Patent Application

The present invention relates to the field of projectile weapons and targeting systems and methods.
Projectile-firing weapons have been in use at least since the end of the upper Paleolithic period, when archery (the “bow and arrow”) had been invented. A bow is a projectile-firing weapon in which at least one flexible member creates tension in an attached line, which line may be drawn, flexing the member, and then released to propel a projectile known as an arrow by the elastic rebound of the member and line. In modern warfare, firearms and ballistic missiles use propellants to accelerate projectiles at much higher speeds and to strike distant targets, some of which may be difficult, or even impossible, to view with the naked eye. To capitalize on those capabilities and help direct such projectiles to their distant targets, targeting science has been developed.
A wide variety of aiming devices, known as “sights,” have been developed, and allow a user to aim a projectile weapon at a target using the user's vision to align the two. For example, a rifle-mounted telescopic sight (a.k.a. “scope”) allows a marksman to target distant subjects, typically including the use of optic lenses and a superimposed reticle in the form of crosshairs meeting at a point associated with a point of impact of the projectile (“Impact Point”). Using scopes mounted on high-powered, long-range rifles, highly skilled military and police marksmen, known as snipers, may successfully target and hit subjects at an effective range above 1,000 meters.
However, environmental and user factors can greatly impact the accuracy of rifle and other projectile weapon fire, especially in the instance of ballistic projectiles from handheld weapons. These factors include, but are not limited to: 1) air density, 2) wind velocity, 3) humidity, 4) visibility, 5) air quality, 6) elevation from subject, 7) ambient temperature, 8) hand and body tremor of the user, 9) shake and misalignment due to trigger pull, 10) flinching due to shot anticipation or environmental activity, 11) movement due to breathing, 12) movement due to heartbeat, 13) errant movements, 14) eye shift not addressed by the sight (parallax effect), 15) environmental structural changes or nudges (e.g., sand bag or tripod sinking, nudge from fellow soldier), 16) changes or states of change of any of the above factors, and 17) subject or other more general environmental movement. At longer firing ranges, the impact of these environmental and user factors, and resulting targeting inaccuracy, can be exponentially amplified. But greater ranges are beneficial, because they allow a sniper to maintain a safe distance from enemy forces and remain undetected. If snipers are located, critical missions may fail, and, in military campaigns, snipers may be captured and assassinated.
Advanced reflecting and collimating sights, such as “red dot” sights, are designed to provide rapid acquisition and targeting with both eyes open and observing the entire environment as well as sight components. Such sights may also reduce or substantially eliminate the parallax effect that occurs when the shooter shifts eye position relative to the reticle of a scope or iron sights.
New targeting systems, hardware and techniques are provided. The disclosed systems enable a sniper to plan measures with extreme precision within an environment, evaluate their effectiveness, and execute them extremely rapidly once satisfied. In some aspects of the invention, a user of a targeting system may create, set, adjust and execute Impact Point(s) and Impact Point indicator(s), each corresponding with the projected point of impact of a projectile on a target within a target environment. In other aspects, the system may counteract and otherwise adjust for certain ballistic, viewing perspective and projectile accuracy-affecting factors, in a sighting display and in a projectile firing mechanism, while maintaining the influence of others to allow for rapid targeting adjustment, by adjusting their vertical, horizontal, z-axis and rotational positions in real time, to maintain an environmental view, impact point and impact point indicator despite those factors. The system is unobtrusive, allowing the user to engage ordinary targeting activity.
In some embodiments, an auxiliary probe is first launched and deployed at a target. Extremely precise, deliberate targeting for future projectiles, weapons or non-lethal measures is then made relative to the position and orientation of the probe.
In one embodiment, the invention enables a sniper to, in effect, take a projected, trial shot at a subject within an environment, evaluate its effectiveness, and then execute it only if satisfied. Prior to this invention, shots needed to either succeed or fail, with one, actual take—often with disastrous, irreversible consequences.
In other aspects of the invention, the system may execute multiple impact points together or in rapid succession, which impact points may surround, lead, cover or otherwise have a diverse distribution about a targeting subject and/or projected target subject path, based on movement and other environmental factors.
