Description

LASER ALIGNMENT SYSTEM FOR SHORT ARMS TECHNICAL FIELD The present invention relates to military training equipment, especially, with a system for automatically aligning a laser transmitter in a rifle to be used subsequently by a soldier in war drills.
BACKGROUND For many years the armed services of the United States have trained soldiers with an integrated multiple battle laser system (MILES). A laser transmitter for handguns (SAT) is attached to the case of a rifle such as MI6. Each soldier carries detectors on his helmet and a body harness adapted to detect the target of a laser "bullet". The soldier pulls the trigger of his rifle to hit the target and simulate a real shot, and an audio sensor triggers the SAT. It is necessary to align the SAT so that the soldier can hit the target with precision once he or she has placed it in the sights of conventional rifles. In the past the previous version of the SAT was linked by a bolt to the rifle's case and the mechanical sight of the weapon was adjusted to be aligned with the laser beam. The disadvantage of this procedure is that you have to readjust the mechanical sight of the weapon to be able to use the rifle in real shots. To overcome this disadvantage, the conventional SAT that is currently used incorporates mechanical joints to change the orientation of the laser.
The prior art of the short weapons alignment devices (SAAF) used by the United States Army to align the conventional SAT MILES is formed by a complex set of one hundred and forty-four detectors, which are used along with thirty-five printed circuit boards to determine where the laser will hit the target in relation to a reticular target. The difficulty of using the previous SAAF technique is that the soldier points his weapon at the grid that is twenty-five meters away without the use of a stable platform. In many cases, the soldier fires his weapon in a way that results in the target not being in the desired location. The fact that the grid is placed twenty-five meters away from the soldiers, causes visibility limitations caused by snow, fog, wind and poor light conditions, at dawn or twilight. The previous SAAF technique calculates the number of error "clicks" in both azimuth and elevation. In the prior SAAF technique, the number of clicks appears on the screen, using four sets of electromechanical indicators. The soldier must turn in the correct direction the conventional SAT adjusters to the corresponding number of clicks. He or she must aim and fire the weapon again and make the corresponding additional adjustments. This repetitive process continues until the soldier obtains an indication of zero in the prior art of the SAAF. This process is time-consuming and tedious due to the normal errors incurred by the soldier in aiming each time he retires the reticular target. It is not uncommon for a soldier to need fifteen minutes to align his weapon, using all his ability, and even then he can not align it exactly. It is not only the fact of the time that is required for the alignment process using the previous SAAF technique, but it is also costly due to the large number of salvage cartridges that have to be used. The laser of a conventional SAT does not fire without igniting a salvo cartridge or using a special trigger cable for blanking. The prior SAAF technique does not have the capacity for sights, different types of handguns, or devices for night vision. Furthermore, the prior SAAF technique does not accurately verify the energy and the coding of the laser light beam, of the received laser light beam. Thus, it would be desirable to provide an improved alignment system for a short weapons SAT that eliminates the need to use a large reticular target. Such a system would preferably automatically adjust the SAT to achieve an alignment with greater speed and precision. Furthermore, preferably, such a system will only require a simple target sight that will accommodate different short weapons such as automatic weapons, special rifles for splitters and the like. These handguns not only have different cannon boxes, they are also, the laser output of their SATs has different power and codes to allow the portion of a MILES system that the person carries, to distinguish between the impacts made by different handguns.
EXHIBITION OF THE INVENTION Accordingly, the main objective of this invention is to provide an improved short weapon alignment system, for use in an integrated multiple battle laser system. This invention provides an automatic alignment system of the bore sight of a laser transmitter mounted on a short weapon. The laser transmitter has an energizable laser that emits a laser beam that is adjusted to regulate the beam of laser light in azimuth and elevation. The alignment system consists of a base unit having a first optical assembly mounted on the base unit that generates an image of a reticular target visible to the user. A weapon mount that is mounted on the base unit allows the user to adjust the azimuth and elevation of the weapon to point it to the image of the reticular target, and to hold the weapon in the position at which it is aimed. An alignment head is connectable to a laser transmitter to adjust the transmitter, and thus to orient the beam of laser light with respect to its azimuth and elevation. A second optical assembly mounted on the base unit receives the laser light beam and generates an error signal representing a displacement between a point received from the laser light beam and the image of the reticular target. A control circuit is connected to the alignment head and the second optical assembly energizes the laser and adjust the laser transmitter using the error signal to orient the laser beam in azimuth and elevation until the laser light beam is substantially aligned with the weapon's gun sight.
