DETAILED DESCRIPTION OF THE DISCLOSURE

[0024] The exemplary embodiments described herein detail for illustrative purposes are subject to many variations in structure and design. It should be emphasized, however, that the present disclosure is not limited to a particular projectile or projectile launcher as shown and described. That is, it is understood that various omissions and substitutions of equivalents are contemplated as circumstances may suggest or render expedient, but these are intended to cover the application or implementation without departing from the spirit or scope of the claims of the present disclosure. The terms first, second, and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, and the terms a and an herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item.

[0025] The present disclosure provides for a projectile 100 and a launcher 1000, and, in an embodiment, a launcher accessory 1100. The projectile 100 preferably comprises a payload 200 for immobilizing and/or marking a target or suspect. It will be understood that payload as used herein may also comprise a substance, object, compound, or material that is capable of delivering a lethal or incapacitating force to and/or resulting in a lethal or incapacitating effect upon a target

[0026] The projectile 100 preferably comprises an enclosure, which enclosure may be formed by an at least partially annular-shaped shell 102. The shell may include a closed, substantially planar end portion 104 (also referred to herein as end cap) that corresponds to a radius of the annular portion of the shell to form the enclosure. The shell and end portion may individually and collectively refer to herein as a housing of projectile 100. It will be apparent that the projectile housing is not limited to the shell and end portion configuration mentioned in the preceding exemplary embodiment, and that the projectile housing may comprise any shape that forms an enclosure without deviating from the spirit of the disclosure, such as, but not necessarily limited to a sphere or a cone. The payload 200 is preferably contained in the enclosure prior to launch of the projectile 100.

[0027] In an embodiment, the projectile 100 is capable of self-separating, disintegrating or otherwise opening prior to impact with a target or other impact surface. In an embodiment, the launcher 1000 is capable of initiating separation or disintegration or rupturing or opening, etc. of the projectile 100. In an embodiment, the launcher 1000 is capable of communicating to the projectile 100 and or arming a projectile 100 prior to or coincident with projectile launch. In another embodiment, the launcher comprises a safety and/or trigger, which safety and/or trigger, until activated, prevent the projectile from becoming armed. The arming can be, for example, the activation of an initiator contained within the projectile.

[0028] In another embodiment and as shown in FIG. 1A, the launcher comprises at least one permanent magnet 500. The at least one magnet 500 may be disposed within or in proximity to the barrel of the launcher, and in a further embodiment, proximate to the point of projectile exit, and in any event along the launch axis of the projectile. (See FIG. 1, for example). The at least one magnet 500 is preferably magnetically-aligned with the launch axis. In a further embodiment, a launcher accessory 1100 comprises at least one permanent magnet 1500 (see FIG. 7, for example). The launcher accessory may be removably attachable to a launcher 1000, and the at least one magnet 1500 of the accessory may be disposed along the launch axis of the projectile that is to be launched by the launcher.

[0029] In an embodiment, and as shown in an exemplary embodiment in FIG. 6, the projectile comprises at least one coil of wire 550. When the projectile is launched, the at least one magnet 500 of the launcher and/or the at least one magnet 1500 of the launcher accessory 1100 causes a rapid change in magnetic flux of coil 550 of the moving projectile. This rapid change causes a current to be induced through the coil 550 of the projectile, causing an inductive energy to be produced. The resultant energy can be used to cause an initiator (described elsewhere herein) to be activated, for example. That is, electrical energy can be generated in this embodiment from the change in magnetic flux as the projectile moves through the magnetic field caused by the at least one magnet 500 and/or 1500.

[0030] An exemplary launcher 1000 is shown in FIG. 1A. The launcher comprises a barrel 1010 for directing and launching a projectile 100. The launcher 1000 may also comprise a chamber 1015 for holding a projectile prior to firing thereof. It will be apparent that the launcher 1000 shown in FIG. 1a may be in other configurations so long as the launcher 1000 is capable of firing a projectile 100 of the projectiles disclosed herein.

[0031] In an embodiment, the projectile 100 housing opens or otherwise separates (as shown in FIG. 2 as 100a and 100b) after it leaves the barrel 1010 of a launcher 1000 to distribute a payload. That is, the rupturing or breaching of the projectile housing or the separation of housing components creates an opening in the projectile 100 out of which the payload 200 may emanate.

[0032] As shown in FIG. 3, the launcher and projectile system may comprise a magazine 1040 that holds a plurality of projectiles 100 and that feeds said projectiles 100 to the launcher 1000 for firing/launching the projectiles 100.

[0033] In an embodiment, and as shown in FIG. 4, the initiator 150 may be an electric match, which electric match may heat upon activation to create an opening in the shell of the projectile 100 to release the payload 200. It will be apparent that the initiator may be activated by the at least one magnet 500 of the launcher and/or the at least one magnet 1500 of the launcher accessory. In said embodiment, the initiator will initiate opening of the projectile immediately or shortly after exiting the launcher. This would be desirable in a short-range situation, for example.

[0034] In another embodiment, the initiator 150 comprises a resistive heating element, which may element becomes heated upon receiving energy from the coil 550 of wire of the projectile 100. The element, in its heated state, preferably causes the shell of the projectile 100 to degrade and rupture to release the payload.

