Description

[Technical Field]

[0001] The embodiments of this disclosure relate to a projection transmitter. [Previous Technology]

[0002] A projectile launcher fires one or more projectiles at a target. A conducted electronic weapon ("CEW") is a projectile launcher. The CEW delivers an electric current through the target's tissue. The current may interfere with the target's voluntary movement, such as walking, running, or moving. The current may cause pain or other discomfort, causing the target to cease voluntary movement. The current may interrupt the voluntary control of muscles by stiffening, locking, and / or freezing the target's skeletal muscles, thereby causing neuromuscular dysfunction. This dysfunction interferes with the target's voluntary movement. A typical CEW fires two or more projectiles (e.g., electrodes) to remotely deliver an electric current through the target's tissue.

In some embodiments, control signals from processing circuitry 135 to signal generator 145 may include signals from processing circuitry 135 to provide power to or cut off power to signal generator 145 (e.g., electrical signals to control an electrical switch between power supply 140 and signal generator 145).

[0055] In various embodiments, the signal generator 145 may be located within the handle 110 of the projectile transmitter 100 (e.g., as depicted in FIG1C). In various embodiments, the signal generator 145 may be located within a magazine 112 that houses the signal generator 145.

[0056] In various embodiments, signal generator 145 may be configured to receive one or more control signals from processing circuitry 135. Signal generator 145 may provide an ignition signal to magazine 112 based on the control signals. Signal generator 145 may be electrically and / or electronically coupled to processing circuitry 135 and / or magazine 112. Signal generator 145 may be electrically coupled to power supply 140. Signal generator 145 may use power received from power supply 140 to generate the ignition signal. For example, signal generator 145 may receive an electrical signal having a first current and voltage value from power supply 140. Signal generator 145 may convert the electrical signal into an ignition signal having a second current and voltage value. The converted second current and / or converted second voltage value may be different from the first current and / or voltage value. The converted second current and / or converted second voltage value may be the same as the first current and / or first voltage value. Signal generator 145 may temporarily store power from power supply 140 and rely entirely or partially on the stored power to provide the ignition signal. Signal generator 145 may also rely entirely or partially on received power from power supply 140 to provide the ignition signal without temporarily storing power.

[0057] The signal generator 145 may be wholly or partially controlled by the processing circuitry 135. In various embodiments, the signal generator 145 and the processing circuitry 135 may be separate components (e.g., physically different and / or logically independent). The signal generator 145 and the processing circuitry 135 may be a single component. For example, the control circuitry within the handle 110 may include at least the signal generator 145 and the processing circuitry 135. The control circuitry may also include other components and / or configurations, including further integrating the corresponding functions of these elements into a single component or circuitry, and further separating certain functions into separate components or circuitries.

[0058] The signal generator 145 can be controlled by a control signal to generate an ignition signal having one or more predetermined current values. For example, the signal generator 145 may include a current source. A control signal may be received by the signal generator 145 to activate the current source at a current value. Additional control signals may be received to reduce the current of the current source. For example, the signal generator 145 may include a pulse width modification circuit coupled between the current source and the output of the control circuit. A second control signal may be received by the signal generator 145 to activate the pulse width modification circuit, thereby reducing the non-zero period of the signal generated by the current source and the total current of the ignition signal subsequently output by the control circuit. The pulse width modification circuit may be separate from the circuitry of the current source, or alternatively, integrated within the circuitry of the current source. Various other forms of the signal generator 145 may be used alternatively or additionally, including those that apply voltages across one or more different resistors to generate signals with different currents. In various embodiments, the signal generator 145 may include a high-voltage module configured to deliver a current with a high voltage. In various embodiments, the signal generator 145 may include a low-voltage module configured to deliver a current with a low voltage (e.g., 2,000 volts).

[0059] In response to receiving a signal indicating activation of trigger 115 (e.g., activation event), the control circuitry provides an ignition signal to magazine 112 (or one or more launchers P in magazine 112). For example, signal generator 145 may provide an electrical signal as an ignition signal to magazine 112 in response to receiving a control signal from processing circuitry 135. In various embodiments including CEWs or electrodes, the ignition signal may be independent and different from the stimulation signal. For example, the stimulation signal in projectile launcher 100 may be provided to a different circuit within magazine 112, relative to the circuit providing the ignition signal. Signal generator 145 may be configured to generate the stimulation signal. In various embodiments, a second independent signal generator, component, or circuitry (not shown) within handle 110 may be configured to generate the stimulation signal. Signal generator 145 may also provide a ground signal path to magazine 112, thereby completing the circuitry of the electrical signal provided by signal generator 145 to magazine 112. The ground signal path may also be provided to magazine 112 by other elements in handle 110, including power supply 140.

[0060] In various embodiments, the receiving compartment 111 of the handle 110 may be configured to receive one or more magazines 112. The receiving compartment 111 may include an opening in the deployment end 114, the size and shape of which are adapted to receive one or more magazines 112. The receiving compartment 111 may include one or more mechanical features configured to removably couple one or more magazines 112 within the receiving compartment 111. The receiving compartment 111 may be configured to receive a single magazine, two magazines, three magazines, nine magazines, or any other number of magazines.

[0061] In various embodiments, the magazine 112 may include a housing sized and shaped to be inserted into a receiving chamber 111. The housing may define one or more chambers. Each chamber may define an opening through the housing (e.g., a cavity). Each chamber may be configured to receive projectiles. Each chamber may have a corresponding size and shape to receive and accommodate projectiles before and during projectile deployment of the magazine 112. Each chamber may include any suitable deployment angle. One or more chambers may include similar deployment angles. One or more chambers may include different deployment angles. The housing may include any suitable or desired number of chambers, such as two chambers, five chambers, eight chambers (e.g., as depicted), ten chambers, and / or the like.

[0062] In various embodiments, the magazine 112 may be configured to receive one or more cartridges 156, such as a first cartridge 156-0, a second cartridge 156-1, a third cartridge 156-2, an "Nth" cartridge 156-n, and / or the like. The magazine 112 may be configured to receive a number of cartridges 156 equal to the number of chambers in the magazine 112. Each cartridge 156 may include a body configured to house a projectile, and one or more components necessary for deploying the projectile from the body. The projectile may include a glass-breaking projectile, a flashbang projectile, an electrode projectile, a combination of different projectile types, or any other type of projectile suitable for deployment from the magazine 112. The propulsion module may be similar to any other propulsion module, igniter, or the like disclosed herein. For example, the first ammunition cartridge 156-0 may include a first projectile P0 and a first propulsion module 125-0, the second ammunition cartridge 156-1 may include a second projectile P1 and a second propulsion module 125-1, the third ammunition cartridge 156-2 may include a third projectile P2 and a third propulsion module 125-2, and the Nth ammunition cartridge 156-n may include an Nth projectile Pn and an Nth propulsion module 125-n, etc.

