Abstract: A laser projector compatible with wavelength multiplexing passive filter techniques comprises a scanning system and a plurality of laser systems, wherein each output beam of light has a unique wavelength and is similar in hue to at least one other output beam of light, wherein the output beam of light is received and deflected by a scanning system to produce stereoscopic 3D images on a projection surface. The integrity of the inherent properties of coherent laser light sources, in particular collimation, monochromacity, and speckle, is maintained, contributing to the unique appearance of the resulting stereoscopic images.

Abstract: A planar microfluidic membraneless flow cell. The design eliminates the need for a mechanical membrane, such as a polyelectrolyte membrane (PEM) in a fuel cell, by providing a flow channel in which laminar flow regimes exist in two fluids flowing in mutual contact to form a “virtual interface” in the flow channel. In the flow cell, diffusion at the interface is the only mode of mass transport between the two fluids. In a fuel cell embodiment, a planar design provides to large contact areas between the two streams, which are fuel and oxidant streams, and between each stream and a respective electrode. In some embodiments, silicon microchannels, of fixed length and variable width and height, have been used to generate power using formic acid as fuel and oxygen as oxidant. Power densities on the order of 180 ?W/cm2 have been obtained using this planar design.