The preferred embodiment of our invention provides an electromechanical device that automatically aligns a laser transmitter bolted to the case of a rifle for later use by a soldier in mock war. A rectangular hollow drawer is horizontally oriented, and a hinged end cover opens upward to show an LCD screen and a keyboard of a control unit. A sliding support extends horizontally from a base unit into the drawer. The barrel of the rifle is supported by a support mounted on the base unit and the trigger guard or comb receptacle is mounted on a screw on the support. The screw has knobs to adjust the azimuth and elevation of the weapon, which allows the soldier to point to an image of a reticular target. An optical unit is mounted on a forward portion of the base unit and includes a lens and a beam splitter that is transparent to the infrared light of the laser transmitter but that reflects visible light. The illuminated reticular white is mounted inside the optical unit below the axis of the laser light beam. The beam splitter is placed in front of the lens to project the image of the reticular target through the lens to infinity. A position detector that is in the optical unit receives the laser light beam and generates an error signal representative of a displacement between a point received from the laser light beam and the image of the reticular target. The control unit has a circuit that is connected to an alignment head that mechanically engages the rear end of the laser transmitter bolted to the rifle. The circuit causes the alignment head to repeatedly fire the laser at the laser transmitter. Using the error signal, the circuit causes the alignment head to independently rotate triangular prisms in the laser transmitter to orient the laser light beam in azimuth and elevation until the laser light beam is substantially aligned with the laser viewfinder. soul of the weapon.

BEST FORMS FOR CARRYING OUT THE INVENTION Referring to Fig. 1A and IB, the preferred embodiment of our invention provides a generally designated electromechanical system 10 that automatically aligns a laser transmitter (SAT) 12 bolted to the case of a short weapon 14 as an M16 rifle to be used subsequently by a soldier in mock war. System 10 includes a rectangular hollow transit box 16 that is horizontally oriented when used. An articulated closing end cover 18 of the drawer 16 can be opened upward to expose a control unit 20 that is mounted therein. Our SAT 12 is designed to be automatically adjusted by an alignment system 10, the alignment system includes a hollow transit box 16, which has a horizontal orientation when in use. A soldier 21 points the weapon 14 inside the box 16. The soldier 21 wears a helmet 21a and a harness 21b equipped with laser detectors that detect the impact of the laser "bullet" in the war simulations. The control unit includes a box-shaped housing 22 (Fig. 2) having an LCD screen 24. The housing 22 also has a keyboard in the form of a panel with membrane switches. This switch panel surrounds the screen 24 and includes pressure operated switches 26, 28, 30, 32, 34, 36 and 38. A retractable slidable support 40 can extend horizontally from the rear end of a base unit 42 (Fig. IB) mounted towards the lower wall of the case 16. The barrel 44 of the rifle 14 rests firmly on the apex of a rigid triangular support 46 for the weapon, the base of which is mounted by bolting it to the intermediate part of the base unit 42 The trigger guard (not visible) of the rifle 14 is mounted on a screw 48 of the support 40. The screw 48 has the knobs 50 and 52 to manually adjust the azimuth and elevation, respectively, of the barrel 44 of the rifle 14. After mounting the rifle 14 in the recess 46 of the weapon and the screw 48, the soldier 21 (Fig. 1A) points to an image of a reticular target 54 (Fig. 6) projected in the line of sight of the weapon, as will be described with more detail later. The box-shaped optical unit 56 (Figs 1A and IB) is rigidly mounted to the front of the base unit 42 (Fig. IB). The optical unit 56 includes convex lenses 58 (Fig. 6) and a beam splitter 60. The beam splitter 60 is transparent to the infrared light of the laser transmitter (SAT) 12 (Fig. 1) but reflective to visible light. The reticular target 54 (Fig. 6) is mounted within the optical unit 56 below the axis of the laser light beam. The beam splitter 60 is located forward of the lens 58 at a forty-five degree angle to project the image V of the reticular white through the lens 58 to infinity. The position detector 62 in the optical unit 56 