CROSS REFERENCE OF RELATED APPLICATION
[0001] This is a divisional application of U.S. patent application
Ser. No. 12/911,525, filed Oct. 25, 2010, which claims priority
under 35 U.S.C. 119(a-d) to CN 201010511597.8, filed Oct. 19,
2010.
BACKGROUND
[0002] 1. Field of the Invention
[0003] The present invention relates to the field of firearm
sights, more particularly, to a touch display screen used for
adjusting and determining the reticle of an electronic firearm
sight.
[0004] 2. Brief Description of Related Arts
[0005] Over times, people invented a variety of instruments and
devices to help shooters to aim at a target. In general, the
conventional sighting devices used in firearms can be categorized
into telescopic sight, reflex sight and other sights based upon
different principles.
[0006] To achieve the goal of aiming at a potential target
accurately, rapidly and conveniently, a reticle is a very important
factor to locate the target. Other auxiliary aides, such as
measuring the range, can be also used. However, the design and
usage of current reticles have many disadvantages. The existing
firearm sight, including the two types described above and an
electronic sight uses two devices to adjust the reticle. One is
controlling the reticle to move vertically so as to make it
superimposed on the bullet's impact point, namely up and down; the
other is controlling the reticle to move horizontally, namely left
or right. However, these adjusting methods have the following
shortcomings:
[0007] On the one hand, the existing sight, either mechanically or
electronically, all set two buttons or knobs to make the reticle
move. With this design, not only the errors of the two parts
themselves, but also their wearing out could cause inaccuracy to
adjusting the reticle. On the other hand, these devices all preset
a rated value as a moving scale. The moving unit is rated, which
represents a fixed value of the movement of the reticle. However, a
certain bullet impact point t does not have to be one of these
fixed moving scales; as a result, the reticle can only be
superimposed on the bullet's impact point approximately, but can
not fulfill the full superimposition theoretically. In practice,
the shooter could encounter a target at the range of more than one
thousand yards, but usually the superimposition of the impact point
and the reticle can only be done within a very short distance, such
as one hundred yards. Therefore, once the distance is over one
thousand yards, the error value of the approximate superimposition
will be quite big, which brings a lot of inconvenience to firing if
highly accuracy is required
[0008] A telescopic sight can only use one reticle shape, which
causes big limitation to shooting, because the different types of
firearms, bullets, and shooting environments in practical shooting
have different ballistic trajectory. Usually, the reticle image
used in a reflex sight is just one red or bright orange light spot.
Sometimes, a cross line, a light ring or other shapes are even
used. Their principles simply can not be adopted to set a reticle
scale based on ballistic trajectory. In current electronic sights,
the design of a reticle also follows the traditional one, at most
presetting or downloading some reticles, but never mentioning about
how to adjust a suitable reticle according to different ballistic
trajectories of different bullets. One thing is needed to point out
is that because the reticle in these electronic sights are either
downloaded from internet or designed by the user through computers,
if the user does not have correct knowledge about ballistics, he or
she probably will choose or design an incorrect reticle, and
directly lead to incorrect settings to the sight.
[0009] Another important factor of affecting aiming accuracy is a
clear view even in an environment with low intensity illumination.
However, current electronic sights have no any solution for the
problems. As for telescopic sights and reflex sights, the
limitation of optical theory does not allow the sight to capture
good quality images in the circumstances of low intensity
illumination.
SUMMARY OF THE PRESENT INVENTION
[0010] One objective of the present invention is to provide an
electronic firearm sight, which has a touch display screen used for
adjusting and determining an accurate and proper reticle, so as to
overcome the shortcoming of current technology.
[0011] According to the present invention, the electronic firearm
sight comprises a set of lens for capturing the optical image of an
aimed object, an image sensor for converting the optical image into
electronic signals, a processor for receiving the electronic
signals from the image sensor and processing them and other data, a
memory for storing different programs and data, and a touch display
screen for the operation of adjusting and determining a reticle,
once having received operation instructions from users, the touch
display screen sending the corresponding information to the
processor, and receiving and executing commands from the
processor.
