Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application is a nonprovisional application and claims priority to U.S. Provisional Patent Application No. 63 / 362,177, filed March 30, 2022, which is incorporated by reference in its entirety.

[0002] (Technical field) The present disclosure relates to a user interface for inputting wind direction and speed information, and more particularly, to a user interface for inputting wind direction and speed information for use with a ballistic calculator. In one embodiment, the present disclosure relates to a viewing optic having a user interface for inputting wind direction and speed information. [Background technology]

[0003] Ballistic calculators, whether built into the rangefinder or accessed through a network-connected device, require the user to manually input wind direction (and sometimes wind speed) or use a second device to measure wind direction and / or speed. Manual input of wind direction and / or speed into a viewing optic is very tedious and highly inaccurate, especially as wind direction and speed are important factors in calculating ballistics. User interfaces vary from device to device, and the appropriate screens may be buried deep within menu selections. Equally important is the timeliness of inputting this information before the wind changes or the target moves.

[0004] Typically, wind direction is observed and / or measured at a first device and then manually entered into the ballistic calculator. For example, consider a hunter attempting to shoot a deer 750 yards away. The hunter obtains a ballistic solution based on a wind speed of 8 mph at 75° to the hunter, and this data was previously entered. Just before pulling the trigger, the wind changes and is now at 130° to the hunter. If the hunter had to manually enter the wind direction by cycling through multiple menus to update the wind information, the hunter would not be able to make the shot.

[0005] Wind direction is also typically entered relative to the current target and must be updated if the shot direction changes. For example, consider a hunter who is aiming at a deer north of his location and enters wind information from the wind blowing from the east. The hunter then aims at a deer he wants to shoot that is due east of his location. The hunter must update the wind direction because the wind is now coming from behind him instead of to the right. This can be problematic as well due to the time and stress involved in the situation the hunter faces.

[0006] Wind direction is only one factor that ballistic calculators use to determine a bullet's trajectory. Additional environmental factors such as atmospheric pressure, humidity, and temperature also affect a bullet's trajectory. Often, users must carry multiple instruments to capture the environmental data that is hoped to be input into the ballistic calculator to generate a more complete trajectory.

[0007] The same scenario can also be applied to competitive shooting, where each shooter must time his shots and make quick adjustments. Before shooting, the shooter quickly inputs all environmental parameters. Usually, wind direction and speed are the only parameters that are not directly input into the ballistic calculator. Therefore, the shooter must quickly input these and prepare to shoot the target. If the wind direction or speed changes just before shooting, the shooter must input the new wind data into the ballistic calculator. The same applies if the shooter participates in a target with a different direction than the previous target.

[0008] For an archer to understand the wind direction, the display must be highly intuitive. Currently, it is common to report wind direction and target direction as compass directions, e.g., 270° wind is wind blowing from west to east. To intuitively know if the wind is entered correctly, the archer must know that the wind direction is north. Also, it can be difficult to quickly know which direction the compass direction is, e.g., 237°.

[0009] Another common method of inputting wind direction is the clock method, where the wind input is divided into 12 segments and thought of like a clock. For example, wind at 3 o'clock is from the shooter's right. While this is an intuitive way of understanding wind direction relative to the shooter, it is only valid for the current shooting conditions and does not translate to an intuitive understanding of other wind directions that may occur in future shots.

[0010] Below is an example of the steps required to input wind information: (1) Determining wind direction (absolute heading) and speed, for example, using one or more devices external to the ballistic computer; (2) Press and hold a designated button for a preprogrammed time to display the desired menu; (3) Press a designated button to navigate through the menu options to further menus where the user can modify the wind direction; (4) Press a designated button to change wind direction (absolute heading), for example, using hour values ​​from 1 o'clock to 12 o'clock on a standard clock, where each hour represents a 30-degree segment of a 360-degree circle; (5) Press the designated button to go to the menu where you can change the air speed; (6) Entering the wind speed by pressing a designated button, e.g., by pressing a designated increase or decrease button until the displayed value is the desired wind speed; (7) Press and hold a designated button for a preprogrammed amount of time to exit the menu. (8) Press the specified button to measure the distance.