These aspects of the present invention may be applied to a wide variety of other technological fields, including, but not limited to, shipment and inventory tracking and photography.
In still other aspects, a new form of projectile, which implements lift that increases at lower speeds to counteract gravitational drop, while maintaining rifle-driven spiraling, is provided.
Within this specification of aspects of the invention, including its embedded definitions, plural and singular constructions may be treated interchangeably unless otherwise indicated in context. Indicated gender pronouns may be treated interchangeably with neutral or other gender pronouns. The exact embodiments disclosed in this specification for carrying out aspects of the invention are not exhaustive of all such embodiments within the scope of the invention. Where applicable, other known methods of carrying out tasks and mechanics of the invention may also, or alternatively, be used, and should be considered incorporated into the specification.
The rifle, scope, system and some environmental elements in this illustration will be repeated in additional figures, below, to illustrate the operation of aspects of the invention over time. A rifle 101 is trained/aimed in the general area of a subject (in this instance, the driver of a truck) 103 on a distant roadway 105. A telescopic rifle sight (“scope”) 107 magnifies the subject 103 and some of the surrounding area, within it's viewing portal 109, which may be enclosed by a cylindrical housing 111 and include a collimating lens assembly and/or electronic viewfinder display features, which may themselves be collimated and variable, and cover or augment the entire field of view of the viewing portal 109, and will be discussed in greater detail below with reference to this and other figures. The electronic viewfinder display aspects of the present invention are capable of creating variably-placed, -sized and -shaped images, including but not limited to virtual images, of a reticle and/or potential point-of-impact (or “impact point”) indicating dots and other indicator aspects, which images and/or virtual images may be instantaneously placed, moved, morphed, colored, provided with active lighting (“glow”) or otherwise modified. In any event, a more standard, physical reticle with crosshairs 113 may also be included, and may or may not itself be reflecting or collimated to ensure or correct for proper alignment and parallax in target sighting. Crosshairs 113 converge at a point initially generally corresponding with a point of impact of a projectile to be fired from the rifle, but the convergence point may require or be subject to adjustment to account for windage, range, angle/drop vector and other ballistic and/or environmental factors. An electronically actuated variable mounting 115 permits the adjustment of the horizontal and vertical position of the viewing portal 109 and/or the crosshairs 113, and may also allow adjustment of the rotational angle of the scope as may be required for it to remain viewing at least part of a selected target, as will be discussed in greater detail later in this application with respect to certain embodiments, but this aspect need not be included in all embodiments of the invention. Alternatively, a partially or entirely artificial or transposed image viewfinder or other display, such as but not limited to a light-emitting diode (LED or OLED) or other electronic/photonic display aspect(s), may be used to create images in the viewing portal corresponding with a view of at least part of the target environment, in which instance variably-angled sensors or cameras may also be used in place of scope lenses and variable mounting 115 may not be required.
A system including control system unit 117 (which, as discussed with reference to
The stock or barrel of rifle 101 may be rested on sandbags 129, a tripod, or other stabilizing prop, and/or the shooter's arm (not pictured), for resting the rifle and enhancing physical stability. A bolt action 131 and optional manual reloading bolt lever 133 may be used for chambering cartridges and actuating an angle-variable firing mechanism (not pictured in this figure), including a firing pin and barrel, in accordance with aspects of the present invention, an example embodiment of which is provided with respect to
The following is a discussion of some of the ways in which the system may be used by a shooter in a staged, deliberate and perfecting manner to separately acquire and fire upon a targeting subject with high precision, while eliminating or reducing many external factors that otherwise would threaten accuracy. First, as shown in
According to some embodiments of the present invention, in creating and/or maintaining the new impact point and new impact point indicator, additional aspects of which will be discussed in greater detail below, a system, including but not limited to the control system unit 217, may account for and apply ballistic and other projectile path correction functions to correct for or address any or all of the factors affecting or potentially affecting the accuracy of the new impact point indicator at indicating a point of impact of a projectile on a target, if and when it is fired from the rifle. The potential influence of such factors may be sensed by sensors (not pictured) which feed data to the system, such as, but not limited to, wind velocity, altitude, shot angle (and corresponding gravity vectors causing projectile drop over the range of a shot fired), barometric pressure, air temperature, humidity, environmental nudging or hand shake—such that position correction and/or intercept algorithms and/or functions may be applied to servo/motors, solenoids or other actuators controlling both the training angle of the firing mechanism/barrel and the scope, as necessary to maintain firing capability on an impact point and maintain the New Impact Point indicator and target within the field of view of the scope. However, preferably, at this stage (new impact point created but not yet set), human and other environmental movement variables are allowed to continue to move the scope, reticle and new impact point indicator while the system adjusts only the firing mechanism and barrel angle to maintain a set point of impact at the location corresponding with the new impact point, as it may move with the user's hand or other aiming movements. This preferred embodiment will be further illustrated, and discussed in greater detail, with respect to later figures.