[0012] There are pre-saved data or information in the memory of a
Cartesian coordinate system, ballistic trajectory data of different
bullets, and different reticle scales based on the different
trajectory data, and even different colors and shapes of the
reticle scales. These data or information is presaved to determine
a proper and accurate reticle.
[0013] Moreover, in order to overcome the problem of not being able
to view clearly long distance objects of existing sights, a set of
zoom lens are used. The creative combination of zoom lens and the
image sensor allows the long distance object display very clearly
on the screen, which not only gets the traditional telescopic sight
out of turning the magnifying ratio ring to enlarge images, but
also fills in the blank of existing electronic sights, which use
the digital magnification with the most magnification ration of
4.times..
[0014] In addition, the present invention further comprises a
rangefinder, which is for detecting and measuring the distance
between the aimed objects and the sight itself, and transmitting
corresponding data to the processor. These data are used, as one of
parameters, for the processor to analyze the location of a bullet
impact point and the reticle.
[0015] Likewise, the present invention further comprises a wind
speed & direction sensor connected with the processor for
detecting the speed and direction of wind, to detect the crosswind
and the wind speed, and transmitting corresponding data to the
processor. These data are used, as one of parameters for the
processor to analyze the location of the impact point and the
reticle.
[0016] Another objective of the present invention is to provide a
touch display screen used for adjusting the reticle of a firearm
sight described above. The touch display screen comprises a touch
screen, a display and a display driver. The touch screen comprises
a touch detection part and a touch controller. the touch display
screen is connected with a processor, which in turn is connected
with a memory; the memory has presaved a Cartesian coordinate
system, ballistic trajectory data based on different bullets, and
reticle shapes based on the trajectory data of different bullets;
once having received operation instructions from users about
adjusting the reticle, the touch display screen sends corresponding
information to the processor; once the processor finishing data
analysis and forming commands, the touch display screen receives
the commands and executes them.
[0017] Moreover, the touch display screen is connected with an
operation panel. On the operation panel are set operation buttons
for controlling the Cartesian coordinate system and reticle scales
of the trajectories formed based on different bullets, locking the
image of aimed objects, and zooming in or out the image.
[0018] Another objective of the present invention is to provide a
method of using the touch display screen described above to adjust
and determine the reticle of an electronic firearm sight, so as to
overcome the shortcomings of current technologies, which preset a
rated value as the basic value per unit movement of the
reticle.
[0019] According to the present invention, the method comprises the
following steps:
[0020] setting an object to fire;
[0021] calling up a Cartesian coordinate system saved in a memory
to the touch display screen, superimposing the Cartesian coordinate
over the image of the object, and setting the origin of the
coordinate at the center of the touch display screen;
[0022] viewing the image of the object through the touch display
screen, and aiming at the object with the origin of the
coordinate;
[0023] firing the first bullet toward the object to get a bullet
hole on it and viewing the corresponding scene through the touch
display screen;
[0024] locking the scene;
[0025] finding the corresponding place of the first bullet hole
appearing on the touch display screen;
[0026] obtaining the coordinate value of the corresponding place of
the first bullet hole appearing on the touch display screen;
[0027] determining the opposite value, on the touch display screen,
of the coordinate value of the corresponding place of the first
bullet hole;
[0028] clicking on the place of the opposite value on the
coordinate of the screen so as to move the origin of the coordinate
to the place of the opposite value;
[0029] unlocking the scene;
[0030] aiming at the object with the new origin of the moved
coordinate;
[0031] firing the second bullet, thereby the corresponding place of
second bullet hole appearing on the touch display screen;
[0032] locking the scene again;
[0033] removing the coordinate from the touch display screen;
[0034] clicking on the corresponding place of the second bullet
hole on the touch display screen, thereby a reticle appearing;
[0035] unlocking the scene.
[0036] Moreover, the method described above further comprise the
steps, after determining the place of the reticle, that choosing a
proper reticle shape based on the bullet type, the color and
brightness of the reticle, and the requirement for lines. These
steps can be operated through an operation panel.
[0037] The present invention has the following advantages.
