Abstract: A melt-processable conductive material including a first continuous phase, a second continuous phase and a non-continuous phase. The first continuous phase includes a first polymer, the second continuous phase includes a second polymer, and the non-continuous phase includes a third polymer. The second continuous phase is co-continuous with the first continuous phase and the non-continuous phase is substantially contained within the first continuous phase. A plurality of conductive particles is distributed in the first polymer or at a boundary between the first continuous phase and the second continuous phase. The conductive particles form a conductive network.

Abstract: Various embodiments of a respirator that includes a harness, a mask body, and an exhalation valve are disclosed. The exhalation valve can include a valve seat and a flexible flap that is in engagement with the valve seat. The flexible flap can have one or more materials that can cause the flap to flash when moving from a closed position to an open position or vice versa. The flashing valve can make it easier for a user to ascertain whether the valve is operating properly.

IPC: G02B5/136
Abstract: A retroreflective system is disclosed that includes a retroreflective sheet for retroreflecting light, and a light control film disposed on the retroreflective sheet. For a first wavelength, light incident on the light control film at each of a first and second angles of incidence is retroreflected. For a second wavelength, light incident on the light control film at the first, but not the second, angle of incidence is retroreflected.