To aid the system in counteracting gravity vectors causing projectile drop over the range of a shot fired, a specialized form of projectile may also be used, which eliminates or greatly reduces the increasing rate of bullet drop over the flight path of most ballistic projectiles unpowered during some part of flight. Specifically, such a projectile includes lift-creating elements, at least one of which creates a drafting effect on another element, blocking or reducing some of the lift-producing airflow on that another element. As the projectile experiences drag in flight, and reduces its speed, at later points in its flight, the influence of gravity is more greatly offset in such a projectile, by increased airflow and lift on that another element. To maintain fixed, as opposed to spinning, airflow elements, an internal gyro aspect, which may spin within a housing including such airflow elements, may be included, which gyro may be caused to spin by a rifling or other spin-inducing element of the firing mechanism and/or projectile, increasing the projectile's stability. For rifling to induce such spin, access port(s) and/or access grooves in the housing may be included, allowing rifling to engage the gyro unit, or some tab or aspect thereof, to cause it to spin, while straight-line leveling grooves engage the lift-producing elements, or another housing element, to produce rotationally stabilized, or level flight in the housing.
Turning back to the embodiment illustrated in
Assuming that the sniper has successfully created a new impact point and indicator on or near the subject, as desired, using the steps and adjustment process discussed immediately above, the figures below address further aspects of the present invention.
Accordingly, the rifle scope generally has been allowed to shift and change its angle with the user or environmental movement discussed above, and now points, along with the reticle, downward and to the left of the subject, rather than directly at it. Nonetheless, due to the active, instantaneous maintenance of the set new impact point and its indicator appearing at the location of the subject, counteracting the present and/or future projected influence(s) of accuracy-affecting factors on the indicator and firing mechanism, a sniper firing the rifle at any time after setting a new impact point and indicator will result in firing a projectile that will accurately impact the subject location, despite those otherwise accuracy-impacting factors. By allowing rifle movement to continue moving the scope, and altering the view in the viewing portal, at the same time as maintaining the new impact point, indicator, and firing mechanism, however, the sniper is able to continue scanning and evaluating more of the environment, and may set new impact points in new locations, selecting each for a rapid, simultaneous or otherwise well-timed execution. This embodiment is preferred due to this versatility with high accuracy. It is also preferred because it enables a sniper to, in effect, take a projected, trial shot at a subject within an environment, evaluate its effectiveness, and then execute it only if satisfied. Prior to this invention, shots needed to either succeed or fail, with one, actual take often with undesirable, irreversible consequences.
In other embodiments, the scope and/or reticle itself may continue to indicate the point of impact by moving, along with the servo/motor actuated barrel, to counteract any and all user and environmental factors impacting accuracy—rather than remain fixed with respect to, and moved by, some user or environmental factors, as in the preferred embodiment above. In such embodiments, by selecting a new impact point, the crosshairs themselves, or some part thereof, may change shape, color, active lighting, or other indicating characteristics to signify that such a new impact point has been created. Such indicating characteristics, but of a different nature, may separately indicate new, additional Impact Points and the setting or priority status(es) thereof, and additional reticles may also be added, to address those new impact points, in which case the scope may follow (centered on) the latest new impact point or highest priority new impact point (“N.I.P.”) with a corresponding reticle, instead of or in addition to another impact point indicator or component thereof, such as those discussed above, unless and until the setting of another impact point has begun.