receives the beam of light laser L2 and generates an error signal representing a displacement between a place received from the laser light beam and the image of the reticular target. Then, the SAT 12 is adjusted until its laser light beam L2 hits the center of the detector 62. The control circuit inside the control unit 20 (Fig. 1) is connected to an alignment head 64 coupled in a manner Mechanical to the rear end of the laser transmitter (SAT) 12 attached by bolts to the rifle 14. The control circuit causes the alignment head 64 to repeatedly fire the laser at the laser transmitter 12. Using the error signal, the control makes the alignment head independently rotate a pair of triangular prisms 66 and 68 (Fig. 3), of the laser transmitter 12 to orient the azimuth and elevation of the laser light beam until the laser light beam is substantially aligned with the laser beam. a gun visor 44 of the weapon. System 10 can be used for the automatic alignment of the bore sight of any small arms and machine guns of the United States Army, with unlimited adaptability to new weapons. The automatic operation of the system ensures a fast (less than one minute), accurate and constant aiming of the SAT 12, after the soldier 21 makes a unique initial adjustment of the aim of the weapon 14. The use of the aiming screw 48 ensures that optical aiming and night vision devices of weapon 14 do not interfere with the aiming process of the bore sight. - The entire system 10 is contained within the transit resistant box 16, which also serves as a protector against the sun and inclement weather. System 10 does not use salvage cartridges during the alignment process and can therefore be used anywhere, such as indoors or on a table. The initial operation of the system 10 involves three simple steps that include the installation of a battery inside the housing of the control unit 22 (Fig. 1), the activation of the BIT 30 switch (Fig. 2) and the type selection. of weapon that will be aligned by pressing switch 34. Screen 24 will display text messages and instructions to the operator as to how to proceed to the next step. Once the system 10 is ready to align, the soldier 21 follows the instructions on the screen 24 to align his weapon. The normal sequence is as follows: a) The soldier attaches the alignment head 64 to the laser transmitter (SAT) 12; b) the soldier places his weapon in the aiming screw 48 and in the front rest of the weapon 46; c) The soldier points his weapon at the image of the illuminated reticular target 54 visible in the optical unit, using the azimuth adjustment knobs 50 and 52 and elevation of the aiming screw; d) The soldier presses the advance switch 28 (Fig. 2) and follows the instructions that appear on the screen 24. The type of weapon is selected by pressing the switch 34 at the appropriate time in response to a request that appears on the screen; e) The soldier backs up and presses the alignment switch 26 in the housing of the control unit 22; f) The soldier waits for the message "FINISHED ALIGNMENT" on screen 24, which will appear before one minute; and g) The soldier removes the weapon from the system following the finished alignment warning. In case the system 10 finds a problem during the alignment process, such as low power, incorrect laser code or trigger trigger problems, the system will inform the soldier that the SAT of the weapon is defective and needs to be changed. The general operation of the system 10 is illustrated in the block diagram of Fig. 7. The weapon 14 is mounted on the aiming screw 48 with the alignment head 64 attached to the SAT 12. The optical unit 56 includes the illuminated reticular white 54 to which the aim of the weapon is aimed. When the alignment switch 26 is activated (Fig. 2) the control unit 20 causes the SAT 12 to fire repetitively while controlling the SAT LED indicator 70 of fire (Fig. 3) to achieve proper operation. The optical unit 20 captures the laser location by sensor and sends that data to the control unit 20, which in turn determines the amount of correction needed. The control unit 20 in turn causes the alignment head 64 to make the necessary adjustments to the SAT 12. The process continues in real time until the SAT 12 is precisely aligned. The control unit 20, together with the optical unit 56, also checks the laser energy levels, the laser codes and that the alignment optics of the SAT are functioning in the desired manner. The five major subsets of system 10 will be discussed in more detail later in this document. The optical unit 56 (Fig. IB) is the assembly