[0011] As outlined above, ballistic calculators require the user to navigate multiple menus to input wind direction and speed, and / or use multiple instruments to obtain the information necessary to complete the ballistic calculation.

These sensors are operably coupled to the ballistic calculator such that the ballistic calculator can utilize data captured by one or more sensors in determining the trajectory of the bullet.

[0075] In a further embodiment, the one or more sensors are operably coupled to a memory device that stores data captured by the one or more sensors.

[0076] In a further embodiment, the one or more sensors are operatively coupled to a user interface such that data captured by the one or more sensors is displayable.

[0077] In one embodiment, ballistic parameters related to temperature, atmospheric pressure, humidity, altitude, and ambient light conditions are sensed by a thermometer, barometer, hygrometer, altimeter, and illuminometer, respectively, and the sensed digital measurements from each of these digital ballistic parameter instruments are configured to be transmitted (e.g., in real time) to a processor having a ballistic computer program.

[0078] In one embodiment, the observation optics can have an inertial navigation unit, including but not limited to a three-axis compass, a three-axis accelerometer, and a three-axis gyroscope. In other embodiments, the three-axis compass, the three-axis accelerometer, and the three-axis gyroscope can be integrated into the observation optics 100 / 100' as individual components with appropriate software, rather than being integrated into the observation optics 100 / 100' as an integrated unit. In yet other embodiments, the gyroscope can be omitted. Additionally, other tilt sensors can be used in place of the acceleration sensor. Examples of other tilt sensors include an electrolyte level tilt sensor, an optical bubble tilt sensor, a capacitive bubble tilt sensor, a pendulum mechanism, a rotary optical encoder, a rotary electrical resistive encoder, a Hall effect device, and a ceramic capacitive tilt sensor.

[0079] In one embodiment, the observation optics 100 / 100' includes a processor or computing device that includes a ballistic calculator or ballistic computer program that a user can access using one or more buttons operably connected to the ballistic calculator to determine the trajectory of a projectile based on one or more factors, such as the weight of the projectile, the distance to the target, and environmental factors (e.g., wind speed and direction).

[0080] In one embodiment, the ballistic calculator calculates a ballistic solution using two variables obtained from the orientation sensor: (1) wind direction, and (2) direction to the target. In one embodiment, the direction to the target is captured at the same time that the range to the target is determined by the ranging system. In one embodiment, the direction to the target is calculated relative to the captured wind direction.

[0081] In one embodiment, a processor including a ballistic calculation program may be configured to process, but is not limited to, information regarding external field conditions (e.g., date, time, temperature, relative humidity, target image resolution, atmospheric pressure, wind speed, wind direction, hemisphere, latitude, longitude, altitude), firearm information (e.g., barrel twist rate and direction, internal barrel diameter, internal barrel bore, and barrel length), projectile information (e.g., projectile weight, projectile diameter, projectile bore, projectile sectional density, one or more projectile ballistic coefficients (as used herein, "ballistic coefficients" refers to the ballistic coefficients of the American Bulletin, by William Davis, March 1989, which is incorporated herein by reference). The ballistic data may include one or more aspects of ballistic data, including the following: (i) the projectile configuration, the shot type, the shot volume, the shot potential power, the primer, and the muzzle velocity of the cartridge; (ii) the type of reticle, the magnification, the primary, secondary, or fixed functional face, the distance between the target collection device and the barrel, the positional relationship between the target collection device and the barrel, the distance at which the telescopic sight was zeroed using a particular firearm and cartridge; (iii) information about the shooter (e.g., the shooter's visual acuity, visual idiosyncrasies, heart rate and rhythm, respiratory rate, blood oxygen saturation, muscle activity, brainwave activity, the number and position coordinates of observers assisting the shooter); and (iv) the relationship of the shooter to the target (e.g., the distance between the shooter and the target, the speed and direction of movement of the target relative to the shooter, or the position of the shooter relative to the target (e.g., if the shooter is in a moving vehicle), the direction from true north, and the angle of the rifle barrel relative to a line perpendicular to gravity).

