DETAILED DESCRIPTION

The ensuing description provides preferred exemplary embodiment(s) only, and is not intended to limit the scope, applicability or configuration of the disclosure. Rather, the ensuing description of the preferred exemplary embodiment(s) will provide those skilled in the art with an enabling description for implementing a preferred exemplary embodiment. It is understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope as set forth in the appended claims.

Embodiments described herein are generally related to fire-control display adapters for a scope of a weapon. In particular, some embodiments of the disclosure describe assisting in shooting a target. The assistance is provided by generating a ballistic solution and displaying the ballistic solution on a display unit. The display unit is configured such that a user can see information associated with the ballistic solution as an overlay on the objective lens while the user is looking at a target through an ocular lens of the scope. The user can then have a shot at the target by adjusting the position of the weapon according to the ballistic solutions displayed on the display unit.

The presentation of the ballistic solution as the overlay on the objective helps a shooter to adapt to an appropriate shooting position on a battlefield to shoot the target with accuracy while considering environmental conditions, such as range to the target, wind speed, temperature, atmospheric pressure, elevation, cant, etc.

Referring to FIG. 1 illustrates a military environment 100 that includes elements for generating and assisting a shooter or a combat sniper to shoot a target. For example, the military environment is a simulation environment for training the combat sniper to shoot at the target at long ranges under different environmental conditions. The military environment 100 includes a weapon 110, a fire-control display adapter 120, a communication network 130, three spotter equipment 140-1, 140-2, 140-3, and a command center 150.

In the military environment 100, the combat snipers are entailed to work in close coordination with a spotter as part of a sniper team. The spotter provides protection and situational awareness for the sniper, since the sniper devotes substantial energy and attention to positioning the weapon for an effective shot. The spotter uses the spotter equipment 140, which carries all the imperative programs and hardware configuration to receive data from the fire-control display adapter 120. The spotter equipment then displays the data in a format, such that the spotter can understand and analyze the range to the target under different environmental conditions. After the analysis, the spotter then provides aiming information to the combat sniper via the communication network 130. The aiming information includes instructions to correctly orient the weapon 110 towards the target. In an example, the fire-control display adapter 120 is provided with cameras to relay live video feed to the spotter equipment 140 via the communication network 130. In another example, the fire-control display adapter 120 is connected with thermal imaging sensors mounted on the weapon 110, to relay live video feed to the spotter equipment 140 via the communication network 130. As used herein, the term “spotter equipment” may refer to a wireless device, a machine-to-machine (M2M) device, a mobile phone, a cellular phone, a Personal Digital Assistant (PDA) equipped with radio communication capabilities, a smartphone, a laptop or personal computer (PC) equipped with an internal or external mobile broadband modem, a tablet PC with radio communication capabilities, a portable electronic radio communication device, and/or an electronic device equipped with radio communication capabilities or the like for communicating with a sensor device. The sensor device may be any kind of weather sensor, such as wind, temperature, air pressure, humidity, etc. As further examples, the sensor may be a light sensor, an electronic or electric switch, a microphone, a loudspeaker, a camera sensor, etc.

In some embodiments, the sensor data is embedded into the video feed in accordance with governing standards and protocols. The standards are protocols are dependent on various jurisdictions. For example, a Motion Imagery Standards Board (MISB) standard 0601 is one such standard indicating how sensor data is embedded into the video (e.g., as a real-time, synchronous MISB key-length-value (KLV) stream). In some other embodiments, alternative standards may be used depending on desired functionality.

In addition to the above the fire-control display adapter 120 communicates with command center 150 via the communication network 130. For example, command center 150 refers to a central place for carrying out orders and for supervising tasks for the sniper team.

In some embodiments, the communication network 130 refers to a short-range communication network, for example, a Bluetooth™ communication network. In some embodiments, a specific distance of a preset communication distance may be set according to actual requirements, and the embodiments of the present application are not limited thereto. For example, in the case where the preset communication distance is 10 meters, the wireless communication network may be a Bluetooth™ communication network.

In some embodiments, the communication network 130 may refer to a long-range network that uses wireless data connections for connecting network nodes, for example, Wi-Fi access points, and enabling telecommunications between the network nodes. The cellular wireless communication network implements, for example, a long-term evolution (LTE) technology, and for purposes of illustration, is hereafter referred to as an “LTE network”. Also, as used herein, “cellular wireless communication interface” refers to a wireless wide area network (WWAN) interface of the cellular wireless communication network between the display adapter 120 and the command center 150. For example, wireless communication works on a wireless communication technology that supports high-speed data transfer.

