Abstract: In one example, a climate control system for a printer includes: an air flow path from an intake for receiving warmer, dirtier aft from a printing area of the printer to an exhaust for returning cooler, cleaner air to the printing area of the printer; a first heat exchanger in the flow path for exchanging heat between warmer air coming from the intake and cooler air going to the exhaust; and a second heat exchanger in the flow path for receiving warmer, dirtier air from the first heat exchanger and passing cooler, cleaner air to the first heat exchanger. The second heat exchanger is configured to cool the air to a predetermined dew point temperature corresponding to a desired level of a contaminant in the air.

Abstract: A photoconductive foil sheet applicator applies a photoconductive foil sheet about a circumference of a drum.

Abstract: A cleaning station includes a fluid input which introduces a passive flow of fluid into a trough and a slit which provides an outlet through which the fluid exits the trough. A wetting roller rotates in a cylindrical cavity to form a viscous fluid pump which draws the fluid through the slit to form a fluid film on an outer surface of the wetting roller.

Abstract: A self-powered flashlight includes a pair of end lights and a ring of circumferential lights which are selectively energized by a pushbutton switch. The module includes a housing and an inner electronic module. The inner module includes a display for displaying time and temperature as well as a transceiver such as a cell phone and GPS unit which are activated by a switch. The switch permits selection of one of a warning mode, an alert mode or an SOS mode.

Abstract: A self-powered safety module includes a pair of end lights and a ring of circumferential lights which are selectively energized by a pushbutton switch. The module includes a housing and an inner electronic module. The inner module includes an LED display for displaying time and temperature as well as a transceiver such as a cell phone and GPS unit which are activated by a switch for an emergency mode. The switch permits selection of one of a warning mode and an alert mode, or an SOS mode.