[0082] In one embodiment, the viewing optics 100, and in particular the ballistic calculator, have at least two user selectable modes, including but not limited to a "Ballistic" mode. Ballistic calculations are extremely important to shooters at distances in excess of 500 yards. At these distances, the effects of gravity, bullet characteristics, gun characteristics, temperature, atmospheric pressure, relative humidity, wind direction, and wind speed have a significant effect on the overall trajectory of a bullet.

[0083] In one embodiment, the processor can also provide wind, temperature and other environmental field data from a remote sensing device. In one embodiment, the remote sensing device can be wirelessly linked to the processor. The processor can determine one or more ballistic parameters from data collected from the range finder and inclinometer and the remote sensing device, and then calculate the required point of aim (POA) to point of impact (POI) adjustments based on these ballistic parameters. The processor can then transmit data signals to the display representative of the vertical and windage adjustments required or desired for the POA to POI adjustments. As described herein, such communication of signals between the processor and the display can be accomplished by either a wired or wireless link.

[0084] In one embodiment, the observation optics 100 / 100' further includes a memory device (not shown). The memory device may be embedded so as to be housed within the observation optics 100 / 100', or may be external to the observation optics 100 / 100' and in communication (either wired or wireless) with the observation optics 100 / 100'. In such an embodiment, the memory device is operatively connected to both the orientation sensor and the ballistic calculator. In one embodiment, the connection with the orientation sensor and / or ballistic calculator may be wired or may utilize wireless communication techniques. In an embodiment having a memory device, the captured wind direction data may be stored in the memory device and accessible to the ballistic calculator.

[0085] Additionally, with the wind direction captured and stored, the user can continually range targets and obtain wind-compensated ballistic solutions, unless the wind direction or speed changes. However, if the wind is steady, the user only needs to range new targets, providing a simple and efficient process for obtaining wind-compensated ballistic solutions.

[0086] In one embodiment, the viewing optics 100 / 100' include a display. The display may be integrated into the sights of the viewing optics 100 / 100' or may be visible on the exterior of the viewing optics 100 / 100'. In further embodiments, the display may be a separate component from and in communication with the viewing optics 100 / 100', such as a device such as a computer, tablet, cell phone, television, etc. The display is configured to display a variety of information including menu options and ballistic data.

[0087] In one embodiment, the display is configured to display the distance to the target. For example, if the viewing optics 100 / 100' include a laser range finder function, the ballistic computer calculates the distance to the target, as described above and with particular reference to the measure button 2. When the measure button 2 is activated (e.g., pressed), the viewing optics 100 / 100' emits a laser beam, which the user directs toward the desired target. The laser beam reflects off the target and returns to the viewing optics 100 / 100'. The ballistic computer calculates the distance from the viewing optics 100 / 100' to the target based on the signal strength of the reflected beam and the time it takes to receive it.

[0088] In a further embodiment, the viewing optics 100 / 100'includes an inclinometer. In such an embodiment, the display may be configured to display the elevation angle of the target.

[0089] It will be understood that the specific shape, arrangement and physical design of buttons 1-5 described herein may vary, provided that buttons 1-5 are operably connected to the on-board range finder system to enable functionality.

[0090] In one embodiment, the viewing optics 100 / 100' assist the user in compensating for wind direction and speed.

[0091] As mentioned above, wind direction and speed have a large effect on the trajectory of a bullet. Additionally, atmospheric pressure, ambient temperature, and relative humidity also affect the trajectory. Although the distance from the shooter to the target is often the key factor, each of the above environmental factors has a significant effect on the trajectory. The table below shows the effect of a 10% change in some of these parameters. Table 1 TIFF2025511248000002.tif93155

[0092] In fact, Table 1 shows that varying the distance to the target has the greatest effect on ballistic trajectory, followed by atmospheric pressure and wind speed. For example, when using a firearm with a certain ammunition and shooting a consistent target at 1,000 yards, wind direction and speed can significantly affect the distance a bullet travels, and can affect the distance by up to 80 inches or more. As a specific example, the effect of wind on bullet trajectory for a user shooting a 1,000 yard target using a Winchester .308 rifle, Hornedy ELD-X 178 grain bullet, rifle zeroed at 100 yards, muzzle velocity of 2,650 feet per second, atmospheric pressure of 29.08 inches Hg, temperature of 70° F, and relative humidity of 60% is as follows: (1) Wind direction is 0° relative to the target, 0 miles per hour (mph) - the bullet will drop approximately 357 inches and travel approximately 6 inches to the left. (2) Wind direction 90° to the target, 10 mph - the bullet will travel approximately 357 inches down and 75 inches to the left. (3) Wind direction is 40° to the target, 10 mph - the bullet will travel approximately 359 inches down and 47 inches to the left.

