A handheld device (), including a projector module () which includes a light source having a laser or at least one light emitting diode; a thermal management system which includes a heat collector () formed of a material having a thermo-mechanical design constant of at least 10 mm-W/m*K and having a non-planar shape, the heat collector in thermal contact with the light source; a heat spreader () having a surface area at least 1.5 times that of the surface area of the heat collector and a thermo-mechanical design constant of at least 10 mm-W/m*K, the heat spreader positioned in thermal contact with the heat collector, wherein thermo-mechanical design constant of a material is defined by thermal conductivity of the material multiplied by its average thickness.

Thermal management for handheld projectors

The invention relates to polymeric resin blends containing polyelectrolyte resins blended into a polymer or copolymer matrix. Specifically, the polyelectrolyte resins are (co)polymers without hydrolyzable groups. The matrix polymer is a tough, and highly chemical-resistant (co)polymer, preferably a fluoropolymer. The polymeric resin blend is useful for forming films, and especially films useful for MEAs for use in fuel cells.