Assuming that the sniper has not yet executed a command to the system (e.g., by full trigger pull) to execute the impact point that was set, and shown by the impact point indicator 335 and 337, the user may, of course, cancel the impact point or tweak its location, using the user controls as discussed above. However, the user may also choose to set an additional new impact point and indicator, aspects of which will be discussed in greater detail with reference to
If a sniper then chooses to execute one or both impact points, the system would first cause the impact point selected for first execution (“highest priority”) to be hit with a projectile, by actuating the firing mechanism as described above for maintaining aim (including offsetting all environmental and user accuracy-impacting factors) and firing upon (“executing”) an impact point. If the user then commanded the system to execute the second impact point, the system would then actuate the firing mechanism to cause a projectile to hit the second impact point, e.g., by repositioning the barrel (aiming it) to do so, accounting for all factors impacting accuracy. In some aspects of the present invention, the system may rapidly execute firing upon each impact point without pausing to allow the rifle to settle after recoil, and further counteract the impact of recoil as another accuracy-impacting factor. But in other aspects, the system may pause to allow such settling, or, at least, part of such settling, to retain firing capability within the range of possible firing mechanism adjustments. Different modes may be available to permit the user to fire upon all impact points set, or to “double-tap” or otherwise produce a close grouping, coverage of possible locations of a target, or other patterns of multiple shots with an automatic rifle on or about an impact point or series of impact points, which actions may be executed upon one command (e.g., one trigger pull). But serial execution (one impact point per trigger pull or other command from highest to lowest priority—which may be rearranged by the user) after recoil settling and determining that the impact point is still within the viewing portal, which may correspond with being executable by the system, may be preferred for some sniping applications, and may also be used in executing such patterns.
The targeting methods and systems set forth in this application may apply equally to a wide variety of other pointing, aiming, targeting and executing activities, including, but not limited to, cameras and electronic tagging or data write/re-write activities. For example, shipment tracking systems and high-speed photography systems may create multiple targeting (impact points) for focused activities using the same types of controls and a similar GUI (e.g., photographic viewfinder rather than reticle), but for intercepting a point or area with a tracking (scanning, reading, writing) or photographic activity.
Among other components, the system 500 includes an input/output device 501, a memory device 503, storage media and/or hard disk recorder and/or cloud storage port or connection device 505, and a processor or processors 507. The processor(s) 507 is (are) capable of receiving, interpreting, processing and manipulating signals and executing instructions for further processing and for output, pre-output and/or storage in and outside of the system. The processor(s) 507 may be general or multipurpose, single- or multi-threaded, and may have a single core or several processor cores, including microprocessors. Among other things, the processor is capable of processing signals and instructions for the input/output device 501, analog receiver/storage/converter device 519, and/or analog in/out device 521, to cause a user interface to be provided or modified for use by a user on hardware, such as, but not limited to, physical human hand tracker and other human body part interface controls (e.g., 3-D hand sensor, object emulator, joystick control, sight or scope adjustment dials) and/or a personal computer monitor or terminal monitor with a mouse and keyboard and presentation and input software (as in a GUI), rather than or in addition to electronic/photonic scope or sight aspects, as discussed in reference to other figures in this application.
For example, a “window” presentation user interface aspect may present a user, such as a sniper, with a reticle and/or environmental image, remaining scope readouts or display output, with selectable menu options in a GUI, to select settings for targeting and execution, such as creating, cancelling and adjusting new impact points, or the counteraction or other treatment of factors impacting the accuracy of a firing mechanism, as discussed in greater detail elsewhere in this application.
