This disclosure, in general, relates to a mounting system for mounting auxiliary devices to firearms, methods of using such mounting systems, methods of manufacturing such mounting systems.
As demand has increased for firearms, so too has demand for auxiliary devices, such as laser sights, infrared light sources, and visible light spectrum sources. Demand for such auxiliary devices is particularly strong in military, civilian defense, and police applications. Many operations occur at night or in low light conditions, rendering weapon mounted lighting systems desirable. But, such systems tend to suffer from deficiencies in power limitations, activation methodologies, and the obstruction of a firearm user's forward view.
As such, improved auxiliary devices and associated mounting systems would be desirable.
The present disclosure may be better understood, and its numerous features and advantages made apparent to those skilled in the art by referencing the accompanying drawings.
The use of the same reference symbols in different drawings indicates similar or identical items.
In an exemplary embodiment, a mounting system includes a rail system. The rail system can include a plurality of powered rails and at least one control rail. The rail system can be disposed on a firearm, extending along the barrel toward a front of the firearm. The front or forward direction of the firearm extends from the trigger toward the distal end of the barrel. The rail system can extend along the barrel forward of the trigger, stock, and firearm handle.
A control handle that includes a power supply is attached to the control rail of the rail system to provide power to the plurality of powered rails of the rail system. Accessory devices can be mounted to the rail system, for example, to the powered rails. The powered rails can provide power to the accessory devices. An exemplary accessory device includes a visible light source, an infrared light source, a laser source, or combination thereof. In an example, the handle includes a control interface that interfaces with the control rail, provides power to the powered rails, and includes a mode select button and an activation button. A select mode can be activated by selecting a particular mode using the modes select button and depressing the activation button. Optionally, a head device including one or more light sources is attached to the front end of the rail system. In an example, the head device includes a plurality of visible light spectrum light sources and plurality of infrared light sources. Optionally, the head device can include a laser light source.
In another exemplary embodiment, a head device disposed toward a front of the firearm, optionally attached to a rail system, includes a plurality of light sources. In an example, the head device includes a plurality of visible light sources and a plurality of infrared light sources. In an example, the head device can also include a plurality of laser light sources. In a particular example, the visible light sources are disposed to project forward from the head device on opposite sides of a vertical axis of symmetry of the head device. Two of the plurality of infrared light sources can be disposed on opposite sides of the vertical axis of symmetry. For example, a first of the plurality of infrared light sources is disposed on a first side of the axis of symmetry and a second of the plurality of infrared light sources is disposed on the other side of the vertical axis of symmetry. The head device can further include a mounting connector for connecting the device to a mounting system of a firearm. In an example, the mounting system is a rail system and the mounting connector of the head device is attached to a rail of the rail system.
In an exemplary embodiment illustrated in
Along the barrel 112 and forward of the stock 106, firearm handle 104, and trigger 110 is disposed a rail mounting system 114, forming part of a handguard. The rail mounting system 114 can include a plurality of rails to which auxiliary devices are optionally attached and can include a control rail to which a control handle 116 is attached. Optionally, a head device 118 can be attached to the rail mounting system 114, and the head device 118 can be controlled by the control handle 116 through the rail mounting system 114, through a wire interface 120, or through a unitary or solid electrical connector formed or connected between the head device 118 and the handle 116.
In a particular example illustrated in
In an example, a head device includes a housing, main light assembly, infrared (IR) light assemblies, a powered cradle, internal wiring, a fixed connector, a floating connector, an insulating substance, or a back plate. For example, as illustrated in
The housing 302 defines a central bore 318 through which the barrel extends or through which a bullet may pass. The housing 302 can further define a connector 314 to assist with connecting the head device 300 to a rail mounting system. In an example, the connector 314 is disposed at a top of the head device 300 and defines a structure similar to a rail to which the head device 300 is to be mounted. A complementary connector connecting a rail of the rail mounting system to the rail connector 314 can provide interconnection between the rail mounting system and the head device 300. Alternatively, the connector 314 can be fixed rail mounting device or structure. In an example, the connector 314 is a fixed rail connector having a complementary Picatinny configuration or a KeyMod configuration.
