A drying apparatus usable with a printing system includes a housing, a first set of radiative heating elements, a second set of radiative heating elements, and an air handling device. The housing includes a front region and a rear region adjacent to the front region. The front region includes an inlet to receive media. The rear region includes an outlet to pass media there through. The first set of radiative heating elements is disposed within the front region to heat the media. The second set of radiative heating elements is disposed within the rear region to heat the media. The air handling device is disposed across from the second set of radiative heating elements to jet air within the rear region to cool the media prior to the media being passed through the outlet.

A method of forming an interface between components having different rates of volumetric expansion includes forming an interface surface of the interface with respect to a center of growth such that slippage occurs at the interface between the components during volumetric expansion.

A fuel cell layer includes a substrate, an array of fuel cells each having an anode, a cathode, and an electrolyte disposed on the substrate, conductors electrically coupled to the fuel cell array, a fuel flow channel defined in an anode side of the substrate; and a cathode air flow channel defined in a cathode side of the substrate.

Multi-cell fuel cell layer and system

A fuel cell assembly including a liquid metal seal and/or a liquid metal interconnect.

Fuel cell assembly and method of making the same

A fuel cell assembly includes a plurality of opposing fuel cell stacks. Each of the fuel stacks has a plurality of fuel cells in which each fuel cell has an anode, a cathode, and an electrolyte. The fuel cell assembly further includes a spacing member disposed between the fuel cell stacks thereby defining a fluidic cavity.

Fuel cell stack assembly and method of fabrication

An inkjet pen is disclosed having an interior chamber containing a pressure regulator. A filter within the interior chamber substantially surrounds the pressure regulator, providing a large filter surface area, and hence a low resistance to ink flow. The filter may be formed of a pleated filter material; the filter material may be retained by a rigid ink passage flange and a filter cap.

A printhead assembly includes a carrier having a fluid manifold defined therein, a plurality of printhead dies each mounted on the carrier and communicating with the fluid manifold, and a fluid delivery assembly coupled with the carrier and communicating with the fluid manifold.