projecting the illuminated reticular target 54 to the soldier 21 during the aiming adjustment of the bore sight and sensor senses the location of the laser light beam of the weapon, in relation to the reticle . The illuminated reticle 54 helps the soldier 21 to see through the anima under conditions of reduced illumination as in the twilight or dawn. Fig. 6 illustrates the operation of the main components of the optical unit 56. The large convex lens 58 performs the function of collimating and focusing the laser light beam at a point of the longitudinal position sensing sensor 62, which is located at the focal point of the lens 58. When the angle of incidence to the lens 58 of the laser light beam is not perpendicular (misaligned) the position of the point in the detector 62 is displaced. The detector 62 passively quantifies the amount of displacement and sends the error to the control unit 20. The detector is preferably a solid state device, such as a quad detector or it can be a linear detector with analog output. Within the path of the laser beam is the beam splitter 60, which is reflective to visible light while allowing the infrared light of the laser to pass therethrough. The beam splitter 60 is positioned at a forty-five degree angle to project an image of the reticular target 54 by means of the same lens as the input laser. The targeted target 54 is illuminated by a visible light source, such as an LED 72, and is positioned so that the projected image is on the same optical axis as the zero point of the detector 62 to detect the position. No adjustments are required in the field of the optical unit 56 and the system 10 does not need to contain electronic parts apart from the detector 62 and the LED light source 72 to illuminate the reticular target 54. To the base unit 42 between the tip of the barrel 44 of the weapon and the optical unit 56, an L-shaped protection barrier 74 is secured rigidly with bolts (Fig. 1). Its purpose is to prevent the soldier inadvertently knocking the lens 58 of the optical unit with the barrel 44 when mounting the rifle 14 on the rest of the weapon 46 and on the screw 48. The barrier has a hole that goes through it, covered by a maya of metal 76 to allow the laser light beam, which can be eight millimeters wide, to pass through it to the optical unit 56. It is not desirable to cover the hole with glass or other solid transparent material, since this will be It can dirty, dim the laser beam or create deflection in the laser beam, causing a lack of precision. The alignment head 64 (Figs 5A and 5B) is an electromechanical device that is attached to the SAT 12 by means of a cable 65 (Fig. 1A) and automatically adjusts the position of the SAT laser, as indicated by the control unit 20. The alignment head 64 contains an inductance coil 78 (Fig. 5A), which is used to trigger the LAS laser, and if required by means of the switch 30 (Fig. 2) it transfers to the SAT an identification of test of the person making the shot (PID). The head 64 also has a detector 80 that monitors the fire LED 70 of the SAT to determine its operating status. Two miniature gear reduction motors 82 and 84 (Fig. 5B) and a gear train of related displacement 86 and 87 are used within the alignment head 64 to rotate the non-slip couplings (not visible) in a pair of shafts geared 188 and 120. The couplings are fitted on the ends of adjustment axes 106 and 108 of the SAT. The control unit 20 drives and controls the motors of the alignment head 82 and 84 during the process of alignment of the barrel axis while the optical unit 56 detects the laser of the SAT and provides real-time feedback to the control unit 20. The laser transmitter (SAT) 12 (Fig. 3) includes a housing assembly 88 with a removable cover 90 and forming the rear part thereof. A laser diode assembly 92 is mounted within the housing assembly 88 and energized by a power circuit in a controller card 94, also mounted within the housing assembly 88. The power circuit is energized to energize the laser diode 92 by means of an inductive switch 96 mounted within the assembly 90 of the back cover. The inductive switch is activated by energizing the inductive coil 78 (Fig. 5A), which is placed above the top of the housing assembly unit 88 (Fig. 3) aligned with the inductive switch 96. The front end of the housing assembly unit 88 (Fig. 3) of the SAT coincides with the holes 98 and 100. In the hole 100 an optical or audio sensor is located to detect the fire of a salvo cartridge, and is connected to the circuit of the controller card 94. In the other