The head device 300 can further include a second connector 316 to optionally connect the head device 300 to the rail mounting system. Alternatively, the connector 316 can be floating connector or can allow connection of additional devices to the head device 300. In a particular example, the second connector 316 is disposed near the bottom of the head device 300.
In an example, the head device 300 can be formed of a heat resistant material, such as a high temperature plastic polymer or metal. For example, the housing 302 can be made from thermal molded plastic, cast or milled metal, or other appropriate materials.
A back plate 304 can be connected to the housing 302 to form a watertight sealed housing. A waterproof electronic connector 426 can connect to the back plate 304 of the head device 300. In particular example, when viewed from the rear, the electronic connector 426 is disposed on the left side of the head device 300.
As illustrated in
An adjustable connector 316 can be used to provide further support and connect the head device 300 to the rail mounting system 428. Alternatively, the connector and interface 316 can connect the head device 300 to additional devices. In an example, an additional device includes a Taser, laser, camera, night vision, solar charging assembly, weights for recoil or rise compensation, or any combination thereof.
In an additional example, the head device 300 can include an interface to attach additional equipment to the connector of the head device 300. For example, the connector 316 can be adjusted to connect other devices to a bottom of the head device. The connector 316 can include an electronic interface for controlling the additional device. Alternatively, a split cable can be provided that includes an interface for the electrical connector 426 and connections for the additional device.
In a particular example, a power cradle can be defined under and protected by plate 440. The power cradle can include a floating connector and can further define an internal well and a track which allow the floating connector to move in and out of the housing. In another example, the powered cradle includes a powered connector to receive an auxiliary device, such as a camera, thermal camera, laser, Taser, thermal sensor, sound sensor, tracking device delivery system, weights for recoil and rise compensation, night vision, a solar charging assembly or a combination thereof. In an example, a plurality (e.g., two, three, or four) metal cradle tabs connect the wiring harness of the internal wiring to the powered cradle at cradle slots, which can be used to control an auxiliary device attached to the power cradle.
In an example, internal wiring includes circuitry, connections, and shielded or unshielded wire, which can be used to deliver electrical power to the various components of the device. The internal wiring can be configured in a Y-shaped harness, delivering power from the power connector multi controller (e.g., the electrical connector 426 or an internal power source) to the powered cradle, the main light assemblies 308, and the IR light assemblies 310. The internal wiring can be secured to the components with locking connectors at each of the nodes.
In a further example, the head device 300 can be filled with a heat resistant or electrically insulative medium. For example, an electrical and thermal insulating substance in the form of a gel, paste, epoxy, or other viscous medium can be used to cover the electrical connections and components interior to the housing 302. A rear gasket and back plate 304 can attach to the beveled rear opening of the housing 302, and can be fixed in place, for example, by back plate screws through back plate screw holes.
A power connector hole at the lower portion of the back plate houses the female power connector (e.g., electrical connector 426), which can be sealed by a power connector O-ring, a power connector nut, and power connector sealant. In an example, the female power connector is a four post, four ground connector, or a similarly configure connector. In a particular example, the female power connector can be attached to an external multi-controller and power source which powers and facilitates various modes of operation for the main light assemblies, IR light assemblies, and powered cradle of the head device 300.
As illustrated in
As further illustrate in
When viewed from the front as illustrated in
In addition, the plurality of infrared light sources 310 can be disposed within the housing 302. For example, a set of infrared light sources can be disposed on a first side of the axis of symmetry 950, and another set of the infrared (IR) light sources can be disposed at opposite side of the axis of symmetry 950. In an example, the sets of IR light sources can be assemblies of pairs of infrared light emitting diodes and can be Cree LED, incandescent, or Xenon assemblies or any other forms.
Further, other light sources 312 can be disposed within the housing. In particular examples, opposing sets of light sources 312 can be disposed on opposite sides of the axis of symmetry 950. In particular, light sources 312 of the same type can be disposed on opposite sides of the axis of symmetry 950. Optionally, the housing 302 can include a power supply.
