DETAILED DESCRIPTION

[0143] Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this disclosure. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.

[0144] As described in detail below, various embodiments of the present disclosure include novel folding knife designs and configurations, comprising a sealed power storage device and charge component and/or other features or devices. The present disclosure has significant benefits across a broad spectrum of endeavors.

[0145] Referring now to FIGS. 1A and 1B, front perspective views of a folding knife 2 in a closed position and an open position, respectively, are provided. The folding knife 2 generally has a handle 22 and a blade 6 that rotates relative to the handle 22 between the closed position and the open position. As shown, the blade 6 has a spine 10, a cutting edge 54, and a tip 50 positioned at a distal end of the blade 6 between the spine 10 and the cutting edge 54. The blade 6 can have further features such as a thumb traction surface 14 and a choil 58 that provide enhanced grip surfaces for a user. The blade 6 also has an aperture 18. A user can rotate the blade 6 about a fixed pivot pin 30 from the closed position to the open position. The blade 6 is typically metal, but can be any known material such as ceramic, fiberglass, or plastic.

[0146] The handle 22 has a first scale 26 and a second scale 66, which is better shown in FIG. 2. The handle 22 also has a lock device 34 that can selectively lock the blade 6 in one or both of the open position and the closed position. The handle 22 further comprises a lanyard aperture 38 through both scales 26, 66 where a user can connect a lanyard or other similar device to carry or secure the folding knife 2. The handle 22 and scales 26, 66 can be composed of various materials known in the art, for example, wood, metal, composite material, fiberglass, plastic, etc. The scales 26, 66 can be made of a material that promotes the wireless charging of the folding knife 2. In one embodiment, the scales 26, 66 are made from a plastic that allows an electromagnetic wave to reach electronic components within the scales 22, 66. In other embodiments, the scales 22, 66 can comprise a shield that prevents the free transmission of electromagnetic waves except for the electronic components related to the wireless transmission of electrical energy.

[0147] In one embodiment, a first light or bulb 42a and a second light or bulb 42b are positioned at a forward end of the handle 22, and an activation device 46 such as a button can activate the lights or bulbs 42a, 42b. The lights 42a, 42b illuminate the area (e.g., a portion of an external environment surrounding the handle 22 and/or in which the handle 22 is positioned) in front of the folding knife 2 to assist with a cutting or thrusting action of the blade 6. Pressing the activation device 46 can cause the lights 42a, 42b to illuminate in different ways and in different combinations. For instance, pressing the activation device 46 can cycle the lights 42a, 42b through multiple modes of operation, which can include activating only one light 42a, 42b, activating both lights 42a, 42b, activating one or both lights 42a, 42b with different colors, pulsing one or both lights 42a, 42b to produce a strobe effect, activating one or both lights 42a, 42b with a brighter or less bright intensity, etc. In addition, holding the activation device 46 for a predetermined amount of time (e.g., 1 s, 2 s, 3 s, etc.) can cause the lights 42a, 42b to activate in a yet a further or alternative mode or modes of operation.

[0148] It will be appreciated that while two lights or bulbs 42a, 42b are depicted, embodiments of the present disclosure encompass a greater or fewer number of lights or bulbs 42a, 42b or other devices. In addition, one light 42a can be positioned on one scale and the other light 42b can be positioned on the other scale. One light 42a can emit, for example, a red light, and one light 42b can emit, for example, a white light. Moreover, embodiments of the present disclosure encompass other devices and features such as a light, a locking mechanism, an opening mechanism, a microphone, an audio speaker, a GPS beacon or device, an altimeter, a compass, environment sensors (e.g., barometers, thermometers, hygrometers, air quality sensors including oxygen level, carbon dioxide level, carbon monoxide level, smoke, or the like), a fitness tracker, a heart monitor, a blood sugar monitor, a transmitter, a receiver, a transceiver, a pH sensor, a position sensor, a hand warmer, a vibrating mechanism, a camera or video recorder, a communication device, a clock, a data storage device with an interface such as USB, memory card, or other flash drive medium, and a data storage device managed or interfaced through a wireless data protocol, etc. In embodiments that comprise a USB interface, the data storage device can be stored in one of the cavities defined by the handle, and a USB receptable (e.g., USB 1.0, USB 1.1, USB 2.0, USB 3.0, USB-C, or the like) and/or plug (e.g., including, but not limited to, a magnetic connector or a non-magnetic connector) can be positioned at a surface of the handle. In addition, the data storage device with the USB interface may be removable from or insertable into the handle. In embodiments that comprise a memory card, the handle 22 may include a memory card slot leading to a memory card receptacle configured to receive a secure digital (SD) memory card, microSD card, or other flash drive medium. In embodiments that comprise a data storage device managed through wireless protocol, the data storage device may be configured for any known data transmitting and receiving protocol known in the art. In one non-limiting example, the protocol may be any wireless data protocol usable with handheld devices including, but not limited to, Bluetooth. Moreover, embodiments of the present disclosure can include rubber covers that protect the receptable and/or plug to preserve the air and/or fluid seal within the handle. It will be further appreciated that the activation device 46 can be a button, a switch, a slider switch that moves between more than two positions, a touch screen with pressure sensors, a fingerprint sensor, a microphone that receives voice commands, etc.

