Description

    TECHNICAL AREA
  • The present invention relates to a Feuerleitvisier for a handgun according to the preamble of claim 1. It further relates to a handgun with such Feuerleitvisier and a method for aligning such a handgun.
  • STATE OF THE ART
  • A generic Feuerleitvisier with the features of the preamble of claim 1 is known from US 4 016 652 A known.
  • The US 2007/0056203 A1 shows and describes a sighting system for a firearm, which has a range finder, an inclinometer and a control computer and an indicator lamp. The indicator lamp is disposed in a sighting slot provided on one side of the visor. The shooter first determines the distance to the target by means of the distance measuring device by aiming the target directly. This measured distance is stored in the control computer, whereupon it calculates the ballistic trajectory of the previously selected ammunition and determines the required inclination angle of the firearm. The shooter sights the target and then aligns the tilt of the firearm until the indicator light indicates by a green signal that it has reached the correct angle of inclination. If the incline is too low, the indicator light flashes red.
  • From the EP 0 785 406 A2 a grenade launcher attachable to a handgun is provided with a laser range finder and a digital compass. The laser rangefinder is provided with an LED display device by means of which the shooter can instruct the target.
  • The shooter is completely dependent on the electronic Zieleinweisungsvorrichtung in this known device. In case of a possible failure of the electronics any redundant Zieleinweisungsmöglichkeit is missing.
  • The US Pat. No. 6,499,382 B1 shows and describes an electronic sighting device as a target system for a heavy weapon, which is pivotally and tiltably mounted on a tripod or other base device. This target system is connected to the weapon such that the target system can rotate with the weapon in the azimuth direction and pivot in the elevation direction. The target system has a camera and a screen over which the shooter can instruct the target. This known device is too large and too heavy for use on a handgun.
  • From the US 2005/0268521 A1 For example, an electronic sighting device for a firearm is known, which is equipped with a tilt sensor, an accelerometer and a gyro. Also, this sighting device is large and heavy and less suitable for a handgun. In addition, there is no redundancy available in case of failure of this electronic sighting device.
  • Previously customary visor displays often use a superimposed in the optical beam marking the breakpoint, which has the disadvantage that the opening angle of the sighting optics must cover the maximum elevation angle. For distant targets, however, this angle quickly exceeds the usual visor aperture angles, as there are elevations of up to 45 °. Especially at these high elevations, a distant target (for example 450 meters away) is fought, for the measurement of which one would need a magnifying visor with a small opening angle on the other hand.
  • Another well-known solution for the aforementioned target antagonism is the "tilting" of the beam path via a motor-driven mirror or a prism within the sighting optics. This solves the problem of contradicting large viewing angles and sufficient magnification. However, such systems have a relatively large inertia of the entire sighting system, which by the motor pivoting action of the mirror is caused. In addition, the field of view of the shooter is limited to the small opening angle of the visor.
  • In all these known electronic visors, the shooter must additionally carry a classic Leiterstaier as fallback solution, so that he can still use the weapon even in case of failure of the electronic sighting device.
  • The object of the present invention is to provide a generic Feuerleitvisier that allows a quick and accurate elevation control for the shooter by intuitive representations, without causing a significantly increased weight must be carried on a firearm. In addition, the Feuerleitvisier should have redundancy, if the auxiliary electronic displays fail. Another object is to provide a handgun with such a Feuerleitvisier and a method for aligning such a handgun.
  • PRESENTATION OF THE INVENTION
  • The directed to the Feuerleitvisier solution of the problem is achieved by the Feuerleitvisier with the features of claim 1.
  • This Feuerleitvisier for a handgun, in particular for a grenade gun, is provided with a visor housing, a visor, a sighting ladder, the two visor ladder having a plurality of visor forming visor rungs and is characterized by a distance measuring device, at least one inertial sensor and / or a magnetic field sensor and / or another direction-preserving sensor unit, a control computer and a display direction for displaying an optimal alignment of the barrel axis of the handgun determined by the control computer. The display device for indicating the optimum elevation of the barrel axis of the handgun has at least one row of electro-optical elevation signal elements extending along at least a portion of a sighting guide beam and the control computer is designed to provide a control device for the To apply electro-elevation signal elements with an elevation indication signal.