Referring to FIG. 2, illustrates a block diagram of the fire-control display adapter 120 as described in FIG. 1. The fire-control display adapter 120 includes a display unit 200, a ballistic computer 202, a distance sensor 204, a power source 206, an accelerometer 208, a gyroscope 210, a magnetometer 212, an interface 214, a windage sensor 216, and a temperature sensor 218, a photoelectric sensor 220, a pressure sensor 222, a spotter API 224, a communication interface 226, an infrared camera 228, an image sensor 230, and a user interface (UI) processor 232 or UI processor 232.

The term “ballistic computer” used herein refers to an electrical circuit or integrated circuit or circuit chip, in which the conductors are printed or deposited in predetermined patterns on an insulating substrate. In other words, the ballistic computer 202 is an integrated circuit that houses embedded circuitry that can transmit, receive, and process data received from multiple electronic components or devices. The ballistic computer 202 is in operable communication with an array of sensors, such as orientation sensors, range sensors, and environmental sensors. In some embodiments the sensors are selected from a group of the accelerometer 208, the gyroscope 210, the magnetometer 212, the windage sensor 216, the temperature sensor 218, the photoelectric sensor 220, the pressure sensor 222, the infrared camera 228, the image sensor 230, the distance sensor 204. In some embodiments, the distance sensor 204 is external to the fire control display adapter 120. In some embodiments, the sensors are communicably coupled to an external computer.

In some embodiments, the distance sensor 204 is selected from a group of an infrared rangefinder, a laser rangefinder, and an ultrasonic rangefinder. The distance sensor 204 senses a range to an aimpoint of a target. In some embodiments, the ballistic computer 202 is configured to process data associated with the orientation of fire control display adapter 120, process data associated with the orientation of the weapon 110, and calculate ballistic solutions. The ballistic computer 202 is communicably coupled to the display unit 200 and the distance sensor 204 to calculate a ballistic solution and cause the display unit 200 to display the ballistic solution. The ballistic computer 202 communicates with the display unit via interface 214. The display unit 200 is positioned at an objective bell of a scope and is aligned in front of an objective lens of the scope. In some embodiments, the display unit 200 is selected from a group of a liquid crystal display, a digital micromirror display, an organic light emitting diode display, and a quantum dot display. The power source 206 is communicably coupled to the ballistic computer 202 to provide power to the distance sensor 204 and the display unit 200.

In the embodiment illustrated, the ballistic computer 202 is communicatively coupled to control many of the other components. In some embodiments, the processing is further divided between sub-processors of the ballistic computer 202, which may include a rangefinder codec. The processing may be further consolidated or distributed, depending on desired functionality. Depending on desired functionality, the ballistic computer 202 may comprise one or more application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), a general purpose processor, or the like. The UI processor 232 is communicatively coupled with the spotter API 224. In some embodiments, the UI processor 232 may be communicatively coupled with a wired or wireless interface, which can enable fire control display adapter 120 to communicate with another device. In some embodiments, a wireless interface or communication interface 226 is configured to enable communication between the ballistic computer 202 and a display device external to the fire-control display adapter 120. In some embodiments, wireless communication may be implemented via an IR interface. In some embodiments, communication may be implemented via wired communication, such as an RS252 serial port. The communication interface 226 is configured to transmit data from the ballistic computer 202 to an electronic device that is not mechanically coupled with fire control display adapter 120. In some embodiments, the electronic device is a display device operated at the command center disp 150. In some embodiments, the communication interface 226 is Bluetooth™ interface. In some other embodiments, the communication interface 226 is a Wi-Fi interface.

In operation, a sniper carrying the weapon 110 is entailed to switch on the ballistic computer 202 of the fire-control display adapter 120. For switching on the ballistic computer 202, power is entailed which comes from the power source 206. For example, the power source 206 is a battery positioned at a grip of the weapon 110. In another example, the power source 206 is an electrical connector to receive power from a source external to fire control display adapter 120. Once the ballistic computer 202 is switched on, the power is further transferred to all the electronic components, such as sub processors and the sensors of fire control display adapter 120.

The display unit 200 displays a range to the aimpoint of the target, where the laser range finder can transmit a laser beam through a transmission unit and receive a reflected laser beam through a receiver unit. The total time of the reflected laser beam is calculated by the ballistic computer 202 to determine the range to the aimpoint of the target. A variety of lasers with accompanying collimating optics may be used with the desired wavelength, diffraction, and other optical traits to enable range-finding and wind-sensing measurements at operating distances.

The display unit 200 displays the ballistic solution, in which the orientation of the weapon/and or fire control display adapter 120 is also displayed. Hence the accelerometer 208, the gyroscope 210, and the magnetometer 212 are activated by the ballistic computer 202 to identify parameters related to elevation, azimuth angles, tilt angles, and/or rotation (“cant”) angles.

The display unit 200 further displays the ballistic solution based on environmental factors, such as wind, temperature, air pressure, and humidity. Since these environmental factors influence a bullet drop and horizontal targeting, the windage sensor 216, the temperature sensor 218, and the pressure sensor 222 calculate numerical values related to the environmental factors.