[0149] In some embodiments, the plug or other receptacle may be usable for charging, for dispersing or providing power to external devices (e.g., is operable as a powerbank), and/or for data transmitting or receiving by devices within the handle 22, allowing a user to operate, command, and/or otherwise interact with or store data to and/or from an external accessory. For example, a data storage device within the handle 22 may be accessible via the plug or other receptable. By way of another example, devices including, but not limited to, a GPS beacon or device, an altimeter, a compass, environment sensors (e.g., barometers, thermometers, hygrometers, air quality sensors including oxygen level, carbon dioxide level, carbon monoxide level, smoke, or the like), a fitness tracker, a heart monitor (e.g., a heart rate and/or pulse rate sensor), a blood sugar monitor (e.g., a blood sugar sensor), a transmitter, a receiver, a transceiver, a pH sensor, a position sensor, a camera or video recorder, or the like may transmit and/or receive data via the plug or other receptacle. It is noted at least some, or all in some embodiments, of the data transmitting and receiving with the handle 22, however, may be completed via wireless communication.

[0150] Referring now to FIG. 2, a rear perspective view of the folding knife 2 is provided. Specifically, the second scale 66 of the handle 22 is shown, and a clip 62 is provided that can secure the folding knife 2 in a pocket, a belt, or other location. The clip can be positioned on either the first scale 26 or the second scale 66. FIG. 2 also shows the reverse side of the blade 6, the lock device 34, and the lanyard aperture 38.

[0151] Referring now to FIG. 3A, a bottom plan view of the handle 22 of the folding knife is provided. The first scale 26 and the second scale 66 define a channel 70 that receives the blade when the blade is in the closed position. In other words, the cutting edge of the blade is positioned in the channel 70 when the blade is in the closed position, and the cutting edge of the blade is position outside of the channel 70 when the blade is in the open position. In this view, the channel 70 has a channel width 74. The blade, the first scale 26, and the second scale 66 have substantially planar shapes to preserve the ergonomics and functionality of the handle 22 and the folding knife 2. Thus, the channel width 74 can be on the order of the thickness of one or both of the first scale 26 and the second scale 66 in some embodiments.

[0152] Referring now to FIG. 3B, a bottom plan view of the handle 22 of a knife or tool is provided. Each scale 26, 66 of the handle 22 has a complete electrical system including at least one light 42b, 42c at a forward end of the scale 26, 66. In addition, each scale 26, 66 has a power storage device, a control unit, a charge component, and an activation device 46a, 46b. In some embodiments, the electrical system in each scale 26, 66 can be completely isolated and independent from each other. In other embodiments, the electrical systems in each scale 26, 66 are connected and operate together for redundancy. Thus, one charge component can charge all power storage devices of all electrical systems in the handle 22, and a given power storage device can power all lights 42b, 42c. In addition, the knife may include the necessary components or circuitry to charge external devices with the power storage devices (e.g., the knife is operable as a powerbank) via a wired connection (e.g., with a plug) or wireless connection (e.g., inductive charging). For example, the external device may include, but is not limited to, a personal electronic device (e.g., a phone, tablet, smartwatch, or the like), rechargeable flashlight, GPS device, or the like.

[0153] As noted above, each scale 26, 66 has an activation device 46a, 46b, and the activation devices 46a, 46b can operate the lights 42b, 42c in a number of ways. For example, in one embodiment, the activation device 46a on the first scale 26 controls the light 42b or plurality of lights 42b on the first scale 26. A user can engage the activation device 46a to cycle through a series of modes of operation for the light 42b or plurality of lights 42b such as: turning on one light 42b, turning on multiple lights 42b, flashing one or more lights 42b, changing the color of the light(s) 42b, 42c, turning off one or more lights 42b, etc. A user can engage the other activation device 46b to cycle through a similar series of modes of operation for the other light 42c or plurality of lights 42c.

[0154] In other embodiments, having each side of the knife or tool with lights and activation devices provides flexibility for a user. For example, the knife or tool may be available only to a particular hand, such that the user may be limited as to which side of activation devices may be used. By way of another example, the knife or tool may be configured for either handedness of the user. By way of another example, a clip or other retaining feature may be positioned across one of the scales 26, 66 and possibly obscuring a light and/or activation device. In some embodiments, the electrical systems are connected and operate with each other, and each activation device 46a, 46b can control both lights 42b, 42c or pluralities of lights 42b, 42c. Engaging one of the activation devices 46a, 46b can cycle through modes of operation such as: turning on one light 42b, 42c, turning on both lights 42b, 42c, turning off one light 42b, 42c, changing the color of the light(s) 42b, 42c, turning off both lights 42b, 42c, etc.

[0155] Regardless of whether the multiple electrical systems are separate or connected, a user can engage each activation device 46a, 46b in different ways such as pressing the activation device 46a, 46b, double-clicking the activation device 46a, 46b, pressing and holding the activation device 46a, 46b, etc. These different ways of engaging the activation device 46a, 46b can be used to manipulate the lights 42a, 42b in different ways. For example, pressing one activation device 46a will cycle through modes of operation for one light 42b or set of lights 42b, and double-clicking the same activation device 46a will cycle through modes of operation for another light 42c or set of lights 42c. Alternatively or in addition, double-clicking the same activation device 46a will cycle through a second set of modes of operation for one light 42b or set of lights 42b. Pressing the activation device 46a, 46b means pressing the activation device 46a, 46b only once in a predetermined time period, double-clicking means pressing an activation device 46a, 46b multiple times within the predetermined time period, and holding the activation device 46a, 46b means pressing and holding the activation device 46a, 46b for longer than the predetermined time period.