As another example, such a “window” presentation user interface aspects may present a user with the option to target or gesture with respect to particular locations of visual emulations of a model or photographic subject, based on live feedback, such as imaging and the detected movement of painted or edge/boundary detected targets within a collateral medium or material. As mentioned above, a wide variety of sensors or auxiliary probes may be used to aid in detecting, defining and even imaging targeted objects. As another example, the user interface and hardware may allow a user to manipulate a virtual object that may translate movements into control input matching or related to those movements in real time, and with reference to a live model depicted on a computer monitor and presenting instantaneous information from a radar or sonar or Nuclear Magnetic Resonance Imaging (“MRI”) or X-ray radiographic (e.g., CAT scan) machine, which may allow a user to create an activity or apply physical force or energy to particular areas of a target, in particular series, locations, shapes and sizes or pulses and pulse rates to substantially cut or ionize matter, which size and shape may be given a hardness of edge, tolerance, and strength, all individually controllable by a user, and which may be provided as feedback to the user by acceleration of the virtual object, either by an actuable effigy of the shape, size, position, resistance and weight of the virtual object and its controls, or by tactile stimulus (e.g., ultrasound and/or radiative feedback). A virtual object or other ionizing tool may include a shaped cursor which may be semi-transparent, and may allow the user to plan and view a portrayed path for the planned future ionization or other, for example actual, robotically actuated physical movement, such as surgical lancing or other subject manipulation, before it is actually implemented on a subject (which execution can be done in parts or degrees or completely, with a separate, later command to the system). This manipulation path planning may be done with a cursor or other display, such as a computer monitor, or depiction/control hardware and techniques (e.g., 3-D physical contour, camera array projection, cutting, shipment tracking plan, or manipulation emulation device). In any event, a user may create a path of planned movement, shooting or a shooting series, tracking protected subject location or path intercept or other activity or other manipulation by programming such a path and/or by first executing the path in virtual or real space and, optionally, reviewing a depicted path based on that execution, and, if satisfied with the characteristics of the movement(s) of the executed path (e.g., direction(s), length(s), instance(s), location(s), coverage(s), breadth(s), pressure(s), actual or real tissue reaction(s), size(s) of lancing or projected lancing, or blunt instrument trial or projection of where lancing or other actuation will take place), all of which characteristics may be displayed numerically or graphically as an attribute of a depicted path in a display as a “Planned Path,” representation, the user may then choose to have the path executed. Optionally, before choosing to execute the path, the user may choose to save a file composed and capable of executing the characteristics of the movement on the system. Also optionally, the user may elect to modify individual, several or all characteristics of the path over any part of the path's progression (for example, by creating or manipulating segmentation tools such as anchor points along the path), again may choose to save such a file comprised of such information, and again may choose separately to execute the path, which may be executed at different speeds along the path or even with a graduated and/or matched acceleration device, such as a throttle for the path's execution speed (using any possible units/time) which may be stopped at any time during observation of the movement. The system may automatically, or at the user's direction, adjust the path or path segments for unintended hand tremor by smoothing or substituting more graduated curves and movement accelerations along progressions or as to characteristics of the path. The system may automatically, or a user may direct it, to generate reactive or protective radiation in greater, lesser or other amounts that better interfere and protect against ionizing radiation, for protected collateral areas, as well, as another example, based on live feedback concerning the amount of protection actually occurring through interference, as sensed by the system, and/or based on physical models, including refraction models.
The processor(s) 507 is/are capable of processing instructions stored in memory devices 505 and/or 503 (or ROM or RAM), and may communicate via system buses 575. Input/output device 501 is capable of input/output operations for the system, and may include and communicate through numerous input and/or output hardware, and numerous instances thereof, such as, but not limited to, a computer mouse, touch screen, flat panel display, collimating light-augmented scope, and pixel arrays, including a pixel array with differently addressable and separately (or in any progressive or other sub-group) scannable and projectable pixels, system element position sensors and actuators (as in 511, which may be the system described in
