The disclosure relates to viewing optics, and more particularly to viewing optics having an integrated direction sensor with wind direction capture capability. In another embodiment, the disclosure relates to a method for utilizing a viewing optic with an integrated direction sensor with wind direction capture capability.
Previous viewing optics, such as laser rangefinders, which include integrated ballistics calculators, require a user to either manually input wind direction or have an external device connected to the viewing optic. Manually inputting the wind direction into a viewing optic is very cumbersome and highly inaccurate. The speed and direction of the wind are very important factors in calculating a ballistics solution. Just as important is the timeliness of inputting this information before wind direction changes or the target moves.
Generally, wind direction is observed and/or measured on a first device, then manually inputted into the viewing optic. For example, consider a hunter trying to shoot a deer at 750 yards. The hunter gets a ballistic solution based on 8-mph winds at 75° relative to the hunter, and this data was previously inputted. Just prior to pulling the trigger, the wind changes direction and is now 130° relative to the hunter. If the hunter had to manually input wind direction again by cycling through multiple menus and then updating the wind information, there is a good chance the hunter will not be able to take his/her shot.
Wind direction is only one factor used by ballistics calculators to determine a bullet's trajectory. Additional environmental factors, such as barometric pressure, humidity, and temperature also affect a bullet's trajectory. In many instances, a user must carry multiple instruments in order to capture the environmental data desired to be inputted into a ballistics calculator to generate a more complete ballistic trajectory.
The same scenario(s) can also be applied to competition shooting, in which each shooter s timed on his/her shots and must make quick adjustments. Prior to taking a shot, the shooter quickly enters all environmental parameters. Typically, wind direction and speed are the only parameters that are not directly inputted into the ballistics calculator. Therefore, the shooter must quickly input them and set up to shoot the target. If the wind changes direction or speed just prior to taking the shot, the shooter will need to input new wind data into the ballistics calculator onboard the viewing optic.
The following is an example of the steps required to input a 10-mph wind speed coming from a direction of 320° as referenced from true North:
As outlined above, viewing optics with onboard ballistic calculators require the user to navigate multiple menus to input the wind direction and speed and/or use multiple instruments to obtain the information necessary to complete a ballistic calculation. Thus, a need still exists for a viewing optic, such a binocular or monocular, that can quickly obtain wind direction and/or eliminate the need for a user to carry multiple instruments.

In the embodiment shown, the viewing optic 100 includes a menu button 1, a measure button 2, a wind capture button 3, and first and second selection buttons 4, 5, respectively. The viewing optic 100 further includes onboard rangefinder functionality. The menu button 1 allows a user to access the onboard rangefinder functionality and, for example, enter and/or exit various modes. The measure button 2 is used to fire the laser in order to obtain a range to an intended target. The wind capture button 3 is used to enter and/or exit a mode, which permits the capture of the wind direction and/or capture the wind speed. The first and second selection buttons 4, 5 allow users to navigate through menus and/or, when in wind capture mode, to increase and/or decrease, wind speed.

Menu selection would then be the selected value or data input for that parameter, and could be provided by scrolling or clicking through options that could be selected, or could even be entered manually into the viewing optic itself or through data input from another device. In one embodiment, the menu option allows for the selection of range units, and the user can choose from menu selections for yards or meters.
In an embodiment, a viewing optic 100/100′ further includes an integrated direction sensor, such as a compass (not shown). The direction sensor may be independent from the ballistics calculator or, in further embodiments, in communication (either directly or indirectly) with the ballistics calculator. In the particular embodiments shown, the direction sensor is operatively coupled to the wind capture button 3. Activation of the wind capture button 3 causes the wind direction to be measured and/or captured.

In one embodiment, the direction of the target is computed against the captured wind direction.
In one embodiment, the direction sensor determines the direction to the target in relation to the direction of the captured wind, which can be stored in one or more memory devices.