[0156] The lights 42b, 42c can also have different colors and can encompass any electromagnetic radiation-emitting device. For instance, in one embodiment, one light 42b or set of lights 42b emits white light and the other light 42c or set of lights 42c emits red light, and one activation device 46a is operably connected to only one light 42b or set of lights 42b and another activation device 46b is operably connected to only the other light 42c or set of lights 42c. In a further embodiment, both lights 42b, 42c or sets of lights 42b, 42c are one color, such as white, and each activation device 46a, 46c is operably connected to all lights 42b, 42c for redundancy. Further still, embodiments can incorporate infrared lights and/or any device that emits electromagnetic radiation such as lasers.

[0157] It will be appreciated that while the lights 42b, 42c are depicted at a forward end of the handle 22, the lights 42b, 42c can be located at any positioned on the handle 22 and/or can include a plurality of lights that form a screen on an outer surface of the handle 22.

[0158] Referring now to FIG. 3C, a bottom plan view of a knife with a handle 22 and with a blade 6 is provided. In this embodiment, the knife is a fixed blade knife and the handle 22 does not have a channel to receive a rotating blade. Instead, the handle 22 can be made from a solid material or even from multiple scales joined together without a channel. The handle 22 in FIG. 3C has a light 42b, 42c or sets of lights 42b, 42c on each side of the blade 6, and the lights 42b, 42c are operable with the activation devices 46a, 46b as described above with respect to FIG. 3B. While knives are depicted in the figures, embodiments of the present disclosure can apply to any tool.

[0159] Referring now to FIGS. 4A and 4B, a rear elevation view and a perspective view of an inner surface of the first scale 26 are provided, respectively. A power storage device, a charge component, an activation device, and a device such as a light are arranged in the first scale 26. Corresponding cavities, recesses, and channels extend into the inner surface of the first scale 26 to provide space for these components but are also strategically chosen to leave a remaining reinforcement area 82 that provides strength and stiffness to the first scale 26 and the folding knife.

[0160] Two storage cavities 78a, 78b extend into the first scale 26 to receive power storage devices, which can be batteries with planar shapes, e.g., disks or flat cylinders. Instead of a single battery with a thickness that is too large for the first scale 26, two or more separate batteries can each have a smaller thickness that allows for the batteries to be positioned in the first scale 26 while maintaining the planar ergonomics of the scale 26 and the folding knife. It will be appreciated that the power storage device can be a capacitor or other storage devices and, in addition, the folding knife can have a single storage cavity 78, more than two storage cavities 78, or even a combined cavity in various embodiments. FIG. 4B shows arms 118a, 118b that at least partially extend over an area of the respective storage cavities 78a, 78b. The arms 118a, 118b help retain the batteries inserted into the cavities 78a, 78b and can deflect as the batteries are positioned in place in the cavities 78a, 78b. When a liner, a backspacer, a second scale or other component is secured over the inner surface of the first scale 26, the arms 118a, 118b can effectively lock the power storage devices in the cavities 78a, 78b. Moreover, the arms 118a, 118b can have electric contacts to transfer power between the power storage devices and other components within the handle. In this regard, the power storage devices may be batteries, capacitors, or the like and/or can be either integrated into the knife or removable from the knife. For example, the power storage devices may be charged when installed in the knife (e.g., as rechargeable batteries or capacitors), either via wired connection (e.g., a plug) or via wireless or remote connection (e.g., inductive charging). By way of another example, the power storage devices may be removable and charged remotely with a cradle or other battery charger. By way of another example, the power storage devices may be replaceable, such as a one-time-use battery configured to fit within and make contact with leads in a defined cavity.

[0161] Next, a control cavity 90 extends into the inner surface of the first scale 26 to receive a control unit such as a circuit board as well as a charge component such as an inductive coil, a resonator coil, or an RF antenna. In some embodiments, the storage cavity 78 and the control cavity 90 can be combined into a single cavity. Also shown in FIG. 4A are three activation apertures 110a, 110b, 110c that extend through the first scale 26. These apertures 110a, 110b, 110c allow a portion of the activation device to extend between the outer and inner surfaces of the first scale 26 to send a signal to other components within the folding knife. The three apertures 110a, 110b, 110c are arranged below the activation device so that if the activation device is pressed asymmetrically, then at least one part of the device will register the pressing action and transmit a signal through one of the apertures 110a, 110b, 110c. Two recesses 102a, 102b are positioned at the forward end of the first scale 26, and these recesses 102a, 102b receive the two lights 42a, 42b shown in FIGS. 1A and 1B, or other devices in other embodiments.

[0162] Several other recesses and apertures are shown in FIG. 4A. A pivot recess 98 receives part of the blade, typically the tang of the blade, and is centered about the pivot point 30 of the blade. A lock aperture 94 extends through the first scale 26 to receive components of the locking device. The lanyard aperture 38 is also depicted.

[0163] Several channels extend into the inner surface of the first scale 26 to link the various components of the folding knife together, and the channels are strategically located to leave the remaining reinforcement area 82 that provides strength and stiffness to the first scale 26 and the folding knife. A first storage channel 86a extends between the control cavity 90 to the first storage cavity 78a, a second storage channel 86b extends between the two storage cavities 78a, 78b, and a third storage channel 86c extends from the second storage cavity 78b to the control cavity 90. These channels 86a, 86b, 86c can route wires, electric contacts, or otherwise provide electrical communication between the power storage devices and the control unit and/or charge component.

