The present invention discloses a safety devices adapted to prevent workers from going into hazardous environment, such as underground using the faulty safety device. As a safety device, typically embodied as a cap lamp, must be charged prior to each use, the device is adapted to detect when the device is removed from the charger. The device starts to blink continuously when disconnected from the charger. An automated test procedure is completed on the device. The user may also complete a manual portion of the test procedure to make the device usable. When the test procedure is completed successfully, the lamp stops blinking. If the test procedure is not successful, the lamp continues blinking to effectively prevent user from using a faulty device.

A light-emitting system (1000) removably attachable to headgear is provided, which comprises: a form factor (1010) configured to surround a portion of the headgear when the light-emitting system (1000) is removably attached to the headgear for use; a plurality of halo lighting elements (1100) configured to selectively generate at least a partial halo of light that radiates outwardly away from the light-emitting system; and at least one task lighting element (1120) aligned in a direction along a task light axis (1130) that is fixed and oriented downwardly at an oblique angle (α) relative to a transverse plane (TP) of the light-emitting system (1000), the at least one task lighting element (1120) being configured to selectively generate flood task lighting in an area in front of a user.

A ballistic helmet system having an integrated circuit layer electrically coupled to one or more powered devices, where the ballistic helmet is configured to operate and control the powered devices. The ballistic helmet system comprises a base layer configured to retain the circuit layer. The circuit layer comprises one or more circuit substrates, which may be formed of a flexible material capable of withstanding elevated temperatures that may result from the bonding and curing process of the helmet components.

A hard hat with symmetric front and back mounting ridges to support a headlamp is described. The hard hat provides mounting ridges to receive insertion slots of a rigid mounting bracket that fit around the ridges. The rigid mounting bracket includes channels to loop a strap through the channels and support a lamp on the bracket. The strap may include a hook and loop fastener system to enable attachment of a variety of lamps to the rigid support bracket. In this way, the hard hat can support a wide variety of headlamps attached to the rigid mounting bracket without destructive alterations to the hard hat. Clips may be added to the rigid mounting bracket to secure or lock the bracket in place during operation and prevent accidental knocks or jarring of the headlamp.

Implementations of a ballistic helmet having an integrated electronic circuit are provided. An example ballistic helmet includes: a first armor plate attached by a hinge to a first side of the ballistic helmet, the first amor plate is configured and positioned to provide ballistic protection; a second armor plate attached by a hinge to a second side of the ballistic helmet, the second armor plate is configured and positioned to provide ballistic protection; and an integrated electronic circuit configured to operate and power electronic devices conductively coupled thereto.

A light intensity control system in a vehicle enables the head lamp of the vehicle and the display of the instrument cluster to switch between one or more beam position depending on the ambient light intensity directly in the field view of the driver's eye.

Headwear for locating people, such as construction workers, firefighters, mine workers, sandhogs, police officers and military personnel. The headwear is hardhat or helmet that tightly fits on a user's head. The headwear comprised of a LED-light, a built-in WiFi device, and power source. The LED-light provides light to the user. The WiFi device transmits the location of the user.

A bicycle light system has front and rear (white and red) lights with mounting brackets to secure on a bicycle helmet. A battery is contained in the rear light casing, with an electrical cord extending between the front and rear light casings. The front light casing has controls for both front and rear lights, which can include different power levels and preferably a flash mode for the front light. Helmet or headstrap mountings for the front and rear light casings have a quick-release feature enabling the lights to be easily and quickly removed from the helmet or headstrap, such as for recharging. Multiple selectable lights can be included in the front light assembly. In an embodiment, any of a series of different front light assemblies can be plugged into the rear assembly. For marine use appropriate light colors can be provided.

A safety helmet includes an outer shell having a front receptacle disposed on a front side of the outer shell and a rear receptacle disposed on a rear side of the outer shell. A first accessory device having a first mating receptacle formed thereon is releasably mountable onto each of the front receptacle or the rear receptacle of the outer shell, and a second accessory device having a second mating receptacle formed thereon is releasably mountable onto each of the front receptacle or the rear receptacle of the outer shell.

The disclosed device, system, and method may comprise one or more devices for digital personal protective equipment. These devices may be network enabled wearables. A plurality of sensors, data transmission mechanisms, self-illuminating LEDs, and communication mechanisms may be embedded in a suspension or harness in various embodiments. A number of sensors may likewise be provided in a glove or earbud (ear plug). The device may measure various aspects of a wearer's movement and transmit that data over a data connection (such as a wifi or mobile connection) to a server. The server may house project and human resources data, worker and condition information, and materials and supplies data, according to various examples of embodiments. The system may further comprise one or more applications which may interpret the data provided.
