Abstract: An skirt having an upper portion and a lower portion covers at least components of a suspension of an active suspension seat, wherein the upper portion is coupled to an upper frame of the suspension and includes at least an upper front portion having a curved cross-section, and wherein the lower portion is coupled to a lower frame of the suspension and includes a lower front portion that has an upper edge and that has either a curved or L-shape cross-section.

Abstract: An active suspension seat is mounted to a floor of a vehicle with a floor plate having a lower portion through which is formed a first plurality of apertures positioned about the lower portion to correspond to the manner in which mounting features are positioned about the floor of the vehicle, and having an upper portion through which is formed a second plurality of apertures positioned about the upper portion to correspond to the manner in which apertures are positioned about a lower frame of the active suspension seat, and to enable the active suspension seat to be coupled to the floor plate by inserting fasteners through the second plurality of apertures from locations external to the lower frame.

Abstract: Selective reflective optical apparatus includes a projection screen. The projection screen has structure constructed and arranged to selectively reflect only incident optical energy of a predetermined number of narrow bands of optical wavelength regions.

Abstract: A projection screen that includes a multilayer, multiband, single stack device that selectively reflects light with wavelengths in plurality of narrow wavelength bands, and methods for making the screen. The multilayer, multiband, single stack device may be an etalon device. The multiple layers may be deposited on a diffusing substrate. The projection screen may also include a polarizer that coacts with a projector. The projector polarizes the projected light in the narrow wavelength bands into the same polarity and the screen reflects the light with the same polarization and does not reflect light of another polarization. The polarizer may include substrate with a thin polarizing coating. The screen may include a matte surfaced diffuser.