[0164] Three activation channels 114a, 114b, 114c extend from respective activation apertures 110a, 110b, 110c to the control cavity 90 to route wires, electric contacts, or otherwise provide electrical communication between the activation device and the control unit and/or charge component. Two device or light channels 106a, 106b extend from respective recesses 102a, 102b to the control cavity 90 to route wires, electric contacts, or otherwise provide electrical communication between a device such as a light and the control unit and/or charge component.

[0165] The first light channel 106a extends between the lock aperture 94 and a top edge of the inner surface to leave the remaining reinforcement area 82 on either side of the first light channel 106a. Two activation channels 114a, 114b merge together, but a remaining reinforcement area 82 is positioned between the merged channels 114a, 114b and the first light channel 106a. Likewise, the second light channel 106b and the third activation channel 114c merge together but leave a remaining reinforcement area 82 on either side of the merged channel. These reinforcement areas 82 provide stiffness and strength to the first scale 26 much like a reinforcing rib as described below with respect to the second scale 66 shown in FIGS. 5A and 5B.

[0166] Referring now to FIGS. 5A and 5B, a front elevation view and a perspective view of an inner surface of the second scale 66 are provided, respectively. Like the first scale, the second scale 66 also has a lanyard aperture 38 and a pivot recess 98 at the forward end where the blade is located, specifically the tang of the blade. The second scale 66 also has a back portion (also called a “back spacer” or “backspacer”) 130 that establishes the width of the channel between the scales in this embodiment. Also shown in FIGS. 5A and 5B are the system of cutout areas 126 and ribs 122. The cutout areas 126 remove weight and mass from the second scale 66 and the remaining ribs 122 provide stiffness and strength to the second scale 66. In general terms, the cutout areas 126 can correspond to the cavities, recesses, and channels like the first scale, and the ribs 122 can correspond to the reinforcement area of the first scale. However, the cutout areas 126 and ribs 122 in the second scale 66 are more optimized to maximize the cutout areas 126 and minimize the area of the ribs 122 since the components and wires are not housed in the second scale 66 in this embodiment. In other words, the cavities, recesses, and channels in the first scale must accommodate the sizes and shapes of the various components before optimizing to reduce mass and maintain strength and stiffness. This difference between the first scale and the second scale is further shown by the combined area of the cutout areas 126 in the second scale 66 being greater than the combined area of the cavities, recesses, and channels of the first scale. Conversely, the combined area of the ribs 122 is smaller than the reinforcement areas in the first scale.

[0167] In some embodiments, the second scale 66 can include one or more power storage devices to augment the power storage devices in the first scale. In one exemplary embodiment, the second scale 66 has one or more cavities that receive one or more power storage devices, such as batteries or capacitors. A wire can extend from the power storage devices in the second scale 66 to the electrical components in the first scale to supply and receive power from the electrical components. For instance, the wire can extend to the power storage devices in the first scale such that all power storage devices of the folding knife collectively work together to store power from the charge component. In some embodiments, the power storage devices in the second scale 66 can connect to the control unit or the charge component to serve as a back-up power reserve. In addition, in some embodiments, a backspacer, liner, electrical contacts, etc. operably connect the power storage devices in the second scale 66 to electrical components in the first scale. Alternatively, the backspacer 130 can have a channel through which wires or electrical connectors run from the first scale 26 to the second scale 66. In various embodiments, the second scale 66 itself is a power storage device to completely utilize the mass and space of the second scale 66 for storing power. The power storage device can have the pivot recess 98, the backspacer 130, and the lanyard aperture 38 to function as the second scale 66.

[0168] Referring now to FIG. 5C, a front elevation view of an inner surface of a scale 66 is provided. Specifically, the scale 66 is a second scale 66 that complements a first scale of a handheld tool. Like the embodiment shown in FIGS. 5A and 5B, the scale 66 in FIG. 5C has a pivot point 30, a plurality of ribs 122, and a plurality of cutout areas 126. In addition, one of the cutout areas 126 receives a universal serial bus (USB) drive, which comprises a receptacle for selectively interconnecting to another device and comprises a data storage device for storing information. The receptacle can move between positions where, in a first position, the receptacle is retracted within a volume defined by the scale 66. In a second position, at least a portion of the receptacle extends beyond the scale's volume to selectively interconnect with another device to send and receive data. It will be appreciated that other devices can be received in the cutout areas 126 as described elsewhere herein.

[0169] Referring now to FIGS. 6A and 6B, rear elevation views of the various components of the folding knife are provided. As shown in FIG. 6A, the folding knife has a control unit 138, which is a circuit board in this embodiment, and a charge component 142, which is an inductor coil in this embodiment. Storage wires 146a, 146b, 146c link the power storage devices 134a, 134b to the control unit 138 and charge component 142. When the folding knife is in the presence of another charge component, power can be wirelessly transmitted to the charge component 142, which charges and recharges the power storage devices 134a, 134b. In this embodiment, the power storage devices 134a, 134b are CR1616 batteries that have a thickness of 1.6 mm and a diameter in the planar direction of 10 mm. Therefore, in some embodiments, the ratio of the thickness to the maximum width in the planar direction can be between eight and twelve, or eight, nine, ten, eleven, or twelve. In various embodiments, the ratio is greater than eight. Activation wires 154a, 154b, 154c link the activation device 46 to the control unit 138, and light wires 150a, 150b link the lights 42a, 42b to the control unit 138. In some embodiments, a charge wire can connect to electrical components in the first scale to power the power storage devices 134a, 134b from an external power source. A socket at an outer surface of the first scale can receive a plug to connect the charge wire to the external power source, and a rubber stop can be positioned in the socket when the charge wire is not in use to prevent water, moisture, dirt, or other external elements from penetrating the interior of the first scale.