window 98, a transparent window 102 is mounted to allow passage of the light beam of the laser diode assembly 92. Behind the window 102 there is an optical sleeve 104. The optical triangular prisms 66 and 68 are supported behind the window 102 so that they can rotate independently by the drive shafts 106 and 108, respectively. The forward ends of these shafts have gears 106a and 108a for moving the toothed peripheral portions of the optical triangular prisms 66 and 68, respectively. The drive shafts 106 and 108 are hinged in bearings such as 110 and 112. The rear ends of the drive shafts 106 and 108 extend through holes (not visible) in the rear cover assembly assembly 90, and it is sealed with O-rings 114 and 116. These ends of the shaft are protected by means of a rigid projection 90a extending perpendicularly from the assembly 90 of the rear cover. When the alignment head 64 (Figs 5A and 5B) is coupled to the rear cover assembly 90 of the laser transmitter (SAT) 12, the non-slidable couplings (not visible) of the geared shafts 118 and 120 (Fig. 5B) of the alignment head 64 are connected to the ends of the shafts 106 and 108 to provide drive connections to the motors 82 and 84. Fig. 4 illustrates diagrammatically the orientation of the light of the laser light beam B by independent rotation of the optical triangular prisms 66 and 68 by means of the motors 82 and 84 of the alignment head 64. The optical triangular prisms they can be used as orientation elements of the laser light beam in the optical systems. The minimum deviation or deflection that a beam or beam undergoes when passing through a thin triangular prism of the vertex angle? "Is approximately obtained by? D - (n - 1)?" 9 where n is the reflection index. The "power" (?) Of a prism is measured in diopters of the prism, defining the diopter of the prism as a deflection of 1 cm at a distance of one meter from the prism. In this way ? = 100 tan (? D). By combining two triangular prisms with equal power (equal deviation) in close contact, rotating each one independently on an axis almost parallel to the perpendiculars of their adjacent faces, it is possible to orient in any direction a laser beam B that passes through the combination , inside a narrow cone, by the trajectory of the deflected beam of light.
The angular radius of this cone is approximately? D. The vertex angle is controlled with very little tolerance in the manufacturing process of the triangular prisms. Deviation angles (wavelength functions) are nominally specified as a result of the melt-to-fusion tolerance index. The deflection angles are specified under the assumption that the input light beam is perpendicular to the perpendicular phase. Of course, the deviation will be different with other entry angles. The equation to determine the angle of deviation for the same input direction, but with other wavelengths is:? D = arcsen (n sin? ") -?" < where? d is the angle of deviation,? "is the angle of the triangular prism and?" - is the index perpendicular to the appropriate wavelength. Optical triangular prisms are available in various materials, such as cast synthetic silicon, as well as in different shapes and sizes. The control unit 20 (Fig. 1A) provides an LCD screen 24 (Fig. 2) easy to use for the user, and controls that continuously inform the user about the status of his weapon, while providing instructions progressively throughout the alignment process. The control unit 20 is mounted within the cover of the transit box 18. The LCD screen 24 can be easily read when the cover 18 is in the open and raised position. As described above, the control unit 20 provides all the controls and supervises all the activities of the optical and head alignment units 56 and 64. The front panel with the membrane switches and the integral LCD screen 4X20 24 provides the interface with the user. The following describes the functions of the switches: a) ALIGNMENT "ALIGN" (26) - This switch is activated by the soldier after he has aimed the gun sight at the reticular target of the optical units. b) CONTINUE "PROCEED" (28) - This switch is activated by the soldier at any time, when he wants to go to the next alignment step, or to recognize a message that appears on the screen. c) "BIT" (30) This switch is activated during the initial preparation of the system to verify that it is ready. d) PID RECOGNITION "PID LEABN" (32) - This switch is used to transfer the PID test of the system to the SAT 12, in order to verify that the transfer function works. The use of this switch is optional and is only used