In an embodiment, a viewing optic 100/100′ further includes a ranging system (not shown). A standard ranging system uses a laser beam to determine the distance to an object or to a target, and operates by sending a laser pulse towards target and measuring the time taken by the pulse to be reflected off the target and returned. In general terms, a laser pulse is emitted from a transmitter, such as a pulse laser diode. Part of the beam emitted travels through a beam splitter, and part is reflected to detector. The emitted laser pulse travels through a transmission lens to target, which reflects a portion of the laser pulse back through receiving lens and subsequently through receiver to a micro-controller unit, which calculates the distance to target using well, known mathematical principles. Ranging system could also be a more complex system with additional or alternative components, including gain control components, charging capacitors, and analog to digital converters by way of example.
In an embodiment, the viewing optic 100/100′ further includes at least one sensor of an anemometer, a barometric pressure sensor, a humidity sensor, and a temperature sensor. In a preferred embodiment, the viewing optic 100/100′ includes at least one, at least two, at least three, or all four of an anemometer, a barometric pressure sensor, a humidity sensor, and a temperature sensor. These sensors are operatively coupled to the ballistic calculator such that the ballistics calculator can utilize the data captured by the one or more sensors in determining a bullet trajectory.
In a further embodiment, the one or more sensors are operatively coupled to a memory device. The memory device stores the data captured by the one or more sensors.
In still a further embodiment, the one or more sensors are operatively coupled to the display so that the data captured by the one or more sensors is capable of being displayed.
In one embodiment, ballistic parameters associated with temperature, barometric pressure, humidity, altitude and ambient light conditions are sensed by a thermometer, barometer, hygrometer, altimeter, and light meter, respectively. The digital readings sensed from each of these digital ballistic parameter instruments are also configured to be transmitted (e.g., in real time) to a processor having a ballistics computer program.
In one embodiment, the viewing optic can have an inertial navigation unit including but not limited to a 3-axis compass, a 3-axis accelerometer, and a 3-axis gyroscope. In other embodiments, the 3-axis compass, a 3-axis accelerometer, and a 3-axis gyroscope can be incorporated into the viewing optic 100/100′ as individual components, with appropriate software, instead of being incorporated into the viewing optic 100/100′ as an integral unit. And in still other embodiments, the gyroscope can be omitted. Further, other tilt sensors can be used in place of the accelerometer. Examples of other tilt sensors include an electrolytic liquid level tilt sensor, an optical bubble tilt sensor, a capacitive bubble tilt sensor, a pendulum mechanism, a rotary optical encoder, a rotary electro-resistive encoder, a Hall Effect device, and a ceramic capacitive tilt sensor.
In one embodiment, the viewing optic 100/100′ has a processor or a computing device containing a ballistics calculator or ballistics computer program that the user can access using one or more buttons operatively connected to the ballistics calculator to determine a projectile's trajectory based on one or more factors such as projectile weight, distance to target and environmental factors (such as, for example, wind speed and wind direction).
In one embodiment, the ballistics calculator computes a ballistics solution using two variables obtained from the direction sensor: (1) direction the wind originates; and (2) direction to the target. In one embodiment, the direction to the target is captured at the same time the distance to the target is determined by the ranging system. In one embodiment, the direction to the target is computed against the captured wind direction.
In one embodiment, the processor containing a ballistics calculator program can receive one or more aspects of ballistics data including but not limited to information regarding external field conditions (for example, date, time, temperature, relative humidity, target image resolution, barometric pressure, wind speed, wind direction, hemisphere, latitude, longitude, altitude), firearm information (for example, rate and direction of barrel twist, internal barrel diameter, internal barrel caliber, and barrel length), projectile information (for example, projectile weight, projectile diameter, projectile caliber, projectile cross-sectional density, one or more projectile ballistic coefficients (as used herein, “ballistic coefficient” is as exemplified by William Davis, American Rifleman, March, 1989, incorporated herein by reference), projectile configuration, propellant type, propellant amount, propellant potential force, primer, and muzzle velocity of the cartridge), target acquisition device and reticle information (for example, type of reticle, power of magnification, first, second or fixed plane of function, distance between the target acquisition device and the barrel, the positional relation between the target acquisition device and the barrel, the range at which the telescopic gunsight was zeroed using a specific firearm and cartridge), information regarding the shooter (for example, the shooter's visual acuity, visual idiosyncrasies, heart rate and rhythm, respiratory rate, blood oxygen saturation, muscle activity, brain wave activity, and number and positional coordinates of spotters assisting the shooter), and the relation between the shooter and target (for example, the distance between the shooter and target, the speed and direction of movement of the target relative to the shooter, or shooter relative to the target (e.g., where the shooter is in a moving vehicle), and direction from true North), and the angle of the rifle barrel with respect to a line drawn perpendicularly to the force of gravity).