[0093] The above scenarios show how a 10 mph wind coming from different directions can affect the trajectory of a bullet. You can see that the longer the distance to the target, the greater the effect of wind on the trajectory of the bullet.

[0094] FIG. 3 illustrates an exemplary method 300 for inputting wind speed coming from a direction into the observation optics in accordance with an embodiment of the present disclosure.

[0095] First, the user selects a mode that allows the wind direction to be captured using the orientation sensor. In one embodiment, accessing the mode 305 includes pressing and holding a button (or pressing a specific sequence of buttons) to enter a mode that allows the wind direction to be captured using the orientation sensor. In one embodiment, the specific button is a wind orientation capture button 3 as described herein. In one embodiment, pressing and holding a designated button 305 includes pressing and holding a designated button for a designated time, for example, 3 to 6 seconds, more preferably 3 to 5 seconds. Note that step 305 may not be necessary if the wind capture mode is already accessed.

[0096] Next, the observation optics are oriented in the direction from which the wind is blowing (step 310).

[0097] Once the viewing optics are in the appropriate mode and properly oriented, the user presses a button to capture the wind direction (step 315). In one embodiment, the button may be the same as the designated button of step 305. In a further embodiment, the button is a wind direction capture button 3 as described herein. In one embodiment, pressing the button to capture the wind direction includes pressing and holding the button for a designated time period that is typically less than the designated time period of step 305, such as less than 2 seconds, or more preferably less than 1 second.

[0098] In one embodiment, pressing a button to capture wind direction 315 further includes automatically inputting the wind direction data into a ballistic calculator and / or memory device onboard the observation optics.

[0099] Step 320 is pressing a button or buttons to manipulate the wind speed value. In one embodiment, the viewing optics includes two buttons, such as the first and second selection buttons 4, 5 described above, one of which helps the user increase the wind speed value and the other of which helps the user decrease the wind speed value.

[0100] Next, the ranging system is activated to obtain a range measurement (step 325). Furthermore, when the ranging system is activated, the orientation sensor captures the direction to the target. In one embodiment, the step of obtaining the range measurement includes aiming the observation optics at the target and pressing a predetermined button to perform the range measurement. At the same time, the orientation sensor determines the direction to the target.

[0101] In one embodiment, the designated button is a measurement button 2 described herein. In one embodiment, pressing the designated button 325 includes, for example, pressing and holding the designated button for a period of time necessary to obtain a consistent measurement.

[0102] Optionally, in a final step 330 to exit the input mode, a designated button is pressed and held (or a series of buttons are pressed). In one embodiment, the designated button is Menu Button 1 as described herein. In one embodiment, pressing and holding the designated button 330 includes pressing and holding the designated button 330 for a designated time, for example, 3 to 6 seconds, or preferably 3 to 5 seconds. Although it is useful to exit the ballistic calculator mode after setting each of the parameters described above, it is generally not necessary to do so in order to use the observation optics.

[0103] In further embodiments, the method further includes pressing (and in some cases holding) a predetermined button to enter / exit different modes to capture and / or display information obtained from additional sensors, including but not limited to an anemometer, air pressure sensor, humidity sensor, and temperature sensor. Steps related to capturing and / or displaying data obtained from the anemometer, air pressure sensor, humidity sensor, and temperature sensor may be completed either before steps 305, 320, 325, or 330, or after step 330. Information obtained from one or more of the sensors may be stored in a memory device.

[0104] In another embodiment, the method includes using the ballistic calculator to automatically capture data from one or more of an anemometer, an atmospheric pressure sensor, a humidity sensor, and a temperature sensor. When data from the anemometer, the atmospheric pressure sensor, the humidity sensor, and the temperature sensor is automatically captured, the data may be captured simultaneously with any of steps 305-330, or may be captured before or after any of steps 305-330.