[0170] FIG. 6B shows the various components positioned in the cavities, recesses, and channels of the first scale 26 of the folding knife. The control unit 138, the charge component 142, and the power storage devices 134a, 134b can be sealed from external elements individually or in a single enclosed volume. The components are sealed to prevent fluid, whether gas or liquid, and dirt from moving between the enclosed volume and outside of the enclosed volume. Sealants, glues, rubber, gaskets, o-rings, epoxies, and other similar materials can provide the desired seal.

[0171] Referring now to FIG. 6C, a further embodiment of electrical components with two electrical systems 155a, 155b is provided. Each electrical system 155a, 155b is the same or similar to other systems described herein, including the system described in FIGS. 6A and 6B. The two electrical systems 155a, 155b are laid open in a common plane in FIG. 6C, but it will be appreciated that the electrical systems 155a, 155b positioned in the handle of a tool would be generally oriented on two planes that are parallel to each other with one electrical system 155a in one plane and the other electrical system 155b in the other plane, either in the same scale or one electrical system 155a in one scale and the second electrical system 155b in the second scale.

[0172] As shown, an indicator light (or lights) 156 and an orientation sensor 157 are each operably connected to the control unit for each electrical system 155a, 155b. The indicator light 156 can emit a light or specific colored light depending on the status of various aspects of the tool such as the quantity or amount of charge of one or more of the power storage devices 134a, 134b, 134c, 134d. For example the indicator light 156 may include a light emitting diode (LED) or other light generation device known in the art.

[0173] The indicator light 156 can be a single light in some embodiments that emits light into an aperture or light pipe (e.g., fiber optic cable, or the like) that extends through the handle such as the lanyard aperture. In some embodiments, the indicator light 156 may be visible through a lens (e.g., fabricated from plastics, sapphire, protective glass, glass with selected focusing, magnifying, reflective, or refractive properties, or the like) positioned proximate to or over the aperture in the handle 22. Thus, light from the indicator light 156 is visible from both sides of the handle. Mounting the indicator light 156 behind a light pipe and/or a lens may allow directed and/or assisted projection of illumination from the indicator light 156. In addition, mounting the indicator light 156 behind a light pipe and/or a lens may allow for remotely housing the lights within the handle 22 to manage component arrangement and spacing within the handle 22, which may result in a better balancing of heat generation throughout the handle 22 while also providing a cleaner, more stylish integration of the light 156 into the handle 22 profile while also protecting the light 156 from exterior elements.

[0174] In general, the folding knife or tool as described throughout the present disclosure may be configured to address heat generation within the handle 22 profile. For example, components that generate heat within the folding knife may be arranged (e.g., spaced, stacked, or the like) to balance or distribute heat generation throughout the folding knife. By way of another example, the folding knife may include components or methods (e.g., heat sinks, airflow apertures or channels, or the like) to remove heat from components (e.g., electronics, lights or bulbs, or the like) within the folding knife, preventing issues of overheating leading to slowed performance or increased rate of component deterioration. By way of another example, the folding knife may include components or methods to direct heat to components (e.g., temperature sensors, heat sinks, etc.) within the folding knife.

[0175] In one embodiment, the indicator light 156 is a dimmable light where the intensity of the light corresponds to the amount of charge in the one or more power storage devices 134a, 134b, 134c, 134d. A brighter light corresponds to more charge. In some embodiments, the indicator light 156 will emit a light with a first intensity that corresponds to a first quantity of charge of the power storage device. Then, the indicator light 156 will emit the light with a lesser second intensity that corresponds to a lesser second quantity of charge of the power storage device. In various embodiments, the indicator light 156 will emit a light with a first color, such as green, that corresponds to a first quantity of charge of the power storage device. Then, the indicator light 156 will emit the light or another light with a second color, such as red, that corresponds to a lesser second quantity of charge of the power storage device. In addition, the indicator light 156 does not need to be constantly emitting light. In one embodiment, an activation device on each side of the handle can be pressed simultaneously, and one or both control units send a signal and power to the indicator light 156 to emit a light that corresponds to the amount of charge in the power storage devices.

[0176] In another embodiment, the indicator light 156 is provided by a light pipe. In some embodiments, the light pipe is positioned proximate to an aperture within the handle 22. For example, the aperture may be a lanyard aperture and the light pipe may form a ring about an inner surface of the lanyard aperture. The light pipe may be configured to illuminate with at least one color. The at least one color may correspond to an operational status of the charge component. For example, the at least one color may include a first color, a second color, and a third color. For instance, the first color may correspond to a first operational status where a stored power level within the power storage device is below a first power level threshold corresponding to a first quantity of charge. In addition, the second color may correspond to a second operational status where the stored power level within the power storage device is above a second power level threshold corresponding to a second quantity of charge. Further, the third color may correspond to a third operational status where the power storage device is receiving power. The third color may correspond to a third stored power level between the first power level threshold and the second power level threshold, where the third stored power level corresponds to a third quantity of charge. In one non-limiting example, the first color may be red, the second color may be green, and the third color may be yellow. In another non-limiting example, the at least one color may blink intermittently at pre-determined time intervals. A lens may be positioned over the aperture, and the at least one light may be visible through the aperture.