  • ADVANTAGES
  • This Feuerleitvisier invention integrates an electro-optical display system in a classic Leitervisier that signals the shooter the optimal breakpoint and allows a precise fine alignment by a non-linear optical bar display. The distance data are measured by a distance measuring device, for example a laser distance meter, and the position of the handgun is determined via at least one inertial sensor. The invention thus consists in the integration of a display device for displaying a determined by the control computer optimal alignment of the barrel axis of the handgun in a standard Leiteausier. The display device is controlled by a control computer, which knows about connected sensors the current position of the handgun to the pitch angle, the roll angle and the azimuth angle. Furthermore, the distance to the target is determined by a distance measurement with the integrated distance measuring device and the direction of the target is determined by means of the magnetic field sensor or another direction-preserving sensor unit (for example by means of gyroscopes). The control computer is provided or connected to an electronic storage device in which a table of the Feuerleitvisiers is stored with stored Geschosparametern. After measuring the target position, the control computer calculates the optimum ballistic trajectory of the projectile to be fired by the handgun, for example a grenade, from these projectile parameters and the recorded measurement data, and displays the target elevation to the shooter on the display device. This inventive combination of classical mechanical ladder sight and electronic Feuerleitvisier can be referred to as "active Leitervisier". This Feuerleitvisier invention represents an ideal hybridization of the classic Leiteaus with the electronic display device mounted thereon. The shooter is offered by a sighting that it due to the electronic Display device allows fast and accurate make a target instruction of the weapon, on the other hand, but also in case of failure of the electronic display device or other electronic elements classic targeting of a target using the mechanical Leitervisiers allows without an additional Leiteausier carried and in case of failure of the electronics only the handgun must be attached.
  • It is particularly advantageous if the electro-optical elevation signal elements are formed by LEDs.
  • Preferably, the electro-optical elevation signal elements can each assume different, preferably at least two, display states. If the signal elements are formed, for example, by LEDs, then they can assume the display states OFF, ON and, when switched on, also different colors. For example, if the display elements are not formed as discrete LEDs but are formed by a screen display, different shapes of each display element may be provided as an alternative to different colors.
  • It is also advantageous if the display device for indicating the optimal azimuth alignment of the barrel axis of the handgun at least one, preferably in the region of the sighting grain, is arranged and has an electro-optical azimuth signal element. This additional measure makes it possible to optimally set not only the elevation angle, but also to provide the shooter with assistance in the horizontal pivoting of the weapon. It is advantageous if the at least one electro-optical azimuth signal element can assume different, preferably at least two, display states. Again, the same display conditions can be provided as in the elevation display.
  • It is particularly advantageous if the Feuerleitvisier additionally has an air temperature sensor, an air pressure sensor and / or an air humidity sensor. This allows the calculations of the optimal Trajectory of the projectile and thus perform the calculation of the optimal elevation even more precise.
  • It is also advantageous if a distance indicator for displaying the distance measured by the distance measuring device is provided for the shooter.
  • The directed to the handgun part of the task is solved by a handgun, which is provided with a Feuerleitvisier according to the invention. This Feuerleitvisier can be attached, for example by means of a Picatinny rail on the handgun, for example, on the grenade gun. Such a Picatinny rail is a standardized serrated rail for quick assembly of accessories to handguns according to the international standard MIL-STD 1913.
  • The directed to the method part of the object is achieved according to independent method claim 9 by a method for aligning a handgun according to the invention to a target with the steps
  1. a) direct sighting of the target by means of the fire-control sight;
  2. b) determining the distance to the destination by means of the distance measuring device;
  3. c) calculating the trajectory and the elevation angle by means of the control computer;
  4. d) displaying the calculated elevation angle and the deviation of the current elevation angle from the calculated elevation angle by means of the display device, wherein the display of the deviation of the current elevation angle from the calculated elevation angle by means of at least one row of electro-optical elevation signal elements extending along at least a portion of a visor ladder,
    • that the calculated elevation angle by a first elevation signal element in a first color and / or Symbol representation is displayed at the level of the visor, with which the target must be targeted via the sighting grain,
    • one or more of the lower elevation signal elements located below the first elevation signal element are displayed in a second color and / or symbol representation if the current elevation angle is less than the calculated elevation angle,
    • that one or more of the upper elevation signal elements located above the first elevation signal element are displayed in the second color and / or symbol representation when the current elevation angle is greater than the calculated elevation angle and
    • that the first elevation signal element changes its color and / or symbol representation when the current elevation angle is equal to the calculated elevation angle.