[0063] As described herein, cartridges 156-0, 156-1, 156-2, and 156-n are generally referred to individually as "cartridge 156" or collectively as "cartridges 156". As described herein, projectiles P0, P1, P2, and Pn are generally referred to individually as "projectile P" or collectively as "projectiles P". As described herein, propulsion modules 125-0, 125-1, 125-2, and 125-n are generally referred to individually as "propulsion module 125" or collectively as "propulsion modules 125".

[0064] In various embodiments, each propulsion module 125 may be coupled to or communicate with an individual projectile in the cartridge 156. For example, the first propulsion module 125-0 may communicate with the first projectile P0 (e.g., electrical communication, fluid communication, etc.), the second propulsion module 125-1 may communicate with the second projectile P1, the third propulsion module 125-2 may communicate with the third projectile P2, the Nth propulsion module 125-n may communicate with the Nth projectile Pn, and so on.

[0065] The propulsion module 125 may include any means, propellant (e.g., air, gas, etc.), igniter, or the like, capable of providing propulsion. Propulsion may include an increase in pressure caused by the rapid expansion of gas within a region or chamber (e.g., the interior of the cartridge body). Propulsion may be applied to one or more projectiles P to cause deployment of the projectiles P. The propulsion module 125 may provide propulsion in response to an individual cartridge receiving an ignition signal, as previously described.

[0066] In various embodiments, propulsion can be applied directly to one or more projectiles P. For example, propulsion from propulsion module 125-0 can be directly provided to a first projectile P0, propulsion from propulsion module 125-1 can be directly provided to a second projectile P1, propulsion from propulsion module 125-2 can be directly provided to a third projectile P2, propulsion from propulsion module 125-n can be directly provided to an Nth projectile Pn, and so on. Propulsion module 125 can be in fluid communication with one or more projectiles P to provide propulsion. For example, propulsion from propulsion module 125 can travel to the projectile P within the housing or channel of an individual cartridge 156. Propulsion can travel via a manifold in an individual cartridge 156.

[0067] In various embodiments, propulsion can be indirectly provided to one or more projectiles P. For example, propulsion can be provided to a secondary propellant source within propulsion module 125. Propulsion can launch the secondary propellant source within propulsion module 125, causing the secondary propellant source to release propellant. The force associated with the released propellant can then provide force to one or more projectiles P. The force generated by the secondary propellant source can cause the projectiles P to be deployed from individual cartridges 156.

[0068] In various embodiments, each launcher P0, P1, P2, Pn may include any suitable type of launcher. For example, one or more launchers P may be or include a launcher, an electrode (e.g., an electrode dart), a grappling launcher (e.g., a tethered grappling launcher, a net, etc.), a payload launcher (e.g., including a liquid or gaseous substance), a flashbang launcher (e.g., a pyrotechnic charge that produces a flash and a loud explosion), a glass-breaking launcher (e.g., a ceramic ball that breaks and clears glass), or the like. For example, a flashbang may include magnesium and an oxidizer, and is designed to burn and produce a bright flash and a loud explosion.

[0069] In various embodiments, the signal generator 145 may include one or more cartridges 156 received by the magazine 112 or electrically connected in series therewith. For example, the signal generator 145 may include one or more electrical contactors 105 (e.g., first electrical contactor 105-0, second electrical contactor 105-1, third electrical contactor 105-2, "Nth" electrical contactor 105-n, etc.) or electrically connected in series therewith. The electrical contactors 105 (e.g., handle contactors, handle electrical contactors, signal generator electrical contactors, etc.) may be at least partially exposed within the receiving compartment 111. In response to the magazine 112 being inserted into the receiving compartment 111, the electrical contactors 105 may contact one or more cartridges 156 within the magazine 112 (e.g., as depicted in FIG1C). Each electrical contactor 105 may be configured to be electrically connected in series with one or more cartridges 156, including identical cartridges 156 or individual cartridges 156. For example, the first electrical contactor 105-0 can be electrically connected in series with the signal generator 145 and the first ammunition cartridge 156-0, the second electrical contactor 105-1 can be electrically connected in series with the signal generator 145 and the second ammunition cartridge 156-1, the third electrical contactor 105-2 can be electrically connected in series with the signal generator 145 and the third ammunition cartridge 156-2, and the Nth electrical contactor 105-n can be electrically connected in series with the signal generator 145 and the Nth ammunition cartridge 156-n, etc.

[0070] Signal generator 145 can be configured to provide one or more electrical signals to one or more cartridges 156 via one or more electrical contactors 105. For example, signal generator 145 and / or processing circuitry 135 can control the provision of electrical signals to electrical contactors 105. Signal generator 145 and / or processing circuitry 135 can control the supply of electrical signals by enabling and / or disabling electrical connections (e.g., a first electrical connection, a second electrical connection, a third electrical connection, a next electrical connection, etc.). Electrical connections can define the electrical coupling between signal generator 145 and one or more individual electrical contactors 105. Signal generator 145 and / or processing circuitry 135 can enable and / or disable electrical connections using any suitable techniques or processes, such as by selectively providing electrical signals, turning on and / or off circuits or switches and / or the like. In some embodiments, providing electrical signals may include providing a low-voltage detection signal, an ignition signal, a stimulation signal, and / or the like.

[0071] In various embodiments, cartridge 156 may include an electrical contactor 106 (e.g., cartridge contactor, cartridge electrical contactor, etc.) at the end of its individual cartridge body. For example, first cartridge 156-0 may include a first electrical contactor 106-0, second cartridge 156-1 may include a second electrical contactor 106-1, third cartridge 156-2 may include a third electrical contactor 106-2, and Nth cartridge 156-n may include an "Nth" electrical contactor 106-n and / or the like.