[0177] It is noted the above embodiment is illustrative, and that the indicator light 156 may be otherwise configured without departing from the scope of the present disclosure. For example, the indicator light 156 should not be considered as being limiting to 1, 2, 3, or any number of colors. By way of another example, the indicator light 156 should not be considered as being limited to a particular pattern or arrangement of colors corresponding to one or more operational statuses. In this regard, the above embodiment should not be interpreted as limiting the scope of the present disclosure.

[0178] Next, the orientation sensor 157 can detect an orientation of the handle to determine which charge component is downward or below the other charge component and closer to a charge base. The orientation sensor 157 can be one or more accelerometers. When the orientation sensor 157 detects the charge component of the first electrical system 155a is below the charge component of the second electrical system 155b, the orientation sensor 157 can provide a signal to one or both of the control units. Based on the signal, the control unit of the first electrical system can allow the respective charge component to charge the respective power storage device, and/or the control unit of the second electrical system can prevent the respective charge component from charging the respective power storage device. One skilled in the art will appreciate various control units and systems for managing the charging of power storage devices, including those found in U.S. Pat. Nos. 8,022,674; 6,805,090; and 8,305,044, the entire disclosures of which are hereby expressly incorporated by reference in their entireties.

[0179] Referring now to FIGS. 6D and 6E, further views of electronic components and a folding knife are provided, respectively. In FIG. 6D, one embodiment of the present disclosure includes a power storage device 134, a control unit 138, and wires 146a, 146b that connect the power storage device 134 and the control unit 138. Moreover, a charge component 142 that receives energy is operably connected to the control unit 138. As described elsewhere herein, the charge component 142 can receive power in a wireless manner, which the control unit 138 can route to the power storage device 134 to charge the power storage device 134.

[0180] FIG. 6E shows the electronic components positioned in the scale 26 of a folding knife with a blade 6. The electronic components can be positioned in a cavity of the scale 26 and retained by, for example, a deflectable arm 118. The energy stored in the power storage device 134 can be used to power any number of devices. The energy can power any combination of lights, data storage devices, clocks, or any other devices or components described herein and included in or connected to the knife. In addition, the present disclosure encompasses embodiments and tools other than a folding knife.

[0181] The electronic components shown in FIGS. 6D and 6E are not physically connected to an activation device such as a button. Instead, a feature of the device in FIGS. 6D and 6E such as a light can be activated in any number of alternative ways. For example, the device may comprise an accelerometer that activates the light when the device is in a particular orientation or range of orientations. Further still, a Global Positioning System (GPS) receiver or other similar receiver can relay the geographic position of the device to the control unit 138, which can then activate or deactivate the light or other feature when the device is within a geographic area, outside of a geographic area, traveling above or below a threshold speed, etc. In some embodiments, an activation device may be positioned on the handle 22 or underneath a moveable portion of the handle 22, and may be activated by bumping, tapping, or otherwise causing the portion of the handle 22 with the activation device to come into contact with the user or the surrounding environment (e.g., a table surface, a tree, or the like). The device, tool, or knife can include a light sensor that turns on the light when the level of the ambient light is below a certain threshold. In some embodiments, an activation device such as a button or light sensor is wirelessly connected to the control unit 138. Thus, when the button is depressed or the light sensor detects ambient light conditions rising above or falling below a threshold in terms of lumens, the light or other feature is activated or deactivated. This wireless connection also allows the cavity that receives the electronic components such as the power storage device 134, the control unit 138, and the charge component 142 to be hermetically sealed with no wires or structure extending beyond an outer surface of the scale 26 or device.

[0182] While embodiments of the present disclosure depict a charge component 142 that can wirelessly receive power via electric induction, it will be appreciated that the electronic components can receive power in other ways. In some embodiments, a self-winding rotor mechanism can provide power to the power storage device 134 and the control unit 138 rather than, or in addition to, the charge component 142. A rotating pendulum turns a pinion that is connected to a generator that produces electricity that is stored in the power storage device 134.

[0183] Referring now to FIGS. 7A-7D, bottom elevation views of the folding knife 2 positioned on a charge base 158 are provided, where FIGS. 7A-7D are side elevation views of the charge base 158. For example, the bottom surface 160 of the charge base 158 is positioned on a flat surface, like a table, desk, or countertop. The folding knife 2 and/or charge base 158 can have features that improve the performance of the wireless charging and also improve safety when using the charge base 158. In FIG. 7A, the first charge component 142 of the handle 22 of the folding knife and the second charge component 162 of the charge base 158 are depicted, and a protrusion 166 extending from the charge base 158 is positioned in a recess or aperture in the handle 22 to align the charge components 142, 162. The protrusion 166 can extend into, for instance, the lanyard aperture of the handle 22 to align the charge components 142, 162. It will be appreciated that the various features depicted in FIGS. 7A-7D are exemplary, and embodiments of the present disclosure include, for instance, a charge base 158 that does not have safety features or alignment features.

