An electronic key fob includes a housing defining a recess, a communication system disposed in the housing and having a transceiver and power source that provides power to the transceiver, at least one button disposed in the housing, a tool disposed in the recess of the housing and moveable between a retracted position and an extended position, and a tool lock mechanism. The button is electrically connected to the transceiver. The tool lock mechanism is configured to move between a lock position in which the tool is locked in the retracted position and an unlock position in which the tool can move between the retracted extended position.

A folding knife and related method include actuating elements for locking or unlocking the blade of the knife. The actuating elements are permanently illuminated or backlit so that the actuating elements are more clearly visible in low light conditions and can therefore be safely operated. Such features for knife applications may provide advantages for particular activities where knives are commonly used, such as for law enforcement and hunting.

A hair weave removal tool includes a handle, an elongated member, a magnifier, and a light source. The elongated member extends from an end of the handle. The elongated member includes an extension extending outwardly therefrom and a guide member located laterally adjacent the extension. The magnifier is pivotably coupled to the handle laterally adjacent the elongated member. The light source is coupled to the handle, and is configured to illuminate an area above the extension.

A system for controlling operation of a power tool. The system includes a handpiece having a power tool, a radio frequency identification (RFID) tag, and a wireless transceiver. The system also includes a power pack having an electric motor driving the power tool. The power pack also includes a wireless transceiver, an RFID reader, and non-transitory computer-readable storage media having computer-executable instructions for pairing the handpiece to the power pack. When executed by at least one processor, the computer-executable instructions cause the at least one processor to: interrogate the RFID tag with the RFID reader; receive an RFID signal from the RFID tag including identifying information for the handpiece; store the unique identifying information for the handpiece at the power pack; and, based on receipt of the unique identifying information, complete wireless pairing of the handpiece to the power pack.

A protective device and a method of transmitting an alert from the device, in which the protective device is handheld and includes a flexible sheath disposed between an upper member and a lower member. When the device is compressed, elongated defensive components protrude through openings in the upper member. In some cases, the upper member also includes protruding portions extending upward from the upper member and/or an arm portion extending outward to a side of the device. A signal alert may be automatically transmitted upon device compression.

The present disclosure provides a switch-actuated multi-tool apparatus. The switch-actuated multi tool apparatus includes one or more cutting tools. In addition, the switch-actuated multi tool apparatus includes a housing module. The housing module encloses the one or more cutting tools in a non-functioning state and the housing module has a grip for holding the switch-actuated multi-tool apparatus when the one or more cutting tools is in a functioning state. Further, the switch-actuated multi tool apparatus includes a switch positioned within or around the housing module. The switch actuates the one or more cutting tools. Furthermore, the switch-actuated multi tool apparatus includes a detachable attachment module positioned anywhere around periphery of the housing module. The detachable attachment module allows one or more accessories to be detachably connected to the switch-actuated multi-tool apparatus.

The present disclosure provides an apparatus for serving one or more purposes. The apparatus includes a case. The case has at least one coupling provision from a plurality of coupling provisions. In addition, the apparatus includes a holder operably coupled at one end of the case. The holder is used for holding at least one of a keychain, a ring, a band, and a bracelet. Further, the apparatus may include a band. The band is placed for holding at least one of a communication device or a hand of a user. Furthermore, the apparatus includes an operating module operable coupled with a mechanism that is positioned inside or around the case to control and operate a holding module. The operating module is positioned on any of face of the case. The holding module has a provision for mounting a plurality of elements for serving the one or more purposes.

An active protection system and method in a portable cutting tool with movable cutting members includes at least: a cutting member stop; a controller/processor triggering the stop upon the detection of a danger condition; a proximal electrode electrically coupled with a tool handle and a distal electrode electrically coupled with the cutting member, to make up an armature of a capacitor, the processing unit feeding an electric output signal into one of the electrodes and detecting an electric input signal on the other electrode. The electric output signal includes different frequencies. A detection unit detecting a complex impedance of the electric input signal at the different frequencies. The processing unit determines a danger condition and causes triggering of the stop based on a value of the magnitude of the complex impedance electric signal and on a phase difference of the impedance electric signal at the different frequencies.

A folding knife is provided with a power storage device that can be charged and recharged by a charge component that wirelessly receives power from a remote source. In some embodiments, the folding knife can have a device that consumes energy such as a light, a camera, a microphone, an audio speaker, etc. The power storage device and the charge component can be positioned in a scale of the handle where the substantially planar shapes of the scale, the power storage device, and the charge component are oriented in a common direction. In some embodiments, the cavities, recesses, and channels in the first scale that house these components and linking wires are strategically positioned to leave a reinforcing area that provides strength and stiffness to the handle. Various features are also described herein that improve safety of the charging system.

Multi-tool devices and methods of customizing multi-tool devices in a web-based ordering system are provided. One embodiment of a multi-tool device includes a plurality of compartments, wherein each compartment is configured to house one or more attached tools, one or more removable tools, and/or one or more storage ports. Each compartment includes a moveable portion that is configured to be moveable with respect to the other portions. The multi-tool device further includes at least one pin configured to connect the plurality of compartments together. Each of the moveable portions of the compartments is configured to move between a storage position and a deployed position. When the moveable portions are arranged in their respective storage positions, an outer surface of the multi-tool device has a disk shape, an ellipsoid shape, a truncated ellipsoid shape, a spheroid shape, a truncated spheroid shape, a sphere shape, a truncated sphere shape, an ovoid shape, or a truncated ovoid shape.