[0072] The electrical contactor 106 can be configured to allow individual cartridges 156 to receive electrical signals from the signal generator 145 via individual contactors 105. For example, the electrical contactor 106 can be configured to complete the circuit between the cartridge 156 and the signal generator 145. In this respect, the electrical contactor 106 can be configured to transmit (or provide) a stimulus signal from the signal generator 145 to an individual projectile P via the electrical contactor 105. As a further example, the electrical contactor 106 can be configured to transmit (or provide) an electrical signal (e.g., an ignition signal) from the signal generator 145 to an individual propulsion module 125 via the electrical contactor 105. For example, the electrical contactor 106 can be configured to transmit (or provide) an electrical signal to a conductor of the propulsion module 125, thereby heating and igniting pyrotechnic material within the propulsion module. The ignition of the pyrotechnic material can cause the propulsion module 125 to deploy (e.g., directly or indirectly) an individual projectile P from the cartridge 156.

[0073] For example, the first cartridge 156-0 may be electrically coupled to the signal generator 145 via the first cartridge electrical contactor 106-0 and the first handle electrical contactor 105-0; the second cartridge 156-1 may be electrically coupled to the signal generator 145 via the second cartridge electrical contactor 106-1 and the second handle electrical contactor 105-1; the third cartridge 156-2 may be electrically coupled to the signal generator 145 via the third cartridge electrical contactor 106-2 and the third handle electrical contactor 105-2; the Nth cartridge 156-n may be electrically coupled to the signal generator 145 via the Nth cartridge electrical contactor 106-n and the Nth handle electrical contactor 105-n; and / or the like.

[0074] In various embodiments, the cartridge electrical contactor 106 may include one or more electrical components configured to be electrically coupled to an individual handle electrical contactor 105 in response to the magazine 112 being inserted into the receiving compartment 111. The cartridge electrical contactor 106 may be configured to provide an electrical signal to an individual cartridge 156, as previously described. The handle electrical contactor 105 may include one or more electrical connectors, such as POGO pins, spring-loaded pins, electrical contactors, electrical probes, and / or the like. For example, one or more handle electrical contactors 105 may include a signal pin. The signal pin may be positioned and configured to provide an electrical signal to the cartridge electrical contactor 106 electrically coupled to the individual handle electrical contactor 105. The signal pin may be configured to be electrically coupled to the cartridge electrical contactor 106 at a center point at the end of the cartridge 156.

[0075] As a further example, one or more handle electrical contactors 105 may include a grounding pin. In some embodiments, the grounding pin may be positioned and configured to provide an electrical signal to a cartridge electrical contactor 106 electrically coupled to the handle electrical contactor 105. In some embodiments, the grounding pin may be positioned and configured to provide an electrical ground. The grounding pin may be located radially outward from the signal pin and may be configured to contact the cartridge electrical contactor 106 at a location different from that of the signal pin.

[0076] In various embodiments, the signal pin may be configured to contact the cartridge electrical contactor 106 at a first position on the cartridge 156, while the ground pin may be configured to contact the cartridge electrical contactor 106 at a second position on the cartridge 156. The first position may be radially inward from the second position. The first position may include a substantially central location on an end of the cartridge 156. The second position may include the outer edge of the end of the cartridge 156. In various embodiments, the signal pin and / or ground pin may be electrically coupled (directly or sequentially) to one or more components of the handle 110, such as the processing circuitry 135, the signal generator 145, and / or the power supply 140.

[0077] In various embodiments, control interface 117 may include or resemble any control interface disclosed herein. Control interface 117 may be configured to control the selection of a firing mode in projectile launcher 100. Controlling the selection of a firing mode in projectile launcher 100 may include disabling deployment from projectile launcher 100 (e.g., safe mode, etc.), enabling deployment from projectile launcher 100 (e.g., active mode, firing mode, upgrade mode, glass-breaking mode, flashbang mode, etc.), controlling the deployment of magazine 112, and / or similar operations. In various embodiments, control interface 117 may also be configured to perform (or trigger the execution of) one or more operations that do not include firing mode selection. For example, control interface 117 may be configured to be able to select an operating mode of projectile launcher 100, select an option within an operating mode of projectile launcher 100, or similar selection or scrolling operations.

[0078] The control interface 117 may be located on the handle 110 or at any suitable location on the handle 110. For example, the control interface 117 may be coupled to an outer surface of the handle 110. The control interface 117 may be coupled to an outer surface of the handle 110 near the trigger 115 and / or a guard of the handle 110. The control interface 117 may be electrically, mechanically, and / or electronically coupled to the processing circuitry 135. In various embodiments, in response to the control interface 117 including electronic features or components, the control interface 117 may be electrically coupled to a power supply 140. The control interface 117 may receive power (e.g., current) from the power supply 140 to power the electronic features or components of the projectile transmitter 100.

[0079] The control interface 117 may be electronically or mechanically coupled to the trigger 115. For example, as further discussed herein, the control interface 117 may serve as a safety mechanism. In response to the control interface 117 being set to "safe mode," the projectile launcher 100 may be unable to fire the projectile P from the magazine 112. For example, the control interface 117 may provide a signal (e.g., a control signal) to the processing circuitry 135, instructing the processing circuitry 135 to disable the deployment of the projectile P from the magazine 112. As a further example, the control interface 117 may electronically or mechanically prevent the trigger 115 from being activated (e.g., preventing or disabling the user from pressing the trigger 115; preventing the trigger 115 from firing the projectile P, etc.).

[0080] The control interface 117 may include any suitable electronic or mechanical components capable of enabling transmission mode selection. For example, the control interface 117 may include a transmission mode selector switch, a safety switch, a safety latch, a rotary switch, a selection switch, a selective transmission mechanism, and / or any other suitable mechanical control. As a further example, the control interface 117 may include a slide rail, such as a pistol slide rail, a reciprocating slide rail, or the like. In some instances, the control interface 117 may include a touchscreen, a user interface, or a display, or similar electronic vision components.

[0081] The safety mode can be configured to prevent the deployment of the projectile P from the magazine 112 in the projectile launcher 100. For example, in response to a user selecting a safety mode, the control interface 117 can transmit a safety mode command to the processing circuitry 135. In response to receiving the safety mode command, the processing circuitry 135 can prevent the deployment of the projectile P from the magazine 112. The processing circuitry 135 can prevent deployment until further instructions (e.g., a firing mode command) are received from the control interface 117. As previously mentioned, the control interface 117 can also, or alternatively, interact with the trigger 115 to prevent activation of the trigger 115. In various embodiments, the safety mode can also be configured to prevent the supply of stimulation signals from the signal generator 145.