  • In this method, the shooter who sighted by the visor on the Visierholmholm over the visor target, displayed by means of, for example, on the visor or headlamp display the calculated elevation angle and the deviation of the current elevation angle of the calculated elevation angle, so that the shooter at classical optical sighting of the target receives additional information about the display device by means of which he can quickly and precisely align the handgun so that the bullet on his ballistic trajectory reliably hits the target. By the term symbol representation is meant, for example, a shape or a brightness state of a signal element. Thus, a change of the symbol representation, for example, a change in shape of the display (eg change between circle and triangle) or a change in brightness of the display (eg, a continuous display or a flashing with different frequencies). With the inventive method, a simple, fast and secure alignment of the barrel axis of the handgun is achieved. The procedure is designed so that a shooter without much training can operate the weapon intuitively and to him by the special design of the so-called active Leiters with the elevation signal elements the correct operation of Feuerleitvisiers invention quasi imposed.
  • An advantageous further development of this method is characterized in that the display of the deviation of the current elevation angle from the calculated elevation angle in step d) takes place by means of at least one row of LEDs extending along at least one section of a sighting guide beam.
  • Preferably, in step c) an additional calculation of the azimuth angle to the target by means of the control computer and in step d), the deviation of the current azimuth angle from the calculated azimuth angle is additionally displayed by means of the display device. This advantageous functionality, which is based on the measurements of the at least one inertial sensor and / or the at least one magnetic field sensor, ensures that the shooter not only receives an aid for the elevation alignment of the weapon when aiming the target, but also for the azimuth alignment of the weapon, and thus a safe targeting is also achieved in the horizontal direction.
  • It is particularly advantageous if the display of the deviation of the current elevation angle from the calculated elevation angle in step d) by means of at least one along at least a portion of a Visierleiterholms extending series of electro-optical elevation signal elements, preferably LEDs, such takes place that the calculated elevation angle is displayed by a first elevation signal element in a first color and / or symbol representation at the level of the sight, with which the target must be targeted via the sighting grain that one or more of the arranged below the first elevation signal element lower elevation signal elements are displayed in a second color and / or symbol representation when the current elevation angle is less than the calculated elevation angle, that one or more of the elevation signal elements located above the elevation upper signal elements in the second color and / or symbol representation are displayed when the current elevation angle is greater than the calculated elevation angle and that the first elevation signal element changes color and / or symbol representation when the current elevation angle equals the calculated elevation angle.
  • Through these steps, the shooter is guided intuitively to the correct azimuth alignment of the weapon. By combining this guided azimuth orientation with the guided elevation alignment, fast and accurate targeting can also be accomplished by less skilled shooters.
  • The combination according to the invention of a classical conductor sight with a display device, for example comprising LEDs, which are arranged, for example, in the form of a respective luminous line on the bars of the sighting conductors on the left and right, creates a combined Feuerleitvisier, both in the classical manner as optical Leitervisier and in electro-optically supportive way can be used. For example, LEDs with two different color elements are used in the luminous lines of the display device, with which three colors (color 1, color 2 and the mixed color 1 + 2) can be displayed. For the sake of simplicity, the colors red, green and yellow are suggested here, but also any other colors and color combinations are possible. This simple and meaningful color coding contributes to the fact that the function of the fire control is self-explanatory and the shooter can perform the alignment steps of the inventive method almost intuitively correct.

The Feuerleitvisier 1 is equipped with a distance measuring device 2, which has a laser rangefinder 20. Furthermore, at least one inertial sensor 3 and at least one magnetic field sensor 6 or another direction-maintaining device (for example by means of gyros) are provided. Finally, an air temperature sensor 70, an air pressure sensor 71, and an air humidity sensor 72 are provided. The sensors 3, 6, 70, 71, 72 are connected to a control computer 4, which is likewise provided in the visor housing 10. The distance measuring device 2 is also connected to the control computer 4. A current storage device 40 supplies the control computer 4 as well as the sensors and the distance measuring device as well as the display device 5, which will be described further below, with electrical energy.
  • The display device 5, which is also connected to the control computer 4, comprises a plurality of electro-optical signal elements, which can be acted upon by the control computer 4 with an electrical signal to illuminate in one or different colors.
  • In the Fig. 2A A sighting conductor 14 shown in a view visible to the shooter is constructed in a classical manner and has a left sighting rail 15, a right sighting rail 16 and a plurality of sighting rails 18a, 18a ', 18b, 18b', 18c, 18c ', 18d, 18d'. , 18e, 18e ', of which in each case a left and a right visor rung between them define a gap which forms a respective visor 17a, 17b, 17c, 17d, 17e. This structure essentially corresponds to a classic mechanical sighting ladder.
