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: 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: A method of exercising includes positioning a foot of a user onto a pedal of an exercise device. The pedal is pivotably connected to a pair of supports forming a triangular base and has a neutral position relative to a pivot axis of the device. The method includes applying a first force to the pedal to rotate the pedal about the pivot axis in a first direction, toward a first support. The method includes resisting movement of the pedal toward the first support with a resistance mechanism of the device. The method includes applying a second force to the pedal to rotate the pedal about the pivot axis in a second direction, opposite the first direction, toward a second support and away from the first support. The method includes resisting movement of the pedal toward the second support with the resistance mechanism of the device.

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 portable exercise device includes a pedal pivotably connected to a pair of supports. The pedal has a neutral position relative to a pivot axis. The pedal is configured to rotate about the pivot axis in a first direction toward one support and in a second direction, opposite the first direction, toward the other support. The exercise device also includes a resistance mechanism configured to exert a force on the pedal about the pivot axis in a direction opposite to the respective direction of rotation of the pedal about the pivot axis. The device is movable between an open, in-use configuration, where the pedal is disposed in the neutral position to receive a foot of a user and the pair of supports together form a triangular base, and a closed configuration, where the pair of supports are flush against the pedal.