In a further example,
As illustrated, the rail mounting system 1200 includes three powered rails 1202. In general, the rail mounting system 1200 can include at least one powered rail 1202, such as at least two powered rails 1202, at least three powered rails 1202, or four or more powered rails 1202. Generally, the mounting system 1200 does not include greater than 10 powered rails.
The powered rails 1202 can have a Picatinny configuration. In another example, the powered rails can have a KeyMod™ configuration. In an additional example, the powered rails can have an M4 Rail™, LiteRail™, RIS II, or Omega Rail™ configuration, or a combination thereof. In a further example, the powered rails 1202 can have a propriety mounting configuration. While the illustrated embodiments of the rail mounting system 1200 illustrate each of the powered rails 1202 as providing the same mounting configuration, each of the powered rails 1202 can have a different mounting configuration.
The control rail 1204 can have a mounting configuration similar to the mounting configuration of the powered rails 1202. In another example, the control rail 1204 can have a Picatinny configuration. In a further example, the controller 1204 can have a KeyMod configuration. In an additional example, the control rail can have an M4 Rail™, LiteRail™ RIS II, or Omega Rail™ configuration, or a combination thereof. Alternatively, the control rail 1204 can have a proprietary mounting configuration.
The control rail 1204 can provide power to one or more of the plurality of powered rails 1202. In particular, a handle including a power supply or another power supply interfacing with the control rail 1204 can provide power through electrical conduits to each of the plurality of powered rails 1202. In a particular example, the control interface of the control rail 1204 can allow for selectively providing power to select individual powered rails 1202 without providing power to the other powered rails. As such, one or more of the powered rails 1202 can operate and be provided power independently.
Further, the system allows for different voltages in different wave patterns to be provided to select individual powered rails 1202. For example, a power supply interfacing with the control rail 1204 can provide a first voltage or first waveform to one of the power rails 1202 operating a different voltage or a different waveform than another of the powered rails 1202. In particular, depending on the power supply, voltages of 1.5 V, 3V, 6V or 9V can be provided to select rails of the plurality of powered rails. Further, different waveforms can be provided to a powered rail, such as a constant, a square waveform, a sinusoidal waveform, a saw tooth waveform, or a combination thereof.
In a particular example, the electrical conduits can extend from the control rail 1204 to the individual powered rails 1202 through a rim structure 1206 that extends around the circumference of the support 1210. For example, the rim 1206 can extend along a leading-edge or a back edge of the support 1210. In an alternative example, the rim structure 1206 can extend around the support 1210 at a position between the front and back of the support 1210.
When viewed in cross-section, as illustrated in
As illustrated, the control rail 1204 resides in a bottom position of the support 1210, while three powered rails 1202 are distributed with offsets of 90° from each other around the circumference of the support 1210. The rim 1206, which can house the electrical conduits from a control rail 1204 to the powered rails 1202, can extend around the circumference of the housing 1204 either at a front edge of the support 1210 or a back edge of the housing support 1210.
While
Below the ridge 1508 is a side surface 1510 disposed on each side of the rail 1500. At each of the attachment positions, the powered rail 1500 can include power access points 1512. The power access points supply power or access to ground. In a particular example, access points 1510 to a common electrical conduit can be provided on one side 1510 of the powered rail 1500, and access points to a separate electrical conduit, for example, a power supply or ground, can be provided on an opposite side of the powered rail 1500.
When not in use, a strip of insulator 1514 can be supplied to cover unused access points 1510. Optionally, the strip 1514 can include raised nodules 1516 that fit within the access points 1512.
When viewed in cross-section, as illustrated in
In a particular example, the access points 1606 or 1610 can be openings providing access to the rails 1604 or 1608 respectively. The openings can have a characteristic diameter defined as the square root of the cross-sectional area divided by pi (i.e., sqrt(A/pi)) of 0.15 mm to 2 mm, such as 0.25 mm to 1.5 mm or 0.5 mm to 1.25 mm. The openings 1606 or 1610 can have a depth of 0.15 mm to 6 mm, such as 0.15 mm to 3 mm or 0.5 mm to 2 mm. The openings 1606 or 1610, can have a circular cross-section. In another example, the openings 1606 or 1610 can have a cross-section of a polygonal shape, such as a triangle, a rectangle, a hexagon, or an octagon. In particular, the shape and diameter can be configured to limit water incursion into the opening based on surface tension at an air/water interface at the opening. Such exclusion of water can prevent unwanted current generation along the firearm and limit corrosion.