[0038] By providing the firearm sight with a touch display screen
and a new method of applying the touch display screen to adjusting
and determining the reticle, the users can simply click the actual
bullet's impact point displayed on the screen, instead of using the
rated movement scale of the reticles of the existing technologies.
Therefore, it can fulfill real accurate superimposition of a
reticle and a bullet impact point, and eventually improve the
aiming accuracy greatly;
[0039] By applying zoom lens to the electronic firearm sight, the
optically amplified object can be displayed very clearly on the
screen, thereby opening up a new time of big magnification sight.
It is incredible to use a sight with the magnification rate of
36.times., or even 100.times. in the practical shooting, compared
to the at most 4.times. digital zoom of current electronic firearm
sights and at most 8.times. of telescopic sights.
[0040] It is worth mentioning that by adding a rangefinder and a
wind speed & direction sensor to the sight, plus the different
trajectory data pre-saved in the memory, the real automatic aiming
can become real, and even a shooter with poor skills can hit an
object accurately.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0047] As shown in FIG. 1, an electronic firearm sight 1 comprises
a set of optical lens 3, which captures the image of an object 2,
an image sensor 4 connected with the set of optical lens 3, which
converts lights into charges, a processor 6 connected with the
image sensor 4, which processes the image from the image sensor 4,
a memory 7 connected with the processor 6, which stores a variety
of information ready to be processed or having processed by the
processor, and a touch display screen 8, which receives operation
instructions given by a user 9 and sends corresponding information
to the processor, the processor analyzing and processing the
information, and then sending it back to and having it displayed on
the touch display screen.
[0048] Referring to FIG. 2, The lens 3 is a multiple of zoom lens,
which can change the focus through changing the relative places of
the lens, so that make the views at distance clearer. The lens 3
could be wide-angle lens, standard lens, telephoto lens, or fixed
focal length lens (FFL), or other lens made according to specific
requirements of the sight. The lens includes other components, such
as an aperture motor 15 for adjusting the aperture, a focus motor
16 for adjusting the focus, and a day/night vision shifting motor
17. Other lens components could be added. When an infrared led 18
is added to the lens, the day/night vision shifting motor 17
converts to the mode of might vision, so that the sight can be used
at night.
[0049] According to different demands, the image sensor 4 can be
charge-coupled device array (CCD array), complementary metal oxide
semiconductor (CMOS), or other types.
[0050] Referring to FIG. 2, the processor 6 is connected through
ADC 14 with an image driver 5 and the image sensor 4, so that ADC
14 converts the electrical signals of an image into digital
signals. The processor 6 includes an image-processing chip to
restore digital signals to an optical image, to superimpose an
adjusted reticle on it, and to display the superimposed image on
the touch display screen. The processor 6 is also connected with a
Flash 13, which stores program codes.
[0051] The memory 7 mentioned above is a RAM, in the present
embodiment.
[0052] Referring to FIG. 2 and FIG. 4, the touch display screen 8
comprises a touch screen 11, a display 10 and a display driver 9.
The touch screen 11 is connected with the processor through the
display 10 and a display driver 9.
[0053] As shown in FIG. 2, a rangefinder 20 and a wind speed &
direction sensor 19 are connected with the processor 6. The
rangefinder 20 is used to measure the distance between the object 2
and the sight 1 when the user has locked the object, through laser,
ultrasonic, red infrared ray or other chips of measuring distances,
and then to send corresponding data to the processor 6. The wind
speed & direction sensor 19 has a chip for detecting the wind
speed, delivering real-time wind speed to the processor. Therefore,
after comparing the ballistic trajectory data, the processor 6 can
calculate a new impact point and corresponding reticle place. For
example, according to pre-saved data, a bullet drops 4 cm at the
distance of 500 meters, and the real-time crosswind speed is 6 m/s
which cause the bullet to move left by 3 cm. Thus, modify the
deviation resulted from the drop of the bullet and wind speed,
based on the pre-saved data. After getting the new impact point,
show the new place with the modified reticle on the screen.