[0082] The firing mode can be configured to deploy one or more projectiles P from magazine 112. For example, according to various embodiments, in response to a user selecting a firing mode, control interface 117 can transmit a firing mode command to processing circuitry 135. In response to receiving (or determining) a firing mode command, processing circuitry 135 can initiate the deployment of one or more projectiles P from magazine 112. In this regard, in response to trigger 115 being activated, processing circuitry 135 can trigger the deployment of one or more projectiles P. Processing circuitry 135 can initiate deployment until further instructions (e.g., a safety mode instruction) are received (or determined) from control interface 117. As a further example, according to various embodiments, in response to a user selecting a firing mode, control interface 117 can also mechanically (or electronically) interact with trigger 115 to activate trigger 115.

[0083] In various embodiments, the projected transmitter 100 may further include one or more user interfaces. The user interface may be configured to receive input from and / or send or provide output to a user of the projected transmitter 100. The user interface may be part of the control interface 117. The user interface may be a separate component of the projected transmitter 100 from the control interface 117. The user interface may be located on the handle 110 or at any suitable location on the handle 110. For example, the user interface may be coupled to an outer surface of the handle 110, or may extend at least partially through the outer surface of the handle 110. The user interface may be electrically, mechanically, and / or electronically coupled to the processing circuitry 135. In various embodiments, in response to a user interface including electronic or electrical features or components, the user interface may be electrically coupled to a power supply 140. The user interface may receive power (e.g., current) from the power supply 140 to power the electronic features or components of the projected transmitter 100.

[0084] In various embodiments, the user interface may include one or more components configured to receive input from a user. For example, the user interface may include one or more of the following: an audio capture module (e.g., a microphone) configured to receive audio input; a visual display (e.g., a touch screen, LCD, LED, etc.) configured to receive manual input; a mechanical interface (e.g., a button, switch, etc.) and / or the like configured to receive manual input. In various embodiments, the user interface may include one or more components configured to transmit, provide, and / or generate output. For example, the user interface may include one or more of the following: an audio output module (e.g., an audio speaker) configured to output audio; a light-emitting component (e.g., a flashlight, laser guide, LED, etc.) configured to output light; a visual display (e.g., a touch screen, LCD, LED, etc.) and / or the like configured to output visual information.

[0085] In various embodiments, referring to Figures 2A and 2B, a magazine 212 for a projectile launcher is disclosed. The magazine 212 may be similar to any other magazine or the like disclosed herein.

[0086] The magazine 212 may include a housing 250 (e.g., a magazine housing, magazine body, etc.) sized and shaped to be inserted into a receiving compartment of a launcher handle (e.g., launcher 100). The housing 250 may include a first end 251 (e.g., a deployment end, front end, forward end, etc.) opposite a second end 252 (e.g., a loading end, rear end, etc.). The magazine 212 may be configured to allow the firing of one or more projectiles P from the first end 251 (e.g., projectile P is fired via the first end 251). The magazine 212 may be configured to allow the loading of one or more cartridge cases 156 from the second end 252. The second end 252 may also be configured to allow the supply of an electrical signal (e.g., a stimulant signal, an ignition signal, etc.) from the launcher handle to the cartridge cases 156. The second end 252 may also be configured to allow the supply of propulsion from the launcher handle to one or more cartridge cases 156. In some embodiments, magazine 212 may also be configured to allow loading of one or more cartridges 156 from the first end 251.

[0087] In various embodiments, the housing 250 may define one or more chambers 253. A chamber 253 may include an axial opening through the housing 250, defined and opened at a first end 251 and / or a second end 252. Each chamber 253 may be configured to receive a cartridge case 156. Each chamber 253 may have a corresponding size and shape to receive and accommodate the cartridge case 156 before and during the deployment of the projectile P from the magazine 212. Each chamber 253 may include any suitable deployment angle. One or more chambers 253 may include similar deployment angles. One or more chambers 253 may include different deployment angles. The housing 250 may include any suitable or desired number of chambers 253, such as two chambers, four chambers, eight chambers (e.g., as depicted), ten chambers, and / or the like.

[0088] In operation, one or more cartridge cases 156 can be inserted into one or more chambers 253 of the magazine 212. The magazine 212 can be inserted into the receiving compartment of the launcher handle. The launcher can be operated to deploy one or more projectiles P from the magazine 212. The magazine 212 can be removed from the receiving compartment of the launcher handle. One or more previously deployed cartridge cases 156 (e.g., used cartridge cases 156, fired cartridge cases 156, etc.) can be removed from the chambers 253 of the magazine 212. Then, one or more new cartridge cases 156 can be inserted into the same one or more chambers 253 of the magazine 212 for additional deployment. The number of cartridge cases 156 that the magazine 212 can receive may depend on the number of chambers 253 in the housing 250. For example, in response to a housing 250 including four chambers 253, the magazine 212 can be configured to receive up to four cartridge cases 156 simultaneously. As a further example, in response to a housing 250 including eight chambers 253, a magazine 212 can be configured to receive up to eight cartridge cases 156 simultaneously.

[0089] In various embodiments, referring to Figures 3A and 3B, a cartridge 355 is disclosed. The cartridge 355 may be similar to any other cartridge disclosed herein. The cartridge 355 may include a body 370 (e.g., a cartridge body) having a first end 371 (e.g., a deployment end, a first cartridge end, etc.) opposite a second end 372 (e.g., a contact end, a second cartridge end, etc.). The body 370 may include a cylindrical geometry disposed about an axis extending from the first end 371 to the second end 372. The body 370 may include a single structure or may include separate structures coupled together to form a single body. The body 370 may define an internal channel.

[0090] In various embodiments, the body 370 may include a width 374 (e.g., a base) and an extension 376 (e.g., a firing tube, barrel, etc.). The width 374 may define a second end 372. The extension 376 may define a first end 371. The body 370 may define a step 375 between (and separated from) the width 374 and the extension 376. The step 375 may define an outer surface of the body 370 that extends radially inward relative to the width 374. The step 375 may define an outer surface of the body 370 that extends radially outward relative to the extension 376. In this respect, the width 374 may define the portion of the body 370 from the second end 372 to the step 375, while the extension 376 may define the portion of the body 370 from the first end 371 to the step 375. Internal passages of the body 370 may be defined by the width 374 and the extension 376.

