Abstract: Various face shield assemblies for hard hats are described. In one embodiment, the face shield assembly includes a hard hat, a mounting bracket, a face shield, a first pivot arm and a second pivot arm. The first pivot arm and second pivot arm are pivotally coupled to the hard hat and rotate with respect to the mounting bracket and the face shield. The face shield is coupled to the first pivot arm and the second pivot arm. The face shield actuates between stowed and operating positions such that the face shield can avoid objects near a front of the hard hat, such as a bill and/or lamp. In other embodiments the face shield assembly includes an adjustable frame coupled to the face shield and the hard hat. The adjustable frame rotates and/or slides with respect to the hard hat.

Abstract: Various embodiments of a voltage detection device and of related safety systems are provided. In various embodiments, the voltage detection device is configured to couple to safety headwear, such as via the one or more housing(s) of the voltage detection device coupling directly to the safety headwear or the voltage detection device coupling to an adaptor mounted to the hard hat.

Abstract: A protective clothing equipment is provided that is comfortable, stabilizing, and compatible with varying types of surfaces. One embodiment of the protective clothing equipment includes a thigh support, a brace coupled to the thigh support, and padding disposed in front of the knee of the wearer.

Abstract: Various embodiments of an accessory bracket for attaching accessories to protective equipment are shown. The accessory bracket includes a mounting bracket body, a center tab, and one or more cam levers that allow for secure attachment to protective equipment. The accessory bracket is designed to improve attachment and retention of accessories to protective equipment.

Abstract: Various embodiments of a jobsite keep out zone system are provided. The system includes one or more detectors configured to determine when an intruder is within and/or is approaching a protected area. In response to the determination, one or more alarms and/or notifications are generated.

Abstract: One or more devices for coupling lighting elements to safety headwear are described. The devices include an element that emits light, a unit that provides power, and a coupling element to couple the device to safety headwear.

Abstract: Various face shield assemblies for hard hats are described. The face shield assemblies actuate between stowed and operating positions such that the face shield can avoid objects near a front of the hard hat, such as a bill and/or lamp. In various aspects, aspects of the face shield assemblies rotate and/or slide when actuating between the stowed and operating positions.

Abstract: Earmuffs with a joint are provided to create a biased pressure distribution about a perimeter of the cup. The earmuffs may include a pivot joint. The pressure distribution creates a wedging pressure (e.g., on a top edge) on the cups that hold the earmuffs on the user's head, for example, when the user rotates the headband behind the head. The bias pressure is also used to adjust the seal formed between the pad and the user's head. Adjustments to the moment created by separating the joints from the cup's apex enable a user to selectively adjust the seal according to the user's preference. A cam is added to the headband to change the hoop stress distributed at the joints and further adjust the compressive forces generated to hold the earmuffs against the user's head.

Abstract: A universal mounting system for a hard hat is provided that includes front and rear mounting locations and auxiliary ridges on either side. A visor is coupled to the hard hat mounting system in such a way as to provide access with minimal interference from the visor to the equipment attached to the mounting locations and ports in the auxiliary ridges. Various embodiments of visors enable modular designs that incorporate different materials and features of the visor. Parallel stretch zones enable folding and holding opposite brims of the visor. Enclosed elastic areas along the inner sides of visor provide user access to auxiliary ridges. Combinations of various accessories on hard hat and how the accessories work together on the universal mounting system are discussed: such as the interaction between visors, earmuffs, face shields, and lamps.

Abstract: A coupling system for safety headwear is provided. Various embodiments of safety headwear accessories, such as a brim guard, are adjustable to couple to various configurations of safety headwear. The brim guard includes a mechanism to detachably couple accessories, such as a face shield, to the safety headwear.

Abstract: A hard hat and related impact protection layer is shown. The hard hat includes one or more feature to improve support of the impact protection layer and coupling of the hard hat to the user. Various suspension mechanisms for hard hat outer shells and strap systems are described herein.

Abstract: Several non-impact face shields for use in jobsite and/or construction settings are shown and described. Various embodiments describe herein include a cover actuates between a covered positioned, in which the cover is in front of the face of the user, and an open position.

Abstract: A lighting system includes a plurality of light fixtures. Each light fixture includes a sensor for performing a test on the light fixture an generating test data. The light fixtures also include a hardware processor and a radio communication module. The radio communication module can communicate the test data to a mobile computing device or to a node. A diagnostic software application can receive the test data, identify a malfunctioning component, and order a replacement component.