The control rail can include a plurality of attachment points. At the attachment points, the control rail can also include a control interface to provide electrical interaction between the control rail and the powered rails. For example, as illustrated in
For example, the control interface 1702 can include a plurality of access points having a characteristic diameter of 0.15 mm to 2 mm, such as 0.25 mm to 1.5 mm or 0.5 mm to 1.25 mm. In a further example, the control interface access points can have a depth of 0.15 mm to 6 mm, such as 0.15 mm to 3 mm or 0.5 mm to 2 mm. Further, the control interface access points can have a circular cross-section. In another example, the control interface access points can have a cross-section of a polygonal shape, such as a triangle, a rectangle, a hexagon, or an octagon. In particular, the shape and diameter can be configured to limit water incursion into the opening based on surface tension at an air/water interface at the opening. Such exclusion of water can prevent unwanted current generation along the firearm and limit corrosion.
In an example, the interface 1712 can provide electrical interaction with a plurality of electrical conduits 1716 extending through the control rail 1700. For example, the interface 1712 is illustrated as being disposed on a top surface of the rail 1700 and the plurality of electrical contacts 1716 extend horizontally along the rail 1700 under the surface 1706. Alternatively, the control interface 1712 can be disposed on the top surface 1704.
Optionally, the control rail 1700 has a ridge 1708 around which the control attachments can be secured. Under the ridge 1708, the control rail 1700 includes a side surface 1710. Optionally, along the side surface 1710 at one or more of the attachment points 1702 are additional access points 1714. Such access points 1714 can be used to provide power to additional accessories attached to the control rail instead of the powered rails. Alternatively, the access points 1714 can provide access to a common electrical conduit. In an example, the access points 1714 provide connection to a select conduit 1718 extending along or under the surface of side surface 1710. For example, the conduit 1718 can extend in a manner similar to the rails 1604 or 1608 illustrated in
In an alternative example, the control interface 1712 can be provided on one or both of the side surfaces of the control rail 1700. In such an example, multiple access points can be provided at each of one or more of the attachment positions 1702 along the side surfaces 1710 the control rail 1700.
A power supply or control device can be connected to the control rail and electrically access the control interface. In a particular example, a handle that includes a power supply and control circuitry to control the control interface can be connected to the control rail. For example, as illustrated in
An exemplary handle 1900 includes an electronic interface, such as a mode select button 1908 and an activation button 1910. Optionally, the buttons (1908 and 1910) can be counter sunk. In another example, an additional activation button can be included on an opposite side of the handle 1900 as the mode select button 1908. In operation, the mode select button 1908 can be toggled between different modes providing power to select rails depending on the functionality of the mode select button 1908, and the activation button 1910 can be depressed to implement the mode selected using the mode select button 1908. Optionally, the handle 1900 can have an additional activation button positioned on the same side of the handle 1900 as the mode select button 1908 or on the opposite side of the handle of the mode select button 1908. In particular, the additional activation button can activate a different device than the activation button 1910. For example, the activation button 1910 can activate light devices based on the mode selected through the mode select button 1908, whereas the additional activation button can activate a different type of device or a device having significant consequences, such as a Taser device, for example, in response to selection of a Taser mode using the mode select button 1908. An exemplary handle can further include a front multi-pin electrical interface 1912 to provide a wired connection to a head mounted device that includes a plurality of light sources. In an example, the buttons can be counter sunk to prevent accidental activation.
In addition, the handle 1900 can include a programming or recharging interface 1914 that can access an external power supply or a computational device. For example, the computational device can be used to program the modes selectable using the mode select button 1908. In another example, the electrical interface 1914 can provide for recharging a power supply of the handle 1900. For example, the interface 1914 can allow for interaction with a battery, line power, solar power, or other power supply, or any combination thereof, to recharge or provide power to the handle 1900.
