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 padded book panel which utilizes three flat chipboard layers between which are positioned an upper undulating layer and a lower undulating layer.The undulating layers are of generally longer fiber length than the flat chipboard layers.In a preferred embodiment, the upper undulating layer has longer arms or flutes thereon so that, when passed through a treating pressure roller, the arms of the upper undulating layer are permanently bent or creased. The arms of the lower undulating layer, being of shorter height, are not bent during the roller treating softening process.The resulting structure is then utilized as an economically manufactured and high-quality padded book panel.

Abstract: A method of producing paperboard and a paperboard structure wherein the grain lines of upper and lower chipboard panels are aligned at right angles in relation to the undulations formed in a midstratum layer to yield an overall panel assembly having a high degree of bending resistance.The invention also relates generally to a panel assembly having a particular novel layered construction. In place of a conventional solid chipboard laminated construction, an undulated midstratum layer is utilized in such manner that air cells or pockets are formed within the structure. An overlayer and an underlayer are adhesively applied to the undulated midstratum layer. The invention results in a panel assembly which may be much more economically manufactured while yielding superior end product strength and durability. The invention has widespread utility as a superior substitute for the currently used solid laminated chipboard design.

Abstract: A vehicle sunshield fabricated of a rollable single face corrugated fiberboard material with printed material applied to one side thereof. The one-piece design includes left and right sections or zones which are structured to be held in place by the conventional pivotable visors used in automotive vehicles. The one-piece design further includes a central section or zone (22) which has formed at the top thereof a mirror cutout portion and a reduced width mirror post cutout portion to aid in the ease of installation and use of the device.