[0054] As shown in FIG. 2 and FIG. 3, the sight has an operation
panel 21 consisting of six function buttons, power switch 22, main
menu 23 lock 24, reticle brightness 25, screen brightness 26, and
magnification 27. The power switch 22 is connected with a battery
28, which provides electrical source and can be charged through a
battery charging port 29. The lock button 24 is for locking the
image of an aimed object. When the user needs to view and measure
the impact point after firing a bullet, the lock button needs to be
pressed. The magnification function 27 is used to magnify or reduce
the image of the object displayed on the display screen. The main
menu 23 includes the following options, coordinate, reticle,
rangefinder, wind speed &direction, and recorder. After
clicking on the reticle option, its sub-interface is popped up,
which includes settings of various parameters, such as reticle
type, reticle line, reticle color, and reticle shape, and et.; For
example, the reticle type includes general reticle, bullet drop
compensation reticle, and specially made reticle.
[0055] The sigh is also provided with a USB connector 30, a
removable memory card 31 and a video connector 32.
[0056] FIG. 5 is the flow chart of the method of the present
invention. The following
[0057] Referring to FIG. 5, and FIG. 6-FIG. 11, an embodiment of
the method of using the touch display screen to determine a proper
reticle is described as follows.
[0058] First, an object is set at a certain distance from the
sight. As shown in FIG. 6, when pressing the menu button on the
operation panel of the sight, and further clicking the coordinate
option, a coordinate 39 appears on the touch screen 11. Set the
origin 40 of the coordinate at the center of the screen, which is
the intersection of the diagonal of the screen. The user can view
the image 41 of the object through the screen, and aim at the image
41 with the origin 40 of the coordinate 39.
[0059] Next, fire the first bullet, and accordingly get the first
bullet hole 42, which is displayed on the screen, as shown in FIG.
7. Press the lock button on the panel to lock the instant
scene.
[0060] Referring to FIG. 8, read the value from the coordinate the
first bullet hole 42 on the screen, and find the opposite value 43
at the coordinate. Click the opposite value 43, so that the
coordinate 39 is moved to the place where the opposite value 43 is.
By doing so, the coordinate 39 has been moved from the center of
the screen to the place 43 of the opposite value of the actual
bullet impact point. Then, press the lock button on the operation
panel to unlock the scene, and aim at the image 41 with the new
origin of the moved coordinate again, which is the place of the
opposite value 43. Now the impact point, which was not at the
center of the screen, appears at the center of the screen and the
previous origin of the coordinate before being moved, which was at
the center of the screen, has been moved out from the center.
[0061] Referring to FIG. 9, now the user can fire the second bullet
and get the second bullet hole 44. The second bullet hole 44
appears at the center of the screen and, theoretically, it will be
superimposed with the first bullet hole 42. Lock the instant scene
again.
[0062] Referring to FIG. 10, remove the coordinate, and click on
the second bullet hole 45 on the screen, the figure of a reticle 45
appears at the place. Then, unlock the instant scene.
[0063] Referring to FIG. 11, based on the place of the reticle of
last step, the user can modify the reticle with a certain shape,
color, line, brightness of the reticle and the screen through the
operation panel to get a suitable reticle. For example, the user
can choose a suitable color for the reticle in order to make the
reticle outstanding in the environment background.
[0064] The embodiment described above is to adjust the bullet
impact point so as to be located at the center of the screen. If
hoping the reticle to appear at any desired place, instead of the
center of the screen, the user, after getting the first bullet
impact point, simply just finds the opposite value of an adjusted
amount the user desires and aims at the opposite value with the new
origin of the moved coordinate. Then fire the second bullet to get
the second bullet hole, which is at the ideal place of the screen.
Finally, click on the second bullet hole on the screen and a
reticle at the ideal place appears.
[0065] Therefore, within the range the screen can display, the user
can adjust the reticle until the reticle appears at a desired
point.
[0066] Because of the brand-new adjusting method, the user can make
the impact point return to the origin at any distance and in any
shooting circumstances, which makes the task of time consuming,
bullet consuming, and rarely being done with accuracy be
easier.