[0091] The width portion 374 and the extension portion 376 may include different dimensions. For example, the width portion 374 may include a first diameter or a first width (e.g., a first cartridge width) and a first length (e.g., a first cartridge length). The extension portion 376 may include a second diameter or a second width (e.g., a second cartridge width) and a second length (e.g., a second cartridge length). In the example of FIG. 3A, the first width of the width portion 374 may be greater than the second width of the extension portion 376 (e.g., the second width may be less than the first width), and the first length may be less than the second length (e.g., the second length may be greater than the first length). Various embodiments may include a first width less than the second width, may include a first length greater than the second length, or may include equal first and second widths or lengths.

[0092] The width portion 374 may include a consistent inner diameter from the first end 371 to the step 375. The extension portion 376 may include a consistent inner diameter from the step 375 to the second end 372. The consistent inner diameter of the width portion 374 may be larger than the consistent inner diameter of the extension portion 376 in the example of FIG3A.

[0093] In the example of FIG. 3C, the extension 376 may include a varying outer diameter. For example, a first portion of the extension 376 near the first end 371 (e.g., a first body portion) may include an outer diameter smaller than a second portion of the extension 376 near the step 375 (e.g., a second body portion). For example, the first portion may include a first outer diameter, while the second portion may include a second outer diameter. The second outer diameter may be larger than the first outer diameter. The width 374 may define a third portion (e.g., a third body portion) including a third outer diameter. The third outer diameter may be larger than each of the second and first outer diameters.

[0094] In some embodiments, the first portion may include a first inner diameter, and the second portion may include a second inner diameter. The first inner diameter may be the same as or substantially the same as the second inner diameter. The third portion may include a third inner diameter. The third inner diameter may be larger than each of the first and second inner diameters.

[0095] In some embodiments, the first portion and the second portion may define equal portions of the extension 376. In some embodiments, the length of the first portion may be less than that of the second portion. For example, the first portion may include a percentage of the length of the second portion, such as 70%, 60%, 50%, 30%, 20%, 10%, or the like. The variation in outer diameter between the first and second portions of the extension 376 may define a step difference (e.g., a second step difference, a blasting door step difference, etc.). The step difference may define the variation in outer diameter between different portions of the extension 376.

[0096] In various embodiments, the body 370 may include an outer surface 378 opposite to the inner surface 379. The outer surface 378 may be configured to contact the chamber of the magazine in response to being inserted into the magazine. The inner surface 379 may define an opening (e.g., chamber, barrel, internal passage, etc.) through the body 370 and is configured to hold pyrotechnic charge and one or more components configured to trigger pyrotechnic charge deployment, such as cartridge internal assemblies.

[0097] In various embodiments, the inner surface 379 of the body 370 may define a shoulder 385 between (and separating from) the width 374 and the extension 376. The shoulder 385 may include the inner surface of the body 370 that extends radially inward relative to the width 374. The shoulder 385 may define the inner surface of the body 370 that extends radially outward relative to the extension 376. The shoulder 385 may include the radially inner surface of the body 370 opposite the step 375.

[0098] In various embodiments, the cartridge 355 may include a breaching door 386 configured to block a first end 371 prior to the deployment of pyrotechnic charge 380 from the cartridge 355. The breaching door 386 may be coupled to the first end 371. The breaching door may be coupled to the first end 371 by press fit, interference fit, adhesive, or other suitable coupling techniques. In some instances, the breaching door 386 includes foil coupled to the first end 371 by an adhesive. In response to the deployment of pyrotechnic charge 380, the breaching door 386 may be decoupled from the first end 371. For example, the breaching door 386 may be decoupled from the first end 371 in response to contact and force applied by the combustion of pyrotechnic charge 380 or powder charge 381. In some embodiments, the force initiating the deployment of pyrotechnic charge from the cartridge 355 may decouple the breaching door 386 without contact or force from the pyrotechnic charge itself. For example, the air pressure or gas pressure difference between the surrounding environment and the internal chamber defined by the cartridge 355 can cause the demolition door 386 to deploy. In some embodiments, the demolition door 386 may include a demolition disc configured to release in response to a gradual pressure buildup inside the cartridge reaching a release threshold. Adjustments can be made sufficient to overcome the pressure buildup in the demolition door 386 to increase or decrease the amount of combustion and pressure buildup before the pyrotechnic charge 380 is projected outward.

[0099] The blasting door 386 may be coupled to the extension 376 (e.g., the first portion of the extension 376). The blasting door 386 may extend axially from the first end 371 toward the second portion of the extension 376 (e.g., toward the step 375, the second end 372, etc.). The blasting door 386 may be opened or decoupled from the extension 376 during deployment.

[0100] In the example of FIG. 3C, the portion of the body 370 near the first end 371 may have the size and shape of receiving the blast door 386. In this respect, the portion of the body 370 near the first end 371 may include different dimensions (e.g., varying dimensions) compared to the rest of the extension 376. For example, the portion of the body 370 near the first end 371 may include an inner diameter substantially similar to or smaller than the outer diameter of the rest of the extension 376 (e.g., a first outer diameter of the extension 376 is larger than a second outer diameter of the body 370 near the first end 371). However, in some embodiments, the extension 376 may have an outer diameter consistent from the first end 371 to the step 375, while the blast door 386 may include a similar inner diameter to facilitate a press fit or interference fit.

[0101] For example, according to various embodiments, detail A of FIG3C depicts the associated widths (e.g., thickness, wall diameter, etc.) of the extension 376, the first end 371, and the blasting door 386. In an example of detail A, the extension 376 may include a first width W1. The first end 371 of the body 370 may include a second width W2. The blasting door 386 may include a third width W3. In some embodiments, the blasting door 386 may include varying widths (e.g., a third width, a fourth width, etc.). For example, the width of the first portion of the blasting door 386 that blocks the opening of the first end 371 may be different from the width of the second portion coupled to the first end 371 of the body 370 (e.g., each end of the blasting door 386). As a further example, the width of the first portion of the blasting door 386 that blocks the opening of the first end 371 may be greater than the width of the second portion coupled to the first end 371 of the body 370 (e.g., each end of the blasting door 386). As a further example, the width of the first portion of the blast door 386 that blocks the opening at the first end 371 may be smaller than the width of the second portion (e.g., each end of the blast door 386) coupled to the first end 371 of the body 370.