[0035] In another embodiment, the initiator 150 comprises a nichrome wire coupled with a mechanical energy storage means (such as a spring). In this configuration, the mechanical energy storage means may be disposed within the projectile 100 such that it is biased against the shell 102. When the projectile is launched, the energy from the coil 550 of wire (generated by the movement of the projectile 150 through the magnetic field caused by the at least one magnet 500 and/or 1500) may cause the nichrome wire to heat such that the heat may cause the shell 102 to weaken and/or melt. In the weakened state, the potential energy of the mechanical energy storage may be converted to kinetic energy to cause the weakened shell 102 to rupture sch that the payload is released.

[0036] In an embodiment, activation of the initiator 150 does not occur until the projectile 100 reaches a threshold velocity. In an embodiment, the threshold velocity is between 50 and 300 feet per second. In such an embodiment, the initiator is configured not to activate until a threshold minimum current is reached. As the induced voltage in a coil of wire 550 is directly proportional to change in magnetic flux divided by the change in time, if the change in time is lower (i.e. the projectile 100 passes through the magnetic field lines of the permanent magnet at a higher velocity), a higher voltage in the projectile coil 550 will be induced and hence a higher current will be moved through the coil 550 to the initiator 150. Therefore, the projectile 100 must be traveling with sufficient threshold velocity to induce this threshold current value for activation of the initiator 150.

[0037] In another embodiment, and as shown in FIG. 5, the projectile 100 may comprise a ram 108. The ram 108 is movable within the housing of the projectile such that when the initiator 150 (such as an electric match) activates, the ram 108 is moved by the force activation. In an embodiment, the ram 108 is proximate to a portion of the interior of the shell 102 such that the movement of the ram 108 caused by the initiator contacts and causes the shell to separate, rupture, open, etc. such that the payload may be released from the shell. In such an embodiment, the payload may also be proximate to the region of the shell 102 that is contacted by the ram 108 and/or that is opened by the ram 108. An exemplary opening of the projectile is shown in FIG. 5 in which a moving projectile 100 has disrupted the static field lines 501 (being generated by a magnetic element/s 500) to activate the initiator 150, which accelerates the ram 108, such that the end cap 104 is ejected, and the payload 200 is thereafter dispersed. Stoppers 109 may be provided to ensure that the ram 108 does not eject with the payload 200 and end cap 104.

[0038] Referring now to FIG. 7, a launcher accessory 1100 for a launcher is shown. The launcher accessory 1100 comprises at least one magnet 1500. The launcher accessory 1100 may be removably attached to a launcher (including, but not necessarily limited to launcher 1000). The accessory 1100 is preferably attached to a launcher such that the at least one magnet 1500 of the accessory 1100 is disposed in sufficient proximity to the launch axis of the launcher to facilitate launch of the projectile 100 and to engage the coil of wire 550 of the projectile 100 prior to or coincident with launch of the projectile. FIG. 7 also shows exemplary magnetic flux lines 1501 through which a projectile may pass and which may engage the coil of wire 550 of the projectile. In this exemplary embodiment, the magnetic flux 1501 is disposed along the launch axis of the accessory 1100 and is accordingly magnetically aligned with path of the projectile's launch. In an embodiment, the accessory 1100 is an elongated cylinder in shape, with a circumference that corresponds to the circumference of the barrel of the launcher to which the accessory 1100 is attached. Attachment of the accessory 1100 to the launcher 1000 may be by way of complementary engagement features, by a friction- or press-fit engagement, or by threaded connection, for example.

[0039] As shown in FIG. 7, the launcher 1000 may comprise a trigger 1080 to initiate the launch process. It will be apparent that the activation of the initiator by the launcher and/or launcher accessory eliminates the requirement that the projectile comprise a self-contained power source (i.e., a battery for the projectile is not required), thereby eliminating the possibility that the projectile will suffer a power drain prior to launch.

[0040] FIG. 1 represents a projectile launcher 1000 that is preferably based on electrical-driven or a combination of electrical and combustion or compressed gas means. It is understood that the projectile is not limited to a particular launching method. In an embodiment, the projectile herein is of lightweight construction (for at least the reason that it does not require an internal battery), such that compressed gas can sufficiently and effectively launch the projectile. However, the disclosure may, in other embodiments include, a primer and/or propellant on the projectile and a hammer of the launcher to strike such primer, as well as other means of launching the projectile other than by way of compressed gas.

[0041] The projectile, launcher, and launcher accessory disclosed herein offer the advantages of more controlled release of payload than existing solutions can offer. The projectile further does not require impact upon a target. Configuration of the shell of the projectile disclosed herein may also increase accuracy of flight of the projectile to further improve the safety of use of the projectile disclosed herein. Furthermore, the projectile can be kept in an unarmed state until the projectile is launched from the launcher.

[0042] The foregoing descriptions of specific embodiments of the present disclosure have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present disclosure to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiment was chosen and described in order to best explain the principles of the present disclosure and its practical application, to thereby enable others skilled in the art to best utilize the disclosure and various embodiments with various modifications as are suited to the particular use contemplated.
