    摘要： Glazing articles that reduce glare include a glazing substrate, and a reflective polarizing film article attached to the glazing substrate. The reflective polarizing film article includes a reflective polarizing film, and a reflection inhibitor layer. The reflective polarizing film articles reduce transmission of polarized light with a polarization block axis that is horizontal, and reduce horizontally polarized light to 90% or less of the horizontally polarized incident visible light. The reflective polarizing film may include a multi-layer film construction. The reflection inhibitor layer may include a tinted layer or an absorptive polarizer layer. Glazing units that reduce glare include at least one glazing substrate, at least one reflective polarizing film, and at least one reflection inhibitor layer. The glazing substrate, reflective polarizing film, and reflection inhibitor layer may or may not be in contact with one another.

    摘要： An electrochemical desalination system includes a first and a second electrochemical device and a controller. The first and second electrochemical devices each comprises a electrochemical desalination module comprising at least one pair of electrodes and a compartment between each pair of electrodes for receiving an electrolyte solution. Each of the first and second electrochemical desalination devices comprises a plurality of successive operation cycles. Each cycle comprises a charging mode of operation for charging each pair of electrodes and for adsorbing ions in the electrolyte solution on the electrodes, and a discharging mode of operation for discharging the pair of electrodes and for desorbing ions from the pair of electrodes. The controller is configured to control the system that the first and second electrochemical desalination devices have interleaved charging and discharging modes of operation. One of the first and second electrochemical desalination devices is in a discharging mode and the at least one pair of electrodes release electrical current, while the other of the first and second electrochemical desalination devices is in a charging mode of operation and receives the electrical current released from said one of the first and second electrochemical desalination device.

    摘要： A projection system is disclosed, in which a screen may have improved rejection of ambient light by having a high reflectivity at low angles of incidence for a polarization parallel to that of the projector, a low reflectivity at high angles of incidence for a polarization parallel to that of the projector, and a low reflectivity at both low and high angles of incidence for a polarization perpendicular to that of the projector. In some embodiments, for p-polarized light polarized parallel to the projector, the power reflectivity is high at low angles of incidence and decreases to a low value at high angles of incidence. In some embodiments, for p-polarized light polarized perpendicular to the projector, the power reflectivity is low at low angles of incidence. In some embodiments, for s-polarized light polarized perpendicular to the projector, the power reflectivity remains low at all angles of incidence. In some embodiments, the screen includes a thin film structure that has alternating quarter-wave layers of isotropic and birefringent materials, which are refractive-index-matched for light polarized perpendicular to the projector, which form a high reflector at normal incidence for light polarized parallel to the projector, and which exhibit Brewster's angle effects for p-polarized light polarized parallel to the projector at high angles of incidence. The Brewster's angle effect may be reached by use of a light-scattering layer that increases the effective incident refractive index.