The range, parameters, and numerical values are automatically measured in real-time and may be overlayed as text or graphics on the objective lens of the scope. Further to this, the range, parameters, and numerical values are taken as inputs by the ballistic computer 202 to display the ballistic solution to the sniper through the ocular lens of the scope. The sniper can then align the weapon towards the virtual targeting reticle to go for an accurate shot.

In some cases, the sniper may be entailed to operate at night or in places with poor light conditions. In addition to this, there may come a requirement of relaying a live video feed of the location and surroundings of the target. For countering such hurdles the ballistic computer 202 uses the photoelectric sensor 220 to determine activating either the infrared camera 228 or the image sensor 230, for example, a video camera. For example, the photoelectric sensor 220 indicates a low-light condition, then the infrared camera 228 is activated as the infrared camera 228 measures temperatures of object surfaces and functions on infrared thermography. The infrared thermography is a passive imaging method for contactless temperature measurement. In another example, the photoelectric sensor 220 indicates optimal lighting conditions for recording scenes for the live video feed, in such case the image sensor 230 is activated to record the scenes. In one scenario, a combination of thermal and night vision technologies may be entailed to be used in tandem in order to optimize sighting pictures in all environments and scenarios. In such cases both the infrared camera 228 and the image sensor 230 can be activated by the ballistic computer 202 at the same time to perform the infrared thermography and the videography simultaneously. For this, ballistic computer 202 may be provided with such instruction via the UI processor 232. The UI processor 232 enables the functioning of instructions received from a device carrying the user interface for operating the ballistic computer 202. The device may be the spotter equipment 140-1, 140-2, or 140-3. In some embodiments, the ballistic computer 202 is manually operated by input units or buttons or switches positioned on the display adapter. In some embodiments, ballistic computer 202 is controlled by the spotter equipment 140-1, 140-2, 140-3, and/or the command center 150 of FIG. 1.

The fire control display adapter 120 is mounted on the rail of the weapon 110 such that the display unit 200 works in tandem with accessories or sensors mounted on the weapon 110. The sensors may include imaging sensors, including but not limited to thermal, night vision, mid-wave, and complementary metal-oxide semiconductors). In some embodiments, a magnified liquid crystal display or a viewfinder display is clipped side by side on the eyepiece 308 of the scope 300 with the same eye relief and focal point to the eye when operating the scope 300.

In some embodiments, a live video feed from the image sensors mounted on the weapon 110, is relayed on the display unit 200, where the live video feed is overlayed with all related targeting information at sides and top areas (range, cant, elevation, azimuth, wind speed, hold values, and ballistic parameters. In some embodiments, the ballistic computer 202 is configured to process images from the live video feed to reduce image tear due to weapon movements and display an electronic aimpoint on the target scene. In some embodiments, the ballistic computer 202 is configured to reduce scintillation blur and track a target for lead angles and tracking. An accurate aimpoint is then displayed on display unit 200. Such arrangements eliminate the need to automatically adjust a text font size proportional to a zoom level of the scope 300. The sniper no longer needs to manually re-adjust the text font size of the display unit 200 to the zoom level of the scope. This reduces target engagement time and allows rapid updates and timely shots to the target.

As described above, the spotter equipment 140-1, 140-2, 140-3 may communicate with the ballistic computer 202, where the spotter API 224 receives the instructions from the spotter equipment 140-1, 140-2, 140-3, which are processed by the UI processor 232 and are further transmitted to the ballistic computer 202. The spotter API 224 defines a protocol for communicating information related to control operations by the spotters and between the spotter equipment 140-1, 140-2, 140-3, and the ballistic computer 202. The API refers to a software interface that provides a means for a software application or a client application (e.g., the spotter equipment 140-1, 140-2, 140-3, or the command center 150) to communicate with a remote application, installed the spotter equipment 140-1, 140-2, 140-3 or the command center 150 over, a network (e.g., the Internet) through a series of programming commands that call and/or invoke a routine to execute a specific process. In some embodiments, the API may communicate back and forth between the spotter equipment 140-1, 140-2, 140-3, and the ballistic computer 202. In some embodiments, the API uses a secured tunnel. The secured tunnel is a communication link that is encrypted and is used to transmit and receive data over an encrypted connection. The encrypted connection helps to maintain the privacy of control operations.

Referring to FIG. 4B and FIG. 4C illustrates side views of the fire control display adapter 120 mounted on the scope 300 of the weapon 110 according to an embodiment of the present disclosure.

As shown in FIG. 4B, the fire control display adapter 120 comprises a portion 400 that includes the display unit 200. When fielded, the objective bell 314 of the scope 300 is positioned inside the portion 400 to align the objective lens 306 and the display unit 200 in front of each other. The fire control display adapter 120 further comprises a second portion 402, which houses a transmission unit of the laser range finder 204. The fire control display adapter 120 further comprises a third portion 404, which houses a receiver unit of the laser range finder 204. The fire control display adapter 120 further comprises a mount 406 to detachably secure the fire control display adapter 120 on a rail of the weapon 110.