  • In the sighting guide 14 of the invention, a series of electro-optical elevation signal elements 51, 53 is provided on each of the two sighting guide rails 15, 16, each being formed of a series of light-emitting diodes (LEDs). These LEDs are, as described below, controlled by the control computer 4 so that they can be turned off or turned on, wherein at least a portion of the LEDs in the on state can shine in different colors.
  • For this purpose, the control computer 4 acts on a (not shown) control device for the electro-optical elevation signal elements 51, 53 with an elevation indication signal.
  • Furthermore, in the view of Fig. 2A to recognize that the back of the visor housing 10 is provided with an electro-optical display device 22 for displaying the distance measured by the distance measuring device 2.
  • Fig. 2B shows the visible to the shooters view of the sighting 12, which is provided on a fold-out visor holder 11. Below this sighting grain 12, an electro-optical azimuth signal element 54 is provided, which also belongs to the display device 5 and is formed by an LED. To the left and right of the azimuth signal element 54 are provided a left azimuth correction signal element 54 'and a right azimuth correction signal element 54 "which are also formed by an LED and belong to the display device 5. The two azimuth correction signal elements 54 ', 54 "can, as in Fig. 2B shown formed by separately mounted on the visor carrier 11 signal elements. The task of these two azimuth correction signal elements can, however, also be assumed by corresponding signal elements on the left or right visor ladder stile 15, 16 which lie in the sighting line plane to the left and to the right of the azimuth signal element 54.
  • Fig. 3 shows a block diagram of the components of the Feuerleitvisiers invention. The control computer 4 comprises a computer unit 42 having a volatile memory provided therein and a flash memory 44 connected to the computer unit 42. The power supply unit 40 is connected to a battery pack 41 and has a voltage regulator with power saving function and automatic shutdown of the connected devices. Connected to the control computer 4 are a plurality of sensors, namely three acceleration sensors 30, 31, 32, three rotation rate sensors 33, 34, 35, three magnetic field sensors 60, 61, 62 which together form a magnetic field sensor 6, the air temperature sensor 70, the air pressure sensor 71 and the humidity sensor 72 provided in the laser rangefinder 20 of the distance measuring device 2 laser distance sensor 21 and a brightness sensor 73. Furthermore, the control computer 4 is connected to a pilot laser 19 usually provided on the fire guide, which is designed to emit a laser beam at a minimum distance and (in the correctly adjusted state of the fire guide 1) parallel to the beam direction of the laser of the laser rangefinder 20 and also parallel to the axis X. The pilot laser 19 and the laser rangefinder 20 are harmonized by the manufacturer with respect to their beam paths.
  • Furthermore, the control computer 4 is connected to input and output devices. Thus, for example, an on / off switch 45, a button 46 for starting the removal measurement, a multifunction control switch 47 and a data transmission interface 48 are provided and connected to the control computer 4.
  • Finally, the control computer 4 is still connected to the display device 5, which, as already described, the two rows of electro-optical elevation signal elements 51, 53 on the respective visor beam 15, 16, the electro-optical signal elements on the visor carrier 11 (azimuth signal element 54 and Azimuth correction signal elements 54 ', 54 ") and the display device 22 has as an additional display.
  • Fig. 4 and the enlarged detail of the Fig. 4A schematically show the orientation of in Fig. 1 shown handgun W with the barrel axis X, which is inclined at an elevation angle α to the horizontal H such that the shot of the grenade gun W 'on the handgun projectile of the ballistic web B following the target Z strikes. In this case, the sight line V from the target Z extends over the visor com 12 to the uppermost sight 17e of the visor 14 provided for a plurality of visors arranged one above the other.
  • Fig. 5 shows in a flow chart the process of targeting, the weapon alignment and the combat of the target Z. In the left vertical block of Fig. 5 the individual process steps are listed and in the right vertical block of the Fig. 5 are assigned to the individual process steps parent step group names. The method according to the invention for aligning a handgun with a target comprises the upper three method step groups.
  • The process of using the fire guide with active optoelectronic guide sight, which is in Fig. 5 is divided into four phases after switching on:
    • Target detection by the weapon sight (from the shooter)
    • internal data processing and trajectory calculation (automatic)
    • Aligning the weapon to the optimum alignment angle in elevation and azimuth (by the shooter based on the indication on the guide sight and on the visor carrier)
    • Trigger the shot and reload if necessary for another shot at the same target.