Input and output devices may deliver input and receive output by any known means, including, but not limited to, the examples shown with respect to examples 517. The input managed and distributed by the system may be any representational aspect or signal or direct impression captured from any sensed or modeled activity, and may be taken or converted as input through any sensor or carrier means known in the art. In addition, directly carried elements (for example a light stream taken by fiber optics from a view of a scene) may be directly managed, manipulated and distributed in whole or in part to enhance output, and whole ambient light information may be taken by a series of sensors dedicated to angles of detection, or an omnidirectional sensor or series of sensors which record direction as well as the presence of photons sensed and/or recorded, and may exclude the need for lenses (or ignore or re-purpose sensors “out of focal plane” for detecting bokeh information or enhancing resolution as focal lengths and apertures are selected), only later to be analyzed and rendered into focal planes or fields of a user's choice through the system. For example, a series of metallic sensor plates that resonate with or otherwise detect photons propagating in particular directions would also be capable of being recorded with directional information, in addition to other, more ordinary light data recorded by sensors. While this example is illustrative, it is to be understood that any form of electromagnetism, compression wave or other sensed phenomenon may include such sensory, directional and 3D locational information, which may also be made possible by multiple locations and/or angles of sensing, preferably, in a similar or measurably related, if not identical, time frame. The system may condition, select all or part of, alter and/or generate composites from all or part of such direct or analog image transmissions, and may combine them with other forms of image data, such as digital image files, if such direct or data encoded sources are used. Specialized sensors for detecting the presence of interference or resonance of radiation of any type, and imaging the sources or capturing the forces applied based on the known characteristics of waves and electromagnetic radiation in particular, may also be included for input/output devices. Sensors that permit the biangulation or triangulation of light sources, to determine subject and subject environment location and range information, may also be used, and the system may “paint” any part of that subject or environment with electromagnetic, radiative heating, or other markers to ease tracking, targeting, and counteracting environmental/system relative shifts and rotations with the further use of sensors detecting such markings, as discussed in other parts of this application. A direction-indicating beacon may also or alternatively be planted in the surrounding environment to ease these system activities and general system position and subject tracking assessment, including, but not limited to, subject, target and system position projection, in the environment. In this way, impact points may be placed and maintained relative to the subject itself, if marked, or the environment in general.
While the illustrated system example 500 may be helpful to understand the implementation of aspects of the invention, it is to be understood that any form of computer system may be used—for example, a simpler computer system containing a processor for executing instructions and a memory or transmission source. The aspects or features set forth may be implemented with, and in any combination of, digital electronic circuitry, hardware, software, firmware, or in analog or direct (such as light-based or analog electronic or magnetic or direct transmission, without translation and the attendant degradation, of the image medium) circuitry or associational storage and transmission, as occurs in an organic brain of a living animal, any of which may be aided with external detail or aspect enhancing media from external hardware and software, optionally, by networked connection, such as by LAN, WAN or the many connections forming the internet. The system can be embodied in a tangibly-stored computer program, as by a machine-readable medium and propagated signal, for execution by a programmable processor. The method steps of the embodiments of the present invention may be performed by such a programmable processor, executing a program of instructions, operating on input and output, and generating output. A computer program includes instructions for a computer to carry out a particular activity to bring about a particular result, and may be written in any programming language, including compiled and uncompiled and interpreted languages and machine language, and can be deployed in any form, including a complete program, module, component, subroutine, or other suitable routine for a computer program.
A hammer 603 may be included and may be force-biased and caused, upon a shooting execution movement (which may be electronically commanded and/or physically caused) to release stored energy from that force biasing and strike a preferably semi-spherical concave intermediate gear 605 which is physically interfaced with an abutting convex curved, and preferably spherical, striker 607, via gear teeth, such as those shown as 606 and 608. A firing operation embodiment, using the firing mechanism described in this figure, is as follows. When stricken by intermediate gear 605 (itself stricken by hammer 603), striker 607 then, in turn, strikes firing pin 609, which may strike a loaded cartridge (not pictured) held in chamber 611, resulting, for example, in igniting an accelerant and causing a projectile within the cartridge to fire down a rifled barrel 613. Preferably, the magnetic material creating the dipole in spherical striker/gear 607, and shown by groups of negative and positive signs (discussed further, below, and such as those negative and positive signs appearing as, respectively, 610 and 614) is sorted, maintained or reinforced in its dipole position by the striking action—for example, by a heavier positive side of dipole elements.