In an embodiment, the viewing optic 100, and particularly the ballistics calculator, has at least two user-selected modes, including but not limited to a “ballistics” mode. Ballistics calculations are extremely important to shooters at distances beyond 500 yards. At these distances, the effects of gravity, bullet characteristics, gun characteristics, temperature, barometric pressure, relative humidity, wind direction, and wind velocity have a greater impact on the overall trajectory of the bullet.
In one embodiment, the processor can also be fed wind data, temperature data and other environmental field data from a remote sensing device. In one embodiment, the remote sensing device may be wirelessly linked to the processor. The processor may determine one or more ballistic parameters from the data gathered from the range finder and an inclinometer and the remote sensing device and then calculate the required Point of Aim (POA) to Point of Impact (POI) adjustment based on these ballistic parameter(s). The processor may then transmit a data signal representative of the required or desired vertical and windage adjustment for the POA to POI adjustment to a display. As described herein, such communication of the signal between the processor and the display may be achieved by either a wire-based link or a wireless link.
In an embodiment, a viewing optic 100/100′ further includes a memory device (not shown). A memory device may be internal to, so as to be contained within, the viewing optic 100/100′ or external to and in communication (either wired or wireless) with the viewing optic 100/100′. In such embodiments, the memory device is operatively connected to both the direction sensor and the ballistics calculator. In embodiments, the connection with the direction sensor and/or ballistics calculator may be wired or utilize wireless communication technologies. In embodiments having a memory device, the captured wind direction data may be stored in the memory device and accessible to the ballistics calculator.
Furthermore, with the wind direction captured and stored, the user can continuously range targets and have a wind corrected ballistics solution, unless the wind direction or speed changes. However, if the wind is steady, the user only has to range a new target, which provides a simple and efficient process to obtain a wind corrected ballistics solution.
In an embodiment, a viewing optic 100/100′ includes a display. The display may be integrated within the sight of the viewing optic 100/100′ or visible on the exterior of the viewing optic 100/100′. In still further embodiments, the display may be a separate component from the viewing optic 100/100′, such as a computer, tablet, mobile phone, television or other device, and in communication with the viewing optic 100/100′. The display is configured to show various information, including menu options and ballistics data.
In a particular embodiment, the display is configured to display the distance to a target. For example, when a viewing optic 100/100′ includes laser rangefinder functionality, as described above and with particular reference to measure button 2, the ballistics computer will calculate the distance to a target. When the measure button 2 is activated (e.g., pushed), the viewing optic 100/100′ will emit a laser beam which the user directs toward a desired target. The laser beam reflects off the target and back to the viewing optic 100/100′. The ballistics computer calculates the distance from the viewing optic 100/100′ to the target based on the signal strength and time it took to receive the reflected beam.
In a further embodiment, the viewing optic 100/100′ includes an inclinometer. In such embodiment, the display may be configured to display the elevation angle of a target.
It will be appreciated that the specific shape, arrangement and physical design of the buttons 1-5 described herein may vary, provided the buttons 1-5 are operatively connected to the onboard rangefinder system(s) to permit functionality.
In an embodiment, the viewing optic 100/100′ assists a user in compensating for wind direction and velocity.
As set forth above, wind direction and velocity can have a significant effect on bullet trajectory. Additionally, barometric pressure, ambient temperature, and relative humidity also affect trajectory. While the range from the shooter to the target is often the most important factor, each of the environmental factors listed above can greatly influence trajectory. The table below illustrates the effects of changing some of these parameters by 10%.