[0105] In one embodiment, the present disclosure relates to a user interface for inputting wind direction and / or speed data. In one embodiment, the present disclosure relates to a viewing optical instrument having a user interface for inputting wind direction and / or speed data. In one embodiment, the user interface can include a number of input and / or output devices, such as buttons, keys, knobs, touch screens, displays, etc.

[0106] FIG. 4 illustrates an exemplary wind direction display portion of a user interface for a viewing optics. In particular, FIG. 4 illustrates a wind direction display portion of a user interface. The user interface may include additional information that a user desires to be displayed, such as, for example, remaining battery power, network connection information (e.g., wireless connection strength, network connection name, Bluetooth® connection status), distance to target, user profile information, wind speed, absolute heading, ballistic information, etc. Such a wind direction display may be provided on a viewing optics that includes a ballistic calculator, or may be provided on a device such as a computer, smartphone, or other connected device.

[0107] As shown in Figure 4, the wind direction indicator includes a circle or broken circle. In the illustrated embodiment, the circle or broken circle is a broken circle. With reference to the orientation of Figure 4, the broken circle includes gaps at approximately 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock. The gaps at 3 o'clock and 9 o'clock are shown to be larger than the gaps at 12 o'clock and 6 o'clock. More specifically, in the illustrated embodiment, the circle or interrupted circle is an interrupted circle having gaps at approximately 0°, 90°, 180° and 270°, the 0° and 180° gaps having a degree scale of 2.5°, or 5°, or 7.5° to 10°, or 12.5°, or 15°, or 17.5°, or 20°, and the 90° and 270° gaps having a degree scale of 20°, or 25°, or 30°, or 35°, or 40° to 45°, or 50°, or 55°, or 60°, or 65°. In further embodiments, the gaps may all be of equal size or may be independently of different sizes.

[0108] The additional information is shown inside the circle or broken circle. By containing the additional information within the circle or broken circle, the information remains organized and uncluttered for the user.

[0109] The circle or broken circle is surrounded by a plurality of independently visible marks. In the illustrated embodiment, the independently visible marks are triangles. However, in further embodiments, the independently visible marks may be any shape. In one embodiment, the independently visible marks may generally indicate a direction toward the center of the circle or broken circle.

[0110] As shown in FIG. 4, the visible marks are evenly spaced around the circle or broken circle, generally at positions corresponding to the numbers on the clock. That is, in the illustrated embodiment, the visible marks are arranged at 30° increments around the circle or broken circle, with one mark occurring at each of 0°, 30°, 60°, 90°, 120°, 150°, 180°, 210°, 240°, 270°, 300°, and 330° around the circle or broken circle. In another embodiment, the marks can be arranged at different positions around the circle or broken circle, for example, more or less frequently, or at various positions. In yet another embodiment, marks of different shapes may be provided to correspond to various positions. In yet another embodiment, the marks may be part of the circle or broken circle itself.

[0111] Using an input device, such as a button on a user interface, a user can use the wind direction indicator to identify and select a wind direction. In one embodiment, actuation of the input device, such as a button, causes at least one of the visible marks to become more visible than the other marks. Further actuation of the input device either (1) causes a subsequent mark to become more visible than the other marks and the previously visible mark to become less visible, or (2) causes a subsequent mark to become as visible as the at least one visible mark.

[0112] As a non-limiting example, the process for inputting wind direction using the user interface is as follows: When the user presses the wind direction button, the 0° mark is illuminated. When the button is pressed a second time, the 30° mark is illuminated, indicating a 15° wind direction to the user. When the button is pressed a third time, the 0° mark is turned off, indicating a 30° wind direction to the user. This process continues around a circle or broken circle, with one mark being illuminated or highlighted or more visible to indicate the relative wind direction to the user at that location, and two adjacent marks being illuminated or highlighted or more visible to indicate the relative wind direction to the user at locations between more than two marks.