Any number of physical and electronically mediated, systematically controlled trigger and firing mechanisms may also, or alternatively, be used, to implement various aspects of the present invention. But preferably, a mechanism, which may change the rotational position as well as horizontal and vertical position of at least the firing barrel component of the firing mechanism is used. In the preferred embodiment detailed in
Force-loading structure 621 connects the body of the rifle and barrel, and applies force to the barrel in the direction indicated by force-indicating arrow 622, driving and seating the barrel and connected chamber, firing pin 609 and, most immediately, spherical gear striker 607 into gear 605. Straight-line moveable, piston-action mount 605a connects gear 605 to the body of the rifle, providing a secure platform and also applying reacting force in the direction opposite to force arrow 622 to aid in maintaining strong gear teeth interface for gear 605 and striker 607, by pushing them together. In alternate embodiments, the hammer element may be omitted and the piston 605a or other striking actuator may itself provide striking force to gear 605, striker 607 and/or firing pin. In this instance, a specialized piston and actuably-rotating armature also may be used, which allows the striking force to be generated in any direction, and more perfectly oppose (be generated 180 degrees from) the barrel and chamber direction, however it may be rotationally actuated at the time of striking—moving gear 605 in a straight-line path direction perpendicular to the tangential plane at the central point of the spherical gear interface. A semi-spherical gear such as 605 with a spherical center located at the distal rotational pivot point of the barrel may, instead, be used (as pictured by alternate gear inner surface shape, teeth omitted, shown as 627), which may aid in creating even opposing force as the gear is actuated. But in that case, the capability for fore and aft shifting of the barrel during rotational actuation will be eliminated unless an additional piston or other actuator for creating for and aft shifting of the barrel and firing mechanism is used. Alternatively, or in addition, uneven gear teeth angles and thickness may be used, as pictured, to create approximately stable striking force at the point of striking, opposing the direction of the barrel and chamber, for any possible point of spherical gear interface. In any event, the system may use a final (firing strike completed) barrel position, to whatever degree the barrel may shift in each rotational position due to striking action, in determining the nature and degree of barrel position actuation to result in hitting the highest priority impact point with a shot. To allow piston 605a to operate at a radially-centered attachment point, hammer 603, if used, may contain a central slot or cavity, or be comprised of two striking pieces, between which such a piston is seated. If the hammer is omitted, an actuable striking force exerter may be connected directly to the barrel and/or striker and/or firing pin, and spherical gearing may be implemented without a spherical gear also serving as a striking or strike-transmission element, as it is in the figure. However, such an embodiment may be more expensive to implement, as it would require electrical or more complex mechanical striking assembly, to allow changing barrel position and still exert a sufficient striking force at all such positions.
Turning back to the embodiments shown in the figure, variable striker holders 623 may prevent firing pin actuation until a firing execution is commanded or carried out—serving as a safety and gear engagement maintenance device. For example, holders 623 may retract into pockets 624 by a system or user electronic command or actuation signal, or simply by being overcome by the force of a hammer strike from hammer 603, toward the spherical striker 607. Alternatively, as discussed above, hammer 603 may be omitted, and straight-line only movable piston mount 605a may itself be system- or firing movement-actuable to strike spherical striker 607 and overcome the holding force of holders 623.
If the system has placed a set N.I.P. indicator for the latest set N.I.P. on the display within a view or representation of the target environment in the sight, according to step 709, or, instead, determined that the N.I.P. “set” button was not depressed, the system may proceed to step 711. In step 711, the system determines whether any N.I.P. indicators have been set by the system, including such indicators that may have been set prior to the possible instance discussed above. If so, the system may proceed to step 713, in which it determines whether N.I.P. adjustments are to be made, for example, based on user input adjusting the position of a set N.I.P., such as by horizontal and vertical position adjusting knobs 247 and 245, from
The system then proceeds to step 721, in which it determines and implements necessary adjustments, as discussed elsewhere in this application, to the firing mechanism such that a projectile fired from the firing mechanism will place a projectile on, or as near as possible to on, the location of any set N.I.P. and indicator with the highest priority within the surrounding environment. If there is no currently set N.I.P. and indicator, the system may treat the intersection of the crosshairs or other reticle or impact point display point, as a set N.I.P. and indicator with the highest priority, and implement the adjustments to the firing mechanism discussed immediately above, with respect to step 721. The system then proceeds to step 723, in which it determines whether a firing command has been given by the system or user. If so, the system causes the firing mechanism to fire. If not, the system returns to the starting position.