[0102] In the example of detail A, the first width W1 may be greater than the second width W2. The first width W1 may be greater than the third width W3. The first width W1 may be greater than the sum of the second width W2 and the third width W3. The first width W1 may be substantially similar to or equal to the sum of the second width W2 and the third width W3. In some embodiments, the extension 376 having a first width W1 that is greater than, substantially similar to, or equal to the sum of the second width W2 and the third width W3 ensures that the cartridge 355 can be properly received within the chamber of the magazine without the blasting door 386 interfering with (or obstructing) the inner surface of the magazine's chamber. In some embodiments, the blasting door may be configured as a plug and may have an outer diameter similar to the inner diameter of the extension 376 to facilitate a press fit or interference fit. In some embodiments, the second width W2 may be greater than the third width W3. The third width W3 may be less than the second width W2. The second width W2 may be substantially similar to or equal to the third width W3.

[0103] In various embodiments, the blast door 386 may be configured to seal the ammunition cartridge 355 at a first end 371. In some embodiments, the blast door 386 may be configured to at least partially seal the internal components of the ammunition cartridge 355 from the external body 370 of the environment. In some embodiments, the blast door 386 may be configured to retain the pyrotechnic charge 380 within the ammunition cartridge 355 prior to deployment.

[0104] In various embodiments, the pyrotechnic charge 380 can be formulated to burn rapidly and / or generate significant noise. The pyrotechnic charge 380 can be disposed within the cartridge case 355 and can comprise combustible material and an oxidizer. In some instances, the pyrotechnic charge 380 may comprise a combination of magnesium, metallic nitrates, chlorates, aluminum, potassium perchlorate, potassium chlorate, sulfur, polytetrafluoroethylene, or other materials suitable for manufacturing or enhancing the effect of the pyrotechnic charge 380. The pyrotechnic charge 380 can be deposited in the cartridge case 355 in powder form as a mixture of combustible material and oxidizer.

[0105] In various embodiments, the pyrotechnic charge 380 may be in front of and near the powder charge 381. The powder charge 381 may include a disposable booster commonly used in high-pressure nail guns. The powder charge 381 may include a radially outwardly expanding rear end 388. In some embodiments, the powder charge 381 may include a blank cartridge case. The powder charge 381 may include a brass cartridge case for holding the gunpowder. The powder charge 381 may be configured to ignite the gunpowder. The powder charge 381 may be configured to ignite the gunpowder in response to a force that impacts and / or contacts the rear end 388. Ignition of the gunpowder may cause ignition of the pyrotechnic charge 380.

[0106] In some embodiments, the rear end 388 of the powder charge 381 may be positioned or pressed against the shoulder 385. Positioning and / or pressing the rear end 388 of the powder charge 381 against the shoulder 385 may at least partially help retain the powder charge 381 within the cartridge 355. Positioning and / or pressing the rear end 388 of the powder charge 381 against the shoulder 385 may at least partially restrict forward movement of the powder charge 381 within the cartridge 355.

[0107] An annular spacer 383 may be configured to hold the powder charge 381 on the shoulder 385. The spacer 383 may be configured to at least partially assist in holding the powder charge 381 within the cartridge 355. The spacer 383 may also be configured to at least partially restrict rearward movement of the powder charge 381 within the cartridge 355. The spacer 383 may include plastic, metal, alloy, composite material, moldable material, ceramic, or other material suitable for positioning and holding the powder charge 381. The spacer 383 may include a profiled fixed surface 382 sized and shaped to receive the rear end 388 of the powder charge 381. The spacer 383 may press-fit into the inner diameter 384 of the cartridge 355. The inner surface 387 of the spacer 383 may define an internal channel from the propulsion module 325 to the rear end 388 of the powder charge 381. In response to combustion of the igniter 318, the igniter cap 320 can travel through the inner channel defined by the inner surface 387 to impact the rear end 388 of the powder charge 381.

[0108] In various embodiments, spacer 383 may be axially shortened, and a second spacer may be positioned in front of rear end 388 to position powder charge 381 rearward from deployment end 371 and shoulder 385. The second spacer may comprise a sufficiently rigid metal or other material to support clamping of rear end 388 to release powder charge 381. Shortening spacer 383 and adding a second spacer in front of powder charge 381 may increase the volume of extension 376 to hold pyrotechnic charge 380.

[0109] In various embodiments, the cartridge 355 may include a propulsion module 325 disposed within the body 370. The propulsion module 325 may be configured to provide propulsion to trigger the deployment of pyrotechnic charge from the cartridge 355. The propulsion module 325 may be similar to any other propulsion module disclosed herein. In some embodiments, the propulsion module 325 may be similar to the propulsion module, propulsion device, and / or the like described in U.S. Patent Application No. 16 / 153,640, filed October 5, 2018, which is incorporated herein by reference in its entirety.

[0110] In various embodiments, the propulsion module 325 may be disposed after the spacer 383. The propulsion module 325 may be controlled to provide rapidly expanding gas. The propulsion module 325 may be ignited to launch a burning pyrotechnic charge from the cartridge 355. For example, the propulsion module 325 may include an igniter 318. The igniter may be ignited in any manner, such as by impact (e.g., tapping) motion that directly or indirectly contacts the igniter or by energizing it with an electric current. When electrically ignited, the current may include direct current or alternating current. In some embodiments, the current used to ignite the igniter may be a pulsed current or a current provided in the form of a step function. The polarity of the current may be positive or negative.

[0111] In some embodiments, the igniter can be ignited via a mechanical impact force. For example, a mechanical impact force can be applied to contactor 357. The impact force can be transferred from contactor 357 to propulsion module 325. The impact force can pierce (e.g., penetrate) and / or crush (e.g., compress) the igniter in propulsion module 325, thereby initiating (e.g., activating) a chemical reaction in the igniter that causes the pyrotechnic material of the igniter to burn (e.g., ignite). The combustion of the igniter produces rapidly expanding gases. The impact force can be provided by any object, such as a firing pin.