In a particular example, a lower surface of the handle 1902 configured to interface with the palm of the hand is disposed at an angle α relative to a horizontal plane of the rail to which the handle is attached. A select range of angles also provides for desirable positioning of the hand and activation of different muscle groups within the arm and can be selected to provide improved muscle control, recoil control, or reduce fatigue. In an example, the angle α is in a range of 5° to 60°, such as a range of 10° to 60°, a range of 10° to 45°, a range of 15° to 35°, or a range of 18° to 30°.
As illustrated in
In a particular example, the handle provides multiple contact surfaces which provide for improved control of the firearm using the leading hand and arm. For example, as illustrated in
The thumb contact 2118 can provide an upper surface onto which the thumb rests and can extend out from the body 2102 to define a protected recess that prevents the thumb from being readily struck from the side. The thumb contact 2118 can include a lower surface 2126 onto which a side of the thumb or the tip of the thumb rests and can optionally define a stop surface 2124 to be contacted by the tip of the thumb to signal positioning of the thumb or hand or to prevent access to the thumb from a forward position. In a particular example, the thumb contact 2118 can be placed at an angle δ relative to a horizontal place of the rail in a range of 0° to 45°, such as a range of 0° to 40°, a range of 5° to 40°, a range of 10° to 35°, a range of 10° to 30°, or a range of 20° to 30°.
In another embodiment illustrated in
As illustrated in
While not illustrated, one or more signaling mechanisms can be utilized to indicate which mode is selected. For example, one or more LEDs can be disposed on the backside of the handle. Alternatively, a vibrational signal can be used. In another example, a sonic signal can be used to indicate the mode. In a particular configuration including an ordered set of modes, a single LED disposed at the back of the handle can blink a number of times to indicate which mode is selected. In another example, the handle can vibrate upon selection of the mode to indicate which mode is selected. In a further example, when a particular mode is selected, a sonic signal, such as an alarm, can sound from within the handle.
The handle can also include a multi-pin front interface 2430, such as a wired interface, to interact with a head device having multiple light sources or other attached devices. In a particular example, the multi-pin interface 2430 can be waterproof or water tight. Alternatively, the handle can be configured with an attachment point to or can be integrated with a structural extension to couple with a head device. In a particular example, the handle, extension, and head can be formed as a unitary piece, or in one or more sections.
In particular, the location of the buttons and the contact surfaces of the handle can provide for binary mechanical action. Such binary mechanical action leads a user to disassociate actions by a forward hand from actions of the trigger hand and particularly the trigger finger, preventing accidental discharge of the weapon in stressful situations. In a particular example, a user twists the forward hand at least 10° (e.g., at least 15°), but generally not greater than 60°, from a grip position to access the buttons.
On either side or both, the handle body 3402 can include guide interfaces 3416 to receive a pressure pad keeper 3418. In the case of both sides including the guide interface 3416, an additional panel 3420 can be included that does not have pressure pad keeper features. Optionally, a backplate 3422 can be applied to further secure the pressure pad keeper 3418 or panel 3420 within the guide interface 3416. Optionally, the handle body 3402 can be hollow and the backplate 3422 can secure items within the hollow body 3402 of the handle 3400. In an example illustrated in
For example, in an alternative example illustrated in
In a further exemplary embodiment illustrated in
One or more thumb paddles 5006 can extend from sides of the body 5002. In an example, thumb paddles 5006 can include posts that engage openings 5022 within the body 5002. For example, a thumb paddle 5006 can selectively engage an opening 5002 at one or more positions along the body 5002. The handle 5000 can include a single thumb paddle 5006 or, as illustrated, can include two thumb paddles 5006 extending from opposite sides of the body 5002. In a further example, the thumb paddle 5006 can be rotatable, for example, along an axis of the post that engages the openings 5022.
The body 5002 can further define an index finger grip surface 5008. The index finger grip surface 5008 can optionally be movable between one or more select positions. The index finger grip surface 5008 can be separated by a ridge 5010 from the rearward and downward extending grip post 5012.