  • Fig. 6 shows the orientation of the weapon W in the step of Zielanmessung, ie in the step in which the weapon W is directed to the target Z and wherein the preferably operating in a poorly detectable infrared beam range laser beam L of the laser rangefinder 20 points to the target.
  • To adjust the laser rangefinder 20 on the weapon, so to harmonize the weapon sighting optics with the laser optics, the working in the visible spectrum of the light pilot laser 19 is first turned on, directed to a 20 meters to 30 meters away object and the installation position of the laser rangefinder 20 with example adjusted two adjustment screws so that the spot of the pilot laser 19 is aimed centrally by the weapon sight. This adjustment step takes place at least immediately after the first installation of Feuerleitvisiers on the weapon, but can also be performed if necessary before each use of the weapon.
  • For targeting the shooter uses the familiar sight of the weapon. He aligns the weapon classically on the target and presses the button 46 to the target detection by the Feuerleitvisier. This button 46 is usually connected by a cable to the Feuerleitvisier and attached to a position suitable for the shooter on the weapon.
  • With the laser rangefinder 20, only the direct distance to the target Z is determined. The distance is numerically in Fig. 5 displayed as an additional display display of the display device 22 is displayed. The inertial sensors (acceleration sensors 30, 31, 32 and yaw rate sensors 33, 34, 35) and the magnetic field sensors 60, 61, 62 measure the orientation of the weapon W to the target. Any height differences between the shooter's location and the target Z are also recorded. In parallel, the current values for temperature, air pressure and humidity are read out of the sensors 70, 71, 72. From the computer device 42 of the control computer 4, the optimum shooting angle (elevation angle) is then calculated from these variables, the stored projectile parameters which are read from the flash memory 44. The azimuth is primarily taken from the measurement.
  • The Fig. 7 Figure 11 shows the elevation display of the elevation electro-optic signal elements on the ladder sight in direct aiming at the target Fig. 6 after the distance to the target has been measured and the control computer 4 has calculated the required elevation angle. The left and right elevation signal elements 55, 55 ', which are both at the level of the sighting 17d, through which the line of sight V is in correct elevation alignment of the weapon W, light up red, since the weapon W is not aligned correctly , The below these two lying elevation signal elements 56, 56 'light up in yellow and the elevation signal elements arranged above are switched off. This ad, which also once again in Fig. 10B shows the shooter that he keeps the weapon too low.
  • In Fig. 8 is schematically shown the orientation of the weapon W at the correct elevation angle α. The projectile fired by the grenade gun W 'of the weapon W at this elevation angle α follows the ballistic trajectory B into the target Z.
  • The Fig. 9 shows the image of the display device 5 in the in Fig. 8 illustrated case of the correct elevation alignment of the weapon W, now the elevation signal elements 55 and 55 'no longer red, but green light up. Only one left and one right electro-optical elevation signal element 56A, 56A 'below the green illuminating elevation signal elements 55, 55' and one left and one right elevational signal element 57A, 57A 'arranged above it illuminate yellow. This picture, which is also in Fig. 10D is displayed, indicates to the shooter that he has aligned the weapon W in the optimal elevation.
  • The 10A to 10D show different signal representations, the display device 5 indicates the shooter at different elevation orientation of the weapon W. By means of this light bar display, the shooter does not have to read off the desired overstep position from the rungs of the sight guide, but is signaled to him by the light bar display. In the case of a weapon that is much too low, the shooter gets the in Fig. 10A shown image, in which about the lower two thirds of each provided on the Visierleitersprossen elevation signal elements 51, 53 light yellow, while about the upper third does not light up.
  • If the shooter approaches the elevation of weapon W to the correctly calculated elevation angle α, he sees this in Fig. 10B illustrated picture. The desired over-elevation position of the weapon W, ie the desired elevation angle, is signaled to it by a right and left elevation signal element 55, 55 'emitting red in the desired height, for example red. A light bar represented in a different color, for example in yellow, has a length proportional to the deviation from the ideal angle. The function with which the deviation angle in the elevation in the light bar length, ie in the number of in this other color (yellow) illuminated elevation signal elements, is transmitted, is non-linear and spreads the area around the optimum value, in order to ensure the best possible hit probability.