[0112] In other embodiments, the propulsion module 325 may be ignited via an electric current. For example, the current may be supplied to a contactor 357. The contactor 357 may include an electrical path (e.g., a conductor) that allows current to flow from the contactor 357 to the propulsion module 325. The contactor 357 may include a mechanical structure that includes an electrical path to an igniter in the propulsion module 325. The current flowing to the igniter may heat the conductor, thereby igniting the pyrotechnic material within the igniter. The electrical path of the current may include the contactor 357, the propulsion module 325, and / or the body 370. For example, the body 370 may be grounded, and a voltage having a positive or negative polarity may be applied to the contactor 357 to induce current to flow from the contactor 357 to the propulsion module 325. Ignition of the pyrotechnic material in the igniter of the propulsion module 325 produces a rapidly expanding gas that is configured to deploy the pyrotechnic charge.

[0113] In some embodiments, the propulsion module 325 may include compressed gas sealed in a chamber. The compressed gas may be released in response to a physical or electrical input at contactor 357. The input may open a release valve or penetrate a seal, causing the compressed gas to rapidly expand out of the chamber.

[0114] In various embodiments, the cartridge 355 may include an igniter cap 320 disposed within the body 370. The igniter cap 320 may be coupled to the propulsion module 325. The igniter cap 320 may include components of the propulsion module 325. The igniter cap 320 may be disposed within the body 370 in front of the propulsion module 325. The igniter cap 320 may be configured to move in a forward direction (e.g., toward the first end 371) in response to a propulsive force caused by ignition of the igniter 318 in the propulsion module 325.

[0115] In various embodiments, the cartridge 355 may include an internal cartridge assembly. The internal cartridge assembly may include one or more components configured to assist in the deployment of pyrotechnic charges from the cartridge 355, providing a stimuli signal and / or the like via the projectile. For example, the internal cartridge assembly may include one or more of a propulsion module, one or more spacers, an intermediate impact member, or a powder charge.

[0116] In various embodiments, cartridge 355 may include a disposable cartridge. In some embodiments, cartridge 355 may be reusable. After the pyrotechnic charge 380 is deployed from cartridge 355, one or more components of the internal components of the cartridge may be replaced. For example, after the pyrotechnic charge 380 is deployed, the propulsion module 325 may be depleted, the igniter cap 320 may be displaced, the powder charge 381 may be consumed, the pyrotechnic charge 380 may be released, etc. Replacing components of the internal components of the cartridge allows the body 370 of cartridge 355 to be reused for a subsequent second deployment of a second projectile. For example, the depleted propulsion module may be removed from the second end 372, and a new propulsion module 325 may be coupled to cartridge 355 in its position.

[0117] In various embodiments, one or more components of the internal assembly of the cartridge can be removed from the second end 372. The second end 372 and the body 370 may be sized and shaped to allow removal of one or more components. For example, in some embodiments, a contactor 357 may be coupled to and block the second end 372. In other embodiments, the contactor 357 may be part of a propulsion module 325, the rear surface of which may be coupled to and block the second end 372. The contactor 357 and / or the propulsion module 325 may be decoupled from the second end 372 to remove one or more components of the internal assembly of the cartridge from the second end 372. The powder charge 381 may remain within the cartridge 355 after firing. A spacer 383 and a shoulder 385 may hold the powder charge 381 in place after firing. The spacer 383 and the powder charge 381 may be removed from the second end 372.

[0118] Referring to Figures 3C and 3D, deployment of a cartridge 355 is shown according to various embodiments. The cartridge 355 may include a contactor 357 disposed near (or at) a second end 372. The contactor 357 may be similar to any other contactor disclosed herein. The contactor 357 may be configured to allow the cartridge 355 to receive electrical signals from a CEW handle, a projectile launcher, or other deployment platform. For example, the contactor 357 may include an electrical contactor configured to complete circuitry between the cartridge 355 and a signal generator of the CEW handle. In this respect, the contactor 357 may be configured to transmit (or provide) an electrical signal (e.g., an ignition signal) from the CEW handle to the propulsion module 325 within the cartridge 355. As a further example, according to some embodiments, the contactor 357 may be configured to interface with the signal pins of the deployment platform, while the body 370 may be configured to interface with the ground pins of the deployment platform.

[0119] For example, contactor 357 may be configured to transmit an electrical signal to conductor 319 of propulsion module 325, thereby heating conductor 319 and igniting igniter 318 of propulsion module 325. Ignition of igniter may cause propulsion module to deploy (e.g., directly or indirectly) pyrotechnic charge 380 from cartridge 355.

[0120] In the examples of Figures 3C and 3D, the igniter 318 accelerates the igniter cap 320 forward into the rear end 388 of the powder charge 381 via an electrical ignition signal. In response to the forward translation of the igniter cap 320, the rear end 388 of the powder charge 381 is clamped between the igniter cap 320 and the shoulder 385 (or a secondary spacer, if applicable). The sudden impact and clamping cause the rear end 388 of the powder charge 381 to ignite. Therefore, the propulsion module 325 of the cartridge 355 can be electrically launched, and can cause the secondary powder charge 381 or secondary igniter to be launched, thereby causing the ignition and deployment of the pyrotechnic charge 380. Thus, the cartridge 355 can release the pyrotechnic charge (e.g., a flashbang) in response to an electronic launch signal.

[0121] According to various embodiments, the powder charge 381 may be disposed after the pyrotechnic charge 380. The powder charge 381 may extend from the width 374 into the extension 376 of the cartridge 355. The powder charge 381 may be fired in response to an impact on the rear end 388. An impact on or around the peripheral region of the rear end 388 may cause the rear end 388 to be clamped onto the shoulder 385. The sudden clamping movement may ignite the gunpowder within the powder charge 381, causing the flammable powder within the powder charge 381 to burn (e.g., ignite, release, etc.). The combustion of the powder charge 381 ignites the pyrotechnic charge 380 and propels the pyrotechnic charge 380 forward and outward from the deployment end 371. The ignition of the pyrotechnic charge 380 may trigger a rapid expansion of the gas in the volume 321.

[0122] In some embodiments, an intermediate impact member may be disposed between the igniter cap 320 and the rear end 388 of the powder charge 381. The intermediate impact member may receive impacts from the igniter cap 320 and redirect the force to a peripheral region of the rear end 388. The intermediate impact member may include sharp or rounded features to distribute pressure to desired locations on the rear end 388. In some embodiments, the intermediate impact member may include a single sharp feature to amplify the pressure applied at a desired point on the rear end 388.