The grip post 5012 can include a lower grip surface 5014 and one or more upper grip surfaces 5016 to engage the palm or one or more additional fingers of the hand. The grip post 5012 can include a barrier structure 5020 extending downward from a distal end of the grip post 5012. The barrier structure 5020 can engage the rearward surface of a finger engaging the grip post 5012.
The handle 5000 can include electronic interfaces, such as buttons, activators, or pressure pads. In an example, the electronic interfaces can be disposed on a top surface of the grip post 5012. As illustrated, a pressure pad activator 5018 is disposed on the top surface of the grip post 5012. Alternatively, one or more buttons, such as mode select or activator buttons can be disposed on the top surface of the grip post 5012. Further, the grip post 5012 includes an opening to receive electronics or other tools and devices. The opening can be secured or closed using an end cap or cover plate 5224.
An exemplary thumb paddle is illustrated in
In an exemplary embodiment, the index finger grip can be adjustable to extend outward from the body or be drawn into the body of the handle, depending upon the user's preference. In an example, an insert 5502 can define a front surface 5504 to receive an index finger. One or more positioning posts 5506 or 5508 can extend into the body of the handle and can be secured in place at selective positions based on openings 5510 to receive a locking bolt, pin or screw.
An exemplary cover plate 5602 to cover a distal end of the grip post is illustrated in
As illustrated in
In use, the handle or grip permits positioning of the thumb, index finger, and remaining fingers at positions advantageous for controlling and manipulating a firearm. In particular, the thumb can be positioned approximately parallel with the barrel and positioned under or below the barrel in relative height. Further, the positioning of the thumb paddle in relation to the handguard places the thumb in a recess defined between the thumb paddle and a lower surface of the handguard or rail system. Such positioning of the thumb provides advantageous protection for the thumb and further control of the barrel position. The positioning of the index finger and the remaining fingers of the hand allow the arm to be in an approximately neutral, although partially supinated position. Together, the grip permits a greater range of motion left and right when aiming the firearm, better control of the firearm using the less dominant hand, and manipulation of the firearm using the less dominant hand without maintaining contact with the more dominant hand. In particular, the three points of compression in the described configuration proves control of dragging weight and barrel curl and is particularly useful for controlling muzzle rise of the firearm when in use by a weaker individual or child. As such, the handle or grip provides for greater safety. Further, the less dominant hand can rotate the weapon and provide control of the weapon during a dominant hand magazine change. Embodiments including adjustable or rotatable thumb paddles provide for improved handling of the weapon at different firing speeds. Further, control by the less dominant hand can free the more dominant hand during hand-to-hand combat or allow quick switching between lethal and nonlethal force when approach by an assailant. The low-profile of the handle along the sides provides less loss of peripheral vision, fewer blind spots and limits the risk of the handle catching on a corner or an article of clothing or strap.
The handle, when connected to a powered rail system, can control auxiliary devices attached to a powered rail or optionally to a control rail. For example, as illustrated in
In an alternative example, an interface 3008 can interface with a separate rail attachment interface 3012 that can attach to an access point of the rail. For example, pins 3014 can couple with the access points on the sides of the powered rail to provide power through the wired connection 3010 to the interface 3008 and circuitry 3004.
To modify existing auxiliary devices for use with the rail mounting system, an adapter can be provided which replaces power supplies or batteries of rail mounted auxiliary devices with an adapter that draws power from the powered rail system. For example, as illustrated in
In addition, one or more seals 3110 can be disposed along the structure 3104 to provide a water-tight seal or to provide spacing between the structure 3104 and side walls of the cavity of the auxiliary device into which the power supply was previously inserted. A rear connector 3112 can provide for a tight seal to the back of the auxiliary device and optionally replace a cap or plates, providing watertight seals to the power supply compartment of the auxiliary device. In an alternative example, a kit can be provided to adapt an existing cap or backplate to receive the structure 3104 and associated wiring (e.g., wire 3114).
An interface 3116 includes pins to attach to access points of the powered rail. The pins can provide power through the electrical conduit or wire 3114 to the adapter 3102, which provides power to the auxiliary device.