[0184] In FIG. 7B, the second charge component 162 can have a larger length and/or cross-sectional area than the first charge component 142 such that a user does not need to precisely locate the folding knife on the charge base 158 to initiate the charging process. Also shown in FIG. 7B is a position sensor 182 that can detect the position of the blade 6, and more specifically, when the blade 6 is in the closed position within a channel in the handle 22 or when the blade 6 is positioned outside of the handle 22, e.g., in the open and extended position. A shield 186 can be positioned between the first charge component 142 and the position sensor 182 to prevent electromagnetic fields from affecting either of the first charge component 142 or the position sensor 182. The position sensor 182 can serve a variety of functions. For instance, the position sensor 182 can be electrically connected to the control unit, and if the blade 6 is not positioned in the closed position in the handle 22, then the control unit does not transmit power from the first charge component 142 to the power storage devices. The position sensor 182 can be located in a variety of positions in the folding knife 2 and can serve a variety of functions. The position sensor 182 is not limited to the position shown in FIG. 7B. For instance, the position sensor 182 can detect when the blade 6 has moved from the closed position to the open position, and then the position sensor 182 can send a signal to the control unit, which then activates, for instance, a light or a cycle counter that counts the number of opening and closing cycles.

[0185] In FIG. 7C, the shield 186 can extend around one or more sides of the first charge component 142 to both insulate the first charge component 142 from external electromagnetic fields and also protect external components from the wireless transmission of power from the second charge component 162 to the first charge component 142. The shield 186 must have at least one open side or open portion to allow the wireless transmission of power from the second charge component 162 to the first charge component 142. In addition, the shield 186 in this embodiment can prevent the wireless transmission of power until the charge components 142, 162 are precisely aligned over or next to each other, which ensures a more efficient transmission of power. Here, the first charge component 142 is positioned in the first scale 26. However, in some embodiments, the first charge component 142 is positioned in the second scale 66 such that it is closer to the charge base 158 and the second charge component 162.

[0186] In FIG. 7D, the first charge component 142 is offset 190 from the outer surface of the first scale 26 and offset 194 from the outer surface of the second scale 66. Some wireless protocols for the transmission of power have maximum ranges between charge components 142, 162. Thus, in some embodiments, the offsets 190, 194 are less than 5 cm in some embodiments. It will be appreciated that the offsets 190, 194 can be less than the maximum range of a protocol (e.g., 2 cm, etc.). Moreover, it can be advantageous to have the folding knife charge when one scale is positioned against the charge base 158 but not when the other scale is positioned against the charge base 158. Therefore, in some embodiments, the first offset 190 is greater than 2 cm and the second offset 194 is less than 2 cm, or vice versa, when the maximum range of the wireless protocol is 2 cm.

[0187] Referring now to FIG. 7E, a further embodiment of a handle 22 of a tool is provided. Like the handle 22 depicted in FIG. 3B, this handle 22 has lights on either side of the handle 22, i.e., one charge component 142a in the first scale 26 and one charge component 142b in the second scale 66. FIG. 7E shows the handle 22 positioned over a charge base 158 that has a charge component 162. The handle 22 itself has charge components 142a, 142b on opposing sides of the handle 22, an indicator light 156, and an orientation sensor 157. As described above, the indicator light 156 can provide a visual indication of the status of an aspect of the handle 22 or tool such as the amount of charge in one or more power storage devices positioned within the handle 22. A similar description is not repeated here and is instead incorporated by reference.

[0188] As also described above, the orientation sensor 157 can help determine the orientation of the handle 22 and specifically which charge component 142a, 142b is positioned beneath the other and, thus, closer to the charge base 158. This is assuming that the bottom surface 160 of the charge base 158 is positioned on a flat, horizontal surface like a table, desk, or countertop. Accordingly, the orientation sensor 157 helps determine which charge component 142a, 142b is closer to the charge component 162 of the charge base 158 for the most efficient and effective charging of the power storage devices in the handle 22. A control unit in the handle can then allow the handle charge component 142a, 142b positioned closer to the charge base charge component 162 to charge the one or more power storage devices, even power storage devices positioned on an opposing side of the handle 22 and/or in a different electrical system. Simultaneously or in the alternative, the control unit can prevent the charge component 142a, 142b positioned above (in the orientation shown) the other charge component, i.e., farther away from the charge base 158, from charging power storage devices. In some embodiments (not shown), the upper surface 161 of the charge base 158 is not flat and, rather, the upper surface 161 has a profile that matches the curvature of the handle such that the handle 22 aligns and sits in the charge base 158. This further positions the handle 22 in the desired charging position.

[0189] It will be appreciated that the present disclosure encompasses embodiments not specifically depicted in the various figures. For instance, in some embodiments, the handle 22 does not include an orientation sensor 157, and both charge components 142a, 142b are allowed to receive power from the charge component 162 of the charge base 158, to the extent possible. Similarly, in some embodiments, a material is positioned between charge components 142a, 142b to eliminate interference between charge components 142a, 142b while one charge components 142a, 142b is receiving power from the charge component 162 of the charge base 158. The material can form a partial Faraday cage between the charge components 142a, 142b. The charge components 142a, 142a and charge component 162 of the charge base 158 can conform to the Qi standard or any other standard or protocol for the wireless transfer of power.

[0190] The embodiments of FIGS. 7A-7E can also include a magnet in the handle 22 and a magnet in the charge base 158 to properly align the handle 22 with the charge base 158 for efficient charging.

[0191] Referring now to FIG. 8, a flowchart for operation of the charging system is provided. First, the folding knife or tool is positioned 198 over or on the charge base, also called a charge pad or pad. Then, the folding knife can initially 202 receive some power to determine 206, for example by the position sensor, if the blade is safely in the closed position in the handle. In some embodiments, the folding knife can rely on the power storage device to power the position sensor and control unit. If the blade is open, then the folding knife, specifically a control unit, can cease 210 charging the power storage device in the folding knife. In various embodiments, an electronic component of the folding knife sends a signal to the charge base such that the charge base prevents the transmission of power to the folding knife. Then, the folding knife can provide 214 a negative indication of charging. In some embodiments, one of the lights emits a red or orange light, indicating caution because the blade is in the open position. If the position sensor determines 206 that the blade is in the closed position in the handle, then the charge pad can continue 218 charging the power storage device in the folding knife. Moreover, the folding knife can provide 222 a positive indication of charging. In various embodiments, one of the lights emits a green light, indicating that the blade is safely in the closed position. It will be appreciated that the present disclosure encompasses embodiments where charging occurs when the blade is in any position or in a particular position.

