrical sensors is a semi conic 802 short circuit sensor that is divided into two short circuit segments.
  • Figure 9 shows a top view of the Omni-directional Cylindrical Target.
  • Figure 10 shows a cutaway view of the Omni-directional Cylindrical Target.
  • the semi conic short circuit sensor 1002 Between the outer cylindrical short circuit sensor 1001 and the inner cylindrical short circuit sensor 1003 is the semi conic short circuit sensor 1002.
  • the slope of the sensor is calculated by measuring the distance across the top divided into the length vertically of the sensor. This sensor is used to determine the Y position of impact. As you can see when a projectile enters the target that has a trajectory path through the top of the target 1004 it will generate pulses, when comparing outer ring sensor to semi conic secondary ring, closer together then a projectile traveling through the bottom of the target 1005.
  • Figure 11 shows a multi segmented embodiment of the previous invention.
  • the outer cylindrical short circuit sensor 1101 and inner cylindrical short circuit sensor 1103 are again placed at a known distance needed to calculate projectile velocity.
  • the semi conic short circuit 1102 sensor is placed between the outer and inner cylindrical sensors and is used to determine the Y position of the projectile.
  • FIG 12 shows a top view of the segmented Omni-directional cylindrical target.
  • the outer cylindrical short circuit sensor 1201, semi conic short circuit sensor 1202 and inner cylindrical short circuit sensor 1203 have all been divided into four segments and offset by 30 degrees.
  • This target has the ability to more accurately determine the X position than the previous embodiment.
  • a projectile hits the outer ring which ever segment is hit determines the first X position approximation of entry.
  • the semi conic sensor is hit the second X approximation is determined and finally when the inner ring is hit the third X approximation can be easily determined.
  • the azimuth is also easily determined.
  • the Y position of impact can also more accurately be determined due to the fact that an accurate azimuth can be calculated.
  • Figure 13 shows a cutaway view of the current invention.
  • the outer cylindrical short circuit sensor 1301, semi conic short circuit sensor 1302, and outer cylindrical short circuit sensor 1303 are all segmented and shifted by 30 degrees. More than four segments can be used to achieve a more accurate position location of impact without deviating from the current invention.
  • each of the inner side of each sensor can be manufactured as a single contiguous sheet of conductive material/foil or tied to each other so that only 1 wire is needed to power/sense all 3 sensors on the inner side.
  • Figure 14 shows another embodiment used to reduce the amount of wires needed to sense the segmented Omni-directional cylindrical target.
  • a resistive rubber strip 1401 is bonded with conductive adhesive to the outer conductive sheet/foil/ink of each sensor.
  • the outer cylindrical short circuit sensor 1403 is bonded to all segments and has a gap 1402 between 2 adjacent segments.
  • the resistive rubber strap does not have to be contiguous. It can be segmented into smaller strips that just jumper three of the four gaps. Now only one wire needs to be attached to each outer conductive sheet/foil/ink.
  • the resistive rubber would take a projectile impact and only change its resistance by a small amount, if any, due to its self healing properties.
  • Figure 15 shows the inner cylindrical short circuit sensor with the resistive rubber strip encompassing all but one gap 1501. Notice the opposite gap 1502 is bridged with the resistive rubber.
  • the projectile shorts the conductive sheets/foil/ink a short is detected across only the segment that the sense wire is attached to. All other segments show up as a resistance increasing as you move away from the segment with the sense wire attached. If the segments where wired so that the left most segment 1503 was directly attached to the sense wire and the next clockwise segments, 1504, 1505, 1506 were bridged across each gap with the resistive rubber, the resistance would increase as you move clockwise away from the left most segment.
  • FIG. 16 shows a simulated circuit that displays the response of such a system. Notice that the pulse edges on the oscilloscope 1601 are well defined and can easily be used to determine velocity and Y position.
  • the relays 1602 and capacitors 1603 emulate the sensor conductive sheets/foil/ink and insulator.
  • the digital word generator 1604 fires the relays in successive order and the oscilloscope show each pulse maximum voltage level is increasing as you move toward the sensor wired to the sense wire that is connected to the sense resistor 1605.
  • a sense resistor is used to create a resistive divider network that can detect the change in resistance of the short circuit sensor. Therefore it is obvious to see that both the time of impact, from the leading edge of the pulse, and sensor segment impacted, from the amplitude of the pulse, can be determined from such a circuit.
  • the outer resistive rubber strap had a gap resistance of 100 ohms with a 100 ohm resistive rubber strap connected to the next inner semi conic ring and the semi conic ring had a gap resistive rubber strap of lk ohms with a lk ohm resistive rubber strap connected to the inner most cylindrical segmented short circuit sensor which in turn had a resistive rubber strap with a gap resistance of 5k ohms a two wire target could be created.
  • the Inner ring segment 3 Upon exiting the target the Inner ring segment 3 would be hit presenting a sense resistance of 14.4k ohms. Next the Semi Conic ring segment 2 would be hit presenting a sense resistance of 14k ohms. Finally as it exits the Outer Ring segment 2 a sense resistance of 100 ohms would be presented on the sense wire. So the projectile trajectory can easily be reconstructed simply by looking at the analog voltage levels combined with the leading edges of the pulses generated by each segment.
  • Figure 17 shows an Omni directional target that has the ability to not only determine X-Y but azimuth and elevation as well.
  • the target is comprised of an outer cylindrical short circuit sensor 1701, inner cylindrical short circuit sensor 1702 and a multi segmented sphere 1703.
  • the sphere short circuit sensor gives the ability to detect X-Y entry and exit points and it can be used to determine both azimuth and elevation of projectile trajectory path.
  • Figure 18 shows the top view with the outer cylindrical short circuit sensor 1801 and the inner cylindrical short circuit sensor 1802 being spaced at a known distance.
  • the inner sphere 1803 is segmented in both four quadrants and in half creating an eight segmented sensor as shown in Figure 19.
  • Resistive rubber interconnections could be used to allow you to attach only one sense wire attached to only one of the segments. For example: the upper leftmost segment 1901 was directly wired to the sense wire and the resistive rubber strip traversed clockwise across the entire upper half 1902, 1903, 1904 then dropped down to the lower half 1905 and traverse counter clockwise ending on the front lower