In a particular example, the rail mounting system can be utilized to control a variety of auxiliary devices connected to the rail, a head device disposed at a front position of the firearm, or one or more additional devices attached to the head device. Controls disposed on the handle can be utilized to select which devices to activate and deactivate, as well as provide power to the devices. In an example, the handle can include control circuitry that is programmable to include different modes in a selectable order.
For example, as illustrated in
In a particular example, the handle 3206 includes a control circuitry 3214 and a power supply 3216. The control circuitry 3214 can interface with a power supply 3216. Depending upon the mode selected, the control circuitry 3214 can provide power through one or more interfaces 3216, 3208 or 3220 to control auxiliary devices or head devices. For example, a mode select button 3218 and an activation button 3210 can be electronically connected to the control circuitry 3214. Activation of the mode select button 3218 can permit the control circuitry 3214 to toggle between modes, and selection of the activation button 3210 can result in implementation of the selected mode through the control circuitry 3214, providing power in a particular configuration and waveform through interfaces 3216 or 3208 to the powered rail 3202 or the head device 3204, respectively.
In a particular example, the control circuitry 3214 is programmable through interface 3220. For example, computational device 3212 can access the control circuitry 3214 through the interface 3220 to provide programming to the control circuitry 3214. In particular, the computational device 3212 can provide a variety of mode configurations and a programmed order of modes to the control circuitry 3214, as well as a type of signal to use in signaling the transition between modes, such as using lights, vibration, or sound. In another example, the computational circuitry 3212 can access the control circuitry 3214 to access data stored with the control circuitry 3214 or on auxiliary devices. For example, a camera mounted to the powered rail system 3202 or the head device 3204 can provide picture or video data through the control circuitry 3214 to the computational circuitry 3212 via the interface 3220.
Alternatively or in addition, the handle 3206 can include a wireless communication circuitry 3224 in communication with the control circuitry 3214. The wireless communication circuitry 3224 can provide for wireless communication with the computational device 3212 or other devices. In an example, the wireless communication circuitry 3224 can be configured to communicate over telecommunications bands in accord with a communications protocol or based on a proprietary protocol. For example, the communication circuitry 3224 can be configured to interact with 802.11x compliant networks. In particular, the communication circuitry 3224 can access Bluetooth™ or Wi-Fi networks. In an additional example, the communication circuitry can communicate with GPS systems, satellite uplinks, cellular networks, or other communications systems. In a particular example, the communication circuitry 3224 can communicate with devices associated with the head device 3204.
Optionally, power can be provided through the interface 3220 either from or to the power supply 3216 via the control circuitry 3214. For example, an external power source can be used to recharge the power supply 3216 through the interface 3220. In an alternative example, an external device can be powered by the power supply 3216 utilizing the control circuitry 3214 and the interface 3220. For example, a handheld device, such as a mobile phone, mobile radio, GPS locators, or camera, can optionally be powered from the power supply 3216.
The control circuitry 3214 can further provide a signal indicating a level of power available in the power supply 3216. For example, the control circuitry can illuminate a light emitting diode (LED) in the back of the handle to indicate when power supply is low or providing an indication of the level of power available from the power supply 3216.
For example, as illustrated in
As illustrated at 3304, the computational device can provide modes to the control circuitry of the handle. For example, the computational device can provide an ordered set of power settings to be utilized by the control circuitry of the handle in response to application of the mode select button. Each power setting can include a power configuration, such as a voltage and waveform, to be provided to a select rail, as well as optionally providing for a time period over which the power settings are to be supplied to the rail. In another example, a power setting included within the ordered set can include power settings for light sources or devices disposed on the head device.
In addition, the programming can include an indication of how users are to be signal once a select mode is selected. For example, the programming can include an indication of LED signals to be displayed to the user, vibrational settings, or alarms that can be activated in response to selection of a particular mode within the ordered set of power settings.
As illustrated at 3306, a user can select a mode by activating the mode select button. Optionally, the control circuitry can notify the user of the selected mode and the user can toggle through modes by repeatedly selecting the mode select button. Once the user has selected a mode, the user can then activate the select mode, as illustrated at 3308, via application of the activate button. In response to application of the activate button, the control circuitry can implement the select mode, for example, power can be supplied to a select rail for a select period of time.