  • In the picture of the Fig. 10B the optimum shooting angle is signaled to the shooter by the red flashing elevation signal elements 55, 55 'at the level of each sighting 17d, with which he must bring the sighting grain 12 and the target Z in line for an optimal shot. Furthermore, the shooter is shown in the display of the display device 22, the distance to the target. Once the shooter straightens the weapon, the display of the display 22 changes to the distance at which a shot fired at this elevation angle would hit the target away.
  • While in Fig. 10A the visor is shown, which sees the shooter, if he keeps the weapon in the horizontal measuring orientation not yet employed under an elevation angle and he gets displayed with the yellow light bars that the weapon is kept too low, is in Figure 10B shown the representation in which the shooter keeps the weapon only slightly too low. The length of the respective yellow light bar is non-linearly proportional to the vertical misalignment and is spread near the optimum elevation angle, so that the indication of the transition of the in Fig. 10A shown illustration for in Fig. 10B shown representation becomes more sensitive.
  • Similar to the illustration in Fig. 10B is in Fig. 10C the display of elevation signal elements presented to the shooter when he holds the weapon too high. In this case, above the elevation signal elements 55, 55 'which indicate the optimum elevation angle, in each case a short yellow bar is formed by the elevation signal elements 57, 57' located above it.
  • The Figure 10D shows the image providing the shooter with optimally aligned elevation of the weapon W. Here, the elevation signal elements 55, 55 'indicating the optimum elevation angle switch from the first color (for example red) to a second color (for example green) and respectively an elevation signal element Above and below yellow light up, which serves the better visualization of the correct elevation angle, but does not necessarily have to be provided.
  • Similarly, the shooter will see the correct azimuth alignment of the weapon, as in Figs. 11A to 11E is shown. Since the shooter can usually aim the target directly through the sight through the sighting 12, this azimuth support is not mandatory. In the 11A to 11 E shown visualization is similar to the in 10A to 10D illustrated elevation alignment of the weapon. The central azimuth signal element 54 lights up red as long as no optimal horizontal alignment has yet occurred. The right-side azimuth correction signal element 54 "lights up yellow if the weapon is held too far to the right ( Fig. 11A ). The left azimuth correction signal element 54 'lights yellow when the weapon is too far to the left ( Fig. 11B ). With only slight lateral misalignment of the weapon illuminated in addition to the yellow in yellow corresponding correction signal element (54 'or 54 "), the mean azimuth signal element already green, as in Fig. 11C is shown for a slightly too far-oriented weapon.
  • If the horizontal alignment is correct, the center azimuth signal element 54 glows green and the two lateral azimuth correction signal elements 54 ', 54 "light yellow (FIG. Fig. 11D ).
  • If both the elevation and the azimuth are correct, all three signal elements, ie the azimuth signal element 54, the left azimuth correction signal element 54 'and the right azimuth correction signal element 54 "shine green ( Fig. 11E ).
  • Once the weapon W has been optimally aligned, the shooter triggers the shot. He can then reload the weapon if necessary and combat the still stored target again and possibly correct the target position slightly by deliberately shooting a predetermined distance further or less, taking into account the distance display on the display of the display device 22.
  • The in Fig. 3 shown schematically and already mentioned multi-function control switch 47 can serve to switch different functions, for example:
    • a manual distance correction of the target distance displayed on the display of the display device 22, for example for correction for further shots,
    • switching between different stored parameter sets for different types of ammunition,
    • switching the language and the units used (for example meters or feet),
    • an activation of the pilot laser,
    • a readjustment of the display brightness,
    • an indication of maintenance information.
  • The brightness of the electro-optical signal elements and the backlight for the display of the display device 22 automatically adjusts depending on the external brightness. For this purpose, the signal of the brightness sensor 73 is evaluated. In addition, for example via the multifunction control switch 47, a residual light amplifier mode can be selected in which the brightness of the backlight of the display of the display device 22 and also the brightness of the electro-optical signal elements is minimized so that it is almost invisible to the naked eye, but still recognizable by means of the residual light amplifier.
  • The Feuerleitvisier 1 according to the invention also has a power saving function and an automatic shutdown in response to a predetermined time limit and by a movement of the Feuerleitvisiers or the weapon equipped with it.
  • Via the data transfer interface 48 new ammunition parameters can be loaded into the corresponding memory (for example the flash memory 44) of the fire-control sight 1. Furthermore, over the Data transfer interface 48 Status information such as error codes can be read out and internal configuration data can be changed.
  • Reference signs in the claims, the description and the drawings are only for the better understanding of the invention and are not intended to limit the scope.
