Apparatus and associated methods for a wound valve assembly provide an annular space extending radially around a central portion of a valve, which valve acts to substantially relieve pressure build up in a thoracic cavity
Embodiments relate generally to methods and systems for monitoring personal protection equipment (PPE) compliance. A method may comprise receiving, by a user identification (ID) module, information from sensor modules attached to PPE devices worn by
Apparatus and associated methods relate to an electrical interface design architecture to independently excite each of a network of light strings and/or light string controllers with any of a number of independent excitation signals. In
Apparatus and associated methods relate to a biased engagement relationship between an end cap and a support base slidably disposed within the elongate enclosure of a luminaire. In an illustrative example, the end cap may
Embodiments relate generally to methods and systems for providing a bias mechanism for a momentary toggle switch. A toggle switch may comprise a housing; a plurality of contacts disposed within the housing; an actuating lever
Apparatus and associated methods relate to a flexible lumbar wear-pad having an external low-friction high-wear-resistance surface, the lumbar wear-pad configured to be replaceably coupled to the lower back region of a belted fall-protection safety harness.
