Abstract: A heating apparatus is provided. The heating apparatus includes a positive temperature coefficient (PTC) heating element and a power controller configured to generate and apply a pulse width modified signal to the PTC heating element. The power controller is configured to vary a current of the pulse width modified signal linearly with respect to a temperature of a space being heated by the PTC heating element.

Abstract: A climate control device includes a radiant heater for radiating heat and a porous material attached to the radiant heater. The porous material desorbs a plurality of water molecules, in response to the porous material receiving heat from the radiant heater and raising a temperature of the water molecules in the porous material to a boiling temperature threshold. The porous material adsorbs the water molecules in response to the temperature of the water molecules falling below the boiling temperature threshold.

Abstract: Systems and methods are provided for radiant heating by PTC radiant patches. A radiant heating system for warming an occupant of an enclosed space includes patches to radiate heat into the enclosed space toward the occupant. A power supply supplies electric power to the patches. A controller controls the electric power supplied to the patches based on a temperature in the enclosed space and locations of the patches within the enclosed space.

Abstract: A plasma actuator includes a first electrode disposed on a substrate, covered by a dielectric layer, and a second electrode disposed on the dielectric layer. In operation, the plasma actuator creates a plasma region, altering air flowing over the actuator. The plasma actuator in various embodiments: has no moving parts, helps to improve fuel economy by reducing aerodynamic drag, improves vehicle stability control under severe unsteady flow environments, reduces wind noise around a vehicle on which the actuator is used, and reduces emission and CO2 foot print through the fuel economy improvement.

Abstract: Air management systems are provided for optimizing airflow in laser welding with deflectors. A system for a welder includes a blower to generate an airflow stream. A plenum receives the airflow stream, directs it toward the workpiece, and defines an outlet facing the workpiece to expel the airflow stream toward the workpiece. A deflector adjacent the outlet is formed as a conical section converging from the plenum toward the workpiece, and is defined by an angled wall with an open center. The deflector concentrates the airflow stream to impart a velocity increase to the airflow stream after leaving the outlet and to impart a favorable directional component to the airflow stream toward a weld zone, as well as protecting the laser lens by increasing the downward momentum force of the air stream to eliminate the potential of spatter impinging the lens.

Abstract: Radiant heating systems for warming an occupant of an enclosed space. The system includes a component with a surface that faces the occupant. The surface defines an A-surface quality meaning the surface is visible and is designed with styling objectives to have an aesthetic appearance. Conductive strands are exposed at the surface and a power supply supplies electric power to the conductive strands. A controller controls the electric power supplied to the conductive strands.
