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: A radiant heating and blocking shade system for a sunroof of a vehicle includes a first roller configured to be mounted adjacent to one end of a sunroof of a vehicle. A second roller is mounted adjacent to the first roller between the first roller and the sunroof. A radiant heating shade is at least partially wound around the first roller. The radiant heating shade has a deployed position and a retracted position. A blocking shade is at least partially wound around the second roller. The blocking shade has a deployed position and a retracted position. The blocking shade is arranged parallel to and spaced from the radiant heating shade between the radiant heating shade and the sunroof when the blocking shade and the radiant heating shade are in the deployed position.

Abstract: Disclosed herein is a battery module comprising a plurality of battery cells encased in an outer shell. The outer shell has disposed on an inner surface a flame retardant layer that comprises expandable graphite. The expandable graphite is operative to expand during an thermal event that results in an increase in battery module temperature. Disclosed herein too is a method comprising disposing in a battery module a flame retardant layer; where the battery module comprises a plurality of battery cells encased in an outer shell. The outer shell has disposed on an inner surface a flame retardant layer that comprises expandable graphite. The expandable graphite is operative to expand during an thermal event that results in an increase in battery module temperature.

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 battery cell thermal conditioning system for a vehicle includes a battery pack having multiple battery cells. Multiple foam layers are individually positioned between first successive ones of the battery cells. A first carbon nanotube sheet is positioned in direct contact with one of the battery cells on a first side of the foam layers and a second carbon nanotube sheet is positioned in direct contact with a different one of the battery cells on a second side of the foam layers. A cooling plate is positioned between second successive ones of the battery cells. A controller directs current flow to the first carbon nanotube sheet and the second carbon nanotube sheet when a temperature of the one of the battery cells contacted by the carbon nanotube sheet drops below a predetermined threshold temperature.

Abstract: Aspects of the disclosure include hybrid thermal management systems configured to control an operating temperature of a liquid crystal on silicon (LCoS) based head-up display (HUD) unit. An exemplary thermal management system can include a liquid crystal on silicon layer and a phase change material on a surface of the liquid crystal on silicon layer. A thermoelectric device is positioned in direct contact with the phase change material and a heat sink is positioned on a surface of the thermoelectric device. The thermal management system can further include a controller configured to adjust a thermoelectric device current of the thermoelectric device responsive to a temperature of the liquid crystal on silicon layer.

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.