if there is any doubt as to whether the SAT of the weapon entered can accept other PIDs. e) SELECT WEAPON SELECT ARM (34) - This switch is used together with the two switches with arrows 36 and 38 to select the type of weapon that will be aligned (M16A2, M2, M240, etc.). This selection determines the levels of energy and the codes that the system will verify. f) ARROWS (36 and 38) - These switches are used to select different types of weapons. The aiming screw 48 (Fig. IB) is a stable mechanism that is used to hold and aim the weapon 14 that is being aligned. It allows the soldier to align the barrel using any of the means to aim with which this method counts, and eliminates the possibility of the weapon deviating from the point at which it is aimed. The screw 48 is attached to the sliding support 40, which is retracted into the base unit 42 of the transit box to conform to the various weapon lengths. The aiming screw 48 has adjustment knobs 50 and 52 for both azimuth and elevation adjustment, which allow the soldier to accurately aim the sight of his weapon at the image of the reticular target 54. The front part of the weapon barrel 44 it rests on the support 46 of the weapon, located inside the transit box 16 in the base unit 42 of the transit box. The main components of the system 10 are integrated into the transit box 16, which provides a safe and durable means to carry them during transport and operation. Box 16 also provides protection from the sun and inclement weather, making it possible to carry out the alignment process in almost any environment. The base unit 42 is mounted on the bottom wall of the box. The optical unit 56, the support for the weapon 46, and the sliding support with aiming screw 40, are attached to the battery of the base unit (not visible) to provide power to the system, they are contained within the base unit 42. The control unit 20 is attached to the inner part of the front cover 18A. Fig. 8 is a block diagram of the energy of the optical output and of the code accuracy check circuit of the control unit 20. A coding circuit 122 is connected to the microcomputer (not shown) by means of a serial data bus 124. The optical bit amplifier 126 in the path of the laser light beam sends signals to the electronic coding parts.
Although we have described a preferred embodiment of our laser alignment system for handguns with automatic identification of the user, it will be apparent to those skilled in the art that our invention can be modified, both with respect to its disposition, and to its details, accordingly, the protection provided to our invention may only be limited in accordance with the following claims.

Abstract An electromechanical device that automatically aligns a laser transmitter bolted to the case of a rifle to be later used by a soldier in mock war. A rectangular hollow drawer is horizontally oriented, and a hinged end cover opens upward to show an LCD screen and a keyboard of a control unit. A sliding support extends horizontally from a base unit into the drawer. The barrel of the rifle is supported by a support mounted on the base unit and the trigger guard or comb receptacle is mounted on a screw on the support. The screw has knobs to adjust the azimuth and elevation of the weapon, which allows the soldier to point to an image of a reticular target. An optical unit is mounted on a forward portion of the base unit and includes a lens and a beam splitter that is transparent to the infrared light of the laser transmitter but that reflects visible light. The illuminated reticular white is mounted inside the optical unit below the axis of the laser light beam. The beam splitter is placed in front of the lens and has an angle of forty-five degrees to project the image of the reticular white through the lens to infinity. A position detector that is in the optical unit receives the laser light beam and generates an error signal representative of a displacement between a point received from the laser light beam and the image of the reticular target. The control unit has a circuit that is connected to an alignment head that mechanically engages the rear end of the laser transmitter bolted to the rifle. The circuit causes the alignment head to repeatedly fire the laser at the laser transmitter. Using the error signal, the circuit causes the alignment head to independently rotate triangular prisms in the laser transmitter to orient the laser light beam in azimuth and elevation until the laser light beam is substantially aligned with the laser viewfinder. soul of the weapon.