[0123] In the example of Figure 3D, the igniter 318 has burned, causing the gas in the volume 321 after the igniter cap 320 to expand rapidly. The combustion of the igniter 318 may cause pressure to be generated in the volume 321, which may initially be defined between the igniter cap 320 and one or more of the sealing structure 322 of the propulsion module 325, the body 370 of the propulsion module 325, or the residue of the consumed igniter 318.

[0124] As the igniter cap 320 translates in the forward direction, it may impact the rear end 388 of the powder charge 381 and cause the wall of the rear end 388 to deflect forward. The rear end 388 of the igniter cap 320 may be configured to receive propulsion force directly or indirectly from the propulsion module 325. The front end may be configured to transfer or provide force to the powder charge 381 to ignite and deploy the pyrotechnic charge 380 from the cartridge 355.

[0125] In various embodiments, the burning pyrotechnic charge 380 can exit from the first end 371 of the cartridge 355 in a substantially conical pattern. The exit velocity of the pyrotechnic charge 380 from the cartridge 355 can be adjusted to a desired level by adjusting the volume available for the pyrotechnic charge 180 or by adjusting the amount of combustible material in the powder charge 381. The combustion or firing rate of the pyrotechnic charge 380 can be controlled at what distance from the cartridge 355 the explosion is completed. For example, the muzzle flash or visible combustion of the pyrotechnic charge may be limited to within 1 foot (0.3048 m), 2 feet (0.6096 m), 3 feet (0.9144 m), 4 feet (1.2192 m), or 5 feet (1.524 m) of the cartridge 355. Limiting the combustion volume of the deployed pyrotechnic charge 380 tends to limit potential fire or combustion hazards. The pyrotechnic charge 380 can be configured to burn rapidly, typically burning before the pyrotechnic charge reaches the ground in response to deployment.

[0126] The flashbang cartridge of this disclosure is adaptable to compatible launch platforms to stun, disorient, and / or incapacitate targets using a near-instantaneous burst of bright light and loud noise. For example, the flashbang cartridge can provide alternative use cases for projectile launchers, CEWs, and / or other mobile launch platforms. The flashbang cartridge detonates within the cartridge, which is held in the launch platform. Therefore, the flashbang cartridge can include handheld or platform-held flashbangs, enabling precise timing and directional deployment. The cartridge can be reloaded for use, and the magazine can be reloaded with cartridges, enabling efficient reuse. The cartridge can be interchanged with different types of cartridges (e.g., cartridges containing electrodes and leads of conventional CEWs), allowing a single firing platform to carry different payloads for different purposes.

[0127] In various embodiments, a cartridge case is disclosed. The cartridge case may include a body comprising a wide portion and an extension connected by a shoulder. The cartridge case may include an igniter cap configured to translate in a forward direction. The cartridge case may include a spacer in front of the igniter cap. The igniter cap may be configured to translate through the spacer in a forward direction. The cartridge case may include a powder charge in front of the spacer, wherein the rear end of the powder charge is exposed from the spacer. The powder charge may extend to the extension of the body. The cartridge case may include a pyrotechnic charge in front of the powder charge.

[0128] In various embodiments, the cartridge case may further include a propulsion module. The propulsion module may include a conductor configured to receive an electrical signal. The propulsion module may include an igniter near the conductor, configured to ignite in response to the electrical signal. The propulsion module may include an igniter cap. Ignition of the igniter may cause the igniter cap to translate forward.

[0129] In various embodiments, the igniter cap may impact the rear end of the powder charge, igniting combustion of the powder charge. The pyrotechnic charge may ignite and depart from the front end of the body in response to the combustion of the powder charge. The pyrotechnic charge may include an oxidizer mixed with at least one of aluminum or magnesium. The spacer may include a contoured retaining surface configured to position the powder charge against a shoulder of the body. The cartridge may further include a contactor disposed at the rear end of the body and configured to receive an electrical signal from a deployment platform, the electrical signal being configured to translate the igniter cap in a forward direction. The cartridge may further include a blasting disc coupled to the front end of the body.

[0130] In various embodiments, a deployment platform is disclosed. The deployment platform can be deployed in response to an electrical signal. The deployment platform may include a housing defining a barrel. The deployment platform may include a cartridge case disposed in the barrel. The cartridge case may include a body having an inner surface defining an internal channel. The cartridge case may include a propulsion module in the internal channel and be configured to expand gas in response to an electrical signal. The cartridge case may include a powder charge in the internal channel and adjacent to the propulsion module. The cartridge case may include a pyrotechnic charge in the internal channel adjacent to the powder charge.

[0131] In various embodiments, the deployment platform may further include a magazine removably coupled to the deployment platform, wherein the magazine includes a housing. The deployment platform may include an unmanned vehicle. The propulsion module may include a conductor configured to receive an electrical signal; an igniter configured to ignite in response to an electrical signal; and an igniter cap disposed between the igniter and the rear end of the powder charge, the igniter cap being capable of striking the rear end of the powder charge in response to ignition of the igniter.

[0132] In various embodiments, a cartridge case is disclosed. The cartridge case may include a body having an inner surface that defines an internal channel. The cartridge case may include a propulsion module coupled to the inner surface at a rear end of the body. The propulsion module may be configured to expand gas in response to an electrical signal. The cartridge case may include a powder charge disposed in the internal channel and in front of the propulsion module. The cartridge case may include a pyrotechnic charge disposed in the internal channel and in front of the powder charge. The cartridge case may include a door coupled to a front end of the body.

[0133] In various embodiments, the propulsion module may include a conductor configured to receive an electrical signal. The propulsion module may include an igniter near the conductor, configured to ignite in response to the electrical signal. The propulsion module may include an igniter cap disposed between the igniter and the rear end of the powder charge. The igniter cap may impinge on the rear end of the powder charge in response to gas expansion. The powder charge may ignite in response to the igniter cap impinging on the rear end of the powder charge. The pyrotechnic charge may ignite and leave the front end of the body in response to the combustion of the powder charge.

[0134] In various embodiments, the pyrotechnic charge may include an oxidizer mixed with at least one of aluminum or magnesium. The cartridge may further include a spacer disposed between the propulsion module and the powder charge. The spacer may position the rear periphery against the shoulder of the body.