Indeed, Table 1 shows that changing the range to the target has the greatest influence on trajectory, followed by barometric pressure and wind speed. For example, when using a particular firearm, with a given ammunition and a consistent target at 1,000 yards, the wind direction and velocity can greatly impact the travel of the bullet even up to 80 inches or more. By way of specific example, the following values show the effect wind can have on bullet trajectory based on a user shooting at a target at 1,000 yards with a Winchester 0.308 rifle, Hornaday ELD-X 178 grain bullet, rifle zero range of 100 yards, muzzle velocity of 2,650 feet per second, 29.08 in Hg barometric pressure, 70° F. temperature and 60% relative humidity:
The above scenarios show just how much a 10 mph wind affects bullet trajectory when coming from different directions. It will be appreciated that the greater the distance to the target, the greater the effect of the wind on bullet trajectory.
First, a mode that allows wind direction to be captured using a direction sensor is accessed. In an embodiment, the step of accessing the mode 305 includes pressing and holding a button (or pressing a specific sequence of buttons) to enter a mode that will allow the wind direction to be captured using the direction sensor. In an embodiment, the specified button is a wind capture button 3 as described herein. In an embodiment, the step of pressing and holding the specified button 305 includes pressing and holding the specified button for a specified time, e.g., from 3 to 6 seconds, and more preferably from 3 to 5 seconds. To note, step 305 may not be necessary if the wind capture mode is already accessed.
Next, the viewing optic is pointed in the direction the wind is coming from (step 310).
Once the viewing optic is in the proper mode and pointed in the proper direction, the user presses a button to capture the wind direction (step 315). In an embodiment, the button may be the same as the specified button of step 305. In a further embodiment, the button is a wind capture button 3 as described herein. In an embodiment, the step of pressing a button to capture wind direction includes pressing and holding the button for a specified time, which is generally less than the specified time of step 305, e.g., less than 2 seconds, or more preferably less than 1 second.
In an embodiment, the step of pressing a button to capture wind direction 315 further includes automatically inputting the wind direction data to the viewing optic's onboard ballistics calculator and/or a memory device.
Step 320 is pressing a button or buttons to manipulate the wind speed value. In an embodiment, a viewing optic includes two buttons, such as the first and second selection buttons 4, 5 described above, one of which serves to allow a user to increase the wind speed value and the other to decrease the wind speed value.
Next, a range value is obtained (step 325) by activation of the ranging system. In addition, upon activation of the ranging system, the direction sensor will also capture the direction to the target. In an embodiment, the step of obtaining a range value includes aiming the viewing optic at a target and pressing a specified button to take a range. At the same time, the direction sensor determines the direction to the target.
In an embodiment, the specified button is a measure button 2 as described herein. In an embodiment, the step of pressing the specified button 325 includes pressing and holding the specified button, such as, for example, for a period of time necessary to obtain a consistent measurement. In an embodiment,
Optionally, a specified button is pressed and held (or a sequence of buttons is pressed) in a final step 330 to exit the input modes. In an embodiment, the specified button is a menu button 1 as described herein. In an embodiment, the step of pressing and holding the specified button 330 includes pressing and holding the specified button 330 for a specified time, e.g., from 3 to 6 seconds, or preferably from 3 to 5 seconds. While useful to exit the ballistics calculator mode after setting each of the parameters described above, doing so is generally not required in order to use a viewing optic.
In a further embodiment, the method further includes the steps of pressing (and in some instances also holding) a specified button to enter/exit different modes to capture and/or display information obtained from additional sensors, including but not limited to, an anemometer, a barometric pressure sensor, a humidity sensor, and a temperature sensor. The steps associated with capturing and/or displaying data obtained from an anemometer, a barometric pressure sensor, a humidity sensor, and a temperature sensor can be completed either before step 305, 320, 325 or 330, or after step 330. The information captured with one or more of the sensors can be stored on a memory device.
In other embodiments, the method includes the steps of automatically capturing data from one or more sensors of an anemometer, a barometric pressure sensor, a humidity sensor, and a temperature sensor using the ballistic calculator. When the data from an anemometer, a barometric pressure sensor, a humidity sensor, and a temperature sensor is captured automatically, the data may be captured simultaneously with any of steps 305-330 or before or after any of steps 305-330.
One will appreciate that the methods and structures disclosed herein increase the accuracy and timeliness of shots even if wind direction and speed remain constant. Allowing a user to simply point the viewing optic into the direction of the wind, and having the wind information stored in a memory device, allows the ballistics calculator to reference the direction for all ranges regardless of orientation of the viewing optic.