[0192] Referring now to FIGS. 9A and 9B, perspective views of a folding knife 224 with a blade 226 and a handle 228 are provided. FIG. 9C shows an exploded view of the components of the folding knife 224 shown in FIGS. 9A and 9B. The folding knife 224 has a blade 226 with a proximal end rotatably connected to scales 250, 264 of a handle. The blade 226 can be connected to the handle 228 by a shaft, pin, or screw 244a and a washer 230a, 230b around the shaft, pin, or screw 244a on either side of the blade 226. In some embodiments, two screws 244a are used to secure the blade 226 to the handle 228. The knife 224 also has two spacers 232a, 232b around the screw 244a on either side of the blade 226 to space the blade 226 apart from the scales 250, 264. For example, the spacers 232a, 232b may be configured to hold in position one or more lights 262a, 262b and/or one or more components of a system that powers the lights 262a, 262b. By way of another example, the spacers 232a, 232b may be configured to engage one or more components of a locking mechanism inserted within the knife 224. Also disposed between the scales 250, 264 of the handle is a back spacer 234. An assembly of a ball holder 236, a ball bearing 238, and a spring 240 are operably connected to the back spacer 234 and the blade 226 to cause the blade 226 to open. The spring 240 can be any bias member with a linear or non-linear response. Also shown in FIG. 9C is a light pipe 256 positioned between the two scales 250, 264 to allow light to emit into a lanyard aperture as described elsewhere herein.

[0193] The assembly of the ball holder 236, the ball bearing 238, and the spring 240 may be desirable to some users, as it provides a tactile feedback or a “feel” to assure the user that the blade 226 has opened or closed. Other types of locking mechanisms may be used with less tactile feedback including, but not limited to, a locking and closure detent, an electrical lock, a magnetic lock, a compression lock, a liner lock, a wedge lock, or other locking mechanism known in the art.

[0194] Next, FIG. 9C shows the system that powers the lights 262a, 262b that are positioned in respective scales 250, 264. An electrode and a power coil 254a, 254b are positioned in respective scales 250, 264 where the coils 254a, 254b can power respective batteries 258a, 258b as described herein. Between batteries 258a, 258b is a substrate 252 that can communicate a signal from a user pressing a button 260a, 260b on either side of the folding knife 224. Via the substrate 252, a signal can be relayed and, with a control device 253, cause the lights 262a, 262b to emit electromagnetic radiation as described herein. Finally, the folding knife 224 can be assembled with screws 244, and a clip 246 can be attached to one of the scales 250, 264.

For example, the knife 2, 224 may be configured to receive signals to activate or deactivate components (e.g., visual or aural output devices), start and/or stop data collection (e.g., with sensors), start and/or stop data receiving or transmission (e.g., via the TX/RX unit 296 including, but not limited to, Bluetooth), or the like.

[0230] The knife 2, 224 may be configured to receive and/or transmit data related to knife ownership, knife registration or support, or other related data. It is contemplated the data may be transmitted to or received from another knife 2b, 224b and/or a program or application (app) run on a computer system or personal electronic device 291 (e.g., including the second user interface 280b). The program or app may be configured to provide a user portal or dashboard for app-based services. In one non-limiting example, the user portal or dashboard may display internal operation data for the knife 2, 224. In another non-limiting example, the user portal or dashboard may display user data (e.g., health data). In another non-limiting example, the user portal or dashboard may display surrounding environment data at the present time (e.g., real-time capture of environment data and/or GPS, or the like) previous times (e.g., historical GPS data, or the like), and/or future occurrences (e.g., weather forecasts, or the like). In another non-limiting example, the user portal or dashboard may display or provide the current ownership, chain of ownership, or registration information to a server. In another non-limiting example, the user portal or dashboard may allow for the submission of a request and provide a communication channel with a third party (e.g., a phone call with a contact, a support representative for assistance with the knife 2, 224, or the like). In another non-limiting example, the user portal or dashboard may display the location of the knife 2, 224 if lost or otherwise misplaced. It is noted the knife 2, 224 may be configured to be usable to locate the computer system or personal electronic device 291 if lost or otherwise misplaced.

[0231] The program or app may provide the knife 2, 224 with information related to the operation of the connected second knife 2b, 224b and/or the computer system or personal electronic device 291 (e.g., including the second user interface 280b) or third-party server running the program or app. For example, the knife 2, 224 may be configured to ring or vibrate when a phone call is received, ring or vibrate when an alarm plays, emit sound when sound is output, or provide other aural, visual, or haptic feedback in synchronicity with (or instead of) the computer system or personal electronic device. By way of another example, the knife 2, 224 may be usable as an electronic tool to lock or unlock the computer system or personal electronic device (e.g., a proximity lock), instead of or in addition to (e.g., two-factor authentication) a pin, swipe pattern, fingerprint, facial recognition, or the like.

[0232] The program or app may provide a user or third party with information related to promotional and advertising services, based on the usage of the knife 2, 224.