  • the sensor can also be a purely resistive ink/foil sensor that has two conductive busses running up the outer sides vertically and when hit the resistance will change. That change can be detected by the sense resistor circuit show in Figure 16.
  • the same configuration can be used for thermal heaters to produce a thermal signature.
  • the chest heater can be configured to produce a temperature 10 degrees above ambient while the head heater can be designed to produce a temperature of 20 degrees above ambient generating a human thermal signature.

  • Figure 29 shows another embodiment of the invention with a cylindrical kill zone sensor 2901 running down the center of the target. If a short circuit is detected on this sensor a kill shot can be scored by the target acquisition system.
  • Figure 30 shows another embodiment of this invention having the short circuit or resistive sensor wrapped around the entire torso. Each sensor chest 3001, shoulder 3002, and head 3003 are wrapped entirely around the torso to allow for 360 degrees of impact detection. A thermal heater could be produced in this configuration as well to give a 360 degree human thermal signature.

  • the outer sensor 3601 and inner kill zone sensor 3603 are spaced a known distance apart and have a semi conic cylinder sensor 3602 between them.
  • Figure 37 shows the top view of the current invention embodiment and again all the rings are divided into 4 rings and offset by 30 degrees.
  • Figure 38 shows the cutaway view of the Omni directional X-Y target. You will notice that the distance from the inner semi conic elliptical sensor to the elliptical cylinder sensor varies from the bottom 3801 of the torso to the top 3802. This slope is used to determine the Y position of impact. Now in this embodiment the shoulder has no vertical reference need to determine the Y position of impact. A series of segmented cascaded elliptical cylinder sensors that stair step their way up the inside of the shoulder cavity 3803 could be used to create that vertical reference.