[0113] By way of further illustration, Figure 5 shows an exemplary user interface for inputting wind direction. Activating an input device, such as a button or tap on a touch screen, adjusts the wind direction one step.

[0114] In one illustrated embodiment, actuation of the input device changes the wind direction symbol in a clockwise direction (i.e., from 0° to 360°). In one embodiment, the input device changes the wind direction symbol in a counterclockwise direction. Additionally, in one embodiment, two input devices may be provided, one for clockwise movement and one for counterclockwise movement.

[0115] As also shown in FIG. 5, the exemplary input device includes a menu button for accessing various menus, a measure button for entering a mode for changing wind speed, a wind direction capture button for entering a mode for changing wind direction, and two value adjustment buttons, which in the illustrated embodiment are left and right arrows, respectively.

[0116] To explain the method of adjusting the wind direction depicted in FIG. 5 with particular reference, the user adjusts the wind direction as follows: First, the user presses and holds the wind direction capture button to enter wind direction capture mode. In wind direction capture mode, the additional information in a circle or broken circle is replaced with a caption indicating that the wind direction capture mode has been accessed. The user then presses any adjustment button as necessary until the appropriate relative wind direction is displayed.

[0117] In one embodiment, the user presses the right adjustment button a first time to change the relative air direction from 30° to 45°. Pressing the right adjustment button a second time moves the relative air direction from 45° to 60°.

[0118] In one embodiment, the markings are described as being illuminated, in other embodiments the markings may be highlighted in other ways, such as changing color, blinking, changing shape, or otherwise enhancing visibility.

[0119] In one embodiment, the exemplary input device is shown as being on a panel directly adjacent to the user interface, in further embodiments, the input device is located elsewhere relative to the user interface, such as below, above, or otherwise a distance away from the user interface.

[0120] In one embodiment, the user interface includes a wind speed display.

[0121] 6A-6B also show an exemplary input device as shown and described in the accompanying figures. In particular, the exemplary input device includes a menu button for accessing various menus, a measure button for entering a mode for changing wind speed, a wind direction capture button for entering a mode for changing wind direction, and two value adjustment buttons, which in the illustrated embodiment are left and right arrows, respectively.

[0122] With particular reference to the method of adjusting the wind speed depicted in Figures 6A-6B, the user adjusts the wind speed as follows: First, the user presses and holds the measure button to enter the wind speed measurement mode. In the wind speed capture mode, the circle or broken circle and the mark are removed from view indicating that the wind speed capture mode has been accessed, although the circle or broken circle additional information remains displayed. The user then presses any adjustment button as desired until the appropriate wind speed is displayed. In one embodiment, the user can press the left adjustment button three times to decrease the wind speed from 5 mph to 2 mph.

[0123] In one embodiment, the exemplary input device is shown as being on a panel directly adjacent to the user interface, in further embodiments, the input device is located elsewhere relative to the user interface, such as below, above, or otherwise a distance away from the user interface.

[0124] In one embodiment, an input device must be actuated to enter the wind direction capture mode and / or wind direction capture mode. In one embodiment, a single "menu" input device is provided to allow a user to cycle through different menu and mode options. This single input device is in addition to and separate from at least one input device that changes the mark and wind speed display. In one embodiment, the same input device or devices that change the wind direction mark and wind speed display are used to change menu and mode options.

[0125] A user interface, according to one embodiment of the present disclosure, is used to receive and display data from the ballistic calculator. The ballistic calculator may be part of a viewing optic, such as binoculars, a range finder, a scope, or other such device. In such an embodiment, the viewing optic may further include a battery, a control module, a data entry device, a processor, memory, and / or an anemometer, a compass, a thermometer, and / or one or more sensors used to sense various environmental conditions or characteristics associated with the viewing optic. Such viewing optics may also include any type of digital storage mechanism or memory. The digital storage mechanism or memory may be inserted into the ballistic calculator and configured to store information generated by the ballistic calculator.

[0126] In one embodiment, the digital storage mechanism or memory may be accessed remotely by the viewing optics via a wired or wireless connection.

In such embodiments, the digital storage or memory may be located on the viewing optic and / or housed remotely. The viewing optic and the ballistic calculator communicate via a wired or wireless connection.