The fire control display adapter 120 further comprises an infrared range sensor to determine a distance between two targets. The IR range sensor is communicably coupled to the ballistic computer 202 and performs continuous emission of an infrared beam by an infrared light emitting diode 408a onto a first target and a second target. The emitted infrared beam is reflected by the first target and second target, and the reflection is detected by a photocell 408b sensitive to an infrared beam. Further based on the principle of triangulation, the distance between the first target and the second target is determined.

As shown in FIG. 4B and FIG. 4C, the mount 406 includes an adjuster 410 to adjust the fire-control display adapter 120. The adjuster is positioned between the mount 406 and the portion 400. The adjuster 410 performs vertical adjustment of the fire control display adapter 120 with respect to the rail of the weapon 110 and/or with respect to an optical path and/or an ocular lens 304 of the scope 300. The adjuster 410 comprises a first bolt 410a, a second bolt 410b, and a ring 412. A lateral surface of the first bolt 410a is provided with threads.

A second end of the first bolt 410a is covered by the ring 412.

In use, the sniper can rotate the ring 412 to either bring together the first bolt 410a and the second bolt 410b or move the first bolt 410a and the second bolt 410b away from each other. Such movement of the first bolt 410a and the second bolt 410b enables vertical adjustment of the fire control display adapter 120 with respect to the rail of the weapon 110.

In some embodiments the adjuster 410 function on a differential screw arrangement. In some embodiments, the adjuster 410 function on a wedging mechanism.

Referring to FIG. 5A and FIG. 5B, illustrate schematic views of the display unit 200 working in tandem with the ocular lens 304 of the scope 300 according to an embodiment of the present disclosure. FIG. 5A shows an example view 500A provided by scope 300. View 500A shows a view of a long-range target area as seen through scope 300 prior to mounting In some embodiments. Shooting accurately at long ranges is not as simple as lining up a crosshair 502 at the center of target 504 in the target area 506. For example, the environment between scope 300 and target area 506 may include strong left crosswinds. Additionally, long-range shots need to take the effect of gravity into account, which causes a shot to drop between the weapon and the target area 506. A magnetic heading of the weapon may also affect long-range shots. A shot taken under these circumstances would drop and may lead to an inaccurate shot because of the strong crosswind and effect of gravity over a long distance to the target area 506. The sniper could approximate the aimpoint based on an estimation of the strength of the left cross-wind and the distance to the target area 506. The sniper could then use the aimpoint by manually aligning the crosshair 502 above and to the left of the target 504.

As shown in FIG. 5B, to accurately hit the target in the target area 506 when using the scope 300, the sniper would need to approximate the aimpoint above and to the left of the target 504. The shooter could approximate the aimpoint based on an estimation of the strength of the left cross-wind and the distance to the target area 506. The sniper could then use the aimpoint by manually aligning the crosshair above and to the left of the target 504.

Referring to FIG. 6, illustrates a schematic representation of a screen mirroring of the display unit 200 on the spotter equipment 140 according to an embodiment of the present disclosure. The sniper can use an assisting spotter to use a ballistic computer in conjunction with the display unit 200 and connected via the communication network. Here the spotter could simultaneously analyse windage, elevation, azimuth angles, tilt angles, and/or rotation (“cant”) angles in real time and instruct the sniper to orient the weapon 110 in a particular direction or order.

In use, the ballistic computer 202 processes data and calculates a ballistic solution. The communication interface 226 transmits the ballistic solution data to be displayed on the spotter equipment 140.

Referring to FIG. 8, illustrates a side view of the fire control display adapter 120 mounted on the weapon 110 according to an embodiment of the present disclosure. The fire control display adapter 120 comprises the adjuster (not shown) arranged between the surface of the mount 406 and the portion 400 to adjust the fire control display adapter 120 with respect to the optical path and/or the ocular lens 304. Further the mount 406 is slidably moves on a rail 800 of the weapon 110 to attach the fire control display adapter 120 to the weapon 110. The fire control display adapter 120 is attached to the weapon such that the display unit (not shown) is aligned in front of objective lens of the scope 300. For example, the rail 800 is one of a Picatinny rail and a weaver rail. In some embodiments, the adjuster comprises a coupling mechanism that includes a bolt and a nut.

An engagement between the adjuster 410 and the scope 300 can be adjusted according to the size of the tube 302 and according to the size of the eyepiece 308 or objective bell 314, as different scopes may have different dimensions and configurations. For example, scope 300 has a rectangular shape. In another example, scope 300 has a circular shape. In yet another example, the scope 300 has a square shape.