To allow such movement of surface components, each component may be connected to the remainder of projectile 801 by hinged joints, such as the examples shown as 810. Each of the seven components of surface 800 are visible in the figure, including a tip component 811, and three sets of one fore and one aft main body component joined together, such as the example shown as 813. Because projectile 801 has longitudinal and approximately trilateral symmetry, only two sets of fore and aft components are visible in the figure as part of the outer surface 800—namely, fore components 815 and 817, and, to which each is connected, respectively, aft components 819 and 821.
In some embodiments, the control unit 805 (if present) may comprise a number of additional subcomponents for detecting and communicating orientation, position and other factors to the external control system. For example, in some embodiments, control unit 805 comprises an accelerometer, for determining movements of probe/projectile 801, as well as its orientation and position relative to the force of gravity. The control unit may also comprise a gyroscope, which may be a directional gyroscope or gyrocompass, or a form of gyroscope otherwise recalibrated periodically according to a reference direction. Preferably, such a gyroscope or gyrocompass is dampened from movement during deployment, to avoid miscalibration or damage during impact of the projectile. As another example, if the control unit is equipped with a G.P.S., or (for example, with its wireless communications atenna(ae) 803 in communication with G.P.S. satellites), indicating its relative orientation and position, a gyroscope or the control system 805 may be periodically recalibrated to indicate a relative orientation of probe 801 with improved accuracy. Similarly, indications from an accelerometer(s) may be used to cross-check movements indicated by a gyroscope or by electromagnetic test signals of the external control system that interact with antennae 803 and/or reflectors 807 (and vice versa). As a side benefit, in some embodiments, the accelerometer(s), gyroscope(s), G.P.S. systems, reflectors and antennae may aid in directing the positioning and orientation of projectile 801 during flight, making projectile 801 a remotely-controlled projectile that can be actively directed to a particular target. For example, using a flight-simulating GUI within the external control system, or an augmented targeting GUI such as those set forth in
As mentioned above, the dynamic operation of components of projectile/probe 801 are treated in more detail, immediately below, in reference to
As tip 811 collides with target wall 900 its sharp profile allows it to pierce the material of the wall and enter it. In some embodiments, a sharper or harder tip material may be used, or a larger launching force may be exerted on projectile 901, to pierce and mount probe 900 in harder, stronger, more robust or more distant materials (e.g., armor). In other embodiments, a softer material or lower launching force may be appropriate for deployment and embedding of the probe into a softer or more flexible material (e.g., clothing of a target person to be probe will be attached and tracked, and future targeting will be defined relative to, as set forth above in reference to
As a result, after the probe 901 is so attached to the target, and fixed in orientation relative to it, and its wireless communications antennae and reflectors become accessible to the external control system of the targeting system (e.g., such as the targeting systems set forth above, in reference to
In some embodiments, additional hardware may also be included within probe 901, and controllable by internal control system 805 (which may itself be controlled by commands and communications from the external control system within the targeting system), to increase the number and variety of options for further dealing with the target. Such additional hardware may include motorized hypodermic needles with drugs held within an attached vessel (e.g., tranquilizers), electric shock-delivering devices, sound-, heat-, light- or gas-generating devices and explosives, or radio beacons, to name just a few possibilities. In some embodiments, probe 901 may include a speaker or two-way communications equipment, for issuing commands or otherwise communicating with a target.
As explained above, because projectile probe 801/901 is physically fixed in position and orientation to a target material, a targeting system employing such a projectile/probe can define relative distances and positions within said target, and a surrounding environment, with greater precision and greater control, and place or alter impact point indicators in relation to the position and orientation of projectile/probe 801/901 after deployment. Although the example of a physical, non-lethal projectile for defining relative positions of a targeting system (and positioning impact point indicators within a sight and/or display) is provided in detail, it should also be understood that any other system component or method for altering a target material, or an object attached to a target material, may also be used. For example, in one embodiment, a laser or other beam-generating sight (e.g., mounted on the body of the rifle or other launcher of projectiles to be fired by the system) comprised in the targeting system may be used, in which a collimated beam of coherent light or an electromagnetic beam is used to heat, marking, “paint” or otherwise alter a point or region of the target material or an object attached to it. Positions relative to the heated, marked or painted region or point may then be detected (e.g., by light, laser or infrared sensors within the system) to define impact points and display them to a user.
